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 …

Dell Teases a Couple of IPS Monitors: P2417H & P2717H

Dell is about to launch a pair of monitors targeting office PC systems as well as standard home multimedia systems. The P2417H (24-inch display) and the P2717H (27-inch display) are fitted with a high-quality IPS panel with an integrated LED backlight. Both models feature 16:9 aspect ratio and Full HD resolution – 1920x1080 pixels.

The implemented array offers 6 ms response time in GtG environment. The top brightness index makes up 250 & 300 cd/m2 respectively. Both new-comers share the widest possible viewing angles (178/178 degrees) and are able to display up to 16.7 million colors. Static contract index equals to 1000:1, whereas dynamic ratio approximates 4M:1.

Dell P2417H and Dell P2717H boast a rich inventory of external interfaces: a pair of USB 2.0 ports, the same number of USB 3.0 ports, one DisplayPort 1.2, one HDMI 1.4 port, and one analogue D-Sub port. The first display is thought to consume 19 W power, while its companion is known to consume 23 W power.

SilverStone Debuts with SST-ST30SF Power Supply

SilverStone Technology has recently introduced its newest SFX power supply unit. Codenamed SST-ST30SF, it features 125x100x63.5 mm dimensions and weighs 800 g only. The unit is estimated for 300 W power and is capable to demonstrate more than 81% efficiency in 230 V networks. High efficiency level allowed the model to gain 80Plus Bronze certificate.

The most uncommon feature ascribed to SST-ST30SF is that it can operate in passive mode if thermal conditions allow. The unit is equipped with a fan of 80 mm dimensional type; it starts rotating only when the surrounding temperature reaches 55 degrees. This promotes for a considerable power reduction and practically silent work when the fan gets disabled. An average noise level on active operation makes up 18 dB.

SilverStone furnishes the new entry with a single +12V rail, estimated for 22 A current. In its turn, +3.3V rail is estimated for 21 A current, while +5V rail – for 20 A current. It should be noted that this unit …
