Nvidia Debuts with GeForce GTX 770 Graphics Adapter

Trailed by the flagship GeForce GTX 780 model, Nvidia officially launches one more high-performance graphics adapter of 700 series, codenamed GeForce GTX 770. Albeit the two products are rather similar in design (i.e. the incorporation of identical two-slot cooling system), their layout differs considerably. First of all, GTX 770 employs less efficient graphics core Nvidia GK104-425-A2 (28 nm) with 1536 CUDA cores, 128 TMUs, and 32 ROPs. At the same time this GPU operates at higher frequencies: 1046 MHz (nominal), 1085 MHz (dynamic).

Nvidia’s new entry comes either with 2 GB or 4 GB video memory modules of GDDR5 type. They employ 256-bit interface and ensure high bandwidth of 224 Gb/sec. Memory operational frequency is truly striking, demonstrating up to 1752 MHz (nominal) and up to 7010 MHz (dynamic) index. It should be noted that models with 4 GB modules will cost $50 more than those with 2 GB items (the recommended price makes up $399).

Cooler Master Showcases G-Series PSUs

Along with the launch of new PC chassis, Cooler Master is ready to release new G-series power supply units. The series is introduced by three models – G500, G600 and G700 – with 500W, 600W and 700W power, respectively. All of them correspond to ATX12V v2.3 standard, support Active PFC option and a range of protection tools (from short circuit, overvoltage, current overload, power overload). Moreover, these units employ a dual EMI-filter and take benefit from a single 120 mm fan with automatic speed control functions.

Cooler Master G-series PSUs have been felicitated with 80Plus Bronze certificate, due to their high efficiency (approximately 85%) and an estimated mean time between failures of 100.000 hours. The two junior models, G500 and G600, are able to operate at 456W and 576W load, correspondingly, on +12V rail. They are quipped with six SATA Power sockets and a pair of PCI Express Power 6+2-pin sockets. G500 unit will come to the market at the price of €60, while …

Motherboard Gigabyte Z77MX-D3H TH Review

Each new year brings new ideas for the developers of PC hardware. Since motherboards are indisputably the main component in the PC integration, their design and facilities are given the most attention. Hence, each manufacturer tries to implement some unprecedented technologies to attract potential audience by an improved performance and possibilities. Intel Thunderbolt technology is a hit of 2012; that is why, motherboard designers turned their looks into this direction. Gigabyte was among the first companies to integrate Thunderbolt interface into its products: model Z77MX-D3H TH is a bright evidence of it.


Motherboard Gigabyte Z77MX-D3H TH resembles the modification of its predecessor Z77MX-D3H, except for the availability of Thunderbolt interface and design of PCB. The renunciation of the third PCIe x16 slot allowed the manufacturer to free four lines of PCIe bus and employ Thunderbolt technology for their activation. As a result, a new product has got a …
