GeForce 8800 GTX vs GeForce GTX 750

Intro

Compare those specs to the GeForce GTX 750, which comes with a core clock speed of 1020 MHz and a GDDR5 memory speed of 1250 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 512 SPUs, 32 TAUs, and 16 Raster Operation 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 theoretically be a little bit superior to 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 will be a bit (approximately 13%) faster with regards to texture 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 lots of anti-aliasing is important to you, then the GeForce GTX 750 is superior to the GeForce 8800 GTX, not by a very large margin though. (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 data (counted in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling 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 chip could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of 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 output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
