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.

    It's a shame that Nokia picture samples aren't included in comparison. Either Lumia 1020, 1520, or Icon (930). Heck, even an older 920/925 would be adequate. Reply

    Yeah I wouldn't mind a Lumia being included in the comparisons, then we can see how every platform stacks up in these reviews. Reply

    On top of that it would be nice to see the results of at least some windows phones on the graphs. I can understand that a lot of windows phones have lower end hardware because they aren't very resource intensive, and thus probably don't always top the benchmarks, but it would be nice to know how they compare. Even if it's just a single entry at the bottom as an "FYI" Reply

    I believe the review lacks the comparison with Windows 8 phones, because this site has no reviews with ANY Windows 8 phone. It just avoids them. At least Brian Klug did that. So, if he's not around, the better the things will be. Let's see if anything changes here. In the mean time, as far as smarthpones goes, I read mainly other sites. Reply

    Doesn't the Sony use the same camera hardware? Reply
  • melgross - Tuesday, April 8, 2014 - link

    Did you read the whole review? If you did, you would have read that this is Samsung's own sensor this year. Reply

    Yeah, I'm curious if Anandtech is still going to ignore Windows Phone entirely (as far as full-length reviews go) as it has since the WP8 was initially released. I guess time will tell. Reply
  • wrkingclass_hero - Tuesday, April 8, 2014 - link

    Did Brian Klug leave? I haven't seen anything written by him in a while, and his twitter hasn't been updated. Reply
  • BMNify - Tuesday, April 8, 2014 - link

    yeah, good to see that Brian Klug is no longer writing for Anandtech, he personally hated Windows phones and used to mock them publically. Also, there was no review for Nokia phones eventhough Nokia sent all the flagship models last year like 920,925, 1020 to Brian Klug.

    And from what i can make out this fiasco has led to Nokia no longer inviting Anandtech to their events and no samples too, hopefully Anand or the new writers can restore the relationship.

    Yea I agree they seem to ignore that platform completely. They reviewed the HTC 8X but that is the last I saw out of AT here. Reply
