Intel 750 Series 1.2TB NVMe PCIe SSD Review

PCMark 8 Real-World And Advanced Software Performance

PCMark 8 Real-World Software Performance

Service Times

I often read user comments about flat performance across different products. Of course, SATA limits throughput to 6Gb/s. Even without that ceiling, though, information can only move as fast as the workload allows. NVMe lifts some of the technical restrictions, but we still need workloads about to utilize the performance available. 

Only one test on the daily use software performance charts shows a large differentiation between products on the chart: Photoshop Heavy. That test demonstrates a 13.5-second difference between the slowest model and Intel's 750 Series 1.2TB up top.

Throughput - All Tests

The throughput performance measurement accounts for all workload tests from the daily use software list. The 750 Series is excellent in this suite, though not even the benefits of NVMe can unseat Samsung's SM951...at least not without the heavy conditioning you're about to see.

PCMark 8 Advanced Software Performance

Throughput Tests

Heavy preconditioning changes the landscape entirely. Previously, we saw the SM951 ahead of Intel's 750 Series in several tests. The Samsung SM951 rocks under client workloads, while the 750 Series is faster under heavy use. Professional users running demanding workloads take note; Intel's 750 Series is the superior product if you can use it effectively.

Service Times

NVMe reduces latency across the board under heavy loads. This is one of the most significant tests in our review, since it's indicative of a better user experience. The Intel 750 Series 1.2TB delivers performance at nearly half of the latency we measured on Samsung's SP941 512GB.

    Typo on the 1st page, it states, "Up To 22400 MB/s" for sequential read.
    Presumably that's supposed to be 2400. ;)

    Ian.

    PS. Would be handy to include just one good normal SATA SSD as
    a comparison reference, eg. 850 Pro 512GB.
  • CRamseyer
    Thanks Ian, we'll get the typo fixed ASAP.

    Let me see what I can do about putting a 2.5" performance drive in the charts. I'm building new charts now for PCIe-based devices.

    Looks for the other SM951 capacity sizes and Predator soon.

    For those of us that don't have these number in our heads, I get no real sense of how fast this really is compared to my ssd.
  • unityole
    from what I see, intel with lower performance number is likely due to lower performance controller or flash or firmware, whichever it maybe we all know samsung like to clock controller/flash higher for better looking performance. reason that random write at QD1 is so fast probably because of NVMe. can't wait to see this go up against SM951 NVMe.

    from HDD to SSD you see the huge latency drop by about 50x, where as fastest SSD compare to ram is maybe 30-50x dependent on ram/ssd. with NVMe can look forward to at least another 3x loss in latency.

    basically it'll be so much more snappier than your ssd for sure.

    Does this quote from page 5 apply to this card: "In time, we hope to see a RAID 0 NVMe boot environment that would give this test a little more meaning."

    Is this card bootable in Windows 10 or not?
  • CRamseyer
    I haven't tested it in Win 10 yet but I don't see MS going backwards with NVMe and not allowing it to boot.

    Hi thank you for the article. If you ever reviewed a Mushkin scorpion deluxe could it be added to the chart? it has 2000 MB/s. the top one is a four 480-ssd raid on a card.

  • Arabian Knight
    NVMe Samsung SM951 is coming soon . and I think it will outperform this card ;) ..
  • atheus
    Maybe it's just me (I doubt it) — when I see an article on something like this the biggest question on my mind is what exactly am I going to get from going with something like this for a system build rather than 2.5" SATA SSD at less than half the price. In order to understand that, I've got to go dig out another article with 2.5" SSD stats and compare them there. Please consider putting the most prevalent main drive option of today into the charts next time you pop out a NVMe article.

    From what I have read about SSD speed, SATA3 is adequate for most people. A PCI-e storage or RAID will crush a 500Gb/s in benchmarks or workstation productivity apps pushing large file sizes. But for browsing, games and heavy use even Tom's tester said he could not "feel" the difference between a single SSD and a RAID that benchmarked much higher. Where I think NVMe shines is the ability to have a separate queue for each thread. I want the 400GB Intel 750 asap.

    Thank you Chris.

    What happens when you exceed the "70 GB Per Day" "endurance" ?
    At 1200 MB/s - that happens in one minute flat.
  • danlw
    What exactly is "Service Time"? I read the TomsHardware article "How We Test HDDs And SSDs", but I'm still fuzzy on "Service Time". Using Battlefield 3 / WoW, for example, are those times how long it takes for the game to load? (I'm pretty sure Wow loads for me much faster than 57 seconds for me) What I'd like to see is a "Load Time" chart. Will an Intel 750 boot windows and load games faster than the other SSDs in the chart? That's where the value is for me - reducing load times.

    It will be fine so long as you don't do it to often. So write once to the drive and then as little as possible for the life of the drive and it will last a long time.
  • Larry Litmanen
    What will be the boot time with this thing? 10 seconds? 5 seconds?

    Yes. On all these sites it seems new SSD reviews these days contain droves of benchmark results and in the final words or conclusions it states something as ambiguous as "this is really fast!" Most of us already own an SSD. How about we move on from the magnetic drive era and give us SSD enthusiasts a conclusion. For example I enjoy the "diminished returns" comments in the monthly best CPU articles.

    some people would be ok with just a 2.5" sata SSD. for people that are getting this, considering you are on a sata III ssd and you are trying to explain its just much better to have it over a sata I but they just wont budge because they dont think the difference is worth the cost, and they do have a point. sometimes its unnecessary to upgrade but we do it anyway.

    right now these pcie cost a lot, and it'll drop overtime, first it'll be 2.5" hopefully we see some tlc at 4TB a piece at 7 or 9.5mm, follow by these nvme ssd become available for majority of notebook.

    sata III compare to sata I is around 3 to 3.5x of sequential read/write performance, 4k increases by around 2-3x, and due to older gen SATA I ssd with older flash/controller/firmware etc, latency is about 2-3x higher. NVMe compare to sata III is about the same.

    Here's the Tom's review I've been waiting for! Great review!

    I am curious to know more about the "heavy conditioning" mentioned on the second-to-last page. It says that heavy conditioning the 750 changes the game entirely, but what exactly did achieving that entail?
  • danlw
    Toms, you may want to investigate boot times. I read a review on another site, and the Intel 750 took significantly longer to boot than standard SATA drives - on the order of 10+ seconds longer to boot. I wonder if this was a configuration issue, or something about NVMe is not conducive to fast boots?
