GeForce GTX 980 vs Radeon HD 5970

Intro

The GeForce GTX 980 has core 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 Texture Address Units and 64 Rasterization Operator Units.

Compare that to the Radeon HD 5970, which has a clock frequency of 725 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 256-bit memory bus, and makes use of a 40 nm design. It is comprised of 1600 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

GeForce GTX 980 224000 MB/sec
Difference: 32000 (14%)

Texel Rate

The Radeon HD 5970 should be a lot (about 61%) faster with regards to 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

The Radeon HD 5970 will be quite a bit (about 29%) more effective at FSAA than the GeForce GTX 980, and also should be capable of handling higher resolutions while still performing well. (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 maximum amount of data (measured in MB per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few 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.
