GeForce GTX 970 vs Radeon Pro Duo

Intro

The GeForce GTX 970 features a GPU core clock speed of 1050 MHz, and the 4096 MB of GDDR5 RAM runs at 1750 MHz through a 256-bit bus. It also is made up of 1664 Stream Processors, 104 Texture Address Units, and 64 ROPs.

Compare all of that to the Radeon Pro Duo, which comes with a core clock frequency of 1000 MHz and a HBM memory frequency of 500 MHz. It also uses a 4096-bit bus, and uses a 28 nm design. It features 4096 SPUs, 256 Texture Address Units, and 64 Raster Operation Units.

GeForce GTX 970 224000 MB/sec
Difference: 800000 (357%)

Texel Rate

The Radeon Pro Duo should be a lot (approximately 369%) more effective at anisotropic filtering than the GeForce GTX 970. (explain)

Radeon Pro Duo 512000 Mtexels/sec
GeForce GTX 970 109200 Mtexels/sec
Difference: 402800 (369%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon Pro Duo is superior to the GeForce GTX 970, by far. (explain)

Radeon Pro Duo 128000 Mpixels/sec
GeForce GTX 970 67200 Mpixels/sec
Difference: 60800 (90%)

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 data (in units of MB per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses 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, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core 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 applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate 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 filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
