I think datacenters will opt for more ARM architectures before introducing liquid at scale. Things like Gravitron and Apple Silicon are changing the landscape there.
- sudosysgen 5y agoGraviton and Apple Silicon still don't offer significant performance per watt improvements versus EPYC. I don't think it will make or break the need for liquid cooling.
- atty 5y agoI’m pretty sure AMD offers perf/watt that is in the ballpark of ARM chips, and I’m guessing Intel, if they ever get on a similar process node again, will be able to get close. None of that changes the need for accelerators though. Nvidia et al want to make the biggest chips they can, and at some point that means water cooling.
- PragmaticPulp 5y agoThe article is mostly about cooling high power, GPU-like accelerator units that consume 400-600W or more. Even with power efficient architectures, the push to scale up core count and increase density will still drive toward more liquid cooling.
- ksec 5y agoYou still have a 280W CPU, instead of 64 Core you now have 128. And if thermals permits they would like 128 x86 Core or 256 ARM Core. Samsung just announced their work of 7xxGB of DDR5 per stick. With a future roadmap of 1TB per stick at a request of hyperscaler. Along with 400W or 500W GPU. And when you have many new packaging technology where each die could be a 100W TDP you quickly run into all sort of thermals limits. And there are all sort of HPC and niche that wants super powerful Server.
