New Samsung Exynos 5 Octa: 20% more CPU power, twice the graphic capabilities
0. phoneArena 22 Jul 2013, 23:31 posted on
Last week, Samsung told us to expect the introduction shortly of an evolved, enhanced version of its Exynos 5 Octa-core processor; on Monday, the chip was unveiled and the new Samsung Exynos 5420 will include a six-core ARM Mali-T628 GPU that handles 3D graphics twice as fast as the previous Exynos 5 Octa-core...

What Battery efficiency? Go and read Tech2's comment below.

Yes, surely better than 5410.
When I knew about the Imagination's GPU SGX544Mp3 inside the Octa 5410, I doubted that how could it works with CCI-400 (a very important part of big.LITTLE architechture) because it can only work with a ARM's GPU. And the fact showed after that 5410 does not have CCI-400, and that's why there is no "pair" of a Cortex A15 and Cortex A7 as many said before
Now, this one is an ARM's GPU, and I'm sure that Samsung includes CCI-400 into it. The battery efficiency is much better.

It is actually. 5420 supports full GTS (Global Task Scheduling).
It will debut in a chromebook first, then Note 3 probably. (Source: XDA dev AndreiLux).
5420 can use any combination of the eight CPU cores at a time.
There is already a working GTS implementation in Linaro codebase:
Yes, I am 100% sure that it will have a properly working CCI in 5420 :)

That would mean that the S4 is already running on old specs.

20% more power, twice the graphic abilities; 40% more battery consumption, twice the heat production. Samsung missed out another 2 features.

Dog headed with a grudge against Samsung. Don't waste your life away hating..

I give credits to any company when due, but i have not been impressed with what Samsung has been doing. Their Exynos processor-powered phones has a lot of issues, and even with countless "improved" ones the problems are still there, not to mention the one in the S4 still lack proper LTE support.

Exactly. They are the first to open the article and reply and show the world pathetic they sound. Such people think they have better understanding of the chip by reading an article than the entire engineering team who spend months working on them.
@EXkurogane, Do you realize its not the battery consuming PowerVRSGX544M3 from the GS4 ? Also, its only overclocked by 0.2 Ghz how would that increase the heat consumption to twice ?....smh
TBH, I wasn't expecting much, just some usual updates but I was really taken aback by the twice the GPU. Already GS4 had one the most powerful GPU (if not the most power efficient). Its like the best of SD800 (processing) & Tegra 4 (GPU) put together. Awesome !
6. EXkurogane (Posts: 863; Member since: 07 Mar 2013)
I was being partially sarcastic. But im indeed concerned with the GPU boost because that does produce more heat. My country has both S600 and Exynos versions of Galaxy S4 available, consumers get to choose, and you wont believe how many dumb consumers went for Exynos and sacrificed LTE thinking they could get DOUBLE processing power seeing Exynos has 8 cores when it is not exactly the case.
It is indeed a bit faster than snapdragon 600, but far from double, just a slight bit faster - and only in benchmarks.
28. tech2 (Posts: 3462; Member since: 26 Oct 2012)
The GPU in GS4 was from 2010 and it was well documented that it is a battery drainer but Mali have a proven track record of power efficient GPU. It was developed later in 2012.
OMG, if Exynos Octa 5410 was a bit faster than sd600 in your own words then if Samsung says it will be twice better in GPU department than of course it will even beat out Adreno 330 in SD800 no doubt that too without draining that much of battery with Mali GPU !

S800 doesn't have the best processor. Cortex A15 is a much faster than Krait. Tegra 4 has the best processor along with the best GPU. S800 excels in Perf/watt. That's why we are seeing S800 on 5" slim phones like Galaxy S4. But we won't see Exynos 5420 or Tegra 4 in phones anytime soon.

You mean the exact Quadcore Cortex A15 @ 1.8GHz (and could never fit into a phone) is some how "better" ? And a GPU without Unified Shader let alone Open GL ES 3.0 is "the best" ?
23. ollienightly (Posts: 37; Member since: 23 Jul 2013)
All things considered, S800 has a better/futureproof GPU.
33. tech2 (Posts: 3462; Member since: 26 Oct 2012)
Cortex A15 is faster but a battery drainer thats why they failed to gain traction until the big.LITTLE architecture. Tegra 4 runs on A15s all the time so you can expect the battery life on that thing. Plus the 72 core GPU will not be helpful in anyway to conserve the battery as well.
Samsung released the GS4 with Exynos Octa 5410 after 3 months of uneviling the processor. Why do you think they won't do the same with Note 3 ? They can very much land in the devices within 3-4 months.

Nah, 20% more power isn't always translated into more battery consumption. Perhaps samsung change the CPU architecture & fix the design failure so that with the same amount of silicon, it can produce more power but keep the battery consumption at the same level. You won't say that stupid thing if you follow the progress of CPU & GPU in computer... Remember how Nvidia GeForce GTX 480 is replaced by GeForce GTX 580? GTX 580 has almost the same amount of transistor as GTX480, has the same silicon technology (40 nm), but GTX 580 has better power consumption & more processing power.

I hope this has a working Cache Interconnect. Otherwise this too will be a failure.

watch-out snapdragon...new beast unveiled....exynos 5420 FTW...
15. flynfree (Posts: 374; Member since: 09 Jun 2013)
Exynos 5425 cpu + arm mali 628 gpu = perfect combi for gnote 3 with lte advance.
It look like worth upgrade from galaxy nexus I9250,
16. flynfree (Posts: 374; Member since: 09 Jun 2013)
Yeah, right! When you're not satisfied with the original battery and use third party cheap battery.

Based on my testing and review from owners . The LTE model of the s4 is smoother and more stable than the s**tty octa

well damn...Qualcomm, you may need to start thinking about getting a Snapdragon 810 out soon.
17. james004 (Posts: 486; Member since: 15 May 2013)
Wish companies were racing for better and advance battery just the same way they compete for screen and processor.
40. _Bone_ (Posts: 2154; Member since: 29 Oct 2012)
But they are. That's what the new Krait, Haswell or big.LITTLE architecture is all about.
42. james004 (Posts: 486; Member since: 15 May 2013)
you are talking processor. im talking battery. someone needs to take first step, leave Lithium-ion alone move to another element, something that holds charge for longer, charges faster. that sort of thing. and dont say that im dreaming because Engineering universities keep making newer battery every year that is best prototype of its time so why not bring it in commercial use?
18. Thefraggot (Posts: 21; Member since: 09 Jan 2012)
Still no match to my laptop with i7 processor. ;)
19. Thefraggot (Posts: 21; Member since: 09 Jan 2012)
Why not buy a powerful laptop instead of this phone ?
