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 …

Sapphire Offers an Alternative Radeon HD 7870 GHz Graphics Card

Sapphire Technology, a renowned supplier of graphics solutions, has added an alternative model of AMD Radeon HD 7870 GHz Edition to its graphics cards model line. The new model is primarily notable by the integration of a two-slot Dual-X cooler that facilitated the process of entitling: Sapphire Radeon HD 7870 GHz Dual-X Edition. This cooler consists of a voluminous aluminum heatsink, a couple of large fans, and a few copper heat pipes which are covered by a plastic lid.



Graphics card Sapphire Radeon HD 7870 GHz Dual-X Edition is based on Pitcairn chip with 1280 current processors; it is developed under 28 nm technological process and Graphics Core Next architecture. The core is able to operate at the nominal 1000 MHz frequency. Blue printed circuit board is the heart of the adapter. PCB is designed particularly for PCI-e 3.0 x16 bus and houses 2GB of GDDR5 memory with 256-bit interface. The memory is capable to achieve the clock frequency of 4800 MHz.

Deepcool Unveils Plans for Quanta DQ Power Supply Units

Deepcool Industries Co. Ltd., is about to launch a couple of new power supply units, codenamed Quanta DQ1000 and Quanta DQ1250. Both models feature 150x200x86 mm dimensions and come with a semi-modular design (24-pin ATX and 8-pin EPS cables are non-detachable). As seen from the codenames, they offer 1000 W and 1250 W power that is quite enough to energize the most demanding gaming systems.



PSU Deepcool Quanta DQ1000 might boast the availability of 80 Plus Gold certificate, due to 92% efficiency level. This unit comes with a single +12V rail, which produces up to 999 W power at 83.3 A current. In its turn, Quanta DQ1250 has got 80 Plus Platinum certificate, since it is able to demonstrate up to 94% efficiency at the highest loading. Unlike its companion, this model houses two +12V rails with 45 A and 65 A current for both.


The list of detachable cables includes eight SATA, three Molex, one Berg, and four 8-pin PCI Express. All the cables might be neatly managed on the …
