Radeon RX 6900 XT vs Radeon Vega Frontier Edition

Intro

Compare that to the Radeon Vega Frontier Edition, which uses a 14 nm design. AMD has clocked the core frequency at 1382 MHz. The HBM2 RAM runs at a frequency of 1890 MHz on this specific model. It features 4096 SPUs along with 256 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Radeon RX 6900 XT should perform a bit faster than the Radeon Vega Frontier Edition overall. (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 will be a lot (about 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

The Radeon RX 6900 XT will be a lot (about 164%) more effective at full screen anti-aliasing than the Radeon Vega Frontier Edition, and should be capable of handling higher screen resolutions without slowing down too much. (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 max amount of data (counted in MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should 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 anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
