During a presentation at the USB Global Technology Conference, Intel indicated that the roadmap for Intel Optane DIMMs lands their proprietary memory somewhere in the second half of 2018. Thus far, we’ve seen the storage and caching side of Intel Optane 3D XPoint. It seems in 2018, we’ll be afforded the opportunity to witness 3D XPoint as main memory.
We recently covered Intel’s DC P4800X data center drive, with takes on the technology from two editors in video and article form. Those content pieces served as a technology overview for 3D Xpoint and Intel Optane (and should be referenced as primer material), but both indicated a distinct lack of any consumer-focused launch for the new half-memory, half-storage amalgam.
Today, we’re back to discuss Intel’s Optane Memory modules, which will ship April 24 in the form of M.2 sticks.
As Intel’s platform for 3D Xpoint (Micron also has one: QuantX), Optane will be deployed on standardized interfaces like PCI-e AICs, M.2, and eventually DIMM form factors. This means no special “Optane port,” so to speak, and should make adoption at least somewhat more likely. There’s still a challenging road ahead for Intel, of course, as Optane has big goals to somewhat unify memory and storage by creating a device with storage-like capacities and memory-like latencies. For more of a technology overview, check out Patrick Stone’s article on the DC P4800X.
Intel’s latest memory technology has big aspirations. It has the ability to one day unify the DRAM and non-volatile memory structure, but we’re not there yet. Today, we get the Data Center Optane SSD (the DC P4800X) as a responsive, high-endurance drive specifically targeted at big data users. This is not a consumer product, but the architecture will not change in any significant ways as Optane & 3D Xpoint move to consumer devices. This information is applicable across the user space.
Upon initial release, the DC P4800X drive will be a 375GB PCIe 3.0 x4 NVMe HHHL device costing $1520 without Intel’s software, and $1951 with the Intel Memory Drive Technology software package. Later in the lifecycle, we should see 750GB and 1.5TB versions. The Optane SSD is one of three Optane technologies that Intel is marketing: Optane DIMM (fits into a DDR4 slot), Optane SSD (fits into a PCIe 3.0 x4 slot or U.2 connector), and Optane Memory (fits into an M.2 slot).
Optane is Intel’s latest memory technology. The long-term goal for Optane is for it to be used as a supplemental system memory, caching storage, and primary storage inside PCs. Intel claims that Optane is faster than Flash NAND, only slightly slower than DRAM, has higher endurance than NAND, and, due to its density, will be about half the cost of DRAM. The catch with all of these claims is that Intel has yet to release any concrete data on the product.
What we do know is that Lenovo announced that they will be using a 16GB M.2 Optane drive for caching in a couple of their new laptops during Q1 2017. Intel also announced that another 32GB caching drive should be available later in the year, something we’ve been looking into following CES 2017. This article will look into what Intel Optane actually is, how we think it works, and whether it's actually a viable device for the enthusiast market.
