GeForce GTX Titan 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 running at 1000 MHz through a 256-bit bus. It also is made up of 1600 SPUs, 160 TAUs, and 64 Raster Operation Units.

Radeon HD 5970		256000 MB/sec
	Difference: 32384 (13%)

Texel Rate

The Radeon HD 5970 is quite a bit (approximately 24%) more effective at texture filtering than the GeForce GTX Titan. (explain)

Radeon HD 5970		232000 Mtexels/sec
GeForce GTX Titan		187488 Mtexels/sec
	Difference: 44512 (24%)

Pixel Rate

The Radeon HD 5970 should be much (more or less 131%) faster with regards to full screen anti-aliasing than the GeForce GTX Titan, and also should be able to handle higher resolutions while still performing well. (explain)

Radeon HD 5970		92800 Mpixels/sec
GeForce GTX Titan		40176 Mpixels/sec
	Difference: 52624 (131%)

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: Bandwidth is the max amount of data (in units of megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes 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 get to the max fill rate.
