I want to comment that the result for this single-threaded benchmark that tests computations with large integers is a nice surprise.

Even if libgmp is not optimized for Zen yet, the result is practically equal in IPC with Haswell.

This is a huge progress for AMD. Whoever dares to use the word "fiasco" about Zen has no idea about what he is talking.

From the beginning of 2003 (Opteron introduction) until the beginning of 2011 (Sandy Bridge introduction), the AMD processors were the leaders for computations with large integers.

That changed dramatically in 2011, when Sandy Bridge included an improved integer multiplier, but Bulldozer replaced the decent multiplier used in the previous AMD generation with a much slower one. I could never understand that AMD design decision. It was plain stupid, as the area & power saved so could not be significant.



From 2011 until now, the Intel processors got better and better, while the AMD processors (and the ARM processors) remained very far behind them for computations with large integers.


The fact that AMD processors are for sure competitive again is good news.
