AMD's Showcases Quad-Core Barcelona CPU

Posted by Zonk on from the four-times-the-fun dept.

Gr8Apes writes "AMD has showcased their new 65nm Barcelona quad-core CPU. It is labeled a quad-core Opteron, but according to Infoworld's Tom Yeager, is really a redefinition of x86. Each core has a new vector math processing unit (SSE128), separate integer and floating point schedulers, and new nested paging tables (to vastly improve hardware virtualization). According to AMD, the new vector math units alone should improve floating point operation by 80%. Some analysts are skeptical, waiting for benchmarks. Will AMD dethrone Intel again? Only time will tell."

    I just got a presentation on gotoBLAS from the creator http://www.tacc.utexas.edu/~kgoto/, and his benchmarks show core2 duo nearly double the FLOPS of the opteron.

    perhaps you need to write some more cache efficient code to test with. goto BLAS can feed the beast like no other.
