Radeon RX 6800 vs Radeon RX 6950 XT

Intro

Compare those specifications to the Radeon RX 6950 XT, which features GPU core speed of 1925 MHz, and 16384 MB of GDDR6 RAM running at 2250 MHz through a 256-bit bus. It also is made up of 5120 Stream Processors, 320 TAUs, and 128 Raster Operation Units.

Radeon RX 6800		524288 MB/sec
	Difference: 65536 (13%)

Texel Rate

The Radeon RX 6950 XT will be quite a bit (about 51%) faster with regards to AF than the Radeon RX 6800. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
Radeon RX 6800		408000 Mtexels/sec
	Difference: 208000 (51%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 6950 XT is a better choice, and very much so. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
Radeon RX 6800		163200 Mpixels/sec
	Difference: 83200 (51%)

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 (measured in megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock 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 output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
