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).


To continue, GeForce GTX 770 …

Scythe SCIOR-1000: a Comprehensive CPU Cooler with Top-Flow Design

Scythe is going to start the sales of its newest CPU cooler, entitled SCIOR-1000. It is honored for a comprehensive nature, since it might work with all contemporary CPUs, except for Intel Socket LGA2011 models. The other remarkable thing ascribed to the product is the employment of Top-Flow design.



Therein, the fan is localized over the heatsink, directing the airflow towards the whole framework, including the nickel-plated base. This way, it promotes for a better cooling effect.


Scythe SCIOR-1000 embraces also three 6 mm heat-pipes, along with a 100 mm fan. The latter supports PWM technology, so is able to reach the speed of 1800 RPM. The maximal noise level achieves 26.7 dB. Release date is scheduled for the final days of 2013. Some other specifications about the cooler are described below:

— framework dimensions: 136x117x107 mm, weight – 400 g.;

— supported platforms: Intel – LGA1366/115x/775 and AMD – FM1/FM2/AM2/AM2+/AM3/AM3+;

— heat-pipes: …

An All-new Series of Super Flower Power Supply Units Is Introduced by 10 Devices of 400–850 W Capacity

The Super Flower Co. is widely known by virtue of its 80Plus Titanium power modules. At present this manufacturer is going to present a cutting-edge series of low-profile devices.



The latest line will include ten power supplies, the capacity of which varies in the range of 400–850 W depending on the model. Those of them providing 750 W and more will get partially detachable cables.


Being optimized by Super Flower professionals, the topological layout of these Super Flower products is based on the two-transistor forward converter. PWM and PFC schemes are designed with a Fairchild controller and Infineon field-effect transistors. Hardware components also incorporate STMicroelectronics and Mospec diodes, a Fujitsu relay and a Teapo electrolytic capacitor.


All models of this series are intended for Super Flower OEM customers and comply with 80Plus Bronze standards.
