According to a recent report by the famous newspaper Korea Times, Samsung is working on a new eight-core processor with architecture big.LITTLE that would use for its next flagship, the Galaxy S4.
The prestigious journal has recently published a report on the business prospects of Samsung and Hynix SK, the two leading semiconductor manufacturers in South Korea, which reads as follows:
The world’s largest electronics maker by revenue plans to unveil a new AP based on ARM’s big.LITTLE processing that will realize an octo-core processor to be used in the Galaxy SIV
Surprising eh! For those unfamiliar with processor architectures and new trends in this field will comment briefly on what the new architecture big.LITTLE is about.
big.LITTLE is one of the great innovations in the field of processing for next year that addresses one of the main challenges in the industry: how to create a SoC that provides high performance and at the same time, extreme energy efficiency to prolong battery. big.LITTLE connects the performance of ARM Cortex-A15 or Cortex-A57 with energy efficiency of the Cortex-A7 or Cortex-A53, allowing an application to move between them according to requirements without problems. The architecture big.LITTLE selects optimal processor for each task, thereby extending battery life by up to 70%.
This means that big.LITTLE is a computing architecture heterogeneous than couples slower processors and low power, with more powerful processors to create a multi-core processor that can be adjusted to the needs of each task and provide a high yield when necessary, thereby improving power consumption.
ARM revealed a while ago that the first devices to offer their new architecture big.LITTLE would come to market in 2013 but without giving too much detail.
In theory, these processors can have several different configurations (two powerful cores and four cores efficient for example), but most likely the first generation chips big.LITTLE will have symmetrical configurations (2 +2 or 4 +4).
According to a publication of EE Times, Samsung will present the first CPU big.LITTLE at a conference in February 2013. The report says the chip will feature an eight-core configuration composed of four Cortex A15 chips at 1.8GHz with 2MB L2 cache and four cores Cortex A7 at 1.2 GHz, both based on 28nm technology.
Samsung Galaxy S4 with 8-core processor?
So will we see a Samsung Galaxy S4 of eight cores? When semiconductor manufacturers reveal new technologies, it usually takes a few months before the first products based on these technologies reach the shops. For example, Samsung unveiled its Exynos 5 Quad in a technical paper in August but the first devices to run that chip (Exynos 5250) were the Samsung Chromebook and Google Nexus 10, both released in November.
If these processors are presented in February, this would give time for Samsung to work on its implementation in the Galaxy S4, which is expected by mid-next year. However, we must also take into account other factors, the GPU. The Exynos 5 Quad are associated with Mali T604 GPU with a Cortex-A15 CPU quad-core, so if Samsung launches the Galaxy S4 with new big.LITTLE, the GPU would have to adjust to it. Will Samsung be inclined to play it safe and go with a tried and tested design in Galaxy S4 or risk and attempt to innovate with big.LITTLE chips?
Some analysts argue that it is more likely that the first device to integrate an eight-core processor is a tablet, like the the Galaxy Note 10.1 2 or Galaxy Note 3 which will have a 6.3-inch screen and it would be launched in late 2013.
However, we can not rule out the possibility of seeing an eight-core chip in the Galaxy S4 since Samsung was restructured and divided into two recently, so the company is not the same as last year. The Galaxy S3 has been very successful around the world, so the pressure so that the Galaxy S4 is equally or even more successful still, is much bigger.
Furthermore, it is expected that the Galaxy S4 incorporates a large screen 1080p HD Super AMOLED 4.99 inches with a resolution of 1,920 x 1,080 pixels and a ppi of 441, 2 GB of RAM, 64 GB of internal memory and 13-megapixel camera.
Will we see a Galaxy S4 with big.LITTLE eight cores processor? It is still early to confirm anything, but it’s a possibility. At least Samsung has the technology and capacity to do so, but may not want to risk carrying a technology so new and untested in finished products to its flagship, probably the most anticipated device of 2013.
What do you think? What will Samsung do? Would you like to see a Galaxy S4 with an 8-core processor? Leave me your thoughts in the comments!
