GeForce GTX Titan vs Radeon HD 5970

Intro

The GeForce GTX Titan features a GPU core clock speed of 837 MHz, and the 6144 MB of GDDR5 memory runs at 1502 MHz through a 384-bit bus. It also is made up of 2688 Stream Processors, 224 TAUs, and 48 ROPs.

Compare those specs to the Radeon HD 5970, which features core speeds of 725 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 1600 SPUs as well as 160 Texture Address Units and 64 Rasterization Operator Units.

GeForce GTX Titan 187488 Mtexels/sec
Difference: 44512 (24%)

Pixel Rate

The Radeon HD 5970 will be much (more or less 131%) better at anti-aliasing than the GeForce GTX Titan, and also able to handle higher resolutions better. (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.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. 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 rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
