Radeon RX 6800 XT vs Radeon Vega Frontier Edition

Intro

The Radeon RX 6800 XT comes with a GPU clock speed of 1825 MHz, and the 16384 MB of GDDR6 memory is set to run at 2000 MHz through a 256-bit bus. It also is comprised of 4608 Stream Processors, 288 Texture Address Units, and 128 Raster Operation Units.

Compare that to the Radeon Vega Frontier Edition, which makes use of a 14 nm design. AMD has clocked the core speed at 1382 MHz. The HBM2 memory works at a speed of 1890 MHz on this particular model. It features 4096 SPUs along with 256 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically, the Radeon RX 6800 XT should perform just a bit faster than the Radeon Vega Frontier Edition in general. (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 (about 49%) more effective 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 a high screen resolution 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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
