Intel recently teased a bit of new information on its 3D XPoint DIMMs and launched its first public demonstration of the technology at the SAP Sapphire conference where SAP’s HANA in-memory data analytics software was shown working with the new “Intel persistent memory.” Slated to arrive in 2018, the new Intel DIMMs based on the 3D XPoint technology developed by Intel and Micron will work in systems alongside traditional DRAM to provide a pool of fast, low latency, and high density nonvolatile storage that is a middle ground between expensive DDR4 and cheaper NVMe SSDs and hard drives. When looking at the storage stack, the storage density increases along with latency as it gets further away from the CPU. The opposite is also true, as storage and memory gets closer to the processor, bandwidth increases, latency decreases, and costs increase per unit of storage. Intel is hoping to bridge the gap between system DRAM and PCI-E and SATA storage.
According to Intel, system RAM offers up 10 GB/s per channel and approximately 100 nanoseconds of latency. 3D XPoint DIMMs will offer 6 GB/s per channel and about 250 nanoseconds of latency. Below that is the 3D XPoint-based NVMe SSDs (e.g. Optane) on a PCI-E x4 bus where they max out the bandwidth of the bus at ~3.2 GB/s and 10 microseconds of latency. Intel claims that non XPoint NVMe NAND solid state drives have around 100 microsecomds of latency, and of course, it gets worse from there when you go to NAND-based SSDs or even hard drives hanging of the SATA bus.
Intel’s new XPoint DIMMs have persistent storage and will offer more capacity that will be possible and/or cost effective with DDR4 DRAM. In giving up some bandwidth and latency, enterprise users will be able to have a large pool of very fast storage for storing their databases and other latency and bandwidth sensitive workloads. Intel does note that there are security concerns with the XPoint DIMMs being nonvolatile in that an attacker with physical access could easily pull the DIMM and walk away with the data (it is at least theoretically possible to grab some data from RAM as well, but it will be much easier to grab the data from the XPoint sticks. Encryption and other security measures will need to be implemented to secure the data, both in use and at rest.
Interestingly, Intel is not positioning the XPoint DIMMs as a replacement for RAM, but instead as a supplement. RAM and XPoint DIMMs will be installed in different slots of the same system and the DDR4 RAM will be used for the OS and system critical applications while the XPoint pool of storage will be used for storing data that applications will work on much like a traditional RAM disk but without needing to load and save the data to a different medium for persistent storage and offering a lot more GBs for the money.
While XPoint is set to arrive next year along with Cascade Lake Xeons, it will likely be a couple of years before the technology takes off. Supporting it is going to require hardware and software support for the workstations and servers as well as developers willing to take advantage of it when writing their specialized applications. Fortunately, Intel started shipping the memory modules to its partners for testing earlier this year. It is an interesting technology and the DIMM solution and direct CPU interface will really let the 3D XPoint memory shine and reach its full potential. It will primarily be useful for the enterprise, scientific, and financial industries where there is a huge need for faster and lower latency storage that can accommodate massive (multiple terabyte+) data sets that continue to get larger and more complex. It is a technology that likely will not trickle down to consumers for a long time, but I will be ready when it does. In the meantime, I am eager to see what kinds of things it will enable the big data companies and researchers to do! Intel claims it will not only be useful at supporting massive in-memory databases and accelerating HPC workloads but for things like virtualization, private clouds, and software defined storage.
What are your thoughts on this new memory tier and the future of XPoint?

DigiTimes have heard about Intel's plans to reveal their next hardware devoted to AI functionality at Computex. Lake Crest is their deep learning hardware to support a new generation of neural network based computing and Knights Crest is the result of Intel's $350m purchase of the deep learning company Nervana which will be based on the familiar Xeon and Xeon Phi families of processor.
Jen-Hsun Huang, will deliver a keynote about NVIDIA's current AI projects along with their advancements in autonomous driving and deep learning, but we have not heard any juicy rumours about hardware announcements yet. Love him or hate him, Jen-Hsun's keynotes are never a waste of time to listen to.
"Nvidia and Intel are expected to unveil their latest plans on hardware platforms for artificial intelligence (AI) applications at Computex 2017, according to sources from the upstream supply chain."

For around $150 the MSI Krait Gaming motherboard is a decent deal for anyone building a computer around an LGA 1151 Intel processor. With three PCIe 3.0 x16 slots and an additional three PCIe 3.0 1x slots you have a lot of space to install additional cards. The storage is equally expansive with six SATA 6Gbps ports as well as two M.2 slots for newer generation SSDs and there are a total of 16 USB ports split between 3.0 and 2.0 including a Type-C port. The overclocking potential is also impressive, [H]ard|OCP easily configured their i7-7600K to run at 5.1GHz with memory at 3600MHz. Overall the board is a great mix of price and features and well worth considering.
"While it is generally the flagship motherboards that grab the most attention, it's the midrange offerings that see the most sales. MSI's Z270 Krait Gaming motherboard is one of those bread and butter type offerings. It has everything the gamer needs without the unnecessary and expensive fluff."

Please excuse the bit of self-promotion here. Oh, and disclaimer: Shrout Research and PC Perspective share management and ownership.
Based on testing done by Shrout Research and published in a paper this week, the introduction of Android applications on Chromebooks directly though the Play Store has added a new wrinkle into the platform selection decision. Android applications, unlike Chromebook native apps, have a heavy weight towards the Android phone and tablet ecosystem, with "defacto" optimization for the ARM-based processors and platforms that represent 98%+ of that market. As a result, there are some noticeable and noteworthy differences when running Android apps on Chromebooks powered by an ARM SoC and an Intel x86 SoC.
With that market dominance as common knowledge, all Android applications are developed targeting ARM hardware, for ARM processors. Compilers and performance profiling software has been built and perfected to improve the experience and efficiency of apps to run on ARMv7 (32-bit) and ARMv8 (64-bit) architectures. This brings to the consumer an improved overall experience, including better application compatibility and better performance.
Using a pair of Acer Chromebooks, the R11 based on the Intel Celeron N3060 and the R13 based on the MediaTek MT8173C, testing was done to compare the performance, loading times, and overall stability of various Android Play Store applications. A range of application categories were addressed including games, social, and productivity.
Through 19 tested Android apps we found that the ARM-powered R13 Chromebook performed better than the Intel-powered R11 Chromebook in 9 of them. In 8 of the apps tested, both platforms performed equally well. In 2 of the test applications, the Intel-powered system performed better (Snapchat and Google Maps).
The paper also touches on power consumption, and between these two systems, the ARM-based MediaTek SoC was using 11.5% less power to accomplish the same tasks.
Our testing indicates the Acer R13, using the ARM-powered processor, uses 11.5% less power on average in our 150 minutes of use through our education simulation. This is a significant margin and would indicate that with two systems equally configured, one with the MediaTek ARM processor and another with the Intel Celeron processor, the ARM-powered platform would get 11.5% additional usage time before requiring a charge. Based on typical Chromebook battery life (11 hours), the ARM system would see an additional 75 minutes of usability.
There is a lot more detail in the white paper on ShroutResearch.com, including a discussion about the impact that the addition of Android applications on Chromebooks might have for the market as whole:
...bringing a vast library of applications from the smart phone market to the Chromebook would create a combination of capabilities that would turn the computing spectrum sideways. This move alleviates the sustained notion that Chromebooks are connected-only devices and gives an instant collection of usable offline applications and tools to the market.

DigiTimes has posted an article covering the probable launch dates of AMD's new CPUs and GPUs as well as Intel's reaction to the release. Not all of these dates are confirmed but it is worth noting as these rumours are often close to those eventually announced. Naples will be the first, with the server chips launching at the end of June but that is just the start. July is the big month for AMD, with the lower end Ryzen 3 chips hitting the market as well as the newly announced 16 core Threadrippers and the X399 chipset. That will also be the month we see Vega's
Founders Frontier Edition graphics cards arrive.
Intel's Basin Falls platform; Skylake-X and Kaby Lake-X along with the associated X299 chipset are still scheduled for Computex reveal and a late June or early August release. Coffee Lake is getting pushed ahead however, it's launch has been moved up to late August instead of the beginning of next year.
Even with Intel's counters, AMD's balance sheet is likely to be looking better and better as the year goes on which is great news for everyone ... except perhaps Intel and NVIDIA.
"Demand for AMD's Ryzen 7- and Ryzen 5-series CPU products has continued rising, which may allow the chipmaker to narrow its losses to below US$50 million for the second quarter of 2017. With Intel also rumored to pay licensing fees to AMD for its GPUs, some market watchers believe AMD may turn profitable in the second quarter or in the third."

AMD has formally announced their EPYC CPUs. While Sebastian covered the product specifications, AMD has also released performance claims against a pair of Intel’s Broadwell-E Xeons. While Intel’s E5-2650 v4 processors have an MSRP of around $1170 USD, each, we don’t know how that price will compare to AMD’s offering. At first glance, pitting thirty two cores against two twelve-core chips seems a bit unfair, although it could end up being a very fair comparison if the prices align.

Patrick Moorhead, who was at the event, tweeted out photos of a benchmark where Ubuntu was compiled over GCC. It looks like EPYC completed in just 33.7s while the Broadwell-E chip took 37.2s (making AMD’s part ~9.5% faster). While this, again, stems from having a third more cores, this depends on how much AMD is going to charge you for them, versus Intel’s current pricing structure.

This one chip also has 128 PCIe lanes, rather than Intel’s 80 total lanes spread across two chips.
Application Profiling Tells the Story
It should come as no surprise to anyone that has been paying attention the last two months that the latest AMD Ryzen processors and architecture are getting a lot of attention. Ryzen 7 launched with a $499 part that bested the Intel $1000 CPU at heavily threaded applications and Ryzen 5 launched with great value as well, positioning a 6-core/12-thread CPU against quad-core parts from the competition. But part of the story that permeated through both the Ryzen 7 and the Ryzen 5 processor launches was the situation surrounding gaming performance, in particular 1080p gaming, and the surprising delta that we see in some games.
Our team has done quite a bit of research and testing on this topic. This included a detailed look at the first asserted reason for the performance gap, the Windows 10 scheduler. Our summary there was that the scheduler was working as expected and that minimal difference was seen when moving between different power modes. We also talked directly with AMD to find out its then current stance on the results, backing up our claims on the scheduler and presented a better outlook for gaming going forward. When AMD wanted to test a new custom Windows 10 power profile to help improve performance in some cases, we took part in that too. In late March we saw the first gaming performance update occur courtesy of Ashes of the Singularity: Escalation where an engine update to utilize more threads resulted in as much as 31% average frame increase.
As a part of that dissection of the Windows 10 scheduler story, we also discovered interesting data about the CCX construction and how the two modules on the 1800X communicated. The result was significantly longer thread to thread latencies than we had seen in any platform before and it was because of the fabric implementation that AMD integrated with the Zen architecture.
This has led me down another hole recently, wondering if we could further compartmentalize the gaming performance of the Ryzen processors using memory latency. As I showed in my Ryzen 5 review, memory frequency and throughput directly correlates to gaming performance improvements, in the order of 14% in some cases. But what about looking solely at memory latency alone?

Tagged: rumour, Intel, Core i9
A two part rumour circulating the internet this morning, involving new processors and a new naming convention. The leak that The Inquirer posted about this morning reveals six new Intel processors, two Kaby Lake-X processors with four cores running at a base clock of 4GHz or 4.3GHz depending on the model and TDPs of 112W. More interesting are the new Kaby Lake-X processors which are referred to as Core i9 models, running from an i9-7800X @ 3.6GHz base to the i9-7920X which runs at an unspecified speed. All will have four times the L2 cache of the current i7-7700K and Turbo 2.0 Boost Max to increase the frequency of several cores at once as well as Turbo Boost 3.0 for single-threaded workloads.
It will be interesting to see if the Core i7 family continues as an upper middle class of processors with the i9 family replacing it's current standing or if the new processors will be priced like high end Xeons.
"The slide, which an Anandtech forum member claims is an internal Intel document, provides details of four new Skylake-X processors and two Kaby Lake-X CPUs. The Skylake-X processors are described as Core i9, and if the leak is genuinely - and that's a fairly big if - the new Core i9s will replace Core i7s as Intel's top-of the-pile PC chipset range."

Microsoft has announced their new Surface Laptop, which notably leaked just yesterday, but the surprising part was not the hardware at all - however sleek and impressive it might be. Yes, it seems I spoke too soon with the Windows 10 S news, as this consumer (I assume) product is shipping with that new version of the OS which only allows apps to be installed from the Windows Store.
As to the hardware, it is milled from a block of aluminum (as shown in a very Apple-like video) and the heat pipes for the processor are milled into the bottom case to help make this so thin, but the laptop will undoubtedly feel warm to the touch during use (a fact which was mentioned on stage as a positive thing). The palmrest/keyboard is coated in a fabric material called Alcantara, rather than being bare metal and plastic. The combination of warmth (literally) and the fabric surface is supposed to make the new laptop feel very friendly, as the narrative went.
Thankfully (in my opinion, anyway) the bizarre flexible hinge of the prior Surface laptop is gone in favor of a conventional one - and with it the air gap from he previous design. Among the features mentioned for this new Surface were its PixelSense screen, which is the “thinnest LCD touch panel ever in a laptop”, and a very impressive 14.5 hour battery life. The standby power consumption was described as effectively zero, which suggests that a suspend state of some kind is standard to prevent drain when not in use. rather than a low-power sleep.

Microsoft stated that two versions (Intel Core i5 and Core i7) will be available for pre-order beginning today, with the Core i5 model starting at $999. (Pricing on the Core i7 version was not mentioned.)
Windows Central has posted specs for the new machines, reproduced below:
- Display: 13.5-inch Pixel Sense display, 10 point multi-touch
- Display Resolution: 2256 x 1504, at 201 ppi, Aspect Ratio: 3:2

- Memory: 4GB, 8GB or 16GB RAM
- Graphics: i5: Intel HD graphics 620, i7: Intel Iris Plus Graphics 640
- Front Camera: 720p, Windows Hello face authentication

I will briefly editorialize here to mention the Windows 10 S problem here. That limitation might make sense for education, if Microsoft is providing a suite of apps that make sense for a school, but consumers will undoubtedly want more flexibility from their own devices. This is less consumer-friendly than even the Starter Edition of Windows from the past, which limited the number of running applications but not their provenance.
