I’ve found a link to some numbers on IBM’s site. They list a bunch of IBM products, including the Power 750 Express servers and IBM’s newest servers, the Power 795.
If I’m reading these specs correctly, Watson’s 2880 Power 7 cores and 16 TB of Ram that it got from 90 servers can be duplicated by 12 Power 795 servers. Is that actually accurate? Each 795 can hold 256 cores, and 256*12> 2880. And the ram is easy, because each 795 can hold 8 TB of Ram. I believe AIX® rPerf Ranges also indicate substantial improvement: Power 750 has 52.29 – 334.97, and Power 795 has 273.51 – 2978.16 But there might be other computer architecture specs I’m not reading correctly and some of it is vague, like the reference to “Use I/O drawers.”
Unfortunately, I don’t see power consumption figures for the 795, or I could check the power consumption of a 795 against the 750 and see how wattage efficiency changed. The 795 appears better than the 750, but if it’s just bigger, it’s a moot point. It does appear somewhat bigger, but I’m having a hard time breaking down how much of those improvements are from size and how much of that improvement is from other factors.
