Water Cooling 101: What to do and what to avoid

Water cooling systems -- whether they are a custom loop or an AIO -- all follow the same basic principles. You have the reservoir, the pump, the radiator, the fans, some tubing, a block (for either the CPU, GPU, or both), and the water itself. After years of working with water cooling kits, here are some important tips to help you get the most out of your system.

Motorola Moto E vs. Samsung Galaxy S6: Here's what that high-end premium gets you

If you’re currently in the market for the best smartphone going around, the $550 Samsung Galaxy S6 should be close to the top of your list. On the other end of the spectrum sits the Moto E (2015), a great entry-level handset from Motorola that can readily be found for $100. But what does that price gap get you? Is the 2015 Moto E just as usable in day to day activities as the Galaxy S6, or is the extra cost of Samsung’s leading smartphone more than justified?

Parallelization Efficiency: Estimating multi-core CPU performance using Amdahl's Law

While frequency is a decent indicator of how well a CPU will perform in some programs, when the ability to use multiple cores is factored in it can get tricky as not all programs are as efficient at using them. Using a mathematical equation called Amdahl's Law you can determine how efficient your program is at using multiple CPU cores (it's parallelization efficiency) and then use that to estimate the performance of different CPU models of similar architecture.
