Compare any two graphics cards:
GeForce GTX 1070 Ti vs Radeon RX 580
IntroThe GeForce GTX 1070 Ti makes use of a 16 nm design. nVidia has set the core frequency at 1607 MHz. The GDDR5 memory is set to run at a speed of 2000 MHz on this particular card. It features 2432 SPUs as well as 152 Texture Address Units and 64 Rasterization Operator Units.
Compare those specifications to the Radeon RX 580, which features a core clock frequency of 1257 MHz and a GDDR5 memory frequency of 2000 MHz. It also uses a 256-bit memory bus, and makes use of a 14 nm design. It features 2304 SPUs, 144 Texture Address Units, and 32 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Both cards have exactly the same memory bandwidth, so theoretically they should have the same performance. (explain)
Texel RateThe GeForce GTX 1070 Ti will be much (more or less 35%) faster with regards to AF than the Radeon RX 580. (explain)
Pixel RateThe GeForce GTX 1070 Ti is a lot (more or less 156%) more effective at anti-aliasing than the Radeon RX 580, and able to handle higher resolutions while still performing well. (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: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the 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 4 instead. The better the card's memory bandwidth, the faster 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 are applied in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
