Sse5

[NewsBot]

I read that Intel says that they are not going to adopt SSE5, but I was looking at the SSE5 instructions today and I think that they would be really good for scientific computations (e.g. the Fast Fourier transform, the Generalized Born equation, etcetera).

 

Does anyone think that Intel will change its mind and adopt SSE5 in their future processors like they did for x86-64, which I understand, was with Microsoft's persuation (hint, hint)?

 

Edit: It seems I might get my wish in a slightly different form:

"Intel AVX: The next step in the Intel instruction set --Gelsinger also discussed Intel AVX (Advanced Vector Extensions) which,when used by software programmers, will increase performance infloating point, media, and processor intensive software. AVX can alsoincrease energy efficiency, and is backwards compatible to existingIntel processors. Key features include wider vectors, increasing from128 bit to 256 bit wide, resulting in up to 2x peak FLOPs output.Enhanced data rearrangement, resulting in allowing data to be pulledmore efficiently, and three operand, non-destructive syntax for a rangeof benefits. Intel will make the detailed specification public in earlyApril at the Intel Developer Forum in Shanghai. The instructions willbe implemented in the microarchitecture codenamed "Sandy Bridge" in the2010 timeframe."

 

There are two things that stand out to me there. The first is the 256 bit vectors and the second is the three operand instructions. As long as all of the things AMD is implementing in SSE5 are supported, these will make me very happy.
