Intel Celeron B830 vs Intel Celeron 877
Intel Celeron B830► remove from comparison
The Intel Celeron B830 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 B830 should be similar fast as a 1.9 GHz Arrandale Pentium / Celeron (e.g. P6000).
The integrated dual channel DDR3-1066/1333 memory controller supports up to 8GB.
Intel Celeron 877► remove from comparison
The Intel Celeron 877 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, AES, VT-d or HyperThreading are deactivated. The Celeron 877 integrates a graphics card called Intel HD Graphics that is based on the HD Graphics 2000 and clocked at 350 to 1000 MHz.
The performance of the Celeron 877 should be faster than a similar clocked Arrandale Pentium CPU and therefore faster than the 1.4 GHz Pentium U5600.
The 17W TDP rating includes the integrated GPU and memory controller and therefore the 877 is suited for small subnotebooks.
