Xbox One

The Xbox One is a home video game console developed by Microsoft. Announced on May 21, 2013, it is the successor to the Xbox 360 and the third console in the Xbox family. It directly competes with Sony Computer Entertainment's PlayStation 4 and Nintendo's Wii U as part of the eighth generation of video game consoles.

Xbox One is powered by an AMD "Jaguar" Accelerated Processing Unit (APU) with two quad-core modules totaling eight x86-64 cores clocked at 1.75 GHz, and 8 GB of DDR3 RAM with a memory bandwidth of 68.3 GB/s. The memory subsystem also features an additional 32 MB of "embedded static" RAM, or ESRAM, with a memory bandwidth of 109 GB/s. Eurogamer were told prior to its release that, for simultaneous read and write operations, the ESRAM is capable of a theoretical memory bandwidth of 192 GB/s and that a memory bandwidth of 133 GB/s has been achieved with operations that involved alpha transparency blending.The system includes a non-replaceable hard drive[47] and a Blu-ray Disc optical drive. 138 GB of hard drive space is used by the operating system, with the remainder available for the storage of games. Since the June 2014 software update, up to two USB drives can be connected to Xbox One to expand its capacity. External drives must support USB 3.0 and have a capacity of at least 256 GB. Xbox One supports Gigabit Ethernet, 802.11n wireless, and Wi-Fi Direct, 4K resolution (3840×2160) (2160p) video output and 7.1 surround sound.
