Earlier this week, Samsung announced that it was bringing Heterogeneous Multi-Processing (HMP) to Exynos 5 Octa chips. Samsung didn't clarify if HMP would require new hardware, but that was the implication. Now Meizu has unexpectedly announced the Exynos 5 Octa chip in its recently unveiled MX3 will be getting HMP through a software update.
All Exynos 5 Octa processors until now have used cluster migration to manage the ARM big.LITTLE cores.
Since Samsung announced the Exynos 5 Octa at CES 2013, one major criticism has been leveled at its implementation of big.Little technology time and again: for some reason, it has only ever been able to run 4 of its 8 cores at a time. Not only that, but it has never been able to mix-and-match the higher performance A15 cores with power efficient A7 cores to get the best possible configuration for performance and power usage.
We don't see a lot of Exynos chips shipping in Samsung phones in the US, but the rest of the world is swimming in devices running Samsung's in-house ARM chip. The Exynos 5 Octa (5410) debuted in the Galaxy S4, and now an updated version of that chip known internally as the Exynos 5420 has been officially announced.
Like the older Exynos 5 Octa chip, the 5420 has eight total cores that leverage ARM's big.LITTLE design.
Do you like octa-core processors? How about displays that curve? Or just Samsung in general? If you answered "yes" to any of those questions, then you're going to want to watch Samsung's second CES event, which just so happens to be available now on YouTube.
For the Exynos 5 Octa stuff, jump straight to 12:34. If you're more into the flexible OLED, they show the prototype off at 39:48.
