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.

Samsung Galaxy S6 & S6 Edge Review: Samsung finally delivers on design

The launch of the Galaxy S6 is one of the most important for Samsung in a long time, and this time around there’s not just one flagship, but two: the company has released a curved-display Edge variant. Both come with a 5.1-inch Super AMOLED display with a top-end 1440p resolution, a brand new Exynos 7 Octa 7420 SoC, and a 16-megapixel optically stabilized camera. Unlike with the past three generations of Galaxy flagships, there’s no Qualcomm model in sight.

Work and Play? Razer Blade Pro (2015) Review

The Razer Blade has earned a solid reputation among those looking for a lightweight gaming notebook, but what if your mobile gaming rig also doubles as your productivity machine?

Asrock X99E-ITX/ac Review: A uniquely capable Mini-ITX motherboard

Asrock doesn't mind taking chances with design and proof of this is the X99E-ITX/ac, the first and only Mini-ITX X99 motherboard to support an Intel Extreme-series chipset. Though we were skeptical at first, it delivers the performance of a full-sized EATX X99 board in a 170mm x 170mm package that manages to carry enthusiast trappings from Wi-Fi & Bluetooth to SATA Express & M.2 connectivity.

Mortal Kombat X Review: Bringing fresh blood to the classic franchise

This is a next-generation Mortal Kombat in more ways than one. It features new characters, some of whom are the sons and daughters of classic Kombatants like Johnny Cage and Jax Briggs. More gore, but also more emotional plot points. You get the sense that Netherrealm is trying to infuse fresh blood into their franchise while simultaneously courting acclaim from the world of hyper-competent pro-competition players. Mostly, the ambition pays off.

No Expense Spared: The ridiculously powerful MicroATX PC

Every enthusiast dreams of building a budgetless rig with nothing but the best hardware. Thus, we're throwing caution to the wind by cramming the priciest and most powerful gaming hardware into a 32L chassis. The end result should be a ridiculously powerful mATX system ready for any and all tasks. With the hardware cost coming in at around $2,750 without a keyboard/mouse or monitor, this is an affair with no expenses spared.

Grand Theft Auto V Benchmarked, Performance Review

PC gamers are finally getting their chance to play the latest entry in the Grand Theft Auto series. Rockstar has made many improvements to the PC version, including increased resolution and graphical detail, denser traffic, greater draw distances, upgraded AI, new wildlife, and advanced weather and damage effects. So far GTA V looks to be truly optimized for PC and we are set to test the heck of it now.

Crucial MX200 1TB & BX100 500GB SSD Review: Replacing the venerable MX100

Crucial SSDs have been among the most reliable and best performing on the market, with last year's MX100 being their greatest hit. Its successor, the MX200 arrived only six months later and along with it Crucial also introduced the even more affordable BX100 series and a new SSD toolbox software. On today's menu is the beefy 1TB MX200 ($470) along with the 500GB BX100 ($190).

LG G Flex 2 Review: Top-notch hardware, same curved gimmick-ness

While similar in shape to the original, the new LG G Flex 2 features a more reasonable 5.5-inch display while maintaining the flexibility to bend in certain circumstances. LG is packing in all the latest and greatest hardware: Snapdragon 810 SoC, 1080p display and a 13MP camera with laser-assisted autofocus and OIS. It's still a niche flagship, but the question remains, is the curved G Flex 2 worth it?

Intel Core i3 vs. Core i5 vs. Core i7: What do you get by spending more?

With desktop CPU prices ranging from as little as $60 to over $600 there are options for everyone wanting to buy or build a new Intel system. The Core i3 is intended as entry-level, the Core i5 is geared for mainstream usage, and the mighty Core i7 is meant for high-end systems and enthusiasts. But what do you get by spending more? Here's your answer.

Logitech MX Master Wireless Mouse Review: A worthy successor

The original MX Performance was announced back in August of 2009 as Logitech's answer to Microsoft's 'BlueTrack' mouse sensor technology. For $100, it was a pretty good deal back back then, being the first mouse from Logitech feature its Darkfield laser and Unifying USB micro-receiver. Now six years later, Logitech wants to recapture the magic of its MX Performance with the 'MX Master', which is aimed at those who want a high-end mouse that isn't designed for gaming.

Samsung 850 Evo M.2 & mSATA Review: V-NAND comes to more form factors

Equipped with 3D TLC NAND, Samsung's 'V-NAND'-based 850 Evo series released last December, stacks layer upon layer of transistors, improving density, endurance and performance, while lowering production costs. Today we have two similarly new drives that focus on different form factors. The 850 Evo mSATA will appeal to compact PC users, while the M.2 will be more sought after by power users.

Battlefield Hardline Benchmarked, Performance Review

Battlefield Hardline showed superb graphics and smooth gameplay when we benchmarked it during last month's week-long public beta, and while the good news was that the game could be played on fairly modest hardware, it didn't quite display Battlefield 4's wow-factor. Developed by Visceral Games, the retail version Hardline is now available and we are back to rerun all the beta tests along with others to see how the frame rates have changed from beta to retail.

HTC One M9 Review: Solid Evolution

HTC’s signature metal body makes a repeated appearance on the new One M9 and it looks absolutely fantastic. The two-tone, two-finish design adds an extra bit of flare to the well-crafted, premium build, making this phone one of the most attractive on the market today. But where does One M9 fall short and where is it better than the competition?
