Pentium Dual Core B970 2.3GHz is a Dual-Core Sandy Bridge based CPU for weaker (non-gaming) laptops.
It's based on the Sandy Bridge architecture but many of its features, such as Turbo Boost are disabled. It has 2 Cores, clocked at 2.3GHz and features integrated graphics called Intel HD 2000, clocked at 650MHz that can go up to 1100MHz in Turbo mode.
Its gaming performance is average and enough to play every game out there but a bottleneck for high-end GPUs.
