Compare any two graphics cards:
Radeon R9 280X vs Radeon RX 6650 XT
IntroThe Radeon R9 280X has a GPU 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 SPUs, 128 TAUs, and 32 Raster Operation Units.Compare those specifications to the Radeon RX 6650 XT, which features GPU core speed of 2055 MHz, and 8192 MB of GDDR6 memory running at 2190 MHz through a 128-bit bus. It also features 2048 Stream Processors, 128 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon R9 280X should in theory be a bit superior to the Radeon RX 6650 XT in general. (explain)
Texel RateThe Radeon RX 6650 XT should be a lot (more or less 142%) faster with regards to texture filtering than the Radeon R9 280X. (explain)
Pixel RateThe Radeon RX 6650 XT should be quite a bit (about 384%) faster with regards to AA than the Radeon R9 280X, and able to handle higher resolutions better. (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 information (counted in megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 per second. This number is worked out by multiplying the total number of texture units by the core 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 processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
