De G400 is toch wel de heetste kaart van dit moment. GA-Source doet een review van het ding, en net zoals andere sites zijn ze erg positief over het ding. Vooral de snelle handling van grote textures en het vrijwel ontbreken van een performance hit bij het switchen van 16 naar 32-bit kleurdiepte:
This is most likely due to the internal 256 bit memory pipeline of the G400. With it able to pass textures more rapidly internally, a larger texture does not cause as much of a performance hit. Definitely 32mb is well worth it on the G400, and in some ways I would really like to see a 64mb version, if the chipset supported it. The other thing that this tells me I need to do (as well as the processor/memory upgrade I mentioned before) is test in multiple resolutions. I think that the G400 MAX would outperform the Ultra TNT/2 in 3D Winbench and 3D Mark99 at 1280x1024 or 1600x1200.
This memory pipeline is also the reason that the 16-32 bit color switch caused almost no performance loss (especially compared to the competition). Looking at all of the numbers, you can see that the jump from 640x480 to 1024x768 caused much less of a performance drop (on average) than with the other cards. By having so much more internal memory bandwidth than most other cards, the G400 is limited only by its (and the CPU of the computer it is in) processing speed, not by memory access speeds.
De benchmarks van GA-Source laten het bekende beeld zien: G400 relatief traag op lage resoluties, maar snel op hoge resoluties en bij 32-bit kleur, de OpenGL driver suckt nog.
