    Yes BUT it really depends on how much multitasking you have on actually! If the system keeps limboing between these cores (Power->lowpower->power->lowpower) I guess it really makes no sense but if you only keep one application running then it would make sense.... But thats not what fandoids want to hear....



    I guess this is why apple never did anything to get speedstep working on their chips (atleast production operatingsystems). So no speedstep even when idleing....

    I suggest that you put anybody who dares quote me on the block list too.

    I believe that the A5 and A6 have on-demand cores - which means that they only need to run one core if the workload demands it. That achieves much of the same thing without requiring a separate chip. Time will tell which approach is better.







    Quad core Tegra plus one companion (low speed) chip.







    Yes, but history suggests that being skeptical is appropriate. The made all sorts of performance claims in the past that weren't true, so it makes sense to take their current claims with a grain of salt.







    But IF Nvidia were able to offer a clear performance advantage, there would be nothing stopping Apple from switching.



    Nvidia is not king in the embedded space next to ImgTec. They don't stack up.

    Yes, the offer stands. Find any manufacturer willing to risk an afternoon meeting, and we'll see what we can do.





    It's heartwarming that you're defending the companies you normally vilify, and I guess I should be grateful that you're merely calling names here rather than threatening physical violence as you've been known to do, so kindly allow me to return the favor:



    Could you please explain how a MacBook Air isn't possible without a CPU other than the one it uses?



    Hint: the MBA already exists, and it pretty much rocks, stock CPU and all.



    I never said that a new CPU was needed. I simply pointed out that your assertion that you know more than the rest of the computer industry is absurd.



    And I would appreciate it if you would stop spreading blatant lies about me. I never threatened physical violence to anyone. Here or anywhere else.

    No, the A5 is a soc and the GPU is part of it.

    But is it faster for games than the A5. So how many polygons per second?



    J.



    Looked it up myself. It seems that the Tegra 3 is about 2.5 times as slow in MFLOPS.

    I suspect this is the same for polygons per second.

    You can continue arguing about that if you like, and no doubt you will, but it won't make any more sense no matter how much you type.



    If you had said simply that it didn't require a new CPU, you would have been correct and no one would have disagreed with you. But you said you could do a better job than Dell, HP, Acer, Asus, Intel, Lenovo, and everyone else. That is, obviously, BS.

    But your willingness to retract your previous attraction to violence is heartwarming. Apology accepted.



    Are you that stupid in real life? Or are you simply so uneducated that you've never heard the expression 'slapping around' to apply to defeating someone's arguments?

    I'm with mdriftmeyer here.



    Nvidia's only chance here is in the GPU portion (their own creation) is demonstrably better than the competition. Considering that Imagination is mopping the competition at the embedded level with PowerVR I kind of doubt Nvidia can really make a beach head here.



    Nvidia is simply using a MP A9 core. EVERYONE is going to have product with this same core and larger volume customers with in-house design teams like Apple will be able to tweak the cores to good effect.



    As for the ARM 7 chip on the side. Bah. ARM has already announced their A15 will run in a big.LITTLE configuration with a A7 processor mated to a A15. Vendors won't even have to alter their software significantly.



    I can't get all excited about knowing a quad core A9 is coming when the A15 is so much better being an deeper pipelined OoO SoC.



    I think the A6 = MP A9. A7 = A15/A7 combo with Rogue graphics.

    Please stop making yourself look foolish. It really bugs me when the idiot trolls think that their ability to type a sentence on a forum like this instantly makes them an expert.

    As a current owner of the Asus Transformer the Prime is high on my tech shopping list. I really enjoy using it, not sure why all the bad comments about Android, might not be as well polished as IOS but I've started using it a lot more then my iPad. No need for iTunes to install a program, Codec support is awesome, Flash, better multitasking and all the those cool custom roms make my Transformer a pretty neat little multimedia machine. Course the iPad 3 will also be high on my shopping list, gosh I love tablets.

    If you mean iTunes desktop. I rarely use it to install programs I'm downloading everything over the air.



    Codec support - I use Azul and it plays everything I need it to



    Flash - Dead



    Multitasking - does what I need it to do.



    I'm actually thankful for Android because it's delivering to all of us better and more competitive products regardless of platform.



    I think the next battle is ecosystem. Google's web centrism versus Apple's iCloud vs Amazon's online store and Datacenter.

    From the demo (i know i know, nVidia demos need to be taken with a hefty helping of salt), it seems pretty seamless:

    I think Kal-El has this as well, unless I'm reading the anandtech article on it wrong:

    Quote:

    The A9s in Tegra 3 can run at a higher max frequency than those in Tegra 2. With 1 core active, the max clock is 1.4GHz (up from 1.0GHz in the original Tegra 2 SoC). With more than one core active however the max clock is 1.3GHz. Each core can be power gated in Tegra 3, which wasn't the case in Tegra 2. This should allow for lightly threaded workloads to execute on Tegra 3 in the same power envelope as Tegra 2. It's only in those applications that fully utilize more than two cores that you'll see Tegra 3 drawing more power than its predecessor.

    nVidia has a reputation for over-promising and under-delivering, so skepticism and salt are warranted

    Get out from the 1990's.



    This is 2011



    It's not about "megahertz" war, but rather "number of cores".

    Oh, by the way, this is an nVidia PATENT PENDING technology.



    That little bit of information seems relevant in this day and age. :P
