Geforce GTX 770		224384 MB/sec
	Difference: 62688 (28%)

Texel Rate

The Radeon RX 6650 XT is quite a bit (about 96%) more effective at anisotropic filtering than the Geforce GTX 770. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
Geforce GTX 770		133888 Mtexels/sec
	Difference: 129152 (96%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6650 XT is the winner, by far. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
Geforce GTX 770		33472 Mpixels/sec
	Difference: 98048 (293%)

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 information (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
