GPU clock rates in the 2520M core can run from 650 MHz up to 1300 MHz with Turbo Boost.įurthermore, an improved dual-channel DDR3 memory controller is included and shared between the CPU and GPU.ĭue to the new architecture and updated Turbo Boost 2.0, the average performance of the Core i7-2540M is higher than a similarly clocked Arrandale Core i5. The GPU shares the same fast 元 cache with the CPU cores by utilizing a new ring bus. The i5-2520M offers an integrated graphics card (Intel HD Graphics 3000) that is clearly faster than the older Intel HD Graphics in Arrandale CPUs. The most notable improvements are the new 256-Bit AVX instructions, updated Turbo Boost 2.0, and the integration of a GPU onto the same 32 nm die. Sandy Bridge is the evolutionary successor of the Arrandale architecture.
