Graphics Performance: Adreno 320 Under GLBenchmark 2.1 And 2.5

Snapdragon S4 Pro: Krait And Adreno 320, Benchmarked
By

Fortunately, it's easier for us to evaluate graphics performance. Let's start by running off-screen tests using GLBenchmark 2.1.

GLBenchmark 2.1

Our benchmark results tell it all. The SGX543MP4 in Apple's iPad 3 is the performance king at 1280x720. Qualcomm's Adreno 320 nearly matches Imagination Technologies' work in the Egypt test, but falls short by roughly 30% in the Pro benchmark.

The effective fill rate of the PowerVR GPUs is good, and that's a big advantage for Imagination Technologies, since mobile game developers tell us that fill rate is a primary bottleneck in their work. 

Although Adreno 320 is routed by the SGX543MP, Qualcomm still deserves recognition for improving its graphics architecture. The Adreno 320 serves up three to four times as many frames per second as Adreno 220, and its fill rate is more than six times higher. 

GLBenchmark 2.5, OpenGL ES 2.0 benchmark for 1080p

Over time, today's most prolific resolutions will evolve into higher-def screens. We've already seen Apple's third-gen iPad 3 enable 2048x1536, necessitating more powerful graphics hardware in the process. Clearly, it'll become increasingly important to benchmark mobile graphics architectures under more demanding circumstances. Today, the best we can do is Kishonti's latest GLBenchmark 2.5, which continues to primarily test OpenGL ES 2.0 features, but now specifically targets 1920x1080 and higher-quality textures.

Under the duress of what GLBenchmark 2.5 applies to each graphics subsystem, the results change. Qualcomm's Adreno 320 emerges victorious over Imagination's SGX543MP4. The margin is really pretty small, and the Pro test that favored PowerVR graphics previously is no longer part of the benchmark. So, the swap isn't quite decisive. But it's at least interesting to see Adreno maintain more of its frame rate in this more taxing workload.

Unfortunately, Qualcomm can't achieve the fill rate of Imagination's tile-based deferred renderer. The Adreno 320 does, however, improve greatly on last-generation's Adreno 220 implementation.

    Naw, more like give foxconn workers better salary, do something good with mountain of money they have, stop patent trolling, stop silly war with google/samsung and stop lieing. Then maybe Apple will be forgiven.

    No comparison with Samsung exynos4 ?

    Tegra 3 is complete overhyped trash. abysmal memory bandwidth and weak GPU performance with useless extra cores.
    Why isn't the exynos quad in the comparison?

    Well, it'd be a start. I wouldn't go nearly as far as all is forgiven.

    AFAIUI, the PowerVR GPU in ipad3 is more of a brute force architecture. "Just throw more transistors" is its mantra. So its good in current workloads.
    The Adreno320 is more refined and optimised arch. Trying to get the most performance from least silicon area. It is still being refined. Hence, it will do well in future applications.

    This just makes the tegra 3 look bad.

    Why the ST-ericsson 8500 isn't in this list either? too few phone out? Xperia S/P... looks it would rock some of concurrents.. omap..S3...
    Please be as exaustive as possible ;)

    Error in the chart on second page.
    The cortex A15 DMIPS/MHz should read above the A9. Around 3.5 DMIPS/MHz from the rumblings.

    These krait numbers aren't very impressive if you normalize for clockspeeds.
    In fact, they seem to suggest only a very small improvement over A9, if any at all.

    Why placing only the weakest version of Tegra 3 and not Tegra 3 T33 (ASUS Transformer Pad Infinity 700)??? Or both of them.

    This is a pretty good article, but I have one problem with it: the Tegra 3 is probably not the best example for the Cortex-A9. It's hobbled with very low memory bandwidth. It could probably perform better (including the GPU) with a better memory interface. Nvidia made a major design mistake with that.

    Nice article.

    You might want to fix (bold) the 'Aggregate Performance Per Core' chart; note the Plus & Pro numbers.

    No. PowerVR holds some very specific advantages over there competition... Such as shader-driven tile-based deferred rendering (TBDR) architecture.... and their GPUs are actually MORE efficient than their competition. Not less.

    It's still very impressive what Qualcomm's done... I'm just not thinking they'll dethrone PowerVR anytime soon as the mobile graphics performance leader.

    It's interesting that the S4 needs 1.5 Ghz to beat the Tegra. And that's a high end Snapdragon vs bottom of the line Tegra. I'd bet that at the same clock rate with a level playing field these two would trade blows. This tells me that the Snapdragon is still way behind Tegra. S4 isn't in any production hardware and Nvidia is going to release the next Tegra chips in a few months.

    When Tegra and Snapdragon devices are available at the same time I'd bet that Tegra will handily beat Snapdragon. I wouldn't say Qualcomm is back in the fight, I would say this is Qualcomm's last desperate attempt to stay relevent

    Good Review. I'm curious as to how accurate your "aggregate" single core performance numbers are to a real single threaded benchmark. I'm not an expert, but I thought the memory controller and GPU were separate from the CPU Cores. Can you simply divide those benchmark numbers by 4 to get single core memory and multimedia performance?

    this soc shall be at the heart of my next phone.

    Google, please allow the next nexus to be powerful, and have expandable memory.

    Enough imitating apples cloud dreams, we want local storage!!!!
    64GB microsd card is $48 on pace to be $36 by next year.

    Now , let's wait and see until some phones/tablets come on the market with the S4Pro .
    BTW , why are the Exynos4 and the A6 missing from the review ? I think they are the most relevant competition to the S4 .
