Arctic Releases Cooling System for AMD Graphic Adapters

Swiss manufacturer of cooling systems, Arctic Cooling, has recently released a new cooler developed specifically for graphic adapters from AMD. Earlier this year the company launched the cooling system which is compatible with graphic adapters from Nvidia developers. The new product, codenamed Accelero Hybrid 7970, distinguishes from its predecessor also by the foot of water block which is upgraded to be compatible with AMD HD 7900 series.

Cooling system Accelero Hybrid 7970 consists of two parts which boast as air, so water cooling standards. It is able to manage up to 320W of hot air. The water block is cooled down by the 120 mm fan which is able to achieve the speed in the measures of 400-1350 rpm. The block, that is installed on the board, is equipped with 80 mm fan and is able to achieve from 900 to 2000 rpm speed. The noise level is dwindled down to the minimal index.

Arctic representatives claim that their new water block is 200% more efficient than the nominal …

Asus to Release Entry-Level Radeon R7 250 Graphics Card

Asus has added a new entry-level graphics card based on Radeon R7 250 adapter to its inventory. Codenamed R7250-OC-2GD3, it is predestined to be employed in corporate and multimedia systems, which are bound to support graphics interface of various applications, play back video, edit photos, and to start unexacting games. The model features a bright design and some remarkable facilities that promise to make work and entertainment experience a delight.

Asus Radeon R7 250 is based on 28 nm GCN chip (AMD Radeon R7 250) that contains 384 stream processors. It runs at the nominal 1060 MHz frequency but can be overclocked to 1110 MHz; that makes 60 MHz more if compared with the etalon adapter. Memory subsystem is introduced by 2 GB of DDR3 memory chips with 128-bit rail. Their nominal clock frequency starts at 900 MHz with the possibility to reach 1800 MHz effective margin.

This graphics card employs a modified PCB that comes with Super Alloy Power hardware base. All the included …

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 …
