Lifting the Veil from USB Type-C Bus

Since the launch in 1995, Universal Serial Bus (USB) has proved itself as the most successful ever computing interface. Nowadays tens of billions of electronic devices are connected together due to it. It goes without saying that this bus has outlived a few modifications, each distinguished by higher speed and reliability. Thus, today the community is able to revel in a completely new modification – USB Type-C – that forecasts a lot privileges of connectivity process. Let’s see what users will get with a new bus.



Layout and Connectivity


In physical terms, Type-C is a bit larger than USB 2.0 Micro-B but a bit tinier than binary USB 3.0 Micro-B, featuring 8.34x2.56 mm. Such dimensions enable its connection to the devices of any type, including the thinnest smartphones/tablets. The oval-shaped socket houses 24 contact outputs (to compare: USB 3.0 sockets feature only 9 outputs).


The most outstanding physical peculiarity of Type-C is a symmetric connector that …

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 …

Deepcool Launches the Follower of Big Frost Cooler

Deepcool, a Chinese supplier of various cooling systems, is going to release a follower of Big Frost model that saw the light last July. The new product has been given an attribute 'Extreme Edition' and is currently codenamed Big Frost Extreme Edition. This cooler takes the basis of the predecessor, though still features some unique options.



Therefore, Big Frost Extreme Edition is distinguished by a nickel coverage of copper heat pipes and polished base surface that is in direct touch with CPU lid. Deepcool equips its cooler with two 120 mm fans (UF120) which are monitored by PWM controller. Their maximal rotational speed is estimated at 1500 r/m. Both fans ensure the utmost CPU cooling and proper airflow distribution.


According to the preliminary data claimed by the manufacturer, Big Frost Extreme Edition will be compatible with such desktop platforms as AMD FM1, FM2, AM2/AM2+, AM3/AM3+ and Intel LGA2011, LGA1366, LGA115x.
