I want to compare SSE3 instruction set of Intel's core 2 duo processor(orPresscot processor)and SSE4 instruction set of Intel's Penryn processor. I was able to find the details individually but I couldn't find the comparison between them( also I dont know to compare it). It would be great If anyone could provide the comparison or a place to find such comparisons. I have a short period(less than 24 hours) to do this, So I believe thatI will get the response from you asap.
If you're looking at some of the web search results for "Penryn new instructions," e.g. http://arstechnica.com/news.ars/post/20070417-intel-details-penryn-performance-sse4.html
I don't know how it can be made simpler, except by pointing out (as I already did) that Penryn CPUs are most often used to run the earlier instruction sets.
