Leaked slides presumably from an Intel Corp.’s document reveal that the world’s largest chipmaker is preparing a rather revolutionary update to its high-end desktop (HEDT) platform next year with the introduction of code-named Haswell-E product. Not only the new high-end client chips will finally see more physical cores, but they will also gain a number of other improvements.


The next year’s enthusiast desktop platform will pack a number of firsts and will naturally bring a significant performance boost over regular desktop platforms as well as over existing and incoming HEDT solutions based on code-named Ivy Bridge-E processor. Intel Core i7 “Haswell-E” central processing units will pack six or eight x86 cores with Haswell micro-architecture and Hyper-Threading technology, 20MB of L3 cache, quad-channel DDR4 memory controller (2133MHz maximum clock-speed, up to one DIMM per channel) as well as Turbo Boost 2 technology, reports VR-Zone web-site, which published the slides from Intel’s roadmap. The processors will traditionally have 40 integrated PCI Express 3.0 lanes, but will lack built-in graphics adapter, which is logical.

The forthcoming enthusiast-class desktop platform will rely on code-named Wellsburg chipset and will use all-new LGA2011-3 socket. Interestingly, the new microprocessors will have up to 140W thermal design power, which points to high clock-rate in addition to high core-count. Besides, traditionally Intel will unlock all multipliers on HEDT platform to allow maximum level of customization.

Based on Intel’s expectations, the new eight-core Core i7 “Haswell-E” will bring 55% performance improvement over quad-core Core i7 “Haswell” processor clocked at 3.70GHz. When both frequency increases as well as increased core-count are taken into account, the Haswell-E should be over 30% faster compared to Ivy Bridge-E.

Intel did not comment on the news-story.
