Intel Xeon Phi Architecture

Intel has a vast portfolio of technology its engineers have developed, and Xeon Phi unquestionably taps some of that. However, the Many Integrated Core architecture is notably more than a bunch of modified Pentium processors manufactured at 22 nm. Some of its notable attributes include:

• An in-order, dual-issue x86 design with 64-bit support
• Four threads per core, and up to 61 cores per coprocessor
• 512-bit SIMD for wider vectors
• 512 KB of L2 cache per core (up to 30.5 MB per Xeon Phi)
• 22 nm tri-gate transistors
• Red Hat Enterprise Linux 6.x or SuSE Linux 12+ support
• 6 or 8 GB of GDDR5 per card

ARM launches 64bit architecture

ARM unveiled two 64-bit processor design today, the Cortex A57 and A53. A57 will boost the performance of three of the top smartphones today. Meanwhile A53 presents the same performance as that used on the Cortex A9 Nvidia Tegra 3 chipset but with only the size of a quarter.

According to ARM, the new processor design not only increases the speed of smartphones and tablets, but also will reduce the electrical power consumption.
