I think the comparison is still quite dangerous: possibly unfair, probably telling little about current hardware. The power efficiency and core count has increased tremendously on Intel CPUs with Sandy Bridge first and late with Haswell. Fo

In the project I work on our style also requires block-parens. Sometimes it feels unnecessary, but it does make up in terms of consistency: it's easy to glance through the code and inspect the conditions only. I got used to this quite

Not sure if they fixed it in the meantime, but it work for me right now with client version 4.3.0.37.

The Boost-ed frequency depends on multiple factors, including the number of cores used, power consumption, current, temperature and even the type of instructions executed (e.g. AVX instructions trigger a drop in frequency on Xeon cores, not

Apparently the judge is ordering Apple to essentially disable all features that prevent or slow down brute-forcing, updates and quotes here: https://www.techdirt.com/articles/20160216/17393733617/no-ju...

Performance/watt is improving greatly! Look at this plot [1] from about 2013 showing the theoretical perf/w of CPUs up to Ivy Bridge, and GPUs up to NVIDIA Kepler GK110 and AMD Hawaii XT. Since than both Intel with Haswell (and Sk

Not just thermal reasons! For instance, keeping caches coherent across so many cores is a great challenge. That's what Intel was experimenting with on Knights Corner - and many think they screwed it up quite a bit - with the ring bus +

That may be true for simple operations on aligned buffers, and nice regular computation in general. Anything slightly complex will throw off the compiler and result in suboptimal performance in the best case, none or stupid vectorization th
