Radeon RX 5600 XT vs Radeon RX Vega 64

Intro

Compare all of that to the Radeon RX Vega 64, which features clock speeds of 1247 MHz on the GPU, and 1890 MHz on the 8192 MB of HBM2 memory. It features 4096 SPUs as well as 256 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600 XT		160 Watts
Radeon RX Vega 64		295 Watts
	Difference: 135 Watts (84%)

Memory Bandwidth

Theoretically speaking, the Radeon RX Vega 64 should be much faster than the Radeon RX 5600 XT in general. (explain)

Radeon RX Vega 64		495411 MB/sec
Radeon RX 5600 XT		344064 MB/sec
	Difference: 151347 (44%)

Texel Rate

The Radeon RX Vega 64 is quite a bit (more or less 61%) more effective at anisotropic filtering than the Radeon RX 5600 XT. (explain)

Radeon RX Vega 64		319232 Mtexels/sec
Radeon RX 5600 XT		198000 Mtexels/sec
	Difference: 121232 (61%)

Pixel Rate

The Radeon RX 5600 XT is just a bit (more or less 10%) more effective at anti-aliasing than the Radeon RX Vega 64, and should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
Radeon RX Vega 64		79808 Mpixels/sec
	Difference: 8192 (10%)

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 max amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called 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, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
