Compare any two graphics cards:
VS

Radeon RX 6900 XT vs Radeon Vega Frontier Edition

Intro

The Radeon RX 6900 XT has core clock speeds of 1825 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 memory. It features 5120 SPUs as well as 320 Texture Address Units and 128 ROPs.

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

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Performance-wise, the Radeon RX 6900 XT should theoretically be a small bit superior to the Radeon Vega Frontier Edition in general. (explain)

Radeon RX 6900 XT 524288 MB/sec
Radeon Vega Frontier Edition 495452 MB/sec
Difference: 28836 (6%)

Texel Rate

The Radeon RX 6900 XT should be quite a bit (more or less 65%) more effective at anisotropic filtering than the Radeon Vega Frontier Edition. (explain)

Radeon RX 6900 XT 584000 Mtexels/sec
Radeon Vega Frontier Edition 353792 Mtexels/sec
Difference: 230208 (65%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 6900 XT is superior to the Radeon Vega Frontier Edition, by a large margin. (explain)

Radeon RX 6900 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 max amount of information (counted in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's 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 fill rate also depends 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.
