P3D (Pure 3D News) heeft een review gepost van de Guillemot Maxi Gamer Xentor, met o.a. info over het overklokken van de Xentor TNT2:
The Xentor 16MB is clocked at a default setting of 125 Mhz, easily overclockable to 150 Mhz. SDRAM memory is clocked at 166 Mhz. Guillemot does not provide an overclocking utility, so you'll have to use a third-party utility like Powerstrip. As it is, results are pretty impressive, with a total of 260 million texture-mapped pixels/sec, compared to 283 for the Voodoo 3 2000 (you could barely tell the difference). An advantage over the Voodoo 3 2000 is the 32 bit color and large texture support; overall the TNT2 produces cleaner and brighter images than 3Dfx's chips, and the nVidia bundled demos really show that off.
