Nvidia's GeForce GTX 1080 Ti is certainly big in performance, but it doesn't have to be big in size. Zotac just proved as much with the introduction of its GeForce GTX 1080 Ti ArcticStorm Mini (ZT-P18010H-30P), a pint-sized card for liquid cooled builds where space is at a premium.
This is a smaller version of Zotac's GeForce GTX 1080 Ti ArcticStorm (ZT-P10810E-30P), although that card has a 16+2 power phase design that is conducive to overclocking. The factory clockspeeds are the same though—both have a 1,506MHz base clock and 1,620MHz boost clock, up from Nvidia's reference 1,480MHz base and 1,582MHz boost clocks.
