Intel Core i7-2960XM vs Intel Core i7-2820QM vs Intel Core i7-2635QM

Intel Core i7-2960XM

► remove Intel 2960XM

The Intel Core i7-2960XM is the fastest quad-core processor for laptops in Q3-2011 and successor to the Core i7-2920XM. 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 i7-2960XM is now manufactured in 32nm, offers an integrated graphics card and AES functions. Compared to the slower clocked 2860QM, the 2960XM is specified with a higher TDP.

Sandy Bridge is the evolutionary successor of the Arrandale architecture. The most noteable improvements are the new 265Bit 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 i7-2960XM 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 i7-2920XM (therefore it should be similar or faster in the 2960XM). 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, large L3 Cache, and Hyperthreading, the performance of the Core i7-2960XM is only slightly lower than the desktop Core i7-2600K. In 2011 it is the fastest mobile processors for laptops. Therefore, the performance should be sufficient for even the most demanding tasks like HD video editing or demanding 3D games.

The high TDP rating of the 2960XM enables the usage of the quad core only in large and heavy laptops (usually 15" and up). Compared to the previous generation (Clarkdale, e.g. Core i7-940XM) of quad-cores, however, the TDP improved, as the integrated GPU is now included.

Intel Core i7-2820QM

► remove Intel 2820QM

The Intel Core i7-2820QM is a fast high-end quad core processor for laptops. At the time of announcement (Jan. 2011) it was the fastest 45 Watt processor. 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 i7-2820QM is now manufactured in 32nm and offers an integrated graphics card and AES functions. Compared to the slower clocked 2720QM, the 2820QM offers more level 3 cache (8 vs. 6MB).

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 i7-2820QM 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.

The performance of the Core i7-2820QM is noticeable better (e.g. Cinebench versions) than the previous generation Core i7-940XM quad core. 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 detailed benchmark results of the 2820QM can be found in the lower section of this page.

The relative high TDP rating of the 2820QM 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.

Intel Core i7-2635QM

► remove 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.
