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 …

Palit Announces an Overclocked GTX 760 JetStream Graphics Card

Palit has replenished its line of gaming graphics adapters with a new model, codenamed Palit GeForce GTX 760 JetStream. It is differentiated by an original design of the PCB, a highly-efficient JetStream cooling system, and a factory overclocking. Outstanding overclocking potential is secured by the implementation of high-quality components, such as DrMOS MOSFET transistors.



The new-comer employs PCI Express 3.0 x16 interface and is based on GK104 GPU (28 nm Kepler microarchitecture). The core consists of 1152 stream processors, 32 ROPs and 96 TMUs. It runs at an overclocked frequency of 1072 MHz, but on activating GPU Boost technology, this index rises to 1137 MHz high. Such showings exceed the reference parameters at about 10%.


To continue, this graphics card is equipped with 2 GB of GDDR5 memory type that runs also at heightened frequencies. Hence, the nominal clock frequency makes up 1550 MHz, while GPU Boost increases this index to 6200 MHz. Memory subsystem employs …

Kimdecent created a computer Droid Stick T4 for lovers of small devices

Personal computer — this has long been not only a cumbersome system unit and monitor, as this phrase is now called nettops and more compact devices of class «micro-PC.» For public discussion was presented the computer Droid Stick T4 from a Chinese company Kimdecent, barely surpassing dimensions of a standard USB-stick with its size.



Initially, the micro-PC Kimdecent Droid Stick T4 comes with preinstalled Google Android, updated to version 4.0.4 Ice Cream Sandwich, but the manufacturer provides the ability to install any other distro. The only requirement is to it — the support of processors with the architecture of ARM. By the way, a modification of Linux Ubuntu can work with it.


The system in this case is on the internal flash memory of 4 GB, which can be increased through the use of cards microSD. Supported capacity — 32 gigabytes. Kimdecent Droid Stick T4 is based on the processor Allwinner A10 dual-core and 1.5 GHz. Full-time package includes a 1-gigabyte memory …
