Compare any two graphics cards:
GeForce GTX 780 Ti vs Radeon RX 6650 XT
IntroThe GeForce GTX 780 Ti uses a 28 nm design. nVidia has set the core frequency at 875 MHz. The GDDR5 memory works at a speed of 1750 MHz on this card. It features 2880 SPUs along with 240 Texture Address Units and 48 Rasterization Operator Units.Compare all of that to the Radeon RX 6650 XT, which uses a 7 nm design. AMD has set the core frequency at 2055 MHz. The GDDR6 RAM runs at a speed of 2190 MHz on this card. It features 2048 SPUs as well as 128 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 780 Ti should theoretically be a bit better than the Radeon RX 6650 XT in general. (explain)
Texel RateThe Radeon RX 6650 XT will be quite a bit (about 25%) more effective at AF than the GeForce GTX 780 Ti. (explain)
Pixel RateThe Radeon RX 6650 XT should be quite a bit (about 213%) faster with regards to AA than the GeForce GTX 780 Ti, and will be capable of handling higher screen resolutions without losing too much performance. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated 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 processed per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
