Google's POWER8 server motherboard

Reporting memory bandwidth in Gb is misleading.

The page you cite here: http://www.intel.com/content/www/us/en/benchmarks/server/xeo...

shows a triad bandwidth (STREAM) of 246,313.60 MB (megabytes) per second which is 240 GB (gigaBYTES) / sec.

If I'm making a mistake I'm sure we can work it out.

That 240GB is on 4 sockets, so corresponds roughly to the 85GB/socket cited above, while the Power7 compared was about half the Intel, so about 50GB/socket, while Power8 is allegedly at 240GB/socket.

Thanks for the clarification. HN took ~30-40 minutes before it would show a reply option for this post, so I went ahead and acknowledged the performance difference in a reply to my original reply (ugh). Anyway, that's great to see such high memory bandwidth per socket, rather than summed over the whole machine.
