Samsung Exynos 5 Dual core processor

World’s First Cortex-A15 Dual core

Exynos 5 Dual is designed for high-end tablets that require multi-window operations, full multitasking, and fast response while running applications.
Exynos 5 Dual is the first chip in the market to integrate Cortex-A15 dual core.
The computing capability of Cortex-A15 dual core is similar to the CPU of a personal computer.
The DMIPS/MHz of Cortex-A15 is 40% higher than the older generation Cortex-A9 core.
The 32nm process of Exynos 5 Dual can increase the Cortex-A15 speed up to 1.7GHz, while the older 45nm process Cortex-A9-based Exynos 4 Dual runs at 1.4GHz. 1.7GHz Cortex-A15 dual core is 2 times better performance than 1.4GHz Cortex-A9 dual core.
Cortex-A15 CPU core, with enhanced VFP and Neon coprocessor, is 1.5 times faster in integer performance and 2.0 times faster in floating-point performance than Cortex-A9 core.
In interconnection, it also supports 128-bit AMBA4 master and slave ports with upcoming cache coherent interconnect.

World’s Best Mali-T604 GPU with 3D Performance

Currently, the 3D graphics engine in mobile operating systems is used for 3D rendering and for all basic graphic work on the screen.
Because the 3D graphic engine operates UI overlay, homescreen, 3D games, and more, 3D performance has become a very important feature for measuring Mobile AP's overall performance.
The 3D performance in the Exynos series has always been beyond compare, however, Exynos 5 Dual will raise the bar for mobile AP’s 3D performance even higher.

Screen resolution is directly related to 3D performance.
WQXGA resolution is four times better than WXGA, meaning that mobile APs must deliver 3D performance at least two times better than the previous generation.
To meet the standard of WQXGA resolution, mobile AP requires a new 3D engine and architecture.
Samsung System LSI worked closely with ARM to achieve the quad core Mali-T604, the most advanced mobile 3D engine to 6 WHITE PAPER date.
With Mali-T604, Exynos 5 Dual delivers two times better GPU performance than Exynos 4.
Since Exynos 4 has more than enough 3D performance to satisfy WXGA resolution, Exynos 5 Dual is the only mobile AP that can handle WQXGA content with 60fps updates.
In addition, the 3D feature of Exynos 5 Dual fully supports GPGPU, including openCL v1.1 full profile.
GPGPU is a solution that distributes the CPU's computation workload to the GPU. In GPGPU support, the floating point performance and precision of GPUs are the key factors.

While CPUs can handle 64-bit floating point (double-precision), most mobile GPUs can only handle 32-bit floating point (single-precision).
Exynos 5 Dual is the first mobile AP that can run double precision floating point and full precision with outstanding 72GFlops floating point performance.
With this functionality, a developer can handle more precise and heavy computation works by simultaneously using Exynos 5 Dual’s cortex-A15 dual cores and quad Mali-T604 cores performance.

World’s first 12.8 Gbytes/sec Memory Bandwidth with 2-port 800MHz DDR3L

In a worst case scenario, memory bandwidth can be very critical. 60 frames per second is the speed after which the after-image effect is no longer visible.
The UI frame rate has been developed up to 60 frames per second, enabling users to experience a smooth transitioning motion. 60fps on WQXGA easily breaks the conventional requirement of memory bandwidth. Displaying a 24bpp WQXGA screen at 60 frames per second consumes 1GB/s bandwidth.
Because it is combined with partial images and UI icons, the final display out requires 8GB/s bandwidth. This is effective bandwidth that does not include memory utilization. If utilization is 80%, required real bandwidth becomes 10GB/s.
Furthermore, WQXGA display combined with worst case scenarios (such as UI with overlay types of 1080p video playback, camera preview, and encoding, and simultaneous HDMI out to HDTV) makes memory bandwidth management more difficult.
Exynos 5 Dual has been designed for WQXGA display, with effective bandwidth, therefore, it can support such worst case scenarios.
Exynos 5 Dual has adopted the mobile industry’s first 2-port 800MHz DDR3 to support 12.8GB/s, which is two times wider than the bandwidth of Exynos 4 Dual. With 12.8GB/s memory bandwidth, Exynos 5 Dual 5 can make seamless UI motions and rich application operating momentum on a WQXGA resolution.

Ultimate WQXGA Display Solution with Low-Power eDP

Normally, the conventional MIPI interface has a maximum of 4 lanes, ideally running at 1Gbps.
However, in most cases, when considering EMI and tuning issues, effective speed is less than 900Mbps. Therefore, using MIPI interface cannot guarantee more complex resolution higher than Full HD.
This is the first case in which a mobile AP has integrated eDP. Exynos 5 Dual does not require an external eDP converter to support WQXGA. Furthermore, conventional eDP is used for laptops and consumes much more power than the MIPI interface used in mobile devices.
Thus, Samsung System LSI has specially designed eDP for Exynos 5 Dual, with power consumption at six times less than a conventional eDP interface.

1080p 60fps Video Performance and VP8 Decoder

After Exynos 4 Dual 45nm, support for full HD 30fps became the main functionality in high-end mobile APs.
Also, the video decoding feature of Exynos 4 Dual 45nm enabled end users to play most existing video codecs without any additional encoding. Exynos is the best solution for playing and recording video; however, the demand for better quality video and Stereoscopic 3D content requires a more advanced video engine.
Exynos 5 Dual is first in the market to support full HD 60fps video encoding/decoding. It can display stereoscopic contents through integrated HDMI v1.4a, moreover, Exynos 5 Dual H/W video codec can decode VP8 codec for Web-M and Web-P to full HD 60fps.
With full HD 60fps encoding, the user can record video in full HD 60fps, and also transfer and display a full HD video on TV via WiFi display. When a user wants to watch a full HD video through WiFi display, the mobile AP must first decode the content and then re-encode and packetize later. For this activity, the mobile AP needs to simultaneously process at least 30fps decoding and encoding.
WiFi display requires a lot of memory bandwidth because not only does 1080p video need to be decoded and encoded at the same time, but also because basic UI and communication need to work. Thus, Exynos 5 Dual is the core of the perfect home entertainment solution and is the only option to make real WiFi display with more options for application scenarios.

USB 3.0 DRD Solution for Faster PC Sync UP and LTE

The size of WQXGA content, advanced 3D games, and 1080p 60fps video data is approximately three times larger than content made for previous generation mobile devices.
To support this amount of data, Exynos 5 Dual provides USB 3.0 with 5Gbps SuperSpeed mode, which is 10 times faster than USB 2.0. Moreover, Exynos 5 Dual's USB 3.0 is a Dual-Role Device, meaning it can detect the status of a slave device by its connector's signal and then operate as either Host or Device. With DRD mode, Exynos 5 Dual supports keyboard, external storage as USB Host, PC sync as USB device, and LTE data modem.


Exynos 5 Dual provides multi-windows and multi-tasking with exceptional 3D performance. Its 32nm HKMG process, low-power eDP combine to provide overall lower power consumption.
Add in its 12.8GB/s memory bandwidth and its DDR3L 800MHz RAM, and users will experience seamless UI & graphics for even longer.
Thanks to the world's first Cortex-A15 dual core and all the features it brings with it, Exynos 5 Dual is the complete solution for future WQXGA resolution devices.
