AndroBench comparison - the Samsung Galaxy S6 & S6 Edge's memory speeds obliterate other flagships

AndroBench comparison - the Samsung Galaxy S6 & S6 Edge's memory speeds obliterate other flagships
For the Galaxy S6 and S6 edge, Samsung brought forth UFS 2.0. Think of UFS 2.0 as the next big thing for mobile devices after the ubiquitous eMMC standard found in all devices operating with NAND flash memory. UFS has up to four times faster data transfer speeds. For example, eMMC 5.1 - the standard's latest version - achieves transfer speeds of up to 250MB/s (read) and 125MB/s (write). The older eMMC 5.0 standard is no slouch either, and is found in most top-end handsets powered by Snapdragon 801 chipsets and above. That's impressive enough, but UFS 2.0 HS-G2 goes up to 725MB/s, and HS-G3 has a peak speed of 1.45GB/s. Woah!

Additionally, unlike eMMC, UFS allows for simultaneous read/write processes, and prioritizes incoming commands as to execute them as quickly as possible. Speed improvement aside, this gives it an additional edge over good old eMMC. And while UFS 2.0 is more energy-consuming compared to the frugal eMMC, it makes up for this by getting stuff done and going to sleep quicker! Outta boy.

The introduction of UFS 2.0 memory to Samsung's high-end mobile devices - at the time, we could only speculate it was the Galaxy S6 and Galaxy S6 edge - certainly piqued our interest. There was no way those speed improvements we spoke of above wouldn't impact their performance across all usage scenarios - especially when it comes down to app and file load times! Thankfully, at MWC 2015, we managed to put a pre-release Galaxy S6 edge unit through the AndroBench memory speed benchmark test to hunt down any measurable improvements. It's certainly the right tool for the job, seeing that it's able to measure random and sequential read and write memory access speeds. What does that stand for as a performance metric?

You've never seen anything like this in a smartphone!

Now, the truth is that when it comes to flash memory, the concept of random and sequential reads/writes doesn't really apply, because it comes from the world of hard disk drives. But just so you get the general gist of it - in random read and write operations, blocks of data aren't written in neat, organized clusters, but randomly spread all over the disk space. This is usually the case with most user applications, and in hard disk drives, it results in a reduced data throughput. That's because it involves lots of spinning of physical plates and a hard drive head rushing to get to the correct chunks of data in time, introducing latency - the original performance killer.

Sequential read and write speeds are important in regards to accessing and storing large files (such as high-resolution multimedia content). Single large files tend to be stored in uniform clusters of data on a singular region of disk space, in easy to follow sequences. Thus, even though flash memory doesn't really care how data is arranged, good sequential read and write speeds means nice performance in file operations. And with those hi-res video files and losless music taking up sizeable chunks of our mobile devices' disk space, it goes without saying that sequential read and write speeds matter.

With all that into account, let's see how Samsung's flagship smartphones compare with the best of last year's technology in terms of memory performance. Looking at the impressive results posted by the former, it seems Samsung wasn't joking at all when it rallied about the Galaxy S6 & S6 edge's memory speeds. You've never seen anything like this in a smartphone! Unfortunately, it will be a while before UFS 2.0 memory reaches to mid and low-end tier devices, because right now, it's rather expensive to produce and is, thus, going to be a feature of flagship products.

No one even in this article mentioned anything about the Galaxy S6 is the first phone to use DDR4 ram. The vast majority of smart phones currently on the market are using DDR2 with only a handful using DDR3.

S5 received Lollipop before the HTC M8 did, which was back in January. If you want to focus your hate to no updates, Sony has yet to release 5.0 to ANY of it's devices.

How dumb do you sound? You're bragging about a Nexus receiving the 5.0 update before a phone with a HEAVY customized UI? Lol stop while you're ahead.

And from the looks of it, S5 was the #1 selling Android phone every single quarter across the globe - more than the M8, G3, Z2/Z3, and Nexus 5 combined. I would be more than happy for you to prove me wrong. Take your time, I have all day.

You said they don't get updates, but YOU JUST SAID the S5 is getting updates now. So they do get updates (maybe a little late but that's not the same as never). And no, benchmarks are not pointless. If they were so pointless, because every company uses it as a quantitative measure of improving their products over time.

@Teenaxta Troll harder somewhere else

Samsung has a 12 month release cycle for flagship phones. The Note and Galaxy S series are on different release cycles about 6 months apart, but the Note series is a phablet, not a "phone" so they are both a flagship in their own category.

S6 will be a cracker phone. Has the best screen, the best memory, the best storage, and is as fast as fk.

That's a lie. I've had my Galaxy S4 for almost 2 years now and it works perfectly. I'm running Android 4.4.2 and will be getting Lollipop just as I buy my Galaxy S6. The battery life in GS4 is still good too. After an 10 hour day of programming I come home and my phone still has 50-60% of it's battery.

It doesn't lag, you are just a moron who doesn't know whot to setup your phone correctly.

85. Scott93274 (Posts: 4109; Member since: 06 Aug 2013)


Every phone from every company get's replaced every year. Many companies have multiple flagship devices. So your reason for singling out and hating on Samsung is a bit idiotic. Also, point out three times when there was an advancement in performance over a previous model phone for any company? The only one that I can think of that comes anywhere close is maybe the iPhone when it went 64 bit.

So I have to ask, why spend your money on anything when you know full well that the next year will see a better model? Why buy a car? Why buy a computer? Why buy a phone? Why buy a camera? Why leave your cave when the world is always constantly changing. It's a big and scary world full of phones that will one day be obsolete.

Can anyone with technical background clarify that if Samsung had indeed put a MicroSD slot in GS6 would that've crippled the memory speed of the inbuilt storage as well ?

Thanks.

15. djorn2k (Posts: 10; Member since: 03 Sep 2014)


The main reason for not including MicroSD in the GS6 is due to Android OS limitation on the slot. The second reason the transfer rate will be greater internal as oppose to the SD card. I think those are the two valid reason. The SD slot is mainly use to stored pictures and music. In general our society when it comes to data storage we are turn in to hoarder. The more we want that more we store garbage.

72. cheetah2k (Posts: 1507; Member since: 16 Jan 2011)


Yes it does, because Android uses all its onboard media for caching, as well as some applications get automatically swapped to external SD on installation.

It makes perfect sense. Get rid of all the bottlenecks to make a truly fluid phone. I get it Samsung, I really do.

Cant wait till April 10 :)

Exactly, a system is only as fast as its slowest part. Eliminating SD cards removes a major bottleneck and will keep performance consistent. Even the fastest SD cards can't break 100 MB/s in sequential read/write tests.

I don't know how much but it does a little.

There is a system wide I/O bus. It's the maximum speed data rate that can transfer between CPU, RAM, storage and SD card. For the Galaxy S6, it's a dual channel 64-bit one leading to max. speeds of 25.6 GB/s. Now if you were to not use a microSD card, all the pins that were going to microSD can be added to the internal storage making greater bandwidth available to internal storage.

The UFS storage requires a full duplex link. So yes, it requires more pins.

TL; DR: Yes, it would have affected internal storage speeds. But I can't say how much.

Although it wasn't me who asked that question, thanks for clarification. Also, do you know anything about supposed flawed support for RAID1 on Android. I've read on the internet that Korean LG G2 (F320L) with SD-card slot is performing slower then international unit (D802) with internal memory only and all other hardware is the same. I don't know of any other phone that has both SD and non-SD variant so G2 came to mind.

I already own D802 International unit. I was just curious if their is any truth in claims that Android doesn't handle RAID1 configuration properly. And 13,33% smaller battery isn't really a deal breaker since 3000mAh battery in G2 performs like a champ.

No the G flex 2 won't because it nerfed the performance to avoid overheating SD810, so their benchmark scores were low.

The Flex 2 and M9 also use eMMC 5.0 storage as do the Note 4 or Nexus 6. They would have suffered the same fate.

LPDDR4 doesn't help much here. It affects the I/O bus but the eMMC is so slow that the effect would be negligible.

You can't run androbench on a G Flex 2 as the SD810 overheats and throttles in the first run.
