Radeon Pro Duo vs Radeon RX Vega 64

Intro

The Radeon Pro Duo has a clock speed of 1000 MHz and a HBM memory frequency of 500 MHz. It also features a 4096-bit memory bus, and makes use of a 28 nm design. It is made up of 4096 SPUs, 256 Texture Address Units, and 64 Raster Operation Units.

Compare those specs to the Radeon RX Vega 64, which uses a 14 nm design. AMD has set the core frequency at 1247 MHz. The HBM2 RAM runs at a speed of 1890 MHz on this particular model. It features 4096 SPUs as well as 256 Texture Address Units and 64 Rasterization Operator Units.

Memory Bandwidth

In theory, the Radeon Pro Duo should be 107% faster than the Radeon RX Vega 64 in general, because of its greater bandwidth. (explain)

Radeon Pro Duo 1024000 MB/sec
Radeon RX Vega 64 495411 MB/sec
Difference: 528589 (107%)

Texel Rate

The Radeon Pro Duo will be much (approximately 60%) more effective at AF than the Radeon RX Vega 64. (explain)

Radeon Pro Duo 512000 Mtexels/sec
Radeon RX Vega 64 319232 Mtexels/sec
Difference: 192768 (60%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon Pro Duo is the winner, and very much so. (explain)

Radeon Pro Duo 128000 Mpixels/sec
Radeon RX Vega 64 79808 Mpixels/sec
Difference: 48192 (60%)

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 max amount of information (in units of megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 processed in one 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 higher this number, the better the graphics card will be at 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 video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
