Intel Core i5-2537M vs Intel Core i5-2450M vs Intel Core i5-2520M

Intel Core i5-2537M

► remove from comparison Intel 2537M

The Intel Core i5-2537M is power efficient ULV (Ultra Low Voltage) processor for thin and light laptops. The base frequency of 1.4 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 i5-2537M is able to handle 4 threads in parallel.

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 integrated Intel HD Graphics 3000 clocked at 350 or 900MHz (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 performance of the CPU should be a bit higher than a similar clocked Arrandale Core i5. Therefore, the performance should be similar to a Core i7-680UM / Core i3-330M.

The TDP of 17W (includes the integrated GPU and memory controller) allows the use of the 2537M CPU in small subnotebooks.

Intel Core i5-2450M

► remove from comparison Intel 2450M

The Intel Core i5-2450M is a fast dual core processor that first appeared in Dell laptops in 11/2011. 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 2.5 GHz but due to Turbo Boost it can reach 2.8 GHz (2 cores active) and 3.1 GHz (1 core active). Compared to the 2510M, the 2450M does not support VT-d and Trusted Execution functions. However, the integrated gpu offers a higher Turbo Boost clock rate.

Sandy Bridge is the evolutionary successor of the Arrandale architecture. The most noteable improvements is the improved Turbo Boost 2.0 and the integration of the graphics card into the 32nm CPU core. 

The i5-2450M 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 2435M it is clocked with  650 or 1300MHz (with 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 i5-2450M is higher than a similar clocked Arrandale Core i5. Looking at benchmarks of slower clocked Core i5 CPUs, the i5-2450M should position itself slightly above the old Core i5-620M and is therefore suited even for demanding tasks.

The 35W TDP rating includes the integrated GPU and memory controller.

Intel Core i5-2520M

► remove from comparison Intel 2520M

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.
