New characteristics of co-processors Xeon Phi

For several years, developed Intel Larrabee graphics cards have changed its destiny, and now proudly referred to coprocessors Xeon Phi. The June announcement gave a very rough idea of ​​their characteristics and applications (highly specialized servers and workstations). Now some details will be revealed.



Bboosters Xeon Phi will be available in versions with 57, 60 and 61 core. There are in general 64 computational units, but some of them will be disabled. Depending on the number of cores the cache size varies from 1.8-1.9 MB first level and 28-30,5 MB second. The volume of onboard GDDR5 memory is 3, 6, and 8 GB.


Intel Xeon Phi device will operate on a low clock rate from 600-1100 MHz for the lower 57-core models with 3 and 6 GB of GDDR5, to the 630-1050 MHz or more for the older 60 — and 61-core board with 8 GB of RAM. Effective memory frequency will be in the range of 5-5.5 GHz. Support for dynamic overclocking Turbo Boost will be provided by reasonable balance of …

I-O Data Announces 27-Inch Monitor with the Maximal Resolution

Not so long ago Full HD monitors have been considered a kind of miracle, providing the utmost graphic facilities. This format is nowadays actively implemented in the product lines of many manufacturers, though the price for monitors with Full HD resolution is still biting. Despite this fact, some users feel an acute need for even higher resolution, so I-O Data, a Japanese designer of PC hardware, announced the release of a model with the maximal possible resolution.



Codenamed LCD-MF271CGBR, the monitor features 2560x1440 resolution and 27-inch display. The working display space exceeds the one implemented in monitors with Full HD resolution in 1.8 times. Such specifications offer unmatched graphics effects for the successful accomplishment on rather demanding conditions.


Monitor I-O Data LCD-MF271CGBR is based on IPS array type and is characterized by the following features:

— available video outputs: dual DVI-D, HDMI, DisplayPort, VGA;

— maximal supported …

Lifting the Veil from USB Type-C Bus

Since the launch in 1995, Universal Serial Bus (USB) has proved itself as the most successful ever computing interface. Nowadays tens of billions of electronic devices are connected together due to it. It goes without saying that this bus has outlived a few modifications, each distinguished by higher speed and reliability. Thus, today the community is able to revel in a completely new modification – USB Type-C – that forecasts a lot privileges of connectivity process. Let’s see what users will get with a new bus.



Layout and Connectivity


In physical terms, Type-C is a bit larger than USB 2.0 Micro-B but a bit tinier than binary USB 3.0 Micro-B, featuring 8.34x2.56 mm. Such dimensions enable its connection to the devices of any type, including the thinnest smartphones/tablets. The oval-shaped socket houses 24 contact outputs (to compare: USB 3.0 sockets feature only 9 outputs).


The most outstanding physical peculiarity of Type-C is a symmetric connector that …
