Exynos is a series of ARM-based System-on-Chips (SoCs) developed and manufactured by Samsung Electronics and is a continuation of Samsung's earlier S3C, S5L and S5P line of SoCs.

History[edit]

In 2010 Samsung launched the S5PC110 (now Exynos 3 Single) in its Samsung Galaxy S mobile phone, which featured a licensed ARM Cortex-A8 CPU.[1]

In early 2011, Samsung first launched the Exynos 4210 SoC in its Samsung Galaxy S II mobile smartphone. The driver code for the Exynos 4210 was made available in the Linux kernel[2] and support was added in version 3.2 in November 2011.[3][4]

On 29 September 2011, Samsung introduced Exynos 4212[5] as a successor to the 4210; it features a higher clock frequency and "50 percent higher 3D graphics performance over the previous processor generation"[citation needed]. Built with a 32 nm High-K Metal Gate (HKMG) low-power process; it promises a "30 percent lower power-level over the previous process generation."[citation needed]

On 30 November 2011, Samsung released information about their upcoming SoC with a dual-core ARM Cortex-A15 CPU, which was initially named "Exynos 5250" and was later renamed to Exynos 5 Dual. This SoC has a memory interface providing 12.8 GB/sec of memory bandwidth, support for USB 3.0 and SATA 3, can decode full 1080p video at 60 fps along with simultaneously displaying WQXGA-resolution (2560x1600) on a mobile display as well as 1080p over HDMI.[6]

On 26 April 2012, Samsung released the Exynos 4 Quad, which powers the Samsung Galaxy S III and Samsung Galaxy Note II.[7] The Exynos 4 Quad SoC uses 20% less power than the SoC in Samsung Galaxy SII. Samsung also changed the name of several SoCs, Exynos 3110 to Exynos 3 Single, Exynos 4210 and 4212 to Exynos 4 Dual 45 nm,[8] and Exynos 4 Dual 32 nm[9] and Exynos 5250 to Exynos 5 Dual.
