Radeon Pro Duo vs Radeon RX Vega 64

Intro

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

Compare those specifications to the Radeon RX Vega 64, which has GPU clock speed of 1247 MHz, and 8192 MB of HBM2 RAM set to run at 1890 MHz through a 2048-bit bus. It also features 4096 Stream Processors, 256 TAUs, and 64 Raster Operation Units.

Memory Bandwidth

In theory, the Radeon Pro Duo is 107% faster than the Radeon RX Vega 64 overall, because of its greater data rate. (explain)

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

Texel Rate

The Radeon Pro Duo should be a lot (about 60%) more effective at anisotropic filtering 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

The Radeon Pro Duo should be much (approximately 60%) better at AA than the Radeon RX Vega 64, and also should be capable of handling higher resolutions while still performing well. (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 maximum amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling 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 could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. 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 also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
