Unrelated but anyone knows how the market for ARM chips look like? Are the offerings from Qualcomm and Cavium any good?

- thisisit 9y agoThanks. Cavium ones are just mentioned in passing. any links for the ThunderX2 line too?
- lsc 9y agoMy info is several years old, but it was super frustrating, because both amd and cavium claimed to be selling ARM servers, and I was stoked to sell arm-based VPSs, and I even had an ARM/linux friend on hand to help out... but nobody would sell me any. Maybe they were only selling in lots over 100 or something? Maybe my sales contacts weren't good enough. It would be interesting to hear from someone who has taken delivery of one of these units.
- rwmj 9y agoYou've been able to buy Cavium ThunderX (v1) for a long time. I wouldn't recommend them because of poor single thread performance and the fact that ThunderX2 is nearly there, but for example: https://www.avantek.co.uk/arm-server-h270-t70/ https://www.avantek.co.uk/arm-server-h270-t70/ Qualcomm Amberwing is also available to buy, although at a somewhat eye-watering price.
- dnautics 9y agoI was told that if you are holding out for x2 good luck since most are already presold to big players.
- rwmj 9y agoThe Qualcomm Amberwing absolutely rocks. Fastest server I've used for a while. Edit: Teaser picture: https://rwmj.wordpress.com/2017/11/20/make-j46-kernel-builds-on-qualcomm-amberwing/ https://rwmj.wordpress.com/2017/11/20/make-j46-kernel-builds... As usual because of NDAs I'm not allowed to publish benchmarks.
- trhway 9y agocurious - why parallel build with about 32 compiler (ie. cpu heavy) instances with total 93% user cpu load (and no wait, etc) shows individual processes at 48% cpu max on that machine (which i suppose is at least 24 cores and probably 48)? In that situation on Lintel the top processes are usually shown as close to 100% cpu. Is it just a quirk of system accounting on those ARMs? Or do all these compiler processes contend on something (like for example may be memory bus)?
- wyldfire 9y agoIt is fairly unlikely to saturate 46 CPUs with a kernel compile. However it's probably much better off than if it were C++ source. Yes, I'd absolutely expect memory contention when it's not I/O bound.
- rbanffy 9y agoIs it generally available? I'd love to play with one as my main workstation.
