Radeon RX 590 vs Radeon RX Vega 64

Intro

The Radeon RX 590 has a clock speed of 1469 MHz and a GDDR5 memory frequency of 2000 MHz. It also makes use of a 256-bit bus, and uses a 12 nm design. It is made up of 2304 SPUs, 144 Texture Address Units, and 32 ROPs.

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 590 175 Watts
Radeon RX Vega 64 295 Watts
Difference: 120 Watts (69%)

Memory Bandwidth

As far as performance goes, the Radeon RX Vega 64 should theoretically be quite a bit superior to the Radeon RX 590 overall. (explain)

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

Texel Rate

The Radeon RX Vega 64 is quite a bit (about 51%) better at texture 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

If running with lots of anti-aliasing is important to you, then the Radeon RX Vega 64 is a better choice, and very much so. (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 max amount of data (measured in MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 can be applied per second. This is calculated by multiplying the total number 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
