Radeon RX 6800 XT vs Radeon Vega Frontier Edition

Intro

Compare those specs to the Radeon Vega Frontier Edition, which uses a 14 nm design. AMD has set the core frequency at 1382 MHz. The HBM2 memory works at a frequency of 1890 MHz on this particular card. It features 4096 SPUs as well as 256 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Performance-wise, the Radeon RX 6800 XT should theoretically be a small bit superior to 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 is much (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 using lots of anti-aliasing is important to you, then the Radeon RX 6800 XT is the winner, and very much so. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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 of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
