iPad 2 news, new?

[Brian8bit]

Nice.

Get over it.

The device that isn't even out yet? I have. It uses the same Cortex A9-based, dual-core 1GHz CPU that will probably end up in the iPad in 2011. Oh, and notice how they haven't published the battery details. Apple publishes 10hrs, and most reviews are finding that to hold water.

Probably end up in the iPad. Maybe then I'll get one. As for battery saving, I suggest you look into Qualcomms power saving features for their dual core Snapdragons. Like I mentioned already.

I get that, but really you've invented a problem that doesn't exist and now have crazy discrimination for all single core products because of it

The problem does exist. But people don't know any better because they've only used single core ARM so far. And you're right. I hate single core. Like I've stated time and time again. Because they're horribly, painfully ****. Like I've said already.

Instead of picking fault with the sources I posted, why not post your own?

Because there is very few (hardly any) sources comparing single core and dual core ARM chips as they're so new. Any sources commenting about how good the Apple A4 is, are old. And they haven't tested it against dual cores. Of course they're going to be happy with how it performs. It's all they had. They don't know any better. Like I said. Already.

Here's a post from PCMag, any others you're happy aren't biased?

The bits you've highlighted I've already commented on. Repeatedly. I've already said the A4 is superior to the single core snapdragon ARM. That it is the best of a bad bunch. The second highlighted bit is opinion. And like I've said already I found any smartphone I've used so far leaving me unimpressed. You haven't. We have different standards.

Now can we stop going in circles? Because I'm pretty sure whatever you retort with, my retort is going to contain the exact same opinions as the last several times. Again.

Which tasks do you find the experience using iPhone/iPad to be poor performance wise? I have an iPhone 4 and while the CPU isn't clocked as fast as the iPad I find it runs great, I never notice any slowness like I did with the iPhone 3G.

Hyperbole means nothing to me. The proof is in the pudding. Until the Qualcomms come out, with improvements to speed while maintaining battery life, I couldn't care what they promise. Case in point; The Pentium P4 was meant to be the muts nuts, and the thing ran hotter than hell.

Single core CPUs, on a stripped down OS are fine. The problem does not exist, or we'd have seen the initial reviews claim the devices were sluggish or there would be hundreds of posts across various forums saying how slow the iPad is.

Because there is very few (hardly any) sources comparing single core and dual core ARM chips as they're so new. Any sources commenting about how good the Apple A4 is, are old. And they haven't tested it against dual cores. Of course they're going to be happy with how it performs. It's all they had. They don't know any better. Like I said. Already.

Yes. But as I have already stated. At no point did the original reviewers say the device needed another core, or that it was sluggish.

They will do a speed comparison with the next dual core iPad comes out. I hope they prove that the difference isn't light and day, so you shut up.

The bits you've highlighted I've already commented on. Repeatedly. I've already said the A4 is superior to the single core ARM. That it is the best of a bad bunch. The second highlighted bit is opinion. And like I've said already I found any smartphone I've used so far leaving me unimpressed. You haven't. We have different standards.

For all intents and purposes, the Apple A4 IS an ARM Cortex A8.

The second bit, the bit referring to how snappy the device is? Yes, that's opinion. A widely regarded opinion that the CPU in the iPad is fine (see: my entire point).

Now can we stop going in circles? Because I'm pretty sure whatever you retort with, my retort is going to contain the exact same opinions as the last several times. Again.

You lost this argument by spouting biased crap. Then repeating it, stating your opinion as fact.

Multi-core ARM CPUs will be a major boost to mobile devices. Yes, they're more powerful but they also deliver greater power efficiency.

Who doesn't want a mobile device with more power and better battery life?

 

[Deleted member 651465]

Exactly, but you cannot call the iPad a slouch.

I'll welcome a dual core model, if the battery life remains 10hrs, but don't imagine it'll be noticeably quicker unless true multitasking is implemented

 

[cu3ed]

You're right. I completely forgot about the magic and fairy dust.

Thats the best you have, really?

Apple deveop the hardware first hand...the are even more involed in developing the Software first hand.

Big hardware only is their because Hardware companies, that have no involment what so ever with the software side of things, have to cover every possibility.

Or jsut for sales for poeple that like big number over other number, without actually really knowing what real world improvment that is over the other.

 

[Spit]

Totally agree with you EVH.

Brian8bit will just want a triple core cpu when the dual cores come out and will be shouting around that dual cores are rubbish!

We all have annoying friends like him who when you get something they like to tell you they are waiting for the unreleased model and in reality never ever end up buying anything.

Whats betting that he still has the 8bit machine he has in his title and says the mouse is dead and is waiting for true voice control

Well:

Battery capacity
- More RAM adds higher power requirement
- More cores adds higher power requirement
- Faster CPU/memory subsystem adds higher power requirement
- More devices (camera etc) adds higher power requirement
- retina resolution screen adds higher power requirement
=
Battery life equal to the iPad1 or better

Now balance that simple equation.

It depends on the efficiency of the next generation ARM chips, the efficiency of the batteries (after all it's not going to have more space).

The dual core will make next to no difference when its released. Just like in the Consumer PC market all those years ago. It made 5% difference at best, it was just about epeen (just like 6/8 core is now).

iOS does not multi task, the built in iOS back ground services use hardly any resources.

All new apps need to be built around the old devices first as that's what most people have. i.e. single core, 256mb ram. You wont make any money otherwise.

Have you played rage?

The new Qualcom chips are not shipping in the quantities that Samsung, HTC etc need.

The playbook is not yet released and the only things on the tube are well rehearsed and its UI is choppy as well, that would drive me insane overnight.

 

[Kainz]

pmsl @ dual core comments. Reminds me of a poster on macrumours who repeatedly slates the ipad for not being dual core, or having 1gb of ram. Yes because a dual core will INSTANTLY speed up the OS and apps...

Leave it go now, brian8bits already had a holiday for his outburst

 

[mast3r]

wowie! allready.

- More cores adds higher power requirement

That's not true for mobile devices in general. I attended a talk by an ARM engineer 2-3 years back and his main argument for using multi-core CPUs was power management.

The quicker a mobile device can execute a command, the longer it can spend asleep. Also, it can dynamically shut down entire cores based on load.

And let's remember that the iPad already supports true multitasking. It just isn't available for by 3rd party applications.

A sensible post, thread saved

There's also some rumours about the USB/mini-USB port on ipad2. I can only believe this is slightly true due to new EU laws on charging sockets.

 

[theheyes]

I'd really like a USB port on an iPad as long as it's not some hobbled implementation.

 

[Feek]

Never needed a USB port on my iPad and don't care about it.

True, an instruction can be executed more efficiently to take less power. Cores already have dynamic power saving.

It comes down to the customer expectation:
1. It drives up the expectation of the customer that they can do more in the background (developers inflate as they believe their app is the only thing running too).
2. Up goes the pressure for full multi-tasking (even when 'sleeping').
3. Up goes the RAM and storage requirements.
4. Up goes the power requirements at a faster rate than the battery technology allows.
The result then appears as either bad battery life and then gives designers a headache attempting to fit be battery capacity in which in turn leads to bulky and unattractive designs. (Third option is to ham-string the system to keep the power requirements in check)

I think we, OcUK members, have a very technical slant to discussions and probably represent a 1% of the iPhone/iPad users. The other 99% want something that fits their expectation - sleek, nimble and light.
Given the financial and experience-centric evaluation (given the battery life and current technology) result in a backward pressure against ideas such as multi-core for the reasons above.

If it was added then it is likely to be severely restricted to save power.
