Thai Le, Intel, How Intel AVX2 Improves Performance on Server Applications, here
The latest Intel® Xeon® processor E5 v3 family includes a feature called Intel® Advanced Vector Extensions 2 (Intel® AVX2), which can potentially improve application performance related to high performance computing, databases, and video processing. Here we will explain the context, and provide an example of how using Intel® AVX2 improved performance for a commonly known benchmark.
SiSoftware, Benchmarks: Intel Mobile Haswell (CrystalWell): Memory Sub-SYSTEM, here.
Haswell (HSW) is the next generation Core “APU” from Intel (v4 2013) replacing the current Ivy Bridge (IVB) (v3 2012) line-up in both desktop and mobile platforms. While built on the same 22nm process as Ivy, it is a major architecture refresh, thus it introduces new instruction sets (AVX2, FMA3) and features. Not socket compatible (LGA 1150 desktop), so existing systems cannot be upgraded.
