Intel Core i5-3360M socket: Socket G2

What the Core i5-3360M is

Intel Core i5-3360M is the top 35 W dual core Ivy Bridge M part in this batch, released in June 2012. It runs at 2.8 GHz base with Turbo Boost 2.0 to 3.5 GHz, which is 200 MHz above the 3320M at both ends. Cache stays at 3 MB Intel Smart Cache, and Hyper-Threading keeps 4 threads from the two cores. The 22 nm process holds power to 35 W despite the higher clocks.

Graphics are Intel HD Graphics 4000 at 650 MHz to 1200 MHz, matching the 3320M ceiling but fed by faster cores. The block drives office displays, video calls and HD playback, with Quick Sync to speed conversion. Business boards add vPro, TXT and VT-d support, so the chip appeared in managed fleets as well as retail laptops.

The higher base clock helps sustained work that never triggers the top turbo bin, such as long compiles or large spreadsheet recalcs. Laptops pair it with HM77 or QM77, two SODIMMs and a single fan. The How to find your CPU socket type guide helps confirm whether a given laptop carries the socketed or the soldered form.

Socket and motherboard compatibility

The Core i5-3360M fits Socket G2 as an FCPGA988 part at 37.5 × 37.5 mm. It also ships soldered on BGA 1023 at 31.0 × 24.0 mm, with ordering codes SR0MV for the PGA tray and SR0MW for the BGA tray. Intel lists both sockets on the specification page, so the board and the lid must be matched before any order. A PGA chip never fits a BGA board.

Boards use the mobile 7 series, with HM76, HM77, QM77 and QS77 covering most socketed designs. The BIOS must list the exact 3360M string, since microcode and power tables differ even among 35 W twins. Any Socket G2 heatsink rated for 35 W covers it, because power did not rise with clocks here. The CPU cooler compatibility by socket guide notes laptop cooling stays board specific.

Memory, PCIe and cooling

Memory support is DDR3, DDR3L and DDR3-RS at 1333 or 1600 MT/s, two channels, up to 32 GB. Two matched modules deliver 25.6 GB/s, which the cores and the shared graphics block split. Single channel operation is the most common reason a 3360M laptop feels slow, and adding the second module is cheaper than any other change. ECC is not supported.

PCI Express is 3.0 with 16 lanes from the CPU, arranged by the board as 1x16, 2x8 or 1x8 plus 2x4. Those lanes feed optional discrete graphics, WLAN and storage, while the chipset adds SATA and USB. Most 3360M laptops rely on HD 4000 alone, which is enough for the internal panel plus an external display at office resolutions.

Cooling uses board specific pipes and fans for 35 W with a 105 C junction limit. The higher clocks make clean airflow more valuable than on slower twins, since turbo bins drop first when heat builds. A repaste during a fan swap often returns the full 3.5 GHz single core peak.

Upgrade paths

On Socket G2 the Core i5-3360M already sits near the top of the 35 W dual core stack, so same socket moves are short. A practical step is sideways to a quad core QM or MX part where the manual and power design allow it, for example to a QM chip with more cores but a different thermal class. Any such move needs a BIOS entry for the new model and a heatsink rated for the higher power. Memory and storage carry over.

For most owners the useful upgrades are memory, SSD and battery rather than the CPU. A move to a newer platform means a new laptop with BGA packaging and DDR4 memory. The soldered twin on BGA 1023 is not an upgrade path, and Intel Core i5-3320M remains the closest slower twin on the same socket.
