Intel Celeron B840

De Intel Celeron B840 is een dual-core processor voor instapmodel laptops. Hij is gebaseerd op de Sandy Bridge architectuur (2e generatie Core i) en beschikt over een geïntegreerde grafische kaart (Intel HD Graphics gebaseerd op de HD Graphics 2000 op 650-900 MHz) en gereduceerde eigenschappen (vergeleken met de snellere Core-processoren). Bijvoorbeeld Turbo Boost, AES, Hyper-Threading, Virtualization VT-d, Quick Sync, Wireless Display en Clear Video HD zijn afwezig. Verder zijn enkele energiebesparende eigenschappen gedeactiveerd, wat tot een kortere batterijlevensduur leidt vergeleken met Core i3 processoren.

Door de lagere kloksnelheid, zijn de prestaties nogal gelimiteerd. Vergeleken met de vorige generatie, zou de B840 ongeveer net zo snel moeten zijn als een 2 GHz Arrandale Pentium / Celeron (bijv. P6100).

De geïntegreerde dual-channel DDR3-1066/1333 geheugencontroller ondersteund tot 8 GB.
