GeForce 8800 GTS (G80) 640MB vs GeForce GTX 960M

Intro

The GeForce 8800 GTS (G80) 640MB makes use of a 90 nm design. nVidia has set the core frequency at 513 MHz. The GDDR3 memory works at a speed of 792 MHz on this model. It features 96 SPUs as well as 48 TAUs and 20 ROPs.

Compare those specs to the GeForce GTX 960M, which features core speeds of 1096 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Pixel Rate

The GeForce GTX 960M should be quite a bit (more or less 71%) better at full screen anti-aliasing than the GeForce 8800 GTS (G80) 640MB, and also should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 960M 17536 Mpixels/sec
GeForce 8800 GTS (G80) 640MB 10260 Mpixels/sec
Difference: 7276 (71%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
