Zotac GeForce 640 GT: Kepler for $ 100

The emergence of a new GPU architecture does not only make records in the performance of high-end graphics cards, but often changes the idea of what to expect from an inexpensive card with a low TDP. Let see what can offer GT 640 — associate member of the family Kepler



The lower segment of the GeForce 600 is already fully staffed. In retail, there are cards GT 610, GT 620, GT 630 and GT 640, and in the OEM- channels additionally supplied GeForce 605. But among all of them, only GT 640 can be called a fully new model, since it is based on the architecture of Kepler, and the remaining cards are a familiar model series GeForce 400 and GeForce 500 Architecture (Fermi) with certain minor modifications.


GeForce 640 is based on the GK107 chip, which previously debuted in accelerators GeForce 640M. The performance of the last was comprehensively studied on the laptop Acer Aspire M3-581TG: compared to the GeForce 540M new chip provides a very nice speed boost. GK107 contains one …

Greeting a Pair of Liquid Freezer 120 & 240 Coolers

Arctic announces a pair of liquid cooling systems entitled Liquid Freezer 120 and Liquid Freezer 240. They are targeting the most demanding CPUs designed by Intel & AMD. The first model perfectly matches processors with up to 250 W TDP, while the second one might cope with 300 W TDP. Pricing is set at 100 EUR and 130 EUR correspondingly. Both new-comers are shipped with a brand Arctic MX-4 thermal compound.



Arctic Liquid Freezer 120 accommodates a waterblock with a copper base, an efficient pump, 120-mm heatsink, long connecting hoses (326 mm), and a couple of 120-mm fans, based on a fluid dynamic bearing. They are monitored by means of PWM technology, enabling them to rates within 500-1350 RPM speed range. At the same time, the maximal noise level does not exceed 0.3 Sone.


To continue, Arctic Liquid Freezer 240 is distinguished by the implementation of a 240-mm heatsink and four 120-mm fans. Tests prove, that this cooler is able to maintain the temperature of Intel Core …

Intel Claims Its Clover Trail More Efficient than Tegra 3

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.
