VS

Radeon RX 5600 vs Radeon RX 6800

Intro

The Radeon RX 5600 comes with core speeds of 1375 MHz on the GPU, and 1500 MHz on the 6144 MB of GDDR6 memory. It features 2048 SPUs along with 128 TAUs and 64 ROPs.

Compare all that to the Radeon RX 6800, which makes use of a 7 nm design. AMD has set the core speed at 1700 MHz. The GDDR6 memory runs at a frequency of 2000 MHz on this card. It features 3840 SPUs along with 240 Texture Address Units and 96 ROPs.

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

Theoretically speaking, the Radeon RX 6800 should be 78% faster than the Radeon RX 5600 overall, due to its greater bandwidth. (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 (more or less 132%) faster with regards to anisotropic 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 high levels of AA is important to you, then the Radeon RX 6800 is a better choice, 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: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the 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 maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. 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 lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
