GeForce GTX 950		90 Watts
Radeon RX 7900 XT		300 Watts
	Difference: 210 Watts (233%)

Memory Bandwidth

In theory, the Radeon RX 7900 XT will be 675% quicker than the GeForce GTX 950 overall, due to its greater data rate. (explain)

Radeon RX 7900 XT		819200 MB/sec
GeForce GTX 950		105728 MB/sec
	Difference: 713472 (675%)

Texel Rate

The Radeon RX 7900 XT is quite a bit (more or less 925%) more effective at anisotropic filtering than the GeForce GTX 950. (explain)

Radeon RX 7900 XT		504000 Mtexels/sec
GeForce GTX 950		49152 Mtexels/sec
	Difference: 454848 (925%)

Pixel Rate

The Radeon RX 7900 XT will be a lot (more or less 779%) faster with regards to AA than the GeForce GTX 950, and capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 7900 XT		288000 Mpixels/sec
GeForce GTX 950		32768 Mpixels/sec
	Difference: 255232 (779%)

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 maximum amount of information (in units of megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must 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 AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. 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 fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
