Compare any two graphics cards:
Radeon HD 7970 vs Radeon RX 6600 XT
IntroThe Radeon HD 7970 uses a 28 nm design. AMD has set the core frequency at 925 MHz. The GDDR5 memory runs at a frequency of 1375 MHz on this particular model. It features 2048 SPUs along with 128 TAUs and 32 ROPs.Compare all of that to the Radeon RX 6600 XT, which features a core clock speed of 1968 MHz and a GDDR6 memory frequency of 2000 MHz. It also makes use of a 128-bit memory bus, and makes use of a 7 nm design. It features 2048 SPUs, 128 TAUs, and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 7970 should in theory be just a bit superior to the Radeon RX 6600 XT in general. (explain)
Texel RateThe Radeon RX 6600 XT will be quite a bit (approximately 113%) better at AF than the Radeon HD 7970. (explain)
Pixel RateThe Radeon RX 6600 XT will be a lot (about 326%) more effective at FSAA than the Radeon HD 7970, and also capable of handling 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: Bandwidth is the max amount of data (in units of megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 are applied per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
