Compare any two graphics cards:
Radeon R9 390 8G vs Radeon RX 6700 XT
IntroThe Radeon R9 390 8G has a GPU core clock speed of 1000 MHz, and the 8192 MB of GDDR5 RAM runs at 1500 MHz through a 512-bit bus. It also is comprised of 2560 SPUs, 160 TAUs, and 64 Raster Operation Units.Compare those specifications to the Radeon RX 6700 XT, which has clock speeds of 2321 MHz on the GPU, and 2000 MHz on the (Unknown) MB of GDDR6 RAM. It features 2560 SPUs as well as 160 Texture Address Units and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon RX 6700 XT should be 2% faster than the Radeon R9 390 8G overall, due to its greater data rate. (explain)
Texel RateThe Radeon RX 6700 XT should be much (about 132%) more effective at texture filtering than the Radeon R9 390 8G. (explain)
Pixel RateThe Radeon RX 6700 XT will be quite a bit (about 132%) faster with regards to full screen anti-aliasing than the Radeon R9 390 8G, and also should be able to handle higher resolutions better. (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 information (in units of megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units 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 maximum number of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
