Radeon RX 6800 XT vs Radeon Vega Frontier Edition

Intro

Compare those specifications to the Radeon Vega Frontier Edition, which has a clock frequency of 1382 MHz and a HBM2 memory frequency of 1890 MHz. It also uses a 2048-bit memory bus, and makes use of a 14 nm design. It is made up of 4096 SPUs, 256 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Radeon RX 6800 XT should be 6% faster than the Radeon Vega Frontier Edition in general, because of its greater data rate. (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 will be much (approximately 49%) faster with regards to AF 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 a better choice, by far. (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 largest amount of information (in units of MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write 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 the core 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 many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
