Compare any two graphics cards:
GeForce RTX 4080 vs GeForce RTX 4090
IntroThe GeForce RTX 4080 features core speeds of 2205 MHz on the GPU, and 1400 MHz on the 16384 MB of GDDR6X RAM. It features 9728 SPUs as well as 304 TAUs and 112 ROPs.Compare all of that to the GeForce RTX 4090, which features core speeds of 2235 MHz on the GPU, and 1325 MHz on the 24576 MB of GDDR6X RAM. It features 16384 SPUs as well as 512 Texture Address Units and 176 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce RTX 4090 should be a lot faster than the GeForce RTX 4080 overall. (explain)
Texel RateThe GeForce RTX 4090 will be much (more or less 71%) more effective at AF than the GeForce RTX 4080. (explain)
Pixel RateThe GeForce RTX 4090 should be quite a bit (approximately 59%) more effective at AA than the GeForce RTX 4080, and also able to handle higher screen resolutions more effectively. (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 information (counted in megabytes per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate 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 filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
