i know how ridiculous the title sounds but check out this article on direct x 11:
http://legitreviews.com/article/1001/1/
and in particular this paragraph:
between directx compute and opencl:One of the key new features of DirectX 11 is support for DirectX Compute, which enables developers to utilize the massive parallel processing power of modern GPUs to accelerate a much wider range of applications that were previously only executable on CPUs. Accessed via programs called Compute Shaders that are executed on the GPU, they can be used to enable new graphical techniques (such as order independent transparency, ray tracing, and advanced post-processing effects), or to accelerate a wide variety of non-graphics applications (such as video transcoding, video upscaling, game physics simulation, and artificial intelligence).

i don't see the forced cpu upgrade cycle surviving much longer, no more having to buy new ram and a new motherboard because the new generation of cpu's use a different socket and a different memory controller, no need to reinstall the OS after a motherboard/cpu upgrade, no need to overclock a cpu to try and get maximum performance out of your configuration, just buy a faster video card, install the new drivers and bam!, you're done.
i wonder how long before someone custom creates a linux distro using cuda?[/list][/url]

And the graphics card manufactures have a stellar record regarding bug-free drivers.

Not in our lifetime. GPU is limited to very limited tasks and I don't see programmers changing entire code bases to adapt. (How many years has it taken even to get limited multithreading coding for CPU implemented... LOL...)

i think it's obvious that the cpu, at least as we know it, won't be around for much longer, more than likely by 2011-2012 we will be using hybrid gpu/cpu chips, with the gpu handling the brunt of the heavy lifting and the cpu portion just being there to pass the data to the gpu. -

But I do like seeing newer applications being developed for GPUs, it's just that most need major improvement -

"A very important new addition to the GeForce GTX 200 GPU architecture is double-precision, 64-bit floating point computation support. This benefits various high-end scientific, engineering, and financial computing applications or any computational task requiring very high accuracy of results. Each SM incorporates a double-precision 64-bit floating math unit, for a total of 30 double-precision 64-bit processing cores.
The double-precision unit performs a fused MAD, which is a high-precision implementation of a MAD instruction that is also fully IEEE 754R floating-point specification compliant. The overall double-precision performance of all 10 TPCs of a GeForce GTX 200 GPU is roughly equivalent to an eight-core Xeon CPU, yielding up to 90 gigaflops.” -

Don't get me wrong, I think it's great with all this new GPU development, and OpenCL looks very promising. But CPU will not be gone anytime soon. GPU can only do very specific things, unfortunately -
This has got to be at least 1000th time when some enlightened soul here or there seriously announces "death of ..." (PC, CPU, Windows, etc)
Yet since I was kid and had my first computer I still see everybody use the very same basic design: CPU, RAM, HDD, monitor, mouse, keyboard (and add Windoze for most of people).
Even if GPU could and would replace CPU, what would it change?
GPU would become CPU at this moment, geez.
When math co-processors were incorporated into CPU did we called them out of the sudden "CPU With Built-In Math Co-Processor"? No, they were still just "CPU".
When GPU's architecture become as versatile and powerful as CPUs (and they will), of course there will be no need for some "separate CPU" anymore - but such GPU will be the CPU of such system. And no one will call it "GPU" at that moment, since this chip will be the system's Central Processing Unit, aka CPU
BTW
deadrats, you already started another thread about it. What was the point to open this one - you didn't like some replies in your previous thread?
No matter how many threads you start, it won't change the facts that GPU won't replace CPU - and if it will, it will become the CPU itself. -
People are creative, they will always find demand for more power, even if it is just for bragging rights
That said, I believe I read that Adobe CS4 does in fact have at least some support for CUDA. That said, a CPU is still needed for many tasks, particularly in a high end server environment.Some people say dog is mans best friend. I say that man is dog's best slave... At least that is what my dogs think. -
well it appears that intel has moved up the mass production of its clarkdale cpu to the 4th quarter of this year:
http://www.engadget.com/2009/06/29/intels-32nm-clarkdale-cpus-moved-up-to-q4-a-full-year-ahead-of/
for thos of you that don't know the clarkdale is the cpu with the integrated gpu, here's a video of a pre-production sample in action:
http://www.tweaktown.com/news/12378/intel_shows_clarkdale_system_with_on_chip_gpu/index.html -
My almost 2 years old PocketPC has CPU with built-in GPU.
And still there are no programs to utilize GPU's-side processing power
Intel is going in right direction with Clarkdale chip.
Anyways.
All the low-end office machines and such should have always had some cheap GPU-co-processor already built-in on CPU's die or chipset, eliminating old AGP slots entirely (if they would remove old PCI or any other "expansion" slots, the low-end business machines should have been fit inside monitor's case by now, and probably that's where it will go).
There are thousands of office "low end, cheap" boxes that could have been basically shrunk to slightly more than the size of CPU and heatsink is, if it weren't for all the useless ports and slots. Why they ever needed AGP, PCI or PCI-e slots on office machines? Those are usually just dumb terminals anyways. 2 USBs + VGA + LAN is all any office dumb box needs. Built GPU in into CPU, built in memory, and it fits inside any monitor
