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 …

Welcome In New LPDDR4 Memory Chips from Samsung

Samsung settles down to a large-scale production of LPDDR4 mobile memory chips. Elaborated according to 20 nm technological norms, the new-comers boast the integration of an advanced technology that ensures 8 Gb crystal density and twice the performance compared with LPDDR3 chips. Currently, the company produces models of 2 GB and 3 GB capacity, however in early 2015 it will set to the development of 4 GB solutions.

New LPDDR4 memory modules are targeting various mobile devices with thirst for lightning-fast data transfer speed. The latter index might accelerate up to 3200 Mb/sec; this will allow employing chips for the implementation of resource-intensive tasks, such as recording and playback of high-resolution video or serial filming.

Samsung developers claim that 2 GB LPDDR4 DRAM is 40% more power-efficient than counterparts with 4 Gb crystal density. This became possible due to the adopting of low-voltage swing-terminated logic for I/O signaling. As a result, the …
