GeForce 8800 GTX vs GeForce GTX 750

Intro

The GeForce 8800 GTX comes with a GPU core speed of 575 MHz, and the 768 MB of GDDR3 memory runs at 900 MHz through a 384-bit bus. It also is made up of 128 Stream Processors, 64 Texture Address Units, and 24 ROPs.

Compare all of that to the GeForce GTX 750, which has a clock speed of 1020 MHz and a GDDR5 memory frequency of 1250 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is comprised of 512 SPUs, 32 TAUs, and 16 ROPs.

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

Texel Rate

The GeForce 8800 GTX will be a small bit (more or less 13%) better 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

The GeForce GTX 750 is a small bit (about 18%) better at full screen anti-aliasing than the GeForce 8800 GTX, and capable of handling higher resolutions while still performing well. (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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
