Very first benchmarks for the new G5 dualcore

The website http://media.99mac.se proudly published the first tests of the new PowerMacs G5 dual-core 2GHz and 2.3GHz.
The two computers have been benchmarked with XBench to a G5 Dual 2.5Ghz. Even though this soft is far from a perfect benchmarking solution, it still shows that the new 2.3GHz dual-core is faster than the older Dual 2.5GHz, which is good news for those who intended to buy these new machines, or even better the Quad 2.5GHz!
Surprisingly, the new dual-core gets better marks than the older models in the field of memory access. The other way round was expected. Possibly, a bigger amount of L2 cache memory plus a higher data rate from and to the SDRAM (albeit its latency is higher) might have balanced the loss of a data bus. Then we can only expect great performances from the Quad G5!
Next logical step would be to have one of these computer run demanding softwares heavily relying on RAM access. That way we would really get a clear picture of what they really have in the guts.
Surprisingly too are the graphics results of the 2.3GHz dual-core/Geforce 6600 couple, which are better than those of the 2.5GHz dual/6800 Ultra. I don't think that PCI-Express has anything to do with that although it is a possibility that the driver of the 6800 is not really optimized. These should be checked through "real life benchmarking" with games like Doom 3 or applications making generous use of the graphic card.
