VS

Radeon RX 6800 XT vs Radeon Vega Frontier Edition

Intro

The Radeon RX 6800 XT features a GPU core clock speed of 1825 MHz, and the 16384 MB of GDDR6 RAM is set to run at 2000 MHz through a 256-bit bus. It also is comprised of 4608 SPUs, 288 TAUs, and 128 ROPs.

Compare all that to the Radeon Vega Frontier Edition, which uses a 14 nm design. AMD has clocked the core frequency at 1382 MHz. The HBM2 memory is set to run at a speed of 1890 MHz on this specific model. It features 4096 SPUs along with 256 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon RX 6800 XT should theoretically 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 is quite a bit (about 49%) more effective at texture 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

The Radeon RX 6800 XT will be much (approximately 164%) more effective at anti-aliasing than the Radeon Vega Frontier Edition, and able to handle higher screen resolutions better. (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 largest amount of data (measured in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 texture map elements (texels) that can be processed in one second. This is calculated 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
