Radeon RX 7900 XT vs Radeon Vega Frontier Edition

Intro

Compare those specifications to the Radeon Vega Frontier Edition, which has core clock speeds of 1382 MHz on the GPU, and 1890 MHz on the 16384 MB of HBM2 RAM. It features 4096 SPUs along with 256 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Radeon RX 7900 XT is 65% faster than the Radeon Vega Frontier Edition overall, because of its higher data rate. (explain)

Radeon RX 7900 XT		819200 MB/sec
Radeon Vega Frontier Edition		495452 MB/sec
	Difference: 323748 (65%)

Texel Rate

The Radeon RX 7900 XT will be quite a bit (about 42%) better at texture filtering than the Radeon Vega Frontier Edition. (explain)

Radeon RX 7900 XT		504000 Mtexels/sec
Radeon Vega Frontier Edition		353792 Mtexels/sec
	Difference: 150208 (42%)

Pixel Rate

The Radeon RX 7900 XT is quite a bit (about 226%) more effective at anti-aliasing than the Radeon Vega Frontier Edition, and capable of handling higher resolutions while still performing well. (explain)

Radeon RX 7900 XT		288000 Mpixels/sec
Radeon Vega Frontier Edition		88448 Mpixels/sec
	Difference: 199552 (226%)

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 largest amount of data (measured in MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
