Radeon RX 5700 XT vs Radeon RX Vega 64

Intro

Compare that to the Radeon RX Vega 64, which has clock speeds of 1247 MHz on the GPU, and 1890 MHz on the 8192 MB of HBM2 memory. It features 4096 SPUs along with 256 Texture Address Units and 64 ROPs.

Power Consumption (Max TDP)

Radeon RX 5700 XT		225 Watts
Radeon RX Vega 64		295 Watts
	Difference: 70 Watts (31%)

Memory Bandwidth

The Radeon RX Vega 64 should theoretically perform a small bit faster than the Radeon RX 5700 XT in general. (explain)

Radeon RX Vega 64		495411 MB/sec
Radeon RX 5700 XT		458752 MB/sec
	Difference: 36659 (8%)

Texel Rate

The Radeon RX Vega 64 should be quite a bit (more or less 24%) better at anisotropic filtering than the Radeon RX 5700 XT. (explain)

Radeon RX Vega 64		319232 Mtexels/sec
Radeon RX 5700 XT		256800 Mtexels/sec
	Difference: 62432 (24%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 5700 XT is a better choice, by far. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
Radeon RX Vega 64		79808 Mpixels/sec
	Difference: 22912 (29%)

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: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
