At present, this node, Intel, isMei GuangThe long-standing partnership between 3D XPoint and multigeneration NAND flash memory has been terminated, but the company has yet to announce any plans for mass 3D XPoint manufacturing outside the IMFT wafer factory in Utah.

Although Intel is building a "technology development line" for 3D XPoint at its factory in Rio Rancho, New Mexico. But up to now, discussions have stopped at R&D bases rather than large manufacturing centers. Earlier, it was reported that Intel might move the production line to China.

The original Optane DCPM module, also known as Apache Pass, will be succeeded by the Barlow Pass module, which coincides with the Cooper Lake (14nm) and Ice Lake (10nm) server processors launched in 2020.

In addition, the Intel roadmap extends at least two generations of unnamed DCPM modules, as well as the Sapphire Rapids processors and successors paired with them. According to Intel's previous life, Sapphire Rapids will use the DDR5 interface with the third generation Optane DCPM module.

In the near future, the current Apache Pass Optane DCPM module will soon enter the high-end workstation market with Cascade Lake.

In the long run, Intel is working withMicrosoftCooperation forThe persistent memory support in the client version lays the foundation. Unfortunately, Intel is not ready to introduce persistent memory support into its consumer hardware platform.

But in NVMeSSDIntel will launch the second generation of enterprise-class Optane SSD, in 2020, the original DC P4800X (code name Coldstream) will be replaced by Alder Stream.

Intel promises significant performance improvements, but we have some doubts about the actual performance of the toothpaste factory in recent years. From the official chart, the random I/O performance at the end of the Alder Stream curve is expected to double (see 70/30 mix).4KRandom I ≤ O).

In addition, we are not surprised to see Intel's new Optane SSD adding PCIe 4.0 support in terms of its predictable main control life. But at present, the company has not yet toAMDThe Ruilong 3000 CPU series, like the X570 chipset, popularizes PCIe 4.0 for the consumer market.

During the speech, Intel did not have much ink on the consumer-grade Aoteng product line, promoting the Optane Memory H10 hybrid (two-in-one) SSD, and the second generation of consumer Optane M.2 drives (M15 and SSD 815P product lines) were officially cut off.

Obviously, 815P's dismal exit is because the storage capacity of 118GB is too tight. As for M15, there are not enough mechanical hard drives to support the new generation of cache drives. However, the current M10 and SSD 800P have not been discontinued.

In the development of 3D NAND, Intel mainly focuses on QLC NAND. Taking SSD 660p as an example, this is the most successful consumer-grade QLC solid-state hard disk on the market. It will soon be replaced by 665p (from 64 to 96 layers of QLD NAND flash).

We don't expect 665p to bring a huge performance boost, but it's expected to meet you by the end of this year. Later, Intel will focus on developing the next generation of 144 3D NAND, and the company is still working on the design of 3D floating gate memory cells.

Intel claims that its own design offers a much better data retention capability than the charge trap flash memory used by most competitors, but it appears to be more likely to use the 72-72-layer design, not 48-48, to reach its declared 144-layer.

Finally, new SSD products based on Intel Enterprise/Data Center Flash will arrive in 2020, including 144-layer QLD solid-state hard disk, but the specific model specifications are difficult to guess.
