Differences from POWER8?
I can't find much information about POWER8E, is this what IBM refers to as POWER8 with Nvidia NVLink? I get no search results for POWER8E on the OpenPOWER Foundation website. Most of the web results for "POWER8E" are the result of users running
cat /proc/cpuinfo, even though they refer to the processor as plainly POWER8 elsewhere. This Phoronix article for example, does not suggest that POWER8E is any different from POWER8. Torpcoms (talk) 11:36, 2 January 2018 (CST)
- This is especially strange, because the POWER8 page indicates the previous architecture as POWER7 not POWER7+. Unlike POWER8E, the POWER7+ distinction is clearly recognised by IBM. Torpcoms (talk) 11:45, 2 January 2018 (CST)
- Yes, this is "POWER8 with Nvidia NVLink". We have no direct experience with this module, aside from the fact that it does not work (or even fit) in the standard POWER8 socket. This was a stopgap module on the path to POWER9, and does not seem widely deployed? In any case, you are correct, there was a typo and POWER7+ should have been the previous processor.
