There were 14nm phi's. While there are likely a few workloads the phi performed well on, it's days as a dedicated accelerator were clearly numbered with the increased core counts we're seeing today. The phi only lists at 112 GB/s memory bandwidth.

- dragontamer 6y agoThere were many models of Phi. https://insidehpc.com/2016/01/mcdram/ https://insidehpc.com/2016/01/mcdram/ This one with MCDRAM (aka: HMC RAM from Micron) was well known to hit 400GBps bandwidth. It does seem like this model is 14nm, as you've said. So I stand corrected on the process node for Xeon Phi: 14nm is more realistic representation, at least for the HMC model I was thinking about.
- rbanffy 6y agoI was thinking about the MCDRAM models when I thought about a Phi developer workstation. Having no external RAM would allow a very simple design. It would be no NUC, however - it's still a 300+W part.
