Intel Core i7-2649M vs Intel Core i7-2657M vs Intel Core i7-2617M

Intel Core i7-2649M

► remove from comparison

The Intel Core i7-2649M is power efficient LV (Low Voltage) processor for laptops. The base frequency of 2.3 GHz is relatively low, but due to Turbo Boost 2.0, the CPU may clock up to 3.2 GHz (one core loaded, 2.9 GHz with both cores loaded). However, this is depending on the cooling and power consumption of the laptop. Due to HyperThreading, the i7-2649M is able to handle 4 threads in parallel. Compared to the similar called Core i7-2620M, the 2649M is slower but also needs less power (25W versus 35W TDP).

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 500 or 1100MHz (Turbo Boost). Due to the slower base clock rate, compared to HD Graphics 3000 in 35W and 45W processors (usually clocked at 650), the performance should be a bit lower.

The performance of the CPU should be a bit higher than a similar clocked Arrandale Core i7 LV. Therefore, the performance should a bit above the Core i3-390M if the Turbo can be used often.

The TDP of 25W (includes the integrated GPU and memory controller) allows the use of the 2649M CPU in thin notebooks.

Intel Core i7-2657M

► remove from comparison

The Intel Core i7-2657M 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 2.7 GHz (on core loaded, 2.4 GHz with both cores loaded). However, this depends on the cooling and power consumption of the laptop. Due to HyperThreading, the i7-2657M is able to handle 4 threads in parallel. Compared to the slower i7-2617M, the 2657M offers a higher clock speed (processor core and turbo, graphics turbo).

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 1000MHz (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 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 2657M CPU in small subnotebooks.

Intel Core i7-2617M

► remove from comparison Intel 2617M

The Intel Core i7-2617M is power efficient ULV (Ultra Low Voltage) processor for thin and light laptops. The base frequency of 1.5 GHz is relatively low, but due to Turbo Boost 2.0, the CPU may clock up to 2.6 GHz (on core loaded, 2.3 GHz with both cores loaded). However, this is depending on the cooling and power consumption of the laptop. Due to HyperThreading, the i7-2617M is able to handle 4 threads in parallel. Compared to the slower i5-2537M, the 2617M offers a higher clock speed (processor core and turbo, graphics turbo) and more last level cache.

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 950MHz (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. Therefore, the performance should be similar to a Core i3-350M if the Turbo can be used often.

The TDP of 17W (includes the integrated GPU and memory controller) allows the use of the 2617M CPU in small subnotebooks.
