What the Celeron B720 is

Intel Celeron B720 is a single core Sandy Bridge mobile processor that Intel released in January 2012 for low cost socketed laptops. It runs at a fixed 1.7 GHz with no turbo and no Hyper-Threading, so 1 core gives 1 thread. Cache is 1.5 MB Intel Smart Cache. Power is rated at 35 W on a 32 nm process.

Graphics are Intel HD Graphics for Sandy Bridge at 650 MHz to 1000 MHz. The block drives the laptop panel and an external monitor for web and office work. The on die controller takes DDR3 SODIMMs at 1066 or 1333 MT/s.

One thread suits single task classroom and web loads of the period. Laptops pair it with HM65 or HM77 class boards, a spinning drive and 2 GB of RAM. The How to find your CPU socket type guide shows how to confirm the socketed package.

Socket and motherboard compatibility

The Celeron B720 fits Socket G2 with 988 contacts in FCPGA988 form. Mobile 6 series chipsets such as HM65 and HM67 carry early Sandy boards, while 7 series HM76 and HM77 accept Sandy parts with a shipping BIOS. The board BIOS must list the exact B720 string.

At 35 W the chip fits any Socket G2 thermal design of that class. Board choice turns on screen and ports rather than power. 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 DDR3-1066 and 1333, two channels, up to 16 GB. Two SODIMMs allow service to the board maximum, though single thread loads rarely need the full link. ECC is not supported.

PCI Express is 16 lanes from the CPU at PCIe 2.0, split by the board for Wi-Fi, storage and any discrete GPU. Most B720 laptops stay on integrated graphics, since the single core cannot feed a fast card.

Cooling is board specific for 35 W with a single fan. Dust removal restores the fixed 1.7 GHz behavior more reliably than software changes.

Upgrade paths

On Socket G2 the Celeron B720 can move to dual Celeron parts, Pentium duals and Core i3 or i5 M chips where the manual allows access and the BIOS lists the target. Memory and storage carry over in most swaps. A close dual reference is Intel Celeron 1000M on the same socket.

A platform move means a new laptop on a newer BGA package. Keep the old machine for spare duty after wiping the drive.

Frequently asked questions
