Cell Hits 45nm, PS3 Price Drop Likely to Follow
Septimus writes "At this weeks ISSCC, IBM announced that the Cell CPU used in the PlayStation 3 will soon make the transition to IBM's next-gen 45nm high-k process. 'The 45nm Cell will use about 40 percent less power than its 65nm predecessor, and its die area will be reduced by 34 percent. The greatly reduced power budget will cut down on the amount of active cooling required by the console, which in turn will make it cheaper to produce and more reliable (this means fewer warrantied returns). Also affecting Sony's per-unit cost is the reduction in overall die size. A smaller die means a smaller, cheaper package; it also means that yields will be better and that each chip will cost less overall.'"
I don't know what it is about measuring things in nanometers and terabytes that gives me such a hardon.
Thank you IBM.
PS: Please don't put Skynet online.
Virginia is for lovers. EVE is for griefers.
My only question is, will this reduce the cost?
Since when does going to a smaller process increase yields?
As far as active cooling....why not have an external power supply and then you'd need even less cooling.
You know what means, don't you?
Actually, I think that there are too many processors and cpu's. Too much internal memory. I yearn for the 8086 chip still. Or an IBM 360 mainframe. Now that was computing.
This would be a great thing if they allow PS3/Linux users to access 7 of 8 SPUs instead of only six.
Otherwise, it's nice but not that big a deal...
This fits in well with the rumors of a slim version of the PS3 in the works. See here for more details.
Curiosity was framed, Ignorance killed the cat.
A price drop would be nice (though the PS3 is now competitive), but the more interesting bit is when is the PS3 slim going to appear. All the pieces are in place for a slim. Sony have been aggressively shrinking the motherboard in the PS3, and the chip size has dropped from 90nm, to 65nm and now 45nm. All that means less power (smaller PSU) and less heat (less fans & heatsinks). There have been other announcements such as thinner blu ray reader headers. It can only be a matter of time before a slim and I think it will hit before the holidays this year. I think it will sell by the shitload too when it does appear. The question is will we see a slim 360 to compete with it? I think there must be a lot of empty space in the 360 too.
The article mentions the cost savings to Sony (maybe they'll be passed on to the consumer...two or three years from now), but the real kicker is at the bottom where IBM apparently had to maintain cycle compatibility with the old chip to make sure they don't break any games. They didn't use the die shrink to optimize or enhance any parts of the chip like you normally would. The supercomputer folks might end up losing out a bit in an effort to keep the game console folks happy.
I read the internet for the articles.
Which is another important factor in bringing the price down. Percentage-wise with more die per wafer yields may go up as well; but in the end yields will be dependent on other things such as how good IBM is with its 45nm process.
Think it will be possible to swap out the chip/board but still save my emotion engine? i cant be without my beloved emotion engine; i'll have nothing left to gloat about to my friends who don't have it now.
~> FatJackson
for a PS3 price drop, but.... when's it going to happen?
It would be really great that they are moving to a smaller process, (/me takes deep breath)
IF THEY WOULD SELL YOU THE DAMN THINGS!
Where I work, we approached them to try to buy Cell processors for our equipment: the SPUs would make dandy DSP replacements, and we really could use the closer coupling of the processors instead of having a bunch of DSPs and spending all our time schlepping data around.
IBM wouldn't sell us any modules, wouldn't let us design our own CPU board, nothing. They seem supremely uninterested in actually getting these out into the hands of anybody other than their own divisions and Sony.
HEY IBM! How about you guys release these in a MicroTCA formfactor, or as a module that can be integrated into a MicroTCA?
www.eFax.com are spammers
And then, when chips are so small, they will live inside our cells. And we will merge with the technology. And I will be very, very scared.

Is the fact they've dropped hardware PS2 emulation.
[Fuck Beta]
o0t!
If' they're dropping cooling components due to lower heat output, I wonder if that means this picture is for real.
Moore's law is dead. Atoms aren't getting any smaller. With 5 atoms thick, when you try and go to 2.5 atoms thick, let me know and I'll get far away.
It isn't the smaller process that increases yields, it is the fact that the ensuing smaller die takes up less space on the wafer. Less wafer real-estate == less chance that a defect in the wafer will occupy the space of a particular chip.
For instance, say one 300mm wafer has 50 defects evenly distributed over it's surface, and one wafer can hold 100 chips with the old process, 200 with the new. The 10 defects result in a 50% yield with the old process, a 75% yield with the new process.
That said, yes, almost all new processes take a little while to work out the bugs. But after the bugs are worked out, you can achieve much higher yields...

From the article: "So IBM may have suckered Sony into buying a supercomputing coprocessor disguised as a gaming chip, but it looks like Sony could get the last laugh." Why would they? IBM is selling more than ever.
The reason is that wafer size doesn't change. I don't remember what is current, 8 inch I believe (that's the largest I've seen) but regardless. So when you reduce the size of an individual chip, you get more chips per wafer. Now unless the percentage of chips that fail increases, that means you get a better yield/wafer.
Well cost is based per wafer. It doesn't cost any more to make a wafer with 1000 small chips than it does to make one with 4 big chips. In either case it is the same size wafer, same mask, same process, etc.
Now yield could go down if a company has problems with a new process. Suppose that the old process yields 10% non-working chips per wafer. You get a new process that yields 20% more chips per wafer than the old one, however now 50% of them are non-working. That would equal a lower yield, despite the more chips per wafer.
However assuming a roughly equal failure rate, shrinking the die size will increase the yield.
The article linked to says power consumption will be 40% lower than the 65nm predecessor, but I haven't been able to find a reliable figure for the 65nm power consumption. Does anyone have that or a link? All I've found online are puff-pieces saying the power is very low or may be in the future, but no actual spec.
Simply put, they reduce the cost of production, they lose less money on each one they sell. Considering the Playstation 3 is slowly gaining market share at it's current price, they have no need to drop the price right away.

Does anyone have insider or otherwise info on how much more rulesets does the 45nm t ech have, compared to the 65nm?
"The agriculture ministry is not in charge of Gundam" - Japanese ministry official.
I remember the biggest problem with the PS3's availability and cost was the blue laser (as it has low yields and is expensive to make). Sony was already taking a hit on cost, since a stand-alone Blu Ray player in November actually cost about the same or more.
It's nice that the cell processor is lowering in cost, but I'm not sure that it ever was a significant enough percentage of the unit cost to see a drop of more then a few tens of dollars.
Less heat generated by the processor also means that a smaller fan is needed to cool it, which in turn means less background noise when you are gaming or watching high-definition movies.
Say it with me:
Will it blend?
Pancakes. Oh I blew it.
Relevance of CBE beyond PS3 of course depends in large degree on its computing performance. For the applications I've looked at, I haven't been very impressed. They say it does 204GFLOPS, but approaching that requires being able to use all multiply-add instructions, which count as two operations. (Some sources say the two operations per clock cycle per SPU is due to there being two pipelines, however, only one of the pipelines handles arithmentic operations and the other is exclusively for load, store, control, and a few shift operations.) Also, it seems to take a lot of select, shift, and shuffle instructions to make efficient use of the quadword (SIMD) instructions. With Xeon and Opteron, use of the quadword instructions seems to require far fewer other additional cycles. And this is with floats, with instruction related stalls completely eliminated on CBE through careful loop unrolling and other methods. (The quadword instructions have 6 cycle latencies.) I can only get performance comparable to 2 quad-core Xeons, which doesn't seem that good considering what is advertized, and considering the 4x difference in the peak performance specs. And CBE does much worse where double precision is necessary, with 6 cycle stalls being unaviodable on every instruction. It seems overblown. Comments?
I'm not sure about current hardware revisions... but the 360 I have... not very much space to go around.
But with some hard work it appears you can thin it out a bit as demonstrated in the Xbox360 Laptop. My only question would be the failure rates on these things due to heat issues. As it's already been shown your standard store bought Xbox is affected by the excessive GPU heat causing motherboard warping and extra stress to solder points.
I'm sick of following my dreams. I'm just going to ask where they're goin' and hook up with 'em later.
This assumes that the chips are small enough that there are never 2 or more defects per wafer. It may be possible that a bigger chip that would have 2 defects is split into 2 chips each with one defect each. Thus, the yield increases in a somewhat, but not completely linear fashion.
Even those who arrange and design shrubberies are under considerable economic stress at this period in history.
Now that blu-ray has won the format wars and a PS3 gives you a gaming console AND a blu-ray player in one bundle, why would Sony lower costs? Wouldn't they just e happy with the higher profits?
What a stupid inflammatory conclusion. A remap is just what it is - a remap. The article blames IBM for missing the "opportunity" to spend a lot of money on tweaks, i.e. on logic design and verification, and to screw up compatibility for Sony at the same time.
They gave away too much info. Now we will expect an affordable, reliable game console.
It is dangerous to be right when the government is wrong.
Last I heard, Sony was still losing a ton of money on every PS3 they sold. So even if this upgrade makes it significantly cheaper to manufacture PS3s, I don't see why that would lead to a drop in retail price.
If anything, I'd guess Sony wants to keep the PS3 at its current price, now that they've basically won the next-gen DVD skirmish. Plenty of people who want Blu-Ray players probably already see the PS3 as a good choice (just like I bought a PS2 to play DVDs back in the days of yore).
Not so long as the consoles continue to sell at the current price. Sony charges what they think people are willing to pay, no more and no less.
Nowadays, one of the hottest components in a computer (and consoles) is the GPU.
Most of the XBox 360 problems come from a very hot GPU situated under the DVD drive.
I think taht the GPU used in the PlayStation3 is a 90nm derivative from the GeForce 7800 (a quite hungry GPU) (you can see it in http://en.wikipedia.org/wiki/RSX_'Reality_Synthesizer' ). I think that this GPU should be shrink into another process before creating a "Slim & Lite" PS3...
That's great and all but let's also hear about what's happening with Nvidia's contributed RSX. When will it his 45nm and be included in the PS3? I'd reckon that a 45nm Cell and 65nm (or heaven forbid 90nm!) in the PS3 would still generate a whack of heat. I understand that Nvidia has their latest iteration of GPU's coming out at 45nm so I wouldn't think this to be a stretch. Any official word?
Anyone know what the die size of the XBox 360's IBM cpu is? Wouldn't be surprised if it's the same, of course.
Just because the PS3 parts are going through nothing more than a process shrink, it doesn't mean the cell platform will not have an iteration soon with new features amenable to those supercomputer folks. Many processor families are maintained concurrently and refreshed industry (i.e NetBurst processors had new iterations concurrent to the Core architecture being maintained), I doubt Cell would magically be exempt from that, particularly with some of the big dollar supercomputing folks seemingly keenly interested.
The redundancy of the Cell's 8 SPUs (DSP coprocessors) is the main point of the Cell's design. Defective SPUs (nearly always from dust particles in the nearly - but not quite - perfect "clean rooms" in which they're manufactured) can be tested and turned off as they roll off the assembly line. The shut down SPUs are even physically disconnected from power by hard fuses, so they don't cost any performance in operation. The perfect Cells with 8 SPUs cost the most, in high-end IBM RS/6000 workstations (and some blade servers). 7 SPUs go into PS3s. The rest of the yield, supposedly down to a single SPU (but even 0 SPUs still have a 3.2GHz PPC and superfast IO), go into HDTVs and other consumer electronics. All of the yield gets sold, instead of a fraction in older manufacturing processes.
So smaller dies don't really affect Cell yields. Smaller dies just mean smaller parts of the wafer that would get spoiled by a single defect, which is already taken care of with the redundant SPUs.
In fact, smaller dies mean multiple defects are less likely to land on a single die. Which means that more Cells would turn into low-SPU, cheaper Cells. While larger dies would concentrate multiple defects into a single dies, by landing on a single die more often, leaving more perfect Cells getting the highest prices.
45nm does mean more Cells, at any defect rate, per wafer. Which means, for the same number of defects per wafer, more dies per wafer. So there is a yield increase, but not for the same reasons as traditional ones. And of course 45nm has so many other valuable benefits, like speed, and more transistors if they keep the same die size, that the move is very valuable overall.

The PS3 is interesting because it's so much power in such a cheap box, but it's subsidized by Sony. I think Sony will be lowering prices less while reducing the subsidy more.
But where are the Cell PCs already? The PS3 is cute, but it's locked down with a Sony hypervisor, it's got no PCI or other expansion, only a single SATA connector, and a puny 512MB hardwired RAM (its Cell can rip through 512MB, peforming 64bit floating point math on it all, in under 0.0025s). Its RSX video chip is locked out from Linux, so no HW acceleration (and no addon videocard is possible).
IBM is now cranking out these chips. It lost Apple, its biggest CPU (PPC) customer, to Intel. Where's a PC built on a Cell that includes PCI-e, expandible XDR RAM, Gb-e networking, and a more open nVidia graphics card (or two)? Since the Cell is cheap due to its higher yields, a $1000 Cell PC could make a $1000 Intel PC (Mac or Windows/Linux/etc) look like a 286 with its extremely high speeds. Sony has proven it can be mass manufactured with mostly commodity parts for under $750.
Since Ubuntu already runs on Cell, a cheap Windows killer could take the Cell architecture to the top of the CPU stakes in record time from release. It would be a much easier/cheaper/faster target for porting PS3 games than Intel PCs. Apple, which supposedly dropped PPC for Intel because of heat:performance limitations, would have to look seriously at a return to PPC, especially since 45nm Cell with only a few SPUs could be a perfect fit for an iPhone successor. If not from Apple, then from someone smart enough to use Cell in the biggest market of all.

So I won't be able to buy a full 2 Wii's for the price of a PS3, only 1.8? Getting closer to reasonable...
"Teach a man to build a fire, and he's warm for a day. Set a man on fire and he's warm for the rest of his life."
PS3 CAN take off.. Price it at $299.00 including a game and 2 controllers.
How about a Ferrari with a condo in Dubai? That sure as hell will get units moving! Seriously man, get real. Considering a controller costs about as much as a game nowadays, you can't even find a similar 360 bundle that cheap.
Drop all game prices to below $50.00
If you're putting Sony to task for $60 new-releases, then hold everybody accountable. Anything else is unabashed fanboyism.
until they do that, it will stay as the wannabe console that nobody is buying.
That's weird, according to fact the PS3 sales are on par with the 360 at the same point in their respective life-cycles. But facts are SO over-rated.
Hahahahahahah Yes Finallllllly!!!! I can has its!!
And because of the new and improved processor that is smaller and runs cooler and more reliably we are announcing a 23% price increase for fall of 2008 ;)
Moore's law governs transistor devices, how very 21st century. There's still molecular valves yet, and sexy seb-mesons!
I think the general slant of the question was whether the price drops now as a result of this, or does Sony put the saving toward reducing their losses on each system sold.
Sony doesn't lose anything on any PS3 sold - I'm not sure they ever did, but they certainly do not today. This processor shrinkage is just another in many steps that Sony has already undertaken to reduce the cost of the PS3 to assemble.
People tend to discount Sony, but what they do not understand is that Sony is very, very good at ratcheting down costs constantly while still keeping quality pretty high. That is a powerful force even if they make other mistakes along the way.

A 40% drop in heat will make a huge difference in the suitability for business application of the PS3. (Before you say that business use of a PS3 is contradictory, please consider the accommodation industry.)
The instant they can get a PS3 (or an Xbox) that does not spew heat and use fans akin to a Boeing, it will have a place in the entertainment centers in luxury accommodation suites around the world. The region free PS3 game discs will seal the deal. Surfing internet on the TV and being able to show photos straight from your memory card is also a plus.
Late last year, we tried rolling the current model of PS3s into some guest suites. In the end there was no way to accomplish this without a major retooling of the entertainment centers, costing hundreds of dollars extra per unit. In one case the excess heat generated by the PS3 caused the TV to overheat!!
The drop in power bills will also be a big plus, as guests will generally never be bothered to switch off an appliance. I had thought that the PS3s were supposed to automatically regulate the amount of processor power needed. But they seem to run as many fans even when idling at the top menu.
For business use the maintainability and operation costs are a much bigger factor than the original cost per unit. If they can actually get the heat under control, Sony will break into a huge new market of corporate clients.
Particularly if they were savage, bloodythirsty Aztec chihuahuas who I could order off the cart at a moment's notice to devour anyone saying "Aww, wook at the cute puppies".
Help poke pirates in the eyepatch, arr.
That nVidia is on 65nm, I'd expect they'd move the 7800 to that process, if they haven't already, for the PS3.
XML is like violence. If it doesn't solve the problem, use more.
That we can't have quad core Intel processors, since Intel has to manufacture chips for laptops which need lower power utilization than is currently not feasible with quad core. Oh wait, Intel manufactures different variations of the same architecture to suit different products/environments. Power chips, likewise, are used in tiny embedded appliances with low TDP and other crippling situations, but also at extremely high TDP in Unix servers, with many more capabilities.
It's obviously a bad move to presume IBM would be so stupid as to lock themselves into only ever implementing one specific instance of a design without variation if they want to deviate. I agree with the other post, seemingly pointing and laughing at IBM over this 'limitation' is going to backfire if IBM considers it a viable platform outside of gaming and releases a serious variant of the product as this advancement gets rolled out in parallel.
XML is like violence. If it doesn't solve the problem, use more.
Much to AMDs dismay, the new Intel 45nm chips are remarkably good. Only 4 watts idle and 50W when at max load and also a bit faster per clock. That idle figure is quite amazing considering 20-30W was considered good a generation or two ago.
So if Sony gets similar benefits from 4nm+high k, the new PS3 will use much less power. They managed to get it to work without active cooling as it was, so this should give them a lot of headroom to shrink the box or do something new (build in PS2 hardware again would be a good idea...).

Well its interesting that IBM is making it cheaper for Sonly to make a gaming console. That's all the Cell is good for in a PS3. If you scoff at the previous sentence, REREAD IT, because its true! I investigated using a PS3 as a device for doing scan line rendering as part of a cluster. I bought one. Its useless. Sure it runs Linux almost as quickly as an 800 MHz pentium III. ---Almost as quickly. And without accelerated graphics. All of the "SUPERCOMPUTER SPUS" that should come with the cell, are there, but IBM hides the middleware to turn them on behind a draconian licensing scheme that would make Joseph Goebbels flush. Couple that with a tiny little bit of memory, not large enough to do anything really useful, and even though its really fast, the sole company that makes it, doesn't make anything bigger so you can't upgrade it, one of the SPU's in the PS3 is stillborn at the foundry (second rate, 7 out of 8 ain't bad chips make it to the PS3), and Sonly kills off another one by running a hypervisor on one of them to keep all of the others in line (just when you wanted to do something really useful). Despite what Sonly says (and yes, I know about the correct spelling and I *MEAN* to combine Sony with only), you can only use this box as a game console, not a computer, not by a damn long shot! The hardware is crippled, the software is crippled. Go buy a real computer and you will get real results. The Cell was a nice experiment, and perhaps some of what was learned will make it into real computer processors one day, where people can actually use the technology. Until then, I guess the PS3 is an ok game console. Not worth the price when considering the WII though.
Just wonder if there will be something like VIA's Mini ITX with CELL processor on board available somewhere in future.

Imagine building own MythTV with that.
Ultimate PVR!
Processor dependent software (for the Mac) was essentially irrelevant at the time of the switch.
Not quite, since the emulator will never be as fast as the real CPU (ergo, executing binaries that can't be re-compiled) but that was not an argument in favor of the x86 at that time.
One might argue that drivers don't have to be re-written as much, I suppose, but the reality of driver availability for the Mac has not really changed, as near as I can tell.
The switch to iNTEL seems like a great thing, but it will turn into a blind alley within five years. The x86 architecture has some serious flaws that iNTEL has been able to fake their way past by pushing the speed, but the wall stands in front of us, and the wall requires a different architecture to get through.

does sound ridiculous, but I'm imagining 50 chihuahuas and one clydesdale and I'm thinking, if I could figure out the harness problem, and the problem of getting them all pulling in the same direction, I'd at least like to give it a try once.
As a rough guess, fifty chihuahua-power is probably greater than one horsepower.
How many Alaskan huskies equal a clydesdale? I wonder if anyone has mentioned horsepower per husky on wikipedia.
Yeah, off-topic, except that the harness problem is somewhat analogous to the problem of writing efficient muli-(erm)threading software.

Here I am, replying to AC... Slow day indeed.
Sorry, but you are wrong (as your moderation points out).
You can buy a PS3 to do numerics and the Cell inside it is an average performer. Not bad at all for under $1000.
But, if you need to upgrade (and consider your workload is heavily parallelized and optimized for the SPUs because it already runs on your PS3's SPUs) you can buy one or more IBM QS21 blades and a suitable chassis. It's obvious these new Cells will be in these blades as soon as they become available. In the blades, the Cell is not limited as it is in the PS3, there is plenty of memory for the PPUs and you can run all your SPUs at full throttle if your data and programs demand it. And, while you are at it, you can add POWER or x86 blades to the chassis as well as Linux does not run particularly fast on the Cell PPUs and you may want a fast machine to feed the Cell node.
Sorry if you wanted current supercomputer power on the cheap. The PS3 is good enough for a lot of stuff and a lot cheaper than anything that approaches its numeric performance.

FTA: "So IBM may have suckered Sony into buying a supercomputing coprocessor disguised as a gaming chip".
Well no, not really. Most HPC workloads are double-precision heavy, and while the Cell/BE chip has very good single-precision numbers the double-precision performance isn't very good.
Jeez. You ALWATS get a performance boost when you move to a higher resolution process, that an bugfixes and a few choice tweaks, and you wind up with a significant performance boost. I wonder what the performance boost will do?
They already dropped the price for the reason that their sales were getting pummled by the wii and 360 - I seriously doubt anyone outside the tech sector is going to know what a die shrink means and/or correlate that to a cheaper price.
and also, it seems to me that the PS3, at 399 is a great deal - considering it has a blue-ray player in it and rivals the strongest console systems, graphics wise. With that being said, the reason I will not buy one of their new versions is it will not play playstation 2 games like its predicessor.
(yes I know my spell check is broken and coffee hasn't kicked in yet.)
