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 …

CPU Cooler Phanteks PH-TC12PE Review

Phanteks is the company that established reputation for developing and supplying high-end thermal solutions which can be applied in diverse areas. Recently the company has made a shift to the IT market by producing high-quality PC cooling systems and at once entered into competition with the renowned cooling systems manufacturers, like Thermalright, Noctua and others. Phanteks PH-TC12PE cooler belongs to the echelon of high-end air cooling solutions and proposes a number of benefits for the advanced PC users.



Design and Integration


Cooler Phanteks PH-TC12PE is a two-sectional thermal solution that goes in 160x140x132 mm dimensions (without fans). Edges of pipes are cut and covered by a plate. The top surface of the ribs is glossy, while the bottom surface is dull. The implemented approach to the design of fans' framework and their fixture, that allows the user to fix the fans at different height, makes the installation of this cooler even in midi-tower chassis possible. …

Haswell processors for laptops will consume up to 57 W, desktop - up to 100

Intel provides with three graphics levels: GT1, GT2 and GT3. Desktop processors won’t receive graphics performance higher than GT2, but mobile processors will be able to boast of with GT3 class. Support of PCI Express 3.0 for Haswell processors will be quite usual characteristics, but at the memory controller little progress is seen — yet provides dual-channel DDR3-1600.



By energy consumption Haswell desktop versions will be divided into models with values of 35, 45, 65 and 95 watts of TDP level. For mobile processors the values are ​​37, 47 and 57 W. Finally, ultra book processors with built-in system logic will be filled by TDP level not more than 15 watts. It is assumed that this will enable them, among other things, be in standby mode up to 10 days without charge.


The desire of Intel to compete with AMD in terms of performance integrated in graphics processor, will add some work to companies producing cooling systems for laptops. The developers report about …
