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 …

Presentation of ‘Inconceivable’ Graphics Card GeForce GTX 680 iGame

Graphics card from Colorful Technology company has become a real discovery at the crowned Computex 2012 exhibition. The major peculiarity of new GeForce GTX 680 iGame is seen in the integrated gigantic cooler of passive type which is called to ensure the sufficient heat removal. The developers have exceeded all expectations by presenting the graphics cars with such an original design and elaborate framework.



Passive cooler implemented in GeForce GTX 680 iGame consists of two solid aluminum radiators with the copper heat tubes. Those tubes are joined with a jumper which has other six heat tubes. The radiators are localized at both sides of the motherboard. The graphics card itself is of 15 cm in height; this place is dedicated to the nine expansion slots. The accelerator is based on the advanced Kepler architecture and operates under the layout of GK104 chip with Cuda cores. It employs PCI Express 3.0x16 bus and is equipped with GDDR5 memory of 256 bit interface. A couple of …

Arctic Cooling Intros Two Modifications of Freezer CPU Cooler

Arctic Cooling AG, a well-known Swiss developer of cooling solutions, has recently introduced its newest CPU cooler, Freezer, in two modifications: i11 and A11. Both versions have got tower-like framework, featuring 108x90x130 mm dimensions. The Freezer i11 is compatible with Intel LGA 2011/1156/1155/1150 socket platforms, whereas its companion is intended for AMD Socket FM1, FM2, AM3, AM3+, AM2, and AM2+. To say more, this pair is able to cool down the ‘blaze’ of CPUs with 150 W TDP.



Arctic Freezer i11/A11 consists of an aluminum heatspreader with forty-five plates, three U-shape copper heatpipes, and one 92 mm fan. The heatpipes are thought to support direct contact technology that dramatically improves heat transfer process.


The implemented fan is developed on a fluid dynamic bearing and is equipped with a PWM controller. The latter assures that the blades could change their rotational speed within the ranges from 500 RPM to 2000 RPM. Herein, the maximal airflow …
