Compare any two graphics cards:
GeForce GTX 660 vs Radeon RX 6500 XT
IntroThe GeForce GTX 660 has a core clock frequency of 980 MHz and a GDDR5 memory frequency of 1502 MHz. It also uses a 192-bit bus, and makes use of a 28 nm design. It is made up of 960 SPUs, 80 Texture Address Units, and 24 ROPs.Compare that to the Radeon RX 6500 XT, which has GPU core 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.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon RX 6500 XT will be 2% quicker than the GeForce GTX 660 in general, due to its higher data rate. (explain)
Texel RateThe Radeon RX 6500 XT should be a lot (approximately 80%) better at AF than the GeForce GTX 660. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon RX 6500 XT is a better choice, by far. (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 maximum amount of data (measured in MB per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 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 higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
