	Difference: 77 Watts (140%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6600 is 219% faster than the Radeon HD 7750 in general, because of its higher bandwidth. (explain)

Radeon RX 6600		229376 MB/sec
Radeon HD 7750		72000 MB/sec
	Difference: 157376 (219%)

Texel Rate

The Radeon RX 6600 should be much (approximately 611%) more effective at AF than the Radeon HD 7750. (explain)

Radeon RX 6600		182112 Mtexels/sec
Radeon HD 7750		25600 Mtexels/sec
	Difference: 156512 (611%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6600 is a better choice, by far. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon HD 7750		12800 Mpixels/sec
	Difference: 91264 (713%)

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 megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
