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 to Take Care about Power-Efficiency of Ivy Bridge Processors

The rising competition between the two giants in the manufacture of processing units, Intel and AMD, makes each of the two invent ever newer technologies and implement them in their products. The attempts to dominate in the market and win as many consumers usually develop into brand new approaches and brand new advanced facilities.



In this light, Intel is going to upgrade its Ivy Bridge processors to make them more power-efficient. But power-efficiency does not imply that processing units will show less performance; quite the contrary, the manufacturer is willing to combine an utmost performance with the maximal power efficiency level.


Currently, the most power-saving processors of Ivy Bridge generation can be found in mobile devices on Windows platform and in Apple MacBook Air devices. Their TDP level is recorded at 17W. As appears from the above mentioned, the TDP level in upgraded Ivy Bridge processors will be lower than 17W, though the developers do not voice the margin …
