Compare any two graphics cards:
GeForce GTX 1060 3GB vs Radeon R9 380X
IntroThe GeForce GTX 1060 3GB has clock speeds of 1506 MHz on the GPU, and 2000 MHz on the 3072 MB of GDDR5 memory. It features 1152 SPUs as well as 72 Texture Address Units and 48 ROPs.
Compare that to the Radeon R9 380X, which uses a 28 nm design. AMD has clocked the core speed at 970 MHz. The GDDR5 memory runs at a frequency of 1425 MHz on this model. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GTX 1060 3GB should be a little bit faster than the Radeon R9 380X in general. (explain)
Texel RateThe Radeon R9 380X is a small bit (approximately 15%) faster with regards to anisotropic filtering than the GeForce GTX 1060 3GB. (explain)
Pixel RateIf running with a high 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: Bandwidth is the max amount of information (in units of MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
