Samsung 8-core CPU Will Arrive in 2013
Samsung 8-core CPU Will Arrive in 2013
Samsung is reportedly preparing to release an 8-core processor next year, sometime in February. The chip will be displayed at the International Solid State Circuits conference in San Francisco, which runs February 17-21. The currently unnamed chip will be constructed with a 28nm size, and is a combination of both A15 and A7 cores.
Four A15 cores will run at 1.8GHz, while four A7 cores will be clocked at 1.2GHz. Each set of cores is designed for different uses-the faster cores for power and performance, the slower ones for efficiency and battery savings. Even the lesser A7 quad-core set is claimed to be equal in performance to today’s iPhone4s, and the Galaxy Nexus. The A15 cores are said to have up to 5 times the performance of the average smartphone in use today.
The architecture is described by ARM as “big.LITTLE”, and runs one set of quad-cores at a time, never all eight simultaneously. It is possible that this chip will debut in a tablet, possibly the follow-up to the Nexus 10.

Because you only split things out so far for parallelism, and that includes loaded tasks against actual ram.
If you want an active 8-core where everything gets used, you need a lot more ram than today, or apps written to exploit more parallelism. Probably both.
And unlike cores, sections of ram can't go to sleep, so that's going to be a power draw just for real estate.
BIGlittle has already been out and proven itself to a certain point, this is its next evolution. It's designed as an either-or deal to go fast or go efficient, on the fly.
The Tegra 3 quad core does this with a single little core (it's the quad with 5 cpus). Think of this like that, only the BIG gets a big boost going from the A9 to A15 architecture and the little gets a boost from one to quad to ease the transition from a single little core to multiple BIG cores.
Is this the best way? Is this a good way? Will it come through on promises? Will others just go on the big V-8 kinda engine? How much power in real life? How hot?
Your guess is as good as mine, I think we'll have to just see them.
But on paper, does it make sense? Yes, I think so.
Samsung Exynos 5 Octa eight-core processor makes its CES 2013 debut
Quote:
Hot on the heels of the announcement of the Samsung Galaxy Note 10.1 for Verizon and the availability details for the ATIV Odyssey, Samsung today made another mobile announcement that ought to get even more mobile fans excited. The company just officially introduced the Exynos 5 Octa processor, an eight-core chip that Samsung promises will be a low power, high performance piece of silicon.
Using the ARM big.LITTLE system, the Exynos 5 Octa uses two pairs of four cores each to divvy up the workloads, with the Cortex-A7 being used for basic tasks and the Cortex-A15 cores meant for more powerful work. Samsung says that this allows the Exynos 5 Octa to offer high performance as well as 70 percent higher energy efficiency when compared to the previous quad-core Exynos processor. The Exynos 5 Octa is also said to feature 3D gaming performance that's twice what is available with any other mobile processor around.
The Exynos 5 Octa is designed for use in high-end smartphones and tablets, but so far there's no word on when we might start to see these devices pop up. With today's news and the recent announcement of Qualcomm's Snapdragon 600 and 800 series processors, though, it definitely looks like mobile spec hounds have quite a bit to look forward to. Now we just have to wait for products equipped with these new chips to start appearing on shelves so that we can really see how they perform.
