Radeon RX 6600 XT		160 Watts
Radeon R9 295X2		500 Watts
	Difference: 340 Watts (213%)

Memory Bandwidth

The Radeon R9 295X2, in theory, should be quite a bit faster than the Radeon RX 6600 XT in general. (explain)

Radeon R9 295X2		640000 MB/sec
Radeon RX 6600 XT		262144 MB/sec
	Difference: 377856 (144%)

Texel Rate

The Radeon R9 295X2 should be much (approximately 42%) faster with regards to anisotropic filtering than the Radeon RX 6600 XT. (explain)

Radeon R9 295X2		358336 Mtexels/sec
Radeon RX 6600 XT		251904 Mtexels/sec
	Difference: 106432 (42%)

Pixel Rate

The Radeon R9 295X2 is a little bit (about 3%) more effective at FSAA than the Radeon RX 6600 XT, and will be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon R9 295X2		130304 Mpixels/sec
Radeon RX 6600 XT		125952 Mpixels/sec
	Difference: 4352 (3%)

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 maximum amount of information (in units of MB per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 maximum amount of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
