Radeon RX 7900 XT vs Radeon Vega Frontier Edition

Intro

Compare all of that to the Radeon Vega Frontier Edition, which has GPU clock speed of 1382 MHz, and 16384 MB of HBM2 memory running at 1890 MHz through a 2048-bit bus. It also is comprised 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

Theoretically speaking, the Radeon RX 7900 XT should be a lot faster than the Radeon Vega Frontier Edition overall. (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 should be much (approximately 42%) faster with regards to anisotropic 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 a lot (approximately 226%) better at FSAA than the Radeon Vega Frontier Edition, and able to handle higher screen resolutions without losing too much performance. (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 information (in units of MB per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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