Intel's next-generation Core i7 "Haswell-E" HEDT (high-end desktop) processor lineup, slated for later this year, accompanied by the company's X99 Express chipset, will launch at three price-points, predictably, succeeding the current Core i7-4820K, i7-4930K, and i7-4960X. The platform will herald a new LGA socket, which will have 2,011 pins, but will not be compatible with current LGA2011 platforms based on the X79 Express chipset. That's because "Haswell-E" will be among the first client platforms to support DDR4-SDRAM memory. All Haswell-E chips will support DDR4-2133 MHz out of the box.

Moving on to the actual lineup, and it begins with the Core i7-5820K. This is a six-core chip, and a welcome departure from Intel's sub-$400 HEDT chips being quad-core. Whether it supports HyperThreading, is not known. You still get 6 physical cores to plow through work. The chip also features a staggering 15 MB of L3 cache, clock speed of 3.30 GHz with a couple of notches of Turbo Boost, and a quad-channel DDR4 integrated memory controller. Oh, and there's the unlocked BClk multiplier. Sounds too good to be true for a sub-$400 chip? Here's the catch - its on-die PCI-Express Gen 3.0 root complex will have fewer lanes. It can spare just 16 + 8 lanes for discrete graphics cards. For boards with three long x16 slots, that would mean x16/NC/x8, or x8/x8/x8, with an additional x4 link.
