Radeon RX 590 vs Radeon RX Vega 64

Intro

Compare all of that to the Radeon RX Vega 64, which has GPU core speed of 1247 MHz, and 8192 MB of HBM2 RAM running at 1890 MHz through a 2048-bit bus. It also is made up of 4096 SPUs, 256 Texture Address Units, and 64 ROPs.

Memory Bandwidth

Performance-wise, the Radeon RX Vega 64 should in theory be much superior to the Radeon RX 590 in general. (explain)

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%) better at AF 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 using a high resolution is important to you, then the Radeon RX Vega 64 is the winner, by a large margin. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the 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 maximum amount of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also 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 bandwidth is, the lower the ability to get to the max fill rate.
