Intel Core i7-2637M vs Intel Core i7-2620M vs Intel Core i7-2640M

Intel Core i7-2637M

► remove from comparison

The Intel Core i7-2637M 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 2.8 GHz (on core loaded, 2.5 GHz with both cores loaded). However, this depends on the cooling and power consumption of the laptop. Due to HyperThreading, the i7-2637M is able to handle 4 threads in parallel. Compared to the slower i7-2617M, the 2637M offers a higher clock speed (processor core and turbo, graphics turbo).

Sandy Bridge is the evolutionary successor of the Arrandale architecture. The most notable 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 without the Turbo, compared to HD Graphics 3000 in 35W and 45W processors (usually clocked at 650 base speed 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. Thanks to the high Turbo Boost frequencies, the performance should be similar to the Core i3-2310M. 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 2637M CPU in small subnotebooks.

Intel Core i7-2620M

► remove from comparison Intel 2620M

The Intel Core i7-2620M is the fastest 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 slower Core i5, the i7 offers a larger last level cache of 4MB. The base clock speed is 2.7 GHz but due to Turbo Boost it can reach 3.2 GHz (2 cores active) and 3.4 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 i7-2620M 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 2620M 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 i7-2620M is higher than a similar clocked Arrandale Core i7. In synthetic benchmarks the performance ranges from the old Core i7-620M to the Core i7-820QM quad core processor. On average it should be on a level of the fast Core i7-640M.

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

Intel Core i7-2640M

► remove from comparison Intel 2640M

The Intel Core i7-2640M is the fastest dual core processor at the time of introduction in Q3 2011 and successor of the slower clocked i7-2620M. 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 slower Core i5, the i7 offers a larger last level cache of 4MB. The base clock speed is 2.8 GHz but due to Turbo Boost it can reach 3.3 GHz (2 cores active) and 3.5 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 i7-2640M 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 2620M it is clocked from 650-1300MHz (Turbo Boost), and in the 2640M it should be similar.

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 i7-2640M is higher than a similar clocked Arrandale Core i7 dual core. The performance should even excel the old high-end quad core models like the Core i7-820QM.

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