Nvidia introduces a new graphics accelerator Tesla K20X intended specifically for supercomputers. Tesla K20X, a flagship model of Tesla K20 series, is based on Nvidia Kepler architecture and is able to secure the highest performance supported by a single CPU. According to the preliminary testing, it ensures ten times faster operation of applications in combination with top-class processors. Moreover, this accelerator is currently supposed to be the most efficient one in the market, providing for utmost speeds and utmost performance ever seen.



Graphics accelerator Tesla K20X is notable by three times lower power consumption if compared with all previous generations of Nvidia products. Besides, it increases the performance discrepancy between GPU and CPU. A bunch of outstanding characteristics ensures 3.95 teraflops in calculations with a single precision and 1.31 teraflops in calculations with a dual precision.


In addition, a new series involves Tesla K20 accelerator that …

Like Intel, AMD Company is not protected to the release of a large number of faulty processors, which are eliminated at the stage of laboratory tests. Some have a non-working cache (or part thereof), other — x86-cores, and others — a graphics block, and a fourth — a weak memory controller. According to this, there are releases of less productive CPU, but working with a moderate price tag. About unlocking cores / cache in AMD processors users probably know firsthand.



As the saturation of the defective inventory APU Trinity platform FM2, AMD will decide on the mass production of new models of AMD Athlon II X4. They will be easily distinguished from its predecessors on the number of the form 7xx.


Integrated Graphics Radeon VLIW4, of course, will be disabled. Frequency will be slightly reduced for marketing purposes. Overclocker devotees will primarily be interested in quad-core Athlon II X4 750K of free factor. The operating frequency of the model — 3.4 GHz, cache …

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 …
