The most powerful graphics card NVIDIA GeForce Titan Z

The most powerful contemporary graphics NVIDIA GeForce Titan Z does come in retail channels. Once the accelerator is not came out in due time, there were concerns about possible freezing the project. But they have not been confirmed.

This card based on the well-known processor GK110, which are equipped with the most advanced accelerators NVIDIA, two of them here. Accordingly, she received twice the number of CUDA-cores - 5760. Memory capacity also doubled and reached 12 GB bandwidth and 672 Gb / s. Memory bus retained 384-bit interface, but it became a two-channel. Processor clock speed is 700 MHz (uniprocessor Titan Black - 889 MHz), while the performance of GTX Titan Z is 8 teraflops.

Other features include 480 texture units and 96 render blocks, API-interfaces support DirectX 11.2 and OpenGL 4.3, CUDA technology and PhysX, and the availability of ports Dual DVI, DisplayPort and HDMI. Power consumption is 375 W.

At the request of NVIDIA, card can work even in the most complicated multi-monitor configurations, including displays with support for 4K-resolution.

This card can buy in retail channels.

New hard disk drive Buffalo HD-PGDU3

Interface USB 3.0 has more bandwidth so that traditional external HDD is unable to use it fully. Partly solve the problem of solid state drives, but they are still much more expensive while their magnetic counterparts. Nevertheless, manufacturers continue to seek ways to improve the performance of hard drives.

As an option - installation on an external drive intermediate cache, which is temporarily stored information when transferring files to / from your computer, laptop or other device. Buffalo to take full advantage of this opportunity to fit in its new product, HD-PGDU3, a gigabyte of fast DDR3-memory.

When disk working HD-PGDU3 uses DDR3-memory as a cache, which instantly fall (most copied) data. Then the files are moved to the hard drive in the background. It is noteworthy that the information is not removed from the cache even in the event of a power drive - it manufacturer has provided a small battery, which is enough to avoid losing data in the absence of electricity. For the convenience of users on HD-PGDU3 has LED-battery indicator.

In volume terms, the HD-PGDU3 available in two versions with 500 GB and 1 TB of storage space. This is a very interesting construction.

New virtual keyboard for smartphones and tablets

Seemed more recently fiction elements of mobile devices is becoming a reality. Thus Galaxy S4 have not received a laser keyboard, and today it is already possible to equip any mobile device. For example, due to the novelty of the R2-D2 of Imp.

R2-D2, as the name implies, is in the form of the famous figures of the droid from "Star Wars." It is installed in front of the smartphone or tablet, and projects on any horizontal surface light virtual keyboard, uttering at the same distinctive sound. The robot is connected to a mobile device wirelessly Bluetooth 3.0, so it can be used for distances up to 10 m. Of course you can use it with usual computer.

It is noteworthy that it is compatible not only with Android (version 4.0 or later), but c and other popular operating systems, including Windows 7/8, Mac OS X and iOS. Inside R2-D2 mounted battery with 660 mAh battery that can be recharged via microUSB-port.

The exact date of sales is unknown. But promised that the new product will be on the market.

Newest graphics accelerator NVIDIA GTX 880

Many laptops from different manufacturers has graphics accelerators NVIDIA 800 series. Among them are mean most powerful model GTX 880M. Now NVIDIA prepare to release GTX 880 for usual computers.

NVIDIA started shipping engineering samples of GTX 880 from one of the Chinese factories to the Indian test lab. This novelty will be equipped with 8 GB of memory. Its base is chip GM204, which will replace the current GK104.

Among other features GTX 880 are 3200 CUDA-cores and 256-bit memory interface GDDR5. Level of performance will be 5,7 teraflops. Most powerful for today consumer card NVIDIA GTX Titan Black Edition has 6 GB of memory and 2880 CUDA-cores. This gpahics accelerator will be more powerfull than modern graphic cards.

SanDisk releases 4-terabyte SSD-drive Optimus Max

The company released the SanDisk SSD capacity of 4 TB and thereby reduced the maximum distance between the traditional HDD and SSD. The novelty is not focused on ordinary consumers, but the business sector.

This drive was named Optimus Max. In the sequential read / write mode speed approximately 400 MB/s. Drive is equipped with error correction technology, data protection and disaster recovery. Furthermore, it maintains one to three complete rewrites information stored on it during the day.


Drive is manufactured by new SSD 19 nm technology. SSD uses SAS interface 6 GB/s.


The company wants to produce in the future SSDs volume 6 TB and 8 TB. Exact date sales are not reported.

NVIDIA preparing to release GeForce GT 705, GT 710 and GT 720 videoadapters. New items will not differ significantly from the videoadapters GeForce GT 620 and GT 630.

GeForce GT 705 will be have: graphic processor GF119, 48 cores CUDA, 64-bit memory bus, 1 GB DDR3 RAM, core frequency 810 MHz, RAM frequency 1796 MHz.

GeForce GT 710 will be have: graphic processor GK208, 192 cores CUDA, 64-bit memory bus, 512 MB DDR3, core frequency 823 MHz, RAM frequency 1800 MHz.

GeForce GT 720 will be have: graphic processor GK208, 384 cores CUDA, 64-bit memory bus, 1 GB DDR3 RAM, core frequency 902 MHz, RAM frequency 1800 MHz.

Videocards are based on new architectures.

How to install linux easy

Do you know the operating system Linux? May be you tried to install or already work in it. But many people would like to try Linux, but they are afraid to damage the data on the hard drive, and think that they can't install the system.

Then download Ubuntu linux desktop. After that, burn image ISO on DVD, or if you will be use virtual machine after creation machine attache image as DVD drive. Run machine. Don't forget create virtual hard drive and set RAM size about 512 MB (depends of the size on RAM, but less is not recommended).

Insert DVD into drive and set in BIOS boot from DVD. Or, if you use virtual machine, start.

You will see boot menu. Select Install Ubuntu.

You will be prompted to select the language. Continue.

In the next step installer show requirements to hard drive and checks Internet connection. Check the box "Install this third-party software", in this case you can play MP3 and some types video. Continue.

 Then you will see installation type. Select "Sometimes else".

If you have partitions on hard drive it will be shown. In this case hard drive is empty. You can resize, delete or create new partitions. You need free space at minimum 5,9 GB.

This warning means, that partition table will be removed.

Continue.

Create the /home partition. Size depends on size your personal files in home directory.

Create swap area. Size depends on size of RAM (usually 2x size of RAM).

    Create the /home partition. Size depends on size your personal files in home directory.

  Create root partition.

 Then you will see final partition table. If you are not sure back. If you are sure that all right click "Install now".

Select your location.
