Compare the new Intel v4 (Broadwell) Xeons to their predecessor v3 (Haswell) Xeons

Dual  Intel Xeon E5 2695 v4 Broadwell CPUs  means the Broadwell blade has 72 logical cores. Each Intel Xeon E5-2695 V4 has 18core, 36 thread processor with 45MB L3 cache.

With 2.1GHz base clock speeds and turbo boost speeds up to 3.3GHz, these chips are a significant upgrade to the 14C/ 28T E5-2695 V3 which sported only 35MB L3 cache.

Processor is meant for heavy compute workloads.

We recommend a minimum of 128GB of RAM on any Intel Xeon E5-2600 V4 server


Intel Advanced Vector Extensions 2  (AVX2) Improves Performance on Server Applications. When not using Intel AVX2, Broadwell seems to provide a 4 per cent to 5 per cent increase in performance clock for clock over Haswell. This seems slightly higher with Intel AVX2, with Broadwell showing an 8 per cent increase over Haswell.

Value for money

If Broadwell versus Haswell seems a little mediocre, let’s compare Broadwell to Intel’s v1 (Sandy Bridge) Xeons. A lot of organisations are looking at upgrading v1 Xeons to v4 Xeons and the jump in speed is actually worth it. Clock for clock, the Broadwells seem to be a little under 20 per cent faster for non-AVX workloads. AVX workloads were considerably faster.

Final Thoughts:
The E5-2695 V4 is about 60% more expensive, per chip, than the E5-2670 V1, yet offers a 2x-3x performance improvement. If you’re running Haswell, there isn’t a huge incentive to upgrade to Broadwell. If, however, you’re running Sandy Bridge or Ivy Bridge Xeons, Broadwell is probably worth your time.
