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 …

LEPA introduced three new power supplies — B650-SA, B700-MAS and the B800-MAS, which will replace older models B750-MA, and B850-MA. Newcomers have been certified with 80 Plus Bronze (efficiency of 88% of the networks 230V), and met the standards of ATX12V v2.3 and EPS12V 2.92, and positioned as solutions for gamers and owners of GPU configurations SLI and CrossFire, workstations and small servers.



New items are equipped with inverter DC-DC (to improve stability), have the topology of Double Forward Circuit, as well as high-quality electrical components: solid capacitors and heat resistant (105 ° C) capacitors made in Japan.


Active cooling LEPA B700-MAS/B800-MAS is provided by 140-mm fan on double bearings. The model B650-SA has a fan size of 120 mm. The intensity depends on the rates of temperature sensor. Power Cables PCI-E, SATA and Molex flat are detachable. The main ATX 24-pin, as well as “CPU” EPS12V 8-pin are collected in a nylon sheath. LEPA B650-SA has …

Computer mouse truly belongs to the line of universal and integral peripheral devices in the computer layout. This is not an exaggeration as practically any PC activity involves the work of a mouse. With the progress of computer layout and emergence of laptops and netbooks, traditional mouse has outlived major transformations and enabled the work with those gadgets by means of wireless connection. The popularity of portative mouse pieces grows each and every day due to their compact size and handiness in usage. Developers of Microsoft Arc Touch put the design, handiness in usage and technical peculiarities of a mouse in the limelight, allowing the targeted customer groups to admire their product.
