Perhaps the most interesting aspect of Samsung’s booth is what they weren’t showing: laptops. They had exactly one laptop on display, the new ATIV Book 9 with Core M-5Y10c – that’s the configurable TDP “c” variant of Core M, which allows the manufacturer to target different power levels. In the case of the 5Y10c, it can target 3.5W and 6W as well as the default 4.5W, allowing for lower performance buy potentially increased battery life (or at least less heat) on the one hand, and higher performance but more heat (and potentially less battery life) on the other. The configurable TDP mostly affects the base frequency, with the default being 800MHz and TDP down dropping that to 600MHz while TDP up bumps it to 1GHz – the maximum Turbo Boost remains 2GHz in all modes, as far as I’m aware.
