Radeon RX 6800 XT vs Radeon Vega Frontier Edition

Intro

The Radeon RX 6800 XT has a clock frequency of 1825 MHz and a GDDR6 memory speed of 2000 MHz. It also features a 256-bit memory bus, and uses a 7 nm design. It features 4608 SPUs, 288 Texture Address Units, and 128 ROPs.

Compare all of that to the Radeon Vega Frontier Edition, which features core speeds of 1382 MHz on the GPU, and 1890 MHz on the 16384 MB of HBM2 RAM. It features 4096 SPUs as well as 256 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Radeon RX 6800 XT will be 6% quicker than the Radeon Vega Frontier Edition overall, due to its greater bandwidth. (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 quite a bit (approximately 49%) more effective 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 will be a lot (approximately 164%) more effective at full screen anti-aliasing than the Radeon Vega Frontier Edition, and also should be capable of handling higher screen resolutions more effectively. (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.

Memory Bandwidth: 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 interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the 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 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 clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
