Compare any two graphics cards:
GeForce GTX 1060 3GB vs Radeon R9 380 2G
IntroThe GeForce GTX 1060 3GB features core 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 TAUs and 48 ROPs.
Compare those specifications to the Radeon R9 380 2G, which makes use of a 28 nm design. AMD has set the core speed at 970 MHz. The GDDR5 RAM works at a speed of 1425 MHz on this specific card. It features 1792 SPUs as well as 112 TAUs and 32 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 1060 3GB should be 8% faster than the Radeon R9 380 2G in general, because of its higher data rate. (explain)
Texel RateThe Radeon R9 380 2G will be just a bit (approximately 0%) more effective at anisotropic filtering than the GeForce GTX 1060 3GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 1060 3GB is superior to the Radeon R9 380 2G, 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 (measured in megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be 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 higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
