They Did It! Official Release of AMD Radeon HD 7990 ‘Malta’

Much rumored reference graphics adapter from AMD has been recently officially introduced. As it was suggested before, Radeon HD 7990, codenamed ‘Malta’, employs two Tahiti XT2 GPUs, each of which contains 128 TMUs, 32 rasterization blocks (ROPs), and 2048 current processors (GCN architecture). Smooth work of both graphics cores is synchronized by means of PLX PEX8747 controller that supports 48 lines of PCI Express 3.0. Nominal clock frequencies ascribed to GPUs operation equal to 950 MHz, but Turbo mode enables the increase of frequencies up to 1000 MHz.

Video memory is represented by GDDR5 memory modules, the overall capacity of which equals to 6 GB (3 GB per each graphics core). Memory modules utilize 384-bit bus and run at 6000 MHz frequency with bandwidth of 288 Gb/sec per core. The incorporated PCB accommodates a single CrossFireX socket for the creation of various graphics configurations, including Quad-CrossFireX. Video interface panel boasts the availability of …

HIS Adds a Couple of Middle-Yielding Graphics Cards to Its Inventory

The inventory of HIS production line has been refilled with a couple of new graphics cards that belong to middle-yielding solutions. The couple enters HIS 7770 IceQ X Blue series and is targeting those users who would like to enjoy all the privileges of gaming process for a sensible price. Codenamed HIS 7770 IceQ X Blue and 7770 Ice Q X Blue Turbo, these entries are able to provide for an outstanding viewing effect, while playing the most up-dated games.

The heart of both graphics adapters is AMD Cape Verde TX core with 640 current processors, developed under 28 nm Graphics Core Next architecture. Model HIS 7770 IceQ X Blue runs at reference clock frequency of 1000 MHz, while its Turbo colleague is factory-overclocked and runs at 1100 MHz frequency. In respect to video memory, this couple accommodates 128-bit GDDR5 modules. Their nominal clock frequencies make up 1125 MHz and 1200 MHz (for Turbo model), while their effective frequency index achieves 4500 MHz and 4800 MHz …

Meeting New Cooling System Brocken 2 from Alpenfoehn

Only a couple of weeks are left till the official release of a new cooling system Brocken 2 designed by Alpenfoehn. This is a long-awaited launch, since the fist version of the system, entitled Brocken, was honored to gladden the audience long time ago. Hereby, Brocken 2 has got a wee bit modified framework, if compared with the predecessor. Its dimensions together with a fan equal to 146x100x165 mm.

The base is shaped by means of five 6 mm copper heat pipes, tightly pressed together. Aluminum plates of the heatsink seem to be ‘cut’ in the center, unlike the one-piece construction of plates implemented in Brocken.

Active cooling power is ensured by a nine-blade fan of 140 mm standard size, known as WingBoost 2. The fan supports PWM technology that allows altering its rotational speed within the boundaries of 400-1100 RPM. Its activity stimulates the airflow index of 109 CFM, while the noise level barely achieves 19.6 dB (A). WingBoost 2 features small distance between …
