That's because even with SOI, new Altivec, a G4 is a G4.Originally posted by Sol
...Apple has so far resisted re-branding any of Motorola's chips a G5, even with new technologies like Silicon On Insulator, more AltiVec units, etc...

Yeah, but what an embarrasing "G5" that would have been.

It is inconcievable to me that IBM would in fact claim that they do not intend to support the AtiVec unit in Linux userspace (at least) when in fact they would have to go out of there way to not support it, for no apparent benefit. On certain tasks AltiVec is unmatched and I'm sure that IBM knows that, and I'm sure that many prospective customers know that.
Like I said, I think this rumor is a fabrication, and I think the AlitVec chit-chat was thrown in to provide some meat and some excitement (purpose-built feature for Apple, etc).
hehe, fabrication..... I hope I'm not the only person that caughtLike I said, I think this rumor is a fabrication
And I pretty much agree, just I think this particular rumor is bunk.Perhaps. I do generally come down on the side of skepticism, but the body of evidence out there is beginning to make it look like the 970 could be coming out pretty soon (say, within the next 6 months). And I would certainly be shocked if Apple chose not to use it. Well, we'll see soon enough (or not soon enough, depending on how patient you're feeling!).
Slight to major change, PowerBooks used to use a PowerMac chipset -- now bumped in favor of the iMac single chip version.Originally posted by ddtlm

Hmmm, I was under the impression that the system controller was pretty much the same one used in all DDR Macs, and if that is the case, then there is nothing to worry about cause its been spread around all over all ready.
Yeah the PMac DDR chipset is single-chip too as far as I know. I'm under the impression that all of the Mac DDR system controllers are essentially the same chip.Slight to major change, PowerBooks used to use a PowerMac chipset -- now bumped in favor of the iMac single chip version.

Well I certainly wouldn't claim that they are wrong. 🙂Unless Apple is wrong there are two different DDR chipsets currently being used.

I think ... that because the processors are PowerPC, They should change to P5 !
I'll duck now 😀

Strange to put in a vector unit and then not make use of it in their machines, even if it's just an available library and compile time option -- it would speed up those apps that can make use of the code.
If Linux is going to be extended to include Altivec and IBM is shipping Linux boxes, there seems to be a disconnect in the information here.
Might not quite fit in with their compile once and run on a bunch of boxes strategy, but some people do end up tweaking code to cut run time at the expense of portability.
That must have been a really quick search.. try yellow dog linuxOriginally posted by jettredmont
Umm, no.
A quick search for "linux altivec" on Google didn't turn up anything more recent except for a note from a developer working on Linux-PPC64's Altivec support late last year which indicated Altivec support was being developed but not quite "there" yet.
As I said before, IBM is not likely to be shipping the cutting-edge developer build of Linux on their blades. If Altivec support isn't time-proven yet, it likely will not make it into the IBM Linux-PPC distribution when it ships.
Do you have any more recent link indicating that Altivec support is in place and working?
http://linuxppc64.org/In the middle of year 2000 an effort was started at IBM in Rochester MN to create a new Linux port for ppc64. This new port would be a high performance, scaleable version of the Linux kernel to run on 64-bit PowerPC processors.
