Compare any two graphics cards:
Radeon HD 7870 XT vs Radeon RX 6600
IntroThe Radeon HD 7870 XT makes use of a 28 nm design. AMD has set the core frequency at 925 MHz. The GDDR5 memory runs at a speed of 1500 MHz on this specific card. It features 1536 SPUs as well as 96 TAUs and 32 Rasterization Operator Units.Compare all that to the Radeon RX 6600, which comes with a clock frequency of 1626 MHz and a GDDR6 memory frequency of 1750 MHz. It also makes use of a 128-bit bus, and makes use of a 7 nm design. It is made up of 1792 SPUs, 112 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon RX 6600 will be 19% quicker than the Radeon HD 7870 XT in general, because of its greater data rate. (explain)
Texel RateThe Radeon RX 6600 will be much (more or less 105%) more effective at AF than the Radeon HD 7870 XT. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon RX 6600 is the winner, 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 maximum amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units of the card 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 in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one 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 clock speed. 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 memory bandwidth is, the lower the potential to reach the max fill rate.
