Radeon RX 6800 XT vs Radeon RX 6950 XT

Intro

Compare all of that to the Radeon RX 6950 XT, which has GPU clock speed of 1925 MHz, and 16384 MB of GDDR6 RAM running at 2250 MHz through a 256-bit bus. It also is comprised of 5120 Stream Processors, 320 TAUs, and 128 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6800 XT		300 Watts
Radeon RX 6950 XT		335 Watts
	Difference: 35 Watts (12%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6950 XT will be 13% quicker than the Radeon RX 6800 XT overall, due to its greater bandwidth. (explain)

Radeon RX 6950 XT		589824 MB/sec
Radeon RX 6800 XT		524288 MB/sec
	Difference: 65536 (13%)

Texel Rate

The Radeon RX 6950 XT should be a small bit (approximately 17%) more effective at AF than the Radeon RX 6800 XT. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
Radeon RX 6800 XT		525600 Mtexels/sec
	Difference: 90400 (17%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 6950 XT is a better choice, but not by far. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
Radeon RX 6800 XT		233600 Mpixels/sec
	Difference: 12800 (5%)

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 information (counted in megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
