Compare any two graphics cards:
GeForce GTX 1070 Ti vs GeForce RTX 2080
IntroThe GeForce GTX 1070 Ti makes use of a 16 nm design. nVidia has set the core frequency at 1607 MHz. The GDDR5 memory works at a frequency of 2000 MHz on this card. It features 2432 SPUs along with 152 TAUs and 64 Rasterization Operator Units.
Compare that to the GeForce RTX 2080, which features a core clock frequency of 1515 MHz and a GDDR6 memory frequency of 14 MHz. It also features a 256-bit memory bus, and makes use of a 12 nm design. It is made up of 2944 SPUs, 184 TAUs, and 64 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce RTX 2080 should be 75% faster than the GeForce GTX 1070 Ti in general, because of its greater data rate. (explain)
Texel RateThe GeForce RTX 2080 will be a bit (more or less 14%) more effective at AF than the GeForce GTX 1070 Ti. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 1070 Ti is superior to the GeForce RTX 2080, but not by far. (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 megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once 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 AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
