Compare any two graphics cards:
Radeon RX 6800 vs Radeon RX 6900 XT
IntroThe Radeon RX 6800 has a clock frequency of 1700 MHz and a GDDR6 memory speed of 2000 MHz. It also makes use of a 256-bit memory bus, and makes use of a 7 nm design. It is made up of 3840 SPUs, 240 TAUs, and 96 ROPs.Compare that to the Radeon RX 6900 XT, which has core clock speeds of 1825 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 memory. It features 5120 SPUs as well as 320 TAUs and 128 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have exactly the same bandwidth, so theoretically they should perform exactly the same. (explain)
Texel RateThe Radeon RX 6900 XT is a lot (more or less 43%) faster with regards to anisotropic filtering than the Radeon RX 6800. (explain)
Pixel RateThe Radeon RX 6900 XT will be a lot (about 43%) better at full screen anti-aliasing than the Radeon RX 6800, and also able to handle higher resolutions without losing too much performance. (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 max amount of data (counted in megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
