Radeon RX 5600 vs Radeon RX Vega 64

Intro

Compare all that to the Radeon RX Vega 64, which uses a 14 nm design. AMD has set the core frequency at 1247 MHz. The HBM2 memory works at a speed of 1890 MHz on this specific card. It features 4096 SPUs along with 256 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600		150 Watts
Radeon RX Vega 64		295 Watts
	Difference: 145 Watts (97%)

Memory Bandwidth

As far as performance goes, the Radeon RX Vega 64 should in theory be a lot superior to the Radeon RX 5600 in general. (explain)

Radeon RX Vega 64		495411 MB/sec
Radeon RX 5600		294912 MB/sec
	Difference: 200499 (68%)

Texel Rate

The Radeon RX Vega 64 will be much (approximately 81%) more effective at texture filtering than the Radeon RX 5600. (explain)

Radeon RX Vega 64		319232 Mtexels/sec
Radeon RX 5600		176000 Mtexels/sec
	Difference: 143232 (81%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 5600 is a better choice, but it probably won't make a huge difference. (explain)

Radeon RX 5600		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: Memory bandwidth is the max amount of data (counted in MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the 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 amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video 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 chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated 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 outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
