Doubling down: the Snapdragon 830 processor might feature eight custom Kryo CPU cores

Industry analyst Pan Juitang came up with informed predictions about the Snapdragon 830 processor. The chip is internally known as the MSM8998 (the SD820 is MSM8996), and differs from its predecessor in several key aspects...

Ill be gunning for next years nexus, hopefully it will use one of these 10nm processors

Also Google is building a new unified hardware division under former Motorola chief Rick Osterloh Makes me tempted to wait until next year for the 2017 Nexus and possibly a Pixel phone

Google should purchase HTC and use its design language and amazingly premium form factor for its nexus device.

I dont think they will It would upset the OEMs again, like what happened with Moto And maybe Valve too Especially with the rumored 3 year Nexus deal

No, I want wireless charging. So get rid of the all metal back because wireless charging doesn't work through an all metal back. Also the 830 uses quad channel RAM chips, which can handle a higher throughput. It makes sense that it handle more and operate at faster speeds. Also 10nm is the biggest helping hand.

Amazingly premium form factor from HTC? In the past during M7, M8 yeah but lately nah. Even so why do they need to purchase HTC just for its design? They could just ask HTC to make their Nexus device. Unless Google wanna start making phones themselves.

Yeah go octa-core again a.k.a Oven 2.0

The purpose of octa-cores is to improve power efficiency The 810/808 were consequence of a series of mishaps by Qualcomm and also: ARM's A57 being very power hungry TSMC's 20nm not scaling well to high frequencies, still Qualcomm's fault for not changing their designs to avoid overheat like Apple, or avoid it like Nvidia/AMD I doubt this will happen any time soon

Edit didnt go though *or totally avoiding it like Nvidia/AMD's GPUs, or using it only in tablets like Nvidia did with the X1

Big little octocore are all oven S6 throttled almost as much as the SD810 devices. S7 with exynos loose 25% of speed after 15 min of gaming. At least the SD820 dont throttle as much now its might be a mistake to go back to octocore again because of voltage issues.

The S6 also has the power hungry A57s, but Samsung's better 20nm and more experience with big.LITTLE meant it didn't overheat as much as the 810 S7 throttling after 15min of gaming is because of the GPU throttling not the CPU. Samsung should have used the T880 MP16 and reduced the clock rate to improve efficiency Going back octa core could help Qualcomm catch up with Samsung and Huawei in terms of CPU efficiency

An MP16 config is too huge.

Depends Could Samsung have done it in the 8890 Yep, definitely. If they'd used the MP16 and reduced the clock rate to say 400-500MHz, it would have slightly more performance and be more efficient too So why didn't they use the 8890? Money. Using the MP16 would have increased the 8890's die size. Which would reduce yields and therefore increase costs So the MP16 is not too huge physically But Samsung believe it was too big because of the extra cost

I meant that an MP16 is too huge physically. And yeah everyone tries to reduce cost.

isn't 8 kyro means 8 all big cores?

46. vincelongman

Posts: 5653; Member since: Feb 10, 2013

No The 820 has 4 Kryo core It's actually 2 big cores and 2 "medium" cores I say medium because the 2 efficiency Kryo cores have higher performance and power consumption compared to the A53s

Second version of SD810

Because....it's octa-core?? Sometimes, read what people comment too. It's quite informative. For example, read about the technical details "VinceLongman" wrote, up there.

but they cant simply use same core while doubling the core count and increasing core clock.. that will be some extra work for OEM to figure out how to keep it cool.. (heat pipes... heat pipes everywhere...)

They probably won't Right now the 820 has 4 Kryo cores with two different configs 2 for performance and 2 for efficiency The 830 could have 8 Kryo cores with three different configs e.g. 2 for performance, 2 for sustained performance and 4 for efficiency

20. sarcastic_nerd unregistered

The 820's efficiency is pretty bad regardless. Almost all phones running the 820 have average battery life.

I've been reading that people with the Mi5 and HTC 10 are pretty happy with its battery life, getting like 5-7 hr SOT Seems like people with the G5 and 820 S7 aren't so happy, getting like 4-5 hr SOT Either way, having 8 Kryo cores with more configs should improve efficiency over the 820

25. sarcastic_nerd unregistered

SoT is pretty crappy way to judge battery life since there are so many variables. According to the tests from sites like anandtech, 10 and S7 have identical battery life, and none is great. Mi5 can be better but the software uses pretty aggressive memory and notification management, which is essentially like using a dumbphone. They don't have better battery life than 2013 phones like G2. People used to get 6 hours+ on that. And that's shameful for 3 years of advancement considering the battery capacity is the same. Here's one more thing. Exynos 8890 and kirin 950 absolutely decimate the 820 in battery efficiency. The exynos S7 gets easily over 8 hours SoT and I've seen multiple people with the S7 edge post over 10 hours SoT. Same with mate 8. I expect a 2016 flagship to at least give me 8-10 hours SoT. Else I'll just get a cheap phone since difference between flagship and midrange is diminishing, and budget phones have better battery life.

True, SoT is terrible for comparison since everyone's usage is different I've also seen people saying they get over 10 hours SoT with the HTC 10 too But their usage is probably lots of reading Even my Nexus 5 could get over 6 hr SoT by reading That being said, the 8890 and 950 do seem better than the 820 in terms of efficiency But I'd say the difference isn't as big as you

36. sarcastic_nerd unregistered

Reading is a completely different beast LOL. Anyway, according to geekbench battery test: S7 exynos(6300) S7 edge exynos(7500) S7 SD (4800) S7 edge SD(5600). I can't post links so either you'll have to believe me or go search yourself. But it clearly shows that the Exynos is about 30-35% more efficient. And since all other variables are held constant, it's a fair test. SD 820 is a failure and I'm not buying a phone with that processor unless it costs 300$ or lower.

Those are still great scores on the SD 820 e.g. the best geekbench battery scores from last year S6 edge+ (4500) iPhone 6s Plus (4000) S6 edge (4000) The HTC and Mi5 would probably get more than 4800 The Exynos is just another level in terms of efficiency That doesn't mean the 820 is a failure The 820 is still a great chip and very efficient

Exynos 8890 also throttle down like a bitch no wonder its has a good battery life lol..
