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 …

Enermax Equips NAXN ADV Units with Flat Cables

Enermax, a well-known manufacturer of various PC components, has recently introduced a new line of power supply units that are considered to be a more elaborate follower of NAXN series launched in 2011. A new line has been entitled NAXN ADV and already acquired 80 Plus Bronze certificate. Models, that entered the series, inherited a lot of similar features from their predecessors, nonetheless, they can boast a range of distinguishing parameters.

Thus, one of the most peculiar features pertained to NAXN ADV units is the implementation of absolutely flat cables, including the main power cable with 24-pin connector, cables with PCI Express connectors for 3D cards, as well as cables with sockets for the connection of drives.

Besides flat structure, all cables are quite flexible. According to the manufacturer's words, such layout facilitates their mounting and eliminates the problem of their confusion within the case. In its turn, proper cable management enhances the airflow …

Company LEPA produces new power supplies B-series

LEPA introduced three new power supplies — B650-SA, B700-MAS and the B800-MAS, which will replace older models B750-MA, and B850-MA. Newcomers have been certified with 80 Plus Bronze (efficiency of 88% of the networks 230V), and met the standards of ATX12V v2.3 and EPS12V 2.92, and positioned as solutions for gamers and owners of GPU configurations SLI and CrossFire, workstations and small servers.

New items are equipped with inverter DC-DC (to improve stability), have the topology of Double Forward Circuit, as well as high-quality electrical components: solid capacitors and heat resistant (105 ° C) capacitors made in Japan.

Active cooling LEPA B700-MAS/B800-MAS is provided by 140-mm fan on double bearings. The model B650-SA has a fan size of 120 mm. The intensity depends on the rates of temperature sensor. Power Cables PCI-E, SATA and Molex flat are detachable. The main ATX 24-pin, as well as “CPU” EPS12V 8-pin are collected in a nylon sheath. LEPA B650-SA has …
