Report: Samsung to snub Cortex-A72 for custom ‘Mongoose’ processor


Exynos chip

Samsung might opt to use its own custom-built processor cores in one of its upcoming mobile chips.

The company has already ditched Qualcomm’s chips for its in-house Exynos system-on-a-chip series, but a new report suggests Samsung might take this new lease of independence one step further.

A post on Chinese site Baidu (via GSMArena) claims the Korean tech giant is working on a processor codenamed ‘Mongoose’, although the source for the information isn’t revealed.

The processor will allegedly rely on the company’s highly efficient 14nm FinFET manufacturing process, and will make use of ARM’s ARMv8 chip design.

The maximum clock speed for the processor core is tipped at 2.3GHz, with a Geekbench score for the processor cited as 2,200 for single-core testing.

That puts the new processor at around 40 per cent more powerful than Samsung’s current flagship Exynos 7420, a chip that appears in the new Galaxy S6 and S6 Edge smartphones.

As the source isn’t cited, it’s difficult to say whether these latest rumours are even remotely true.

It wouldn’t exactly be surprising if Samsung was working on a high-end mobile processor however, as the company is already known to be keen to wean itself off other companies.

While many of this year’s flagship smartphones will use Qualcomm’s Snapdragon 810, for example, Samsung has loaded its own top-end devices with custom-built chips.

ARM’s new Cortex-A72 processor design is also expected to make an appearance in premium 2015 handsets. A Samsung-built processor, however, would mean the South Korean company wouldn’t need to rely on ARM’s designs for its own SoCs.

Do you think we’ll see a custom Samsung processor on the Galaxy Note 5? Let us know in the comments.

"...and will make use of ARM’s ARMv8 chip design."
"...would mean the South Korean company wouldn’t need to rely on ARM’s designs..."
I'm confused.

the difference between licensing a prefabricated design, and licensing the right to the architecture from which you can create your own designs.


the old Samsung cores tend to be ArmV7 (arch), while using the A15 (design).
the old Snapdragon cores tend to be ArmV7 (arch), while using their own custom (design).

in theory, if you have the cash and expertise you can create a faster or more efficient (design) if you wish, in which case you merely license the (arch), if you don't have those resources you take a shortcut and license both the (arch) and a prefabbed (design).

SFIK you only need an expensive arch license oi you plan to design your own cores, like Apple. Most ARM partners just license the core designs, This is working out fine for Rockchip and Mediatek. You save time as well as money just going with the ready-made design. ARM aren't incompetent.
