AMD/ATI Working On CnGPU

Unfortunately the article has very little info or resources to back it up. But it's one of those things that make you go "hmmm".

Interesting. Now lets see CPU GPU Phsyics and AI on one die. 🙂

Seriously though-- will a cnGPU utilize system RAM as video RAM or what?

If the CPU is on the video card itself then I would say it would be using vRAM. Even though vRAM would likely be outdated by then.

Wow, that's the poorest excuse for an article that I've ever in my life read. And if they were to try to utilize system RAM, it wouldn't be worth doing, because of the latencies involved (kind of like how they had to start putting the L2 cache directly on-die, because of the latency involved with it being on the motherboard). I'm sure they'll just put an extra 512 MB of DDR3 on the video card, specifically for the CnGPU. I guess this means that Physyx (or however it's spelled) cards won't be catching on after all.

I think this is for the mobile market rather than the gamer crowd.

and budget buyers

The idea of joining both a CPU and a GPU in one chip has always been there but the technology was not available. Now, with most CPUs made on 65 nanometre and GPUS also moving to 65 from 80 and with 45 nanometre looming in the horizon, the time is right for just such a venture.

end of question.
author is a noob

Well, this isnt really so surprising - AMD/Ati have been hinting at this ever since the merger. I'd be interested in seeing just how well this plays out, especially compared to discrete video cards. Shocking news would be if a year from now I saw a high end gpu and a cpu combined in one socket.

It would probably be purely oem parts. By that point the system ram will be ddr3 and the graphics would share system memory, much like the integrated intel chipsets now

I can see this working for the mobile market or the budget systems but not for the high performance ones. Seriously, who wants the heat of their X1900 series GPU on the same cooler as their X2 or C2D? Not me. But for the mobile/lower power market it could be perfect, one chip and one cooler instead of 2 different chips and 2 cooling systems. It would be a space saver. Of course I'm talking about those portable ones, not beast laptops like the XPS or whatever 😉

This "article" is just some speculation and rumour.
Obviously ATI and AMD are working on this (it's been in many press conferences since the merger) and many other things together...the speculations are:

1. A multi-GPU coprocessor that drops into a CPU or HTX slot. This would have it's own system Ram of 4 slots (up to 8GB+) which could be used by the rest of the system as well (each CPU socket on AMD designed boards gets 4 Ram slots).
2. A CPU with an on-board GPU (possibly multiple GPUs)...this would be great for mobile, but less so for desktops (except for the latency savings).
3. A GPU/Physx (or other) combination coprocesser for second CPU sockets.

The whole point is that Torrenza (AMD's new open cHT modular architecture) opens up combinations and enhancements that nobody has even thought of yet.

At the end of the day though, for the higher end and more exotic stuff we are talking about at least a year from now (though single coprocessers for CPU sockets are already selling in the server industry). Certainly on-board CPU graphics is a 2008 (at least) discussion...
