Radeon RX 6800 vs Radeon Vega Frontier Edition

Intro

Compare those specs to the Radeon Vega Frontier Edition, which features a GPU core clock speed of 1382 MHz, and 16384 MB of HBM2 RAM running at 1890 MHz through a 2048-bit bus. It also features 4096 SPUs, 256 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6800		250 Watts
Radeon Vega Frontier Edition		300 Watts
	Difference: 50 Watts (20%)

Memory Bandwidth

Performance-wise, the Radeon RX 6800 should in theory be a bit superior to the Radeon Vega Frontier Edition in general. (explain)

Radeon RX 6800		524288 MB/sec
Radeon Vega Frontier Edition		495452 MB/sec
	Difference: 28836 (6%)

Texel Rate

The Radeon RX 6800 is just a bit (more or less 15%) better at AF than the Radeon Vega Frontier Edition. (explain)

Radeon RX 6800		408000 Mtexels/sec
Radeon Vega Frontier Edition		353792 Mtexels/sec
	Difference: 54208 (15%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6800 is a better choice, and very much so. (explain)

Radeon RX 6800		163200 Mpixels/sec
Radeon Vega Frontier Edition		88448 Mpixels/sec
	Difference: 74752 (85%)

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 data (measured in megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics 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 most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
