GeForce GTX 460 SE vs Radeon HD 7750

Intro

Compare those specs to the Radeon HD 7750, which uses a 28 nm design. AMD has set the core speed at 800 MHz. The GDDR5 RAM runs at a speed of 1125 MHz on this particular model. It features 512 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

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

Memory Bandwidth

The GeForce GTX 460 SE should in theory be much faster than the Radeon HD 7750 overall. (explain)

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

Texel Rate

The GeForce GTX 460 SE is quite a bit (more or less 22%) more effective at texture filtering than the Radeon HD 7750. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
Radeon HD 7750		25600 Mtexels/sec
	Difference: 5600 (22%)

Pixel Rate

The GeForce GTX 460 SE is a lot (more or less 63%) better at anti-aliasing than the Radeon HD 7750, and should be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 460 SE		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: Memory bandwidth is the max amount of data (in units of MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can 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 ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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 bandwidth is, the lower the potential to reach the maximum fill rate.
