GeForce GTX 460 vs Radeon HD 5750 512MB

Intro

Compare those specifications to the Radeon HD 5750 512MB, which makes use of a 40 nm design. AMD has clocked the core speed at 700 MHz. The GDDR5 RAM works at a speed of 1150 MHz on this particular card. It features 720(144x5) SPUs along with 36 Texture Address Units and 16 ROPs.

The GeForce GTX 460 will be quite a bit (more or less 50%) faster with regards to AF than the Radeon HD 5750 512MB. (explain)

GeForce GTX 460		37800 Mtexels/sec
Radeon HD 5750 512MB		25200 Mtexels/sec
	Difference: 12600 (50%)

Pixel Rate

The GeForce GTX 460 should be much (more or less 45%) more effective at anti-aliasing than the Radeon HD 5750 512MB, and will be able to handle higher screen resolutions better. (explain)

GeForce GTX 460		16200 Mpixels/sec
Radeon HD 5750 512MB		11200 Mpixels/sec
	Difference: 5000 (45%)

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 information (measured in MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. 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 lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
