Journal Journal: AMD Expands SSE Instructions, Excluding Intel's

AMD announced their proposal today for a new SSE instruction set, namely SSE5. The new instruction set won't be set to launch until 2009, so don't expect to see it in any Barcelona cores. Interestingly, SSE5 will not be backwards compatible with all of the previous generations of SSE, which has been the case for all SSE generations thus far. Intel's new SSE4 is launching in Penryn around the end of the year, but only a fraction of the SSE4 instructions will be supported in AMD's SSE5.
