Intel Core i7-3632QM socket: Socket G2

What the Core i7-3632QM is

Intel Core i7-3632QM is a low power quad core Ivy Bridge mobile processor that Intel announced in late 2012 for thin performance laptops. It runs at 2.2 GHz base with turbo to 3.2 GHz, with 6 MB Intel Smart Cache and Hyper-Threading for 8 threads. Power is rated at 35 W on a 22 nm process. Intel lists the launch as the third quarter of 2012, with retail availability in October, which is why dates vary by source.

Graphics are Intel HD Graphics 4000 at 650 MHz to 1150 MHz. The block covers office displays alone, while quad thin bodies often add a modest discrete GPU for heavier work. Memory is DDR3, DDR3L and DDR3-RS at 1333 or 1600 MT/s for up to 32 GB.

Eight threads at 35 W bring threaded work to slimmer bodies than 45 W quads allow. All core loads run slower than the 45 W QM group, while bursts still reach 3.2 GHz. Laptops pair it with HM77 or QM77 and dual SODIMMs. The How to find your CPU socket type guide helps confirm the socketed form.

Socket and motherboard compatibility

The Core i7-3632QM fits Socket G2 as an FCPGA988 part at 37.5 × 37.5 mm. It also ships soldered on BGA 1224 at 31.0 × 24.0 mm, and Intel keeps separate rPGA and BGA ARK entries for the two packages. Match the sSpec on the lid to the board, since the packages never interchange. The BIOS must list the exact 3632QM string with late 2012 microcode.

Boards are Socket G2 quad capable designs with mobile 7 series chipsets. At 35 W the chip fits a wider set of heatsinks than 45 W quads. The Socket vs chipset: what decides whether a CPU works guide explains why the maker list decides the result.

Memory, PCIe and cooling

Memory support is DDR3, DDR3L and DDR3-RS at 1333 or 1600 MT/s, two channels, up to 32 GB for 25.6 GB/s. Two matched modules feed eight threads and shared graphics. ECC is not supported.

PCI Express is 16 lanes from the CPU at PCIe 3.0, split as 1x16, 2x8 or 1x8 plus 2x4. Thin quad bodies use lanes for a modest discrete GPU plus SSDs and Wi-Fi. Integrated graphics handle the panel when switching saves power.

Cooling is board specific for 35 W with a 105 C junction class. Slim quad heat still needs clean fans and full pipes to hold turbo. The PGA lid allows repaste, unlike the soldered twin.

Upgrade paths

On Socket G2 the Core i7-3632QM can move to faster QM quads where cooling and BIOS allow it, including 45 W parts with a heatsink review. Memory and storage carry over in most swaps. The soldered twin on BGA 1224 is never an upgrade target. A slower 35 W quad comparison is Intel Core i7-3612QM.

A platform change means a new performance laptop on a newer BGA package. Keep the current board for threaded work where eight threads at 35 W still meet the need.
