Chieftec Showcases Five New PSUs from Navitas Series

Chieftec, one of the largest German hardware manufacturers, has recently introduced a new series of power supply units, codenamed Navitas. The series is represented by 5 models: GPM-650C with 650W nominal power, GPM-750C with 750W nominal power, GPM-850C with 850W nominal power, GPM-1000C with 1000W nominal power, and GPM-1250C with 1250W nominal power correspondingly. All the products have won 80Plus Gold certificate, due to more than 90% efficiency in the high workloads.

Chieftec Navitas PSUs correspond to ATX12V v2.3 standard and support Intel Core 4th gen. processors that require little current strength on +12V rail in sleep mode. The models also support active power-factor correction option to provide for the maximal stability during operation. They are equipped with a composite cable system and a single +12V rail, estimated for the maximal current from 54 A to 104 A (this index depends on the unit’s power).

All five units are cooled down by 140 mm fans with PWM …

TUL Takes Up Producing Brand PowerColor Graphics Adapter

TUL Corporation has announced the release of its brand high-performance graphics adapter, codenamed PowerColor Radeon HD 7950 Boost State Edition. The major peculiarity of the new product is the integration of GDDR5 memory type with 384 bit interface and support of multiple advanced technologies.

The model is based on black circuit board with the integrated Tahiti PRO chip, developed under 28 mm technological process. This chip accommodates 1792 current processors designed on Graphics Core Next architecture. This graphics adapter is compatible with PCI Express 3.0 x16 bus and DirectX 11.1 facility. The overall volume capacity of GDDR5 memory equals to 3072 MB. Heat management process is realized due to the two-slot cooling system of active type. The rear panel of the adapter is alloted for HDMI and DVI slots, as well as, for a couple of mini-DisplayPort ports.

The nominal frequency of graphics core equals to 850 MHz; nevertheless, the implementation of AMD PowerTune …

AMD releases new video accelerators and FirePro first APU for workstations

The debut of a new line of graphics cards AMD FirePro Wx000 on base of graphics processors family Southern Islands (28 nm) is also known as the basis for gaming decisions Radeon HD 7000.

Single-chip FirePro W9000 includes a GPU Taxiti XT 4 teraflops of performance when dealing with numbers and a single-precision teraflops in operations with double precision. The volume of on-board video memory is 6 GB of GDDR5, the recommended price — $ 4000. Scope of the discrete graphics FirePro / Southern Islands is traditional: CAD-applications that work with the media content, and system digital signage.

One position lower is FirePro W8000. It uses the kernel Tahiti Pro or XT, characterized by Tflops/806 3.23 Gflops of performance, memory capacity of 4 GB and a price tag of $ 1,600. Even lower in the hierarchy is the FirePro W7000. The card is equipped with 4 GB of GDDR5 RAM and the chip Pitcairn XT (Radeon HD 7870). Performance, according to AMD, is 2.4 Gflops Tflops/152 when …
