Kind of funny how people say 939 is faster etc, when they don't provide benchmarks to prove it. And by the way, newcastle cores support see and sse2, just not sse3. There is like a 3-4% difference in processor performance of the same speeds because of that, but not extremetly noticible. The only things venices do however have a better integrated memory controller, and is more stable when overclocking. Finally, dual channel does not provide as extreme of a benefit in AMD k8 systems as it does with p4s because of the integrated memory controller. Finally, if you do a search of xbit labs on palmero, you will see what i mean. When comparing the old paris core based on 130mm newcastle core with the 90mm winchester core of the same clock speeds, you will see that there is very little difference. Also, when you compare the old 90 mm sempron core with the new one based on the E stepping,(which is venice core), you will see that there is almost no performance increase.
