What the Core i7-2720QM is
Intel Core i7-2720QM is a quad core Sandy Bridge mobile processor that Intel released in January 2011 for socketed performance laptops. It runs at 2.2 GHz base with turbo to 3.3 GHz on one core and includes Hyper-Threading, so 4 cores give 8 threads. Cache is 6 MB Intel Smart Cache. Power is 45 W on a 32 nm process.
Turbo to 3.3 GHz gives strong single threaded speed for creation tasks. Business workstations chose it for the mix of threads and clocks. ThinkPad T520 class machines list it with 6 MB cache and 45 W cooling.
Graphics are Intel HD Graphics 3000 at 650 MHz to 1300 MHz. The block drives laptop panels and external monitors. Many 2720QM laptops pair it with a discrete GPU over PCIe lanes.
Socket and motherboard compatibility
The Core i7-2720QM fits Socket G2 with 988 contacts in FCPGA988 form. This page covers the socketed rPGA version. The same silicon also ships soldered on BGA 1224 for thin performance bodies, which is not a field swap. HM65 and HM67 boards carry early Sandy quads, while HM76 and HM77 accept Sandy parts directly.
The board BIOS must list the exact 2720QM string. The Socket vs chipset: what decides whether a CPU works guide explains why the list outranks the chipset name.
Memory, PCIe and cooling
Memory support is DDR3-1066 to 1600, two channels, up to 32 GB. Two matched modules help the shared graphics block. ECC is not supported.
PCI Express is 16 lanes from the CPU at PCIe 2.0 for discrete graphics, wireless and storage. Performance laptops of 2011 often paired the quad with a separate GPU.
Cooling is a 45 W laptop assembly with shared pipes for CPU and GPU where fitted. Cleaning restores sustained turbo behavior.
Upgrade paths
On Socket G2 the 2720QM can move to the 2760QM or 2820QM for higher clocks, where access and BIOS allow it. Storage and memory carry over. A nearby socketed quad reference is Intel Core i7-2630QM.
A platform move means a new laptop. Keep the old body for desk duty after wiping the drive.
