The roadmap for AMD looks very strong. There is no question that Barcelona-based servers will have higher performance and higher performance per watt than anything from Intel when they start selling in Q3. Intel has to get to Nehalem before that will change, if it changes. Penryn and its ilk are simply Core 2 on a smaller process, not a new architecture. Anyone who thinks that Penryn SSE4 will make a signficant differnce is not thinking properly. How much low-handing fruit do you think could possibly be left after SSE, SSE2, AMD64, and SSE3? Penryn is a non-issue. Almost everything you wrote above is false. In fact, I'm having trouble finding a single correct assertion. This board has been awash in public information over the past few weeks that debunks all of those claims.

Petz, > Anyone who thinks that Penryn SSE4 will make a signficant differnce is not thinking properly. How much low-handing fruit do you think could possibly be left after SSE, SSE2, AMD64, and SSE3? Your conclusion is wrong. It's processor microarchitecture that has a severe lack of low-hanging fruit. Having already squeezed IPC like blood out of a rock, the new trend is thread-level parallelism, but even that has severe diminishing returns past quad-core. (The effect is that 4-socket servers are on their way out.) So now we're going back to adding more instructions so that you don't have to execute as many. Fewer cycles to execute a task means more performance for less power. Tenchusatsu
