Compare any two graphics cards:
Radeon RX 5700 XT vs Radeon RX 6900 XT
IntroThe Radeon RX 5700 XT features a clock speed of 1605 MHz and a GDDR6 memory speed of 1750 MHz. It also features a 256-bit memory bus, and makes use of a 7 nm design. It is made up of 2560 SPUs, 160 Texture Address Units, and 64 ROPs.
Compare all that to the Radeon RX 6900 XT, which features core clock speeds of 1825 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 RAM. It features 5120 SPUs along with 320 TAUs and 128 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Radeon RX 6900 XT is 14% quicker than the Radeon RX 5700 XT in general, due to its higher data rate. (explain)
Texel RateThe Radeon RX 6900 XT should be quite a bit (approximately 127%) faster with regards to texture filtering than the Radeon RX 5700 XT. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon RX 6900 XT is the winner, 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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
