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 …

Zalman ZM-GVM Introduces ZM-GVM Bronze PSUs

Zalman adds another series of power supply units to its portfolio. The ZM-GVM series is represented so far by three semi-modular units of 500 W, 600 W and 700 W capacity. They correspond to ATX12V 2.31 standard and boast 80Plus Bronze certificate since their efficiency achieves 88%. The new-comers are able to operate in a wide range of input voltages (115-230 V), featuring only a single +12V rail.



Zalman ZM-GVM units employ dual forward converter as the basis. Semi-modular design presupposes permanent fixture of the main cables and demountable construction of optional cables. Efficient cooling is the task for a low-noise 120-mm fan, whereas sustainability of the units is entrusted to the advanced protection system.


Zalman ZM500-GVM PSU accommodates 1x 24-pin connector, 4+4-in ATX 12V, 3x MOLEX, 5x SATA, 1x FDD, and 2x 6+2-pin PCI Express connectors. The ZM600-GVM offers 4x MOLEX and 6x SATA connectors in addition to the base ones. The senior ZM700-GVM houses 4x MOLEX …

Gigabyte is preparing an overclocked version of GeForce GTX 660 Ti

Despite the measures taken by Nvidia partners to maintain the confidentiality (up to 16th of August ) of marketing sketches and precise characteristics of the line graphics cards GeForce GTX 660 Ti, it is still becomes the property of IT-society long before the official announcement. The resources tell about a new video card Gigabyte GeForce GTX 660 Ti, equipped with a cooler WindForce 2X.



New product will be released in two versions — with increased and recommended frequencies. Graphics adapters will have the same appearance, but the cost will vary depending on the characteristics. Video card without overclocking is functioning at 915 (980) / 6008 MHz, OC-option has clock speeds of 980 (1032) / 6008 MHz for core and 2 GB of memory GDDR5, respectively. In the arsenal of adapters there are as well video outputs DVI-I, DVI-D, HDMI (gold plated) and DisplayPort, two slots SLI and graphics chip GK104-300-KD-A2 (1344 shader, 112 TMU, 24 ROP, 192-bit memory bus).
