MagyarIntel Core i5-2540M vs Intel Core i5-2520M
Intel Core i5-2540M
► remove from comparison
The Intel Core i5-2540M is a fast high end dual core processor at the time of introduction in Q1 2011. It is based on the Sandy Bridge architecture and offers Hyperthreading to handle 4 threads at once (for a better usage of the pipeline). Compared to the faster Core i7, the i5 offers a smaller last level cache of 3MB. The base clock speed is 2.6 GHz but due to Turbo Boost it can reach 3.1 GHz (2 cores active) and 3.3 GHz (1 core active).
Sandy Bridge is the evolutionary successor of the Arrandale architecture. The most noteable improvements are the new 256Bit AVX instructions, the improved Turbo 2.0 and the integration of the graphics card into the 32nm CPU core.
Der i5-2540M 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 2540M it is clocked from 650-1300MHz (Turbo Boost).
Furthermore, an improved dual-channel DDR3 memory controller is included on the CPU die that is used by the CPU and GPU part.
Due to the improved architecture and the new Turbo Boost 2.0, the average performance of the Core i5-2540M is higher than a similar clocked Arrandale Core i5. In synthetic benchmarks the performance should be on a level to the old Core i7-620M and therefore suited for even demanding tasks.
The 35W TDP rating includes the integrated GPU and memory controller.
Intel Core i5-2520M
► remove from comparison
The Intel Core i5-2520M is a fast dual-core processor released in Q1 2011. It is based on the Sandy Bridge architecture and offers Hyperthreading to run 4 threads simultaneously. Compared to the faster Core i7 family, the i5 offers smaller L3 cache at just 3MB. The base clock speed is 2.5 GHz with Turbo Boost potential up to 3 GHz for 2 active cores and 3.2 GHz for 1 active core.
Sandy Bridge is the evolutionary successor of the Arrandale architecture. 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.
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 GPU shares the same fast L3 cache with the CPU cores by utilizing a new ring bus. GPU clock rates in the 2520M core can run from 650 MHz up to 1300 MHz with Turbo Boost.
Furthermore, an improved dual-channel DDR3 memory controller is included and shared between the CPU and GPU.
Due 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. Its performance in synthetic benchmarks should be similar to the old Core i5-560M for demanding workloads.
The 35W TDP rating includes the integrated GPU and memory controller as well as the CPU itself.
