GeForce GTX 750 vs Radeon HD 5970

Intro

Compare those specifications to the Radeon HD 5970, which comes with GPU clock speed of 725 MHz, and 1024 MB of GDDR5 memory set to run at 1000 MHz through a 256-bit bus. It also is comprised of 1600 Stream Processors, 160 Texture Address Units, and 64 ROPs.

GeForce GTX 750		80000 MB/sec
	Difference: 176000 (220%)

Texel Rate

The Radeon HD 5970 should be quite a bit (more or less 611%) more effective at anisotropic filtering than the GeForce GTX 750. (explain)

Radeon HD 5970		232000 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 199360 (611%)

Pixel Rate

If using a high resolution is important to you, then the Radeon HD 5970 is superior to the GeForce GTX 750, by far. (explain)

Radeon HD 5970		92800 Mpixels/sec
GeForce GTX 750		16320 Mpixels/sec
	Difference: 76480 (469%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the 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 that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
