Compare any two graphics cards:
GeForce GTX 1060 3GB vs GeForce GTX 580 3GB
IntroThe GeForce GTX 1060 3GB has a core clock frequency of 1506 MHz and a GDDR5 memory speed of 2000 MHz. It also uses a 192-bit bus, and makes use of a 16 nm design. It is comprised of 1152 SPUs, 72 TAUs, and 48 Raster Operation Units.
Compare all that to the GeForce GTX 580 3GB, which features core clock speeds of 772 MHz on the GPU, and 1002 MHz on the 3072 MB of GDDR5 memory. It features 512 SPUs along with 64 Texture Address Units and 48 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 1060 3GB should theoretically be a bit superior to the GeForce GTX 580 3GB overall. (explain)
Texel RateThe GeForce GTX 1060 3GB should be much (about 119%) faster with regards to texture filtering than the GeForce GTX 580 3GB. (explain)
Pixel RateThe GeForce GTX 1060 3GB should be a lot (more or less 95%) more effective at full screen anti-aliasing than the GeForce GTX 580 3GB, and should be able to handle higher resolutions better. (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 (measured in megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. 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 better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount 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 outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
