Geforce GTX 770 vs Radeon RX 5500 XT

Intro

Compare those specs to the Radeon RX 5500 XT, which features a clock speed of 1717 MHz and a GDDR6 memory speed of 1750 MHz. It also uses a 128-bit memory bus, and makes use of a 7 nm design. It features 1408 SPUs, 88 Texture Address Units, and 32 ROPs.

Geforce GTX 770		224384 MB/sec
	Difference: 4992 (2%)

Texel Rate

The Radeon RX 5500 XT should be a bit (approximately 13%) more effective at texture filtering than the Geforce GTX 770. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
Geforce GTX 770		133888 Mtexels/sec
	Difference: 17208 (13%)

Pixel Rate

The Radeon RX 5500 XT should be quite a bit (about 64%) better at full screen anti-aliasing than the Geforce GTX 770, and will be able to handle higher screen resolutions better. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
Geforce GTX 770		33472 Mpixels/sec
	Difference: 21472 (64%)

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 (in units of megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
