The Lenovo ThinkStation P900 Workstation Review: Design 101

Video Conversion – Handbrake v0.9.9: link
Handbrake is a media conversion tool that was initially designed to help DVD ISOs and Video CDs into more common video formats. The principle today is still the same, primarily as an output for H.264 + AAC/MP3 audio within an MKV container. In our test we use the same videos as in the Xilisoft test, and results are given in frames per second.
The single thread frequency on a high core-count processor is usually lower than a similar TDP low-core count one, and as a result the low quality conversion performance is down on a good Haswell quad core. On the other hand, moving to double UHD sized frames allows the P900 to stretch its legs. Performance isn't exactly 3x the 5820K here based on core count, but it does take an extra chunk of performance.
Point Calculations – 3D Movement Algorithm Test: link
3DPM is a self-penned benchmark, taking basic 3D movement algorithms used in Brownian Motion simulations and testing them for speed. High floating point performance, MHz and IPC wins in the single thread version, whereas the multithread version has to handle the threads and loves more cores.
Similar results to HandBrake here, but the multi-threaded version of the benchmark is memory independent, allowing the 20 cores / 40 threads to stretch its legs.
Compression – WinRAR 5.0.1: link
Our WinRAR test from 2013 is updated to the latest version of WinRAR at the start of 2014. We compress a set of 2867 files across 320 folders totaling 1.52 GB in size – 95% of these files are small typical website files, and the rest (90% of the size) are small 30 second 720p videos.
Despite the semi-threaded nature of WinRAR, having 40 threads helps in compression here.
Image Manipulation – FastStone Image Viewer 4.9: link
Similarly to WinRAR, the FastStone test us updated for 2014 to the latest version. FastStone is the program I use to perform quick or bulk actions on images, such as resizing, adjusting for color and cropping. In our test we take a series of 170 images in various sizes and formats and convert them all into 640x480 .gif files, maintaining the aspect ratio. FastStone does not use multithreading for this test, and thus single threaded performance is often the winner.
FastStone relies on single thread performance, so we see it further down the charts.
Rendering – PovRay 3.7: link
The Persistence of Vision RayTracer, or PovRay, is a freeware package for as the name suggests, ray tracing. It is a pure renderer, rather than modeling software, but the latest beta version contains a handy benchmark for stressing all processing threads on a platform. We have been using this test in motherboard reviews to test memory stability at various CPU speeds to good effect – if it passes the test, the IMC in the CPU is stable for a given CPU speed. As a CPU test, it runs for approximately 2-3 minutes on high end platforms.
POV-Ray is also heavily multithreaded, allowing any big cores to push through.

Actually in my experience we do the vast majority of the servicing ourselves, especially for desktops. Literally all I have to do is live chat with Dell's support for IT Departments, tell them that a computer we recently received had the power connector going into the DVD drive break off inside the DVD drive some how, and they next day ship me a replacement PSU and my user has a working DVD drive within 24hrs. And THAT'S what good manufacturer support is, a trusting relationship between manufacturer and IT Department goes a long ways. Sending out equipment for repairs is slow and a pain. And having someone come on-site is a waste of money for the manufacturer and time for us because we need to make sure we are available when they get there instead of repairing it on our own schedule. If you're a "real IT department" for a few hundred computers, you really can't afford the time to have someone else do the repair work.And you'd also be surprised how many things that SHOULD have been EoL'd don't get EoL'd! Just because it isn't under warranty doesn't mean we want to just throw it out especially when you have 100 of the same thing (aka spare parts which means immediate repairs). And some departments are happy with what they have and don't want to go by the set EoL schedule for their computers and use their funds elsewhere. They pay for it with extra downtime when something does break, but they know that it's their own fault.

My HP servers, workstations and printers order parts that fail\deplete automatically. When I show up to work the next morning at 8AM, the support technician that arrived at 6AM is walking out the door and everything is fixed.That's real support. And it's included with every HP Elitedesk/Elitebook, Laserjet Pro\Officejet Pro, and Proliant server I've ever managed for 3 years unless you purchase a "smartbuy" with a 1y/1y. The craziest thing about HP warranties is the ADP (accidental damage protection) is only 6%/year the cost of the machine. So a $1000 Elitebook is <$200 to cover for 3 years against user destruction. The equivalent Applecare on a $1000 Macbook is $269, and Lenovo charges $229 with no option for next-day.

Small business solutions without internal it department often likes easy to service, replace and upgradeable hardware. Not only because those solutions might offer good value for their money in small business solutions, but as well because external IT consulting likes to make a buck with their own support.Besides that you are absolutely right. If there is a real IT department than usually they prefer to buy support, reliability and just cycle out stuff that stop working - with a few exceptions when old hardware is needed for special use-cases or getting some time for bigger rollouts.

I don't think that the system is particularly hard to service. To remove the power supply (and only the power supply), you remove the side panel, open a door, and slide the power supply out. I assume that the Dell has something that keeps the power supply from accidentally falling out of the case when the side panel is removed, so I would think that remove the power supply from the Dell takes the same number of steps, or more.To access the DIMM's you remove the side panel and the central baffle. Removing the baffle is an extra step, but before we can say definitively that the Dell wins on this measure we would have to compare the time to remove the side panel on both systems.
As for fans that slide in and out, I'll grant you that fans don't fail very often, but if one ever does fail the Lenova allows you to slide out the failed fan and slide in a replacement after removing nothing other than the side panel.
I agree with you about price. I couldn't find a comparable computer on the Dell web site, but AVA Direct will sell a comparable computer for a tad over $10,000. The P900 is only worth considering if you need a large numbers of workstations and can get Lenovo to agree to a large quantity discount.
Freakie - Thursday, May 7, 2015 - link
That's the problem though, being built for too many "what if's". And I hate break-out boards in units too, they are notorious for dying and don't really serve a purpose that a different internal design can't solve. The design of the P900 is just so superfluous. Just having the insides look pretty is a waste because no one is looking at the insides, and of course there is no side window. It just screams unnecessary.The Dell Precision 7910 is the one I was referencing in my original comment. I specced it out online and it came out to ~$5,000 less than this and I doubt that you are going to get a $5,000 discount per-unit on these Lenovos. And if you're ordering that large of a volume, might as well ask your Dell rep for a volume discount as well.

Yep, I did the same and it came out to around 10,500-$11,000. Based off of this review I too prefer the internal layout of the latest Precisions, they're simple and well thought out. Definitely an improvement over the prior design at least.edlee - Wednesday, May 6, 2015 - link
I have had great experience with Lenovo professional products, thinkserver tower and rack servers similar well thought design and high end power supply. Please try to review an 8 bay thinkserver as well so we can compare to commercial 8 bay naszachrohlfs - Wednesday, May 6, 2015 - link
Would really appreciate some benchmark scores from programs like Solidworks, Revit, Adobe Suites and graphic design programs.While the review is nice it makes it hard to sell anything to a company with out some comparable data on the programs you use.

PS. Ian, pleeeease stop using the Blinkenlights site for the C-ray link! :D I don't control that site, it's just a mirror. The main C-ray link should be here:http://www.sgidepot.co.uk/c-ray.html
Sometimes I can't even connect to Blinkenlights.

The advertising on the sides of the page is extremely off-putting. The ad is so close to the article text that it is making the article difficult to read. I have been coming to this site religiously since before the days of the celeron (the abit BP6 brings back many fond memories) and almost all my computer related purchases are based in part on reviews here. But this latest style is a bridge too far. Please fix it, or I'll be forced to look elsewhere.....
