Compare any two graphics cards:
GeForce GTX 1060 3GB vs Radeon R9 M390X
IntroThe GeForce GTX 1060 3GB uses a 16 nm design. nVidia has clocked the core speed at 1506 MHz. The GDDR5 memory runs at a frequency of 2000 MHz on this model. It features 1152 SPUs as well as 72 Texture Address Units and 48 Rasterization Operator Units.
Compare all that to the Radeon R9 M390X, which comes with a core clock speed of 723 MHz and a GDDR5 memory speed of 1250 MHz. It also uses a 256-bit bus, and uses a 28 nm design. It is comprised of 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 1060 3GB should theoretically be quite a bit faster than the Radeon R9 M390X overall. (explain)
Texel RateThe GeForce GTX 1060 3GB will be a little bit (more or less 17%) faster with regards to AF than the Radeon R9 M390X. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 1060 3GB is a better choice, by a large margin. (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: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
