GeForce GTX 460 2GB vs Radeon HD 7750

Intro

Compare all of that to the Radeon HD 7750, which features core speeds of 800 MHz on the GPU, and 1125 MHz on the 1024 MB of GDDR5 memory. It features 512 SPUs along with 32 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 7750		55 Watts
GeForce GTX 460 2GB		160 Watts
	Difference: 105 Watts (191%)

Memory Bandwidth

In theory, the GeForce GTX 460 2GB should be 60% faster than the Radeon HD 7750 in general, because of its greater data rate. (explain)

GeForce GTX 460 2GB		115200 MB/sec
Radeon HD 7750		72000 MB/sec
	Difference: 43200 (60%)

Texel Rate

The GeForce GTX 460 2GB is much (more or less 48%) better at AF than the Radeon HD 7750. (explain)

GeForce GTX 460 2GB		37800 Mtexels/sec
Radeon HD 7750		25600 Mtexels/sec
	Difference: 12200 (48%)

Pixel Rate

The GeForce GTX 460 2GB will be quite a bit (about 69%) faster with regards to anti-aliasing than the Radeon HD 7750, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 460 2GB		21600 Mpixels/sec
Radeon HD 7750		12800 Mpixels/sec
	Difference: 8800 (69%)

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 (measured in MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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.
