Rivastation heeft een artikel in elkaar gedraaid die de performance van een Riva TNT op een PII-300 en een PII-450 vergelijkt, om zo te zien hoe het met de schaalbaarheid van de TNT:
So what can we learn from all these values? The TNT does not scale as well as the RIVA128. I estimate that you can reach the limits with a CPU between 350MHz to 400Mhz. After that you wonīt see a increase anymore because the TNT canīt handle the higher amount of data that comes from the CPU.
Another interesting thing is 3DNow!. With the limits of the TNT you wonīt see values that are very much faster because the TNT canīt handle the larger amount of data.
But what about the BUS-system of the PC? Is the rest of the PC or the AGP Bus the limitating factor that canīt handle that high amount of data and itīs not the vault of the TNT that you canīt increase the values anymore?
Only NVIDIA will know the answer... Iīll run some tests with overclocking the TNT soon to get a answer for that.
At all you must say that the limits of the TNT are in very high regions. Another fact is that modern games like the announced Falcon4 do more than only 3D graphics. Falcon4 simulates a whole virtual Battlefield in realtime, and does a lot 3D Graphics at the same time. So you will need a fast CPU here!
I havenīt found a benchmark yet that takes cares of that point. Today benchmarks do only test a script based run. CPU power is tested in CPU only tests, like in 3DMARK99.
But to compare results you need the same situation every time.... a vicious circle. Maybe you need some kind of Fuzzy Logic here.
