Radeon RX 5600 XT vs Radeon RX 6800

Intro

Compare all that to the Radeon RX 6800, which features a core clock speed of 1700 MHz and a GDDR6 memory frequency of 2000 MHz. It also uses a 256-bit bus, and uses a 7 nm design. It features 3840 SPUs, 240 TAUs, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600 XT		160 Watts
Radeon RX 6800		250 Watts
	Difference: 90 Watts (56%)

Memory Bandwidth

In theory, the Radeon RX 6800 is 52% faster than the Radeon RX 5600 XT overall, due to its higher data rate. (explain)

Radeon RX 6800		524288 MB/sec
Radeon RX 5600 XT		344064 MB/sec
	Difference: 180224 (52%)

Texel Rate

The Radeon RX 6800 should be quite a bit (about 106%) better at anisotropic filtering than the Radeon RX 5600 XT. (explain)

Radeon RX 6800		408000 Mtexels/sec
Radeon RX 5600 XT		198000 Mtexels/sec
	Difference: 210000 (106%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6800 is the winner, by far. (explain)

Radeon RX 6800		163200 Mpixels/sec
Radeon RX 5600 XT		88000 Mpixels/sec
	Difference: 75200 (85%)

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 largest amount of data (in units of MB per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called 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 memory bandwidth is, the lower the ability to get to the max fill rate.
