While roaming around at IDF, Ryan spotted a couple of new OCZ parts that were strangely absent from Flash Memory Summit:
You are looking at what is basically a Toshiba NVMe PCIe controller and flash, tuned for consumer applications and packaged/branded by OCZ. The only specific we know about it is that the scheduled release is in the November time frame. No specifics on performance yet but it should easily surpass any SATA SSD, but might fall short of the quad-controller-RAID RevoDrive 350 in sequentials.
As far as NVMe PCIe SSDs go, I'm happy to see more and more appearing on the market from every possible direction. It can only mean good things as it will push motherboard makers to perfect their UEFI boot compatibility sooner rather than later.
More to come on the RevoDrive 400 as November is just around the corner!

**Edit** There was some speculation about which controller was in this SSD. It has since been solved. Here's a shot of the top of the PCB:
Now lets compare that with a shot I caught at FMS 2015 last week:
...from the Phison booth. I hadn't wirtten up my Phison post yet but this new Kingston SSD is most certainly going to be using the Phison E7 controller. Here's the placard stating some high level specs:
We saw a draft copy of Kingston’s HyperX Predator at CES 2014. That demo unit was equipped with a SandForce 3700 series controller, but since SandForce never came through on that part, Kingston had to switch gears and introduce the HyperX Predator with a Marvell 88SS9293 controller. The Marvell part was very capable, and the HyperX Predator turned out to be an attractive and performant PCIe SSD. The one catch was that Marvell’s controller was only an AHCI part, while newer NVMe-based SSDs were quickly pushing the Predator down in our performance results.
Kingston’s solution is a newer generation PCIe SSD, this time equipped with NVMe:
We have very little additional information about this new part, though we can tell from the above image that the flash was provided by Toshiba (toggle mode). They also had Iometer running:
We were not sure of the exact workload being run, but those results are in line with the specs we saw listed on Silicon Motion’s SM2260, seen last week at Flash Memory Summit.
We’ll keep track of the development of this new part and hope to see it in a more disclosed form at CES 2016. Kingston's IDF 2015 press blast appears after the break.
Core and Interconnect
The Skylake architecture is Intel’s first to get a full release on the desktop in more than two years. While that might not seem like a long time in the grand scheme of technology, for our readers and viewers that is a noticeable change and shift from recent history that Intel has created with the tick-tock model of releases. Yes, Broadwell was released last year and was solid product, but Intel focused almost exclusively on the mobile platforms (notebooks and tablets) with it. Skylake will be much more ubiquitous and much more quickly than even Haswell.
Skylake represents Intel’s most scalable architecture to date. I don’t mean only frequency scaling, though that is an important part of this design, but rather in terms of market segment scaling. Thanks to brilliant engineering and design from Intel’s Israeli group Intel will be launching Skylake designs ranging from 4.5 watt TDP Core M solutions all the way up to the 91 watt desktop processors that we have already reviewed in the Core i7-6700K. That’s a range that we really haven’t seen before and in the past Intel has depended on the Atom architecture to make up ground on the lowest power platforms. While I don’t know for sure if Atom is finally trending towards the dodo once Skylake’s reign is fully implemented, it does make me wonder how much life is left there.
Scalability also refers to the package size – something that ensures that the designs the engineers created can actually be built and run in the platform segments they are targeting. Starting with the desktop designs for LGA platforms (DIY market) that fits on a 1400 mm2 design on the 91 watt TDP implementation Intel is scaling all the way down to 330 mm2 in a BGA1515 package for the 4.5 watt TDP designs. Only with a total product size like that can you hope to get Skylake in a form factor like the Compute Stick – which is exactly what Intel is doing. And note that the smaller packages require the inclusion of the platform IO chip as well, something that H- and S-series CPUs can depend on the motherboard to integrate.
Finally, scalability will also include performance scaling. Clearly the 4.5 watt part will not offer the user the same performance with the same goals as the 91 watt Core i7-6700K. The screen resolution, attached accessories and target applications allow Intel to be selective about how much power they require for each series of Skylake CPUs.
The fundamental design theory in Skylake is very similar to what exists today in Broadwell and Haswell with a handful of significant and hundreds of minor change that make Skylake a large step ahead of previous designs.
This slide from Julius Mandelblat, Intel Senior Principle Engineer, shows a higher level overview of the entirety of the consumer integration of Skylake. You can see that Intel’s goals included a bigger and wider core design, higher frequency, improved right architecture and fabric design and more options for eDRAM integration. Readers of PC Perspective will already know that Skylake supports both DDR3L and DDR4 memory technologies but the inclusion of the camera ISP is new information for us.

Just three weeks ago, we reported 3D XPoint Technology. This was a 2-layer stack of non-volatile memory that couples the data retention of NAND flash memory with speeds much closer to that of DRAM.
The big question at that time was less about the tech and more about its practical applications. Ryan is out covering IDF, and he just saw the first publically announced application by Intel:
Intel Optane Technology is Intel’s term for how they are going to incorporate XPoint memory dies into the devices we use today. They intend to start with datacenter storage and work their way down to ultrabooks, which means that XPoint must come in at a cost/GB closer to NAND than to DRAM. For those asking specific performance figures after our earlier announcement, here are a couple of performance comparisons between an SSD DC P3700 and a prototype SSD using XPoint:
At QD=8, the XPoint equipped prototype comes in at 5x the performance of the P3700. The bigger question is how about QD=1 performance, as XPoint is supposed to be far less latent than NAND?
Yes, you read that correctly, that’s 76k IOPS at QD=1. That means only issuing the SSD one command at a time, waiting for a reply, and only then issuing another command. Basically the worst case for SSD performance, as no commands are stacked up in the queue to enable parallelism to kick in and increase overall throughput. For comparison, SATA SSDs have a hard time maintaining that figure at their maximum queue depths of 32.
Exciting to see a follow-on announcement so quickly after the announcement of the technology itself, but remember that Intel did state ‘2016’ for these to start appearing, so don’t put off that SSD 750 purchase just yet.
More to follow as we continue our coverage of IDF 2015!
