GeForce GTX 570 vs Radeon HD 5750 1GB

Intro

Compare that to the Radeon HD 5750 1GB, which makes use of a 40 nm design. AMD has set the core frequency at 700 MHz. The GDDR5 memory works at a speed of 1150 MHz on this specific model. It features 720(144x5) SPUs along with 36 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5750 1GB		86 Watts
GeForce GTX 570		219 Watts
	Difference: 133 Watts (155%)

Memory Bandwidth

In theory, the GeForce GTX 570 should be 107% quicker than the Radeon HD 5750 1GB in general, because of its higher bandwidth. (explain)

GeForce GTX 570		152000 MB/sec
Radeon HD 5750 1GB		73600 MB/sec
	Difference: 78400 (107%)

Texel Rate

The GeForce GTX 570 should be much (approximately 74%) better at anisotropic filtering than the Radeon HD 5750 1GB. (explain)

GeForce GTX 570		43920 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 18720 (74%)

Pixel Rate

The GeForce GTX 570 will be quite a bit (about 161%) better at full screen anti-aliasing than the Radeon HD 5750 1GB, and should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 570		29280 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 18080 (161%)

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 data (counted in megabytes per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units 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 maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes 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 of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
