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 …

HIS Showcases New Graphics Card with Improved UVD GPU

The line of graphics cards manufactured by HIS has been recently replenished by an alternative Radeon HD 7950 IceQ Boost Clock model. The card takes a modified graphics adapter from AMD and is based on Tahiti PRO chip, developed according to 28 nm technological process. This chip houses 1792 current processors which are designed under an advanced Graphics Core Next architecture.

One of the major technological peculiarities pertained to a new model is the implementation of a unique two-slot IceQ cooler that involves an aluminum heatsink, four copper heat pipes and low-noise powerful fan. As claimed by the manufacturer, the integrated cooling system exceeds the cooler applied in the reference model in terms of heat dissipation power and noise. Hence, noise level produced by IceQ does not exceed the boundary of 28 dB; at the same time, it reduces the GPU temperature at 12 degrees as compared with the reference model.

To continue, Radeon HD 7950 IceQ Boost Clock is based on a …

Evga Unveils More Information about Z77 Mini ITX Motherboard

Last month Evga announced the release of its new motherboard of mini ITX form-factor based on Intel Z77 chip. Currently, there is no information concerning the exact release date, although the company keeps the suspense by providing more data about the future product. The motherboard will be codenamed Evga Z77 Mini ITX and will be compatible with LGA 1155 socket. The board will own unmatched properties to provide for the extreme overclocking facilities.

Evga Z77 Mini ITX is developed on eight-channel power supply subsystem that employs DrMOS IR3550M components. Additional power is supplied by 8-contact EPS12V socket. The motherboard is equipped with Marvell controller that takes responsibility for the operation of eSATA 6 Gb/sec interface on the rear panel. This interface is represented by a couple of eSATA ports. In addition, the rear panel accommodates video slot HDMI, Thunderbolt port, RJ-45 slot (gigabit Ethernet), optical S/PDIF, five Mini-Jack slots (under control of …
