Note 3 and Galaxy S4 won't be getting the full eight core Exynos performance patch, says Samsung

Note 3 and Galaxy S4 won't be getting the full eight core Exynos performance patch, says Samsung
Note 3 and Galaxy S4 are unlikely to receive the full octa-core power in their Exynos chipset versions, advised a chief technical expert from Samsung's Mobile Solutions department. Recently the company said that it is able to unleash all the eight cores working at once, which can bump performance significantly, compared to the maximum of four cores restriction we have now with Exynos 5 Octa in these handsets.

The thing is, the engineer comments, that even though Samsung can release a software patch that will allow both the quad-core Cortex-A15 set, and the frugal Cortex-A7 cores, to get together for a task, the thermal envelope of these Exynos chips hasn't been cut for the job. 

Thus there might be issues with heat dissipation under pressure, and it's only after the Exynos 5 Octa batches get updated with new production methodology aimed to avoid overheating in octa-core scenarios, that Samsung will unlock this ability. Since your Note 3 and Galaxy S4 are sporting the current thermal envelopes, calculated to run with only four cores at once, the fix won't apply to them, at least officially, unless you don't mind the risk of frying your handset.

On the issue of the Android 4.4 KitKat update for Samsung's flagships, the expert advised that this is still months away, and right now they are focusing on getting Android 4.3 rolled out to everyone in Q4.

And they won't get lte and cyanogenmod support either, poor Sammy

AOKP, AOSP along with custom Kernel, also other ROMS are available to download and Root! And who the hell cares if it heats up! What's the big deal? Every electric devices heat up! Just ignore touching that part, or use a case. Dimwits complaining about heats, no one says jack about PCs, Laptops and etc.....Temperature reaching 45 degrees, so what? I've overclocked my S4 Exynos, not the the kalf cooked A9 halfbaked A15 to 2.1Ghz, and GPU raised to 688Mhz, voltage settings have been raised. ™

They won't unlock it due to heat issues. Except when a benchmark app is run ;)

You are aware that the small increase it would do from overclocking itself like 100mhz is almost nothing added to the scores right? 100mhz is better but only a small amount that is negligible in real world performance. A real performance gain is like overclocked a 4670k from 3.4ghz to 4.5ghz, you would see around a 20-25% performance gain. If I go an raise my Nexus 4s clocks a couple hundred mhzthe difference in benchmarks like antutu is only 50-100 points.

Dude, it was a joke, you're way too serious.

Depends on what's being overclocked. GPUs actually make good use of a 100MHz bump. Just look at the desktop GPUs. It also depends on the CPU architecture. Sometimes 100Mhz can make a noticeable difference like on my AMD desktop processor.

Stop with this iBS(benchmark gate) Everybody see that this was iAttack against Note 3 (same iBS like the "region lock gate". All iboys fear of Note 3. LOL All power devices are optimized like that (not only Note 3). They should recognize the power hungry apps and give them as much as they can.

Poor heating issues. Come over this problem soon. :) If you don't mind the risk of frying your handset then you can ask to Sammy for full octa core at once.

Why would they do it anyway? They designed the phone to run on certain speeds, with specific hardware and on specific temperatures. Why risk the hardware with something it wasnt initially designed for. Its like overclocking your desktop PC cpu and leaving it with stock fan..

Wow, Exynos 5 Octa has been quite a disappointment.

It's the fastest processor available today, then again, what is your disappointment? It was never said to be an all-8-core performer.

800 is the fastest currently. Yes octa beats it in few tests but overall 800 is the king.

Yeah it is a big disappointment for those who never had the chance to use it or own it like yourself. Those who owned it know how well it performs when the A15 cores start kicking in.

They are still beastly chips in their current setup, so it's all good. :)

The A15s are already beating out the CPU of Tegra 4 and Qualcomm's SD800, there is no need for extra power, there is the need of proper core migration to up battery life.

So....what you're saying is that the Tegra 4 doesn't use A15s?

Of late samsung is on self-destruct mode, first regional lock for Note 3, then chafing with benchmarking apps in S4 and Note 3, and now backtracking on their true octa-core performance for Note3 and S4........ With success comes arrogance.........

I meant 'cheating with benchmarking apps'......

Head down to XDA to gain Root access! Simple! At least on Android there a options viable! Unlike other platforms that totally restricts you! ™

Yes they are really slacking off being the only company to offer a phone with 8 cores in it with a tablet level powervr GPU.......how dare they give us that for how much Apple charges for a dual core.... Jeez people are stupid when they let their biases mess up logic.

After my experience with SGS2 international version, I'm never going to buy any Samsung with exynos chipset. For me, battery performance comes first or how can I enjoy the beasty performance when the phone is always plugged to a wall socket.

Right now my exynos S4 is at 52% with 1hr 32min screen time with it being off the charger for 11hrs 38min and I have a spare battery that's fully charged. I have issues with the phone but not its battery life.

LOL! Do u remember how bad was the Sony Xperia S's battery life compared to S2? International version of S2 had better battery life and performance than the Snapdragon processor during that period especially after updating to Android 4.0

who needs all 8 cores? I get 2990 on geekbench 3 with my international note3. stock rom,if that isn't fast for you guys then i don't know what fast is. Last i checked even the iphone 5s only gets 2500

Exynos sucks. Snapdragon FTW! :D

Sounds like the octa core isnt really a octa since you cant use the whole core.
