What the Pentium B940 is

Intel Pentium B940 is a dual core Sandy Bridge mobile processor that Intel released in June 2011 for socketed budget laptops. It runs at a fixed 2.0 GHz with no turbo and no Hyper-Threading, so 2 cores give 2 threads. Cache is 2 MB Intel Smart Cache. Power is 35 W on a 32 nm process.

Pentium B parts sit above Celeron B in clocks while keeping the same 35 W envelope. Office suites and browsing feel direct at 2.0 GHz. The chip lacks threads for heavy multitasking.

Graphics are Intel HD Graphics for Sandy Bridge at 650 MHz to 1100 MHz. The block drives laptop panels and external monitors. Memory is DDR3 at 1066 or 1333 MT/s in two channels.

Socket and motherboard compatibility

The Pentium B940 fits Socket G2 with 988 contacts in FCPGA988 form. HM65 and HM67 boards carry early Sandy designs, while HM76 and HM77 accept Sandy parts directly. The BIOS must list the exact B940 string.

Board makers publish the final CPU lists. A board that omits the string may refuse to boot even when the chipset matches. The Socket vs chipset: what decides whether a CPU works guide explains why the list outranks the chipset name.

Memory, PCIe and cooling

Memory support is DDR3-1066 and 1333, two channels, up to 16 GB. Matched SODIMMs help shared graphics. ECC is not supported.

PCI Express is 16 lanes from the CPU at PCIe 2.0 for wireless and storage. Most B940 laptops stay on integrated graphics.

Cooling is a 35 W laptop fan assembly sized per chassis. Cleaning restores sustained clocks.

Upgrade paths

On Socket G2 the B940 can move to the B950 or B960 for higher clocks, or to a Core i3 M with Hyper-Threading where access and BIOS allow it. Storage and memory carry over. A nearby Pentium reference is Intel Pentium B960.

A platform move means a new laptop. Keep the old body for basic tasks after wiping the drive.

Frequently asked questions

What socket does the Intel Pentium B940 use?

It uses Socket G2 in FCPGA988 form.

Does the Pentium B940 have Hyper-Threading?

No. Two cores give 2 threads at a fixed 2.0 GHz.
