Exynos, the line of System on a Chip (SoC) products from Samsung, were notably absent of ARM Mali GPUs. This, apparently, struck concern over how viable Mali will continue to be and whether ARM will continue to lose designs to competitors such as Imagination Technologies.
Then Samsung announced, Monday evening for us North Americans, the upcoming Exynos 5 Octa Processor will embed six ARM Mali-T628 GPU cores. The T628 GPU cores are capable of OpenCL 1.1 and OpenGL ES 3.0 standards which should allow applications to offload heavy batches of tasks, such as computational photography processing, with high efficiency and performance.
The Exynos 5 Octa contains four ARM Cortex-A15 cores at 1.8GHz, supported by four additional Cortex-A7 cores clocked at 1.3GHz. These processors are currently being sampled and should be produced in August.

Samsung talked up a new ARM SoC during CES that will become the new high-end part of its Exynos 5 lineup. The Samsung Exynos 5 Octa is, as the name suggests, an eight core processor. It is built on a 28nm manufacturing process and employs ARM's big.LITTLE architecture.
While Samsung is not ready to share all the detailed under-the-hood details, the Exynos 5 Octa has four Cortex A15 cores clocked at 1.8GHz paired with four Cortex A7 cores clocked at 1.2GHz. With big.LITTLE, the SoC has both high performance, high powr cores and lower power cores. The configuration is invisible to the end user, and the chip will use the Cortex A15 cores when in 3D applications or other CPU load intensive applications. Then, while the phone is idle or simply running background applications (notifications, checking email, updating twitter and facebook feeds, ect), the SoC will power down the Cortex A15 cores and use the lower power-drawing A7 cores. Ideally, this will give users a "best of both worlds" situation and a balance of performance and battery life.
Samsung claims that the Exynos 5 Octa offers up to twice the 3D performance of other existing current-generation SoCs. However, we do not yet have details on the GPU improvements (if any) over Samsung's other Exynos 5 chips much less benchmark-able products running this chip yet so it is difficult to say whether that statement is true or not. Also, Samsung claims as much as a 70% improvement in power savings over its dual core Exynos 5 processor, which is certainly a bold claim.
According to Engadget, Samsung plans to reveal all the nitty-gritty details on the eight-core Exynos 5 Octa SoC at the International Solid State Circuits Conference on February 19, 2013. It should give NVIDIA's "4+1" core Tegra 4 a run for its money, at lest on the CPU front (and maybe 3D graphics as well, but it's hard to say at this point).

While details are still sparse as we await the official start of Mobile World Congress in Barcelona tonight/tomorrow, it appears that Samsung plans to announce a new quad-core processor as part of its Exynos line. It will be the first Samsung SoC based on 32nm technology rather than the 45nm currently in production and will be available in both quad- and dual-core variant.
According to the story over at Unwiredview it will be available in frequencies ranging from 200 MHz all the way up to 1.5 GHz while offering lower power consumption than current options. I am curious how this actually stacks up though as we have seen that Tegra 3 doesn't REALLY offer lower power consumption and longer battery life even though that was a promise from NVIDIA. It definitely can offer less power consumption per performance unit, but in the end battery life is king for these mobile devices.
What about graphics performance? The story had this to say:
The new Exynos comes paired with the latest version of Samsung’s own graphics chip, which has 4 pixel processors and 1 geometry engine with 128 KB L2 cache. The graphics support OpenGL ES 2.0 and can generate up to 57 MPolygons/s.
Samsung claims that the new processor will offer 26% more performance compared to Exynos parts based on the 45nm process and I assume they are referring to dual-core vs dual-core results. Other claims include battery life improvements of "up to 50%" - we'd love to see it but we'll wait for actual devices to ship and showcase it before really getting excited.
The good news is that quad-core performance will be coming to more devices and NVIDIA won't be the only SoC designer on the block offering them. The use-cases for quad-core performance on a mobile device, phone or tablet, may still be in question though we never doubt the software side of the equation to utilize as much horsepower as it is provided.
