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.

Announcement of video card Gigabyte Radeon HD 7970 Super Overclock

The efforts of Gigabyte engineers culminated in the release of the Radeon HD 7970 Super Overclock, also known as GV-R797SO-3GD. This is a monstrous construction with height of 64 mm (3.5 expansion slots) and a cooling system WindForce 5X. As well as preparing to be released GeForce GTX 680 SOC, the new adapter uses a five high-speed (> 4000 rev / min) fan size of 40 mm, copper evaporation chamber, and five copper heat pipes.



WindForce 5X – is one of the most expensive VGA-coolers, except for models with water blocks and liquid cooling system. It will allow to overclock Gigabyte GV-R797SO-3GD up to frequencies of 1155/7620 MHz. However, neither the temperature nor the noise performance of video card can be considered satisfactory: 85 degrees under load and 91 ° C for overclocking with increased voltage, and 8000 rpm in a heavy-duty (1185 MHz, 1.375 V) explains the situation.

A 2-Fan Cooler GeForce GTX 1050 WINDFORCE 2G Graphics Card From GIGABYTE

The GIGABYTE company has officially introduced a new graphics card, named GIGABYTE GeForce GTX 1050 WINDFORCE 2G (GV-N1050WF2-2GD). It possesses such peculiarities as refined PC-board design and a modified cooling system.



GIGABYTE GeForce GTX 1050 WINDFORCE 2G is based on a 14 nm NVIDIA GP107-300 GPU, supporting 640 CUDA, 40 TMU and 32 ROP. This video card can operate in one of pre-set modes – “Gaming” or “OC”. Its frequency formula goes in accord with the benchmark of 1354 / 1455 MHz in the first case and 1379 / 1493 MHz in the second. At the same time 2 GB of GDDR5 memory work at the reference effective frequency of 7008 MHz.


The PC-board is improved due to the Ultra Durable VGA company concept and an enhanced 4+1-phase power subsystem construction with one 6-pin PCIe connector. The power supply subsystem design features one copper composite heat pipe, an aluminum heat sink, a stiffening plate on the reverse side and a pair of axial fans. At low load the cooler …
