IBM's New Processors To Exceed 5Ghz

Jordin Normisky writes to mention the news, via ZDNet Asia, that IBM's new Power6 processor will be unveiled next month at a conference in San Francisco. They're also planning to announce a second-generation Cell, both of which are expected to run faster than 5GHz. From the article: "In addition, the [Power6] chip 'consumes under 100 watts in power-sensitive applications,' a power range comparable to mainstream 95-watt AMD Opteron chips and 80-watt Intel Xeon chips. Power6 has 700 million transistors and measures 341 square millimeters, according to the program. The smaller that a chip's surface area is, the more that can be carved out of a single silicon wafer, reducing per-chip manufacturing costs and therefore making a computer more competitive. Power6, like the second-generation Cell, is built with a manufacturing process with 65-nanometer circuitry elements, letting more electronics be squeezed onto a given surface area. "

      Converting back and forth continuously causes hardware and firmware people problems. Almost all protocols, and the embedded processors on adapters are big endian. At least in English with arabic numerals, when you write a number in hex on a piece of paper it is big endian. When you look at a big endian memory dump, it will match what is on the paper. When you look at a little endian memory dump, there's an extra, unneeded layer of complexity. You have to do the conversion on a per field basis. When 2 and 4 byte fields are mixed, it can be a PITA. So I think we should have stuck with everything being big endian.

      3) IBM did not produce any material stating that they were going to make 3GHz Apple-style PPC chips either before, during, or indeed after Jobs' claim. It is thus something he, rather than they, said.

      My theory is that Jobs said this with IBM there to try and put them in an awkward position in the hope that they would then do what he wanted to avoid looking stupid. When it didn't work, he was the one who ended up looking stupid, so he threw one of his famous hissy-fits, gave IBM a piece of his mind, and got told in no uncertain terms that Apple's wants and needs would be given the priority that their 4% consumption figures warranted, which meant they'd get their higher clock speeds some time after the rest of the POWER line did, and to please refrain from making promises on IBM's behalf in the future, thanks for your call Steve, have a nice day.

      NB: I have nothing against Steve Jobs' habit of stretching the truth now and again -- he is after all primarily a marketer (and a very able one at that), and good marketers tell customers what they want to hear, and that sometimes involves bending facts to fit in with whatever version of reality they're trying to sell today.

      Basically they take a tiny wafer-thin piece of silicon, use chemical to scrape out millions of little transistor shapes onto its surface, and strap a buckin' bronco of a clock crystal on it that shakes it like a salt shaker, or like jello jigglers on free-based cocaine.

      Thusly, the outrageous oscillating action of Mr. crystal causes the tiny transistorized citizens to go into a tizzy, but they're all right because they're not hollow and fragile like vacuum tubes, so they get all busy and start swinging their logic gates open and shut kind of like an electron square dance.

      The speed that the crystal is eventually set at is the maximum speed at which the transistors can go about their daily lives, such as munching on electrons and crapping them out, organising meetings, forming PTA (parent-transistor association) clubs, and dipping into the cache without generally spontaneously combusting or reverting back to silicon amoebas. Each time the crystal wiggles its booty constitutes one clock cycle, and the number of operations per cycle varies based on the processor and the types of instructions the poor transistors must labor over.

      Clock speed has been historically limited by various things, including level 2 cache memory timings (remember this stuff has been running at CPU speed for about 5 years now!), motherboard design, pipeline depth, heat dissipation, ALU and/or FPU limitations, or even the leakage the P4 was subject to at 4GHz+ clockspeeds.

      A clock cycle is the flipping of the voltage of a clock wire from 0V to Vcc (originally 5V, but more like 1.6Volts these days). This clock signal is used by almost every transistor in the computer to coordinate the transitioning of signals from one stage of pipeline of operatins to the next. It is possible to not use a clock (asynchronous compuation) by making each stage generatr "Im done signals" directly between stages, but this is significantly more complex - you have to take ito account wire length and the load levels. Conversely, on each and every clock tick, the computer designer can be guaranteed that every memory cell has been sucessfully written to, and can thus design circuitry that begins reading the values of those memory cells immediately at he voltage flip. While you might not see the distinction, consider that two unrelated people in two different departments are deigning the different pieces that talk to each other - much like software development. Te clock becomes a religeous standard.

      Thus, hopefully you can already see that while clock is critcal, it does not necessarily relate to performance. You still have to design all the ciruitry that performs the operations between those clock ticks. Almost every useful operation (such as adding two numbers) requires many many clock ticks. Modern computers are designed to maximize the concurancy of operation so that while it takes many clock ticks to do one macroscopic operation, so many operations are being processed, that on average, you get more than one macro operation completed per clock tick. You can have as may as 80 high level instructions simultaneously "in flight" throughout the pipeline.

      The challenge is largely mathmatical / logical. If all you wanted to do was add up two sets of numbers with arbitrarily large set size, then you could create an infinitely fast computer for not that much money. (incidently, if you just wanted to perform the logical ANd or logical OR, yo could do it for mere pennys and ultra high performance - peta flops and beyond). But such trivial situations are almost completely useless. All real data is dependant on previous calculations. A = B + C / D. You cant simultaneously add and devide, you have to do one then the other. In an identical maner MOST computational operations are 1 or two instructions away from some dependent calculations (such as adding being dependent on the loading of a number from slow memory).

      So in the mid 90's we saw a surgance in CPUs that could intelligently find every concievable independent operation that can be found in a given command sequence. The greater the parallelism, the faster the average macro-level operation per second (such as SPECint or SPECfp).

      One trick, however is to compile from source code the order of operations that maximizes data independence. MMX, 3DNow, SSE, Altivec are such successful examples. Intel failed in its attempt to completely rewrite an instruction sequence in its Itanium using state of the art concepts. The end result was GREAT at SPECint and even better at SPECfp, but failed miserably at normal real world applications. To say nothing of the 800MHZ clock speed (in the day of 3GHZ monsters). Again, the clock represents the fastest rate at which a single micro-operation can be completed (such as moving a number from a high performance buffer to the entry-way of an addition pipeline, or from the output of said pipeline back to a meory cell). But the Itanium chose to do some VERY complex things in each and every clock tick (like renaming 128 registers in a sliding window to support a function call stack). This meant that to comply with the rule that everything gets done by the end of the clock tick you can not increase the clock speed until you speed up the slowest operation.

      The Pentim 4 is the exact opposite. In a marketing attempt to advertise 4GHZ CPUs, the took simple operations and broke even them up into multiple stages such that the worst case was 1 / 4,000,000,000 of second in duration. Further, th

In particular products, a single processor may be able to host 2-300 virtual instances, although theoretically up to 1024 VMs are possible. Memory partitioning and migration have been added as well, which reduces system down time for repairs.

    Yeah, they'd have taken a hit for 6 months, especially in the laptop arena. I was still sitting on a 1 Ghz G4 Powerbook, because replacing the machine for a 1.42 Ghz G4 Powerbook seemed like a pointless upgrade. It didn't look like a low power G5 (or 2 Ghz G4) was in the works, and Apple would have had an AWFUL 1H2006. However, there was an expectation of a week 1H2006 because of the transition.

    I think that the long term edge of having ALL software running on x86-64 instead of x86-32 would have given them a performance edge over Windows for 3-5 years, and should have been considered. Supporting 32 and 64 bit PPC is different, they don't. They support PPC-32, with some libraries for mathematical software in PPC-64. The core OS is PPC-32, and that will never change.

    I think that making the OS, and all apps x86-64 would be nice.

    Higher clockspeed is a VERY good thing. While parallel execution units/multiple cores is nice for doing several things at once, sometime you just want the single application you are using to get done faster. So you can either run the clock faster or make it accomplish more per clock tick.
    I gues maybe if they had a gazillion parallel cores or execution pipelines they could try to guess the most likely actions you are going to ask the CPU to do before you actaully ask it and calculate the reults and then guess the next one after that, etc (kind of like calculating every possible move and counter move in a chess game), but I don't think we'll have enough parallel processing capacity to do that very "deep" for a while (although I think most modern CPU's do a little bit of predictive work, but nothing on that scale.)
    I personally think Netburst was a very good idea (optimize the CPU to make it easier to clock to "ludicrous speed"), but they simply ran into some unexepcted barriers and had to go back to a different architecture until they figured a way past those issues. Maybe the next Intel (core 3?) architecture can incorporate all the cool features that let core 2 do more per clock AND see significant clock speed increases.

      As a HUGE fan of the G3 and G4 processors (especially during their respetive haydays) I can only say I'm not sad that both of my new Macs have Intel processors (1.83 Core Duo, and 2.33 Core 2 Duo, repsectively). The nice thing about these chips are they are an obivious performance jump for portables, and the transition thus far has been flawless for me. Even if IBM made the 5GHz processor work in a Mac, I'm not sure it would persuade me, since I can now run Windows and Mac OS on my computers. This flexibility is more important to me than sheer clockspeeds. Maybe more PC people will start being like many Mac users have been for the past 20 years and start realizing that cpu speed isn't everything (Apple marketing aside, or course). It is pretty clear, that given an unbiased chip speed test, the G3-G5 chips consistently out performed anything by Intel. Now that IBM is out of the Mac market, I think it is funny that the PC crowd is finally acknowledging what has been true all theses years; the PowerPC architecture was superior in nearly every way. But now it is all irrelevant, I suppose. But at least now that my PC friends accept me as an Intel-lovin' PC user (albeit it on Apple hardware), I can at least say: nanner nanner boo boo, I told you so! I'll never sell my G4 by the way, so no more offers!

      "Perhaps IBM is trying to win back Apple with this announcement?"

      I'm far from convinced that it was Apple who dropped PPC rather than IBM deciding that Apple's demanding and difficult nature together with their ownership of significant portions of PPC IP simply wasn't worth the hassle for the relatively small number of chips they consumed. Lest we forget, IBM pulled off a major coup by getting all three games console manufacturers to use their chips, including Microsoft, whose prior XBox offering was as solidly planted in the Intel world as their PC software offerings. This was announced shortly after Apple's change to Intel, but the fact that consoles are integrated consumer electronics items means that negotiations must have been going on for quite some time before-hand, because the choice of CPU has a radical effect on the design of the rest of the hardware, the system software and firmware, compatibility with existing stuff for prior consoles, and a host of other factors that mean it isn't something manufacturers do on the spur of the moment (well, except for Nintendo, whose use of a PPC in their GameCube made using one for the Wii pretty much a no-brainer). MS and Sony in particular must have been given some pretty convincing presentations fairly early in the design cycle for them to select that CPUs they eventually used, so it's pretty much a certainty that negotiations were going on quite a long time before Apple announced that they would now be selling what amount to PC-compatibles in pretty boxes after two decades of mocking them.

      So despite the fact that Apple spun things to make it look like this was a choice they made, Apple's prior record on spin would suggest that we not blindly believe them, but instead consider what the situation looked like from IBMs' perspective:

      1) Apple were constantly pushing for options that weren't necessarily in line with IBM's goals as a manufacturer of CPUs, the vast bulk if which were sold for embedded systems and large servers rather than desktops and laptops.

      2) The presence of Apple IP in the PPC line meant that IBM couldn't sell them to others without Apple's permission, and would probably need to pay (perhaps significant) royalties if that permission could be obtained, which is far from being certain given Jobs' antagonism to anybody making what might turn out to be a potential Mac clone.

      3) Despite Apple implying that IBM couldn't make chips with clocks above 2.X GHz, they seemed to have absolutely no problem producing ones with multiple cores that run at 3.2GHz for Microsoft and Sony in volumes and at prices that were attractive consumer electronics manufacturers who are hoping to sell hundreds of millions of units during a product's life-cycle. What then is more likely: that (as Apple claim) IBM couldn't manufacture chips at high clock rates despite amply demonstrating their ability to do so, or that IBM were not willing to dedicate large amounts of time and effort on a version of the Power architecture that they could only sell to a customer who accounted for at best 4% of their output (and that 4% was prior to the deals that made with MS and Sony, so it would have ended up being a lot less than 4% a couple of years down the line)?

      4) Apple also wanted extremely low-power G5 chips for laptops, which wasn't something the other 96% of IBM's market were demanding. They would thus have to devote considerable amounts of R&D to a project that was only of interest to one minor (in overall production terms) customer instead of using those resources to improve products and the processes that manufacture them which were selling in far larger numbers.

      With the above in mind, it is IMO far more likely that IBM told Apple to sod off rather than the other way around, just as any company would when faced with a choice between dedicating research, design, and manufacturing capacity to satisfy the whims of one small, difficult, and tempestuous customer, or using them to satisfy the requirements of others who are much larger, more profitable, and easier to work with.

  51. It's both; neither. by Kadin2048 · · Score: 1

    My understanding is that the current-generation "CISC" chips have a preprocessor (on the die) that turns some of the more complex instructions into several less complex ones, which are what the processor's logic pipelines work on. Thus while the compiler might still produce CISC microcode, it's really being cross-compiled one further time before it's actually executed. So you can sort of argue it either way. The processor as a unit does execute more instructions than RISC chips; but in a way they're not executing them natively.

    The main reason I've heard why CISC+preprocessor designs won out over pure RISC is because the die area required for the CISC-to-RISC pre-processor shrunk steadily as new manufacturing processes were developed. The logic required to translate CISC to RISC is basically fixed, and as you go to smaller and smaller processes, it represents a smaller and smaller portion of the total processor die area. Thus, every year the advantage of RISC over CISC shrinks. It's sort of an unintended consequence of Moore's law: the ability to pack more transistors onto a die has also made radical changes to the architecture's less attractive, since it makes preprocessor logic "cheaper" in terms of die space.

    The x86 instruction set has become the lingua franca of processors, even though most of them immediately break those x86 instructions down into RISC-ish sub-instructions for actual processing. Whether you can still call this hybrid architecture CISC or RISC is mostly semantics; it's a little of both.
