Tom heeft een follow-up gepost op zijn VIA Apollo KX133 review van gisteren. In deze review bleek dat de Athlon in de SPECviewperf benchmarks onder NT veel lagere resultaten behaalde dan de Pentium III, wat vreemd was aangezien de Athlon met dezelfde benchmarks sneller was onder Windows 98. nVidia stuurde Tom een nieuwe NT drivertje, die wonderen bleek te verrichten. De Athlon+KX133 is met de nieuwe wonderdriver in alle SPECviewperf benchmarks sneller dan de PIII+i840, in sommige benchmarks stegen de prestaties zelfs met meer dan 100%:
NVIDIA told me in the email containing the new drivers for KX133 that this new driver enables AGP4x on KX133. It cannot really be only that, because the SPECviewperf-scores under Windows98 with only AGP1x and only 100 MHz memory-bus are still higher than the initial NT-scores of Athlon with NVIDIA's rev. 3.68 drivers. This is a strong hint that more than only AGP4x has been enabled in the new driver. Whatever other features have been enabled in GeForce's new KX133-driver, they are still not enabled when using the AMD750-platform. There are only a few possible reasons I could think of. Either AMD750 runs so bad under NT that NVIDIA had to disable all those features (I consider this as rather unlikely), or NVIDIA didn't consider Athlon as a CPU that would be used in an OpenGL-platform, thus they didn't bother optimizing the NT-driver for AMD750 (in this case I blame AMD's product marketing for sleeping), or AMD didn't bother supporting NVIDIA properly for their development of drivers (something that I've heard from other companies before). I already asked NVIDIA to give me some kind of statement about that.
