Thanks to a new leaked lineup that VR-Zone has gotten their hands on, we should expect no less than 14 different Haswell CPUs from Intel next year. Intel's next-generation of CPUs will be yet another socket, meaning that your existing motherboards will have to be departed if you wish to upgrade. This new socket will be Socket 1150.
The new motherboards will need to sport a Lynx Point chipset in order to support the new Haswell-based offerings. Intel are set to launch six new standard CPUs and eight low-power CPUs. The best of the best will be the Core i7-4770K which will sport four cores with hyper-threading, all churning away at 3.5GHz. Turbo Boost will be on offer to boost the cores up to 3.9GHz, with 8MB of cache backing it up. Intel HD 4600 graphics will be included, with a 1250MHz clock speed.
There will only be one other K series chip in the new Intel Haswell Socket 1150 lineup will be the Core i5 variant, the Core i5-4670K. This chip will be a quad-core chip, sans Hyper-Threading. It will be clocked at 3.4GHz with Turbo Boost up to 3.8GHz. The Core i5-4670K will also have Intel HD 4600 graphics, but have a very slight reduction in speed to 1200MHz.
The low-power variants will have their leader, the Core i7-4770S, which will be clocked at 3.1GHz with four cores, as well as four more through Hyper-Threading. Turbo Boost will see this chip clock up to 3.9GHz and include the same Intel HD 4600 graphics at 1200Mhz. There are a bunch of other chips, all varying in clock speeds and core counts that will be included with the launch, expected sometime in 1H 2013.
Intel's Haswell CPUs continue on their 22nm process, but includes a new micro architecture that should provide some performance improvements.
