Compare any two graphics cards:
VS

GeForce GTX 1070 vs Radeon RX 6600 XT

Intro

The GeForce GTX 1070 has a GPU core clock speed of 1506 MHz, and the 8192 MB of GDDR5 RAM runs at 2000 MHz through a 256-bit bus. It also features 1920 Stream Processors, 120 TAUs, and 64 ROPs.

Compare that to the Radeon RX 6600 XT, which comes with GPU core speed of 1968 MHz, and 8192 MB of GDDR6 RAM running at 2000 MHz through a 128-bit bus. It also is made up of 2048 Stream Processors, 128 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1070 150 Watts
Radeon RX 6600 XT 160 Watts
Difference: 10 Watts (7%)

Memory Bandwidth

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

Texel Rate

The Radeon RX 6600 XT will be a lot (approximately 39%) more effective at anisotropic filtering than the GeForce GTX 1070. (explain)

Radeon RX 6600 XT 251904 Mtexels/sec
GeForce GTX 1070 180720 Mtexels/sec
Difference: 71184 (39%)

Pixel Rate

The Radeon RX 6600 XT will be quite a bit (approximately 31%) more effective at full screen anti-aliasing than the GeForce GTX 1070, and should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 6600 XT 125952 Mpixels/sec
GeForce GTX 1070 96384 Mpixels/sec
Difference: 29568 (31%)

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: Bandwidth is the maximum amount of information (in units of MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the 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 video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
