Compare any two graphics cards:
GeForce GTX 1060 3GB vs GeForce GTX 580 3GB
IntroThe GeForce GTX 1060 3GB comes with a GPU core speed of 1506 MHz, and the 3072 MB of GDDR5 RAM is set to run at 2000 MHz through a 192-bit bus. It also features 1152 SPUs, 72 Texture Address Units, and 48 ROPs.
Compare those specs to the GeForce GTX 580 3GB, which comes with core clock speeds of 772 MHz on the GPU, and 1002 MHz on the 3072 MB of GDDR5 RAM. It features 512 SPUs along with 64 TAUs and 48 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 1060 3GB is 2% faster than the GeForce GTX 580 3GB in general, because of its greater data rate. (explain)
Texel RateThe GeForce GTX 1060 3GB will be much (approximately 119%) more effective at AF than the GeForce GTX 580 3GB. (explain)
Pixel RateThe GeForce GTX 1060 3GB should be quite a bit (approximately 95%) faster with regards to AA than the GeForce GTX 580 3GB, and will be capable of handling higher screen 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: Bandwidth is the max amount of information (measured in megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units of the card by the core 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 that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
