For those who can afford the upgrades, HP offers tremendous choices any enthusiast could ever ask for. Aside from the latest Intel Xeon processors that supports wide range of chips, such as Intel Xeon E5-2603 v3 to Intel Xeon E5-2699 v3 processor, it can also be configured to support two Xeon E5-2699 v3 18 core 2.30 GHz processor. To put things in price perspective, two Xeon E5-2699 would mean additional $6,990 USD. It is expensive yes, but then again, this is not your ordinary computer. It is for professional specialized use.

RAM is also customizable, and can go anywhere from 4GB DDR4-2133 RAM to the max that the HP Z840 can hold which is 512GB DDR4-2133 RAM.

The PC supports DDR4 memory and runs with 4GB Nvidia Quadro K4200 graphics card, resulting to stellar benchmark test results. The system topped the CineBench score at 2,588 points, which is the highest score we have seen, and easily outpaced other workstations with single processor system such as HP Z1G2 (724 points), Lenovo ThinkStation P300 SFF (747 points) and Falcon Mach V (GTX 980) (1717 points). Basically, should you need multithreaded and powerful computer for processor-intensive work, then the HP Z840 is the right one for you.

Running this kind of power in Photoshop CS6 for removing blemishes will be overkill. For 3D gaming, this computer has no problem playing games on their extreme frame rate settings. Though the NVIDIA Quadro K4200 graphics card is made for precision graphics than absolute animation speed. This amazing combination of high-end processor performance, expandability, upgradability, and newer technologies like Thunderbolt 2 and DDR4 memory easily makes HP Z840 the peak of high-end performance, perfect for people who need it.

For engineering and IT support, this rig definitely has all the bells and whistles you will ever need. In terms of features and performance, it easily outpaces previous dual-processor workstation like Lenovo ThinkStation D30 and Lenovo ThinkStation C 20.

For its boot drive, there’s one 256GB SSD, while the others work as data drive. This means you can choose which data drive set as your local storage and which will be your scratch drive for the workstation apps you use on a daily basis. Both of its graphics card and processor are ISV-certified for wide array of apps. You can check out HP’s website for their updated list.

As expected, the only program you can find in its boot drive is the standard HP workstation and the standard Microsoft utilities.



Design and Features

Simple, Yet Elegant and Professional Design to Fit to Anyone’s Work Desk

In the past couple of years, designs of business-class workstations have improved significantly, as more and more companies now realize the benefits of sleek-looking PC towers to complement anyone’s workstation. HP indeed, took notes, as they make modern, simple, yet sleek-looking tower in HP Z840.

The rest of the bezel is incognito black frame, which gives a simple, yet elegant look. Aside from that, the chassis comes with two handles for carrying, and rightfully so, as this machine can be heavy, depending on your customization.

The front panel houses the memory card reader, along with the slot with DVD RW. On its offset side are the Power and Reset button, as well as the four USB 3.0 ports, and auxiliary in and out ports.

Most high-end desktop towers are personalized. People get them on case-by-case basis and choose hardware and specs that suits their work best. Basically, these PCs are overkill for standard general computer work, clerical and sales workers. The base configuration comes with a single Xeon processor and a regular hard drive, no graphics card included.

The interior of the chassis is equally impressive. The tower has a massive mountable rack with plenty of room inside for upgrades. There’s also enough space to add four more 3.5-inch hard drives through the removable sleds, and two open optical drive bays. There are also lots of free SATA and SAS (Serial Attached SCSI) ports to support these drives. Also, there’s an extra PCIe x16 card slot to accommodate the second graphics card, then one PCIe x8 (x16 physical) slot, as well as PCIe x1 slot to support cards with lower-bandwidth, like wireless networking cards.



Massive Power Supply to Support High-End Specs and More Upgrades

This desktop comes with a big 1125W power supply, which means it is ready for high-end graphics card upgrades and accommodate more hard drives. The way HP Z840 arranged its interior makes it easy for users to put in and replace anything. The air-cooling duct covers are perfect for the job; they are easy to remove (with green handle markings) and everything aside from the motherboard and CPU are tool-less.


Generous Set of Connectivity Options

This desktop PC also comes with generous set of inputs/output ports. There’s one DVI port, 2 DisplayPorts on its Quadro card and ports for audio line-in and line-out. Then there are two Ethernet ports, two PS/2 ports for the good old keyboard and mouse, two USB 2.0 ports, and 8 USB 3.0 ports (four in front side and another four at the back). The Thunderbolt 2 card comes with a Thunderbolt 2 port and DisplayPort input, which means daisy-chaining your Thunderbolt display to Thunderbolt devices and drives is made simple. There’s also a DVD burner with archived data retrieval and program installation. As you can see, the only thing missing is the HDMI port, but of course, you can always connect your HDMI to Quadro card using a DisplayPort adapter.
