Exynos 5250: More Smarter, More Greener!
Almost a year has passed since we told about the representative of “green and smart” ARM processors: Exynos 4210 , which became the crown of the flagship Samsung GALAXY S II . And now, there is another reason for discussion and expectations: Samsung Semiconductors launches the Exynos 5250 straight from the tin in mass production.
The new architecture, designed to replace the Cortex-A9 CPU core in the market, was announced by ARM two years ago. These processors today are equipped with most smartphones and tablets. The new Cortex-A15 (codename - Project Eagle: James Bond - neither give nor take) will allow you to take the next frequency line, supporting the device at an impressive 2.5 GHz. This will allow ARM to reach a new level of performance competition in a wide range of devices, even in servers.
It's no secret that new mobile devices appear on the market literally every week, but processor architectures are updated only once every 2-3 years. The upcoming ARM Cortex-A15 is all the more interesting. Many companies are hard at work on solutions based on this chip, but Samsung already has something to show.

Since the Samsung Exynos 5250 was announced last year, I haven’t read about it unless I'm lazy. The company manufactures a new processor based on metal gate technology and high-k dielectrics (High-K Metal Gate), using its own 32-nm low-power process technology. The processor consists of two Cortex-A15 cores with a frequency up to 2 GHz and a 4-core accelerator of the new generation ARM Mali-T604. The transition to the 32-nm process technology, coupled with the new energy-saving technologies, made it possible to reduce the power consumption of the Exynos 5250 by 40-50% compared to chips that were previously created using the 45-nm technology.
In the picture below, you can see how much the power consumption of the 2-core Exynos 4212 processors, made on the 32-nm process against the predecessor of the Exynos 4210, using the 45-nm manufacturing technology, is reduced.
The Exynos 5250 with the new ARM chip can handle 14 billion instructions per second (DMIPS) at 2 GHz. This figure is twice the capabilities of the 2-core Cortex-A9 at a frequency of 1.4 GHz. The memory bandwidth was also doubled: to 12.8 GB / s - thanks to the 2-channel 32-bit memory controller, LPDDR2 / DDR3, with a frequency of 800 MHz.
As for the graphics 4-core accelerator ARM Mali-T604, it is difficult to assess or objectively compare with something, because no mobile device has yet carried something similar on board. According to Samsung, the Exynos 5250 will be 4 times faster than the Mali-400 used in the GALAXY S II graphics. Among the key accelerators supported by the API are: OpenVG 1.1, OpenGL ES 2.0, DirectX 11 and OpenCL 1.1.
The Exynos 5250 supports resolutions up to WQXGA (2560x1600), which corresponds to the capabilities of the “company-which-we-do-not-call” display, produced, by the way, also by Samsung. One energy saving solution is based on the eDP interface (embeded Display Port). eDP is compatible with Panel Self Refresh (PSR) technology, which tells the processor not to display data on the LCD panel in the event that a static picture is displayed.
The 4-line MIPI connection allows support for high-resolution sensors: 8-megapixel images are processed at up to 30 frames per second, thanks to an ISP processor.
It is worth mentioning the built-in support for high-speed interfaces USB 3.0, SATA3, UART, as well as HSIC and C2C, interacting with LTE modules. The eMMC 4.5 standard is also supported, which provides an internal MMC speed of up to 200 MB / s.
Undoubtedly, the Exynos 5250 is designed to replace Qualcomm solutions in all future Samsung devices. It should be a strong competitor to the Qualcomm S4 processor, built on its own Krait architecture.
