Developers of graphics processing units (GPUs) have been talking about the possibility of general-purpose (GP) computing on graphics chips for over six years now, however, very few actual have been achieved in the direction. Intel Corp. claims that GPGPU hardly has any future and serious intentions to promote it, such as Nvidia Corp.’s compute unified device architecture (CUDA), will never be successful.

“The problem that we’ve seen over and over and over again in the computing industry is that there’s a cool new idea, and it promises a 10x or 20x performance improvements, but you’ve just got to go through this little orifice called a new programming model. Those orifices have always been insurmountable as long as the general purpose computing models evolve into the future,” said Patrick P. Gelsinger, senior vice president and general manager of Intel’s digital enterprise group, reports Custom PC web-site.

Intel knows what it is talking about: it has Itanium microprocessors based the explicitly parallel instruction computing (EPIC) paradigm. Such processors may truly deliver extreme performance, but this requires substantial optimization of software, something, which is why Intel Itanium processors cannot reach desktops or even mainstream workstations.

Since Intel’s forthcoming discrete graphics processing unit code-named Larrabee has many x86 cores inside, Mr. Gelsinger believes that Nvidia’s compute unified device architecture (CUDA) and Advanced Micro Devices close to metal (CTM) initiatives would eventually vanish into oblivion.

“We expect things like CUDA and CTM will end up in the same interesting footnotes in the history of computing annals – they had great promise and there were a few applications that were able to take advantage of them, but generally an evolutionary compatible computing model, such as we’re proposing with Larrabee, we expect will be the right answer long term,” Mr. Gelsinger added.

Intel has been great up to now, but this is ridiculous. Intel wants to trap us in THEIR idea of the way we should compute. It is time we break the shackles of x86 and embrace better, faster ways of computing. In the end it is Intel that will be weeping (a little because Nehalem+4870 Crossfire = PWNAGE).

hey Wingless,

I don't understand this part of your comment "In the end it is Intel that will be weeping (a little because Nehalem+4870 Crossfire = PWNAGE)."
You do know that intel makes Nehalem so how is it they will be hurting?

if anything Nvidia is the one hurting since intel won't give them a license to make chipsets for Nehalem and no SLI either.

I see how all of you guys get VERY excited when you read the names nVidia, AMD and Intel on the same line but let me ask you something - how many of you have actualy written a SINGLE line of CUDA code?

It is not about whose product is FASTER, but about which product a programmer will like to write code for, and let me tell you, CUDA is barely usable at that time. Dealing with parallelism is no easy task even on much higher abstraction levels (say in Java), and in CUDA it is straight hell. It is a masochistic job writing such code, which explains why you haven't seen tons of applications designed to run on your GPU, although CUDA has been around for some time now.
