Compare any two graphics cards:
Radeon R9 Nano vs Radeon RX 6800 XT
IntroThe Radeon R9 Nano makes use of a 28 nm design. AMD has clocked the core speed at 1000 MHz. The HBM RAM works at a speed of 500 MHz on this model. It features 4096 SPUs along with 256 Texture Address Units and 64 Rasterization Operator Units.Compare that to the Radeon RX 6800 XT, which uses a 7 nm design. AMD has clocked the core speed at 1825 MHz. The GDDR6 memory runs at a speed of 2000 MHz on this specific model. It features 4608 SPUs along with 288 TAUs and 128 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon RX 6800 XT is 2% quicker than the Radeon R9 Nano overall, because of its greater bandwidth. (explain)
Texel RateThe Radeon RX 6800 XT will be a lot (about 105%) better at anisotropic filtering than the Radeon R9 Nano. (explain)
Pixel RateThe Radeon RX 6800 XT is a lot (approximately 265%) more effective at FSAA than the Radeon R9 Nano, and should be able to handle higher screen 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: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 texture map elements (texels) that can be processed in one second. This figure is calculated 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its 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 - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
