Intel Core i7-2635QM vs Intel Core i7-2649M

Intel Core i7-2635QM

► remove from comparison Intel 2635QM

The Intel Core i7-2635QM is a fast quad core processor for laptops. It is based on the Sandy Bridge architecture and offers Hyperthreading to handle 8 threads at once (for a better usage of the pipeline). Compared to the previous Clarksdale quad-cores, the i7-2635QM is now manufactured in 32nm and offers an integrated graphics card and AES functions. Compared to the faster Core i7, the 2635QM does not support Trusted Execution functions and VT-d (VT-x Virtualization only).

Compared to the Core i7-2630QM, the 2635QM offers a slightly higher Turbo Boost frequency for the GPU (1200MHz versus 1100MHz) and is offered in the BGA Package (2630QM rPGA).

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 i7-2635QM 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 2635QM it is clocked from 650-1200MHz (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.

The performance of the Core i7-2635QM should be about 10-15% faster than a similar clocked Clarksfield Core i7 (see first tests by Anandtech). Therefore, the 2635QM should be on a level (or even faster) than a Core i7-920XM Quad-Core.

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.
