Intel Core 2 Duo P7450 vs Intel Core i7-2960XM
Intel Core 2 Duo P7450
► remove from comparisonThe Intel Core 2 Duo P7450 is a dual core processor for laptops. It features 2.1 GHz and a shared level 2 cache of 3 MB. It is based on the 45nm Penryn core, but Trusted Execution and Virtualization (VT-x) are disabled.
The P7450 uses a Penryn (Montevina Update) core that features 2 integer units, 1 floating point unit, 1 load unit, and 1 store unit in a 14-stages long pipeline. Due to the Wide Dynamic Execution Technology, the core is able to simultaneously execute up to four instructions.
The integrated Enhanced Speedstep is able to downclock the core dynamically as low as 800 MHz to save power (in idle mode).
Intel Core i7-2960XM

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.
