How much faster is “D-Wave Two” compared to its predecessor?

I don't have any specific task or algorithm in mind, so depending on how they were tested – Is there any research which shows just how the D-Wave Two computer was faster (in terms of computation performance) than its predecessor (D-Wave One)?

• What do you mean by "computation performance"? Using which benchmarks (e.g. algorithms, tasks, etc)? – nbro Mar 12 '18 at 20:26
• Whatever tasks/algorithms they were tested against. – kenorb Mar 12 '18 at 20:27
• You may specify that in your question. Even better, you may do a little research regarding the topic and include a few details in your question. – nbro Mar 12 '18 at 20:29
• Personally, I feel this would be a much better question if, instead of talking about 'computational performance' (which isn't well defined, although there are certainly numerous good possible questions in this area), you either just ask about speed of qubit initialisation, a single anneal, followed by a measurement or find a much more specific question about computational performance – Mithrandir24601 Mar 12 '18 at 21:03
• I think this question should be edited to describe what precise comparison is desired. It is just too broad right now to give a real answer. – user1271772 Oct 23 '18 at 21:28

As far as I know the closest answer to your question for applications is given in the recent (still unpublished) work presented at the March meeting by Bibek Pokharel, where he compares graph 3-coloring instances on D-Wave Two, D-Wave 2X and D-Wave 2000Q, all other things staying reasonably equal. The short answer is that all the performance increase is essentially due to the possibility to run single anneals at shorter anneal-time. (e.g. 1$\mu$s instead of 5$\mu$s gives indeed about 5X of performance increase, in terms of time-to-solution (TTS) metric. With respect to 20$\mu$s of D-Wave Two the scaling is different).
