Over at [H]ard|OCP is a look at the current market and the resurgence of competition which we are currently enjoying.  As opposed to several pages of detailed benchmarks, the article focuses on the various feature sets that AMD and Intel currently offer and the effect it has on your current system choices.  They consider a wide variety of aspects, from the quality and quantity of PCIe lanes offered on X399 and X299 platforms through to the very different choices the companies have made when it comes to PCIe storage and RAID.  It has been quite a while since we have seen the competition between AMD and Intel heat up to these levels and it is wonderful to see.

"I’ve spent quite a bit of time with AMD’s Threadripper and X399 chipset and I thought I’d give our readers my impression of it and talk about the platform as well as giving interested consumers a general overview of the platform and what it has to offer. We compare it to Intel’s HEDT platform and give our take on this match up."

Intel Quad RAID-0 Optane Memory 32GB Bootable Without VROC Key!

Subject: Storage | October 4, 2017 - 09:24 PM |
Tagged: x299, VROC, skylake-x, RAID-0, Optane, Intel, bootable, boot

We've been playing around a bit with Intel VROC lately. This new tech lets you create a RAID of NVMe SSDs connected directly to newer Intel Skylake-X CPUs, without the assistance of any additional chipset or other RAID controlling hardware on the X299 platform. While the technology is not fully rolled out, we did manage to get it working and test a few different array types as a secondary volume. One of the pieces of conflicting info we had been trying to clear up was can you boot from a VROC array without the currently unobtanium VROC key...

VROC-booted-3.jpeg

Well, it seems that question has been answered with our own tinkering. While there was absolutely no indication in the BIOS that our Optane Memory quad RAID-0 was bootable (the array is configurable but does not appear in the bootable devices list), I'm sitting here looking at Windows installed directly to a VROC array!

Important relevant screenshots below:

VROC-booted-1-.png

VROC-booted-2.png

For the moment this will only work with Intel SSDs, but Intel's VROC FAQ states that 'selected third-party SSDs' will be supported, but is unclear if that includes bootability (future support changes would come as BIOS updates since they must be applied at the CPU level). We're still digging into VROC as well as AMD's RAID implementation. Much more to follow, so stay tuned!

Manufacturer: PC Perspective

Introduction

Introduction

We've been hearing about Intel's VROC (NVMe RAID) technology for a few months now. ASUS started slipping clues in with their X299 motherboard releases starting back in May. The idea was very exciting, as prior NVMe RAID implementations on Z170 and Z270 platforms were bottlenecked by the chipset's PCIe 3.0 x4 DMI link to the CPU, and they also had to trade away SATA ports for M.2 PCIe lanes in order to accomplish the feat. X99 motherboards supported SATA RAID and even sported four additional ports, but they were left out of NVMe bootable RAID altogether. It would be foolish of Intel to launch a successor to their higher end workstation-class platform without a feature available in two (soon to be three) generations of their consumer platform.

To get a grip on what VROC is all about, lets set up some context with a few slides:

slide-1.png

First, we have a slide laying out what the acronyms mean:

  • VROC = Virtual RAID on CPU
  • VMD = Volume Management Device

What's a VMD you say?

slide-2.png

...so the VMD is extra logic present on Intel Skylake-SP CPUs, which enables the processor to group up to 16 lanes of storage (4x4) into a single PCIe storage domain. There are three VMD controllers per CPU.

slide-3.png

VROC is the next logical step, and takes things a bit further. While boot support is restricted to within a single VMD, PCIe switches can be added downstream to create a bootable RAID possibly exceeding 4 SSDs. So long as the array need not be bootable, VROC enables spanning across multiple VMDs and even across CPUs!

Assembling the Missing Pieces

Unlike prior Intel storage technology launches, the VROC launch has been piecemeal at best and contradictory at worst. We initially heard that VROC would only support Intel SSDs, but Intel later published a FAQ that stated 'selected third-party SSDs' would also be supported. One thing they have remained steadfast on is the requirement for a hardware key to unlock RAID-1 and RAID-5 modes - a seemingly silly requirement given their consumer chipset supports bootable RAID-0,1,5 without any key requirement (and VROC only supports one additional SSD over Z170/Z270/Z370, which can boot from 3-drive arrays).

On the 'piecemeal' topic, we need three things for VROC to work:

  • BIOS support for enabling VMD Domains for select groups of PCIe lanes.
  • Hardware for connecting a group of NVMe SSDs to that group of PCIe lanes.
  • A driver for OS mounting and managing of the array.

Let's run down this list and see what is currently available:

BIOS support?

170927121509.png

Check. Hardware for connecting multiple drives to the configured set of lanes?

170927-165526.jpg

Check (960 PRO pic here). Note that the ASUS Hyper M.2 X16 Card will only work on motherboards supporting PCIe bifurcation, which allows the CPU to split PCIe lanes into subgroups without the need of a PLX chip. You can see two bifurcated modes in the above screenshot - one intended for VMD/VROC, while the other (data) selection enables bifurcation without enabling the VMD controller. This option presents the four SSDs to the OS without the need of any special driver.

With the above installed, and the slot configured for VROC in the BIOS, we are greeted by the expected disappointing result:

VROC-2.png

Now for that pesky driver. After a bit of digging around the dark corners of the internet:

VROC-11.png

Check! (well, that's what it looked like after I rapidly clicked my way through the array creation)

G.Skill Readies DDR4-4400 Kits for Intel's X299 HEDT Platform

Subject: Memory | June 29, 2017 - 02:03 PM |
Tagged: x299, trident z, samsung 8Gb, overclocking, G.Skill, ddr4

G.Skill recently announced new DDR4 memory kits for the Intel X299 HEDT platform. The new kits include a dual channel DDR4 4400 MHz kit for Kaby Lake X and a quad channel DDR4 4200 MHz kit for Skylake X. The dual channel kit is available under the company’s Trident Z RGB and Trident Z Black brands depending on whether you want RGB lighting or simple black heatspreaders. The quad channel DDR4-4200 kit is only available in non-RGB Trident Z modules.

According to G.Skill, all of the new memory kits use Samsung 8Gb dies and feature CAS latencies of 19-19-19-39. The quad channel 4200 MHz DDR4 modules need 1.40V to hit those specifications, and while it is not yet known what the higher clocked dual channel DDR4 4400 MHz kits need to hit CL19 timings I would presume they need a bit more.

The new kits will be available in an 8GB x 2 (16GB) 4400 MHz kit and up to 64 GB (8GB x 8) 4200 MHz kits. Pricing has not yet been announced, but the new RAM kits should be available soon. While Intel processors do not get as much of a boost from increased memory speeds as AMD’s APUs and Ryzen CPUs do, there are still noticeable gains to be had with faster memory though gamers should still prioritize graphics cards and processors over memory when picking parts for a budget build.

Note that since these kits are using Samsung 8Gb ICs, they also have a good chance of working with Ryzen, but check with your motherboard manufacturer and reviews before ponying up the cash.

Tagged: 7900x, Core i9, Intel, skylake-x, x299

The Tech Report recently wrapped up the first part of their review of Intel's new Core i9-7900X, focusing on its effectiveness in production machine.  Their benchmarks cover a variety of scientific tasks such as PhotoWorxx, FPU Julia and Mandel as well as creativity benchmarks like picCOLOR, DAWBench DSP 2017 and STARS Euler3D.  During their testing they saw the same peaks in power consumption as Ryan did in his review, 253W under a full Blender load.  Their follow up review will focus on the new chips gaming prowess, for now you should take a look at how your i9-7900X will perform for you when you are not playing around.

Specifications and Design

Intel is at an important crossroads for its consumer product lines. Long accused of ignoring the gaming and enthusiast markets, focusing instead on laptops and smartphones/tablets at the direct expense of the DIY user, Intel had raised prices and only shown limited ability to increase per-die performance over a fairly extended period. The release of the AMD Ryzen processor, along with the pending release of the Threadripper product line with up to 16 cores, has moved Intel into a higher gear; they are more prepared to increase features, performance, and lower prices now.

We have already talked about the majority of the specifications, pricing, and feature changes of the Core i9/Core i7 lineup with the Skylake-X designation, but it is worth including them here, again, in our review of the Core i9-7900X for reference purposes.

There is a lot to take in here. The three most interesting points are that, one, Intel plans to one-up AMD Threadripper by offering an 18-core processor. Two, which is potentially more interesting, is that it also wants to change the perception of the X299-class platform by offering lower price, lower core count CPUs like the quad-core, non-HyperThreaded Core i5-7640X. Third, we also see the first ever branding of Core i9.

Intel only provided detailed specifications up to the Core i9-7900X, which is a 10-core / 20-thread processor that has a base clock of 3.3 GHz and a Turbo peak of 4.5 GHz (using the new Turbo Boost Max Technology 3.0). It sports 13.75MB of cache thanks to an updated cache configuration, it includes 44 lanes of PCIe 3.0, an increase of 4 lanes over Broadwell-E, it has quad-channel DDR4 memory up to 2666 MHz and it has a 140 watt TDP. The new LGA2066 socket will be utilized. Pricing for this CPU is set at $999, which is interesting for a couple of reasons. First, it is $700 less than the starting MSRP of the 10c/20t Core i7-6950X from one year ago; obviously a big plus. However, there is quite a ways UP the stack, with the 18c/36t Core i9-7980XE coming in at a cool $1999.

Price (Launch) $999 $1700 $339

The next CPU down the stack is compelling as well. The Core i7-7820X is the new 8-core / 16-thread HEDT option from Intel, with similar clock speeds to the 10-core above it (save the higher base clock). It has 11MB of L3 cache, 28-lanes of PCI Express (4 higher than Broadwell-E) but has a $599 price tag. Compared to the 8-core 6900K, that is ~$400 lower, while the new Skylake-X part iteration includes a 700 MHz clock speed advantage. That’s huge, and is a direct attack on the AMD Ryzen 7 1800X, which sells for $499 today and cut Intel off at the knees this March. In fact, the base clock of the Core i7-7820X is only 100 MHz lower than the maximum Turbo Boost clock of the Core i7-6900K!

It is worth noting the performance gap between the 7820X and the 7900X. That $400 gap seems huge and out of place when compared to the deltas in the rest of the stack that never exceed $300 (and that is at the top two slots). Intel is clearly concerned about the Ryzen 7 1800X and making sure it has options to compete at that point (and below) but feels less threatened by the upcoming Threadripper CPUs. Pricing out the 10+ core CPUs today, without knowing what AMD is going to do for that, is a risk and could put Intel in the same position as it was in with the Ryzen 7 release.
