Compare any two graphics cards:
Radeon R9 280X vs Radeon RX 6650 XT
IntroThe Radeon R9 280X comes with a GPU core clock speed of 850 MHz, and the 3072 MB of GDDR5 RAM runs at 1500 MHz through a 384-bit bus. It also is made up of 2048 Stream Processors, 128 Texture Address Units, and 32 ROPs.Compare those specifications to the Radeon RX 6650 XT, which features a clock frequency of 2055 MHz and a GDDR6 memory speed of 2190 MHz. It also makes use of a 128-bit memory bus, and makes use of a 7 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon R9 280X should in theory be a small bit better than the Radeon RX 6650 XT in general. (explain)
Texel RateThe Radeon RX 6650 XT should be quite a bit (approximately 142%) better at AF than the Radeon R9 280X. (explain)
Pixel RateThe Radeon RX 6650 XT will be much (about 384%) more effective at AA than the Radeon R9 280X, and able to handle 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 max amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
