GeForce GTX 460 (OEM) vs Radeon HD 7750

Intro

Compare all of that to the Radeon HD 7750, which makes use of a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 memory is set to run at a frequency of 1125 MHz on this specific card. It features 512 SPUs as well as 32 Texture Address Units and 16 ROPs.

Radeon HD 7750		72000 MB/sec
	Difference: 36800 (51%)

Texel Rate

The GeForce GTX 460 (OEM) will be quite a bit (more or less 42%) faster with regards to anisotropic filtering than the Radeon HD 7750. (explain)

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

Pixel Rate

The GeForce GTX 460 (OEM) should be quite a bit (about 63%) faster with regards to FSAA than the Radeon HD 7750, and also will be able to handle higher screen resolutions without slowing down too much. (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 largest amount of data (in units of megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR 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 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

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