GeForce GTX 460 (OEM) vs GeForce GTX 750

Intro

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

GeForce GTX 750		80000 MB/sec
	Difference: 28800 (36%)

Texel Rate

The GeForce GTX 460 (OEM) should be a bit (about 12%) faster with regards to anisotropic filtering than the GeForce GTX 750. (explain)

GeForce GTX 460 (OEM)		36400 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 3760 (12%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 460 (OEM) is superior to the GeForce GTX 750, by a large margin. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
GeForce GTX 750		16320 Mpixels/sec
	Difference: 4480 (27%)

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 max amount of data (counted in MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
