GeForce GTX 460 vs Radeon HD 5750 1GB

Intro

Compare that to the Radeon HD 5750 1GB, which features GPU clock speed of 700 MHz, and 1024 MB of GDDR5 memory set to run at 1150 MHz through a 128-bit bus. It also is comprised of 720(144x5) Stream Processors, 36 Texture Address Units, and 16 ROPs.

GeForce GTX 460		37800 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 12600 (50%)

Pixel Rate

The GeForce GTX 460 should be quite a bit (about 45%) better at full screen anti-aliasing than the Radeon HD 5750 1GB, and also should be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 460		16200 Mpixels/sec
Radeon HD 5750 1GB		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 max amount of information (measured in megabytes per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 applied per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
