Intel Core i5-2467M vs Intel Core i5-2540M
Intel Core i5-2467M► remove
The Intel Core i5-2467M is power efficient ULV (Ultra Low Voltage) processor for thin and light laptops. The base frequency of 1.6 GHz is relatively low, but due to Turbo Boost 2.0, the CPU may clock up to 2.3 GHz (one core loaded, 2GHz with both cores loaded). However, this is depending on the cooling and power consumption of the laptop. Due to HyperThreading, the i5-2467M is able to handle 4 threads in parallel. Compared to the slightly slower i5-2537M, the 2467 offers a faster base speed (1.6 vs 1.4GHz).
Sandy Bridge is the evolutionary successor of the Arrandale architecture. The most noteable improvements is the improved Turbo 2.0 and the integration of the graphics card into the 32nm CPU core. The 2467M offers not all features of the Sandy Bridge core, e.g. VPro, VT-d or Trusted Execution are not enabled.
The integrated Intel HD Graphics 3000 clocked at 350 or 1150MHz (Turbo Boost). Due to the slower clock rate, compared to other HD Graphics 3000 (usually 650-1100/1300MHz in non LV processors), the performance should be noticeable lower.
The TDP of 17W (includes the integrated GPU and memory controller) allows the use of the 2467M CPU in small subnotebooks.

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.
