IBM has already seeded the chip to developers. And they have a commitment to have the chips in mass production by Q3.

    ...Now these microinstructions execute at a rate directly proportional to the overall frequency of the machine

    This is *vastly* oversimplified - there are complexities to processor design & trade-offs to be made that make clock speed almost useless for the sake of comparisons between chips with different architectures - even if they DO perform the same number of instructions per cycle (which often isn't the case).

    there can be, and usually are, parrallel microrocessing units inside of each processor, so this can increase the operational speed

    And this is one of the differences between PowerPC and Intel architectures - in general PowerPC has chosen to sacrifice clock cycle speed to do more instructions per cycle while Intel has chosen to sacrifice the number of instructions to get more speed. In other words Intel usually chooses to do one thing at a time really fast while PowerPC chooses to do several things at once more slowly. Right there you have a *partial* explanation for the MHz (now GHz) gap.

    Fact: Intel chips have been extended to include all the same vector processing functionality included in most PowerPC chips.

    I'm no expert on this but most reviews & articles from fairly non-partisan sites have concluded that Altivec is superior to the Intel alternative and that this shows up in real world scenarios.

    The final upshot is that *in general* the PowerPC does more per cycle than an Intel chip. How much more (or even if it's more at all) depends on what exactly it's doing. But the fact remains: for most applications, especially multimedia applications that use Altivec, the PowerPC outperforms Intel chips of the same clock speed.

    BUT intel is so far ahead in speed that even taking the "MHz Myth" into account Intel is still far ahead of the PowerPC in overall performance. Apple has got to get it's old AIM partners to step up or it will have to abandon the PowerPC for Intel (or intel compatible)

    People keep on forgetting that Intel chips do a whole lot less with each clock cycle than PowerPC chips.

    Doesn't Linux run on both PowerPC and Intel hardware? Then why doesn't some enterprising individual go put together some various benchmarks comparing the two on this type of level playing field? I want to believe that the PowerPC is faster clock-for-clock, but I can't until I see some good benchmarks.

    I just google'ed for some and all that I could find were some ancient BYTEMARKS.

    It sure looks like it would be faster...

    >> the mantra was that CISC did more per cycle than RISC.

    The opposite is true: most of the RISC instructions execute in a single cycle, while many CISC instructions take much more, which is why raw clock speed is only perhaps meaningful for RISC chips and means very little for CISC, but totally meaningless across platforms.

    People keep forgetting that the G4 has a much higher raw clock speed than most of other very expensive high end RISC systems like Sun UltraSparc or SGI Mips or HP PA. How come other RISC vendors don't get blamed for their clock speed, while everyone screams at Apple everytime a faster system is introduced? Could this means that people just love to talk about Apple because it's cool and we all want a better Mac?

    I'm no expert on this but most reviews & articles from fairly non-partisan sites have concluded that Altivec is superior to the Intel alternative and that this shows up in real world scenarios.

    I've actually programmed both SSE and Altivec, and you're right in one way: Altivec is far easier to program, provides a much cleaner vector instruction set, and does more per cycle.

    The only problem is that it doesn't do TWICE as much per cycle in practice (save a couple of photoshop filters carefully selected by Apple), so the raw clock of x86 still makes Intel the winner in most cases.

    Intel have also worked hard on getting their compilers to automatically generate SSE/SSE2 code, which really improves performance on _all_ programs. There is no such thing for the PowerPC - if you want altivec you will have to handcode it. (And no, all the new altivec support in gcc is limited to the compiler supporting the altivec C language wrapper instructions - it will not generate them automatically).

    Motorola probably did the right thing FOR THEIR PRIMARY MARKET. Most PPC chips are doing signal processing in built-in systems where it is perfectly OK to handcode a filter for better performance/lower power consumption. The problem is that most general PC programs benefit more from Intel's approach which is more automatic.

    Finally - Apple/Motorola has a bigger problem: it makes sense to invest time in handcoding SSE/SSE2 for a CPU with 95% of the market, but usually not for one with 5% of the market.

    For those of you who have not read ALL of the CPU articles at ArsTechnica. Go there now and do so. Before posting any of your inane babble about clock speed and processor power.

    It IS true that Motorola has fallen behind Intel - sort of.

    There are other advantages to hardware other then Intel based systems.

    Since this is an Apple thread I'll focus there - One of the most note worthy (My opinion) Is apple's System controller.

    Go READ the articles at ArsTechnica!

    Rather than re-writing I'll simply cut & paste.

    Fast system controller: The system controller, first introduced in Apple?s highly-regarded Xserve line, coordinates and transfers data and instructions among the processor(s), PCI bus, memory, graphics and I/O buses of the Power Mac G4. Controller speeds in the new Power Mac G4 configurations run as high as 167MHz.

    The PCI bus is what really impressed me.

    Direct PCI bus: In another example of superior architecture, the Power Mac G4 optimizes PCI performance by connecting the PCI bus directly to the system controller. In a typical PC architecture, PCI devices connect to the I/O controller through a bridge, a bottleneck in the data path where all connected PCI devices are slowed down to avoid overloading the system controller. Going through this bridge constrains PCI throughput to 133Mbps (the bus speed on Pentium 4 systems), even with otherwise fast PCI devices. This slowdown of data to and from PCI devices results in greater overall system latency. The Power Mac G4, on the other hand, features a direct 266-MBps bus to the PCI slots to guarantee high throughput and low congestion ? in effect, lowering latency. The Power Mac G4 also supports write combining, which allows write instructions to be grouped into one large instruction, further increasing data throughput.

    Then Apple oficially slams PC architecture.

    On the Power Mac G4, FireWire, Gigabit Ethernet and even the ATA/100 bus are built into the system and integrated directly into the system controller. (The ATA/66 bus has its own controller.) This dedicated connection reduces PCI congestion and guarantees low latency, resulting in optimal FireWire, Ethernet and hard drive performance. And as a side benefit, it also keeps the computer?s PCI slots free for your specialized audio and video cards instead of using them to provide basic technologies.

    I got this info here.

    Apple is not the end all - be all of systems. Two of the greated systems are made by DEC & H/P. The UltraSparc kicks the crap out of anything Motorola & Intel have to offer.

    And let's not forget the Alpha. The Pentium - Pentium III architectures were based on technology stolen from DEC. Technology that Intel is still paying for today.

    It basically falls down to system preference. Mac users DO NOT CARE if you can build a PC for $400. Mac users DO NOT CARE if only a few of the best selling game titles are ported to the system.

    Having more game titles available is a Good Thing - naturally -but I find myself being... PRODUCTIVE instead of having my time eaten away by games - Linux users also what I'm talking about - unless they've downloaded BZFlag or Crack Attack.

    You know, the 1.25GHz macs were never overclocked. Take off the heat sink and see "7455A 1250" on the chips. This rumor started to spread after Motorola didn't update their G4 specs to include 1250MHz availability. The likely explanation is that these parts are only available to Apple.
