However, compared to the previous generation of quad-cores, the TDP improved, as the integrated GPU is now included.

The relative high TDP rating of the 2820QM of 45 Watt enables the usage of the quad core only in 15' laptops and up. The detailed benchmark results of the 2820QM can be found in the lower section of this page. Thanks to the fast Turbo Boost 2.0 even single threaded applications run very fast. Therefore, the performance should be sufficient for modern 3D games and demanding applications. Cinebench versions) than the previous generation Core i7-940XM quad core. The performance of the Core i7-2820QM is noticeable better (e.g. As the graphics card shares the fast last level cache, the processor is a bit slower with activated GPU. The HD Graphics 3000 also supports Turbo Boost and clocks between 650 MHz and 1300 MHz. 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. Furthermore, the integrated memory controller was improved and supports up to 8 GB DDR3-1333. 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. Sandy Bridge is the evolutionary successor of the Arrandale architecture. Compared to the slower clocked 2720QM, the 2820QM offers more level 3 cache (8 vs. Compared to the previous Clarksdale quad-cores, the i7-2820QM is now manufactured in 32nm and offers an integrated graphics card and AES functions. It is based on the Sandy Bridge architecture and offers Hyperthreading to handle 8 threads at once (for a better usage of the pipeline). 2011) it was the fastest 45 Watt processor. The Intel Core i7-2820QM is a fast high-end quad core processor for laptops.
