Radeon RX 6900 XT vs Radeon Vega Frontier Edition

Intro

Compare all that to the Radeon Vega Frontier Edition, which features a core clock frequency of 1382 MHz and a HBM2 memory speed of 1890 MHz. It also features a 2048-bit bus, and uses a 14 nm design. It 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

The Radeon RX 6900 XT, in theory, should be a little bit faster than 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 is a lot (approximately 65%) better 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 using a high screen resolution is important to you, then the Radeon RX 6900 XT is superior to the Radeon Vega Frontier Edition, and very much so. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the 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 most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 potential to reach the maximum fill rate.
