Compare any two graphics cards:
GeForce RTX 4080 vs Radeon RX 7900 XT
IntroThe GeForce RTX 4080 has a GPU core clock speed of 2205 MHz, and the 16384 MB of GDDR6X RAM runs at 1400 MHz through a 256-bit bus. It also is made up of 9728 Stream Processors, 304 TAUs, and 112 ROPs.Compare all of that to the Radeon RX 7900 XT, which makes use of a 5 nm design. AMD has set the core speed at 1500 MHz. The GDDR6 RAM is set to run at a speed of 2500 MHz on this card. It features 5376 SPUs along with 336 TAUs and 192 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon RX 7900 XT should be 12% quicker than the GeForce RTX 4080 in general, because of its greater bandwidth. (explain)
Texel RateThe GeForce RTX 4080 will be a lot (approximately 33%) faster with regards to AF than the Radeon RX 7900 XT. (explain)
Pixel RateThe Radeon RX 7900 XT is a little bit (about 17%) more effective at AA than the GeForce RTX 4080, and 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: Bandwidth is the max amount of information (measured in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, the result 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 AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied 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 figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
