GeForce 8800 GT 512MB vs GeForce GTX 750

Intro

Compare that 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 memory. 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 GT 512MB		105 Watts
	Difference: 50 Watts (91%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 750 should in theory be quite a bit superior to the GeForce 8800 GT 512MB overall. (explain)

GeForce GTX 750		80000 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 22400 (39%)

Texel Rate

The GeForce 8800 GT 512MB should be a small bit (about 3%) more effective at anisotropic filtering than the GeForce GTX 750. (explain)

GeForce 8800 GT 512MB		33600 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 960 (3%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 750 is a better choice, by a large margin. (explain)

GeForce GTX 750		16320 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 6720 (70%)

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 max amount of data (measured in megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the 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 card can possibly record to the 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 card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
