Dell Precision M6400 Covet review

Price when reviewed

No, the price at the top of this page isn’t a misprint. Dell’s high end mobile workstation – the Precision M6400 Covet – does, in fact, cost more than four grand; as much as a second hand hatchback, and considerably dearer than any laptop we’ve ever reviewed in the pages of PC Pro.

So why the high price? Just like the Lenovo W700ds, the M6400 is an ISV-certified workstation laptop. That means it’s been through rigorous testing to ensure that it will reliably run expensive CAD and design software such as Maya, Catia, SolidWorks and 3D Studio Max. When you’re spending hours rendering complex scenes or high definition videos with lots of effects, the last thing you want is for your computer to fall over halfway through.

Not that you’ll be waiting that long, because this is one seriously powerful machine. Under the hood you’ll find a 2.53GHz Intel Core 2 Extreme Quad Core QX9300 mobile processor, a whopping 8GB of DDR3 RAM, plus a rapid 7,200rpm 320GB Western Digital hard disk – a recipe that resulted in a mind-boggling score of 1.64 in our application-based benchmarks. It’s the fastest laptop we’ve ever tested, and significantly faster than the Lenovo W700ds, which scored 1.39 in the same tests.

So, to get a handle of that aspect of its performance we also downloaded and ran the SPECViewperf 10 benchmark suite. The results were stunning: in fact our rough and ready calculations put the M6400 ahead of the recent Workstation Specialists WS102LE desktop workstation by more than 50%.

That’s a hefty chunk of performance, but it can be faster if you want. The M6400 boasts twin hard disk bays, allowing you to increase performance using a RAID setup (incidentally, you don’t have to forsake the optical drive if you do). You can even specify two 256GB SSD drives if you’re feeling really flush.

More remarkable than this, though, is that the Covet is equipped with four DIMM slots where its rivals sport only two. That means adding large amounts of memory will be significantly cheaper, though you’ll still need to take out a small mortage to get right up to the 16GB maximum. Conversely, if the price above gives you palpitations, choosing the standard (non-“Covet”) M6400 allows you to downgrade several elements to save money.

But forget about the internals for a moment, cast your eye over the M6400 Covet’s fine figure, and you’ll fall in love with this machine. The chassis is wrapped in a tight-fitting aluminium jacket finished, in the case of the Covet, in eye-popping blood-orange.
