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 …

Xeon Phi: Revolutionary Offer from Intel Developers

Intel Corporation has made a resolute step towards the improvement of performance demonstrated by ‘supercomputers’. Its new Intel Xeon Phi is called to create a real revolution in the IT world, offering unmatched performance showings on activities with the high parallelism degree. This is supposed to bring supercomputers to the new level by means of enlarging the performance levels from TFLOP to EXAFLOP. Upon the whole, Xeon Phi is the name which will be used for further line of products based on Intel MIC architecture.



Xeon Phi coprocessors are sure to enable the transmission of the reduced data via PCI slots and will primarily be applied to dedicated coprocessors. The sales start is designated to the end of the current year, and the first products presented in the market will be items which belong to Knights Corner series. According to the Intel developers’ words, Xeon Phi will firstly replenish the series of central processors Intel Xeon E5-2600/4600; further on, the …

SilverStone Heligon HE01 - a new super-cooler

The Taiwanese company introduced a bulky cooler SilverStone Heligon HE01, which is designed to cool down more or less all types of modern CPUs — from Intel LGA775 up to LGA2011 and from AMD AM2 to AMD AM3 + / FM2.



The construction does not weigh less than 1.1 kg, since in addition to two-part radiator (926 g) it is equipped with fan of 140x140x38 mm size. Linear dimensions of Heligon HE01 are 140 mm in width, 119 mm in length and 160 mm in height. Staples that hold the fan, take a few millimetres of space.


The thickness of a pair of «towers», joined by six nickel-plated copper heat pipes with a diameter of 6 mm, is uneven. The intense air flow passes successively through a thin array of aluminium fins, and then through the fan, afterwards through a larger section of the radiator. Copper base with nickel cover is protected with a film from scratches.


The manufacturer claims that Heligon HE01 will cope with the withdrawal of 300 watts of heating power.
