  • About

    This memorable blog is about DRAM in all its forms, especially the latest standards: DDR3, DDR4, LPDDR3 and LPDDR4. Nothing is off limits--the memory market, industry trends, technical advances, system-level issues, signal integrity, emerging standards, design IP, solutions to common problems, and other stories from the always entertaining memory industry.

Intel announces DDR4 support

Posted by Marc Greenberg on March 20th, 2014

This is a big day for DDR4: For the first time, Intel has announced DDR4 support in their desktop CPU roadmap.

If you have been paying attention to other sources (or if you have private access to data as I do) then you’ve known that Intel has been working on DDR4 for a while, and DDR4 was shown at Intel Developer Forum last year.

Intel has announced:
– An 8-core desktop processor, “New Intel® Core™ i7 Processor Extreme Edition” (Codename Haswell-E) as the first desktop platform supporting DDR4 memory, with availablity in 2H2014
– A 5th generation Intel® Core™ processor with Intel® Iris™ Pro (Codename Broadwell) based on 14nm manufacturing process

I’ll be doing a blog on Iris Pro shortly…
