Re: Sailfish OS (officially) on Sony Xperia devices
 

Significantly smaller lithography - less power consumption, better efficiency. Two more cores with all the same extensions, higher maximum clock. Significantly larger battery - I already get 4 days to a week on Xperia X. That alone is worth it to me.

Plus, the design of the XA2 is reminiscent of the Nokia N9 - flat top and bottom, rounded corners. At least to me.

Re: Sailfish OS (officially) on Sony Xperia devices
 

Yup, love the design.
Not a good point that the speaker is at the bottom :/

Re: Sailfish OS (officially) on Sony Xperia devices
 

Be careful when comparing the X & XA2 by core number. As you can see:

Xperia X:
Hexa-core (4x1.4 GHz Cortex-A53 & 2x1.8 GHz Cortex-A72)

Xperia XA2:
Octa-core 2.2 GHz Cortex-A53

While XA2 has 8 cores, it's 8 times the simpler less advanced A53 core, while X has a big-little cluster with four simpler A53 cores and two more advanced A72 cores. This could have some advantages in single core performance and also in the rather important "race to idle" (getting task done as soon as possible so that the phone can quickly return to low power states).

On the other hand, it might still not be really noticeable with real world usecases (maybe people already did some comparisons/benchmarks on Android ?). :)

Re: Sailfish OS (officially) on Sony Xperia devices
 

Yet those cores are not faster than those of even the JP1. Not many apps will actually use those eight cores. I have an 1.4GHz quad core tablet (Ubuntu Touch). It uses the same A53 cores. It is slow.

Re: Sailfish OS (officially) on Sony Xperia devices
 

XA2's Snapdragon 630 uses big.LITTLE as well. 4 x 2.2GHz + 4 x 1.8GHz with the 630 vs 6x 1.2GHz + 2x 1.8GHz with the 650. Watching AIDA on various benches on my Xperia X, I rarely ever get the more advanced cores to spin up, so I don't count on them doing a lot.

The lithography and clock speed differences are monumental. At worst, the 630 will be as fast as the 650, but with much less power consumption.

JP1 is a dual core 1.4GHz Krait 300, with really slow (by modern standards) LPDDR2. That's a huge bandwidth and clock/core hit. That's why it's slow.

Re: Sailfish OS (officially) on Sony Xperia devices
 

sure, if we are talking about price. It was just an overpriced midranger. Even X Performance was quite behind other flagships.

Re: Sailfish OS (officially) on Sony Xperia devices
 

That's not what the spec sheet says. big.LITTLE is not just about clock speeds, it's about mixing low-powered and high-powered cores, using them when needed. The 650 does have a big.LITTLE set-up, the 630 hasn't.

My claim is that for most intents and purposes the XA2 isn't (much) faster than the JP1, despite the much newer tech.

From Wikipedia: Cortex A53 scores 2.24 DMIPS/MHz; Krait 300 scores 3.39 DMIPS/MHz. Converted to their maximum frequency on these devices: A53: 4928 DMIPS. Krait 300: 4746 DMIPS. Based on this, the A53 at 2.2GHz is barely 4% faster than a Krait 300 at 1.4GHz.

Sure there are other factors, and yeah the 630 has four times the cores, but I'll kinda doubt you'll notice that when doing some browsing.

Given my experience with a A53-powered device, I'm not too compelled to buy another one.

Re: Sailfish OS (officially) on Sony Xperia devices
 

Maybe ur right but i would like to see a review of testing between those Phones u mentioned and on a different OS , user experience etc.?
Already have an XA2 (waiting for SFOS 3), used xperia x before with sfos and andy. and user experience is totally different even specsheets say otherwise!

Re: Sailfish OS (officially) on Sony Xperia devices
 

All that I can tell is that XA2 is also running really smoothly on Oreo.
I can compare to the X before I switched it to SFOS and we are talking about 2 different experiences.

Re: Sailfish OS (officially) on Sony Xperia devices
 

SONY XPERIA-XA2 is more elegant than X, also more similary to beloved NOKIA-N9

Re: Sailfish OS (officially) on Sony Xperia devices
 

Hello sailors
someone here could connect the sd with ext4 for the sony X.

Re: Sailfish OS (officially) on Sony Xperia devices
 

The 630 is big.LITTLE, two discrete sets of cores, they're just all A53's. Remember, the 650 spec sheet doesn't indicate it's big.LITTLE, either, it just denotes two obviously separate groups - 2x A72 + 4x A53.

"The Snapdragon 630 SoC uses a familiar octa-core Cortex-A53 CPU configuration. Unlike the Snapdragon 625/626 that it replaces, the Snapdragon 630 has a more distinct big.LITTLE arrangement with four A53s running at up to 2.2GHz (the same as the S626) sharing a 1MB L2 cache and four more A53s only reaching up to 1.8GHz and sharing a smaller 512KB L2 cache. While there should not be much difference in CPU performance and power compared to the Snapdragon 626, the Snapdragon 630’s Adreno 508 GPU performs 30% better on average than the S626’s Adreno 506 GPU. It also supports Vulkan and all of the latest 3D graphics APIs at resolutions up to 1920x1200. The Hexagon 642 DSP still supports Qualcomm’s Snapdragon Neural Processing Engine SDK for machine learning and TensorFlow, but does not share the Hexagon Vector eXtensions (HVX) microarchitecture of the more powerful Hexagon 680 and 682 DSPs."


That said though, the A72 cores on my Xperia X rarely ever cycle up under most load conditions and use cases. That indicates that, more often than not, the A53's are doing the bulk of the heavy lifting.

The A53's on the Xperia X are the same clock as the JP1. The Xperia X just has double the cores, much wider bus, much faster RAM.

The 630 is the same comparison. Yeah, you won't notice it just browsing, but you will notice the reduced power consumption, newer technologies (like Vulkan support in the 630), bigger battery and reduced heat. That's the point. I'm not saying it'll be like going from an AMD Duron to a Threadripper. I'm saying the power consumption reduction granted by the newer fab, the newer technology potential (faster eMMC, etc.) makes it attractive.

snapdragon 400 = 533MHz RAM
snapdragon 650 = 933MHz RAM, big.LITTLE
snapdragon 630 = 1333MHz RAM, big.LITTLE, hugely better GPU and better LTE modem, 14nm fab

I mean, I get it, on paper it looks like the same tech. It isn't. There are many more factors than just A53 cores.

Edit: some synthetics:

geekbench 4.1/4.2, 64-bit multicore:

snapdragon 650: 2869
snapdragon 630: 4170


kraken 1.1:

snapdragon 650: 3555
snapdragon 630: 9584

Re: Sailfish OS (officially) on Sony Xperia devices
 

Yeah I thought so too! I feel like the XA2 was chosen specifically for that appearance... kind of a nod to times of old.

Re: Sailfish OS (officially) on Sony Xperia devices
 

These are not the tests. Give me a linux kernel compilation time on both, then we'll talk (I'm not asking for SPEC :) ).
Also XA2 is 1mm wider than X (and X is already too big) - speaking of N9 resemblance...

PS Sony and Jolla: xz2 compact, please?

Re: Sailfish OS (officially) on Sony Xperia devices
 

Thanks, I stand corrected.

I do find those benchmarks indicative for the actual problem: the A53-cores. The Kraken benchmark runs about 3 times slower on the 630 than on the 650, indicating that web browsing is severely hampered by these cores. And given that browsers still aren't all that multithreaded, more cores won't help.

I ran Kraken on my JP1. Obviously I don't have Chrome, so direct comparison to the numbers you provided is not really possible. (Although, on my desktop, Chromium and Firefox are 1053ms and 908ms, so not that far apart)

Firefox 60.0.2 (Via AlienDalvik): 14553ms
SFOS Browser 2.2.0.29: 12464ms (a bit faster, I didn't expect that)

Could someone with a Xpera X or XA2 run these benchmarks on Firefox as well? Then that might be a better comparison.

[edit] Yeah I get it, the XA2/630 while not much faster, is much more efficient. And overall the XA2 will be a big step up coming from the JP1. Even physically, I've had one in my hands, it is a nice device. But speed, apart from games and some edge cases, isn't part of the upgrade.

Re: Sailfish OS (officially) on Sony Xperia devices
 

Some Kraken 1.1 benchmarks of my two Jollas and Nokia 6 and Alcatel Pixi 4 Android phones:

XperiaX (2.2.0.29):
- SFOS Browser: 6127ms
- Firefox 61.0 beta (Aliendalvik): 6345ms

Moto G4 plus (snapdragon 617, 4xCortex-A53@1.5GHz, 4xCortex-A53@1.2GHz, 2.2.0.29):
- SFOS Browser:11155ms
- Webpirate: 23212
- Webcat: 23267

Nokia 6 (Snapdragon 430, 8xCortex-A53@1.4GHz, Android 8.1.0):
- Brave: 13492
- Chrome: 13480

Alcatel Pixi 4 (6") (Snapdragon 210, 4xCortex-A7@1.1GHz, Android 6.0.1):
- Chrome: 21619ms

Re: Sailfish OS (officially) on Sony Xperia devices
 

Okay, I must say, that's faster than what I'd expected. Extrapolating to 2.2GHz of a XA2 that would mean 7605ms, 1.7 times as fast as on JP1, and not even that much slower than the X.

Re: Sailfish OS (officially) on Sony Xperia devices
 

I reran the benchmark and got almost the same result... It should be accurate.

For kicks and giggles I also tested our slowest device: Alcatel Pixi 4 (6"). It has Snapdragon 210 (4xCortex-A7@1.1GHz):
- Chrome: 21619ms

Re: Sailfish OS (officially) on Sony Xperia devices
 

Just for the record (again :D): if you don't see the bigger cores used often in Aida on Xperia X with Sailfish OS - you are actually just seeing the still sub-optimal core scheduling. From Sailfish OS 2.2 release notes:

I guess this would be FIXED in XA2 if all the cores are very similar. ;)

Re: Sailfish OS (officially) on Sony Xperia devices
 

Just for the records:

Re: Sailfish OS (officially) on Sony Xperia devices
 

I guess it depends on the region...
Our local operator lists the following 4G frequencies(MHz): 800/ 850/ 900/ 1800/ 1900/ 2100/ 2600
Source (in estonian)

However, when you compare the phones, you'll see that Xperia X is in many characteristics more "high tech" than Xperia XA2:
GSMArena comparison

Re: Sailfish OS (officially) on Sony Xperia devices
 

Xperia X just have two versions... Single and double sim... Xperia XA2 have various versions for differents regions... I have the USA/Canada/Latin American version that have differents frequencies that you listed (as for example band 4 (1700/2100/ that use my operator for LTE in my country). Apart of that, I think that nothing more varies from the European version

Re: Sailfish OS (officially) on Sony Xperia devices
 

It's probably locked, so you won't be able to install SFOS.

Re: Sailfish OS (officially) on Sony Xperia devices
 

Nop ( 10 chars)

Re: Sailfish OS (officially) on Sony Xperia devices
 

well then you might wanna hurry, cause everywhere else it's price is ~$300.

Re: Sailfish OS (officially) on Sony Xperia devices
 

Already bought one :D

Re: Sailfish OS (officially) on Sony Xperia devices
 

Thanks for the head up.

Got one also :)

Re: Sailfish OS (officially) on Sony Xperia devices
 

i dont speak french, but I suppose this is some local offer as it tries to push me to buy some mobile service with data plan

Re: Sailfish OS (officially) on Sony Xperia devices
 

It's probably only for french resident, for sure.
Regarding the service linked, you can take the 5€ per month and cancel it as soon as the phone arrived ;)
Just ordered a 2nd one ATM, so if anyone is interested for my first phone @200€ :) ( mono sim )

Re: Sailfish OS (officially) on Sony Xperia devices
 

I really hope that XA2 ultra will be supported. Don't give a $#&%/ about front camera and AFAIK that's the only difference.

Re: Sailfish OS (officially) on Sony Xperia devices
 

Minutes from last meeting suggest that SFOS3 on X will stay on 3.10 kernel (with possible rebase later), while XA2 will get 4.4.

Re: Sailfish OS (officially) on Sony Xperia devices
 

Anyone notice higher power consumption on 2.2.0.29 on Xperia X?

Normally it takes a few days to settle (reindexing and whatnot) after an update, and the battery is back to normal. But this time it doesn't seem to last anywhere near as long as before.

I may reflash and see if it fixes it, but right now it's not looking good. I'd kill for a custom kernel that I could undervolt with...

Re: Sailfish OS (officially) on Sony Xperia devices
 

my phone is experimenting the same issue on battery consumption, not sure what it is. on my test look like vpn or patchmanager-III

Re: Sailfish OS (officially) on Sony Xperia devices
 

I don't think so, at least it does not feel like it would be running down any faster than before.
I have constant power logging on, so if I have time I could try to draw up some graphs on average power consumption of it before and after the update.

Re: Sailfish OS (officially) on Sony Xperia devices
 

Only 1 model of XA2 is chosen as Jolla said, and I cant buy that model in my country that it is european version...

Re: Sailfish OS (officially) on Sony Xperia devices
 

It'll probably be the same compatibility as with X, firstly the single sim, then the dual sim later.

Re: Sailfish OS (officially) on Sony Xperia devices
 

The X license was supposed to be sold in Europe only. I wouldn't be surprised if they only support European models.

Re: Sailfish OS (officially) on Sony Xperia devices
 

Thanks juiceme! Only if you have time, it's not that important.
