Samsung has announced the mass production of 16 Gb GDDR6 SDRAM chips with a higher-than-expected pin speed. The chips could see use in upcoming graphics cards that are not equipped with High Bandwidth Memory:

Samsung has beaten SK Hynix and Micron to be the first to mass produce GDDR6 memory chips. Samsung's 16Gb (2GB) chips are fabricated on a 10nm process and run at 1.35V. The new chips have a whopping 18Gb/s pin speed and will be able to reach a transfer rate of 72GB/s. Samsung's current 8Gb (1GB) GDDR5 memory chips, besides having half the density, work at 1.55V with up to 9Gb/s pin speeds. In a pre-CES 2018 press release, Samsung briefly mentioned the impending release of these chips. However, the speed on release is significantly faster than the earlier stated 16Gb/s pin speed and 64GB/s transfer rate.

18 Gbps exceeds what the JEDEC standard calls for.

    Since multiple dies are used, you actually end up with a much higher memory bandwidth than 72 GB/s, possibly up to 864 GB/s by Wccf's reckoning, which is in the ballpark of GPUs using HBM2.

    [...] HBM3 could probably enable a product with 4 TB/s memory bandwidth, a full million times faster than your old stuff.

    I'm... speechless. That just utterly and totally boggles my mind. I remember trying to squeeze out a couple more bytes from CONFIG.SYS and AUTOEXEC.BAT so I could get a program to fit into available memory under DOS 3.1 Now, systems with 16 GB of RAM are no big deal. (That mainframe I mentioned in the GP post? It had 32 MB of main memory and 256 MB of extended memory.) A Raspberry Pi has more memory than that... and it's probably much faster, too. All for the princely sum of... $35. And draws under 7(?) watts, peak load.

    I think we'll see some sort of new transistor that uses near-threshold voltages [phys.org] or exploits quantum effects [wikipedia.org]. We could get today's 200 Watt chips to shrink to below 1 Watt of power consumption for the same performance, and the massive reduction in heat will allow easy stacking, which will be expressed by massively increasing core counts (you better learn how to write multithreaded software before a bot does it for you). Meanwhile, HBM is already at 8-16 layers and NAND is around 96-128. Watch those increase to hundreds or tens of thousands of layers.

    The party isn't over yet.

    And yet, Windows still slows down, locks up, and barfs its dysenteric guts out on the regular on that 16GB home computer.

      Swap HDD for SSD, remove pre-installed bloatware, disable unnecessary services [blackviper.com], and install ad/script blockers and even the Windows computer should be fine.

      In fact, RAM requirements [wikipedia.org] have held pretty steady for Windows lately. 2 GB minimum for x64 and 4 GB recommended since Windows 7 in October 2009. 8 GB is probably more than enough for most.

        i was going to say this advice is almost 10 years old, and you can write the same sentence and change the numbers if you go all the way back to dos with windows 3.1 running on it. just say 4mb is minimum 8mb recommend--16mb is great.

        64mb was overkill (me I had 24mb in that era, due to having two 16s and two 4s populating the ram slots--i upgraded and found i could use half of the previous memory without encountering what enthusiasts cried about as unmatched memory killing performance. i made the extra ram space into a ramdisk and... well multiply it all by 1024 and i still do the same things today)

        I shouldn't need a Computer Degree to get a stable Windows environment. Though, I guess that's the price one pays for using MS?

    Arduinos probably have more power than the average DOS 3.1 machine. Also, please note you can acquire a Rasperry Pi Zero for $5 + Shipping. That Raspberry Pi Zero is definitely more powerful than your average DOS 3.1 machine. There's also the Raspberry Pi Zero W that has wireless and bluetooth built-in for $10 + shipping. The Zero W shooting 1080p video with a Pi Camera Module draws approximately 1.1W. I used to hold on to old hardware, because what if I wanted to try XYZ thing. I don't do that anymore, because the power savings alone are worth using something different. Also, DOSBox or FreeDOS will almost certainly be good enough. I do have an old Thinkpad A21m that's still kicking it, though. I put Lubuntu on that thing and it's pretty nice. Though, it's most assuredly out of date.
