Intel Core i3-2370M

Sandy Bridge is the evolutionary successor of the Arrandale architecture. The most noteable improvements are the new 256 Bit AVX instructions, the improved Turbo Boost 2.0 (not enabled for the processor part of the 2370M) and the integration of the graphics card into the 32nm CPU core. 

Der i3-2370M offers an integrated graphics card (Intel HD Graphics 3000) which is clearly faster then the older Intel HD Graphics in the Arrandale CPUs. As the new GPU is included in the CPU, it is also manufactured in 32nm and shares the fast level 3 cache with the CPU cores (using a new ring bus). In the 2370M it is clocked from 650-1150MHz (with Turbo Boost). The faster Sandy Bridge CPUs are clocked up to 1300 MHz (like the i5-2520M).

Furthermore, an improved dual-channel DDR3 memory controller is included on the CPU die that is used by the CPU and GPU part. It supports up to 16GB DDR3-1333.

Due to the improved architecture, the average performance of the Core i7-2370M is higher than a similar clocked Arrandale Core i3 without Turbo Boost. In synthetic benchmarks, the performance should be a bit above the Core i3-390M (2.5 GHz) and therefore adequate for most applications.
