Compare any two graphics cards:
GeForce GTX 660 vs Radeon RX 6500 XT
IntroThe GeForce GTX 660 features a GPU core speed of 980 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1502 MHz through a 192-bit bus. It also features 960 SPUs, 80 Texture Address Units, and 24 Raster Operation Units.Compare that to the Radeon RX 6500 XT, which uses a 6 nm design. AMD has set the core speed at 2200 MHz. The GDDR6 memory works at a speed of 2250 MHz on this particular model. It features 1024 SPUs along with 64 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon RX 6500 XT should be a little bit faster than the GeForce GTX 660 in general. (explain)
Texel RateThe Radeon RX 6500 XT should be quite a bit (about 80%) more effective at texture filtering than the GeForce GTX 660. (explain)
Pixel RateThe Radeon RX 6500 XT will be a lot (more or less 199%) better at full screen anti-aliasing than the GeForce GTX 660, and will be capable of handling higher 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 maximum amount of data (in units of MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total amount of texture units by the core 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 per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
