The goal of this article is to bring out a quick look at what SSE3 brings to the table for Opteron and the future revision E Athlon 64 cores. As desktop parts do not enable coherent HT links at all, the 1GHz support won't matter. Also, the newer A64 parts are already 90nm on organic packages. Other than the usual small tweaks we see between steppings, the only thing that will be new across the board for K8 processors is SSE3.
