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 …

Company XFX is preparing Radeon HD 7970 GE with Double Dissipation cooler

American vendor XFX is about two weeks to release a Radeon 7970 Edition Double Dissipation (model code — FX-797G-TDF). It combines the capabilities of GPU Tahiti XT2 with a higher overclocking potential and the TDP, rather than at Tahiti XT, PCB reference design, but without a single phase power supply (6 +1), and the cooling system in the vaporizing chamber, an array of aluminum fins, PA plate (the same heatsink for the VRM and memory), as well as the two fans standard size 90 mm.



New model will get the recommended for the Radeon HD 7970 GE frequency ratio 1000/6000 MHz for core and chips GDDR5. The graphics chip will operate at 1050 MHz in the load. Recall that the “usual” HD 7970 was limited to regular frequencies 925/5500 MHz and did not support dynamic overclocking.


The configuration of video outputs is almost standard: from the five of DVI-I, DVI-D, HDMI and 2x Mini DisplayPort for some reason excluded DVI-D. The additional power is supplied by one 8-pin and one …

Welcome a Novelty from Acer – a 38” XR382CQK Monitor

Once again Acer decided to impress customers and launched an advanced 38-inch monitor under the XR382CQK codename. The Taiwan company has produced a specialty with a refined curved IPS-panel featuring a 2.3 m curvature radius, 10 bits of colour precision and the 100% coverage of the sRGB colour gamut.



The resolution of Acer XR382CQK is 3,440 х 1,600 pixels. This product offers the 5 msec response time, the 75 Hz refresh rate, the 300 cd/m² brightness, as well as 172° and 178° view angles (horizontally and vertically respectively).


On the backside of the device one can find a DisplayPort, an HDMI, a four-port USB 3.0 hub and a Type-C USB 3.0 connector. The 7 W stereospeakers and the AMD FreeSync technology support should also be highlighted.


The XR382CQK display by Acer is already available to official retailers at the estimated cost of $1,300.
