VS

Radeon RX 6800 XT vs Radeon Vega Frontier Edition

Intro

The Radeon RX 6800 XT makes use of a 7 nm design. AMD has set the core speed at 1825 MHz. The GDDR6 RAM is set to run at a speed of 2000 MHz on this model. It features 4608 SPUs as well as 288 Texture Address Units and 128 ROPs.

Compare those specs to the Radeon Vega Frontier Edition, which features core speeds of 1382 MHz on the GPU, and 1890 MHz on the 16384 MB of HBM2 memory. It features 4096 SPUs along with 256 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Radeon RX 6800 XT should perform just a bit faster than the Radeon Vega Frontier Edition overall. (explain)

Radeon RX 6800 XT 524288 MB/sec
Radeon Vega Frontier Edition 495452 MB/sec
Difference: 28836 (6%)

Texel Rate

The Radeon RX 6800 XT should be quite a bit (approximately 49%) better at anisotropic filtering than the Radeon Vega Frontier Edition. (explain)

Radeon RX 6800 XT 525600 Mtexels/sec
Radeon Vega Frontier Edition 353792 Mtexels/sec
Difference: 171808 (49%)

Pixel Rate

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

Radeon RX 6800 XT 233600 Mpixels/sec
Radeon Vega Frontier Edition 88448 Mpixels/sec
Difference: 145152 (164%)

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 information (measured in MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. 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 texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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