Exclusive: BCLK overclocking non-K Intel Skylake CPUs is now possible, tested here

In overclocking circles it was recently noted that BCLK (base clock) overclocking might become a possibility in Skylake processors, but it would be up to motherboard manufacturers to circumvent Intel's restrictions. Last night Asrock contacted us with an updated BIOS that enabled this. We jumped at the opportunity and have already tested and benched a Core i3-6100 Skylake CPU with a 1GHz overclock (4.7GHz) on air cooling.

The Best CPU for the Money: Intel Core i3-6100 vs. i3-4360, i5-4430 & AMD FX-8320E

The FX-8320E has been AMD's go-to option for budget quad-core computing without integrated graphics for a few months now. But the landscape has shifted on Intel's side with the arrival of its new Skylake-based Core i3 and Pentium processors. After being disappointed in August by the marginal performance between Skylake and Haswell Core i7s, we're interested in seeing how the i3-6100 stacks up against the older i3-4360, as well as the i5-4430 and the overclocked FX-8320E.

Fallout 4 Benchmarked, Performance Review

Set in Boston 200 years after a nuclear war, Fallout 4 is the series' fifth major instalment, based on a modified version of the Creation Engine first used for Skyrim in 2011. Many eager PC gamers are undoubtedly waiting to see how the game looks and performs so we've put together our usual performance analysis to give you an idea of it should play on your system.

Samsung SSD 950 Pro M.2 performance preview

While M.2 drives are nothing new to the PC community, many manufacturers like Samsung have been holding off on developing drives for the retail market until more devices were able to utilize them. We have finally reached the point where…

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?

Batman: Arkham Knight Benchmarked, Performance Review

Batman: Arkham Knight, the fourth entry in Warner Brother's Batman: Arkham series, is based on the same Unreal Engine 3 as its predecessor and an Nvidia-sponsored title. Favoring one camp of GPUs is hardly the least contentious way to launch a new game, however it seems this release would have rattled cages regardless. Countless Nvidia and AMD users have expressed anger about Arkham Knight's performance and stuttering issues. Here's what we found in our tests.

The Witcher 3: Wild Hunt Benchmarked, Performance Review

The Witcher 3 is the New Crysis We have tested nineteen DirectX 11 graphics cards to find out how the game performs in both AMD and Nvidia hardware. After extensive testing it's clear why The Witcher 3: Wild Hunt doesn't look nearly as good as the 2013's trailer: even in its current uber beautiful form, the game is simply too demanding for today's hardware.

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.
