Review: The PNY PrevailPro mobile workstation

By Mike McCarthy

PNY, a company best known in the media and entertainment industry as the manufacturer of Nvidia’s Quadro line of professional graphics cards, is now offering a powerful mobile workstation. While PNY makes a variety of other products, mostly centered around memory and graphics cards, the PrevailPro is their first move into offering complete systems.

Let’s take a look at what’s inside. The PrevailPro is based on Intel’s 7th generation Core i7 7700HQ Quad-Core Hyperthreaded CPU, running at 2.8-3.8GHz. It has an HM175 chipset and 32GB of dual-channel DDR4 RAM. At less than ¾-inch thick and 4.8 pounds, it also has an SD card slot, fingerprint reader, five USB ports, Gigabit Ethernet, Intel 8265 WiFi, and audio I/O. It might not be the lightest 15-inch laptop, but it is one of the most powerful. At 107 cubic inches, it has half the volume of my 17-inch Lenovo P71.

The model I am reviewing is their top option, with a 512GB NVMe SSD, as well as a 2TB HDD for storage. The display is a 15.6-inch UHD panel, driven by the headline feature, a Quadro P4000 GPU in Max-Q configuration. With 1792 CUDA cores, and 8GB of GDDR memory, the GPU retains 80% of the power of the desktop version of the P4000, at 4.4 TFlops. Someone I showed the system to joked that it was a PNY Quadro graphics card with a screen, which isn’t necessarily inaccurate. The Nvidia Pascal-based Quadro P4000 Max-Q GPU is the key unique feature of the product, being the only system I am aware of in its class — 15-inch workstations — with that much graphics horsepower.

Display Connectivity
This top-end PrevailPro system is ProVR certified by Nvidia and comes with a full complement of ports, offering more display options than any other system its size. It can drive three external 4K displays plus its attached UHD panel, an 8K monitor at 60Hz or anything in between. I originally requested to review this unit when it was announced last fall because I was working on a number of Barco Escape three-screen cinema projects. The system’s set of display outputs would allow me to natively drive the three TVs or projectors required for live editing and playback at a theater, without having to lug my full-sized workstation to the site. This is less of an issue now that the Escape format has been discontinued, but there are many other applications that involve multi-screen content creation, usually related to advertising as opposed to cinema.

I had also been looking for a more portable device to drive my 8K monitor — I wanted to do some on-set tests, reviewing footage from 8K cameras, without dragging my 50-pound workstation around with me — even my 17-inch P71 didn’t support it. Its DisplayPort connection is limited to Version 1.2, due to being attached to the Intel side of the hybrid graphics system. Dell’s Precision mobile workstations can drive their 8K display at 30Hz, but none of the other major manufacturers have implemented DisplayPort 1.3, favoring the power savings of using Intel’s 1.2 port in the chipset. The PrevailPro by comparison has dual mini-DisplayPort 01.3 ports, connected directly to the Nvidia GPU, which can be used together to drive an 8K monitor at 60Hz for the ultimate high-res viewing experience. It also has an HDMI 2.0 port supporting 4Kp60 with HDCP to connect your 4K TV.

It can connect three external displays, or a fourth with MST if you turn off the integrated panel. The one feature that is missing is Thunderbolt, which may be related to the DisplayPort issue. (Thunderbolt 3 was officially limited to DisplayPort 1.2) This doesn’t affect me personally, and USB 3.1 has much of the same functionality, but it will be an issue for many users in the M&E space — it limits its flexibility.

User Experience
The integrated display is a UHD LCD panel with a matte finish. It seems middle of the line. There is nothing wrong with it, and it appears to be accurate, but it doesn’t really pop the way some nicer displays do, possibly due to the blacks not being as dark as they could be.

The audio performance is not too impressive either. The speaker located at the top of the keyboard aren’t very loud, even at maximum volume, and they occasionally crackle a bit. This is probably the system’s most serious deficiency, although a decent pair of headphones can improve that experience significantly. The keyboard is well laid out, and felt natural to use, and the trackpad worked great for me. Switching between laptops frequently, I sometimes have difficulty adjusting to changes in the function and arrow key positioning, but everything was where my fingers expected them to be.

Performance wise, I am not comparing it to other 15-inch laptops, because I don’t have any to test it against, and that is not the point of this article. The users who need this kind of performance have previously been limited to 17-inch systems, and this one might allow them to lighten their load — more portable without sacrificing much performance. I will be comparing it to my 17-inch and 13-inch laptops, for context, as well as my 20-core Dell workstation.

Storage Performance
First off, with synthetic benchmarks, the SSD reports 1400MB/s write and 2000MB/s read performance, but the write is throttled to half of that over sustained periods. This is slower than some new SSDs, but probably sufficient because without Thunderbolt there is no way to feed the system data any faster than that. (USB 3.1 tops out around 800MB/s in the real world.)

The read speed allowed me to playback 6K DPX files in Adobe Premiere, and that is nothing to scoff at. The HDD tops out at 125MB/s as should be expected for a 2.5-inch SATA drive, so it will perform just like any other system. The spinning disk seems out of place in a device like this, where a second M.2 slot would have allowed the same capacity, at higher speeds, with size and power savings.

Here are its Cinebench scores, compared to my other systems:
System OpenGL CPU
PNY PrevailPro (P4000) 109.94 738
Lenovo P71 (P5000) 153.34 859
Dell 7910 Desktop (P6000) 179.98 3060Aorus X3 Plus (GF870) 47.00 520

The P4000 is a VR-certified solution, so I hooked up my Lenovo Explorer HMD and tried editing some 360 video in Premiere Pro 12.1. Everything works as expected, and I was able to get my GoPro Fusion footage to play back 3Kp60 at full resolution, and 5Kp30 at half resolution. Playing back exported clips in WMR worked in full resolution, even at 5K.

8K Playback
One of the unique features of this system is its support for an 8K display. Now, that makes for an awfully nice UI monitor, but most people buying it to drive an 8K display will probably want to view 8K content on it. To that end, 8K playback was one of the first things I tested. Within Premiere, DNxHR-LB files were the only ones I could get to play without dropping frames at full resolution, and even then only when they were scope aspect ratio. The fewer pixels to process due to the letterboxing works in its favor. All of the other options wouldn’t playback at full resolution, which defeats the purpose of an 8K display. The Windows 10 media player did playback 8K HEVC files at full resolution without issue, due to the hardware decoder on the Quadro GPU, which explicitly supports 8K playback. So that is probably the best way to experience 8K media on a system like this.

Now obviously 8K is pushing our luck with a laptop in the first place. My 6K Red files play back at quarter res, and most of my other 4K and 6K test assets play smoothly. I rendered a complex 5K comp in Adobe After Effects, and at 28 minutes, it was four minutes slower than my larger 17-inch system, and twice as fast as my 13-inch gaming notebook. Encoding a 10-minute file in DCP-O-Matic took 47 minutes in 2K, and 189 minutes in 4K, which is 15% slower than my 17-inch laptop.

Conclusion
The new 15-inch PrevailPro is not as fast as my huge 17-inch P71, as to be expected, but it is close in most tests, and many users would never notice the difference. It supports 8K monitors and takes up half the space in my bag. It blows my 13-inch gaming notebook out of the water and does many media tasks just as fast as my desktop workstation. It seems like an ideal choice for a power user who needs strong graphics performance but doesn’t want to lug around a 17-inch monster of a system.

The steps to improve it would be the addition of Thunderbolt support, better speakers, and an upgrade to Intel’s new 8th Gen CPUs. If I was still working on multi-screen theatrical projects, this would be the perfect system for taking my projects with me — same if I was working in VR more. I believe the configuration I tested has an MSRP of $4,500, but I find it online for around $4100. So it is clearly not the cheap option, but it is one of the most powerful 15-inch laptops available, especially if your processing needs are GPU intense. It is a well-balanced solution, for demanding users who need performance, but want to limit size and weight.

Review: HP’s zBook x2 mobile workstation

By Brady Betzel

There are a lot of laptops and tablets on the market these days that can seemingly power a SpaceX Falcon 9 rocket launch and landing. If you work in media and entertainment like I do, these days you might even be asked to edit and color correct that Falcon 9 footage that could have been filmed in some insane resolution like 8K.

So how do you edit that footage on the go? You need to find the most powerful mobile solution on the market. In my mind there are only a few that can power editing 8K footage (even if the footage is transcoded into manageable ProRes proxies). There is Razer, which offers a 4K/UHD “gaming” laptop with its Razer Blade Pro. It sports a high-end Nvidia GTX 1060 GPU and i7 processor; Dell’s high-end Precision 7720 mobile workstation allows for a high-end Quadro GPU; and HP offers high-quality mobile workstations via its zBook line.

For this review, I am focusing on the transforming HP zBook x2 mobile workstation, complete with an Intel Core i7 CPU, 32GB memory, Nvidia Quadro and much more.

The zBook x2 allows you to go laptop-style to tablet by removing the keyboard. If you’ve ever used a Wacom Cintiq mobile tablet, you’ve likely enjoyed the matte finish of the display, as well as the ability to draw directly on screen with a stylus. Well, the zBook x2 is a full touchscreen as well as stylus-enabled matte surface compatible with HP’s own battery-less pen. The pen from HP is based off of Wacom’s Electro Magnetic Resonance technology, which essentially allows for cable- and battery-free pens.

In addition, the display bezel has 12 buttons that are programmable for apps like Adobe’s Creative Cloud. For those wondering, HP partnered with Adobe when designing the x2, so you will notice that Creative Cloud comes pre-installed on the system, and the quick access buttons around the bezel are already programmed for use in Adobe’s apps. However, they don’t give you a free subscription with purchase — Hey, HP, this would be a nice touch. Just a suggestion.

Digging In
I was sent the top-of-the-line version of the zBook x2, complete with a DreamColor UHD touchscreen display. Here are the specs under the hood:

– Windows 10 64-bit
– Intel Core i7 8650 (Quad Core — 8th gen)
– 4K UHD DreamColor Touch with anti-glare
– 32GB (2×16 GB) DDR4 2133 memory
– Nvidia Quadro M620 (2GB)
– 512GB HP Z-Turbo Drive PCIe
– 70Whr fast charging battery
– Intel vPro WLAN
– Backlit Bluetooth Keyboard
– Fingerprint reader
– One- or three-year warranty, including the battery
– Two Thunderbolt 3 ports
– HDMI 1.4 port
– USB 3.0 charging port
– SD card slot
– Fingerprint reader
– Headset/microphone port
– External volume controls

The exterior hardware specs are as impressive as the technical specs. I’ve got to be honest, when I first received the x2, I was put off by the sharp edged-octagon design. I’m so used to either square shaped tablets or rounded edges, so the octagon-edged sides were a little strange. After using it for a month, I got used to how sturdy and well built this machine is. I kind of miss the octagon shape now that I had to ship the x2 back to HP.

In addition, the zBook x2 I received weighed in at around 5lbs (with the bluetooth keyboard attached), which isn’t really lightweight. Part of that weight is the indestructible-feeling magnesium and aluminum casing that surrounds the x2’s internal components.

I’ve reviewed a few of these stylus-based workstations before, such as Microsoft’s Surface Pro and Wacom’s mobile Cintiq offering, and they each have their positives and negatives. One thing that consistently sticks out to me is the kickstand used to prop these machines up. When you use a stylus on a tablet you will have a height and angle you like to work at. Some tablets have a few specified heights like the Wacom offering. The Surface Pro has a somewhat limited angle, but the zBook x2 has the strongest and best working built-in stand that I have used. It is sturdy when working in apps, like Adobe Photoshop, with the stylus.

HP’s Wacom-infused stylus is very lightweight. I personally like a stylus that is a little hefty, like the Wacom Pro Pen, but don’t get me wrong, HP’s pen works well. The pen has a similar pressure sensitivity to the Wacom’s pens many multimedia pros are used to at 4,096 levels and includes tilt sensitivity. When using tablets, palm rejection is a very important feature, and the x2 has excellent palm rejection. HP’s fact sheets and website all have different information on whether the pen is included with the x2 or not, but when ordering it looks like it is bundled with your purchase. As it should be).

One final note on the build quality of HP’s zBook x2: the detachable Bluetooth keyboard is excellent. The keyboard not only acts like a full-sized keyboard, complete with numerical keypad (a favorite of mine when typing in specific timecodes), but it also folds up to protect the screen when not in use.

If you are looking at the zBook x2 to purchase, you are probably also comparing it to a Microsoft Surface Pro, a Wacom Cintiq mobile computer and maybe an iPad Pro. In my opinion, there is no contest. Te x2 wins hands down. However, you are also going to be paying a lot more for it. For instance, the x2 can be purchased with the latest Intel 8th gen i7 processors, an Nvidia Quadro GPU built into the tablet —not the keyboard like on the Microsoft Surface Book systems — it has the ability to be packed with 32GB of RAM as opposed to 16GB in all other tablets. And most importantly, in my opinion, this system offers a color-accurate UHD 10-bit-HP DreamColor display. As I said, it is definitely the beefiest mobile workstation/tablet that you will find out there, but will cost you.

One of my favorite practices that HP is starting to standardize among its mobile workstations is the use of quick charging, where you can charge 50% of your battery in a half an hour and the rest over a few more hours. I can’t tell you how handy this is when you are running around all day and don’t have four hours to charge your computer between appointments. When running apps like Blackmagic’s Resolve 14.3 with UHD video, you can drain the battery fast — something like four hours — but being able to quickly charge back up to 50% is a lifesaver in a lot of circumstances.

In the real world, I use my mobile workstation/tablets all the time. I surf the web, listen to music, edit in Adobe Premiere Pro or color correct in Resolve. This means my systems have to have some high-end processors to keep up. The HP zBook x2 is a great addition to your workstation lineup when you need to take your work on the road and not lose any features, like the HP DreamColor display with 100% Adobe RGB color accuracy. While it’s not a truly calibrated work monitor, DreamColor displays will, at the very least, give you a common calibration among all DreamColor monitors that you can rely on for color critical jobs on the run. In addition, DreamColor displays can display different color spaces like BT. 709, DCI-P3 and more.

Putting it to the Test
To test the x2, I ran a few tests using one of the free clips that Red offers to download from: http://www.red.com/sample-r3d-files. It is the Red One Mysterium clip with a resolution of 4096×2304 and runs at 29.97fps. For a mobile workstation this is a pretty hefty clip to run in Resolve or Premiere. In Premiere, the Red clip would play at realtime when dumbed down to half quality. Half quality isn’t bad to work in, but when spending $3,500 I would like to work in a better-quality Red files. Maybe the technology will be there in a year.

If you are into the whole offline/online workflow (a.k.a. proxy workflow — a.k.a. transcoding to a interframe codec like DNxHR or ProRes — then you will be able to play down the full 4K clip when transcoding to something like DNxHR HQ. Unfortunately, I couldn’t get a 10-bit DNxHR HQX clip to play at realtime, and with the sweet 10-bit display that could have been a welcome success. To test exporting speed I trimmed the R3D file (still raw Red) to 10 seconds and exported it as a DNxHR HQX 10-bit QuickTime (in the files native resolution and frame rate) and highly compressed H.264 at around 10,000mb/s.

The DNxHR HQX 10-bit QuickTime took 1 minute and 25 seconds to export. I then added a 110% resize and a color grade to really make sure the Quadro GPU kicked in, and unfortunately the export failed. I tried multiple times with different Lumetri color grades and all of them failed, probably a sweet bug.

Next, I exported an uncolored 10,000mb/s H.264 MP4 (a clip perfect for YouTube) in 2 minutes and 41 seconds. I then resized the clip to 110% and performed a color grade using the Lumetri tools inside of Premiere Pro. The MP4 exported in 1 minute and 30 seconds. This was pretty incredible and really showed just how important that Nvidia Quadro M620 with 2GB of memory is. And while things like resizing and color correcting will make sure your GPU kicks in to help, the HP zBook x2 was relatively quiet with the active cooling fan system that kicks all of the hot air up and out of the magnesium case.

Inside of Resolve 14.3, I performed the same tests on the same Red clip. I was able to play the Red clip at about 16fps in 1/16 debayer quality in realtime. Not great, but for a mobile tablet workstation, maybe it’s ok, although I would expect more from a workstation. When exporting the DNxHR HQX 10-bit QuickTime took 2 minutes and the same clip resized to 110% and color graded also took 2 minutes. The H.264 took 2 minutes and 33 seconds without any color grading and resizing, but it also took 2 minutes and 33 seconds when resized 110% and color graded. I had all caching and performance modes disabled when performing these tests. I would have thought Resolve would have performed better than Premiere Pro, but in this case Adobe wins.

As a bonus, I happen to have Fusion, GoPro’s 360 video camera, and ran it through Fusion Studio, GoPro’s stitching and exporting software. Keep in mind 360 video is a huge resource hog that takes lots of time to process. The 30-second test clip I exported in flat color, with image stabilization applied, took an hour to export. The resulting file was a 1.5GB – 4992×2496 4:2:2 Cineform 10-bit YUV QuickTime with Ambisonic audio. That’s a big and long render in my opinion, although it will also take a long time on many computers.

Summing up
In the end, the HP zBook x2 is a high-end mobile workstation that doubles as a stylus-based drawing tablet designed to be used in apps like Photoshop and even video editing apps like Premiere Pro.

The x2 is profoundly sturdy with some high-end components, like the Intel i7 8th gen processor, Nvidia Quadro M620 GPU, 4K/UHD HP DreamColor touchscreen display and 32GB of RAM.

But along with these high-end components comes a high price: the setup in this review retails for around $3,500, which is not cheap. But for a system that is designed to be run 24 hours a day 365 days a year, it might be the investment you need to make.

Do you want to use the table at the office when connected to a Thunderbolt 3 dock while also powering a 4K display? The x2 is the only mobile table workstation that will do this at the moment. If I had any criticisms of the HP zBook x2 it would be the high cost and the terrible speakers. HP touts the Bang & Olufsen speakers on the x2, but they are not good. My Samsung Galaxy S8+ has better speakers.

So whether you are looking to color correct on the road or have a Wacom-style table at the office, the HP zBook x2 is a monster that HP has certified with companies like Adobe using their Independent Software Vendor verifications to ensure your drivers and software will work as well as possible.

HP intros new versions of its mobile and tower workstations

By Mike McCarthy

Last week I got the opportunity to attend HP’s big workstation launch event in Fort Collins, Colorado. HP is releasing new versions of its ZBook mobile workstations and desktop Z workstation towers. I also got to tour their labs and see behind the curtain at the development and testing process.

New “G2” versions of last year’s HP ZBook 15 and ZBook 17 will be available later this month. Both models sport the newest “Haswell” architecture-based Intel CPUs, new AMD and Nvidia GPU cards and M.2 storage options. HP has branded their PCIe-based flash storage solution as the “Z-Turbo Drive,” and it is available in their new ZBooks and workstations. Removing the SATA interface bottleneck greatly improves maximum read and write speeds on the new flash Continue reading
