Compare any two graphics cards:
Radeon RX 5700 XT vs Radeon RX 6900 XT
IntroThe Radeon RX 5700 XT comes with a GPU core speed of 1605 MHz, and the 8096 MB of GDDR6 RAM is set to run at 1750 MHz through a 256-bit bus. It also features 2560 Stream Processors, 160 TAUs, and 64 Raster Operation Units.
Compare all that to the Radeon RX 6900 XT, which makes use of a 7 nm design. AMD has clocked the core speed at 1825 MHz. The GDDR6 RAM is set to run at a frequency of 2000 MHz on this particular card. It features 5120 SPUs as well as 320 TAUs and 128 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon RX 6900 XT should in theory be a little bit better than the Radeon RX 5700 XT in general. (explain)
Texel RateThe Radeon RX 6900 XT should be a lot (more or less 127%) more effective at AF than the Radeon RX 5700 XT. (explain)
Pixel RateThe Radeon RX 6900 XT should be quite a bit (more or less 127%) more effective at FSAA than the Radeon RX 5700 XT, and should be capable of handling higher screen resolutions without slowing down too much. (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 max amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses 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 texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
