Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6950 XT		335 Watts
Radeon R9 295X2		500 Watts
	Difference: 165 Watts (49%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 295X2 is 9% faster than the Radeon RX 6950 XT overall, due to its higher data rate. (explain)

Radeon R9 295X2		640000 MB/sec
Radeon RX 6950 XT		589824 MB/sec
	Difference: 50176 (9%)

Texel Rate

The Radeon RX 6950 XT is quite a bit (approximately 72%) better at anisotropic filtering than the Radeon R9 295X2. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
Radeon R9 295X2		358336 Mtexels/sec
	Difference: 257664 (72%)

Pixel Rate

The Radeon RX 6950 XT is a lot (more or less 89%) better at AA than the Radeon R9 295X2, and should be capable of handling higher screen resolutions more effectively. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
Radeon R9 295X2		130304 Mpixels/sec
	Difference: 116096 (89%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
