Radeon RX 5600 vs Radeon RX 6800

Intro

The Radeon RX 5600 uses a 7 nm design. AMD has set the core speed at 1375 MHz. The GDDR6 RAM runs at a speed of 1500 MHz on this card. It features 2048 SPUs as well as 128 Texture Address Units and 64 Rasterization Operator Units.

Compare those specs to the Radeon RX 6800, which uses a 7 nm design. AMD has set the core speed at 1700 MHz. The GDDR6 memory is set to run at a frequency of 2000 MHz on this card. It features 3840 SPUs along with 240 TAUs and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600 150 Watts
Radeon RX 6800 250 Watts
Difference: 100 Watts (67%)

Memory Bandwidth

The Radeon RX 6800, in theory, should be much faster than the Radeon RX 5600 in general. (explain)

Radeon RX 6800 524288 MB/sec
Radeon RX 5600 294912 MB/sec
Difference: 229376 (78%)

Texel Rate

The Radeon RX 6800 is a lot (approximately 132%) better at texture filtering than the Radeon RX 5600. (explain)

Radeon RX 6800 408000 Mtexels/sec
Radeon RX 5600 176000 Mtexels/sec
Difference: 232000 (132%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6800 is the winner, and very much so. (explain)

Radeon RX 6800 163200 Mpixels/sec
Radeon RX 5600 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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses 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 high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
