The GeForce GTX 1080 is the top-shelf GPU from NVIDIA’s Pascal generation (except for the Titan X Pascal, of course) built upon 16nm TSMC process, which is a huge leap over the last generation (Maxwell), which featured a 28nm node. Anyway, the new architecture allows better thermals, efficiency and considerably higher clock speeds than its direct predecessor the GTX 980. Also, for the first time, NVIDIA has made the difference between the desktop and the mobile variants of the Pascal GPUs mostly unnoticeable in real-life use, although there’s a slight difference according to synthetic benchmarks.
CUDA cores (2560), ROPs (64) and TMUs (213) are identical to the desktop variant of the GTX 1080 since they are based on the same GP108 chip including the memory controller, which is the highlight of the new graphics card because it features a next generation of GDDR5X memory developed by Micron allowing higher memory bandwidth on a 256-bit interface clocked at 10 000 MHz. However, there’s a small difference in the base clock speeds – 1566 – 1733 MHz for the laptop version and 1607 – 1733 MHz for the desktop variant. Both frequencies can be altered depending on the manufacturer and the cooling system’s performance.
The GPU’s power consumption is rumored to be around 165W making it suitable only for large 17 or 15-inch machines with high-performance cooling system. In addition, the graphics card delivers new and exciting features like DisplayPort 1.4, HDMI 2.0b, HDR, Simultaneous Multi-Projection, refined H.265 video encoding, etc.
