tegra

long time lurker first time poster.

now, hopefully, the first version of M8 is close to be released. Changing the hardware of M8 is not a question. my question is more about the next version.

as most of you probably know nvidia's tegra processors were announced last june. it seems to gather some steam with opera optimizing the browser for this processor. it performance and low power consumption makes it second to none. i believe it's a game changer and i will most probably wait for a device with tegra processor.

My question is whether JW has any plans to use tegra processors in the next version. it was briefly mentioned in the b-frame discussions, i remember.

No idea, Wong didn't say a thing concerning anything like that. You'll have to wait for the first-gen I think before they'll go into details about the second

Even most first-gen details are still unknown. .

Highly doubtful. Meizu is tightly partnered with Samsung.

DusL, J. Wong did mention the Tegra APX2500 during the b-frame discussions. There was even a poll on the Chinese BBS for the fans to choose whether they wouldn't mind another 3 months of development to change processor, or preferred give up on b-frame hardware support. This was also discussed here at MeizuMe.. you should remember, since you also posted in that thread

Anyway, in the end it was decided that the M8 would keep the 6410 processor to avoid any more delays, and because it was still unclear whether the Tegra itself supported b-frames in hardware. Personally, I'm totally happy with the 6410. It's still one of the most powerful mobile processors out there (along with the Tegra and the OMAP3), and compared with the 6400 used in the iPhone (and originally planned for the M8) it's a real winner.

@chengdude:
IMO, Meizu's history with Samsung is not really a partnership, but more like using their components because that was the most convenient choice. But if the Tegra becomes a real advantage in terms of performance AND cost, I don't see Meizu turning it down.

I post too much

Quite curious about the performance and battery life of the m8. I'm assuming they're running it on the full 633(?) MHz. The iPhone CPU however can run at 620 but is underclocked to something like 415 MHz to conserve energy, and the batterylife is still dead in a day.

Actually, I'm unsure whether JW decided to go with the 633 MHz or with the 800 MHz they mentioned later.. did he ever post a final decision on that? Anyway, the 6410 seems to be more energy efficient than it's predecessor (the iPhone's 6400). What worries me the most on the M8 is actually how much juice will the screen consume.

But I guess we'll have to wait to see how the M8 will perform in the end. Right now we can only speculate. Besides battery life there are still a bunch of other things which are still unclear. For example, will the M8 use 16 bit color or 32bit color after all? And what about the B-frames problem, has a software solution been found?

PS: I also heard about the iPhone being underclocked, but I was under the impression that a later firmware had removed that limitation.. or at least that it could automatically use more power when needed for some functions.

Traps,

The iPhone first ran at 400 Mhz underclocked, which was reset to 415 MHz in a later firmware. So it still runs much slower than usual (which is something like 620 MHz).
Next to the CPU is the screen that uses up a great deal of energy, true. Too bad the Xperia/etc aren't out yet, that could give everyone some indication of what to expect.

The Xperia is out, in the UK anyway. One of our members at dapreview got one.
