Next Generation G5+ 975, 976, or 980
This is the all encompassing thread for the next generation of G5, the G5+ if you will...
If I could summarize some information that has dribbled down the pipeline in the past year:
-Speed increases up to 50% for the same clock rate.
-Hyper Threading capability
-Onboard memory controller
The word is that the 970 was designed at the tail end of the POWER 4 series, and the original 970 chip was fast-tracked for delivery.
This next gen G5 (975, 976, 980 - whichever its name) was designed concurrently with the POWER 5, and will be ready for production soon after the POWER 5 introduction beginning at 3gHz.
Any thoughts, information, or further discussion?

Yes, the first PPC's based on the Power5 will start shipping in the second half of this year.
Now, where this comes from?
"The upcoming 9XX IBM PowerPC processor, that will likely be based largely on the Power5, will raise the power use per Ghz over the 970fx. That's due to a likely larger L2 cache and a feature similiar to Intel's Hyperthreading causing the chip to utilize on average more of the chips resources at any one time.
But don't expect much higher frequency rate on the next 9XX chip after the 970fx, IBM focused on using the available resources more efficiently rather boosting the clock rate."

It seems the G5+ will further down the road go dual-core.
"AFAIK GPUL2 (PPC975?) development was much closer to POWER 5
development, POWER 5 systems have been up and running since
February 2003. A year on POWER 5 is ready to rock and roll. I believe
GPUL2 is not far from launch and that there is the possibility that
Apple will forego a revision of the G5 Power Mac in order to ship the G6,
if they choose to call it that, on schedule. This may also relate to
DDR2 and PCI-Express adoption, GPUs for PCI-Express are ready
to go soon. One thing that has puzzled me for a long while is seeing
VMX mentioned in relation to POWER 5 supers but having no sign
of it yet."

"One thing that has puzzled me for a long while is seeing

That is because the POWER series has not had it, but the PowerPC (970 included) have VMX/SIMD. I am guessing the 980 or whatever the POWER5 little-brother is called will.
tied to the PowerPC 975, apparently. IBM has plans to release a compact system board that Apple will use to power a super-compact version of the Cube with an aluminum enclosure, 100% passive cooling, and three full-size expansion slots (PCI Express, two PCI-X 266).
THIS is stupid... THREE slots in a cube? IBM making the motherboard? WTF are MOSR smoking???
Oh... And a re-release of the cube on top..

The same thing they've been smoking for years. The same thing they were smoking when they got into their car crash. The same thing they are smoking all day, every day looking at the flashy flash ads their site is now littered with.
Gosh, people should really learn to listen to nothing on April fools..
Correct me if I'm wrong, but is Power5 a whole heap of processors in one ceramic base? Or does it just look like eight processors on a ceramic base..
What is the big deal about it. I read the site, but I got a little overwhelmed.. Anyone know how to simplify what is is and what's so good about it?
Thanks!

POWER5 has four cores and some massive caches, if I am not mistaken. I think this is what you see in the image.

I've been reading MOSR for about 7 years now... But this has to be the most stupid rumor they've ever posted..
"The chip family's future goes something like this. IBM will follow the current G5, the PowerPC 970 with the 980, based on the Power 5. The 980, says the source, will be chip that delivers Steve Jobs' promise of a 3GHz Power Mac this time next year. The part will kick off at 2.6-3GHz and max out at 4.5-5GHz. By comparison, the 970 will peak at 2.8GHz.
The 980 will include Simultaneous Multi-threading (SMT), which the source claims provides a 30 per cent performance gain over Intel's implementation SMT, called HyperThreading. The 980 will also feature IBM's eLiza fault-tolerance technology. Greater parallelism will be provided by extra computational units: one more AltiVec, two more floating point units, and two more integer units."

Whoo hoo!! The next lineup of Macs is going to kick some major ass.. Assuming that combining the dual processors = the GHz value. (i.e, dual 2.0Ghz = 4Ghz) And there's no real reason why it shouldn't (is there?)..
edit: We would be almost at 10GHz then! Dual 4.5 = 9GHz!!
What's after Gigahertz? it it Terahertz?
Ohhh.. Dual 4.5GHz.. :drool:
I'm such a geek...
I've heard before that this isn't the case however, that having two processors isn't the equivalent of just adding their power together.. But it kind of makes logical sense if you think about it..

True, a dual 2.0 isn't the same thing as a 4ghz, but it's close, some would say ~the same as a 3.6ish. So a dual 4.5 would not be 9ghz, probably closer to 7.5-8. The system bandwidth has to keep up too

We need a little more then just a few Hz to hit a Terahertz... Try 1000 Gigahertz = 1 Terahertz
Me so stupid! lol
I thought there was something strange about my calculations...
I therefore edited my last post.. Muhahahah..
