CPU Performance

The Galaxy S 5 marks the second Snapdragon 801 based device we've reviewed at AnandTech, the first being HTC's M8. I've gone through the Snapdragon 801 in depth already, but we're basically dealing with a reasonable upgrade to Snapdragon 800 on an improved 28nm HPm process. The bulk of the improvements impact GPU and ISP performance, but the SoC is just better overall. GS5 owners are lucky as all versions of the device that use Qualcomm silicon feature the MSM8974AC v3 SKU, which includes four 2.5GHz Krait 400 cores and a 578MHz Adreno 330 GPU.

MSM8974AB v2 S800 2.3GHz 550MHz 320MHz 4.5 N 933MHz
MSM8974AA v3 S801 2.3GHz 450MHz 320MHz 5.0 Y 800MHz
MSM8974AB v3 S801 2.3GHz 578MHz 465MHz 5.0 Y 933MHz
MSM8974AC v3 S801 2.5GHz 578MHz 465MHz 5.0 Y 933MHz

Although Samsung was the first major OEM to be caught cheating in Android benchmarks, it appears to have completely abandoned the practice with the Galaxy S 5's shipping software. Not only was I unable to find any evidence of the old cheats, I couldn't find any evidence of HTC's new subtle cheating either. The Galaxy S 5 appears to be clean as far as I can tell. Kudos to Samsung on doing the right thing, and I hope all other OEMs take this as a sign to stop the silliness.

For our performance tests I turned to our usual suite of browser and native applications. If there's one obvious takeaway from our CPU tests it's that despite having faster silicon than HTC's M8, the GS5 isn't always faster. I believe this has more to do with thermals than anything else. HTC's metal chassis is able to do a better job of dissipating heat than the GS5's plastic chassis. I don't believe there's a substantial impact on user experience, but it's interesting to note how choice in materials can have a performance impact like this.

GPU Performance

GPU performance remains where we see the biggest benefit from Snapdragon 801 vs. 800, and since the GPU gains are almost entirely due to frequency scaling it's not too surprising that the M8 pulls ahead of the GS5 here in most cases.

There aren't any surprises here. The Adreno 330 in the Galaxy S 5 is more than capable of driving the device's 1080p display both in current and near term future 3D games.

NAND Performance

The GS5 ships with 16GB or 32GB of NAND internally on an integrated eMMC device. Expansion is supported through a microSD card slot behind the removable back cover. Although the Snapdragon 801 inside supports eMMC 5.0, that alone doesn't guarantee a substantial increase in NAND performance. Keep in mind that most OEMs find multiple sources for their internal eMMC/NAND solutions, so what I'm testing here may only be representative of a portion of all GS5 devices.

Samsung sampled a 16GB GS5 review device. I put it through our usual random/sequential IO tests on a 100MB span of LBAs.

Random read performance is disappointing, it falls behind all modern devices we've tested. Random write performance is middle-of-the-road at best. It's unclear to me if this is a cost optimization or a lack of concern for NAND performance, but either way I'd rather see these metrics improve rather than regress.

 

Internal NAND - Random Read

Internal NAND - Random Write

Sequential read/write performance both improve handsomely compared to the Galaxy S 4. I can see why Samsung would want to optimize for these two cases as they are quite common in regular usage, but random read/write performance can also significantly impact user experience.

    just remove the touchwiz UI!
    every single samsung device has lags because of it!
    after installing google edition\diffrent roms that not based on it, the lags dissappeard!
    the UI is their most weak point, no matter how fast the cpu\gpu or ram will be, the ui, after several software insallation will L-A-G. just go over youtube and see it for yourself! wether it is GALAXY note 1,2,3 or galaxy s 12345, or tabs. they are lagging! (except google edition)

    That is a deliberate feature put there so that you will upgrade to a "faster" phone. Reply

    The GS4 is the most stable phone of 2013. People who has actually held a phone know that people like you and xsoft7 are just trolling.

    Give it up. No one cares about your opinion.

    In my opinion Galaxy S5 does not reach up to the same level as the competition, even from other Samsung phones (see http://www.consumertop.com/best-phone-guide/ ). For example HTC One M8 and Motorola Moto G are fantastic. But we can agree on one thing – Galaxy S5 wipes iPhone off the table any time of the day. Reply

    I hate to break it to you, but how stable it is when using apps isn't exactly relevant when using touchwiz. On my friend's S4, there is noticeable slowing when doing motions in the basic UI, which is what we are talking about. Reply

    I hate to break it to you, every phone, no matter brand or OS can be slow if you install the wrong apps.

    Your "friends" phone is completely irrelevant to everybody who's actually used a GS4. Because we know you just full of it. How do I know I am more right than you? Because I know which Android phone is dominating sales. By a gigantic margin. If anything of what you're making up is true, Samsung wouldn't be as dominant, no matter how much money they would throw at their marketing department.

    Dominating sales has nothing to do with what you're describing. Have you tried the google play version of the galaxy s? The one that comes with stock android and doesn't feature the silly overlays? Yup, runs more stable than the "regular" galaxy s and actually gets updated in terms of software.

    The reason why manufacturers drop those skins is not so they "look different" only but because they can somehow rationalize not updating the software on the device later and force you into an upgraded device sooner.

    Anyone buying a non-nexus phone is in this boat unless they want to do some work on their own to keep the devices up to date and that doesn't always quite work out right in terms of stability.

    Even Nexus phones are not always updated immediately as we have seen in the last year. Reply
