Cores
Cores	6 Performance-cores and 8 Efficient-cores, with Hyper-Threading; codename Raptor Lake	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.
Clocks
Clocks	P-core base 3.5 GHz, max turbo 5.3 GHz; E-core base 2.6 GHz, max turbo 4 GHz	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.

Process
Process	Intel 7	45 nm; Lynnfield, based on the Nehalem architecture.
Cooler
Cooler	max operating temperature 100 °C; thermal specification PCG 2020A	LGA1156 platform, distinct from LGA775 and LGA1366. Intel's 8 September 2009 notice names the 750 and says the new processors and P55 chipset are available that day. Cooler inclusion and package temperature are omitted where maker evidence is unavailable.
