Intel Core i7-2620M vs Intel Core i7-2760QM

Intel Core i7-2620M

► remove 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 i7-2760QM

► remove Intel 2760QM

The Intel Core i7-2760QM is a fast high-end quad core processor for laptops and successor of the slower clocked Core i7-2720QM. 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 i7-2760QM is now manufactured in 32nm and offers an integrated graphics card and AES functions. Compared to the 2820QM, the 2760QM offers less level 3 cache (6 vs. 8MB) but should make this up due to the higher clock speed.

Sandy Bridge is the evolutionary successor of the Arrandale architecture. The most noteable improvements are the new 256Bit AVX instructions, the improved Turbo Boost and the integration of the graphics card into the 32nm CPU core. Furthermore, the integrated memory controller was improved and supports up to 8 GB DDR3-1333.

The i7-2760QM offers an integrated graphics card (Intel HD Graphics 3000) which proved to be clearly faster than the old Intel HD Graphics in the Arrandale CPUs and on a level with entry level dedicated graphics cards like the GeForce 310M. The HD Graphics 3000 also supports Turbo Boost and clocks between 650 MHz and 1300 MHz in the i7-2720QM (should be similar to the 2760QM). As the graphics card shares the fast last level cache, the processor is a bit slower with activated GPU.

The performance of the Core i7-2760QM is only slightly below the Core i7-2920XM (see benchmarks below). Therefore, the performance should be sufficient for modern 3D games and demanding applications. Thanks to the fast Turbo Boost 2.0 even single threaded applications run very fast.

The relative high TDP rating of the 2760QM of 45 Watt enables the usage of the quad core only in 15" laptops and up. However, compared to the previous generation of quad-cores, the TDP improved, as the integrated GPU is now included.
