Before the announcement of Haswell processor left more than a week, Intel has already began talking about the strengths of the new platform.  According to Intel Spring Analyst Summit, a major cause of stagnation in the computer industry consider the absence of inducing the purchase of new computers factors.  The release of Haswell processor, in their opinion, will create the necessary incentives - both in terms of new form factors, as well as in terms of battery life, security, and responsiveness.

According to Intel representatives  , available data opinion polls suggest that 85% of tablet owners continue to use their PC.  Moreover, they are going to upgrade their own computers.  Of course, the experience of working with the tablet form new needs.  In particular, one of the areas of for this audience modernization - is the acquisition of a computer or a laptop with a touchscreen interface.

In the initial state GeForce GTX Titan was poorly adapted to limit overclocking, but equipping it with modded power system allowed its full potential.  

EPower , which was designed by EVGA with the direct participation of talented engineer and well-known overclocker Ilya Tsemenko (TiN).  Now, on the pages of KingpinCooling forum he told about plans to transform GeForce GTX 780 in the new record holder . Ilya has published a step by step illustrated guide to turning GeForce GTX 780 reference design in extreme overclocking champion.

Currently there were four instances of GeForce GTX 780, they are already installed tanks for liquid nitrogen.

Apple online store  in the United States offer reduced under the supervision of the company's products, which are already  in use.  It should be noted that this week restored iPad mini and iPad 4 in addition dropped from $ 20 to $ 90.

Thus, the restored iPad mini in the most modest configuration with 16 GB of memory is available for $ 279 - $ 329 new costs.  In the case of the iPad 4 more substantial savings: If the low-end model with 16 GB of memory, you can save only $ 80, the eldest with 64 GB of memory and a built-in modem is cheaper by $ 140.  All refurbished Apple tablet equipped with new case, new battery, new packaging and supplied with regular accessories, as well as proprietary-year warranty.

Although up to the announcement of the new generation Apple tablet, according to unofficial information available, there is still a few months, the company may be using the above discounts to get rid of quickly returning tablets.  It is noteworthy that some U.S. retailers offering the iPhone 5 with a $ 50 discount off the regular price.  However, competing smartphones Samsung also fell by that amount, .  Especially since the 50-dollar discount is available only at the conclusion of a two-year contract with a local operator.

Attempts to ARM partners to promote their development in the server market have a chance to succeed in the coming years, as ARM introduced the 64-bit architecture.  In particular, AMD intends next year to start the supply of processors Opteron, having blocks with ARM architecture .  Processors with such architecture is attributed to high energy efficiency and good scalability in a number of standard loads.

According to a study of experts Barcelona Supercomputing Center (BSC), which was devoted to the availability of mobile processors with ARM architecture for use in supercomputers.  The study's authors refer to the historical pattern, according to which a cheap and energy-efficient processors eventually displace the more complex specialty processors of supercomputers.  If at the beginning of the nineties list of the 500 fastest supercomputers in the world consisted primarily of systems based on vector processors, then they later gave way to the processor RISC-based architecture.  The latter, in turn, yielded to the pressure of a massive x86-compatible processors Xeon and Opteron.  Now they are used in more than 400 systems of the Top 500 list.

Accordingly, the authors of the study predict a cheaper mobile processors with ARM architecture, too, will begin to replace traditional server processors of supercomputers.  First, though inferior in performance, but have a lower initial cost and power consumption.  BSC has built experimental servers based on the NVIDIA Tegra 3 (Cortex-A9) and Samsung Exynos 5 (Cortex-A15) - the latter proved to 1.7 times faster in single-threaded tasks.  As a base for comparison with the x86-compatible architecture used mobile processor Intel Core i7-2760QM.  The authors of the experiment found that in terms of the energy efficiency a single core ARM processors are superior to x86 platform, and on the speed at equal frequencies about similar .  

Of course, the main obstacle to the expansion of the ARM-architecture is still underdeveloped infrastructure.  While in the market is no 64-bit processor ARM architecture , no applications are compatible with them, there are no mechanisms for error correction and discharge networks used interfaces are not standardized.  However, the authors of the publication concludes that mobile processors with ARM-architecture is required to work in supercomputers quality.  Their penetration into this segment - only a matter of time.
