Is Xeon 5x the speed of Xeon? How do those institutions ever upgrade then?
I think what you're really saying is Power9 needs to be 5x the speed compared to Xeons from 5 years ago or whatever. Because otherwise new Xeons would never replace older Xeons either, following that logic.
Power9 and other Intel alternatives just need to show 1.5x-2x the value compared to Intel's latest.
- nine_k 9y agoI read it as the following: "If you offer a machine that has N times the performance of the current industry standard machine, it should cost cost kN times the current industry standard machine where k < 1". That is, there's no incentive to pay the cost of switching if you don't save any money in the longer term. And that "longer term" is usually but a few years.
- hpcjoe 9y agoYes, this was what I was trying to convey. Customers (when I ran my company) explained it to me in terms of Moore's law. They could wait 5 years for 1 order of magnitude (back then). Or I could deliver that (near) order of magnitude now, but the economics still had to work out. So kN where this was not tremendously different in TCO than existing solutions. kN might be 1.25x existing costs for 5x performance today. This was an actual example given to me. Customer then indicated that they'd be quite interested in performance at that price. k*N >> 2x, and it got problematic. So I had my range to work with.
