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 …

Velox V55 and Slim S55: Two New SSD Series from Silicon Power

Silicon Power, a well-known developer of flash-memory drives, as well as HHD and DRAM, has replenished its inventory with two new SSD series, codenamed Velox V55 and Slim S55. All the models included into the lineups are traditionally designed in 2.5-inch form-factor. Both series will be represented in the market by three models of 60 GB, 120 GB and 240 GB capacity. Their major advantage over rival products lies in acceleration of all operations connected with upload, speed boosting and general performance. Therefore, these SSDs are just perfect for ‘highly-demanding’ users.



Velox V55 solid-state drives are housed in resistant cases made of polished aluminum. All three models feature identical dimensions: 100x70x9 mm and weigh 79 g. The drives are based on SandForce controller and employ SATA III (6 Gb/sec) interface. The maximal sequential speed index claimed by the developer approximates 550 Mb/sec on reading operations and 470 Mb/sec on writing operations. Velox V55 …

The third generation of chips Thunderbolt will be released in the second quarter of the next year

Data interface Thunderbolt from Intel company entered the market in February 2011 in the Apple MacBook Pro laptop. By combining in the one interface PCI Express and DisplayPort, it now offers data rates up to 10 Gbit / s. On the more common personal computers the interface began to be applied recently, as part of the laptop and PC top price category.



Intel plans to introduce a new controller interface Redwood Ridge Thunderbolt for use in personal computers in the second quarter of next year. It is likely that the new controllers will form the platform of the Shark Bay for next generation processors under the name of Haswell.


Controllers Redwood Ridge will support completely the same data rate 10 Gb / s, interface DisplayPort v1.1 and function DisplayPort v1.2 Redriver. At present, even the cheapest chips Thunderbolt, 2-channel Cactus Ridge, cost motherboard manufacturers at about $ 20, and many consumers expect that emergence of new generations of controllers will reduce …
