GeForce GTX 570 vs Radeon HD 5570

Intro

Compare all that to the Radeon HD 5570, which makes use of a 40 nm design. AMD has clocked the core frequency at 650 MHz. The DDR3 RAM works at a speed of 900 MHz on this card. It features 400(80x5) SPUs along with 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5570		43 Watts
GeForce GTX 570		219 Watts
	Difference: 176 Watts (409%)

Memory Bandwidth

Performance-wise, the GeForce GTX 570 should in theory be quite a bit better than the Radeon HD 5570 overall. (explain)

GeForce GTX 570		152000 MB/sec
Radeon HD 5570		28800 MB/sec
	Difference: 123200 (428%)

Texel Rate

The GeForce GTX 570 will be a lot (about 238%) better at anisotropic filtering than the Radeon HD 5570. (explain)

GeForce GTX 570		43920 Mtexels/sec
Radeon HD 5570		13000 Mtexels/sec
	Difference: 30920 (238%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 570 is superior to the Radeon HD 5570, and very much so. (explain)

GeForce GTX 570		29280 Mpixels/sec
Radeon HD 5570		5200 Mpixels/sec
	Difference: 24080 (463%)

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 maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
