We’re back again for the final phase of our second Build-a-Rig competition. For this round we are doing a theme relevant to many a younger enthusiast: back to school computers. In this Round we invited both Tony Ou from SilverStone and Jeremy Mo…
In an unexpected and surprise annoucement, Samsung today revealed its new generation flagship SoC – the Exynos 8. The Exynos 8890 to be more specific, is the successor to the Exynos 7420 that we’ve come to know very well in this year’s Galaxy flagships such as the Galaxy S6 or the Note5.
The Exynos 8890 is still an 4+4 big.LITTLE design using four Cortex A53 cores in the little cluster, but on the big cluster we see for the first time Samsung’s own custom developed CPU architecture deployed in silicon. The new core, officially called the Exynos M1, is the first fruit of years-long efforts by Samsung’s Austin R&D Center to try to create an in-house CPU architecture. What we do know of the M1 is that it’s still very similar to ARM’s big core architectures (And thus might be a derivative) such as the A72: It’s still a 3-wide OoO design with the same amount of execution pipelines and similar, although not quite identical pipeline stages on the execution units.
Samsung follows MediaTek’s example by dropping the use of ARM’s CCI IP in favour of designing their own cache-coherent interconnect fabric aptly named SCI (Samsung Coherent Interconnect). It seems that vendors are keen to try to improve their SoC architectures by designing fully optimized SoC fabric solutions and I guess Samsung saw the need to differentiate in this regard.
On the GPU side, we see usage of an ARM Mali T880MP12. This is the biggest Mali core implementation to date and increases the number of cores by 50% compared to the Exynos 7420’s MP8 configuration. Keeping in mind that the T880 also increases ALU pipelines per core by 50%, we’re looking at a 2.25x increase in computational power assuming Samsung kept the clock frequencies equal. Alternatively, they could go lower in frequency for much improved power efficiency. Samsung advertises 4K as an option for this SoC so likely we’re looking at a very powerful GPU setup.
Lastly, but not least, is the announcement that the Exynos 8890 is part of Samsung’s ModAP lineup, meaning this is a part with a modem. The new modem supports LTE Category 12 download speeds with up to 3x carrier aggregation up to 600Mbps or uploads speeds up to 150Mbps on Cat. 13 with CA. This effectively makes the new Shannon modem on the 8890 equal Qualcomm’s Snapdragon 820 modem capabilities. Until further future confirmation on the matter, I fail to use the “integrated” word in regards to the modem due to Samsung’s new product page presenting a graphic representing the modem/AP in a way that seems strikingly similar to a SiP (System-in-Package) solution, as opposed to an on-die solution.
The Exynos 8890 is announced to enter mass production in late 2015. With just six weeks left in the calendar year this likely means we’re already seeing silicon being etched as we speak, just in time for Samsung’s new Galaxy flagship early next year.

For the past week, I’ve been working on a review of the iPad Pro. For better or worse it has been a very quick week and I’ve been working on the review right up to the embargo time. Rather than rushing out our review of Apple’s first large-format tablet in an incomplete state, I’m going to hold it back so that we can get it right and produce the kind of high-quality article that we’re known for.
Instead for today’s embargo I want to take a more personal look at one segment of the iPad Pro’s new features as a preview of things to come. The iPad Pro is a tablet of several firsts for Apple – their first large-format tablet, their first tablet with Apple’s A9X SoC, and their first tablet clearly geared towards productivity as opposed to content consumption – and as a result one area that’s worth discussing in depth is whether or not the iPad Pro is useful to people that might not have wanted or needed an iPad before.
