Samsung working on quad-core ARM Cortex-A15 chip with 4 extra low power cores
Samsung plans to introduce a new processor for phones, tablets and other mobile devices in February. Some folks are calling the new chip an 8-core processor, and that’s actually kind of true. But really, it will offer the performance of a high-end quad-core ARM-based processor and the power savings of a low-power quad-core ARM chip.
Big.LITTLE is ARM’s chip design that lets you pair a low power companion core with a high performance chip. When a phone or tablet is idle or performing basic tasks, it can shut down the high power core to save power and rely on the companion core.
Right now, Samsung’s highest performance ARM-based chip is the Samsung Exynos 5250 dual-core ARM Cortex-A15 processor. That’s the chip found in the $249 Samsung Chromebook and $399 Google Nexus 10 tablet.
According to EE Times, Samsung will unveil its new quad-core variant in at a conference in February.
The chip will be based on a 28nm design. The Cortex-A15 cores will run at speeds as high as 1.8 GHz and feature 2 MB of L2 cache. The Cortex-A7 cores will go up to 1.2 GHz.
While Samsung is introducing the new processor in February, we probably won’t see it in actual products until later in the year. Samsung introduced the Exynos 5250 almost a full year before that chip actually started shipping.
