Exactly, I ran that already but is:

Qualcomm SDM630 Snapdragon 630 (Xperia XA2) better than Qualcomm MSM8956 Snapdragon 650 (Xperia X)?

and Adreno 508 (Xperia XA2) better than the Adreno 510 (Xperia X) ?

Adreno 508 has 96 GPU ALUs at 850 Mhz, Adreno 510 128 ALUs at 600 Mhz. Multiplied clockwise the 508 has a small advantage but maybe it can't keep this higher clock permanently or RAM ist not fast enought so it says 170 GFLOPS for the Adreno 508 vs. 180 GFLOPS for Adreno 510.

I think Qualcomm ist right with the naming 508/510 as practically both GPUs are in same range.

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

It seems the 630 might be as good as the 650, but with much less power consumption and better LTE/Bt/Etc support and the 14mm construction which helps speeding things up whilst consuming less

The 650 still has superior single-thread performance as Cortex-A72 is much faster than Cortex-A53 even with lower clock frequency as it has more than 2x integer instructions per MHz compared to Cortex-A53 (4.72 DMIPS vs. 2.24 DMIPS).

https://en.wikipedia.org/wiki/Compar..._ARMv8-A_cores

Also Snapdragon 630 is 4x 2.2 GHz + 4x 1.8 GHz Cortex-A53 so only the 4 faster Cortex-A53 cores at 2.2 GHz compete against 2 ultra-fast Cortex-A72 cores of the Snapdragon 650 only at 1.8 Ghz working as two big.LITTLE clusters and not as a "real" octacore.

https://en.wikipedia.org/wiki/Big.LITTLE

Yes, the Snapdragon 630 is the more modern chip from a newer generation (14nm, DDR4 RAM, LTE Cat 12/13, BT 5.0, USB 3.1) compared to the 3 year old Snapdragon 650 (once called Snapdragon 620 :) but performance-wise I wouldn't expect more.

https://en.wikipedia.org/wiki/List_o...0,_652_and_653
https://en.wikipedia.org/wiki/List_o...0,_636_and_660

But less power consumption for a similar performance seems to be true:

> Battery life
> Xperia XA2 92h endurance rating
> Xperia X 67h endurance rating (2620 mAh)

PS: Sorry, it's mostly only because of battery capacity increase: :(

> Xperia XA2 Non-removable Li-Ion 3300 mAh battery
> Xperia X Non-removable Li-Ion 2620 mAh battery

Re: MWC2018 news

Here is an interesting Engadget article about Jolla from MWC.

They even mention Dave999 :D

Quote:

Jolla had some profitable months last year and started issuing refunds to people who backed its tablet on Indiegogo. The company won't say how many are left, however. "It's not that many," Pienimäki claims. "Some of them are a bit noisy, but it's not really that many anymore."

Re: MWC2018 news

Sorta glad that Engadget picked up a Jolla story. I'm just hoping for an announcement from somebody that will support the North American region for LTE, whatnot.

Or the mere mention of a tablet... that did get my attention as well.

Re: MWC2018 news

Seriously, why does people here still going in their underpants when the see a Nokia like phone!?

Nostalgia mostly.

Listening carefully to @sailfishos video of Alexey Kogan talking about Sailfish, I think he says that they are due to release another device, possibly for worldwide sales,

Two points worries me quite a bit:

Quote:

Jolla's pitch was simple: If you license Sailfish, you get full access to the source code. ... "That really sets us apart from everybody else," Pienimäki said. Sailfish OS, the company hoped, would become synonymous with security.

So when sharing source codes with selected 3rd party you'll enable them to explore new backdoors and make custom compiled version with added backdoors.

Also since the parts in question are closed source the public won't be able so spot differences in custom vs. vanilla Sailfish parts or search for backdoors themselves.

How can this be labelled as secure?

Not to mention the risk of a total source code leak which would destroy Jolla's business opportunities.

And:

Quote:

Since then, Jolla has inked deals in China -- a country that, like Russia, has a difficult relationship with Google -- and Latin America. In practice, it works a little something like this: Jolla will issue its source code to local partners who liaise with enterprise customers and provide the final hardware. Clients will request services, or features, that Jolla then solves with tools, or "enablers," in Sailfish OS. It could be a mobile device management framework, or an open VPN solution -- mundane features to the average consumer, but critical for secure business communications.

"A good example is security algorithms," Pienimäki said. "We don't do security algorithms for our clients, because typically they want to use their local partners to harden some communication systems. So something like that, in the platform, we'll only do enablers and tell them that, 'Okay here is an API and here you can put your local security algorithm.'"

So basically Jolla is allowing foreign agencies to destroy the security of SailfishOS while looking the other way in the hope of a strong partnership?

Again: Secure?

Please note that I'm really big fan of SailfishOS. I just (like many others fans) see the security aspect as a key feature of SailfishOS which shoundn't be destroyed in the hunt for new partnerships.

Re: MWC2018 news

so.... what's the problem here? The same way any of those 3rd party vendors can implement something, Jolla can also. How do you know that they already don't have a back door since OMG :eek::eek::eek::eek: sailfish is not fully open sourced. Maybe it would be better if sailfish would be fully closed so no one could implement anything :rolleyes:

Re: MWC2018 news

It work like this according to this old image https://pbs.twimg.com/media/Cylz-a0WQAAzJ6i.jpg

So Jolla will oversee any code going back in to SailfishOS to maintain independent offering. Leaking code is probably prohibited by commercial contracts.
