Intel Xeon E3-1240L v5 

Released October, 2015
  • 2.1 GHz
  • Quad core

It is clear that Intel has improved AVX efficiency quite a bit.

Perhaps more surprising is that it even performs well in our FP intensive applications.

Intel Xeon E5 Version 3: Up to 18 Haswell EP Cores

by Johan De Gelas |
However, it's not a case of the Haswell's L3 cache being a lot worse: the 20MB L3 cache of the Xeon E5-2667 v3 is only slightly slower than the Xeon E5-2690 and is still faster than the Xeon E5-2697 v2 (30MB).
Of course, those kind of bandwidth numbers only matter for specific HPC benchmarks as the L3 cache (30-45MB L3) will take care of most of the requests.
