The SD810 was TERRIBLE, so 2x SD810 should be doable. Especially if their internal benchmarks stress test (since SD810 perf drops significantly under heat)
It wasn't THAT bad. If it doubles performance (in what area?) in geekbench that would give it a single core score of around 2600-2800(or WELL into high powered Intel territory). To be clear, I'm not expecting that. What I do expect is it scoring around 1900 for a single core, and 6000-6500 (closer to the lower end of that range) for all four
Up to 2x when you factor in the work on DSP and GPU. But what exactly will use GPGPU is unclear ,especially if the DSP does image manipulation. When a company has a good product there is no need for vague and misleading numbers so i see this as a red flag. Hoped for 60-80% gain over a cool SD810 but some rumors of 35% CPU gain and this today make me wonder if Kryo is slower than what A72 is supposed to deliver, if A72 can reach it's targets. If Kryo and A72 are close, power and die area can make a difference so we'll see. Messing this one up would be a multi-year problem and given the lack of competition in the high end it wouldn't be all that great for us.
I think they ment general purpose CPU cores performance & I am certain that 2x gain is overstatement same as we can say that cortex A53 is up to 2x faster in some tasks than A7 but overlay performance gain is about 35%. Spectra which is basically just a large SIMD aria (2x1024 bit) (a bit similar to AVX in purpose at least) do most more frequent FPU - VFP tasks helped bi DSP in those more paralel, basically most multimedia stuff. Knowing how Qualcomm mixes smaller core logic with bigger ones cutting bigger ones I am not convinced it will be faster then A72s but it will probably be more power efficient. We will see soon enough.
The quote is "With Kryo CPU and Snapdragon 820, you can expect up to 2 times the performance and up to 2 times the power efficiency when compared with the Snapdragon 810 processor." That's not a phrasing you use if you mean CPU and there is a strong emphasis on the DSP and in their announcement. Looking at it another way, why push expectations that high and then fail to deliver (seems pretty hard to actually deliver on 100% CPU gain). If you have a great product you still want to surprise on the upside at launch so this just feels off.
UP TO 2x. which means when you draw the performance/power curves for both, there is at least one point where you can say "at this power, X performs at twice Y" and one point where you can say "at this performance level, X is using half the power of Y".
The 810 wasn't actually all that great under benchmarks. Doubling it's performance means it is still likely to be less powerful than next week's iPhone 6S.
The problem is WHEN. It seems Nvidia is first this xmas (for nov devices I'd say, with apple sept 9th), as Qcom seems to be quite late with this. Note there is no date on this pic for when it's expected. With a 14nm Finfet chip, I'm wondering if NV can use their own modem in some cases, and like Intel use Qcom for MU-Mimo if desired (see recent chromebooks with Intel pairing qcom). With power dropping so much from die shrinks, there isn't much need for on-die crap now if NV's old 150 modem can't get the job done. I'm wondering if Nv could get into top end phones even if they have to use Qcom modem (or samsung, considering the suit, maybe they'll get a deal).
Either way, Qcom is late, which is why samsung dumped them and why their stock has plummeted over the last year (along with china cheapo socs/currency manipulation etc hurting stock price too).
Who cares, Nvidia's SOCs have been shit for years now. Sure Qualcomm's late, and dropped Samsung and other valuable clients this year because the 810 sucked. But assuming the 100% increase in efficiency/power is correct they'll pick up all their contracts again next year, as that beats the hell out of Samsung's custom cores and the Cortex A72.
Well, for Denver you can always blame their on-the-fly translation business, which conceptually will always bench better than it runs "real world" day-to-day.
"as that beats the hell out of Samsung's custom cores"
How do you know that when neither are out on a device? There have been rumors of quite the opposite actually. Anyway, Qualcomm is comparing the 820 with a chip that sucked big time. Not the best comparison you know...
Huh? They've always been good for when they're launched. I've never been impressed by anything Qualcomm's done. They're "okay" generic phone CPUs, but nothing exciting.
Nvidia is unlikely to go back to smartphones soon, what you should really be expecting is the MediaTek X20 and HiSi Kirin 950 for higher end chipsets. Intel still has nothing to offer for top tiered SoCs yet, which may change soon in 2016
Mediatek is going 16ff in the first half of 2016 in the high end (and in the second half in the mainstream) so X20 will likely have the lead for a few months ahead of SD820 and then we'll see when x30 or w/e arrives and if it can compete with SD820. We'll see if X20 can hit it's 2.5GHz clocks, would be great if it does but i guess it would be ok at 2-2.2GHz too before their 16ff product arrives. Huawei doesn't seem quite ready to compete so i wouldn't hope for too much. Samsung and LG should have their own SoCs too next year and maybe Spreadtrum goes for the high end on 14nm Intel.
I mean the Kirin 950 with quad A72 with T880 seems promising, but much like Samsung they are for in-house products. I think the biggest game changers next year will be MediaTek and Intel. For now it's even a 50/50 for whether Samsung will continue to their Exynos or not for S7
I was aware what you mean but so far Hisilicon hasn't been so great. On the memory side, on the GPU side so i wouldn't expect them to be better competitive even if they use the same core and GPU as others. At some point they will ,maybe even as soon as now but based on their record i'm reluctant to expect too much from them just yet. Oh and Hisilicon is actually trying to sell to others. As for Samsung,they'll always go with the best solution no matter if it's internal or not. A game changer wouldn't be in the high end. A dual A72+ some A53s (instead of 8xA53) at 20$ would be a game changer. Would enable Xiaomi, Meizu and the likes to make really fast 150$ phones.
Nice try, buddy. When phone manufacturers have endured Tegra 2, 3, 4, and 4i, you can bet your a** that they're not going to try anything with Nvidia again.
It would be hard for them. NVidia has lost its hype edge. Marketing a device as having a Tegra inside doesn't have a big impact anymore. There's also the issue of integrated modems that NVidia dropped.
It's going to be VERY hard for them to compete with QC and Samsung in the high end without a complete package. It's also very hard to compete with Mediatech and other Chinese chips in price for the mid to low end...
I believe they should be focusing more on tablets. Microsoft, in particular, should strike a good deal with them to build a chip with a huge, relatively efficient, GPU to be the minimum requirement for Windows 10 Mobile (tablets and phones). They have the edge in Windows for GPU drivers, which would then be a standard for Games to evolve on the platform with DX12 and most games would target that performance level for optimization. But it also seems that Microsoft is going the Qualcomm route.... Oh well.
Well Nvidia gave up on their modem division and on the whole smartphones idea because they said they couldn't make enough profit from it. In reality they didn't seem to manage to make a powerful SOC so of course they couldn't charge as much as they wanted for their average ( at best ) ones ... Mediatek is a force to be reckoned with and the only real competition for Qualcomm right now. Intel is trying something but they're always late with their SOCs so by the time theirs are out they can't really compete with the top ARM SOCs.
They simply used old nodes for decent cores. Denver, had it two A53 cores ( they were out then), would have been great, They actually beat Apple's custom cores at the point they came out. Their SW issues have plagued them and general wider adoption.
When you have a reference device, you make it perfect. The nexus 9 could have, if executed well, pushed the Denver cores into a lot of chromebooks ( at the very least) and other android tabs.
Mediatek isn't too interesting, IMHO. They don't balance cpu/gpu well. They don't create their own designs. They seem to be pursuing hype over user experience with the use of such high clocked little cores (way out of their max efficiency range). Their, unreleased (illegal given the kernel's license) kernel changes don't seem to be very good. LG might be interesting.
Sure the old Nokia's had heaps of battery life but that was because you never do anything with them- I only ever used 3G when it was absolutely necessary. The internet experience was great at the time but compared to any modern smartphone is down right awful, if I limited my LG G2 to a 320x240 256 color ~ 1.8" across screen it too would have battery life for days. (See Galaxy S5 and ultra power saving mode)
It will be worse than a OLED based screen, because you actually have all of those "black" pixels off. On and LCD theyre always on, just hide from your eyes.
The Motorola Droid Maxx (not the Razr) is the closest I've ever come to finding a week+ smartphone. The specs aren't that great but I do have screenshots showing 7d 2h 21m on battery with 12% left, brightness at auto, 2h 36m screen on time, cellular data and wifi were both enabled the whole time and the phone was going back and forth between home and work every day. This was after two days of battery charge and drain immediately after pulling it out of the box for calibration and pretty much everything else was stock other than the 3-4 apps I downloaded. Not quite enough screen on time for me to call it a solid week long contender but certainly the closest I've ever seen and what I would call your only viable option so far. It does meet your requirement for 7d on battery.
Side note: it lasted 3d 2h 13m with 8% left, 4h 30m screen on time, 1h 21m voice calls, and 1h 7m playing Injustice (fairly resource intensive game), everything else set the same. That's what I would consider reasonably heavy use compared to the 7d I got with significantly less use.
hi5 from another G2 owner.I am still struggling to find anything to replace it with. Z5 5.2" or LG Nexus 2015 might be close though. hate how manufacturers went above 5.2/fullhd screens for flagships ruining battery life as result
I have a question.. and it's serius. I own a Lumia 1520 32gb w/ 128gb microSD running Windows 10 Mobile. It has a SnapDragon 800 Chipset. I like it. No complaints. Very fast. Very reliable. Great 4g LTE performance. It's just an incredible smartphone to use. The SnapDragon 810 is faster. So why do you all say it stinks because occasionally it got warm. Did it slow down to subpar SnapDragon 800 performance, or was it that it just didn't perform as well on the Pop website synthetic benchmarks? No, I'm serious. Are phones built on the 810 slower than my Lumia 1520 built on the 800?
No the 810 is easily faster than the 800. You also have a Windows Phone which is running a much more efficient and smoother appearing OS than Android, due somewhat to the fact that Microsoft had access to some Apple tech that went into IOS, but mostly because Windows Phone is a much less adaptable OS.
The issue here is probably mostly power consumption, which is affected by the strain placed on a chip by general tasks ie a more powerful processor doesn't have to do as much work to get the job done. In both raw performance, and power consumption, the Samsung exynos 7420 WALKS on the SD810. Like 50% faster minimum. That is really telling of where Qualcomm should be right now.
Another thing is that Qualcomm typically has a custom soc that is quite superior to arm's generic chip offerings, and the fact that their top product is entirely based on arm's generic processor cores is a problem.
Yeah, the problem is mostly that the competition (Samsung) is better.. and that OEMs but SD810 in designs with insufficient cooling capability given how hard they push the CPUs. Using aluminum instead of plastic, or dropping the top performance state by 100 MHz under 4-core load might have been enough to stop thermal throttling below SD808 performance.
No one is using plastic days, I hope at the very least, to cool smartphones. even aluminum isn't the best, what you really want is all that copper heat spreader
Don't underestimate the "Android tax". Windows Phone (both 7&8) is a newer, much more efficient design, that wasn't plagued with some of the baggage that Android had.
Things like Dalvik/Java, Android being hard to fine tune for a particular CPU, and Android not really being designed for a cellphone OS in the first place.
It's also for that reason that both iOS and WP both seem to be fine and snappy on 512MB RAM (or even just 256 MB) while Android needs at least 1024 MB if you want to avoid lag.
If Android wasn't designed for cellphones, then what was it designed for? Surely not tablets because they weren't a thing back when Android was first being made..
I wouldn`t call WP "snappy" on 512MB. Sure, it works well, but there is a noticeable slowdown compared to 1024MB when I`m returning to a background Fictionbook Reader application, for example. I wonder how it will be in 10.
Again, please explain the "more efficient' claim. The Android kernel has included a few nice tricks for memory compaction included deduplication for large pages, memory compression using the clean cache(transcendent memory) mechanism. So, it can on devices with memory as low as windows, and it certainly can do the same amount of work with a given energy budget.
With all the cute tricks, it`s still sluggish. I`ve recently installed cyanogen`d 5.1.1 with some additional performance shamanism on OMAP4460, which should be adequate performance-wise as long as you`re not playing games, and interface stuttered all the same.
Telling me your about your experience with software you installed doesn't say much about the platform. Have you tried installing windows on it:) By the way, nice bit of passive aggression. Those "cute tricks" are of what engineering consists. I think the nt kernel may have some of them as well.
Running (almost) real Windows 8.1 vs Android on the same Tegra 3 SOC, Windows runs fine, feels fine, aside from some websites with really crazy scripting. Android on the other hand is a sluggish mess on that same hardware...which is a joke given we're talking about a full OS being used as a desktop versus an incredibly stripped down phone thing.
I don't know what "(almost) real" means, nor "stripped down phone thing". The T3 was always an issue because of bandwidth to the gpu so a less graphically intense os would definitely run better. Also the storage matters A LOT. Unless you are running them on the same device you can't really compare. The same soc isn't enough.
Can you please provide evidence for your claims? Without a doubt the efficiency claims are simply incorrect unless you mean something different than "getting X amount of work done while using Y amount of energy".
Windows Phone is "much less adaptable"? It runs on the same frickin' kernel as desktop Windows.
The reason Android still lags and will forever lag is because it doesn't prioritize the UI thread, so anything that runs in the background can interrupt the animations and block out the user's touch input.
It won't forever lag, but, as I said elsewhere, Linux designs for throughout first. So it didn't weight niceness as much as it could if it were using the strictest priorities the rt patches provide.

No the 810 is easily faster than the 800. You also have a Windows Phone which is running a much more efficient and smoother appearing OS than Android, due somewhat to the fact that Microsoft had access to some Apple tech that went into IOS, but mostly because Windows Phone is a much less adaptable OS.The issue here is probably mostly power consumption, which is affected by the strain placed on a chip by general tasks ie a more powerful processor doesn't have to do as much work to get the job done. In both raw performance, and power consumption, the Samsung exynos 7420 WALKS on the SD810. Like 50% faster minimum. That is really telling of where Qualcomm should be right now.
Another thing is that Qualcomm typically has a custom soc that is quite superior to arm's generic chip offerings, and the fact that their top product is entirely based on arm's generic processor cores is a problem.

Yeah, the problem is mostly that the competition (Samsung) is better.. and that OEMs but SD810 in designs with insufficient cooling capability given how hard they push the CPUs. Using aluminum instead of plastic, or dropping the top performance state by 100 MHz under 4-core load might have been enough to stop thermal throttling below SD808 performance.Buk Lau - Friday, September 4, 2015 - link
No one is using plastic days, I hope at the very least, to cool smartphones. even aluminum isn't the best, what you really want is all that copper heat spreaderV900 - Thursday, September 3, 2015 - link
Agree...Don't underestimate the "Android tax". Windows Phone (both 7&8) is a newer, much more efficient design, that wasn't plagued with some of the baggage that Android had.
Things like Dalvik/Java, Android being hard to fine tune for a particular CPU, and Android not really being designed for a cellphone OS in the first place.
It's also for that reason that both iOS and WP both seem to be fine and snappy on 512MB RAM (or even just 256 MB) while Android needs at least 1024 MB if you want to avoid lag.

If Android wasn't designed for cellphones, then what was it designed for? Surely not tablets because they weren't a thing back when Android was first being made..Michael Bay - Thursday, September 3, 2015 - link
I wouldn`t call WP "snappy" on 512MB. Sure, it works well, but there is a noticeable slowdown compared to 1024MB when I`m returning to a background Fictionbook Reader application, for example.I wonder how it will be in 10.

Again, please explain the "more efficient' claim.The Android kernel has included a few nice tricks for memory compaction included deduplication for large pages, memory compression using the clean cache(transcendent memory) mechanism. So, it can on devices with memory as low as windows, and it certainly can do the same amount of work with a given energy budget.
Michael Bay - Thursday, September 3, 2015 - link
With all the cute tricks, it`s still sluggish. I`ve recently installed cyanogen`d 5.1.1 with some additional performance shamanism on OMAP4460, which should be adequate performance-wise as long as you`re not playing games, and interface stuttered all the same.tuxRoller - Friday, September 4, 2015 - link
Telling me your about your experience with software you installed doesn't say much about the platform. Have you tried installing windows on it:)By the way, nice bit of passive aggression. Those "cute tricks" are of what engineering consists. I think the nt kernel may have some of them as well.

Running (almost) real Windows 8.1 vs Android on the same Tegra 3 SOC, Windows runs fine, feels fine, aside from some websites with really crazy scripting. Android on the other hand is a sluggish mess on that same hardware...which is a joke given we're talking about a full OS being used as a desktop versus an incredibly stripped down phone thing.tuxRoller - Friday, September 4, 2015 - link
I don't know what "(almost) real" means, nor "stripped down phone thing".The T3 was always an issue because of bandwidth to the gpu so a less graphically intense os would definitely run better. Also the storage matters A LOT. Unless you are running them on the same device you can't really compare. The same soc isn't enough.

Can you please provide evidence for your claims? Without a doubt the efficiency claims are simply incorrect unless you mean something different than "getting X amount of work done while using Y amount of energy".Wolfpup - Friday, September 4, 2015 - link
Apple tech? Less adaptable? Android is just kind of a kludgy, gross mess that's really inefficient compared with Windows NT.tuxRoller - Friday, September 4, 2015 - link
What do you mean by "kludgy, gross" and "inefficient"?sonicmerlin - Friday, September 4, 2015 - link
Windows Phone is "much less adaptable"? It runs on the same frickin' kernel as desktop Windows.The reason Android still lags and will forever lag is because it doesn't prioritize the UI thread, so anything that runs in the background can interrupt the animations and block out the user's touch input.
tuxRoller - Friday, September 4, 2015 - link
It won't forever lag, but, as I said elsewhere, Linux designs for throughout first. So it didn't weight niceness as much as it could if it were using the strictest priorities the rt patches provide.nidz109 - Saturday, September 26, 2015 - link
>doesn't prioritize the UIThis was proven to be false. You don't know what you're talking about.

Is there any mention of sensorcore, by the way?Pessimism - Tuesday, September 8, 2015 - link
Wake me when they make one of these that can run 100% duty cycle without throttling inside a cell phone.
