    This is all over the net. Do people here believe it?

    would not be surprised as the OMAP Cpu runs circles around every current snapdragon and dont even get me started on the GPU, its not even close.

    If it was true, HP would have said so prior to the release the Touchpad.

    Absolutely false, according to Rod Whitby. I'll believe him over a stupid tech tabloid.

    No they wouldn't. The claim is it runs twice as fast ON an iPad, not that it runs twice as fast AS an iPad. Why would HP basically say their product runs better on their competitors equipment?


    That said, I am also skeptical of the claim, or at minimum, there are some details missing.

    who care. I am waiting for TP price drop to $100. I don't care TP runs slower than iPad. At $100, it will be really nice web browser.

    The 2 CPU's have the same DMIPS ratings, and the Touchpad has twice the RAM.

    The only thing that could possibly be twice as fast is ipad2's GPU.

    So unless they are talking exclusively about 3D gaming, the whole article is garbage.

    It's hard to say what's "garbage" and what's not, especially after many claimed the whole Best Buy fiasco the other day was "garbage".

    That has nothing to do with a technical argument.

    Feel free to write your rebuttal.

    I'm not giving credence to the technical aspects of the story — I don't know whether that's actually true, or not, and could not care less — but rather the fact that someone on the webOS team loaded up webOS on an iPad .. that doesn't seem so outlandish to think, no less than Best Buy requesting HP to take back 250k Touchpads two days ago.

    I am sure this is BS, BUT if it is true, I want to know how the hell they got WebOS on the IPad to begin with. Without even hints of that detail, I am sure it must be BS. With the hardware of WebOS going away, I would not hesistate for an instant to buy an IPad and put WebOS on it.

    WebOS' javascript performance is twice as slow as EVERYBODY ELSE --- and I think that's what the article is talking about.

    HTML5 on the HP TouchPad Found Lacking, What App Developers Should Know : allWebOS

    I don't think that they have spare engineers to put webos on ipad2 --- when they were straining for manpower to deliver the Touchpad on time.

    It's pretty clear they meant Enyo ran twice as fast on an iPad, which is absolutely believable, and is probably being generous to the TouchPad. iPad has fully implemented hardware acceleration; only thing on TouchPad that is accelerated is translate3d, and even that is buggy and slow if you start talking about alpha blending.

    webOS 3.0 IS NOT CAPABLE OF RUNNING ON ANYTHING EXCEPT SNAPDRAGON. This is from Todd Bradley. This is a completely fabricated piece of news not worth mentioning.

    2nd generation snapdragon is much better than 1st generation snapdragon and a 1.2 GHz processor should be easily on par with a 1 GHz cortex a9 processor. Adreno 220 is also on par with sgx 540 which is in the Ti chip.

    there is no way that a webOS port on a9 would have had twice the performance.

    No. The Scorpion on the Touchpad isn't as fast as the Cortex A9 on the iPad 2. The Scorpion is a glorified Cortex A8 (for instance, it still is in-order). The Adreno 220 is nowhere near the iPad SGX 543MP2. Although not twice as fast, the internal hardware on the iPad 2 is definitively superior.

    About Bradley, I don't know. I've seen WebOS running on non-Qualcomm processors, perhaps this is a limitation of WebOS 3.x. Anyway "twice as fast" seems impossible to me, WebOS speed problem is because of software not hardware.

    it is not a glorified cortex a8 it has limited out of order execution support and the pipeline is different, it also adds full neon support. In actual usage 1.2 GHz snapdragon is on par with 1 GHz ti omap4430 and tegra2. On graphics front adreno 220 is on par with sgx540 but only about half as fast as the ipad2 chip.

    I agree that over all ipad2 hardware is superior. However, webOS is not fully hardware accelerated and thus a port of webOS would not be able to take advantage of better hardware either.

    I know I just posed this, but there is a difference between Enyo, which will run twice (or more) as fast on the iPad as on the TouchPad and WebOS, which is hampered by not having a hardware accelerated rendering engine (along with many other problems, including some memory issues). It is clear the article is talking about Enyo.

    No. It's still in-order execution with a limited support for reordering. It's still dual-issue. Those two things you mentioned are literally the only two worthy improvements, it's fully pipelined and has a Neon 128-bits, and it has only 512 KB of L2 chace.

    Mhz per Mhz I highly doubt the Scorpion performs faster than the Cortex A8, the great improvement, as far as I'm able to see, it's the much improved power consumption.

    What would it take to port WebOS to run on an IPad or Galaxy Tab? (if the code was made available)?
    Is the code in layers so one could only rebuild the underlaying code?
