Intel To Support 128GB of DDR4 on Core 9th Gen Desktop Processors (anandtech.com)

Ian Cutress, writing for AnandTech: One of today's announcements threw up an interesting footnote worthy of further investigation. With its latest products, HP announced that their mainstream desktop platforms would be shipped with up to 32GB of memory, which was further expandable up to 128GB. Intel has confirmed to us, based on new memory entering the market, that there will be an adjustment to the memory support of the latest processors.

Normally mainstream processors only support 64GB, by virtue of two memory channels, two DIMMs per memory channel (2DPC), and the maximum size of a standard consumer UDIMM being 16GB of DDR4, meaning 4x16GB = 64GB. However the launch of two different technologies, both double height double capacity 32GB DDR4 modules from Zadak and G.Skill, as well as new 16Gb DDR4 chips coming from Samsung, means that technically in a consumer system with four memory slots, up to 128GB might be possible.

    Multitrack high-res audio editing. Video editing and compositing. Medium format 48-bit image editing.

    Anything needing a few gigabytes of RAM just to load a project will just get faster the more you can buffer stuff into memory.

    Epyc supports 2TB per chip. WTF is up with Intel?

      You are looking at Server CPUs... Intel supports up to 3.06 TB a CPU.

    Photoscan and other photogrammetry applications, when working with large image sets (1000+ photos) and high quality settings.

    After Effects uses RAM to store rendered frames, so increasing from 64 to 128GB means you can have twice as many frames stored in RAM preview at a time.

    Video editing with 6K and 8K footage, though usually in those situations you would want a CPU with more cores anyway (so a Core X processor, which can already support 128GB of memory without more dense modules.

    That is just what I can think of off the top of my head, and that others in this thread haven't already mentioned.

    > On the filesystem-level, ZFS — the revolutionary filesystem — can offer much better speed with more RAM. The abundance of RAM is also making its advanced features (like deduplication) practical.

    At scale, ZFS deduplication is a non-starter. The requirements of 5GB/TB are just not workable. I'm in the early investigative stages of a petabyte scale project and will be testing Red Hat's VDO layered on top of ZFS. The deduplication requirements of VDO are 268MB/TB, which means our 480TB storage nodes will be able to have deduplication with approximately 128GB of RAM reserved for deduplication, rather than the 2TB+ that would be required by the ZFS DDT.

    On the downside, VDO maxes at 256TB/volume, so we'll be running two volumes per Gluster node.
