Radeon RX 6800 XT vs Radeon Vega Frontier Edition

Intro

Compare all that to the Radeon Vega Frontier Edition, which features a core clock speed of 1382 MHz and a HBM2 memory frequency of 1890 MHz. It also features a 2048-bit memory bus, and uses a 14 nm design. It features 4096 SPUs, 256 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Radeon RX 6800 XT should be 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 much (more or less 49%) better 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 should be a lot (about 164%) better at AA than the Radeon Vega Frontier Edition, and will be capable of handling higher screen resolutions without slowing down too much. (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: Bandwidth is the max amount of information (measured in megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics 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 most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs 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 fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
