Cores
Cores	Four cores and four threads; Hyper-Threading is absent. TechRadar's exact Core i5-750 overclocking guide confirms the CPU multiplier is locked; base-clock overclocking remains possible.	Four cores and eight threads with Hyper-Threading. Alphr’s exact review explicitly lists the clock multiplier as locked.
Clocks
Clocks	Up to 3.20 GHz Turbo Boost. Intel's embedded product brief specifies 3.20 GHz with one or two active cores and 2.80 GHz with four; actual behaviour depends on workload, cooling and platform limits.	2.80 GHz base; up to 3.46 GHz with one core active, 3.33 GHz with two and 2.93 GHz with four, per Intel’s exact embedded brief. Intel’s 8 September 2009 launch states availability that day and names the 860 in its table.
