[ Synthetic Benchmarks ]
The SiSoft2007 synthetic processor results are quite interesting. Already we have seen the synthetic benchmark programs tell us that these new Intel processors are much faster in 3D environments (3Dmark2003). Then we learnt that they offer memory performance comparable to that of a Pentium 4 660. Now we find that SiSoft2007 suggests that the ALU performance is only 10% greater on the Core 2 Duo E6700!
I believe this is where the majority of the performance increase is coming from and it can be seen in the SiSoft2007 multimedia performance test. Here the Core 2 Duo E6700 is an incredible 65% faster in the Floating-Point test than Intels previous dual-core king the Pentium D 950. The much more expensive Core 2 Extreme X6800 processor was just 8% faster than the Core 2 Duo E6700.
Super PI performance is based on time, the quicker the processor makes the calculations the quicker it finishes this test. As you can see, the current desktop processors at their standard frequencies all take around 36 seconds to complete the 1MB calculation. Overclocking any one of these three processors so that they would break the 30 second barrier would be a reasonably tough job. Therefore, to simply plug the Intel Core 2 Duo in to see a 19 second 1MB calculation result was spectacular. The Core 2 Extreme was even better, making the same calculation in just 17 seconds!
This PCmark2005 CPU test looks at file decryption and encryption performance and here the AMD Athlon64 loses out badly. However, the new Intel processors are not really able to gain any ground over the current Pentium 4 660 and D950 processors.
