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 memory runs at 2000 MHz through a 192-bit bus. It also features 1152 Stream Processors, 72 Texture Address Units, and 48 ROPs.
Compare those specs to the GeForce GTX 580 3GB, which features clock speeds of 772 MHz on the GPU, and 1002 MHz on the 3072 MB of GDDR5 memory. It features 512 SPUs as well as 64 TAUs and 48 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 1060 3GB should in theory be a small bit superior to the GeForce GTX 580 3GB overall. (explain)
Texel RateThe GeForce GTX 1060 3GB is quite a bit (about 119%) more effective at texture filtering than the GeForce GTX 580 3GB. (explain)
Pixel RateThe GeForce GTX 1060 3GB is a lot (approximately 95%) better at FSAA than the GeForce GTX 580 3GB, and also 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 largest amount of information (in units of MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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 max fill rate.
