GeForce GTX 980 vs Radeon HD 5970

Intro

The GeForce GTX 980 comes with clock speeds of 1126 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 2048 SPUs as well as 128 TAUs and 64 Rasterization Operator Units.

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 980 165 Watts
Radeon HD 5970 294 Watts
Difference: 129 Watts (78%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5970 should be a bit faster than the GeForce GTX 980 overall. (explain)

Radeon HD 5970 256000 MB/sec
GeForce GTX 980 224000 MB/sec
Difference: 32000 (14%)

Texel Rate

The Radeon HD 5970 will be quite a bit (approximately 61%) better at texture filtering than the GeForce GTX 980. (explain)

Radeon HD 5970 232000 Mtexels/sec
GeForce GTX 980 144128 Mtexels/sec
Difference: 87872 (61%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 5970 is the winner, and very much so. (explain)

Radeon HD 5970 92800 Mpixels/sec
GeForce GTX 980 72064 Mpixels/sec
Difference: 20736 (29%)

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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most 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 number of ROPs by the clock speed of the card. 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 many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
