Then and Now: A decade of Intel CPUs compared, from Conroe to Haswell

Take a look back at how Intel CPUs have progressed over the years. We're testing and comparing the original Core 2 Duo CPUs against the Nehalem-based Core i5-760 and Core i7-870, the Sandy Bridge Core i5-2500K and Core i7-2700K chips, and then to the current generation Haswell Celeron, Pentium, Core i3, Core i5 and Core i7 parts.

AMD launches another desktop APU, the A8-7670K

AMD launches another desktop APU, the A8-7670K

While Intel has dominated the high-performance CPU market for years, AMD continues to provide value to those on a budget with their reasonably attractive range of APUs. Today, the company has announced a new APU, the A8-7670K, that slots into…

Intel Core i7-5775C Review: Broadwell is off to a rough start on the desktop

Broadwell is the 14nm die shrink of Haswell, bringing a smaller die and lower power consumption. As is often the case with Intel’s ‘Tick’ updates, a few minor tweaks have also been applied, while remaining on the existing LGA1150 platform. Today we have the flagship model on hand, the Core i7-5775C, and its BGA version, the Core i7-5775R. Both are nearly identical save for the price and a slightly higher Turbo frequency on the BGA model.

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.

Best CPU for a budget gaming PC: Athlon X4 860K vs. Pentium G3258

The most affordable build in our recent PC buying guide update caught the attention of many. At around $500, it's ideal for everyday computing with some lightweight gaming. If you're adding a dedicated GPU, however, it makes sense to swap our APU pick for a cheaper CPU, with the saving going towards graphics. We paired two $70 CPUs with the GTX 960 and R9 285 in 20 of the most popular AAA titles, to find out which one is best for gamers on a budget.

Intel Celeron N3050 & Pentium N3700 Review: Entry-level "Braswell" SoCs for small desktops

Intel's new Braswell SoCs promise to be faster across the board while also consuming less power than Bay Trail. The new chips are manufactured using Intel's 14nm process and include the mobile Celeron N3000, N3050, N3150, and Pentium N3700. The last three are meant for desktop systems and today we have the N3050 and N3700 in hand for testing.

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.
