Compare any two graphics cards:
GeForce RTX 4090 vs Radeon RX 7900 XTX
IntroThe GeForce RTX 4090 has a GPU core clock speed of 2235 MHz, and the 24576 MB of GDDR6X RAM is set to run at 1325 MHz through a 384-bit bus. It also features 16384 SPUs, 512 TAUs, and 176 ROPs.Compare all of that to the Radeon RX 7900 XTX, which features a GPU core clock speed of 1855 MHz, and 24576 MB of GDDR6 RAM running at 2500 MHz through a 384-bit bus. It also features 6144 SPUs, 384 Texture Address Units, and 192 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce RTX 4090 should be 6% faster than the Radeon RX 7900 XTX in general, because of its greater data rate. (explain)
Texel RateThe GeForce RTX 4090 will be quite a bit (approximately 61%) more effective at anisotropic filtering than the Radeon RX 7900 XTX. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce RTX 4090 is the winner, but it probably won't make a huge difference. (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 data (in units of MB per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
