Michael van AnandTech heeft een review van twee TNT2 Model 64 kaartjes (Gigabyte GA-622 en Guillemot Maxi Gamer Cougar) neer gekwakt. Zoals je wellicht zult weten gaat het hier om een gemankeerde TNT2's met 64 ipv 128-bits geheugen bus, en de gevolgen daarvan zijn vooral merkbaar bij snelle CPU's en hoge resoluties:
Overall, it’s clear that the 64-bit memory bus of the TNT2 M64 greatly hinders performance in certain situations, such as higher resolutions and/or color depths. Even on the Celeron 300A, performance drops much more rapidly than a standard TNT2 when switching to 32-bit, especially 800x600 or 1024x768.The K6-2/450 is not effected nearly as much until you hit 1024x768 because it is more CPU limited. The drop incurred by switching to 32-bit rendering at 800x600 is much more significant with the M64 as well.
As CPU power is increased, the performance difference between the M64 and the TNT2 become much more evident. The M64 hangs tight at 640x480x16, but falls behind quickly at any higher setting. In fact, the frame rate drops up to 30% compared to a similarly clocked standard TNT2 under such conditions.
