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 …

DAS CFI-B8253JDGG Review

The majority of people are probably familiar with NAS-servers, their destination and facilities. DAS-drive is a completely unique device, targeted specifically at business owners and home enthusiasts. This is a multi-functional device developed for the connection directly to the host-systems which can be represented by home PC, router with USB interface, server or some other gadget. CFI Group, primarily known by PSU development and supply, has introduced an innovative storage solution in the form of its DAS CFI-B8253JDGG model. This product is called to rival NAS competitors in price range which is quite moderate if compared with the general market prices. The major destination of DAS is office employment, however it can be used for home purposes as well.

Preview of Intel Itanium 9500 Specifications

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 …
