Cores
Cores	Four cores without Hyper-Threading; Intel Turbo Boost 2.0 supported. Intel VT-x supported; VT-d is not supported on this model.	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	Maximum turbo is a single-core frequency; sustained clocks and overclocking depend on motherboard support and cooling. Intel publishes TDP without a separate maximum turbo-power figure.	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.

Built-in graphics	Yes	No
Graphics
Graphics	Intel HD Graphics 4000; 650 MHz base, up to 1.15 GHz; three displays; Quick Sync Video. Intel's launch information identifies DirectX 11 support; available outputs depend on the motherboard.	No processor graphics; Intel's desktop comparison chart lists graphics as not applicable. A separate graphics solution is required.

Memory support
Memory support	Up to 32 GB; two channels; DDR3-1333/1600; 25.6 GB/s maximum bandwidth; ECC not supported.	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 3.0; configurations up to 1×16, 2×8 or 1×8+2×4, as listed by Intel. Motherboard support determines available slot configurations.	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	22 nm; Ivy Bridge; 3D tri-gate transistors; 37.5 × 37.5 mm package; 67.4°C Tcase limit, not a junction-temperature limit.	45 nm; Lynnfield, based on the Nehalem architecture.
Cooler
Cooler	LGA1155-compatible cooling required. Intel announced the quad-core family on 23 April 2012; Ars Technica's contemporaneous launch report quotes Newegg confirming retail sale on 29 April. The archived maker sale notice could not be read, so the day is supported by named secondary retail coverage.	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.
