Geforce GTX 1080 Ti vs Radeon Pro Duo

Intro

The Geforce GTX 1080 Ti features core speeds of 1480 MHz on the GPU, and 1376 MHz on the 11264 MB of GDDR5X RAM. It features 3584 SPUs along with 224 Texture Address Units and 88 Rasterization Operator Units.

Compare those specs to the Radeon Pro Duo, which has GPU core speed of 1000 MHz, and 4096 MB of HBM RAM set to run at 500 MHz through a 4096-bit bus. It also is made up of 4096 SPUs, 256 Texture Address Units, and 64 Raster Operation Units.

Memory Bandwidth

In theory, the Radeon Pro Duo should be 107% faster than the Geforce GTX 1080 Ti in general, due to its higher data rate. (explain)

Radeon Pro Duo 1024000 MB/sec
Geforce GTX 1080 Ti 495616 MB/sec
Difference: 528384 (107%)

Texel Rate

The Radeon Pro Duo will be quite a bit (more or less 54%) more effective at anisotropic filtering than the Geforce GTX 1080 Ti. (explain)

Radeon Pro Duo 512000 Mtexels/sec
Geforce GTX 1080 Ti 331520 Mtexels/sec
Difference: 180480 (54%)

Pixel Rate

The Geforce GTX 1080 Ti is a bit (about 2%) faster with regards to FSAA than the Radeon Pro Duo, and also will be able to handle higher screen resolutions without slowing down too much. (explain)

Geforce GTX 1080 Ti 130240 Mpixels/sec
Radeon Pro Duo 128000 Mpixels/sec
Difference: 2240 (2%)

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 largest amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
