I can't believe anyone still reads that rag. Let me give you a hint: Tom's was bought and sold about 3 years ago. Since that time, it has descended to the ranks of online propaganda host for Intel and a number of other companies. Tricks with driver versions and other such foolery causes them to get benchmark results drastically different from those of almost every other hardware site. No one's bias is more apparent than Tom's himself. Many of the conclusions to their own articles are non-sequitur, and the articles themselves are often little more than a press release for the company doing the most advertising at the time.

The few folks left defending Tom's tend to either be Intelbots or those who like to feel they know something after having read a few dumbed-down for-public-consumption articles from the site. To quote them is to invite laughted upon yourself. You would do well to visit other sites instead for your hardware news. Anandtech, Ace's Hardware, and plenty of other sites provide good, in-depth and trustworthy analysis, as opposed to operating a propaganda machine designed to rake in cash.

"prodution yield is about 30%, it it expected to rise up to 60% after two years of production CPU's are just too complicated to be produced with yield of 98%-99%."

But I say that production yield is about 80%, and is expected to rise up to about 95% after three months. And best of all, I can make up numbers and formulas to make it look very official and correct. When I see Tom in a 'bunny suit' on AMD's FAB floor, I'll believe their 'analysis' of production yields. Until then, he's making up numbers and statstics, adding to the other 73.4% of statistics that are already made up.

The quote from the article, which you have parroted here, is as follows: "However, we doubt that AMD's yield will be any more than 30% - this is based on information from other chip manufacturers that use similar processes."

Now, let's put a little bit of brain power into dissecting this, shall we? First of all, the whole thing is rather vague - using words and phrases like 'we doubt' and 'similar processes'. Secondly, these so-called 'other chip manufacturers' aren't even named. Are they talking about IBM? Or are they talking about 'Phil's CPU FAB', which is run out of a basement in a townhouse in Idaho? Just what are 'similar processes'? Is there someone else making Opteron and Athlon64 CPUs? Someone really ought to tell AMD about that. Or perhaps they're referring to the 130nm 'process', which describes almost nothing about the chips themselves? Maybe they're even talking about the 'process' of getting from wafer to die. Well, so far as I, or anyone I've ever talked to knows, AMD didn't go out and re-write the book on die construction with the K8. The 'process' of getting from wafer to die for K8 isn't that much different from that of K7. I would assume then that Tom's is also asserting that Barton and Thoroughbred yields are also a mere 30%. Or perhaps there's an entirely new made-up number for their yields.

It's amazing how you can throw a few numbers onto a website and everyone will believe you. It's almost as amazing that throwing a few numbers into a post will yield +4 Informative.

It's entirely possible that 64-bit extensions are within Prescott, but disabled. Intel did this with the P4's SMT for quite a while. Xeons had SMT, and it was enabled, while desktop P4s had SMT, and it was disabled. The 64-bit instructions might not yet be finished, to be finalized and debugged in a later stepping of Prescott, or they simply remain dormant, used only as a preliminary testing grounds for Intel, while they're waiting for viable engineering samples of Tejas. To my knowledge, no one has completely accounted for all the new transistors inside the Prescott chips. The speculative execution enhancements, larger cache, longer pipeline, etc all provide for some of the extra transistors, but certainly not all. There's something about these chips that Intel's not telling us, and 64-bit extensions is as good a guess as anything else.

"You mean once the OS and application developers have started using AMD's 64-bit extensions, Intel will come up with something to compete?"

No, he means that when x86-64bit support is there in software, Intel will have a CPU at the ready to support it. Since AMD's 64-bit extensions are the only game in town, and Microsoft has told Intel to go stuff a second set of x86-64bit extensions, Intel will be forced to either emulate AMD64 (a thoroughly bad idea), or include the instructions as the core of any 64-bit x86 CPU they release. Intel has already licensed the AMD64 technology, and thus will be forced to use its 'little brother's' technology to stay ahead of the curve. The interesting thing about that is that AMD can then choose the direction for future instruction sets. So long as the industry is working off AMD's instruction set, AMD calls all the shots.

Intel's big mistake was continuing to behave like a monopoly, and ignoring the breakout CPUs of its chief rival. Intel was banking on a 64-bit nosedive on x86, choosing to all but ignore the concept until it was too late. Intel knew that x86-64 would force Itanium into a small niche at the upper end, and would send 10+ years of R&D down the drain. Now, even HP is getting over its sunken Itanic - choosing to sell Opteron machines in order to remain conpetitive.

You can move data around fast if you have a good memory architecture. A wide data bus to external memory. And a bus clocked at high speed. And larger caches.

You can have all of that with both 32-bit and 64-bit processors. The 64-bittness doesn't help here.

Sort-of. There are four more addressing lines giving you up to 64GB, internally, the kernel can address up to 64TB virtual memory with segment/offset stuff, and of course the 64GB physical memory.
It's similar to the 8088/8086 with a 16 bit cpu, and 1MB of addressable RAM.

AMD Athlon Processor Build & Installation Guid by Futurepower(R) · 2004-02-16 01:56 · Score: 5, Informative

Haven't seen any problem with AMD processors. It's necessary to follow the Cooling Guidelines, of course.

Make sure you have a good power supply. We use KingWin 350 Watt supplies that have two fans. (Ignore the language, "Extreme Series". That's there just to appeal to gamers, who expect every product to include some reference to violence or games. There is nothing extreme about them, and they are reasonably priced.)

Note that power supply manufacturers sell power supplies that have 100 Watts more rated power for sometimes close to twice the price. That's to take advantage of the "more is better" people.

'sic' Latin for 'thus' - indicates error in quote by blorg · 2004-02-16 02:17 · Score: 4, Informative

Dictionary.com. It is used when quoting, to indicate that the transcriber has faithfully reproduced a possible mistake in the source. This is because it is considered bad form to modify a quote, at least without indication through square parantheses, which are generally used for explanatory additions due to loss of context, not corrections. And if 'sic' wasn't put in, it would likely look like an error on the transcriber's part. It's certainly not a /. thing ;-)

They don't have a bigger marketshare because even though the chips perform well, their construction hasn't (in the past) been up to that of Intel. Take, for example, the cooling required for AMD chips. Compare it to that of their pentium equivalents. When said cooling falls off (or stops working) - the pentiums don't burst into flames. That's the difference - higher manufacturing quality.

Modded +5 Insightful? Now that shows the weakness of the Slashdot moderation system...

Athlon, Athlon 64 and Opteron all have thermal protection, just like the P4s...and have had it for some time.

Further, current P4s dissipate more power than the AMD solutions, due to high clockspeeds that don't equate to better performance except for a slight edge in multimedia codec performance.

In short, at this point AMD is flat out better - and a much better deal to boot. You can pick up an Athlon 64 3000+ for about $210...that's a steal!

Burst into flames by dpilot · 2004-02-16 02:53 · Score: 3, Insightful

Bursting into flames has everything to do with one specific feature, and nothing to do with overall design quality. Specifically, the Pentia you're talking about has a fast-acting, sensitive temperature sensor connected to clock-throttling circuitry. When the chip gets too hot, the clocking is cut back to reduce power. FWIU, AMD has merely an on-chip temperature sensing diode.

AMD would do well to pick up Intel's design on this feature, but I'll bet it's patented.

But it is a single, specific feature. Other than that it's a very nice feature to have, it says *nothing* about other measures of quality in either CPU.

If you want to talk about other measures of quality, ask which CPU just plain runs well with today's compiler output, and which CPU requires new compiler generations in order to get decent performance.

Re:this isn't exactly correct.... by Slugworth01 · 2004-02-16 03:01 · Score: 5, Informative

Neither statement is exactly correct. The economics of semiconductor manufacturing are pretty complex. You typically have a certain set of variables to work with. You can invest in line yield, process quality, new processes, automation, capacity, marketing, new device design, retooling, and any number of other areas. You can build cheaper, less complex fabs, build in locations with cheaper labor rates or lower startup costs. You can outsource some or all your manufacturing to a foundry who can make your designs for a contracted price.

AMD has an approach that says they will "build smarter" than their competition. Their flagship fabs (Fab 30 in Dresden, for example) are highly automated with very tight process control, ensuring the right work gets done at the right time. The focus is on equipment utilization; reduction of tool idle time. Further, they focus on minimizing the number of non-product wafers in the line, which take tool time but don't directly produce any chips that can be sold. The management of all this is done through software.

They also have to focus on fab uptime ... since they don't necessarily have the back up manufacturing capability to allow them to recover if their fab is down. For example, AMD makes about two-thirds their revenue from processor sales according to a recent 10-Q filing. Most recent quarter for which there is data (for the period ending 12/28/2003) shows $1,205M in quarterly revenue. You can estimate around $800M in revenue from their processor lines. Fab 30 make nearly all their processors. If Fab 30 were to go down for one hour, that's one hour in the 730 hours in a quarter that they can't make chips. If they have demand that is greater than or equal to capacity, and they're running at full capacity, they would loose roughly $1M due to potential finished goods that could not be made. A cost of $1M per hour of fab down time is pretty typical in the market where AMD competes and for fabs that compare to Fab 30.

A single tool going down is a problem. The entire fab going down is a huge problem. Things that can bring an entire fab down include utilities (electricity, water, gasses, etc.) contamination of facility-wide services like vacuum line, DI water, and various gasses, labor strikes, natural disasters, fires, and plant-wide software.

When you rely on software to manage your manufacturing to the degree that AMD and other high-end semiconductor manufacturers do, you tend to pay a lot of attention to the software.

Oh no. by Carl+T · 2004-02-16 03:37 · Score: 3, Informative

Virtual memory is not the same thing as swapped out memory.
There are a couple of points here:

Even a 32-bit machine may have more than 4 GB of physical RAM, just as a 16-bit machine may have more than 64 kB. It's just that it cannot be mapped into a single block of virtual memory, so without ugly workarounds there's no way a process can address more than 4 GB.
It's not uncommon to (for various reasons) allocate more memory than needed, and never touch part of it. These allocations don't consume physical memory, but they dos count towards the 4 GB virtual memory limit for the process. Since the kernel must be able to produce the memory when asked for it, the amount of available swap space may decrease, but that doesn't mean that anything is actually written to the swap.

I don't know what bothers me more. People stating their uninformed opinion as fact, or people actually buying it and modding it up.

They make their profit on Xeons, where until recently they have had no competition.

Huh? Intel is the largest manufacturere of CPUs in the world. They have had a net income of about $1b per quarter for the last 4 quarters, they have $16b in the bank. Thier stock has remained pretty stable (aside from the .bomb inflation), etc.

Being that were I work (a university) and there are THOUSANDS of p3, p4, etc chips and way less than 100 zeons, if they are making all of their profits on those 100 chips that only cost a few dollars more than the other thousands of chips.... Whatever, obviously your wrong.

Take a look at what they're doing - they're going after Xeon - and trying to get a piece of the profit in a market that's consistent with their fab capacity.

They are going after the HPC market, because that is the only market for cheap 64bit CPUs. You don't need a 1.457THz 128bit processor to check passwords on your domain. Sorry all of you Windows admins, being a domain controller is not that big of a deal.

Crunching numbers across 20 processors for 5 days at a time is a big deal. Being able to do that in 2.5 days is a real big deal. Not being able to do that because you can't address more than 4Gigs of memory at a time is a show stopper.
