Compare any two graphics cards:
Radeon RX 580 vs Radeon RX 6650 XT
IntroThe Radeon RX 580 features a GPU core speed of 1257 MHz, and the 8192 MB of GDDR5 memory is set to run at 2000 MHz through a 256-bit bus. It also features 2304 SPUs, 144 TAUs, and 32 Raster Operation Units.Compare those specs to the Radeon RX 6650 XT, which has a core clock speed of 2055 MHz and a GDDR6 memory frequency of 2190 MHz. It also uses a 128-bit bus, and makes use of a 7 nm design. It features 2048 SPUs, 128 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon RX 6650 XT should perform a small bit faster than the Radeon RX 580 overall. (explain)
Texel RateThe Radeon RX 6650 XT should be quite a bit (approximately 45%) more effective at texture filtering than the Radeon RX 580. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon RX 6650 XT is superior to the Radeon RX 580, by a large margin. (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 max amount of information (in units of megabytes per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
