Intel Celeron 847 vs Intel Celeron B815

The Intel Celeron 847 is an Ultra Low Voltage (ULV) dual core processor for entry-level laptops. It is based on the Sandy Bridge architecture but many of the features like Turbo Boost are deactivated. The Celeron 847 integrates a graphics card called Intel HD Graphics that is based on the HD Graphics 2000.

The performance of the Pentium 847 should be faster than a similar clocked Arrandale Pentium CPU and therefore on a level of the 1.2 GHz Pentium U5400.

The Intel Celeron B815 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 called Intel HD Graphics (based on the HD Graphics 2000) at 650-1050MHz 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.

Compared to the similar Celeron B810, the B815 offers a faster clocked graphics card.

Due to the slow clock speed, the performance is rather limited. Compared to the previous generation, the B810 should be similar fast as a 1.7-2 GHz Arrandale Celeron (e.g. Celeron P4500).

The integrated dual channel DDR3-1066/1333 memory controller supports up to 16GB.
