GeForce GTX 750 vs Radeon HD 5570

Intro

Compare all of that to the Radeon HD 5570, which uses a 40 nm design. AMD has set the core speed at 650 MHz. The DDR3 RAM is set to run at a speed of 900 MHz on this specific card. It features 400(80x5) SPUs as well as 20 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5570		43 Watts
GeForce GTX 750		55 Watts
	Difference: 12 Watts (28%)

Memory Bandwidth

The GeForce GTX 750 should theoretically be much faster than the Radeon HD 5570 overall. (explain)

GeForce GTX 750		80000 MB/sec
Radeon HD 5570		28800 MB/sec
	Difference: 51200 (178%)

Texel Rate

The GeForce GTX 750 is quite a bit (more or less 151%) more effective at anisotropic filtering than the Radeon HD 5570. (explain)

GeForce GTX 750		32640 Mtexels/sec
Radeon HD 5570		13000 Mtexels/sec
	Difference: 19640 (151%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 750 is the winner, by a large margin. (explain)

GeForce GTX 750		16320 Mpixels/sec
Radeon HD 5570		5200 Mpixels/sec
	Difference: 11120 (214%)

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 largest amount of information (measured in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 can be applied per 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount 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 fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
