Intel Core i5-2435M vs Intel Core i5-2557M

Intel Core i5-2435M

► remove from comparison Intel 2435M

The Intel Core i5-2435M is a fast dual core processor at the time of introduction in Q3 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 2.4 GHz but due to Turbo Boost it can reach 2.7 GHz (2 cores active) and 3 GHz (1 core active). Compared to the 2510M, the 2435M does not support AES, VT-d, and Trusted Execution functions.

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 i5-2435M 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 from  650-1300MHz (with Turbo Boost). In comparison the quite similar i5-2430M offers only 1200MHz.

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 i5-2435M is higher than a similar clocked Arrandale Core i5. In our benchmarks, the 2435M was able to beat the fast Intel Core i5-560M with 2.7-3.2GHz and is therefore suited for even demanding tasks.

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

Intel Core i5-2557M

► remove from comparison

The Intel Core i5-2557M is power efficient ULV (Ultra Low Voltage) processor for thin and light laptops. The base frequency of 1.7 GHz is relatively low, but due to Turbo Boost 2.0, the CPU may clock up to 2.7 GHz (on core loaded, 2.4 GHz with both cores loaded). However, this is depending on the cooling and power consumption of the laptop. Due to HyperThreading, the i5-2557M is able to handle 4 threads in parallel. Compared to the Core i7-2657M, the i5 offers less cache but a higher base clock speed and faster graphics turbo boost.

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 1200MHz (Turbo Boost). Due to the slower clock rate, compared to HD Graphics 3000 in 35W and 45W processors (usually clocked at 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. In our benchmarks (see below), the similar 2657M ULV processor was as fast as a Core i3-2310M due to the high Turbo Boost frequencies. However, the laptop cooling system has to keep the processor relatively cool for the Turbo Boost to work often.

The TDP of 17W (includes the integrated GPU and memory controller) allows the use of the 2557M CPU in small subnotebooks.
