Intel introduced a pair of new dual-core ultra-low voltage processors, the Core i5-3439Y and Core i7-3689Y, based on the current 22 nm "Ivy Bridge" architecture. The two feature a stunning 13W TDP, and are designed for cool Ultrabooks, with minimal cooling. The Core i5-3439Y features a nominal clock speed of 1.50 GHz, with 2.30 GHz maximum Turbo Boost, HyperThreading enabling four logical CPUs, 3 MB of L3 cache, and an SDP (scenario driven power) of just 7W. It is priced at US $250. The Core i7-3689Y, on the other side, features the same 1.50 GHz nominal clock speed, but a higher maximum Turbo Boost frequency of 2.60 GHz, and 4 MB of L3 cache. Other features are identical between the two. The i7-3689Y is priced at $362.
