Company XFX is preparing Radeon HD 7970 GE with Double Dissipation cooler

American vendor XFX is about two weeks to release a Radeon 7970 Edition Double Dissipation (model code — FX-797G-TDF). It combines the capabilities of GPU Tahiti XT2 with a higher overclocking potential and the TDP, rather than at Tahiti XT, PCB reference design, but without a single phase power supply (6 +1), and the cooling system in the vaporizing chamber, an array of aluminum fins, PA plate (the same heatsink for the VRM and memory), as well as the two fans standard size 90 mm.



New model will get the recommended for the Radeon HD 7970 GE frequency ratio 1000/6000 MHz for core and chips GDDR5. The graphics chip will operate at 1050 MHz in the load. Recall that the “usual” HD 7970 was limited to regular frequencies 925/5500 MHz and did not support dynamic overclocking.


The configuration of video outputs is almost standard: from the five of DVI-I, DVI-D, HDMI and 2x Mini DisplayPort for some reason excluded DVI-D. The additional power is supplied by one 8-pin and one …

Zalman ZM-GVM Introduces ZM-GVM Bronze PSUs

Zalman adds another series of power supply units to its portfolio. The ZM-GVM series is represented so far by three semi-modular units of 500 W, 600 W and 700 W capacity. They correspond to ATX12V 2.31 standard and boast 80Plus Bronze certificate since their efficiency achieves 88%. The new-comers are able to operate in a wide range of input voltages (115-230 V), featuring only a single +12V rail.



Zalman ZM-GVM units employ dual forward converter as the basis. Semi-modular design presupposes permanent fixture of the main cables and demountable construction of optional cables. Efficient cooling is the task for a low-noise 120-mm fan, whereas sustainability of the units is entrusted to the advanced protection system.


Zalman ZM500-GVM PSU accommodates 1x 24-pin connector, 4+4-in ATX 12V, 3x MOLEX, 5x SATA, 1x FDD, and 2x 6+2-pin PCI Express connectors. The ZM600-GVM offers 4x MOLEX and 6x SATA connectors in addition to the base ones. The senior ZM700-GVM houses 4x MOLEX …

Sapphire Continues Its Victorious Onset on Graphics Card Market

News about fresh releases from Sapphire gladdens all potential customers and IT specialists with enviable frequency. The most recent news touches upon the upcoming release of a fresh graphics card codenamed HD 7870 XT with Boost. This model is based on AMD Radeon HD 7870 adapter and employs Tahiti chip with 1280 current processors and 80 texture blocks. The chip is designed on Graphics Core Next architecture that secures its improved facilities. The model employs PCI Express 3.0 x16 interface.



The integrated GPU works at nominal 925MHz frequency, but on activation of PowerTune Boost option this index rises to 975MHz. Memory, that is represented by 2GB of GDDR5 memory standard, demonstrates 6000MHz frequency. It provides for 192-bit rail access. An inventory of video interfaces involves a couple of mini-DisplayPort outputs, a single Dual Link DVI-I and a single HDMI port. Moreover, this graphics card supports AMD Eyefinity technology that allows the connection of several …
