GeForce 8800 GTX vs GeForce GTX 750

Intro

Compare those specifications to the GeForce GTX 750, which comes with 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 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

Theoretically, the GeForce 8800 GTX should be just a bit faster than the GeForce GTX 750 overall. (explain)

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

Texel Rate

The GeForce 8800 GTX should be a 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 (more or less 18%) more effective at AA than the GeForce 8800 GTX, and also should be capable of handling higher resolutions without losing too much performance. (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: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output 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 get to the max fill rate.
