Compare any two graphics cards:
GeForce RTX 4090 vs Radeon RX 7900 XTX
IntroThe GeForce RTX 4090 makes use of a 4 nm design. nVidia has set the core frequency at 2235 MHz. The GDDR6X RAM is set to run at a frequency of 1325 MHz on this particular card. It features 16384 SPUs as well as 512 Texture Address Units and 176 ROPs.Compare that to the Radeon RX 7900 XTX, which features a core clock speed of 1855 MHz and a GDDR6 memory speed of 2500 MHz. It also makes use of a 384-bit bus, and uses a 5 nm design. It is made up of 6144 SPUs, 384 TAUs, and 192 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce RTX 4090, in theory, should be just a bit faster than the Radeon RX 7900 XTX in general. (explain)
Texel RateThe GeForce RTX 4090 is a lot (more or less 61%) faster with regards to texture filtering than the Radeon RX 7900 XTX. (explain)
Pixel RateThe GeForce RTX 4090 should be a small bit (more or less 10%) better at AA than the Radeon RX 7900 XTX, and also will be able to handle higher screen 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 largest amount of data (counted in MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If 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 high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units 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 processed in one second. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's 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 is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
