Intel Celeron B840

The Intel Celeron B840 is a dual core processor for entry level laptops. It is based on the Sandy Bridge architecture (2nd generation Core) and features an integrated graphics card (Intel HD Graphics based on the HD Graphics 2000 at 650-900MHz) and a reduced feature set (compared to the faster Core processors). E.g. Turbo Boost, AES, Hyperthreading, Virtualization VT-d, Quick Sync, Wireless Display and Clear Video HD are deactivated. Furthermore, some power saving features may be deactivated, leading to a shorter battery runtime compared to Core i3 processors.

Due to the slow clock speed, the performance is rather limited. Compared to the previous generation, the B840 should be similar fast as a 2 GHz Arrandale Pentium /  Celeron (e.g. P6100).

The integrated dual channel DDR3-1066/1333 memory controller supports up to 8GB.
