    Myth: RISC is better than CISC

    Take a look at those benchmarks I posted earlier. Now sort out the RISC and CISC machines.

    What's that? They are ALL RISC based cores, bar the Pentium I?

    The fact that Intel (the maker of the Worlds most successful "CISC" CPU's) has moved essentially to a RISC core (to exploit the easy pipelining benefits) with a CISC "frontend" (for legacy compatibility) starting with the Pentium Pro, kinda shows that RISC is better than CISC, don't you think?

    CISC can theoretically do more per clock cycle than RISC.

    Prove it.

    If you said, "CISC can theoretically do more per instruction than RISC" and left it at that, I wouldn't be arguing with you.

    When we hit a performance ceiling due to minimum transistor size, we will have to exploit pipelining and multiple cores to the fullest and the easiest way to do that is to embrace RISC (due to predictable, uniform instruction lengths) as the better choice over CISC.

    Lastly, I am supplying some information to people who know very little on the subject.

    I thanked you didn't I?

    If you want to write up a CPU Design FAQ for dummies, have at it.

    I don't design CPU's, though I have been designing digital devices since the late 80's.

    Furthermore, the CISC architecture is designed in a way where more work is theoretically done per instruction.

    Careful wording there, impressive. More work per instruction. Well that is the basis of CISC. But whether this is an improvement over RISC is hard to quantify, with individual implementations of both giving differing results that cannot say one is better than the other overall. These CISC instructions that do more work, also require more clock ticks to complete. But then RISC instructions, which usually take only a single clock tick to complete, usually need to be combined to do the same work as a single CISC instruction. The P4 though, does some impressive magic with CISC->RISC processing that blurs the traditional concepts.

    But how about work per clock tick, which is what matters if we're talking about the MHz myth...

    Here http://www.swox.com/gmp/gmp-speed.html are PowerPC's doing MUCH more work per clock tick than a Pentium 4. Seemingly many times (3.4?) more.

    Hell even the old 603e seems to be substantially faster than the P4 per clock tick, in these tests.

    BTW, the Itanium 2 would appear to be a rocket!

    VCD encoding, G4 doing more per clock tick than an Athlon http://klicman.org/altivec/

    I'm not saying a current model G4 is faster than a current model x86 based machine, BTW. But if the PowerPC 970 can get close to the clock rate of the P4 (or then P5), we might see "G5's" running "P5's" into the ground.

    PS, I have an old 300MHz G3 iBook, after about 15 years of x86 (currently have P3-500 amongst my currently 16 something PC's). I'm not a zealot of either, but I hold high hopes for the 970.

    OK, I'm tired of all this stupidity about how nobody knows exactly what MHz means, and how its not really a measure of speed.

    MHz is NOT an absolute measure of processor power.

    Looking at my old Borland TASM x86 instruction breakdown book, I see each instruction with required number of clock ticks to complete (some variable). The same instruction is often done in less clock ticks on a i486 than on an i386 for example, meaning that a 100MHz i486 is usually faster than a 100MHz i386.

    Therefore MHz is NOT a comparative measure (of CPU power) between a 486 and a 386, and they are so closely related (a 486 is not just a 386 with an integrated FPU). The difference between different CPU architectures is often HUGE.

    The PPC IS usually faster per clock tick, than ANY x86 based CPU and when the Altivec shines it is blinding.

    This must be one of the most ridiculous things I have ever heard in my entire life.

    The Navy, as I KNOW it, employs only technologies that are required to get a job done properly, nothing more and nothing less. Often, this means developing technologies in-house, at PCB level and beyond if need be. When I worked for them in the 80's, their technologies were approximately 10-20 years ahead of commercially available technologies.

    If they were going to do something so unbeleivably STUPID as having radio control over a destroyer (worlds most powerful crypto or not), there's not a snowballs chance in hell that they're going with 802.11b.
