GeForce 8800 GTX vs GeForce GTX 750

Intro

Compare those specs to the GeForce GTX 750, which comes with core clock speeds of 1020 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 RAM. It features 512 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

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

As far as performance goes, the GeForce 8800 GTX should in theory be just a bit better 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 is a little bit (about 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

If running with high levels of AA is important to you, then the GeForce GTX 750 is a better choice, but it probably won't make a huge difference. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
