^ 'Intel to unify product naming scheme'.^ 'Intel Unveils World's Best Processor'.^ 'Intel Clovertowns step up, reduce power'.^ a b 'Product Change Notification #110665-00' (PDF).The Core 2 processor line was removed from the official price lists in July 2011, and the last processors were discontinued in June 2012. The last processor of the family to be released was the Core 2 Quad Q9500 in January 2010. ' Core i7' was officially launched on Novemas a family of three quad-core processor desktop models, further models started appearing throughout 2009. The successors to the Core 2 brand are a set of Nehalem microarchitecture based processors called Core i3, i5, and i7. C2QX stands for the Extreme-Editions of the Quad (QX6700, QX6800, QX6850).

With the release of the Core 2 processor, the abbreviation C2 has come into common use, with its variants C2D (the present Core 2 Duo), and C2Q, C2E to refer to the Core 2 Quad and Core 2 Extreme processors respectively. With a maximum thermal design power (TDP) of 65 W, the Core 2 Duo Conroe dissipates half the power of the less capable contemporary Pentium D-branded desktop chips that have a max TDP of 130В W. Their Core microarchitecture introduced SSSE3, Trusted Execution Technology, Enhanced SpeedStep, and Active Management Technology (iAMT2). The Core 2-branded processors feature Virtualization Technology without EPT (with some exceptions), Execute Disable Bit, and SSE3. The Core 2-branded CPUs include: Conroe/ Allendale (dual-core for desktops), Merom (dual-core for laptops), Merom-L (single-core for laptops), Kentsfield (quad-core for desktops), and the updated variants named 'Wolfdale' (dual-core for desktops), Penryn (dual-core for laptops), and 'Yorkfield' (quad-core for desktops). From December 2006, all Core 2 Duo processors were manufactured from 300 millimeter plates at Fab 12 factory in Arizona and at Fab 24-2 in County Kildare, Ireland.ДЇor a detailed discussion of CPU cores, see Intel Core (microarchitecture) В§В Processor cores. ДЄlthough Woodcrest processors are also based on the Core architecture, they are available under the Xeon brand. Intel Core 2 processors with vPro technology (designed for businesses) include the dual-core and quad-core branches. The Core 2 processor line was introduced on July 27, 2006, comprising the Duo ( dual-core) and Extreme (dual- or quad-core CPUs for enthusiasts), and in 2007, the Quad ( quad-core) and Solo ( single-core) sub-brands. The introduction of Core 2 relegated the Pentium brand to the mid-range market, and reunified laptop and desktop CPU lines for marketing purposes under the same product name, which were formerly divided into the Pentium 4, Pentium D, and Pentium M brands. The Core 2 range was the last flagship range of Intel desktop processors to use a front-side bus. The single- and dual-core models are single- die, whereas the quad-core models comprise two dies, each containing two cores, packaged in a multi-chip module. Intel Core 2 is the processor family encompassing a range of Intel's consumer 64-bit x86-64 single-, dual-, and quad-core microprocessors based on the Core microarchitecture. Allendale, Conroe, Conroe-L, Merom-2M, Merom, Merom-L, Kentsfield, Wolfdale, Yorkfield, Penryn.A result not too surprising but definitely impressive. Here's the Xbench Results Graph courtesy of Electronista:ДЄs you can see, Core i5 - a quadcore CPU, in Mac's case - is around three times better than Core 2 Duo in Hyperthreading or in deliverin thread-level parallelism on each processor resulting in more efficient use of processor resources.

If you're one of those who are still wondering if Intel Core i5 is any better than Intel Core 2 Duo CPU and is worth the upgrade, this post is for you.Д®lectronista's iMac CPU Benchmarks Test Results show that Intel's new Core i5 CPU smokes the aging Core 2 Duo processor in all relevant categories.Д¬omparing 2.66 GHz Core i5 CPU and 2.4 GHz Core 2 Duo CPU, Xbench - a CPU testing tool specifically made for the Mac OS - results show that, as expected, Core i5 is better than Core 2 Duo in terms of raw CPU power, hyperthreading, memory allocation and streaming, rendering quartz graphics (or basic graphics) like lines, squares, text and OpenGL graphics (more complex graphics) like spinning squares or 3D objects.
