VS

Radeon RX 5700 XT 50th Anniversary Edition vs Radeon RX 6800

Intro

The Radeon RX 5700 XT 50th Anniversary Edition uses a 7 nm design. AMD has set the core speed at 1680 MHz. The GDDR6 memory runs at a frequency of 1750 MHz on this card. It features 2560 SPUs along with 160 TAUs and 64 ROPs.

Compare those specifications to the Radeon RX 6800, which features core clock speeds of 1700 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 memory. It features 3840 SPUs along with 240 Texture Address Units and 96 Rasterization Operator Units.

Radeon RX 5700 XT 50th Anniversary Edition 235 Watts
Radeon RX 6800 250 Watts
Difference: 15 Watts (6%)

Memory Bandwidth

Performance-wise, the Radeon RX 6800 should theoretically be a little bit superior to the Radeon RX 5700 XT 50th Anniversary Edition in general. (explain)

Radeon RX 6800 524288 MB/sec
Radeon RX 5700 XT 50th Anniversary Edition 458752 MB/sec
Difference: 65536 (14%)

Texel Rate

The Radeon RX 6800 should be much (about 52%) more effective at anisotropic filtering than the Radeon RX 5700 XT 50th Anniversary Edition. (explain)

Radeon RX 6800 408000 Mtexels/sec
Radeon RX 5700 XT 50th Anniversary Edition 268800 Mtexels/sec
Difference: 139200 (52%)

Pixel Rate

The Radeon RX 6800 should be a lot (more or less 52%) better at AA than the Radeon RX 5700 XT 50th Anniversary Edition, and should be able to handle higher resolutions better. (explain)

Radeon RX 6800 163200 Mpixels/sec
Radeon RX 5700 XT 50th Anniversary Edition 107520 Mpixels/sec
Difference: 55680 (52%)

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 largest amount of data (in units of MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling 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 record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). 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 maximum fill rate.
