Geforce GTX 770 vs Radeon RX 6600 XT

Intro

Compare those specifications to the Radeon RX 6600 XT, which makes use of a 7 nm design. AMD has clocked the core speed at 1968 MHz. The GDDR6 memory works at a speed of 2000 MHz on this specific model. It features 2048 SPUs along with 128 TAUs and 64 Rasterization Operator Units.

Geforce GTX 770		224384 MB/sec
	Difference: 37760 (17%)

Texel Rate

The Radeon RX 6600 XT is a lot (about 88%) more effective at anisotropic filtering than the Geforce GTX 770. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
Geforce GTX 770		133888 Mtexels/sec
	Difference: 118016 (88%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6600 XT is the winner, by far. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Geforce GTX 770		33472 Mpixels/sec
	Difference: 92480 (276%)

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 largest amount of information (counted in MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
