Exynos 7 octa-core chip from Samsung offers a 57% gain in performance over previous generation chip
In the midst of the news about Google's new Nexus devices, which were announced today, Samsung rolled out its new Exynos 7 octa-core chip. The chip comes with four Cortex-A57 and four A53 Cores as it employs the big.LITTLE architecture. The new chips are built using the 20nm process. Samsung says that the chip supports 1440 x 2560 and 1600 x 2560 resolutions, and that the SoC uses less power than previous Exynos silicon did. Speaking of the Exynos 5, Samsung says that the Exynos 7 brings a 57% increase in performance from the previous generation chip.

The SoC comes with the upgraded Mali T-760 GPU, which is an improved version of the GPU that is already used on the Exynos 5 chip. Perhaps the international version of the Samsung Galaxy Note 5 will be employing these chips when the next iteration of the high-end phablet launches in about a year from now.

A device powered by the Exynos 7 Octa can simultaneously record high definition video using the back and front-facing cameras. This is because of the built-in dual Image Signal Processor (ISP). This feature supports 16MP 30fps (rear) and 5MP 30fps(front) video capture during simultaneous video recording.

You can check out some more features about the Exynos 7 Octa, in the slideshow below.


Thanks for the tip!

57% improvement is nothing to write home about especially for a 2015 product.

Snapdragon does increments of about 20-30% so this is a relatively large improvement.

That why competition such as Nvidia Tegra K1 is important.

Depends on what, from last years Snapdragon 800 to this years Snapdragon 805 it's more like 15-20%, so 57% is actually HUGE compared to that.

Also 57% improvement over which specific Exynos 5 Octa?
E.g. 5420 (Note 3), 5422 (S5), 5430 (Alpha) and 5433 (Note 4)
The Exynos 5430 is almost on par with the 805
The 5433 is already quite a decent improvement over the 5430

The Exynos 7420 sounds like it will be great

I guess is over Exynos 5420.
But the difference is not that big among the 5420, 5422 and 5430.
The only one with a significant performance increase is the 5433 as it uses A56 cores instead of the A15.

Exynos5433 is THE exynos 7

This is already being used in note 4

The biggest deal about this new chipset is the introduction of the new Cortex A-57 cores. We've had Cortex A-15 for the past few years, and Cortex A-57 is a huge improvement over it's predecessor. This type of CPU technology is going to bridge the gap between what we define as mobile processors and desktop grade processors even more.

This goes neck and neck with the K1 so I fail to see how this isn't great.

Because the K1 Denver is only a dual-core processor.

higher core does not necessary translate to higher processing power

29. RebelwithoutaClue (Posts: 2693; Member since: 05 Apr 2013)


But the K1 Denver has 7way superscalar, while Cortex A57 only has 3way superscalar. It might only be a dual core but excels in other areas.

32. vincelongman (Posts: 4081; Member since: 10 Feb 2013)


This is really important
Its the main reason why the Apple's dual core A7 and A8 (both 6way superscalar) are more or less on par with the quad core 800/801 and 805 (all 3way superscalar)
Also the K1 has slightly more cache than the A7 and 805

Exynos 7 and Snapdragon 810 on the Note 5. You heard it here first.

I agree with the SD810 on the Note 5, but I think the Exynos might make its appearance on the international Galaxy S6.

19. g2a5b0e (Posts: 3713; Member since: 08 Jun 2012)


I'll have to disagree here, Smurf. We will see the 810 on the S6. The Note 5 will see an even better 64-bit chip.

Hoping Qualcomm can finish Krait 500 for the fall, but they better be announcing it soon then if they want to make it to the fall out earlier. They announced 810 in April and that won't be ready until January or February. Still some time and hope left though.

+1. I agree. Qualcomm does seem to be taking their time on release cycles.

Actually if Samsung can somehow find a way to product enough Exynos 7 chips for Galaxy devices then it might not use 810 at all. Since Note 4 all Exynos are supporting LTE as well. I think the only reason why Samsung went with SD 805 was because they couldn't manufacture enough Exynos chips in time.

but we'll see what happens when the time comes.

They've been using that excuse for years. It's bullsh*t. The Note 2 had an integrated LTE chip. If you remember, there was no Snapdragon version. Samsung could very easily produce enough Exynos chips for all their phones if they wanted to. For some reason, they choose not to. I have no idea what that reason is, but there must be something advantageous to them using both.

posted on 16 Oct 2014, 07:16

38. tech2 (Posts: 3347; Member since: 26 Oct 2012)


Yes but if you remember it takes more space since LTE was not SoC. So maybe due to space restriction they decided to skip that in Note 3 onwards.

I don't know what benefits them by doing both since not only the Snapdragon chip costs more but also they need to issue separate software updates for both.

I, personally, think its only due to production constraints

Snapdragon S4 Pro,600,800 were beasts in 2013 but I don't see Snapdragon 801 and 805 are that good in 2014. Hope Snapdragon will be back with 64bit 810,815,etc in 2015.

"This feature supports 16MP 30fps (rear) and 5MP 30fps(front) video capture during simultaneous video recording"

did I read that right? 16MP video @ 30FPS? 4K video is only around 8MP, so 16MP video would be pretty detailed :)

Thank you. Question if I may ask, what would you personally do. Get the Nexus 6 or any other 805 32 bit smartphone, wait till early next year possibly to grab next-gen 64bit smartphones, or do you just not care about 32bit vs 64bit?

Besides the benefits of the 64-bit architecture, you would realize benefits from the ARMv8 instruction set, so it will be a big deal for Android once it arrives. It's still a head scratcher as to why they are launching a 32-bit Nexus phone and a 64-bit Nexus tablet, though.

I don't know what they were thinking when the gave the Nexus 6 a 32bit system. It's my only reservation for getting the phone at this point. But I feel like I may wait to see the benefits of the ARMv8 instruction set.

Hmm, I did a reply but it disappeared. I'd wait for the new 20nm 64-bit generation, i.e. 810 or 808. 805 is probably the last 32-bit in the 8xx series, it's built using 28nm.

With Qualcomm sampling the 810 right now, it seems strange that Google is pushing out a 32-bit Nexus 6. Another than Android L, which runs fine on the Nexus 5, I don't see the point. There are already QHD phones on the market for developers. I especially don't see the point of pushing out a whole bunch of carrier versions of the Nexus 6.

[September 18] "Qualcomm has received the first samples of the Snapdragon 810 from its manufacturer and the chip will be in products in the first half of next year, said Raj Talluri, head of product management, in a speech at the start of Uplinq."

Google releases a phone around this time each year and the specs are in line with other devices. The 64 bit Nexus will come this time next year.

24. 0xFFFF (Posts: 3806; Member since: 16 Apr 2014)


So why not a Nexus 5S instead of the Nexus 6 whale? Is there something in Android L that needs QHD? The Nexus 6 just seems pointless and pricy.

I can even understand the pricey, but a 64-bit tablet and 32-bit phone is just wrong. They have just opened the door for Samsung to release the first 64-bit Android smartphone, which will make Sammy the de facto flag bearer for Android once again.

43. TerryTerius (Posts: 1526; Member since: 10 Apr 2014)


That very reason may be why they didn't. Googles' diplomacy with Samsung is a give and take. Maybe they eased off from doing so to let Samsung be the first to bring 64 Bit to a "flagship" device (remember, HTC already has a midrange one) to let them have the bragging rights. In the grand scheme of things, I doubt it matters to Google who does so as long as ttheir offerings are on board.

So what's the difference between Exynos 7 and Exynos 5433, which is also using the 20nm process, 4 x Cortex A57, 4 x Cortex A53 and Mali-T760? Though I'm sure about Mali-T760, it's supposed by AnandTech.

They are actually the same. But changing names is probably for marketing purposes IMO.

Note4 with Exynos is 64-bit.

As far as I know the Exyons 7 and the Exynos 5433 are the same chip. As the latter has dissapeared from Samsung web pages:

Note 4 with Exynos 5433 apparently is not 64 bit enabled at the moment, according to Anandtech, but not sure if it can be enabled via a firmware update...when it is being fed the Lollipop....

I hope that the fact this processor uses less power does not mean they will start skimping on the battery to make it thinner. Who am I kidding? Of course they will.
