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.

ViewSonic reports about the release of a new series of affordable monitors – the VX57. The lineup entails a 22.-inch VX2257-mhd, a 24-inch VX2457-mhd and a 27-inch VX2757-mhd item. Each of the models is based on Full HD TN panel (1920x1080) with 170/160 viewing angles and superfast response time – 1.2 ms. Static/dynamic contrast index makes up 1000:1/80M:1. Therefore, the new-comers are appropriate for entertainment purposes (gaming, multimedia).



The integrated panel ensures the maximal brightness of 250-300 cd/m2, 24-84 kHz & 47-75 kHz of horizontal/vertical refresh rate. The displays are furnished with a pair of 2-watt speakers as well as a set of video interfaces: a pair of audio ports, 1x HDMI, 1x DisplayPort and 1x D-Sub. The backside of the panel houses 100x100 VESA bracket for wall mounting.


Besides, the triple comes equipped with a number of integrated technologies:

— Game Mode with pre-installed profiles (FPS1, FPS 2, MOBA, RTS) and three customizable …

The stonewall in the tablet and mobile CPU segment is gradually mounting, with Intel and Nvidia increasing their influence and rivalry. Hence, Intel's developers claim that its latest tablet processor, two-core Atom Clover Trail, surpasses Nvidia's Tegra 3 in both performance and power consumption. To be precise, Clover Trail proves to be more efficient in a range of applications, but at the same time, it consumes power twice less than its counterpart. To exemplify such claims, Intel takes Imagination Technologies graphics that consumes less power than Tegra 3.



Numerous testing results conducted by Intel and some leading IT analysts demonstrate that Tegra 3 with four main cores and one additional core is slower that Clover Trail. Testing of performance and power consumption has been held on Microsoft Surface RT with Tegra 3 chip and Windows 8 tablet with Clover Trail chip. Nevertheless, Intel hasn't conducted any comparison in mobile OS from Google.
