On July 23 Intel will be releasing its next-generation x86 architecture, the one that will put it back in a full leadership position in the x86 space. The Core 2 architecture contains many features that make the Core 2 family performs better than AMD's chips. Yet most of the testings are based on 32-bit environment, one would wonder if the Core 2 still led in the 64-bit environment. The answer is sure, but with less performance gain than Pentium 4.
According to the internal document from the manufacturers (Intel Core 2 Extreme X6800 VS AMD Athlon 64 FX 62 & Intel Pentium XE 965), Pentium XE 965 could perform 5-10% (2-3% for Athlon 64 FX 62) better in 64-bit, Core 2 however was found no obvious boost.
The introduction of a macro-op fusion, where two instructions are executed simultaneously, will provide enhancements of floating point operations. The design of such implementation in Core 2 is based on 32-bit. But 64-bit environment contains less operation, Fusion is less useful. The case is similar to K8. Netburst however is an outstanding in the performance gain in 64-bit environment. The Trace Cache design in Pentium 4 benefits a longer instruction, in which will offer another 10-15% boost in 64-bit environment. In conclusion, Intel Core 2 family would provide a very good performance in 64-bit as in 32-bit, yet it’s no more gain between twos.

:doh: ....bij NORMAAL DESKTOP GEBRUIK,waarvoor deze cpu's dienen :games, office,surfen,fotoshop,video encoding etc. ;zult ge met een x2 5000+ of conroe E6600 wel best tevreden zijn voor de komende 2 jaar,ook in 64 bit
