- Manufacturers produced the GeForce 7600 GS and the GeForce 6800 GS with either 128MB, 256MB or 512MB of memory, which is used for the PC's graphics and video capabilities. The 7600 GS uses Double Data Synchronous Random Access Memory architecture, while the 6800 GS uses faster GDDR3 memory, based on the Graphics Double Data Rate standard.
- Each GeForce 7600 GS and the GeForce 6800 GS has a core clock, which is the speed of the card's processor; and a memory clock, which is the rate of the memory's operation. Nvidia 7600 GS cards typically have a core clock of 400MHz and memory clock range of 250MHz to 500MHz. GeForce 6800 GS cards tend to be faster, with a core clock range of 425MHz to 490MHz and memory clock range of 500MHz to 650MHz.
- The memory bandwidth of the GeForce 7600 GS and the GeForce 6800 GS, which is a measurement of read and stored data, determines the ability of each card to handle functions such as display quality, or resolution. The 7600 GS has a memory bandwidth of 12.8GB per second. The 6800GS almost triples that number, with 32 GB/sec.
Texture Fill Rate
- A video card's texture fill rate is the amount of texture pixels, or texels, that are displayed on the computer screen of the PC each second. The 7600 GS generates 4,000 megatexels per second, which can be translated into 4 billion texels. The texture fill rate of the 6800 GS is 5,100 megatexels per second, or 5.1 billion texels.
