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.

    do you have to post the review as soon as the NDA is lifted? If that is not the case, why not wait a few more days to share the final review? I enjoyed reading what is present right now but was just wondering. Also would you recommend waiting till Win8 tablets if I have no necessity for tablets this very moment?

    Sounds like you answered your own question.

    Yes, they have to post as soon as the NDA is lifted because first reviews = page hits.

    It's generally a good idea to have something up when the NDA lifts (plus, if you don't have something up when the NDA lifts manufacturers may think you don't need to be sampled alongside those who do post when the NDA lifts). In the PC space this is rarely an issue since we normally get 7 - 40 days with a product before the NDA lifts. In the mobile space it's a much bigger problem as many reviewers seem to be ok with a 2 - 24 hour testing period (+time for writing). As I mentioned in the article, I fully expect this to change over time (and I'm actively campaigning for it to change), it just doesn't help when ASUS contributes to the problem. To ASUS' credit however, I don't believe this was ultra intentional but it happened nonetheless.

    The tablet space is one area where you should wait if you can. The segment is evolving too quickly.

    Take care,

    You have to give them a pass though, clearly their #1 goal is getting it out to stores before Christmas and they had to compress their entire release schedule, not just the delay between shipping it to reviewers and lifting the NDA.

    Why not do a first impression and an in-depth review after a few days?
  • metafor - Thursday, December 1, 2011 - link

    That seems to be the better way of it. The problem with mobile launches is that they do occur very hot-off-the-press in terms of final software/hardware release. They occur so often every year and there's such a race to compete that even if you got a sample very early on, it likely would not have had nearly as complete a software stack.

    This was our first impression post :-P The replacement Prime arrived this morning and I've been working on it since it showed up :) Expect more in the coming days.

    Take care,

    Sadly, they do. The reason for this is to get the page views. Yes, a more thorough review would be great, and it'll come. For now though, they have to keep up with the competition of suffer the lost visits.

    I felt like I did as best as we could given the WiFi issues of the test sample, more is coming though...

    Take care,

    is it only me that hates that ugly black border around virtually every tablet since the iplod?

    I mean what wrong with having screen to the edge? Somewhere to put your fingers? pfft ill trade that space for working area and hold it at the edge, or if not make it smaller for my pocket
