Intel's pocket-sized prodigy, NUC (next unit of computing), made waves since 2012, when it launched as a full-fledged desktop system, based on Core "Ivy Bridge" platform. The industry has since been looking forward to second-generation NUC, which runs the company's latest Core "Haswell" processors. One such fun-size powerhouse was spotted at PAX Prime. Labelled Intel D54250WYK, the kit runs a Core i5-4250U dual-core processor (1.30 GHz clocks, 2.60 GHz Turbo Boost, 3 MB L3 cache, HD Graphics 5000, 15W TDP). The reference-design enclosure is smaller in size than its predecessor, measuring 116.6 mm x 112 mm x 34.5 mm, compared to the original's 116.5 mm x 112 mm x 39.3 mm. Connectivity on the device include a single 3.5 mm headset jack, four USB 3.0 ports, gigabit Ethernet, HDMI, and mini-DisplayPort (both of which give out 7.1-channel digital audio). Wireless connectivity options could include anything from 802.11 b/g/n (or even 802.11 ac), Bluetooth 4.0. Intel could detail, or perhaps even launch, its next-generation NUC at IDF San Francisco.
