Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6950 XT		335 Watts
Radeon RX 7900 XTX		355 Watts
	Difference: 20 Watts (6%)

Memory Bandwidth

In theory, the Radeon RX 7900 XTX is 67% faster than the Radeon RX 6950 XT overall, because of its higher data rate. (explain)

Radeon RX 7900 XTX		983040 MB/sec
Radeon RX 6950 XT		589824 MB/sec
	Difference: 393216 (67%)

Texel Rate

The Radeon RX 7900 XTX should be a little bit (approximately 16%) more effective at anisotropic filtering than the Radeon RX 6950 XT. (explain)

Radeon RX 7900 XTX		712320 Mtexels/sec
Radeon RX 6950 XT		616000 Mtexels/sec
	Difference: 96320 (16%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 7900 XTX is the winner, and very much so. (explain)

Radeon RX 7900 XTX		356160 Mpixels/sec
Radeon RX 6950 XT		246400 Mpixels/sec
	Difference: 109760 (45%)

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 megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units by the core 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 card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
