Sapphire Showcases Radeon HD 7870 GHz Edition Toxic Solution

Sapphire Technology Ltd. is going to release a new graphics card on Tahiti LE chip. Codenamed Radeon HD 7870 GHz Edition Toxic, the card is one of the first models to use the newest GPU, developed under 28 nm technological process. The suffix 'GHz Edition' in the model's name witnesses that the nominal GPU clock frequency exceeds the index of 1 GHz.



The core of Sapphire Radeon HD 7870 GHz Edition Toxic is based on Graphics Core Next architecture and contains 1536 current processors. The card's inventory involves 2GB of GDDR5 memory with 256-bit bus interface. The memory modules are known to operate at 6000 MHz frequency. GPU operational frequencies are still not clarified, but it's possible to assume that on activation of AMD PowerTune option the card will demonstrate some outstanding performance. In fact, analysts dare saying that this model is the most efficient one among all other solutions based on Tahiti LE chip.


Optimal thermal regime and airflow activity are …

Asus Launches a Wide Range of Nvidia Maxwell-Based Adapters

Asus is the one to introduce the largest assortment of graphics adapters based on a fresh Nvidia Maxwell GPU. The range of suggested products involves two models from Asus GeForce GTX 750 series and three models from Asus GeForce GTX 750 Ti series. All five new-comers are differentiated by an ameliorated PCB design with the incorporation of Super Alloy Power components.



The GTX 750 series consists of GTX750-PH-1GD5 and GTX750-PHOC-1GD5 cards. Both of them come with an integrated Nvidia GM107-300 GPU, equipped with 512 CUDA cores. The first model operates at 1020 MHz/1085 MHz (nominal/boost) frequency, whereas its companion runs at 1059 MHz/1137 MHz. They employ 1 GB of GDDR5 memory, demonstrating 1252 MHz/5010 MHz (nominal/efficient) frequency. The cards also have an identical video interface panel that embraces one HDMI, one D-Sub, and one DVI-D port.


The GTX 750 adapters accommodate analogous cooling system with a single Dust-Proof Fan. The latter is called to keep the …

Company LEPA produces new power supplies B-series

LEPA introduced three new power supplies — B650-SA, B700-MAS and the B800-MAS, which will replace older models B750-MA, and B850-MA. Newcomers have been certified with 80 Plus Bronze (efficiency of 88% of the networks 230V), and met the standards of ATX12V v2.3 and EPS12V 2.92, and positioned as solutions for gamers and owners of GPU configurations SLI and CrossFire, workstations and small servers.



New items are equipped with inverter DC-DC (to improve stability), have the topology of Double Forward Circuit, as well as high-quality electrical components: solid capacitors and heat resistant (105 ° C) capacitors made in Japan.


Active cooling LEPA B700-MAS/B800-MAS is provided by 140-mm fan on double bearings. The model B650-SA has a fan size of 120 mm. The intensity depends on the rates of temperature sensor. Power Cables PCI-E, SATA and Molex flat are detachable. The main ATX 24-pin, as well as “CPU” EPS12V 8-pin are collected in a nylon sheath. LEPA B650-SA has …
