GeForce GTX 980 vs Radeon HD 5570

Intro

Compare 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 memory runs at a speed of 900 MHz on this specific model. It features 400(80x5) SPUs as well as 20 TAUs and 8 ROPs.

Radeon HD 5570		28800 MB/sec
	Difference: 195200 (678%)

Texel Rate

The GeForce GTX 980 will be quite a bit (approximately 1009%) better at anisotropic filtering than the Radeon HD 5570. (explain)

GeForce GTX 980		144128 Mtexels/sec
Radeon HD 5570		13000 Mtexels/sec
	Difference: 131128 (1009%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 980 is the winner, by far. (explain)

GeForce GTX 980		72064 Mpixels/sec
Radeon HD 5570		5200 Mpixels/sec
	Difference: 66864 (1286%)

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 information (in units of MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
