[Q] Advice before jumping on development - General Questions and Answers

I'm going to buy a phone from a lesser known brand, and will be developing custom roms for it
The specs are as follows
CPU: 1Ghz Scorpion Qualcomm
GPU: Adreno 200
RAM: 256 mb
Chipset: MSM7627a
Display: 4inch. 480x800
Dual sim
Coming from a samsung device i always had ODIN to protect my back
and since this a small brand i doubt i will be able to get my hands on some equivalent
so my question is
Is there a way to get back to the stock rom after i potentially brick (soft-brick) the device?
will the HTC based hBoot method work?
since the nexus one and incredible s share he same CPU-GPU-Res combo
Thanks

Qualcomm's Dual-core cpu inferior to others?

So I visited www.phonearena.com yesterday and saw the news about the HTC Pyramid.At first I thought wow,Qualcomm and HTC won't only get left behind but will have about the same technology and will run at higher frequencies.
But then I remembered something that troubled me.I remember reading somewhere that Qualcomm's dual-core CPUs will be based on the current-gen Cortex-A8 by ARM,while others,like Samsung's Orion,will be using the next-gen Cortex-A9 that is superior in both perfrormance and consumption,while being designed especially for dual-core CPUs,unlike the A8.
What's your take on this guys?
No one?

Strongly agree
i hope this isn't true. tegra 2 outperformed old cpu's with only one core running! that's because it's Cortex-A9. now, if it was Cortex-A8, i don't think there would be much of a difference.
In fact i think it is superior to the tegra 2 or Orion plat form despite being an cortex A8 architecture, but it is not a long term solution point proven as Qualcomm is developing it A9 counterpart the MSM 89xx
How it is superior? Well between A8 and A9 architecture to my knowledge there isn't much of a difference, the major one is enhanced soc and the capability to use DDR3 ram instead of being limited to ddr2
But how these two doesn't matter in the short term, well the first one is obvious because Qualcomm doesn't use just a Normal Cortex A8 architecture ( was used on the first gen of snapdragon) as the second generation MSM8255 used on the desire HD for exemple has an enhanced soc and cach point proven when compared to a lets say Omap 3 or hummingbird in every cpu benchmark i believe the MSM comes on top(correct me if i m wrong).
The second point which is about Ram, i don't believe we will be seeing DDR3 ram on smartphone anytime soon so at this it is a kinda useless advantage.
Now add to that if the rumors are correct that one cpu can be switched off if the charge is low then while the on tegra 2 which use a dual core architecture and not a dual cpu architecture.
Edit: this is true + Asynchronis clocking for each core!
Also in terms of graphics, the MSM8x60 comes with adreno 220 which is definitly faster than the adreno 205 almost as fast as the SGX540 and which is rumored to be faster than the GPU in tegra 2, the geforce, as for the Orion is believed to get the SGX543mp2 but Orion is not coming anytime soon, and probably will hit the market once tegra3 and MSM89XX is almost there (which comes with Adreno 300)
Hopefully this does help you, i know that not everything i mentioned is accurate, but i ll invite you to watch this

Synthetic benchmarks like that though don't gauge real life performance though.

I do agree with you, but they do give a scal for the performance especially when there are different types that relies on a different system to test the perfomance.
In real world you have to agree that MSM8255 is the fastest CPU out there atm just look at how the Desire HD is a screamer! or even the G2/Desire Z with the same CPU but clocked 800mhz does a pretty great job even compared to the latest omap3/hummingbird phones.
Definitely, the MSM8255 45nm matches the old MSM8250 65nm even when the stock clock in the Z/G2 is only 800 mhz, versus that extra 200 mhz. The gpu is lacking compared to others.

No,the GPU of the Desire Z/HD only lacks against the SGX540 of the Galaxy S!

As lotis said the only GPU that is faster than the Adreno 205 is the SGX540 and by a very slight marging in 3D while the Adreno wins in terms of 2D. The thing with Adreno GPUs is that they are clocked with the CPU and i believe the comparaisons were done with a G2 vs SGS + lagfix and froyo , i believe the GPU on the Desire HD does have a higher clock than the one on the G2 and thus perform better but again is this a fact or just another rumor if someone could confirm this..
But for a fact we all know that a stock G2 on pure android does 1600-1800 Quadrant score and a pure desire HD does a 1900-2100 on Android + sense out of the box

i m looking forward to the pyramid hopefully HTC will show it on the MWC (but im afraid there is a chance that they won't because they've just released the desire HD counter part in the US aka thunderbolt and inspire 4G) or else i might be tempted by the Motorola Atrix
whats up with all the fear and worries ? quandrant for tegra2 is a mere 1911 . it will get its a** kicked by anthing qcom makes in 2011 .
that said , there is a low possibility quandrant only runs single core enabled on quadrant , but what makes u sure that other apps will run dual core then ?

Nothing!That's the thing!
At the moment there is no software that takes advantage of both cores.I think that Gingerbread also has problems.So we have yet to see the performance gains by dual-cores.

I hope you're right!!
I didn't think it was possible for an A8 to be dual core
The dual core cortex a8 qualcomm is building is a heavily customized version. It has features from a9 built into the cpu.

hey what do you say about the net quad core processors from nvidia.. ? smart phones will become computers and our laptops will be just a notebook..for music and bigger games

My laptop already is for surfing the net only because I prefer the large keyboard(it's a 17 incher after all ).Everything else I do with my smartphone,which has a 25% share of my gaming time.I also have a ps3!
Now,quad-core CPUs will first be for tablets(August 2011) and then for smartphones(Fall 2011?Maybe).These will pack some things like 12-core GPUs etc.Tests have already shown that they beat many dual-core x86 CPUs.What's next?Dunno,but I surely wanna see!
The next computers is possible, but relatively weak computers per say. But can any of our phones run crysis or crysis 2? Are they even remotely capable of generating over 10fps of it? Even the MALI 400MP, Tegra 2, adreno 220 or power vr SGX543 can't manage that. I don't think we'll be seeing any SoC's with that sort of power until maybe two years?
Point being, phones will never hold the same amount of power a computer can output. So computers will stay. Who's to say computer SoC's haven't been improving? sandybridge, quantum processing, six cores core i9, 48 cores? No one cares for computer news anymore?
Anyways onto the topic, looking at the new gpu benchmarks posted of the dual core snapdragon, 1.5ghz. They're making the other cpu's look bad. So maybe the SoC isn't that bad after all. looks like it was a prototype also so the finished product could be even better. Source:

[Q] Porting CyanogenMod 7 ?

We love CM7 and want to see it in Desire S.
Desire S and Desire HD are both hardware basically same. Can we port CM7 from Desire HD to Desire s ? i dont think its very hard to get it working.
Hardware:
Desire S: 1 GHz Scorpion processor, Adreno 205 GPU, Qualcomm MSM8255 Snapdragon
1.1 GB ROM, 768 MB RAM
Desire HD: 1 GHz Scorpion processor, Adreno 205 GPU, Qualcomm MSM8255 Snapdragon
1.5 GB ROM, 768 MB RAM
it would very cool if anyone port it to desire s. i hope i am not the only one loving Cm7 rom.
(sorry for my poor english)
Good luck if you want to, Desire S has a locked bootloader so therefore it's gonna take someone who has the phone and has experience in Android ROMs to be able to port it.

Processors?

Can htc implement a samsung exynos processor in their phones?
T-Mobile G2 1.42 GHZ
The processor is seriously powerful take a look at the amazing power of the latest samsung processor
http://www.youtube.com/watch?v=kwuo5p0AlqU&feature=youtube_gdata_player
T-Mobile G2 1.42 GHZ
They would have to buy and license them out from Samsung, but HTC probably already has deals and discounts with Qualcomm seeing that their phones are based on Qualcomm SoC's.
In all technical terms, can they use Samsung SoCs? Yes.
Now in real world situations, will they use Samsung SoCs? Most likely no.
HTC is a long time Qualcomm partner. Don't be expecting an HTC phone with a samsung processor. The qualcomm/HTC trend isn't going anywhere soon.

, htc really needs to step their game up with processors, obviously qualcome is behind on that aspect, adreno 205 was very competitive to the samsung hummingbird processor having a better cpu, however the new dualcore adreno 220 (if I'm not mistaken) does not stand a chance against the new exynos processor where the gpu is amazing and so is the cpu, if you compare benchmark the exynos 1.2ghz dual core scores 3300+ stock out of the box yet the htc qualcome 1.2ghz dual core scores 2000+ out of the box stock. So when you think about it qualcome hasn't done much of improvement on their new processor the mytouch 4G is a single core and scores 2000+ too. Benchmarks may not be everything but they do give you an idea. Bottom line is htc needs better specs for the tough competition, I really dislike tremendously samsung phone designs and would never switch to their phones no matter what processor they use.

[Q] Processor for Sensation

I just want to ask a simple question, which is the processor for the Z710e:
MSM 8260 1.2GHz dual core
or
MSM 8660 1.5GHz dual core???
I'm a bit confused because the Android Revolution ROM changed the processor data in the about phone into 86660...
MSM 8260 underclocked to 1.2GHz
So, the processor is MSM 8260 which is supposed to be clocked at 1.5GHz??
1.5GHz is the nativ speed but HTC underclocked it for the Sensation - probably knowing they could use the same chip in another model in the future
So if i got this right, the sensation XE and the sensation have the exact same processesor?
They do indeed, exact same everything if you believe this site:
http://www.theandroidsoul.com/htc-sensation-xe-coming-to-o2-uk/
HTC Sensation XE Specifications:
• Dual-core 1.5 GHz processor, Adreno 220 GPU, Qualcomm MSM 8260 Snapdragon
• 4 GB internal memory(1 GB user available), 768 MB RAM (1 GB would have been sweeter)
• 4.3 inch LCD display with gyro-sensor, accelerometer and HTC Sense UI
• 8 MP, 3264×2448 pixels, autofocus, dual-LED flash with 1080p video recording
• Android 2.3.4 Gingerbread O.S
• Expected to launch in Q4

[Q] Which phone performs better: Galaxy Nexus vs HTC Rezound

I am trying to make a decision today since the release of the Samsung Galaxy Nexus was rumored to be pushed back until December and HTC Rezound was in fact released today.
Anyhow, I want to choose the phone based of pure performance disregarding the operating system (Galaxy Nexus is the first Android 4.0 phone). Also, many people prefer the Nexus and answers unfortunately become biased. Please try to have unbiased responses. =]
Samsung Galaxy Nexus
CPU: TI OMAP 4460 dual-core (under) clocked at 1.2GHz
GPU: Mali400MP
HTC Rezound:
CPU: S3 Qualcomm MSM8660 dual-core clocked at 1.5 GHz
GPU: Adreno 220
I have been looking up multiple comparisons but all are inconsistent with each other.
long story short, the G-nex will perform better.
