Geforce GTX 760 vs Radeon HD 5970

Intro

Compare those specs to the Radeon HD 5970, which makes use of a 40 nm design. AMD has clocked the core speed at 725 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this specific card. It features 1600 SPUs along with 160 Texture Address Units and 64 ROPs.

Geforce GTX 760		94080 Mtexels/sec
	Difference: 137920 (147%)

Pixel Rate

The Radeon HD 5970 is much (approximately 196%) faster with regards to AA than the Geforce GTX 760, and also capable of handling higher resolutions more effectively. (explain)

Radeon HD 5970		92800 Mpixels/sec
Geforce GTX 760		31360 Mpixels/sec
	Difference: 61440 (196%)

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 largest amount of information (measured in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 are applied per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
