Radeon R9 390X Benchmarks Leaked
Benchmarks have been leaked that compare the performance of the rumored AMD Radeon 390X and the NVIDIA GeForce GTX Titan X and GTX 980 Ti. The leaks were reported by Chinese site Chiphell and build on previous rumors that AMD would officially announced the card at Computex. The benchmarks were given as a percentage comparison against the Radeon R9 290X. In a 19 game benchmark suite at 4K resolutions the 390X narrowly outperformed the Titan X, while the other NVIDIA cards were beat handily. The Radeon maintained its advantage at lower resolutions as well as in the 3DMark Fire Strike Extreme benchmark. The NVIDIA cards consumed less power than the 390X, but the Radeon still managed to improve on the power consumption of the 290X.

GIGABYTE Announces X99 Champion Series
GIGABYTE has added to the X99 Champion Series, featuring four motherboards including the previously discussed X99 Gaming 5P. Joining the Gaming 5P are the X99-UD4P, X99-UD3P, "and the already famous X99-SOC Champion." VP of the GIGABYTE Motherboard Business Unit Henry Kao described the Champion stating, "Since its launch in January, the GIGABYTE X99-SOC Champion motherboard has become the undisputed performance leader for X99 motherboards with over 30 top overclocking scores under its belt including 10 World Records." Users can install DIMM modules up to 3200MHz or RDIMM modules that provide greater memory density with support for up to 16GB per stick. Reliability was addressed by using an all digital power design featuring IR Digital PWN and IR PowIRstage ICs, Long Lifespan Durable Black Solid Caps, and 6x Gold Plating. Realtek HD Audio was included with a built-in audio amplifier for improved sound.

Latest Windows 10 Preview Includes P2P Support for Windows Update
Screenshots obtained from the latest leaked build of Windows 10 show off that the next Microsoft operating system will feature peer-to-peer support when it comes to Windows Update. While Windows Update itself has been used for some time now to deliver operating system and application updates, the ability to download the updates from sources other than Microsoft’s own servers is completely new. As long as the feature remains included in the final version of Windows 10, users of the operating system will have the choice to download application and operating system updates from Microsoft and PCs on a local network, or from a combination of local PCs, internet PCs, and Microsoft’s own servers.

Superconductivity Observed at Fastest Speed Yet
High speed cameras were first used over one hundred years ago to determine if the hooves of a galloping horse are ever off the ground at the same time. Ever since then, high speed photography has been used to observe a variety of events, and now researchers at the University of British Columbia have developed a new technique to capture the behavior of electrons in superconductors.
Superconductors are materials capable of transmitting electrical currents without resistance, and have been, understandably, of great interest since their discovery. Unfortunately the low temperatures required have limited their use, but by better understanding how the phenomenon occurs, researchers hope to devise room temperatures superconductors. To that end, the UBC researchers combined technologies and techniques to capture the behavior of electrons over just 10 femtoseconds (0.00000000000001 seconds).
The results support the hypothesis that the interactions between one electron and the spin and magnetic pull of the others around it actually delay and mediate electrons interacting with each other.

Silk Used to Make Better Batteries
The world would be a very different place if we had not developed batteries, especially lithium-ion batteries as they have enabled us to create the powerful yet portable devices we rely on every day. As we continue to demand better performance from our devices, we will have to find some way to improve the batteries that power them. As reported by the American Chemical Society in its journal ACS Nano, researchers may have found a solution from silk.
Many modern energy storage technologies rely on graphite electrodes for storing energy, but it has its limits. To push past those limits, the researchers looked to other carbon sources and found a material derived from silk to replace graphite. The carbon-based nanosheets the researchers created have five times the lithium storage capacity as graphite, which means batteries using them could store substantially more power. Of course storing more power means little of the batteries lack stability, but when tested the material survived 10,000 charge/discharge cycles with only a 9% loss.
The process the researchers used to create their prototype batteries and supercapacitors are single-step and can be easily scaled up.

G501 Series Gaming Laptop Announced by ASUS
ASUS has officially announced the G501 series gaming laptop, which offers gamers a premium gaming experience in a highly portable package. The G501 is the latest Republic of Gamers product from ASUS and is powered by a 4th-generation Intel Core i7-4720HQ processor as well as an NVIDIA GeForce GTX 960M graphics card with up to 4GB of GDDR5 video memory. The ASUS G501 features Hyper Cool technology, which consists of separate cooper heatsinks and fans that run independently of each other, to keep both aforementioned components cool during normal and peak operation. With a height of just 20.6mm, the G501 is one of the world’s thinnest gaming laptops available, and its lightweight aluminum construction allows it to weigh just 2.06kg, for non-touchscreen models. The ROG G501 features a 15.6-inch 4K/UHD display, ASUS SonicMaster audio, and can be configured with a PCI Express x4 slot and Intel Thunderbolt technology.

Screenshots Compare Grand Theft Auto V on PS3, PS4, and PC
A wealth of Grand Theft Auto V screenshots have just been released that compare the PS3 and PS4 versions of the game to the PC version, which happens to be running at 4K. The screenshots show just how different the game looks on all three platforms, with the PS4 looking substantially better than the PS3, and PC looking quite good in comparison to the PS4. All of the available screenshots cover a variety of different areas in Grand Theft Auto V, which is still on track to be released on April 14, 2015.
