I did post this under Nexus 5 Q/A, but I realized this probably applies to all Android devices, not just the one I have. So sorry for dual-topic, but I feel this kind of belongs here more.
With the Nexus 6 announced, I was quite disappointed, as I was expecting Google to release an updated version of Nexus 5, just like they did with Nexus 7 back in 2013. I'm not a fan of phablets, and 6 inches seems too big for a phone, while Nexus 5 sure hit that sweet spot.
So I had this idea - would it be possible to replace the old existing Snapdragon processors with newer versions? 801? 805? What about the new 808/810 models? Problems that come to my mind are:
Do the newer processors have the same pin layout as the 800 version? I managed to find information that the 801 is, but I'd like to know about 805 or even 808/810.
Do different Snapdragon 8** series processors use the same instruction-set? If not, are the newer versions backwards-compatible with old versions, like for example Intel's x86?
Would the old chipset be able to take advantage of a faster processor? I know ROMs with custom kernels allow overclocking up to 3 GHz, although that's just stupid. With a 805/808/810 though... Would it be as simple as getting for exapmle CyanogenMod, "overclocking" the 805 to 2.7 GHz (what it's actually rated at), and that would be the end of the story? Or am I missing something?
How hard would it be physically to replace the processor? I imagine a skilled engineer with a soldering station would be able to do the job, or are the connections so small that it's practically impossible to do by hand?
How does one obtain a stand-alone Snapdragon processor? I can't seem to find any on Amazon. Do they even sell retail, like Intel/AMD? If not, how do I get hold of one?
What else am I missing? How feasable is this idea really?
Short answer. No.
Unlike the "Can I upgrade my phones memory?" question, this one is a much more definitive no.
From what I hear, the 810 will be the last 32-Bit Snapdragon SoC.
Meaning, even if you could (I highly doubt you can) your only improvement would be less than 0.5gHZ.
So not really worth the risk.

Hi guys!
We've all been hearing all this stuff about dual-core CPUs like Qualcomm's QSD8672 @1,5GHz,or the single-core OMAP 4xxx @2GHz etc,right?The question is,will we see those devices soon enough?I mean,if they come out some time around christmas it's worth waiting(although they may cost something too much).However all the new devices that we see coming out,like HTC Ace or Schubert,have the well-known Snapdragon QSD8250/8650 @1GHz,with its crappy GPU and its not so powerful CPU(compared to Samsung's Hummingbird).Any clues yet on when we'll see those devices that will change what high-end means?
My guess (which is based solely on a hunch) is that that such devices would be announced together with Android 3.0, so that companies can advertise it as 'the next generation'.
Well,although not based on facts,your hunch gives a pretty possible image of how things will work...
Yes I've used the search tool and the last post in the last Exynos 5250 thread was at december 2011 and I can't find any rules about reviving old threads so I don't want to fiddle with it since I might get an infraction or worse a ban and and the last Tegra 4 thread wasn't coherent enough for me.
I don't know all the details but I would like to start talking about the supposed new Exynos 5250 and Tegra 4 development so please bear with me, I need all of those who has reliable information to add in the discussion. I'd like to start things with how will it fare against this year's smartphones and tablets? specifically the Samsung Galaxy S3 (1.4 ghz Quad ARM Cortex-A9 + Exynos 4412 & 1.5 GHz dual-core Qualcomm Krait + Snapdragon S4 MSM8960) and HTC one X ( 1.5 GHz quad-core ARM Cortex-A9 + Nvidia Tegra 3 & 1.5 GHz dual-core Qualcomm Krait + Snapdragon S4 MSM8960) since they are currently the top Phones out there in the market performance wise.
Further into the topic will the new Exynos and Tegra make their predecessors completely obsolete once they come out? or is the performance leap going to be minimal at best? due to various factors perhaps you can't fully utilize their potential due to the limiting software apps out there? What I want you guys to elaborate for the community is how better will it be in terms of CPU and GPU benchmark performance. Please do share your Ideas and any reliable information about the said topic at hand.
P.S. I just got an SGS3 my very first smartphone and android, did I make a huge mistake by buying it or should have I gone for a cheaper Galaxy Nexus and waited for the new Exynos to come out?

what better than Nvidia Tegra 3
First off, let's talk processors:
Your phone, the SGS3 i9300 is packing the Quad-Core Exynos 4412, rather than the dual-core Snapdragon S4 (MSM8960) for North American versions of the SGS3. The international version of the HTC One X has the 1.5GHz Tegra 3 vs the North American version which has the S4 as well.
Performance wise, these processors are all pretty on-par. Benchmark scores are close, with the Tegra 3 gaining the upper hand graphics-wise with its 12-core GPU. The processor to look out out of these 3 would be the S4, considering it's the first processor to (kinda) take advantage of the A15 cortex.
...The reason I say kind of, is because there is some discussion on the S4 being a hybrid between the A9 cortex (Tegra 3, Exynos 4) and the beastly A15. Qualcomm is a rebel, and doesn't follow ARM's chip designs like the others do. But I digress...
A15 is going to be a HUGE improvement over A9. HUGE performance gains, higher resolution displays, USB 3.0,OpenGL ES 3.0 (depending on the GPU) and much much more. The dual-core Exynos 5250 is going to be based off the A15 cortex, and it's going to blow even the quad core A9's out of the water. Tegra 4 will almost definitely be based off A15 as well, and it's going to be a sight to see. As for the Snapragon S5, who knows? I'm sure Qualcomm has some cool stuff up it's sleeve.
To answer your question, yes the new Exynos and Tegra processors are going to make older generation processors obsolete, but that doesn't mean you made a bad choice. The SGS3 is a great phone, and as such has tons of developers making custom roms, kernals, and other fun hacks to keep you occupied for the months to come hack away!
hope that helped!
You didn't make a mistake as at present android is not able to push current quadcore devices to their limits and there is a scope for lot more improvement
So even though next gen processors will be lot more powerful, your phone will still be able to handle next android releases so Don't worry and enjoy your S3

Android already has full multi core support. The only thing holding back multi cores is the fact that many apps still don't make use of them.
Also, that other guy made some great points but forgot to mention S4 Pro, which we already know a good deal about and is very impressive. It sets the bar high for the next tegra and for exynos 5250.

They're not going to be "completely obsolete" (even GN and SG2, for example, are still good phones despite being "last year") but there is going to be a large performance increase to A15.
There's always a next big thing coming out, but generally it's not worth waiting for unless you're on the cusp. Even if the generation you shop is relatively old, the competitive market (unlike, say, that of a fruity company) helps to compensate you by providing discounts of the previous tech.
S3, in particular, is a darn good phone no matter how you look at it (except that it has hardware buttons, but I digress..)
as example i take 2 device (but the question are general)
Nexus one: snapdragon S1 QSD8250 at 1GHz with Adreno 200
Galaxy mini 2: snapdragon S1 MSM7227A at 800 MHz with Adreno 200
im noob but i cant see big difference between these 2 devices, just one
Nexus is hold at gingerbread
Galaxy mini 2 is planned to JB (and there is already a custom rom that works very good)
THE QUESTION ARE SIMPLE:
is there a techical reason which prevents the nexus one running JB or is it just marketing?
thanks to anyone who wants to give me a technical explanation
up
I think just marketing because the company want to earn money with new phone so if they say that they will be upgrade a "new phone" peaple would like to buy them. If they say about a old phone it won't be the same.
any tecnical answer ?
up
Don't think there's any technical reason. Devs have come up with CM10 roms for nexus one, so probably manufacturers can provide jb on such phones if they really wish to.
I've got a 4G/LTE Moto G, can I use the ROMs available for the earlier model?
Nope, they won't work... But dont worry, developement is increasing for the 4G model...
Ah, I'm surprised to hear that. Out of interest what makes them incompatible? My naive assumption was that internally the two are basically the same phone.
I am also curious. I suspect no-one has made a serious effort to try. I am experimenting in this area at the moment.
It could be dangerous to flash the non-4G bootloader (motoboot.img) on 4G, but other than that I think it's harmless to try flashing a stock XT1032 Motorola firmware image.
They aren't, it's the chipset that causes issues and lack of compatibility. Two different architectures, means the drivers are different, now could someone make a jumbo rom that offered that option? I don't know, I'm not a developer. I just have advance android hacking knowledge since I hacked all of my devices based off of others works. So while I understand the basics, it doesn't extend that much further. The Wifi tablets are running on Samsung's Exynos CPUs, and the 4G are running on a Qualcomm 805 chip (I think it's 805), so they're structurally quite different. Samsung adheres to ARM standards, where Qualcomm's 805 is Krait based, which is a proprietary layout, unique to them alone. So even if the Qualcomm wasn't 4G and just a regional variant, the roms would be different because the CPUs are so different. Also why Krait chips were kicking the crap out of ARM chips.
With the Nexus 6 announced, I was quite disappointed, as I was expecting Google to release an updated version of Nexus 5, just like they did with Nexus 7 back in 2013. I'm not a fan of phablets, and 6 inches seems too big for a phone, while Nexus 5 sure hit that sweet spot.
So I had this idea - would it be possible to replace the old existing Snapdragon 800 with 801/805? What about the new 808/810 models? Problems that come to my mind are:
Do the newer processors have the same pin layout as the 800 version? I managed to find information that the 801 is, but I'd like to know about 805 or even 808/810.
Do different Snapdragon 8** series processors use the same instruction-set? If not, are the newer versions backwards-compatible with old versions, like for example Intel's x86?
Would the Nexus 5 chipset be able to take advantage of a faster processor? I know ROMs with custom kernels allow overclocking up to 3 GHz, although that's just stupid. With a 805/808/810 though... Would it be as simple as getting for exapmle CyanogenMod, "overclocking" the 805 to 2.7 GHz (what it's actually rated at), and that would be the end of the story? Or am I missing something?
How hard would it be physically to replace the processor? I imagine a skilled engineer with a soldering station would be able to do the job, or are the connections so small that it's practically impossible to do by hand?
How does one obtain a stand-alone Snapdragon processor? I can't seem to find any on Amazon. Do they even sell retail, like Intel/AMD? If not, how do I get hold of one?
What else am I missing? How feasable is this idea really?

while just swapping out the cpu is most likely possible, if not extremely difficult. getting it to run on the nexus 5 would be nearly impossible. where are you going to get the drivers to make everything work? they need to be exactly for the nexus 5 and only for the nexus 5.

Does it need any drivers though? If the processor instruction set doesn't change, I don't see why any software changes would have to be made...
Sorry if I don't understand what I'm talking about, I'm a PC developer and know close to zero about android / snapdragon. I'm just thinking of it as if it was a soldered-in PC cpu with built-in graphics.

of course itll need drivers, its a completely different piece of hardware. youll need drivers for everything.
I think it's safe to say that it will probably never, ever happen.
You can't. It's a SoC meaning the CPU is integrated and can't be replaced
Project ARA will be the first phone able to swap core components
