GeForce GTX 560 vs Radeon HD 5670

Intro

Compare all that to the Radeon HD 5670, which makes use of a 40 nm design. AMD has set the core frequency at 775 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this particular card. It features 400(80x5) SPUs as well as 20 Texture Address Units and 8 ROPs.

Radeon HD 5670		61 Watts
GeForce GTX 560		150 Watts
	Difference: 89 Watts (146%)

Memory Bandwidth

The GeForce GTX 560 should theoretically perform quite a bit faster than the Radeon HD 5670 overall. (explain)

GeForce GTX 560		128128 MB/sec
Radeon HD 5670		64000 MB/sec
	Difference: 64128 (100%)

Texel Rate

The GeForce GTX 560 should be a lot (about 193%) more effective at texture filtering than the Radeon HD 5670. (explain)

GeForce GTX 560		45360 Mtexels/sec
Radeon HD 5670		15500 Mtexels/sec
	Difference: 29860 (193%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 560 is the winner, by far. (explain)

GeForce GTX 560		25920 Mpixels/sec
Radeon HD 5670		6200 Mpixels/sec
	Difference: 19720 (318%)

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 MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
