iPhone 6s Sets Mobile Records in Early AnandTech Benchmarks

After spending some days in the company of the latest iPhone models, Anandtech summarized today what it has experienced and measured so far. Besides A9 SoC benchmarks, Anandtech points to a special yet undiscussed feature of the iPhone 6s: storage. It’s not the 16 GB storage option but the solution Apple has used: it has integrated a unique storage solution yet unseen in any mobile device, which propels the devices ahead of every OEM in the industry, Joshua Ho notes in his blog entry. Let’s see what Apple did.

Apple uses custom NAND controllers for storage in the iPhone. In the case of the iPhone 6s, it has taken the MacBook SSD controller and adapted it for use in the smartphone. The main difference between the two is that the iPhone’s NAND controller uses both PCI-E and NVMe, making it the first mobile solution to use both.

Here’s Ho’s technical explanation:

The controller is a critical part of any storage component, but without any NAND to control it’s a bit pointless. Fortunately, the NAND used appears to be exposed in the OS as it’s referred to as 1Y128G-TLC-2P. Breaking this down, the 1Y means that we’re looking at 1Ynm NAND process with TLC. The TLC portion might concern some, but as we’ll soon see it turns out that we’re looking at a hybrid SLC/TLC NAND solution similar to SanDisk’s iNAND 7232 eMMC and desktop SSDs like Samsung’s 850 EVO which is better suited to the bursty workloads seen in mobile and PC segments.

The best thing about such hybrid SLC/TLC NAND solutions is (in essence) that the SLC cache is large enough to “avoid showing the reduced performance of TLC NAND,” Ho explains. But you only have to take a look at the charts inserted below, and the numbers will convince you about the iPhone 6s’ impressive performance.

    Help. My new iPhone 6s Plus on fido only gets 3 bars and LTE speed is horrible. My 6 plus will always hit around 40mbps on LTE but the new phone is not going above 20. Anyone else having similar issues ? Please let me know

  • xxxJDxxx

    Hmmm. Just ran a speed test on my 6s. Around 21/8 mbps…

  • Kamal

    Phone shows it used 342mb of speed test app. I used it 3 times today. Looks like something is out of a whack either with the app or software

  • what were your average download speeds? 100Mbps?

  • Kamal

    Gary on the new iPhone 6s Plus am getting under 15. Last week i used to get above 50mbps on LTE fido on my 6 plus for months . Even the bars show 2 something is either wrong with my phone or fido or the software I think

  • poopchute

    I’m getting between 75mbps and 95mbps down, and about 25mbps up on my 6s with Rogers in Burlington. I was pleasantly surprised with my first speed test.

    While i’m not sure if this has to do with your slow speed but the 6S now has band 12 capability.
    You should probably check to see which band you are connected to by dialing *3001#12345#* then click on “Serving Cell Info”
    Also, to get the true signal strength, hold down the lock button till the slider appears then hold the home button. if that worked, your bars turn into the actual signal strength in -db

    If you have the more up to date Ookla speed test app, it should show how much data each takes used. Go to the results page then click on a test. It should have how much data was used for your download and upload.

  • Kamal

    Thanks I tried it and it says Freq Band Indicator is 4. This is
    what I see when I dialed that number. is this what you guys see?

  • Kamal

    Thats exactly what am saying on LTE usually in Toronto it clocks over 40-60.

  • Chris

    While i’m not with Rogers/Fido, band 4 AWS-1 (1700/2100Mhz) was the first band used for LTE in Canada. Depending where you live and who you are with, other bands may be available in your area. Some (like band 12/17 700Mhz) have very good distance but the channel isn’t wide enough for fast speeds.

    I’m with Telus and live on the east coast. My iPhone likes to sit on band 2 (PCS 1900Mhz)
