Radeon RX 6700 XT		230 Watts
Radeon R9 290		300 Watts
	Difference: 70 Watts (30%)

Memory Bandwidth

In theory, the Radeon RX 6700 XT should be a lot faster than the Radeon R9 290 in general. (explain)

Radeon RX 6700 XT		393216 MB/sec
Radeon R9 290		320000 MB/sec
	Difference: 73216 (23%)

Texel Rate

The Radeon RX 6700 XT will be quite a bit (approximately 190%) more effective at texture filtering than the Radeon R9 290. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
Radeon R9 290		128000 Mtexels/sec
	Difference: 243360 (190%)

Pixel Rate

The Radeon RX 6700 XT should be a lot (more or less 190%) better at AA than the Radeon R9 290, and also capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
Radeon R9 290		51200 Mpixels/sec
	Difference: 97344 (190%)

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 data (in units of megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 are applied per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card 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 - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
