Compare NVIDIA GeForce Versions


NVIDIA Chips Comparison Table

by hardwaresecrets


Above you can see a small part of the table click here for the complete table.

The right way to compare the memory performance of different chips is through their memory transfer rate, which is calculated using the formula (clock x bits per clock ) / 8.

From the table you may think GeForce 6600 GT is faster than a GeForce 6800 because it has a higher clock rate (500 MHz against 325 MHz). But GeForce 6800 accesses memory 256 bits at a time while GeForce 6600 GT accesses memory 128 bits at a time, and also GeForce 6800 processes 12 pixels per clock tick, while GeForce 6600 GT processes eight pixels per clock.

You have to be very carefull with low-end video cards using NVIDIA chips, because they can use different clock rates and different memory interface from the table. For example, you can find GeForce FX 5200, GeForce FX 5500 and GeForce 6600 with 64-bit or 128-bit interface. We’ve seen GeForce FX 5200, GeForce FX 5500 and GeForce 6200 with 32-bit interface on the market!
