The Test
The Slot-1 Pentium II Test System AnandTech used was configured as follows:
An Intel Celeron 300A clocked at 450MHz on an ABIT BX6 Motherboard
64MB Mushkin SEC PC100 SDRAM
Western Digital 5.1GB Ultra ATA Hard Drive
AOpen 32X IDE CD-ROM Drive
Windows 98 with all of the latest patches/drivers installed
The benchmark suite consisted of the following full version game titles
Forsaken wasn't used as it remained too unstable at overclocked CPU/RAM speeds
Quake 2 v3.17 using Demo1.dm2

Conclusion
Not much explaining is necessary here, at 125MHz, with a memory clock (MCLK) speed of 115MHz, the Riva TNT can really give you a nice performance increase, especially at 1024 x 768. This performance trend would lead one to believe that being able to run a TNT at 125MHz with a memory clock speed of 130MHz would provide a performance increase great enough to make the TNT a strong enough competitor to 3Dfx's empire to tilt the favor of quite a few Voodoo2 supporters. Just imagine the performance increase a true 0.25 micron TNT running at 125MHz with a 200MHz memory clock would yield...
