GeForce 8800 GTS (G80) 320MB vs GeForce 9500 GT DDR2
Intro
The GeForce 8800 GTS (G80) 320MB features core clock speeds of 513 MHz on the GPU, and 792 MHz on the 320 MB of GDDR3 memory. It features 96 SPUs as well as 48 Texture Address Units and 20 ROPs.Compare those specifications to the GeForce 9500 GT DDR2, which features a clock frequency of 550 MHz and a DDR2 memory speed of 500 MHz. It also makes use of a 128-bit bus, and makes use of a 65 nm design. It is comprised of 32 SPUs, 16 Texture Address Units, and 8 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.

Comments
One Response to “GeForce 8800 GTS (G80) 320MB vs GeForce 9500 GT DDR2”I am going to put the 2 in the same rig for a week each and see who is who at seti@home CUDA tasks. I had previously run a 9800 GT. It should be noted I have the PNY 9500 GT, the 8800 GTS is a version made by EVGA as a "eGeForce" not sure but suspect it has nothing to do with the cards abilities.
