Compare any two graphics cards:
GeForce GTX 1060 3GB vs Radeon R9 380X
IntroThe GeForce GTX 1060 3GB has a clock speed of 1506 MHz and a GDDR5 memory speed of 2000 MHz. It also features a 192-bit bus, and makes use of a 16 nm design. It is comprised of 1152 SPUs, 72 Texture Address Units, and 48 ROPs.
Compare those specs to the Radeon R9 380X, which features a clock speed of 970 MHz and a GDDR5 memory speed of 1425 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It is made up 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 perform just a bit faster than the Radeon R9 380X overall. (explain)
Texel RateThe Radeon R9 380X will be a small bit (about 15%) better at texture filtering than the GeForce GTX 1060 3GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 1060 3GB is superior to the Radeon R9 380X, 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: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better 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 maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
