HP Z400 Workstation Review


Earlier this year we covered the launch of HP's latest Intel Nehalem-based workstations, and soon enough HP had a Z400 test unit for us to try out. The entry-point to the new range, the Z400 misses out on some of the more innovative design features of...

HP Six-core Z400 Test Drive, Part 1


Those users considering an HP workstation now have four units to choose from: the top-of-the-line dual-processor Z800 and Z600, which both sport the fancy new case that HP introduced last year, and the less-expensive Z400 and Z200...

These tests demonstrate what I stated at the top: that application performance on multiple-processor systems depends primarily on the multi-processor efficiency of the programs that you're using. If you're running Episode Engine in a relatively...

HP's Z400 Workstation Runs The Tom's Hardware Gauntlet


We've recently put a lot of effort into designing a custom benchmark suite for testing workstation-class hardware. It's a work in progress, first ...

Up until recently, the graphics card in a system largely dedicated to photo editing or video editing only needed to be powerful enough to drive the monitors, and 3D support was secondary to good quality 2D support. With the evolution of Nvidia's CUDA...

HP Z400 workstation


The Hewlett-Packard HP Z400 is the company's entry level workstation. While it doesn't have the whiz bang design features of the HP Z800 reviewed in March, it still does not disappoint as the benchmark numbers will surprise you.

On a pure price performance level, the system is hard to beat

HP's Z400 a workhorse workstation in any configuration

good but not 100% satisfied


I bought two of these systems and both had the above inventory issues. However I didn't bother doing an RMA since it would be a bit of a hassle. Instead I'll buy some more memory. Unfortunately Newegg can only do an RMA on the whole PC, and can't send...

Very clean system, looks almost new. Runs great. Was shipped with care and had great documentation. Top quality refurbishment job. Runs very quietly, and is a very well built system. I really like it ; I was surprised that it came with a USB keyboard...

Not quite as advertised. Only came with 6 GB of memory instead of 8 GB as noted in description. Also installed video card also differed from description (shipped with AMD Radeon). Not that big of a deal. A minor annoyance is that there were no extra...

What I expected, except....


If you're going to order a refurb, do yourself a favor and order all the RAM you'll want with it. These pro systems can take only particular RAM types and they sometimes cannot be mixed and matched. Plus, new RAM is always more expensive than the RAM...

It's exactly what I expected. I dumped Windows and threw Linux on there. It runs very well. It's also very quiet. . Which is fine for what I need. The case was in very good condition and the inside was clean and in good order. In the future I might...

It came with Nvidia Quadro board with the VESA 59 connector. I wound up ordering a dongle through another retailer because I couldn't find it on NewEgg. It would have been nice to know ahead of time or to include the dongle. (I would rather have had...

Great Value


Great value, good cpu for CAD operations and other workstation applications. For the money, you won't find a better system

Slower hard drive, no USB 3, but that's expected on an older chipset
