Arrandale is a later mobile processor but opens a new line of mid-range dual-core processors with integrated graphics. At the time of its release at the Intel Developer Forum on September 23, 2009, Clarksfield processors were significantly faster than any other laptop processor, [ 2 ] including the Core 2 Extreme QX9300.
Single core turbo boost up to 5.3 GHz (300 MHz higher); all-core turbo boost up to 4.9 GHz; Thermal Velocity Boost for Core i9; [13] Turbo Boost Max 3.0 support for Core i7 and i9; DDR4-2933 memory support for Core i7 and i9; DDR4-2666 for Core i3, Core i5, Pentium Gold, Celeron; 400-series chipset based on the LGA 1200 socket
An Intel November 2008 white paper [10] discusses "Turbo Boost" technology as a new feature incorporated into Nehalem-based processors released in the same month. [11]A similar feature called Intel Dynamic Acceleration (IDA) was first available with Core 2 Duo, which was based on the Santa Rosa platform and was released on May 10, 2007.
Transactional Synchronization Extensions (TSX), also called Transactional Synchronization Extensions New Instructions (TSX-NI), is an extension to the x86 instruction set architecture (ISA) that adds hardware transactional memory support, speeding up execution of multi-threaded software through lock elision.
Further, a "cumulative clock rate" measure is sometimes assumed by taking the total cores and multiplying by the total clock rate (e.g. a dual-core 2.8 GHz processor running at a cumulative 5.6 GHz). There are many other factors to consider when comparing the performance of CPUs, like the width of the CPU's data bus , the latency of the memory ...
the Core i3-2102 (3.1 GHz, 3 MB cache) desktop processor could be upgraded to the Core i3-2153 with a higher frequency (3.6 GHz) the Pentium G622 desktop processor (2.6 GHz, 3 MB cache) could be upgraded to the Pentium G693 with a higher frequency (3.2 GHz) The Sandy Bridge upgrade program was available in U.S., Canada, Mexico, Brazil, Peru ...

Unlike the original Core, Intel Core 2 is a 64-bit processor, supporting Intel Extended Memory 64 Technology (EM64T). Another difference between the original Core Duo and the new Core 2 Duo is an increase in the amount of level 2 cache. The new Core 2 Duo has tripled the amount of on-board cache to 6 MB.
