Compare any two graphics cards:
VS

GeForce GTX 1070 Ti vs Radeon RX 6600 XT

Intro

The GeForce GTX 1070 Ti comes with core clock speeds of 1607 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 RAM. It features 2432 SPUs as well as 152 Texture Address Units and 64 Rasterization Operator Units.

Compare that to the Radeon RX 6600 XT, which comes with a clock frequency of 1968 MHz and a GDDR6 memory frequency of 2000 MHz. It also uses a 128-bit bus, and uses a 7 nm design. It features 2048 SPUs, 128 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600 XT 160 Watts
GeForce GTX 1070 Ti 180 Watts
Difference: 20 Watts (13%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so theoretically they should perform exactly the same. (explain)

Texel Rate

The Radeon RX 6600 XT will be just a bit (about 3%) more effective at anisotropic filtering than the GeForce GTX 1070 Ti. (explain)

Radeon RX 6600 XT 251904 Mtexels/sec
GeForce GTX 1070 Ti 244264 Mtexels/sec
Difference: 7640 (3%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6600 XT is superior to the GeForce GTX 1070 Ti, and very much so. (explain)

Radeon RX 6600 XT 125952 Mpixels/sec
GeForce GTX 1070 Ti 102848 Mpixels/sec
Difference: 23104 (22%)

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.

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write 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 card's clock speed. 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 also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
