Compare any two graphics cards:
Radeon HD 7970 vs Radeon RX 6650 XT
IntroThe Radeon HD 7970 features a GPU core clock speed of 925 MHz, and the 3072 MB of GDDR5 memory is set to run at 1375 MHz through a 384-bit bus. It also is made up of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.Compare those specifications to the Radeon RX 6650 XT, which uses a 7 nm design. AMD has set the core frequency at 2055 MHz. The GDDR6 RAM runs at a frequency of 2190 MHz on this card. It features 2048 SPUs as well as 128 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon RX 6650 XT should in theory be a bit faster than the Radeon HD 7970 in general. (explain)
Texel RateThe Radeon RX 6650 XT is quite a bit (more or less 122%) faster with regards to AF than the Radeon HD 7970. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon RX 6650 XT is superior to the Radeon HD 7970, 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 max amount of data (measured in MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
