Compare any two graphics cards:
GeForce RTX 3070 Ti vs Radeon RX 6900 XT
IntroThe GeForce RTX 3070 Ti comes with a GPU clock speed of 1575 MHz, and the 8192 MB of GDDR6X memory runs at 1188 MHz through a 256-bit bus. It also is made up of 6144 SPUs, 192 Texture Address Units, and 96 ROPs.
Compare all of that to the Radeon RX 6900 XT, which has 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 Texture Address Units and 128 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce RTX 3070 Ti should theoretically be a bit faster than the Radeon RX 6900 XT in general. (explain)
Texel RateThe Radeon RX 6900 XT is a lot (about 93%) more effective at AF than the GeForce RTX 3070 Ti. (explain)
Pixel RateThe Radeon RX 6900 XT will be much (approximately 54%) faster with regards to full screen anti-aliasing than the GeForce RTX 3070 Ti, and will 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 largest amount of data (counted in MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, 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 figure is worked out by multiplying the total amount of texture units by the core clock 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 in a second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
