Tegra 3 GPU: Making Honeycomb Buttery Smooth

The bigger impact on the overall experience is the Tegra 3's GPU. If you remember back to our initial analysis of Tegra 3 you'll know that the GPU is not only clocked higher but it also has more execution resources at its disposal. To further improve performance, per "core" efficiency is up thanks to some larger internal data structures and tweaks. The end result is much better gaming performance as well as a much smoother UI.

Tasks like bringing up the apps launcher or even swiping between home screens are finally far above 30 fps. While Tegra 2 didn't have the fill rate to deal with some of the more complex overlays in Honeycomb, Tegra 3 does. The move to Tegra 3 makes the Honeycomb experience so much better. This is what it should've been like from the start.

Gaming performance is also significantly better as you can see from our standard collection of Android GPU benchmarks:

GLBenchmark 2.1 - Egypt - Offscreen 720p

GLBenchmark 2.1 - Pro - Offscreen 720p

BaseMark ES2.0 - Hover (1024 x 768)

BaseMark ES2.0 - Taiji (1024 x 768)

Performance is still not quite up to par with the iPad 2, but if we look at GLBenchmark's Egypt test Tegra 3 doesn't do too bad. The gap grows in more texture bound tests but in a heavier shader environment Tegra 3 isn't too shabby. While it's clear that Tegra 2 wasn't enough to deal with the 1280 x 752 resolution of Honeycomb tablets, Tegra 3 seems well matched.

Note that the BaseMark ES2.0 tests run at FP16 on Tegra 2 and 3 vs. FP24 on the PowerVR SGX 543MP2.

    But what reason can you give for not getting an ipad? Too much software selection? Too great of an ecosystem? Too much wireless video streaming to your TV? Too high of resale value? Too easy to use?

    Curious minds want to know!

    How about bad value for money? For the price of a 32GB Prime you get a 16GB iPad 2. It has roughly half the specs of the Prime: only 0.5GB memory, dual core processor v.s. quad core, lower resolution and screen size (which is REALLY annoying for watching 16:9 ratio videos, which is to say more than 1/2 shows/movies you can buy/download) and lack of expansion slots.
    In terms of software, iPad is smoother than android but at the same time you get a very limited browsing experience with iOS. I know HTML5 is the "future" but at the present is still dominant and will be for a while.
    As for apps, whilst there are less app choice, It has a good range - you may have less choice in each department than iOS but you will always find apps suitable for your needs.
    Build quality, at least for the prime, is also a lot better than the iPad's. Whilst both use aluminum instead of cheap plastic, the prime uses Gorilla glass rather than normal glass.
    For $500, the transformer prime gives you a much, much better product. Apple products are very good and generally blows away low-mid range non apple products but when you compare apple's products to similarly priced alternatives, they just don't deliver acceptable quality for your money.
    For example, a current generation MacBook pro 15" costs £1.6K. A HP 15" with virtually identical specs costs £800. The inclusion iOS does not justify a 100% markup on a windows PC. FOr £1.6k you can buy a laptop much, much more powerful than the £2k MacBook pro. The iOS may be better but is not worth £800. Furthermore to get full functionality out of a Mac you have to buy windows for bootcamp, which is another £120. By choosing a similarly priced alternative to apple products you "miss out" on an apple OS but gain much better specd products. I don't mind paying more for a better product but I expect the quality of the product to match the price and you just don't get that with Apple.

    One criticism of the original Transformer was that the charging cable was too short. Have they addressed that issue with the Prime? If not - is a USB extension cable a reasonable solution to address a too short cable or is there an issue with the about of current being pushed down the cable to charge the tablet in a shorter time than the mini usb.

    That is a fantastic screen! I'm very surprised and impressed. Reply

    1) G3 USB stick test
    There were a lot of questions regarding the G3 version of the tablet.
    Is there a possibility to test any G3 USB stick on the Transformer Prime dock (example 50 USD/euro G3 usb stick from Archos G9)? It would answer all these questions.
    2) Skype video call test
    Skype is may be the most popular video app available for a lot of Android devices. Would it be possible to make a Skype video conference call test and confirm if the Skype app works with video on Transformer Prime?
    3) MX Video Player test
    I really like the MX Video Player which also has full support for multi-core processors, subtitles, mkv/m2ts/mp4/... file formats, etc. Is it possible to test MX Video player too?

    The possibility to play multi format video files is indeed excellent feature of the Transformer Prime.
    Since the video file are quite large in size playing them from a home DLNA server via WiFi is important too (example Vuse torrent client DLNA server and playing by any third party DLNA client app like Skifta, iMediaShare, Bubble UPnP). Is it possible to test the DLNA video streaming of 720p/1080p videos?

    for tablet/smartphone market, except Apple. Why? because it's so software/os dependent. With an open platform like Android/Window, it's very hard to harvest the extra resources.

    If you look at the PC market, the quad-core is for heavy gaming and server while the dual-core is the most generic CPU for every laptop/desktop out there. And that is with a matured market with matured OS and application.

    I would doubt that Apple would go quad-core, but they are the only one can do it because they control both software and hardware. The rest? stick with dual.

    Having a quadcore fast machine is good!
    However, there are not sufficient programs out there, really needing all that performance!
    Most programs are smaller apps you can run with a single core running half the CPU speed!
    And most games, 3D games run perfectly fine on a cortex A8 or A9 processor.

    A pitty that software for Android is lacking behind!

    That's the whole Asus Transformer Prime. It can use an integrated keyboard dock, to look much like a Zenbook. The hardware is similar. Reply

    "Scrolling is rarely as smooth as I'd like it to be via the dock's trackpad. Many times the gesture just won't register on the trackpad or the trackpad will detect my two fingers but it won't scroll."

    We have this problem with my wife's Eee PC netbook. It is very annoying. We are looking to replace her aging notebook and will not be buying one without scroll bars on the trackpad. The probably means no Asus. The trackpad is also hyper sensitive so it makes accidental touches while typing a nightmare. There seems to be no sweet spot when adjusting the sensitivity. This is in contrast to the trackpad on her first generation Eee PC which is excellent.
