Review: Lenovo Helix Ultrabook Convertible

Performance

The tested Helix was running 64-bit Windows 8 Pro on 4-GB DDR3 RAM and an Intel Core i5-3427U 1.8 GHz processor with 3MB cache. It's also available with a Core i7-3667U 2GHz processor with 4-MB cache. Both are dual-core third-generation (Ivy Bridge) CPUs with Intel HD Graphics 4000 GPUs. Geekbench 2.3 from Primate Labs delivered a high score of 7,524, good enough for eighth place on the CRN Test Center's all-time list. The unit performs a cold boot in about 9 seconds and wakes from sleep in less than 2 seconds.
