Keep hearing that IBM makes these incredible chips but don’t see anyone using IBM chips. What do they do with them?

You can see the classic terminal look around the store. Banks run a TON of z and i. You'll never see them because they're essentially always in data centers, but I guarantee you interact with them even if it's very non-obvious because there's 50 microservices between the UI and the actual system of record.

I cannot find it now but i remember seeing a cross section of their 40 layer PCB simply so they could get more memory/IO performance to the CPU. POWER may have dropped out of the consumer space but it still has a vital place in servers.

- ternaryoperator 3mo agoTheir line of POWER chips are used in their mainframes
- lizknope 3mo agoNo, their mainframes use the zArch which goes back to the System/360 from 1964. https://en.wikipedia.org/wiki/Z/Architecture https://en.wikipedia.org/wiki/Z/Architecture IBM sells huge servers with POWER architecture CPUs but they are not what people are referring to when they talk about IBM mainframes.
- ternaryoperator 3mo agoAh, thanks for the correction.
- reppap 3mo agoEricsson used a lot of power chips in their telecom hardware 10 years ago at least, haven't worked with their stuff since then so I haven't kept up.
