Compare any two graphics cards:
GeForce GTX 780 Ti vs GeForce RTX 2060
IntroThe GeForce GTX 780 Ti features clock speeds of 875 MHz on the GPU, and 1750 MHz on the 3072 MB of GDDR5 memory. It features 2880 SPUs as well as 240 TAUs and 48 ROPs.
Compare those specifications to the GeForce RTX 2060, which features GPU core speed of 1365 MHz, and 6144 MB of GDDR6 memory set to run at 14000 MHz through a 192-bit bus. It also is made up of 1920 Stream Processors, 120 TAUs, and 48 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce RTX 2060 should in theory be just a bit superior to the GeForce GTX 780 Ti overall. (explain)
Texel RateThe GeForce GTX 780 Ti will be quite a bit (about 28%) faster with regards to AF than the GeForce RTX 2060. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce RTX 2060 is the winner, and very much so. (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 information (measured in megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling 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 record to the 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 the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
