GeForce 8800 GTX vs GeForce GTX 750

Intro

The GeForce 8800 GTX has core speeds of 575 MHz on the GPU, and 900 MHz on the 768 MB of GDDR3 RAM. It features 128 SPUs as well as 64 Texture Address Units and 24 ROPs.

Compare that to the GeForce GTX 750, which uses a 28 nm design. nVidia has clocked the core frequency at 1020 MHz. The GDDR5 RAM is set to run at a speed of 1250 MHz on this model. It features 512 SPUs as well as 32 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 55 Watts
GeForce 8800 GTX 155 Watts
Difference: 100 Watts (182%)

Memory Bandwidth

The GeForce 8800 GTX should theoretically perform a little bit faster than the GeForce GTX 750 in general. (explain)

GeForce 8800 GTX 86400 MB/sec
GeForce GTX 750 80000 MB/sec
Difference: 6400 (8%)

Texel Rate

The GeForce 8800 GTX should be just a bit (about 13%) more effective at anisotropic filtering than the GeForce GTX 750. (explain)

GeForce 8800 GTX 36800 Mtexels/sec
GeForce GTX 750 32640 Mtexels/sec
Difference: 4160 (13%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 750 is superior to the GeForce 8800 GTX, but only just. (explain)

GeForce GTX 750 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 largest amount of data (counted in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
