Compare any two graphics cards:
Radeon RX 5700 vs Radeon RX 6800 XT
IntroThe Radeon RX 5700 features clock speeds of 1465 MHz on the GPU, and 1750 MHz on the 8096 MB of GDDR6 RAM. It features 2304 SPUs as well as 144 TAUs and 64 ROPs.
Compare those specifications to the Radeon RX 6800 XT, which features a core clock frequency of 1825 MHz and a GDDR6 memory frequency of 2000 MHz. It also uses a 256-bit bus, and makes use of a 7 nm design. It features 4608 SPUs, 288 TAUs, and 128 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon RX 6800 XT should theoretically perform a little bit faster than the Radeon RX 5700 in general. (explain)
Texel RateThe Radeon RX 6800 XT is a lot (about 149%) better at AF than the Radeon RX 5700. (explain)
Pixel RateThe Radeon RX 6800 XT is a lot (more or less 149%) faster with regards to AA than the Radeon RX 5700, and also capable of handling higher 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 maximum amount of data (counted in MB per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
