Radeon R7 250X 2GB		95 Watts
Radeon RX 6950 XT		335 Watts
	Difference: 240 Watts (253%)

Memory Bandwidth

As far as performance goes, the Radeon RX 6950 XT should theoretically be quite a bit superior to the Radeon R7 250X 2GB overall. (explain)

Radeon RX 6950 XT		589824 MB/sec
Radeon R7 250X 2GB		72000 MB/sec
	Difference: 517824 (719%)

Texel Rate

The Radeon RX 6950 XT is quite a bit (more or less 1440%) faster with regards to anisotropic filtering than the Radeon R7 250X 2GB. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 576000 (1440%)

Pixel Rate

The Radeon RX 6950 XT is quite a bit (approximately 1440%) faster with regards to anti-aliasing than the Radeon R7 250X 2GB, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
Radeon R7 250X 2GB		16000 Mpixels/sec
	Difference: 230400 (1440%)

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: Bandwidth is the max amount of data (counted in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 can be applied in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher 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 most pixels the graphics card could possibly record 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 speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
