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...

In terms of cost, the range starts from $929 for preconfigured models, which nets you the 2.4GHz Xeon dual-core; quad-core models start from $1,499, and a rig comparable to our test unit – with the 2.93GHz CPU – will be more in the region of $2,500....

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


The Lab tests a powerful workstation-level desktop computer from HP, the Z400.

Many expansion slots and Serial ATA ports

Support bar interferes with some accessibility

Consumer review by:

Not bad!


Great for businesses that don't require cutting edge workstations and are on a light budget. I bought these for a car dealership.

Price is great, server class quad core processor, Intel Turbo Boost, dedicated business class graphics card

Graphics card is relatively weak (although still better than onboard)

Consumer review by:

Great price for base system


I will order another one of these because I saved over $400.00 dollars. It came within 3 days using free shipping, it was packed correctly, instead of buying piece by piece if you can find a setup this will save you big money. I'm already looking again...

Decided to try another refurbish product glad I did. Cost effective, was able to get exactly what I needed to build up more for half the price. I added two more hard drives and used this for a media server for my media center. Glad I did, saved me big...

zero, received exactly what I ordered, no noticeable differences from brand new

Perfect for the money


Super fast for the money and age of the machine

Other than some cosmetic damage nothing so far

Consumer review by:

Great pick up at $350.


Exactly what I expected for the price. No unneeded preloaded garbage. plenty of room for upgrades. Good ventilation on case

As previously stated the stock 450 watt power supply won't cut it for a gaming rig and the 600 watt upgrade is discontinued and somewhat hard to find by my research (because it is proprietary). I guess with a little know how you could try and rig...
