GeForce GTX 460 (OEM) vs Radeon HD 7750

Intro

Compare those specifications to the Radeon HD 7750, which comes with a core clock frequency of 800 MHz and a GDDR5 memory speed of 1125 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 512 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 7750		55 Watts
GeForce GTX 460 (OEM)		150 Watts
	Difference: 95 Watts (173%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 (OEM) will be 51% faster than the Radeon HD 7750 in general, because of its higher bandwidth. (explain)

GeForce GTX 460 (OEM)		108800 MB/sec
Radeon HD 7750		72000 MB/sec
	Difference: 36800 (51%)

Texel Rate

The GeForce GTX 460 (OEM) will be much (more or less 42%) more effective at AF than the Radeon HD 7750. (explain)

GeForce GTX 460 (OEM)		36400 Mtexels/sec
Radeon HD 7750		25600 Mtexels/sec
	Difference: 10800 (42%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 460 (OEM) is a better choice, and very much so. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
Radeon HD 7750		12800 Mpixels/sec
	Difference: 8000 (63%)

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 within a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video 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 most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. 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.
