New characteristics of co-processors Xeon Phi

For several years, developed Intel Larrabee graphics cards have changed its destiny, and now proudly referred to coprocessors Xeon Phi. The June announcement gave a very rough idea of ​​their characteristics and applications (highly specialized servers and workstations). Now some details will be revealed.



Bboosters Xeon Phi will be available in versions with 57, 60 and 61 core. There are in general 64 computational units, but some of them will be disabled. Depending on the number of cores the cache size varies from 1.8-1.9 MB first level and 28-30,5 MB second. The volume of onboard GDDR5 memory is 3, 6, and 8 GB.


Intel Xeon Phi device will operate on a low clock rate from 600-1100 MHz for the lower 57-core models with 3 and 6 GB of GDDR5, to the 630-1050 MHz or more for the older 60 — and 61-core board with 8 GB of RAM. Effective memory frequency will be in the range of 5-5.5 GHz. Support for dynamic overclocking Turbo Boost will be provided by reasonable balance of …

Intel is preparing a new motherboard on chipset Z77 and Z75

Intel Corporation has a rather wide range of motherboards for processors Core i5/i7-3000 (Ivy Bridge), but, nevertheless, continues to produce products based on chipsets 7-Series. According to reports, the release of two motherboards Intel LGA1155 — DZ77GAL-70K is planned soon with code-named Gasper Light and DZ75ML-45K (Middle Lake). The first model uses a set of system logic Z77, second — Z75. Both models will receive a certificate of Windows 8 WHQL, support of Fast Boot technology and Lucid Virtu MVP.



Model Intel DZ77GAL-70K is based on the same PCB, as the previous DZ77GA-70K (Gasper) and DZ77RE-75K (Roads End). In contrast to the board DZ77GA-70K, new doesn’t have a rich set of delivery: WiDi-compatible adapter with an antenna, Bluetooth, remote panel with two USB 3.0 ports and a mouse pad Intel Extreme Series. Due to this, it will be cheaper than DZ77GA-70K.


In turn, Intel DZ75ML-45K (Middle Lake) is a compromise models between the DZ77SL-50K and DH77KC. This …

OCZ Announces the Release of Agility4

OCZ company representatives have proudly announced the release of their new SSD child of Agility 4 series. Agility4 series embraces four models which correspond to the 64 GB, 128 GB, 256 GB, and 512 GB volume capacity parameters. Agility4 developers claim that their new series is the balance of performance, speed and reliability at the same time.



The new series is based on Indilinx Everest 2 controller and is equipped with SATA III interface. SSD Agility4 is built on flash-memory chips of MLC NAND type which are destined to sustain up to 2 million hours of fail-proof operability. These chips support TRIM and SMART technologies and are sure to involve ECC option to monitor and remove all detected errors. The other peculiar feature of Agility4 SSDs is the availability of DRAM cache-memory of 1 GB volume capacity. In addition, SSDs have an integrated option of automatic encoding according to AES algorithm.


It should be mentioned that each individual model in a series proves …
