Compare any two graphics cards:
Radeon HD 7970 vs Radeon RX 6650 XT
IntroThe Radeon HD 7970 makes use of a 28 nm design. AMD has clocked the core speed at 925 MHz. The GDDR5 memory works at a frequency of 1375 MHz on this particular model. It features 2048 SPUs along with 128 TAUs and 32 ROPs.Compare all that to the Radeon RX 6650 XT, which makes use of a 7 nm design. AMD has clocked the core speed at 2055 MHz. The GDDR6 RAM runs at a frequency of 2190 MHz on this particular model. 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 BandwidthTheoretically, the Radeon RX 6650 XT should be a small bit faster than the Radeon HD 7970 overall. (explain)
Texel RateThe Radeon RX 6650 XT will be a lot (more or less 122%) faster with regards to AF than the Radeon HD 7970. (explain)
Pixel RateThe Radeon RX 6650 XT will be much (more or less 344%) faster with regards to FSAA than the Radeon HD 7970, and also able to handle higher resolutions more effectively. (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 largest amount of data (in units of MB per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the interface 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 better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount 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 applied per second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
