Intel Celeron 797 vs Intel Celeron B800 vs Intel Celeron 847

Intel Celeron 797

► remove from comparison

The Intel Celeron 797 is a single-core ULV processor for entry level laptops. It is based on the Sandy Bridge architecture (2nd generation Core) and features an integrated graphics card (most likely Intel HD Graphics based on the HD Graphics 2000 at 350-950MHz) 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. 

Due to the slow clock speed, the performance is rather limited. Compared to older processors, the 797 should be similar fast as a Celeron M 540 clocked at 1.86 GHz.

Intel Celeron B800

► remove from comparison

The Intel Celeron B800 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 B800 should be similar fast as a 2 GHz Core 2 Duo processor.

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

Intel Celeron 847

► remove from comparison

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 17W TDP rating includes the integrated GPU and memory controller and therefore the 847 is suited for small subnotebooks.
