GeForce 8800 GTX vs GeForce GTX 750 Ti

Intro

The GeForce 8800 GTX comes with clock speeds of 575 MHz on the GPU, and 900 MHz on the 768 MB of GDDR3 memory. It features 128 SPUs along with 64 Texture Address Units and 24 Rasterization Operator Units.

Compare those specs to the GeForce GTX 750 Ti, which features clock speeds of 1020 MHz on the GPU, and 1350 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 Ti 60 Watts
GeForce 8800 GTX 155 Watts
Difference: 95 Watts (158%)

Memory Bandwidth

Both cards have the exact same bandwidth, so theoretically they should have the same performance. (explain)

Texel Rate

The GeForce GTX 750 Ti will be a bit (approximately 11%) better at AF than the GeForce 8800 GTX. (explain)

GeForce GTX 750 Ti 40800 Mtexels/sec
GeForce 8800 GTX 36800 Mtexels/sec
Difference: 4000 (11%)

Pixel Rate

The GeForce GTX 750 Ti should be a little bit (more or less 18%) faster with regards to FSAA than the GeForce 8800 GTX, and should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 750 Ti 16320 Mpixels/sec
GeForce 8800 GTX 13800 Mpixels/sec
Difference: 2520 (18%)

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: Bandwidth is the maximum amount of information (counted in MB per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
