GeForce 8800 GTX vs GeForce GTX 750

Intro

Compare all of that to the GeForce GTX 750, which comes with a core clock frequency of 1020 MHz and a GDDR5 memory frequency of 1250 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It features 512 SPUs, 32 TAUs, and 16 ROPs.

GeForce GTX 750		55 Watts
GeForce 8800 GTX		155 Watts
	Difference: 100 Watts (182%)

Memory Bandwidth

Theoretically, the GeForce 8800 GTX should perform a bit faster 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 will be a little bit (more or less 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

The GeForce GTX 750 will be just a bit (about 18%) faster with regards to full screen anti-aliasing than the GeForce 8800 GTX, and also will be able to handle higher resolutions more effectively. (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 maximum amount of information (measured in MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
