Samsung Announces LPDDR5X DRAM for Smartphones; 1.3x Faster Than LPDDR5 With Speeds up to 8.5Gbps

Samsung today officially announced LPDDR5X DRAM chips for smartphones and other applications. Compared to the LPDDR5 standard, the new chips bring increased speeds, and it will be no surprise that we will see them in action in several 2022 flagship handsets.

[...] In contrast to LPDDR5's 6.4Gbps maximum bandwidth, LPDDR5X can achieve 1.3-times the performance with processing speeds that go up to 8.5Gbps. Samsung has used its 14nm technology to mass produce the next-generation DRAM chips, and it will be advantageous for portable devices too because the new standard is 20 percent more energy-efficient than LPDDR5.

The press release says that 16Gb LPDDR5X chips will enable 64 GB memory packages, "accommodating increasing demand for higher-capacity mobile DRAM worldwide." In other words, Samsung is planning to put 32 dies in a single package, and eventually stick 64 gigabytes of memory in smartphones (or tablets, or laptops). Recently, Samsung has been making 16 GB packages with only 12 or 8 dies:

The 16Gb LPDDR5 can build a 16GB package with only eight chips, whereas its 1y-based predecessor requires 12 chips (eight 12Gb chips and four 8Gb chips) to provide the same capacity.

    My laptop has 64 GB, tower has 128 GB, and phone has 12 GB. It's not a long way off.

    Steam Hardware Survey [steampowered.com] says 23% of users have 8 GB of RAM, 46% have 16 GB of RAM, 13% have more than 16 GB. That's consistent with what you find in cheaper laptops and desktops (Chromebooks tend to have as little as 4 GB).

    I'm not sure I've noticed any memory packages with even 16 dies, so 32 dies for 64 GB is incredibly aggressive. Not that manufacturers won't take it. How about a laptop with 128 GB of soldered memory?
