    I meant performance potential in the hardware, of course. That doesn't include possible low-level optimisations. And as far as we know, that "+" could mean something negligible.

    But let's not forget that iOS can actually be considered a closed environment on its own. It's not like they'll have to develop drivers for a multitude of hardware combinations like Android (and WP7 in the mid-term future?).


    That said, I doubt any developer will spend big loads of cash to develop AAA titles for the iPad2 anytime soon, like they will for the NGP, and that's where the low-level optimizations are made.

    Depends on the perspective really, how "negligible" it actually is. Just for the record you can have all the hw potential in the world and the result could be underwhelming due to inferior sw/drivers.

    That shouldn't mean that Apple's sw platform is inferior or any of the sorts but there are still quite a few differences between a hand-held console and a tablet or smart-phone.

    No it isn't compared in the sense it is on any (hand-held) console.

    An ISV could even develop an el-cheapo 5 bucks short title for the NGP and still have the low level API advantages. Oversimplified you are able to address the underlying hw more directly and I doubt Carmack is wrong when he claimed that it'll give NGP an advantage over an additional hw generation from the smart-phone realm.

    Remember it will be out next week, while NGP won't be out for almost another year?

    Shortly after the NGP releases, we could have SOCs which approach the NGP's profile.

    I think NGP is supposed to be OCT (7 months) ?

    Sometime in Q4, but AFAIK it's not clear yet if it's just gonna be Japan, US or worldwide.

    Though iOS standards are not as open as a PC's, they're still abstracted enough to allow direct and easy compatibility across multiple generations in contrast to dedicated platforms for dedicated consoles.

    It's being reported now that Apple is going to move SoC production to TSMC including the A5 for the iPad 2. This is strange after the report that Apple quadrupled wafer allocation at Samsung. It'd make sense to do the next A6 on 28nm, but does Apple really need more A5 then the increased production at Samsung would provide? Moving the A5 to TSMC would no doubt require re-laying out the chip. Is a few nm or other differences in TSMC's 40nm process really that much of an improvement over Samsung's 45nm process? Unless one of these reports is wrong.

    Although it could make sense that Apple produces the A5 for the iPad 2 and iPhone 5 at Samsung, along with the A4 for the iPhone 4 which looks to see continued strong demand with reports that the CDMA iPhone 4 is looking to launch in Asian countries later this year even after the iPhone 5 is released. The 5G iPod Touch, being the usual process guinea pig, could get the TSMC A5 along with a possible fall iPad 2.5 or iPad 3.

    Gruber has some interesting testing on the relative graphics capabilities of the iPad and iPad 2. Looks like Apple's 9x raw graphics improvement gains are reasonable and the weak fill-rate issue has been resolved.

    (Hopefully the long quote doesn't infringe on any copyrights.)

    Can't wait to see games that pushes the iPad 2.

    It seems more and more like a powerhouse, especially when compared to other tablets.

    So, 512 MB confirmed then. Disappointing but still an impressive product overall.

    Pixel warm up test is notably near the 250 MHz x 4 TMU theoretical. Like the Kyro benchmark days.

    Nice to see it stretch its legs a little more in some of those tests.

    What's a pixel warm up test anyway? (honest question)

    Sounds like it might be a little more synthetic than the other pixel and triangle fill rate tests it replaced in the other versions of GLBenchmark, or maybe just a name change. Not really sure how the test runs...

    Maybe Laszlo will stop by.

    The offscreen Egypt result for Exynos is quite low compared to the standard one and it's a phenomenon that appears on various so far tested platforms (like iPad1 and others). It's too early for comparisons IMO; I'm sure most if not all of them will be chasing after performance improvements for 2.1.

    ***edit: self correction: Kishonti just added a "720p" next to the offscreen in their results. Else its running when in off screen at 1280*720? Well that explains a lot then. Else for the moment irrelevant wether Hardkernel Odroid A or Galaxy S2 at offscreen 720p the iPad2 is a tad more than 2x times faster in Egypt or PRO.

    Finally, the offscreen tests should now allow some level of direct comparison between devices with different display resolutions and where vsync limits are kicking in....
