VS

Radeon RX 5700 XT vs Radeon RX 6800 XT

Intro

The Radeon RX 5700 XT has a core clock frequency of 1605 MHz and a GDDR6 memory speed of 1750 MHz. It also makes use of a 256-bit memory bus, and uses a 7 nm design. It is made up of 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

Compare those specifications to the Radeon RX 6800 XT, which has core clock speeds of 1825 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 memory. It features 4608 SPUs as well as 288 TAUs and 128 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700 XT 225 Watts
Radeon RX 6800 XT 300 Watts
Difference: 75 Watts (33%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6800 XT is 14% faster than the Radeon RX 5700 XT in general, due to its greater bandwidth. (explain)

Radeon RX 6800 XT 524288 MB/sec
Radeon RX 5700 XT 458752 MB/sec
Difference: 65536 (14%)

Texel Rate

The Radeon RX 6800 XT should be quite a bit (approximately 105%) better at AF than the Radeon RX 5700 XT. (explain)

Radeon RX 6800 XT 525600 Mtexels/sec
Radeon RX 5700 XT 256800 Mtexels/sec
Difference: 268800 (105%)

Pixel Rate

The Radeon RX 6800 XT is a lot (more or less 127%) more effective at anti-aliasing than the Radeon RX 5700 XT, and also will be capable of handling higher screen resolutions more effectively. (explain)

Radeon RX 6800 XT 233600 Mpixels/sec
Radeon RX 5700 XT 102720 Mpixels/sec
Difference: 130880 (127%)

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 max amount of data (counted in MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
