Radeon RX 6800 XT vs Radeon Vega Frontier Edition

Intro

Compare those specifications to the Radeon Vega Frontier Edition, which has GPU clock speed of 1382 MHz, and 16384 MB of HBM2 RAM running at 1890 MHz through a 2048-bit bus. It also is made up of 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

As far as performance goes, the Radeon RX 6800 XT should in theory be a small bit superior to 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 will be quite a bit (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

If running with high levels of AA is important to you, then the Radeon RX 6800 XT is superior to the Radeon Vega Frontier Edition, 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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 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 high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
