IBM To Add Silicon-On-Insulator (SOI) To PowerPC

    From the ZDNet article:

    SOI can be used in one of two ways. It can be used to create low-power chips. In this case, by keeping clock speed the same, SOI would reduce the power consumption of a chip by two to three times.

    Apple already claims >5 hour battery life for Powerbooks. With a 2 to 3 times power consumption decrease for the processor, how much more battery life can they get?

    Yeah, sure, it's nifty to do graphics/desktop publishing, but if you're serious about that, you're running an Amiga or BeOS anyway.

    The Mac decimates both the Amiga and BeOS in the graphics and desktop publishing arena's. The Amiga used to be (and still is somewhat) a wonderous machine to work with video with, but it's been floundering the past several years due to not really having an owner that's been willing to pour money into it. The BeOS, yes, has a more elegant architecture, but alas, it lacks color management, postscript font support, and applications from Quark, Adobe, and Macromedia. Until it gets more apps, the BeOS will remain an oddity to everyone except it's core users.

    With Apple shipping nearly a million iMacs and G3/G4's per quarter and with Power PC chips selling for (a complete stab in the dark) $250 a piece, that translates to a BILLION dollars a year of business for IBM and Motorolla. If you ran a company, would you turn down that much money?

    AMD's Athlon and Intel's Wilamette are excellent x86 designs, which are severely cutting-edge. I'm not sure about the Willamette architecture, as I haven't done much reading into it, but pretty much everything from the Pentium (P6 in particular) onwards has strayed from being pure x86 in favour of a heavily pipelined architecture. In the case of the Athlon, effectively the CISC x86 instructions are emulated by splitting them down into what AMD terms MacroOps, and letting the RISC core deal with the rest.

    Where the PPC scores here is that it is fundametally RISC by nature, although IIRC the PPC has a basic 68k emulation frontend for legacy purposes. However most modern apps on the Mac are tailored for the PPC, and as such, can use some of the funky RISC features to gain a speed advantage. For example, some Photoshop filters will render quicker on a G4@400MHz than on an equivalent, or higher spec x86 box, simply because the architecture is less cluttered, and the compilers don't have to take the legacy baggage into consideration. The same applies to the Alpha, in that by using MHz as a speed comparison between architectures, you are doing the more modern chips a major disservice, because they don't need to be clocked as high to gain comparable application performance.

    As for the colour and font handling, he's right. The Macintosh's ease of use made it a very strong contender in the DTP arena early on, and as a result, programs like ATM and ColorSync allow a far greater degree of output control than the Windows (or Linux, sorry guys) equivalent. This is just by the nature of having existed on the platform longer, however.

I don't remember if the chip was designed by Motorola or IBM, but that should have been great technology released to the public.

Maybe Intel threatened IBM's supply of Pentiums and the emulation wasn't good enough for IBM to tell Intel to take a hike. Or maybe they didn't think it would sell well. Or it didn't work at all. Or maybe it was only a rumor.

    It is really a shame that the PowerPC G4 is currently only at 500 MHz. RISC processors should easily have a MHz advantage because they are simpler in design. Man, imagine a 1 GHz PowerPC G4 available today. People would definitely notice.

    IBM demonstrated a 1.1 GHz PowerPC a year ago at (IIRC) HotChips '99. Current rumor is that IBM is ready, able and willing to ship G4s at 780 MHz but has business reasons for not doing so.

Neither company is capable of shipping large quantities of their highest-rated chips. In the absence of the PIII/Athlon rivalry, PCs today would be topping out at about 700 MHz, and they'd be comparable to today's top PowerPCs.

    This stops some of the charged layer from forming as the charge cannot move (easily) in the oxide. Which speeds up the transistor.

Since IBM is using SIMOX wafers, this means that they have one heck of a good ion-implanter with amazing straggle control.

      Judging from the cross-section SEM images at IBM's website, their SOI layer is of similar thickness, so there is still a bit of silicon between the source/drain regions and the oxide. This distance is what allows them to use the SIMOX wafers, handling the straggle from the ion implantation.

Though there are some major differences between the G4 Apple uses and the chips IBM, if Darwin can run on x86 I am sure it can run IBM's PPC. Perhaps this (the opening of Darwin) could lead to the begining of the fruits of IBM's relations with Apple from the 90's. Darwin as an alternative *nix-like os for IBM servers? Drive-less iMacs net booting from Big Blue's Big Iron? SOI for everyone?! -PSM
