Some More Details about Intel Core i7 Haswell Processors

As it was publicized earlier this year, a new generation of Intel Haswell processors will be launched in spring 2013. Along with the line of CPUs for desktop systems, Intel will release a series of mobile CPUs. The release is planned for April 2013. Intel Core i7 Haswell will be a pioneer mobile series and will count only three models: Intel Core i7-4930MX Extreme Edition, Intel Core i7-4900MQ and Core i7-4800MQ. All three models are going to become the best match for laptops of gaming class and portable work stations due to their power consumption.

Intel Core i7-4930MX Extreme Edition is a flagship model in the series. It features four cores and supports Hyper-Threading Technology that enables the operation not with four currents (as the majority of contemporary 4-core CPUs do) but with eight currents. Its nominal clock frequency equals to 3GHz, but thanks to the support of Turbo mode the index might be increased to 3.9GHz with one enabled core and up to 3.7 GHz with all …

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 …

Modular Power Supply 650W Chieftec A80

Evaluating the effectiveness of modern computer power supplies, the most attention is paid to their coefficient of performance (COP) at a given load — usually means of 20%, 50% and 100%. At the same time, not less important requirement, established by standard 80PLUS should be considered. That means — the preservation of this level of performance for all occurring in the world supply voltage variations, that is in the range of 100-240 V.

The standard rules of 80PLUS at different levels (Basic, Bronze, Silver, Gold, Platinum, etc.) are performed for two voltage 115 V and 230 V. In both cases, the normalized PS should show the efficiency of not less than specified for each category level. Not usual power supply CTG-650C model of the new A-80 series from the Chieftec company is interesting in that it has officially claimed efficiency of 85% or more, but only for nets 220-240 V.

As the advantages of such solution can immediately be noted a lower price, due to less stringent …
