Compare any two graphics cards:
Radeon R9 390 8G vs Radeon RX 6700 XT
IntroThe Radeon R9 390 8G uses a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 RAM is set to run at a frequency of 1500 MHz on this particular model. It features 2560 SPUs as well as 160 Texture Address Units and 64 Rasterization Operator Units.Compare those specs to the Radeon RX 6700 XT, which comes with a core clock frequency of 2321 MHz and a GDDR6 memory speed of 2000 MHz. It also uses a 192-bit memory bus, and makes use of a 7 nm design. It is made up of 2560 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon RX 6700 XT should be a bit faster than the Radeon R9 390 8G in general. (explain)
Texel RateThe Radeon RX 6700 XT will be a lot (more or less 132%) faster with regards to AF than the Radeon R9 390 8G. (explain)
Pixel RateThe Radeon RX 6700 XT will be quite a bit (approximately 132%) faster with regards to AA than the Radeon R9 390 8G, and able to handle higher resolutions while still performing well. (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 maximum amount of information (in units of MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units 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 lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
