HP Z840 Workstation High-End Desktop

The HP Z840 Workstation is a high-end workstation desktop made for hypercritical engineering and scientific tasks on projects that could potentially affect thousands, if not millions, of people. Its dual octo-core Intel Xeon processors and Nvidia Quadro K4200 graphics are equipped to help you evaluate multiple scenarios, whether you are trying to differentiate between natural gas and crude oil pockets 10,000 meters below a raging sea, actively rendering and comparing images from a series of MRI scans, or seeing how a thunderstorm will disrupt the laminar flow over an airliner’s wing. The Z840 has the power to perform all these tasks (and more), and is our new Editors’ Choice for dual-processor workstations.

In the past five years the aesthetic of the business workstation has changed dramatically from the lackluster copy-paste machine to something more appealing to the eye. The HP Z840 has the look of a modern, simple, and sleek tower. The sides feature a gorgeous brushed aluminum with HP printed into the metal. This is surrounded by an incognito black bezel frame. On top, the HP Z840 has two handles for carrying, which you will need because the machine can get heavy depending on customization.

The HP Z840 Workstation features the latest generation of Intel Xeon processors, supporting a range of chips, from the Intel Xeon E5-2603 v3 to Intel Xeon E5-2699 v3 processor. Not only can the HP Z840 be configured to take the Xeon E5-2699 v3 18 core 2.30 GHz processor, but it can be configured for two of them. To put this into perspective, when adding on the Xeon E5-2699 into the HP Z840.

RAM can also be customized from anywhere between 4GB DDR4-2133 RAM to the max that the HP Z840 can hold which is 512GB DDR4-2133 RAM. The HP Z840 comes packed with a NVIDIA Quadro K2200 graphics card. so you can change processor, add more hard drives, and even a secondary GPU.

Small Review About HP Z840 Workstation:

The sleek and sturdy hp z840 workstation review features uncompromised reliability, a tool-less chassis to facilitate upgrades, a lockable side panel to secure your valuable components and data, and handles to easily move the system around. The system’s elegant industrial design also boasts low acoustics, dual integrated Gb Ethernet, and aluminum panels. And this deskside powerhouse is also 5U rack mountable.

The HP Z840 is one of the coolest, most customizeable machines around. This is not a machine for your average user. For businesses and power users who need something with a ton of kick, you can’t go wrong. Just know that if you make the decision to buy this device, you will pay a lot, and you will get a lot in return.

Advantages of HP Z840 Workstation:

  • The Z840 supports dual Intel Xeon E5-2600v3 and E5-2600v4 series processors for the ultimate in power and performance.
  • The Hyper-Threading support allows two threads to run simultaneously on each core — Windows recognizes 88 total cores on this unit, 44 real and 44 virtual.
  • Turbo Boost which automatically boosts the processor speed
  • Using one of the 88 cores it will automatically increase the speed of the core in use and turn off the unused cores.

HP Workstation Z840 tech analysis or performance overview:

Using strictly Intel Xeon processors, the hp z840 datasheet hits processing speeds of up to 3.4GHz with the Xeon E5-2643 processor with six cores and 20MB cache or an incredible multi-core setup with the Xeon E5-2699 v3 processor clocked at 2.3GHz with 32 cores — 72 threads — and a 45MB cache and everything in between. With 19 different combinations of processors, the end user is able to meet their needs whether it be cost, performance or a mixture of both. These processing speeds and the ultimate amount of cores used in processing provide the finest in video rendering and exporting and can handle whatever you might demand of it.

In our test unit, the dual Xeon E5-2640 processors were tasked with everything we could throw at them. At one point we decided to be a little unfair and stream four 4K ultra high definition videos all while using our internet browser, Hyper-Pi benchmarking software, which calculates Pi to 32 million integers using multiple cores, and exporting a high definition movie from Adobe Premier Pro. Like we said, it was unfair. Though we saw the unit stutter and pause briefly, it flexed its muscles and took off again to complete our tasks.

Our only complaint with this review unit was a few times where the applications would hang while opening. Looking into it further, it might have been due to software issues rather than the unit itself. Running Windows 8.1 Pro we were able to run most applications, but needed to use compatibility mode for a few others. This may have been the issue we ran into and we are looking into it more to determine a final answer.

During our “fair” testing we used Adobe Premiere Pro to render and export full HD video, while simultaneously watching two 4K UHD videos as well as two 1080p videos. During this process there was not one bit of lag and the videos played smoothly. The video rendering and export completed amazingly fast and every other direction we gave to the HP Z840 was met with immediate results. This was not only due to the Xeon processors, but also to the incredible NVIDIA Quadro K5200 GPU. At 8GB of GDDR5 256-bit memory and using the Kepler architecture with 2,304 CUDA cores, and memory bandwidth of 192 GBps, the K5200 was a perfect addition to the Z840.

On 3DMark’s Cloud Gate 1.1, the Z840 had a physics score of an astounding 23,878 which was unreal, especially compared to a high-end gaming desktop which would score closer to 15,000. In Call of Duty 4, frame rates of 99 fps were obtainable at full resolution. Benchmarking tests used were Unigine Heaven 4.0, 3DMark 11 (Cloud Gate and Fire Strike), Call of Duty 4 using FRAPS for fps benchmarking, and Cinebench 11.5 for multimedia testing.

Unigine Heaven Benchmark 4.0: 3D Benchmark Test: 35.7fps, score = 899
3DMark 11 Cloud Gate 1.1: 3D Benchmark Test: 23,878
3DMark 11 Fire Strike: 3D Benchmark Test: 6,980
Call of Duty: Modern Warfare 3; Max quality, Native, AA/AF=4X/4X: 99 fps
Cinebench 11.5 Multimedia Tests: 16.43 MP Ratio; 2192 cb Multiple processor score and 133cb single processor score


It’s hard to find fault with the HP Z840. If you’re a Mac user, you may wonder why there isn’t an onboard Thunderbolt connector. HP does support Thunderbolt 2, though that support is limited to an optional add-in card. You might just want a different configuration of drive bays or expansion slots than is offered in thehp workstation z840. Some people still need legacy support for an old PCI card. Or you may have a 1394-based video device that you use almost daily.

That said, this is a substantial upgrade to the Z8 series workstation, primarily due to the recent advances in the Xeon processors and faster DDR4 memory. The new PCIe-based SSD option could be desirable if your work depends heavily on spooling large files from your hard drive. For companies that swap out projects or crews on workstations, the possibility of converting from 3.5-inch to 2.5-inch hard drives could be important. And if you work with large video projects that you prefer to keep entirely in memory while editing, the ability to stock your workstation with 64 GB DIMMs or even 128 GB DIMMs (when available) could make this an easy purchase.
