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 …

Processors Intel Haswell to Rival Accelerator NVIDIA Tesla

Intel Corporation has the intentions to introduce DDR4 memory into their server processors of Haswell series. The launch of such technological approach is planned for the 2014, however the developments in this sphere have already started. Intel’s server solutions will become a part of Grantley platform and the samples of their new series will allegedly be announced next autumn. The preview of new processors makes it clear that some of the chips will be distinguished by the increased heat generation performance which will reach 160 W.

Hence, 16-core processors Haswell-EP will rival parallel computing accelerator NVIDIA Tesla but not AMD server solutions. Intel is going to provide various working frequency options and options with different number of active cores. At the same time, TDP will fluctuate within ranges of 160, 145, 135, and 120 W. In its turn, accelerator NVIDIA Tesla, which is based on GK110 processor, consumes approximately 300 W.
