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 …

Evga Debuts with a First-Rate ACX CPU Cooler

Evga, a company primarily known for high-end graphics solutions, decided to expand its production line by entering cooling market. Herein, it elaborated a first-rate CPU cooler, entitled ACX (codename: 100-FS-C201-KR). The new-comer features 164x134.5x91.5 mm dimensions and weighs 1065 g. Luckily, it can be already found in free sale for a price of $50.

The ACX is a tower-like air cooler that is able to efficiently remove heat from all processors that are compatible with the following sockets: Intel LGA 2011/1156/1155/1366/1150/775 and AMD FM1/FM2/AM3/AM3+/AM2/AM2+.

Evga ACX consists of an aluminum heatsink, five copper heatpipes that support Direct Touch technology, and one PWM fan of 120 mm dimensional type. The heatsink is composed of multiple thin plates, which differentiate themselves by an unusual framework. Such framework enables the emergence of two airflows around the heatpipes. According to Evga, this promotes for a better heat removal process.

Sapphire Vid-2X Display Expander Review

Display expanders cannot be found in abundance on PC hardware market. In fact, not every user knows what the main purpose of those devices is. In the most general meaning, display expanders are splitters that allow the connection of two monitors towards a single output on a graphics card. However, their destination is not limited by this function only, since it might serve some other means as well. Sapphire introduces its own similar solution in the form of Vid-2X Display Expander model. The manufacturer assures that this splitter differs from traditional couplers in terms of functional and reliability.


Splitter Sapphire Vid-2X Display Expander is housed in a black plastic casing with gray side plates. The casing's cover is divided in two parts; the spacing between them serves ventilation and heat management means. The base accommodates rubber stands which provide for the framework steadiness. It should be mentioned that Sapphire delivers two models simultaneously …
