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

The Z400 And Benchmarking Notes

All in all, the Z400 sports a fairly standard X58-based motherboard. The one exception is the memory slot configuration on our first-gen board, which HP has since rectified with a six-slot follow-up, allowing two modules per channel.

While it may seem that this is greatly reduced from your average enthusiast board, remember that these platforms have a different purpose and market segment than those boards. These systems stress reliability and availability as much as performance. There won’t be any detailed conversations about overclocking settings available in the BIOS, because there are no such provisions.

Most workstation motherboards only have a single PCIe x16 slot for graphics. It was only recently that workstation software supported SLI and CrossFire, and thus the systems weren’t equipped for it either. Most server-oriented motherboards have onboard video and lack an x16 slot at all. Instead, they include multiple x8 slots for storage and networking controllers.

The Intel Xeon W3520 processor the machine is equipped with is very similar to Intel's now-EoLed Core i7-920, which shares the same clock speed and most of the same features. There are only two differences to be seen between the two: the Xeon W3520 supports ECC memory and Intel Demand-Based Switching, whereas the Core i7-920 does not. With that said, DBS in the workstation space is what SpeedStep is on the desktop.

Testing Workstations

Testing workstations for Tom’s Hardware is quite a bit different from evaluating the latest desktop CPUs and graphics cards. In approaching the methodology, the benchmarks need to persist for longer than the typical mainstream app, and they need to be intensive enough to demonstrate the performance differences between very similar machines, meaning tests that only take a few seconds to complete are out of the question. Also, the tests must be repeatable and objective. That is, the differences between systems must be measurable in a quantifiable way. “It feels faster” doesn’t cut it.

Over the past several years, SPEC (the Standard Performance Evaluation Corporation) has attempted to create tests that can be used to benchmark systems against each other, including the SPECapc (SPEC application performance characterization) tests. The SPECapc tests are scripted workloads that measure the performance of actual applications. Unfortunately, the SPECapc tests usually only work correctly under the version of the software that they were designed under, and if the test isn’t updated for newer versions of the software, then people trying to evaluate workstations are left trying to size them up using older software. This can lead to disparities between old and new code that go on for five years or more. Also, the SPECapc benchmarks may be enough to weigh down the machine for substantive testing purposes, but those tests, in many cases, do not accurately represent a ‘production workload.’

So, we here at Tom’s Hardware have developed a few workstation tests of our own that we feel are a better approximation of real workloads. In many cases, they should be familiar to people performing production-type tasks. With experience in the digital content creation industry and regular contacts working in the industry, we were able to get a feel for active professionals would like to see in benchmark tests.

Hewlett-Packard supplied the Z400 workstation on extended loan, both as a review unit and as a test case for the development of our new workstation tests. These workloads were developed on the Z400 with the express intent of bringing it to its knees, and we managed to do that after months of work. The suite, as it stands, is not written in stone. And it is our aim to expand them and possibly change some tests to increase their demand--hopefully with some suggestions from you. We tried to cover multiple market segments, but the initial tests are heavy on the DCC (Digital Content Creation) market segment and light on others. This is something we hope to remedy.

    So JF was right to say that HT should be disabled in some scenarios
  • haplo602
    hmm ... I wonder if you could make a D3D/OGL comparison test in some 3D modeling software ? I don't actualy know if any of them supports both APIs.

    BTW you dual PCIex16 comment is wrong. There were dual PCIex16 slots in HP workstations since xwX400 models (6400,8400,9400).
  • Draven35
    Some of the other models have dual x16 slots... but they are rare in baseline models. At some point we'll look at how well an SLI config works in workstation OpenGL tests.

    3dsMax uses Direct3D (and OpenGL), but prefers Direct3D (it is 'recommended' by Autodesk on my GTX 460-equipped primary machine...), but Maya does not, it requires OpenGL.

    As for whether HT should be disabled? Still questionable. If you're doing animation, and have HT off, you'll gain some interactivity when working, but as soon as you need a test render you'll be losing time. If your 3D application does multithreaded interactiivty tasks, then you're better off with HT on- for instance, the VPR interactive shading mode in Lightwave 10. Its largely dependent on how your software responds to what, and hopefully we'll have more answers on that with the next workstation we look at.

    Nice cable managment...
  • Draven35
    It came that way! The other models in the z-series have better cable management even, specially with the shrouds.

    Lets see.

    2GB Ram - Not even close to be considered a usable workstation. - Nevermind, I messed up. I didn't see the (x3)

    250GB main/2TB raid 0 - raid 0 setups in workstations are used for scratch disks, and thats it - storage is too risky. 2x 250GB in raid 0 makes much more sense cost wise as you'll never use more than 500GB on a scratch disk, with a 1TB for temporary storage. I say temporary because a workstation is just that, once the work is done (and during) it's backed up and rarely used again.

    Creative Labs X-Fi Titanium PCIe - Any Audio professional needing sound quality is going to be using almost exclusively external hardware. The analog outputs all anyone else is going to need.

    Who ever chose the specs for this machine needs to be shot.
  • MU_Engineer
    This was an interesting review, but the real machine to test would have been the dual-processor Z800. The big advantages of a workstation are better reliability and stability than a standard desktop and the ability to use multiple processors and more RAM than a typical desktop. Perhaps a Z400 vs. Z800 test would have been interesting as there were a mix of poorly-threaded and well-threaded applications in the test.
  • warezme
    This machine is pathetic. Any decently configured OC'ed quadcore i7 will run circles around this thing, ugh.
  • Draven35
    It was agreed to start with a z400... the workstation tests were actually developed on this machine, hence why it has a Gen 1 board. Mayhap we'll look at a z800 later.

    Most video editors use a RAID array for their video files unless they are just editing DV. HD footage shot on a decent quality camera would quickly overwhelm your proposed 500GB array- the raw P2 footage alone for my film project was 350 GB, and that's before the scratch files generated for color correction and transition renders- and the P2 footage is pretty strongly compressed for semi-pro camera footage. (40 Mb/s) If you're editing uncompressed 1080 HD, you're dealing with 124 MB per second of video. With a larger array, a system like this could be set up for editing uncompressed HD with the simple addition of a BlackMagic Decklink in one of its HD flavors, or the HD version of the Avid Mojo if you prefer to work in something like Media Composer. With the transition of TV to HD, more and more projects are being finished for HD in an attempt to future-proof them- which has actually been going on for about five years before the transition. If you want to see something truly horrible, look at the data rates required for 2k or 4k playback...

    HP doesn't sell their machine configured with any kind of professional audio interfaces. They submit their machines for certification by Avid, and the 'full' Pro Tools (Pro Tools HD) comes from Avid on a z800.The audio interface choice for the system was either the Creative card, or the onboard RealTek codec, because that's what HP had and could configure a system with.

    You'll find a surprising number (like, most) audio guys including musicians these days working with a mix of software and hardware, and the mixing is done on a computer, not on external hardware. There are audio interfaces with two, four, six, eight and more inputs... my personal music workstation has eight analog inputs, plus ADAT and S/PDIF in. (Note, I need more like twice that in inputs.) You need all these input to capture multiple instruments on completely independent tracks simultaneously , so that they can be given separate effects and the mix can be adjusted on each track. (That's right, you can capture all those tracks at the same time.) Some of these audio interfaces are an internal card , some are an internal card plus an external breakout box (M-Audio Delta series, MOTU 2408, etc), and most are USB or firewire external (Presonus, TASCAM, Echo, Digidesign, Focusrite, et al) boxes with all the hardware located within it. In addition, many have PCI or PCIe DSP accelerator cards from UAD or TC electronic for effects processing and synthesis.

    The big advantages of a workstation are better reliability and stability than a standard desktop

    I'm not sure I understand this. A machine built with the best enthusiast-class hardware should be basically 100% reliable. The most unreliable part is the hard drive. This machine uses Seagate hard drives, probably the most unreliable brand of drives. This machine also uses an HP motherboard, and HP is below average in reliability in their retail products. Should we expect the workstation components to be better? As for stability, it's using the same OS that everybody else has access to.

    All of our CAD machines here use i5/750 CPU's, aftermarket coolers, 8GB, Gigabyte motherboards, a Velociraptor or SSD for the boot drive, a WD Black for the storage drive, ATI FireGL video cards, Win7 Pro 64bit. The machines run at 3.5GHz 24/7 with no problems. I add 2 cooling fans to each case and that in conjunction with the aftermarket cooler keeps things running real cool.
