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 will be 9% quicker than the Radeon RX 6950 XT in general, due to its greater bandwidth. (explain)

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

Texel Rate

The Radeon RX 6950 XT should be quite a bit (more or less 72%) faster with regards to AF 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 will be much (about 89%) more effective at full screen anti-aliasing than the Radeon R9 295X2, and able to handle higher screen resolutions without slowing down too much. (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: Bandwidth is the max amount of data (measured in megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core 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 is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
