AMD Officially Introduces Radeon HD 7790 Graphics Card

An official introduction of a new graphics card from AMD, entitled Radeon HD 7790, has been settled into a dedicated press briefing. Within the framework of this briefing, the company not only gave a detailed description of a long-awaited product but also divulged a comparative performance analysis with its main rival’s adapter – Nvidia GeForce GTX 650 Ti. Therefore, AMD Radeon HD 7790 graphics card belongs to mainstream items and is targeting a wide range of customers. 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 …

LEPA to Release MX-F1 and MaxGold 1000 PSUs

LEPA is ready to release a new series of entry-level power supply units entitled MX-F1. The series counts three models of 400 W, 500 W and 600 W capacity: N400-SA-EU, N500-SA-EU and N600-SA. In addition, the company has expanded its MaxGold line with a flagship 1000-watt model. It corresponds to Intel ATX12V 2.4 standard and employs an optimized hardware design.

To begin with, MX-F1 PSUs offer 87% of ultimate efficiency. Operating at 20%/50%/100% loading, they are able to achieve 82%/85%/82% efficiency correspondingly. Nonetheless, the models cannot receive 80Plus Bronze certificate, since they feature limited voltage input range. All the models within the series employ a single +12V rail and boast a non-modular design.

This promotes for the connection of middle-efficiency components. They support Active PFC and a wide spectrum of protective functions (over-voltage, over-current, over-power, short-circuit). Cooling of internal components is ensured by a single 120 mm fan. …

ECS Debuts with a New GTX660TIA-2GR5-WFM Graphics Card

ECS, a well-known designer of graphics solutions, announces the release of its new graphics card GeForce GTX 660 Ti, also known as GTX660TIA-2GR5-WFM. The card is elaborated on the basis of a reference adapter from Nvidia. GPU GK104 (designed according to 28 nm technological process) is the heart of the model. It consists of 1344 CUDA cores and features 915 MHz nominal frequency that can be dynamically overclocked to 980 MHz.

Memory subsystem of ECS GeForce GTX 660 Ti embraces 2 GB of GDDR5 memory that runs at the nominal 1502 MHz frequency but can be increased to the effective 6008 MHz mark. The manufacturer decided not to alter recommended by Nvidia parameters in their own version. The connection with GPU resources is realized via 192-bit rail.

This graphics card employs PCI-e 3.0 x16 internal interface. A set of external video interfaces totally corresponds to the etalon requirements and involves one DisplayPort, one HDMI, and a pair of DVI ports.
