Two new PC chassis, codenamed Matr-X A and Matr-X M, have replenished the line of products supplied by PNL-tech GmbH. The company delivered its chassis under Rasurbo brand and directed the models to the average price segment. Both models are developed in midi-tower form factor and are housed in steel casings painted black; they feature identical 485x197x493 mm dimensions but differ from each other by the side panel framework. Matr-X A contains a large transparent window on the side panel, while Matr-X M has got a blind panel.



Chassis Matr-X A and Matr-X M are fully compatible with micro-ATX and ATX motherboards. Their dimensions and facilities allow for the installation of seven expansion slots, six internal 3.5-/2.5-inch drives, and four external 5.25-inch drives. Functional section consists of a special dock-station for the connection of an additional drive; this dock-station is located on the top panel. Next to it, one can find a set of USB interfaces, counting a couple of …

The Internet community is actively discussing new Intel's development, processors Poulson, that belongs to the tenth generation of Intel Itanium. All previous data about the upcoming product were vague and void of official proofs. Currently, the data are more ample and allow the community to study the future processor in more details. Thus, Intel Itanium 9500, codenamed Poulson, will be presented by four models the release of which is planned for early autumn.



The crystal of Poulson processor will consist of 3.1 billion transistors that are called to form eight computing cores. Each core counts up 89 million transistors and the pipeline width is doubled to twelve instructions. This way CPU developers implement more efficient approach towards transistor budget. Just for comparison purposes, Poulson's predecessor, Tukwila, counted 109 billion transistors per core.


To continue, Poulson CPUs will accommodate a couple of cache memory arrays, five channels of QPI bus, system …

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 …
