Radeon RX 6900 XT vs Radeon Vega Frontier Edition

Intro

Compare those specs to the Radeon Vega Frontier Edition, which makes use of a 14 nm design. AMD has set the core frequency at 1382 MHz. The HBM2 memory runs at a speed of 1890 MHz on this 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 is 6% quicker than the Radeon Vega Frontier Edition overall, because of its greater bandwidth. (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 quite a bit (approximately 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 is quite a bit (approximately 164%) faster with regards to full screen anti-aliasing than the Radeon Vega Frontier Edition, and should be able to handle 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 maximum amount of data (counted in MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses 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, High Dynamic Range and higher screen resolutions.

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

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