Intel Core i7-2920XM vs Intel Core i7-2620M

Intel Core i7-2920XM

► remove from comparison Intel 2920XM

The Intel Core i7-2920XM is the fastest quad-core processor for laptops in Q1-2011. Due to the Extreme Edition branding, the CPU should be easy to overclock (unlocked multiplicator). 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 i7-2920XM is now manufactured in 32nm, offers an integrated graphics card and AES functions. Compared to the slower clocked 2820QM, the 2920XM is specified with a higher TDP.

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 Core i7-2920XM 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. As the graphics card shares the fast last level cache, the processor is a bit slower with activated GPU.

Due to the high Turbo Boost and Hyperthreading, the performance of the Core i7-2920XM can reach levels of the fast desktop Core i5-2500K processor. Compared to the previous generation, the i7-2920XM is up to 42% faster than the old Core i7-940XM processor. Therefore, the performance should be sufficient for even the most demanding tasks like HD video editing or 3D games. Extensive benchmarks can be found at the end of this page and in our review of the new Sandy Bridge quad core processors.

The high TDP rating of the 2920XM enables the usage of the quad core only in large and heavy laptops (usually 15" and up). Compared to the previous generation of quad-cores, however, the TDP improved, as the integrated GPU is now included.

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.
