AMD does 4.7 Tera-flops, while Intel could hardly get 1TF at peaks in Larrabee. See also, in German: http://www.heise.de/newsticker/meldung/Intel-macht-Rueckzieher-bei-Larrabee-878138.html

The SGEMM benchmark is actually just one of the components of the Linpack benchmark, the single-precision matrix-multiply component actually. They made a big deal out of it, as if the SGEMM was a great accomplishment, as if it was as important as the overall Linpack, but then the next day they announced they're cancelling it. Yousuf Khan

For me it looks like Intel is going to promote and optimize open standard heterogeneous multicore programming (OpenCL). They are probably giving Larrabee to software companies that can do it better than Intel (Codeplay for example). I don't think it's a falure. It could be a smart move in a long run and good for everybody. Jenia.

Jenia. --------------------- Does anyone know if AMD/ATI are going to endorse OpenCL? btw: Jenia it looks like your news reader isent set up correctly, or perhaps its mine, but it dosent insert the > in front of the quoted text you have written! As it does with other peoples! On second thougth it looks like you are posting from Google so its their mistake!
