Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the Radeon RX 6700 XT is 23% faster than the Radeon R9 290X overall, due to its higher data rate. (explain)

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

Texel Rate

The Radeon RX 6700 XT should be quite a bit (more or less 164%) faster with regards to anisotropic filtering than the Radeon R9 290X. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
Radeon R9 290X		140800 Mtexels/sec
	Difference: 230560 (164%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6700 XT is a better choice, by a large margin. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
Radeon R9 290X		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 across the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
