Benchmarks with SiSoft Sandra problematic

A review of the ABit KR7-RAID with the VIA KT266A chipset appeared on the American hardware site '[H] ardOCP' on Thursday. In addition to this interesting comparison with the reference mainboard from VIA, the synthetic benchmark SiSoft Sandra stood out once again.

This benchmark allows testing of many different performance values ​​of the PC, including the main memory. In the Review it was noticed that in a new version of the Tool the values ​​for the memory transfer were suddenly drastically higher than in previous versions. For comparison, the screenshots with the new version and the old . It is noticeable that the values ​​for the tested VIA KT266A chipset for the transfer values ​​are 80% higher for the memory transfer via the FPU and 100% for transfers via the CPU than with the old version. In comparison, the i850 chipset 'only' achieved an increase of 57% and 59% for the corresponding values. To explain this, reference was made to a new option in the benchmarks, which in the new version carries out a buffered benchmark as a default setting, which supposedly should represent the practical performance more than the old benchmark, which was mainly based on theoretical throughput. To what extent this is true remains to be seen, but the fact is that in practice, in the vast majority of cases, the 50% increased performance that the i850 chipset had shown in Sandra's memory benchmark could not be reproduced in practice. In this respect it is certainly to be welcomed that this is now also taken into account in synthetic benchmarks, on the other hand one wonders what one can believe now.
