It is based on AMD Bonaire GPU with AMD GCN architecture developed under 28 nm technological process. The GPU consists of 896 current processors, 14 computing blocks, 56 texture blocks, and 16 ROP blocks.

Video memory subsystem comprises 1 GB of GDDR5 memory type, employing 128-bit bus. Its nominal clock frequency equals to 1500 MHz, while effective frequency makes up 6000 MHz. The overall efficiency level of this adapter is estimated at 1.79 TFLOPS; this index is twice larger than the one recorded with AMD …

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 …

Thermaltake Enters the Market with NiC L31 and L32 CPU Coolers

Thermaltake Technology has just started shipping a pair of budgetary CPU coolers from NiC series. Entitled NiC L31 and NiC L32, these two models are compatible with all updated Intel and AMD platform motherboards. In keeping with the manufacturer, the new-comers will not obstruct the mounting of memory modules, due to their well-considered framework. Hence, they consist of small-sized heatsinks, three U-shape heatpipes (8 mm), and a base that is in direct contact with the CPU.

The first model, NiC L31 (codename: CL-P001-AL12RE-A), features 140x128x40 mm dimensions and weighs 530 g. The integrated 120 mm fan might operate in various speed modes – from 500 RPM to 1800 RPM – thanks to the support for PWM technology. It produces up to 70.99 CFM and dissipates up to 160 W power.

At the same time, at the minimal speed mode it generates only 18 dB noise, however at the ultimate rotations this index rises to 34.8 dB. According to the results of multiple tests, this fan is …
