Intel Core i7-2920XM vs Intel Core i7-2820QM

Intel Core i7-2920XM

► remove 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 i7-2820QM

► 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.
