Geforce GTX 770 vs Radeon RX 6500 XT

Intro

Compare all of that to the Radeon RX 6500 XT, which comes with GPU clock speed of 2200 MHz, and 4096 MB of GDDR6 memory running at 2250 MHz through a 64-bit bus. It also features 1024 SPUs, 64 Texture Address Units, and 32 ROPs.

Radeon RX 6500 XT		147456 MB/sec
	Difference: 76928 (52%)

Texel Rate

The Radeon RX 6500 XT is a little bit (approximately 5%) more effective at AF than the Geforce GTX 770. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
Geforce GTX 770		133888 Mtexels/sec
	Difference: 6912 (5%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 6500 XT is the winner, and very much so. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
Geforce GTX 770		33472 Mpixels/sec
	Difference: 36928 (110%)

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 maximum amount of data (in units of megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the 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 number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
