Overview
Released
Released	January 2010	September 2009
Cores and clocks
Cores
Cores	2	4 (better)
Threads
Threads	4	4
Base clock
Base clock	2.93 GHz	2.66 GHz
Boost clock
Boost clock	–	3.2 GHz
L3 cache
L3 cache	4 MB	8 MB (better)
Cores
Cores	Two cores and four threads with Hyper-Threading. Multiplier unlock status is omitted because the bounded exact source pass did not establish it.	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	2.93 GHz base; no Turbo Boost, explicitly listed as not applicable in Intel’s 7 January 2010 launch table. The same release states that the new family is immediately available and names this model.	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.
Cache
Cache	4 MB shared L3 cache.	–
Graphics and AI
Built-in graphics
Built-in graphics	Yes	No
Graphics
Graphics	Intel HD Graphics at 733 MHz in Intel’s exact-model original launch table, also corroborated by bit-tech and the exact retail listing. The later Intel Core i3 comparison chart prints 773 MHz, conflicting with those sources.	No processor graphics; Intel's desktop comparison chart lists graphics as not applicable. A separate graphics solution is required.

Memory support
Memory support	Two channels of DDR3-1066/1333 in Intel’s exact-model comparison chart.	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	16 PCIe 2.0 lanes, as described in bit-tech’s exact review.	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.
Chipsets
Chipsets	H55, H57 or Q57 provides display outputs for integrated graphics; compatible P55 boards can use a discrete graphics card, subject to BIOS support (bit-tech).	–
Process
Process	32 nm CPU and separate 45 nm graphics die, as described by bit-tech’s exact review.	45 nm; Lynnfield, based on the Nehalem architecture.
Cooler
Cooler	Retail boxed heatsink and fan confirmed by the exact Newegg listing and Phoronix’s exact-model retail sample inspection.	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.
