<strong>Considering that the new chip will have only one core, and less cache (i consider that they will remove the L3 cache and limit the L2 cache between 512 k and 1 MB) : i say 30 MB for the core, add 10 M transistor for the altivec, and 10 millions more for the cache : it make 50 millions of transistors, like the Programmer said the same amount of transistors that the last release of pentium 4. Considering that the derived chip, let's call him the power VMX is built on SOI 0,13 , it will make less heat thant the pentium 4 on 0,13 (but without SOI).
There is no reason why such a chip can't work in a Apple. Considering that the latter version of the tower have a more big (efficient ventilation) the power VMX will be perfect in it. </strong><hr></blockquote>
You should also consider that if this processor is likely to ship in mid-to-late '03 then it will likely be on the next process... i.e. 0.1 or 0.09 microns. This will allow far more than the Pentium4's level of transistors -- and you can add IBM's back of tricks into that... SOI, low-K dialectrics, copper, and a more stuff that I don't pretend to understand. I'd be surprised if this chip only
has a transistor count to match the current Pentium4. If it is really aimed at workstations and towers I suspect they'll beef up the heat sinks and go for it. With 8-way superscalar they'll probably have a huge number of execution units to back that up, big caches... and possibly even a multi-core version or two.
If you haven't seen it, go read <a href="http://www.tubbs.net/main.html
" target="_blank">this</a>. If you have read it, read it again. It says he's gone to work on VMX for IBM, but below that it says he is going to work on the Sony / Toshiba / IBM "Cell" project which is the next-gen PowerPC
. Yeah, its just a log of some guy and no its not iron-clad or for sure... but it makes a lot of sense and fits in with a bunch of other tidbits floating around (and I don't mean people spewing their unfounded opinions). IBM went 2-way multi-core with the POWER4... I don't think that's the farthest they're going to take the idea. You've got to do something with a billion transistors.
Hopefully this gives people a little confidence that maybe, just maybe, the future of the PowerPC looks pretty good. Mr. Jobs thinks so.
