What the Pentium G622 is
Intel Pentium G622 is a dual core Sandy Bridge desktop processor that Intel released in May 2011 alongside the G620. It runs at a fixed 2.6 GHz with no turbo and no Hyper-Threading, so 2 cores give 2 threads. Cache is 3 MB Intel Smart Cache. Power is 65 W on a 32 nm process.
The G622 matches the G620 on cores, clocks, cache and power. Intel grouped the two in the same discontinuance notice, which shows they shared a market window. System behavior is identical in office builds.
Graphics are Intel HD Graphics for Sandy Bridge at 850 MHz to 1100 MHz. Board outputs drive office monitors without a card. The How to find your CPU socket type guide helps confirm the LGA 1155 package from the tower model.
Socket and motherboard compatibility
The Pentium G622 fits LGA 1155 in FCLGA1155 form. H61, H67, P67, Z68, B75 and H77 boards boot Sandy parts directly. No BIOS update is needed for this chip.
Like other Sandy duals, graphics use depends on the chipset. P67 ignores the integrated block, while H and Z boards expose it. Match the board to the monitors before reusing a spare tower.
Memory, PCIe and cooling
Memory support is DDR3-1066 and 1333, two channels, up to 32 GB. A 4 GB to 8 GB pair covers office use. ECC is not supported.
PCI Express is 16 lanes from the CPU at PCIe 2.0. The x16 slot stays free for I/O cards in most G622 offices.
Cooling is the stock 65 W desktop heatsink on 75 × 75 mm spacing. The CPU cooler compatibility by socket guide notes this pattern carries across several LGA generations.
Upgrade paths
On LGA 1155 the G622 can move to the G630, G840 or G860 for higher fixed clocks on the same board. A Core i3 adds Hyper-Threading for threaded office apps. A nearby dual reference is Intel Pentium G860T at 35 W.
A platform change to DDR4 needs a new board and RAM. Keep the G622 system for spare office duty.
Frequently asked questions
