AMD's Jaguar to Support AVX

The quote:

"We are expecting some changes to tunings and costs. We will update them in near future. There are ISA changes as well like btver2 supports AVX, BMI."

It was recently reported that AMD scrapped SSE5 in favor of AVX, which is likely to also introduce SSE4 in Jaguar. Jaguar's predecessor Bobcat only supports SSE3.

Kabini is expected to be released in 2013 as a low-price and low-power mobile processor with up to four cores and a power envelope spanning 9 to 25 watts. The program of the upcoming Hot Chips 24 conference in Cupertino indicates that AMD will be revealing more information about Jaguar at the end of August.

    AVX is interesting in its own right, but BMI? As Bobcat had the same instruction set support as K10, I'd have thought it already supported POPCNT and LZCNT as well as SSE4a.

    Supporting SSE4.1 and 4.2 is a good move, but will it make for a far more complex core?

    In b4 "Not as fast as my core i7 with 16 gigs of ram and a $700 Nvidia that self destructs with the odd numbered beta drivers" comments.

    And yet another reason to hold off on purchasing another laptop... again.

    Oh man, I havn't thought of Assembler in decades. Thanks for reminding an old programmer about the good times. Now to read up on the SSE4.1 ops for an asm fix.
