Radeon R7 250		73600 MB/sec
	Difference: 155776 (212%)

Texel Rate

The Radeon RX 6600 will be much (about 659%) better at texture filtering than the Radeon R7 250. (explain)

Radeon RX 6600		182112 Mtexels/sec
Radeon R7 250		24000 Mtexels/sec
	Difference: 158112 (659%)

Pixel Rate

The Radeon RX 6600 is quite a bit (approximately 1201%) faster with regards to anti-aliasing than the Radeon R7 250, and also able to handle higher screen resolutions better. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon R7 250		8000 Mpixels/sec
	Difference: 96064 (1201%)

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 over the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure 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 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 figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
