GeForce GTX 460 vs Radeon HD 5570

Intro

Compare all that to the Radeon HD 5570, which has core speeds of 650 MHz on the GPU, and 900 MHz on the 512 MB of DDR3 memory. It features 400(80x5) SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5570		43 Watts
GeForce GTX 460		150 Watts
	Difference: 107 Watts (249%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 is 200% quicker than the Radeon HD 5570 in general, because of its higher data rate. (explain)

GeForce GTX 460		86400 MB/sec
Radeon HD 5570		28800 MB/sec
	Difference: 57600 (200%)

Texel Rate

The GeForce GTX 460 should be a lot (more or less 191%) better at anisotropic filtering than the Radeon HD 5570. (explain)

GeForce GTX 460		37800 Mtexels/sec
Radeon HD 5570		13000 Mtexels/sec
	Difference: 24800 (191%)

Pixel Rate

The GeForce GTX 460 is quite a bit (about 212%) faster with regards to anti-aliasing than the Radeon HD 5570, and capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 460		16200 Mpixels/sec
Radeon HD 5570		5200 Mpixels/sec
	Difference: 11000 (212%)

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 (counted in megabytes per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
