GFXBench 3.0: Manhattan And T-Rex

Qualcomm Snapdragon 801: Performance Previewed
By , with contributions by Alex Davies

We reviewed Kishonti’s GFXBench 3.0 a few weeks ago, and we think it’s a good addition to our benchmark arsenal. We appreciate both the variety and detail of its individual tests, especially the fact that they’re broken up into high- and low-level groups. High-level tests simulate the nature of 3D applications, in particular, games. They do so by rendering scenes with an incredible amount of detail, utilizing the kind of GPU-stressing effects that a high-end game might put into effect.

The high-level tests include both an OpenGL ES 3.0-level test (Manhattan) and an OpenGL ES 2.0-level test (T-Rex). Manhattan renders a nighttime city scene where a giant robot takes on armored tanks, all while colored spot lights move about the scene. It uses a combination of forward and deferred rendering, and a whole lot of real-time lighting, making Manhattan the most modern and demanding GPU test in our suite. T-Rex simulates an action sequence where a motocross biker is chased through the jungle by a lumbering Tyrannosaurus. While not quite as a modern as Manhattan, T-Rex still strains the GPU by using several demanding effects simultaneously.

Manhattan 1080p Off-Screen

Normally, we’d run both the native resolution and off-screen tests in a product review, but today we’re more interested in comparing SoCs rather than devices, so native resolution isn’t relevant.

The iPhone 5s and Samsung Tab Pro 8.4 take first and second place with extremely close scores. The Xperia Z2 places third. Technically, it should be ahead, or at least equal to the Samsung Tab Pro 8.4, since it sports a faster GPU core.

Samsung’s Galaxy Note 3 slips into fourth place, which is also strange, since the Note 3 features the same 550 MHz Adreno 330 GPU and TouchWiz software overlay as the Tab Pro 8.4; it should at least be on par. Our guess would be that the smaller device is throttling due to heat. After all, Manhattan is an aggressive benchmark, and the Note 3 is in a more compact form factor.

T-Rex 1080p Off-Screen

T-Rex is a demanding OpenGL ES 2.0-based test that utilizes many modern effects, including materials, high-res textures, motion blur, parallax mapping, and complex particle systems. It also uses complex geometry, planar reflections, specular highlights, and soft shadows as part of the render pipeline.

Here more than in Manhattan, the Snapdragon 801’s speed-boosted Adreno 330 really begin to show its worth, the Xperia Z2 takes first place with a five-percent lead over the iPhone 5s, and of course, that lead could increase with access to the SoC's peak memory bandwidth. Handicapped subsystem aside, this is the first time that a Snapdragon processor has beaten Apple's A7 in this test. Both of the Snapdragon 800 -AB devices fall behind the A7-equipped iPhone 5s.

Alright, so we’ve established that the Xperia Z2 tablet’s Snapdragon 801 is performing better than Snapdragon 800-based devices in GPU tests (despite pre-production idiosyncrasies). Now let’s see why.

    Will this chip go into the next Google Nexus device?

    hope not, it looks just slightly better than the previous snapdragon 800

    A Temash APU and Atom SoCs would make a great cross-platform comparison, here.

    The 'Droid Heads would love to see some Tegra 3/4 action, too.

    I really am looking forward to the showdown between the A7/A8, Tegra4/K1. and Intel "what is the name of the chip in the nexus 8?". I hoping to see a worthy $500 upgrade.

    Great article - very informative. Sorry if it's off-topic, but the HTC One (M7 2013) uses an APQ8064T. Did Qualcomm change the meaning of the second numeral from Snapdragon 600 to 80x? The HTC One M7 employs a modem yet now the second numeral being 0 indicates no modem. Or does the device substitute another modem off the SoC? Also what does the "T" suffix mean? :) 

    EDIT: I realized APQ also indicates no modem so I'll just assume that they supplied an off-SoC modem for the device. Still would like to know what "T"stands for.

    Isn't Tegra K1 (aka Logan) having something else? Project Denver CPU was supposed to be part of Parker SoC as per nVidia's 2013 Tegra roadmap, unless I am missing something.

    So if you already have a device with a snapdragon 800 you should hold off for a real improvement, like snapdragon 1000 or 1k or whatever marketing jibberish they want to name it.

    From Wikipedia :"SKU refers to a stock-keeping unit, a unique identifier for each distinct product and service that can be purchased in business."

    They compared two different manufacturers devices from two generations in order to extrapolate something about the chip? Huh? What about differences in hardware implementation, software, memory, and all the other things that can independently effect performance? Would have been much better to wait and have more comparable devices to test.

    This is one of the best Processor in Mobile technology , I love this processor lucky to that i bought sony experia m with this processor . Soon I will write review on my following blogs <a href="//www.GeekWeeks.com/">Geekweeks</a> <a href="//www.hditweb.com/">HDITWEB</a> <a href="//www.newsisoft.com/">newsisoft</a>

    My tegra 4 keeps up quite nicely.

    Why are they still releasing 32-bit chips when Apple already had a 64-bit chip?

    There is obviously something wrong with the memory subsystem (at least) on that Xperia platform you're using. In no way should the 801 have any regression compared to the 800. Did you contact Sony and ask if there's any known issues that would explain the results you're getting or just WTF is going on in general? As a result of the issue this article's headline should be "Sony's preproduction Xperia platform has issues" or somesuch. As it is, this isn't a real review of the 801.Also, I'm going to harp on this every time I make a comment on this website from now on: this comment system sucks. Badly. You need to find a new solution. Even the previous comment system was miles better.

    Indeed, and it's something we noted right from the first benchmarks we ran. It's even noted in the article - you can see it covered in the AnTuTu and Geekbench sections, specifically and throughout the other benchmarks we ran and analysed. It's clear that tablet had some definite issues with it's memory and I/O subsystems. I think it would've fared substantially better had they been resolved.

    Yes, I know it was referenced in the article. My point was that the issue which is clearly with the device is substantially affecting the results, and therefore this article doesn't really live up to being a preview of the Snapdragon 801's performance.I recognize that it's not your (the author's) fault, but still. Also, my question still stands: did you guys attempt to get any feedback from Sony about the issue? The possibility of getting a sample that works properly?

    I'm not sure that's entirely fair - we did prove that the MHz boosted Adreno 330 of 801 is substantially faster in tests where MHz matters - fillrate, for example. In that test it does beat an 800 AB (Galaxy Tab Pro 8.4) device quite soundly. At the time the results were recorded there were no other Snapdragon 801 devices in operation - in fact, the results were take from a Sony Xperia Z2 Tab at a press junket, which explains why it's not a final device. Sometimes we have to take what we can get. Of course, we will be following up on a more detailed review of a final device as soon as we can. Also, we'll be reviewing another Snapdragon 801 device very soon. Can't say much more. :)

    LG G3 will be Snapdragon 805, so if this is the phone the new nexus is taken from then.. It looks like Lg might get a third go at Nexus.

    There's a typo at the end of the second to last paragraph on the second article page. You wrote "801 9874AC" when I think you meant "801 8974AC".

    Note 3 does not have a 8974AB right?im sure the Note 3 uses a 8974AA as the GPU clock in definately 450mhz
