Cores
Cores	6 Performance-cores and 4 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 2.5 GHz, max turbo 4.7 GHz; E-core base 1.8 GHz, max turbo 3.5 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.

Memory support
Memory support	Up to DDR5 4800 MT/s or up to DDR4 3200 MT/s; 2 channels, up to 192 GB	Two channels of DDR3-1066/1333. Optional maximum memory capacity and bandwidth are omitted because the retired exact-model specification page could not be read.
PCIe
PCIe	PCIe 5.0 and 4.0; 20 lanes (Up to 1x16+4, 2x8+4); DMI 4.0 x8	16 processor PCIe 2.0 lanes, configurable as one ×16 or two ×8 graphics links. A separate DMI link connects the processor to the chipset.
Process
Process	Intel 7	45 nm; Lynnfield, based on the Nehalem architecture.
Cooler
Cooler	max operating temperature 100 °C; thermal specification PCG 2020C	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.
