Radeon RX 590 vs Radeon RX Vega 64

Intro

The Radeon RX 590 uses a 12 nm design. AMD has clocked the core frequency at 1469 MHz. The GDDR5 memory is set to run at a speed of 2000 MHz on this card. It features 2304 SPUs as well as 144 Texture Address Units and 32 ROPs.

Compare all of that to the Radeon RX Vega 64, which features a core clock frequency of 1247 MHz and a HBM2 memory speed of 1890 MHz. It also uses a 2048-bit memory bus, and makes use of a 14 nm design. It is comprised of 4096 SPUs, 256 TAUs, and 64 ROPs.

Radeon RX Vega 64 495411 MB/sec
Radeon RX 590 262144 MB/sec
Difference: 233267 (89%)

Texel Rate

The Radeon RX Vega 64 will be much (about 51%) faster with regards to anisotropic filtering than the Radeon RX 590. (explain)

Radeon RX Vega 64 319232 Mtexels/sec
Radeon RX 590 211536 Mtexels/sec
Difference: 107696 (51%)

Pixel Rate

The Radeon RX Vega 64 will be a lot (more or less 70%) faster with regards to AA than the Radeon RX 590, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX Vega 64 79808 Mpixels/sec
Radeon RX 590 47008 Mpixels/sec
Difference: 32800 (70%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics 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 that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
