Samsung Unveils the Latest Application Processor, Exynos 8 Octa, Built on 14-Nanometer FinFET Process Technology

he Exynos 8 Octa is Samsung’s first application processor to include the company’s initial premium custom CPU cores based on 64-bit ARMv8 architecture providing over 30 percent improvement in performance and 10 percent in power efficiency compared to the Exynos 7 Octa. This chip also supports enhanced heterogeneous multi-processing for efficient usage of the eight cores, four custom and four ARM® Cortex®-A53, to deliver the highest performance and power efficiency in its class.

For a graphic-intensive user interface, highly immersive 3D gaming and life-like virtual reality experiences, the Exynos 8 Octa employs ARM®’s latest GPU, Mali™-T880.

Samsung plans to begin mass production of the Exynos 8 Octa in late 2015.

finalmente a Samsung parece disposta a dar o próximo passo, e finalmente a dar uso ao pessoal que tinha andado a contratar (especialmente ex-AMD), para o seu Samsung Austin R&D Center.

Bem, se coseguiram 30% melhor performance e ainda reduzir consumo em 10%... É uma grande notícia. Parece que deu uns frutos interessantes essas contratações E falamos de valores de performance visíveis!

 

[Gaugamela]

O mais interessante é que vão usar o mesmo processo de fabrico que os CPUs da AMD. Isto para mim confirma que tanto um chip como outro vão mesmo chegar no primeiro timestre do próximo ano.

Quando o pessoal da ODROID ou similar encaixar isso numa board, e a Lima suportar essa T880, já dá para qualquer coisa.
Calculo que 99% da utilização disto sejam os telemóveis de alta gama, mas cá eu continuo à espera de portateis e mesmo desktops com esses chips.

Early Exynos 8890 Impressions And Full Specifications

On the CPU side we find an 8-core SoC composed of 4x Cortex A53 cores running at up to 1.586GHz coupled with 4x Exynos M1 cores in a big.LITTLE configuration. The most surprising revelation was the fact that the M1 cores reach an extremely high clock of up to 2.6GHz. This represents quite a significant boost over some past rumors which had put expectations 2.3-2.4GHz maximum frequency range. The catch here is that the Galaxy S7's power management doesn't allow all four cores to run at this high frequency but rather only enables the maximum clock when there's at most 2 cores loaded. If there are 3 or more cores under high load, the CPU frequency doesn't surpass 2288MHz.

Curiosos que o M1 permite uma espécie de modo Turbo, que permite que quando apenas com 2 cores possa aumentar a velocidade de relógio, no artigo da Anandtech dizem que este também "aquece".

É perna não estar aí o G5 no GFXBench pois pelo que se tem visto noutros dispositivos os Mali da ARM estão uns bons tacos abaixo dos últimos Adrenos...

Hot Chips 2016: Exynos M1 Architecture Disclosed

At a high level, Samsung pointed out that the Exynos M1 is differentiated from other ARM CPU designs by advanced branch prediction, roughly four instructions decoded per cycle, as well as the ability to dispatch and retire four instructions per cycle. As the big core in the Exynos 8890, it obviously is an out of order design, and there are some additional claims of multistride/stream prefetching and improved cache design.

Exynos 9 Series Processor Built on the World’s First 10nm FinFET

Exynos 9 Series 8895. This is Samsung’s first processor chipset to take advantage of the most advanced and industry leading 10-nanometer (nm) FinFET process technology with improved 3D transistor structure, which allows up to 27% higher performance while consuming 40% less power when compared to 14nm technology.

Exynos 8895 is an octa-core processor, comprising of four of Samsung’s 2nd generation custom designed CPU cores for improved performance and power efficiency in addition to four Cortex®-A53 cores. With Samsung Coherent Interconnect (SCI) technology, the latest processor integrates a heterogeneous system architecture that allows faster computing for a wide range of applications such as artificial intelligence, and deep learning.
