The Arm Cortex A9 bench marks were released a while ago. They were all posted on xtremesystems if you want to go digging into that shit.
They had to overclock the CPU for it to beat a two year old Atom chip.

Having the Apple name on your chip isn't particularaly significant if you mean brand power. Having Intel on the other hand...
http://news.softpedia.com/news/ARM-Demos-Browsing-Performance-of-Cortex-A9-131328.shtml
One of the key features of ARM's chip designs is that they provide performance at considerable low power requirements. The side-by-side performance video comparison that the company has posted on its YouTube channel, shows a Cortex A9 development board compared to a 1.6GHz Atom-powered netbook, as far as the browsing performance is concerned. As you can see in the video, the two designs are comparable, in terms of performance, but there are a couple of elements that need to be pointed out.
First of all, the ARM processor is known for its low power requirements, being used in mobile phones for years now. However, another strong point is that, the ARM processor used in the video was clocked at 500MHz, compared to the 1.6GHz speed at which the Atom CPU was running.
Considering its performance potential, these processors could end up in some of the upcoming ultraportable devices, such as tablets or low-power notebooks. There are some reports that indicate Apple will use the Cortex A9 for its much-anticipated iSlate, the company's rumored take at the tablet market.
tino said:This machine has serious problem as a travel companion or multimedia companion.
Let me start with oversea travel companion. Say you want something more convenient than a netbook, you decide to take the iPad with you.
* You have to physically cut the sim card to find out if it's compatible with the iPad. This is kind of decision I just know its Steve Jobs's call and I wish he retire already.
* There is no camera for Skype, which is probably the most important feature in oversea travel
* Again, not IMing and browsing at the same time.
All of these are simple to implement. Apple can even offer its own IM client that work in the background and keep the rest of the third party App singletask. This is how the music player work anyway. Jobs is holding back.
As for serious multimedia companion. It's a great photographer companion if you can get it to read compact flash, which is what the high-end professional DSLR still use today. You have to use a stupid usb cable. It would be great if you can plug in the CF card and show your clients what the pictures look like.
I hope this device kick start the 6-10 inch "smartbook" market that can do more than the iPad. I am sure the WM/Android/Chrome smartbooks and tablets will look uglier than iPad and hey I will take them for professional reasons.

Blackface said:They didn't design the chip they are using now, ARM did. Just like they have been designing chips for small devices for years. Including Microsoft products.
Zaraki_Kenpachi said:But again even if that article were true, which it isn't, it still doesn't mean you're going to have horrible slow down. It's not about raw computing numbers as much as how it's being implemented. Raw numbers always help but it doesn't mean that this will go to hell if they let more than music and mail and stuff run in the background.

PrivateWHudson said:I haven't read through the thread a whole lot, but does the iPad NOT have an SD card reader? It doesn't seem to be a great media device if I can't upload pictures from my camera, or video from my camcorder. If I could use the iPad as a portal of sorts to get media to and from some network attached storage, then it'd would be a perfect media device. It looks more like a pay to play device that's just a portal for iTunes and iBooks or whatever.
avaya said:The point you really have there is cheaper licensing. Tweaking for power and cost can be done by the vendor in almost all cases. Though I would say the cheaper licensing is up for debate since they did not build this from the ground-up, it's still ARM and they are still tied to the ARM roadmap since Apple is not a semiconductor company.
As we move to more powerful mobile devices the edge will shift further and further towards Intel/NV/AMD. It has an air of inevitability about it.
The real reason they did not even consider the Atom right now is very simple and two-fold. Instant backwards compatibility with current platform and stops people from trying to get Windows onto the thing. Very simple reasoning.
There's an adapter, check apple.comPrivateWHudson said:I haven't read through the thread a whole lot, but does the iPad NOT have an SD card reader?

As well as the fact that a single core A9 only consumes 250 milliwatts. A 1.6ghz Atom uses what, 2.5 watts?avaya said:The real reason they did not even consider the Atom right now is very simple and two-fold.

Raistlin said:I'm looking forward to hearing more info on how this all pans out. For the doc connector it claims to be for cameras only. However what would stop you from hooking up and USB mass storage device? Only thing I can think of is that it only allows you to grab pictures and video?
Regardless, it appears you can also set up some sort of shared drive on your PC/Mac. That is what I'm really curious about. Will this only function as a swap space, or can you directly run music, pics, and video through it? That seems pretty cool either way, though obviously the latter would be the best. It's only downfall is what do you do if you're out somewhere and want to copy something? Obviously those drives won't be setup on someone else's computer ... so you're kind of stuck bringing the dongle with you.
Blackface said:All the A4 is is a pretty word for an ARM CPU/GPU combo in a SOC format. We have been talking about the CPU this entire time. The ARM Cortex A9 @ 1ghz. Scroll up if you want to read.
Raistlin said:The only real issue I have with the A4 is that it can't support 1080p which is a bit odd for a media consumer in this day and age.
Granted, it doesn't really matter since the iPad can't even output HD (though obviously that bothers some of us as well).
well, isn't that what i said? no operating system's scheduler does process prioritization, not on a macro level anyway. everything a scheduler does is make sure that the computational resources processes are given correspond to some pre-established picture of priorities, that's all. as such, the question of background/foreground/only-on-weekends/etc is not the scheduler's business. but that does not mean the question does not stand as such - it clearly does in a work-oriented environment.tfur said:I guess it all depends on how you define "background" time. There is no concept of background time in UNIX; there is priority and context switching. There is always something in the run queue, and the concept of background time does not fit into the UNIX infinitely looping scheduler construct.
how many priorities a process/thread can have with a preemptive scheduler does not really solve the fundamental problem of meta-prioritization. the latter concerns the problem of particular work done per unit of time.There are modern UNIX operating systems that do have quite a bit of control for both kernel and user scheduling. Solaris 10 has nearly 200 different priorities for threads, that include "interactive" and "real time" scheduling.
whether the ipad, per se, requires a paradigm shift or not is one thing. but whenever the question of workload efficiency stands, the paradigm gets a shift away from dumb multitasking. there's a reason why many real-time, workload-oriented environments are cooperative-multitasking; with cooperative multitasking the question of work done per unit of time is inherently connected to activity-oriented scheduling - that's what cooperation is. preemptive environments try to mimic activity-oriented scheduling, and often fail. at the end of the day closed, cooperative ecosystems are the most work-efficient thing people have invented so far. this is one of the reason why outer-space exploration robots run cooperative-multitasking RT OSes and not embedded linux, solaris, or any other unix flavor ; )In my opinion, there is nothing that the iPad does that requires a paradigm shift for task scheduling. The only reasons for single tasking at this point are: design choice, and memory constraints.
nobody knows anything yet. the only educated guess one can make at this point is that the A4 is probably an A9 derivative design, largely a responsibility of PA semi.Does anyone know how much memory this device has?
LiveFromKyoto said:It pretty much does 720p: 768 x 1024.
mrkgoo said:I agree that Jobs is holding back the camera and built-in iChat. MAybe intentionally, or maybe just because it's not ready, or they want a feature to introduce later.
LiveFromKyoto said:Two compelling reasons for this -
1. It's generally agreed that you need to be much further back from the screen than you will be with the iPad to appreciate/notice 1080p.
2. iTunes only sells movies in 720p. They don't want to add expense to the display while simultaneously making their download service look bad. Especially for something that nobody but people scouring the spec sheet will really notice anyway.

Zaraki_Kenpachi said:I think he means outputting to a second display such as a tv which it can only do 480p/576p (or whatever it is that europe uses).
mrkgoo said:Oh yeah, since the iPad can output display, you might want to carry around full res versions that play on both it and on an HD display.
Assuming of course that the display output allows movies.

Also, Macrumours reports Apple correcting the promotion ads to show NO FLASH.

:lol.
It's like:
Apple - no flash.
People - hmm. Maybe. I see flash in some promos. Hmm. Maybe.
Apple - NO FLASH.
It's like a firm statement.

Kibbles said:The iPod Touch connect to a TV and play HD movies? I need to know how to do this.
mrkgoo said:Again, correct me if I'm wrong, but I thought the iPod touch couldn't play HD movies. It can output video, however, with the right connection. Not sure what that is anymore. My 1st gen needed the dock with AV output.
mrkgoo said:Well, 'doing' HD is different from displaying it. Hd is defined as 1280x720p. Content like this will have to be scaled to fit on the display. Of course a lot of movies aren't that aspect ratio, but they're still 1280 wide.
Displaying it is not necessarily about appreciating it. If the iPad can play a 1920x1080p video, and you have that level of content, then you don't have to transcode - the device will just play it. Transcoding may be more or less trivial, but since the iPad is a syncing device, it'd be nice not to have to have two copies of files on your computer (one original, one transcoded for the iPad).
For me it's not a big issue, however. I don't have that much 1080p content. For sure, it may be more prevalent (blu-ray rips, or maybe iTunes will upgrade for 1080p sales), but when that day comes, Apple will likely sell an iPad that can do it.

Raistlin said:[Derail]
In the future, I envision this sort of tablet device as having some sort of wireless connection (wireless HDMI, etc), so you can simply transmit photos and movies to a TV, as well as transmit music to a stereo.
Now that would be awesome
[/Derail]
Raistlin said:This part however, I'm disappointed in. While I'm fine with the screen res (though I would have preferred a widescreen aspect ratio - the iPad already has a fairly substantial bezel on it ... when viewing HD material, it's exasperated), the fact it can't output 720p is annoying to me.
Vennt said:Not true unfortunately, 720p is 1280 pixels wide. - Its close, but not strictly HD.
Raistlin said:Well, it doesn't have 1080p res anyway. I simply meant for compatibility, since people don't really want to have a 1080p and 720p version of a file laying around.
When I think about it though, that is coming more from the client/server mentality I have. This device won't be streaming, so as long as iTunes can transcode a 1080p movie when syncing, I'd have no problem with it.
mrkgoo said:There's probably an app for that.
It would be cool if they made home sharing/sharing available on itunes, so you can stream content from your other computer. Or if it could connect directly to Airport express and use Air Tunes.
