What the Celeron B730 is
Intel Celeron B730 is a single core Sandy Bridge mobile processor that Intel released in July 2012 for low cost socketed laptops. It runs at a fixed 1.8 GHz with no turbo, and Hyper-Threading turns the single core into 2 threads. Cache is 1.5 MB Intel Smart Cache. Power is rated at 35 W on a 32 nm process. Notebookcheck and Chipswiki confirm Hyper-Threading, while the TechPowerUp entry omits it.
Graphics are Intel HD Graphics for Sandy Bridge at 650 MHz to 1000 MHz. The block covers the laptop display and video without a card. The controller takes DDR3 SODIMMs at 1066 or 1333 MT/s.
The 100 MHz step over the B720 plus a second thread helps multitasking on single core bodies. Laptops pair it with HM76 or HM77 class boards and small drives. The How to find your CPU socket type guide shows how to confirm the socket.
Socket and motherboard compatibility
The Celeron B730 fits Socket G2 with 988 contacts in FCPGA988 form. Mobile 7 series HM76 and HM77 boards accept Sandy parts directly, while 6 series HM65 and HM67 boards carry early Sandy designs. The BIOS must list the exact B730 string.
At 35 W any Socket G2 heatsink of that class covers the chip. The Socket vs chipset: what decides whether a CPU works guide explains the chipset order for Sandy and Ivy boards.
Memory, PCIe and cooling
Memory support is DDR3-1066 and 1333, two channels, up to 16 GB. Two SODIMMs give the rated link for shared graphics. ECC is not supported.
PCI Express is 16 lanes from the CPU at PCIe 2.0 for Wi-Fi, storage and any discrete option. Most B730 bodies stay on integrated graphics.
Cooling is a 35 W single fan design. Cleaning restores the fixed 1.8 GHz behavior where dust had raised fan speed.
Upgrade paths
On Socket G2 the Celeron B730 can step to dual Celeron, Pentium and Core parts where access and BIOS allow it. Memory and storage carry over. A dual reference on the same socket is Intel Celeron 1020M.
A platform move means a new laptop. Keep the old body for basic duty after a drive wipe.
Frequently asked questions
What socket does the Intel Celeron B730 use?
It uses Socket G2 in FCPGA988 form.
Does the Celeron B730 have Hyper-Threading?
Yes. One core gives 2 threads at 1.8 GHz per Notebookcheck and Chipswiki.
