Compare any two graphics cards:
GeForce RTX 4090 vs Radeon RX 6950 XT
IntroThe GeForce RTX 4090 has a core clock frequency of 2235 MHz and a GDDR6X memory frequency of 1325 MHz. It also uses a 384-bit memory bus, and uses a 4 nm design. It is comprised of 16384 SPUs, 512 TAUs, and 176 Raster Operation Units.Compare all of that to the Radeon RX 6950 XT, which features a clock frequency of 1925 MHz and a GDDR6 memory speed of 2250 MHz. It also uses a 256-bit bus, and makes use of a 7 nm design. It is comprised of 5120 SPUs, 320 Texture Address Units, and 128 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce RTX 4090 should theoretically be much better than the Radeon RX 6950 XT overall. (explain)
Texel RateThe GeForce RTX 4090 is quite a bit (approximately 86%) faster with regards to AF than the Radeon RX 6950 XT. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce RTX 4090 is superior to the Radeon RX 6950 XT, by a large margin. (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 data (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling 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 the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines 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 output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
