Dell M6500: Specced to the Hilt

The M6500 marries high performance components with an understated aesthetic. It's definitely not going to challenge any thin and light notebooks for the pure mobility crown, but it's great to get a notebook that doesn't try to proclaim it's awesomeness with a bunch of superficial bling. We're also ecstatic that we don't have to worry about fingerprints marring the exterior for a change. Let's start with a quick rundown of the configuration options.

The specifications of the Precision M6500 are a Who's Who list of high-end components. Take the best mobile parts (at least as far as raw performance is concerned) and they're nearly all available as a configuration option. You can configure up to a Core i7-920XM, three SSDs/HDDs, a Quadro FX 3800M graphics, and up to a whopping 16GB (4x4GB) of DDR3-1333. The memory department in particular deserves special mention, as the M6500 has four SO-DIMM slots compared to the typical two (sometimes three) we see in most other notebooks. Right now Dell "only" supports 4GB SO-DIMMs, which isn't a huge problem considering 8GB SO-DIMMs are very difficult to come by (and expensive); still, given the target market we're a little surprised Dell hasn't validated any 8GB SO-DIMMs.

The unit we received for review is now slightly "outdated", as Dell is now shipping M6500 systems with Core i5 CPUs and optional USB 3.0 support. Note that at present, USB 3.0 is only available if you select a quad-core i7 configuration. Dell also ships the M6500 in an "Energy Star" compliant package, which consists of a slim 210W/240W power brick (presumably higher efficiency, though Dell doesn't make this clear) and requires an NVIDIA Quadro GPU. Our test unit came in the Energy Star configuration, though without both power bricks we can't confirm whether the "Energy Star" power profiles actually make a significant difference.

The only area where maximum performance isn't an option in Dell's configurator is the storage department. Dell has SSDs and encrypted SSDs available, but what you won't find are the top performing Intel SSDs—or Indilinx, SandForce, or C300. Considering the enterprise market, that's not especially surprising (Anand has managed to brick both an early SandForce as well as a C300); Dell goes the safe route like most OEMs and uses Samsung SSDs. Like many other SSDs, Samsung suffered from degraded performance once a drive was in a "used" state, but with the latest firmware and TRIM support that's no longer as much of a concern. For most usage scenarios, the Samsung SSDs perform well and are available in sizes up to 256GB. The only flaw in Samsung SSDs is random write performance; while they're an order of magnitude faster than conventional HDDs, the best SSDs are another order of magnitude jump. However, in normal usage (measured by PCMark Vantage), the best SSDs are only about 10% faster than the Samsung, which is around twice as fast as a 10000RPM Raptor. On the other hand, supporting three drives (if you're willing to give up the internal optical drive) is a nice bonus

The other item that we really need to applaud is Dell's RGBLED backlit WUXGA LCD with an anti-glare coating. This is a great looking laptop LCD—almost the best we've tested to date. It's bright, it has a great color gamut, and the contrast ratio is good as well. It also has the best viewing angles we've seen from any TN panel, though we can still wish for an IPS panel—a rarity at best for laptops. The base model has a 1440x900 glossy WXGA+ panel with CCFL backlighting; $160 will bump you up to glossy 1920x1200 WUXGA with CCFL backlighting, while $300 gets the tested anti-glare 1920x1200 RGBLED panel. We figure if you're going to spend a lot of time with a notebook like this, and you're already spending a few grand, the $300 extra is money well spent. The only caveat is that the LCD has a definite blue tinge using the sRGB and AdobeRGB profiles, which results in calibrated Delta E results that are much worse than other laptops. You'll want to run the NTSC profile in the Dell ControlPoint utility to use the LCD in "native" mode; read the LCD results page for additional details.

Most of the remaining specs are typical, with various WiFi, Bluetooth, and mobile broadband options. The keyboard is quite good in nearly all respects, and it's backlit as an added bonus. The one thing we missed on the keyboard was a dedicated context menu button (normally located to the right of the spacebar). Perhaps I'm one of the few people that use such keys, but I definitely noticed it was missing. The number keypad on the other hand is great, with a layout that mimics what that of desktop keyboards. Unfortunately, there's only a DisplayPort and VGA port for external video, and there are also just four USB ports—one more than consumer laptops, but there's a ton of open space on the sides of the chassis that could have been used. At least Dell provides a powered FireWire port and ExpressCard/34 slot, and they even provide a PC Card slot for customers that need support for older devices. There are also several security options available: TPM 1.2, FIPS Fingerprint reader, Smart Card reader, contactless Smart Card, and Wave Embassy Trust Suite. And if you're not sure what half of those items are, the M6500 might be overkill. :-)

Dell provides a 3-year warranty standard on the M6500, with optional 4- and 5-year warranties for an additional charge. 3/4-year accidental damage and 2/3-year battery warranties are also available. Considering the cost of the M6500, we're glad Dell doesn't skimp out on the warranty. In fact, standard 3-year warranties are common on most business laptops (along with anti-glare LCDs), so keep that in mind if you're every looking for replacement with those features.

    Dam I just bought one of these and the screen shuts off whenever it wants. I bought on ebay as a new computer with a 3 month warranty. This computer had this problem from day one. I have been reading on the Solidworks forum than many others also have this problem. So far there is no solution. With one guy, Dell replaced everything in the laptop with no luck and eventually they replaced it with a M6600 machine. I think I am sunk because the fellow I bought it off seems reluctant to give my 2K back.

    crt monitors are still superior and yes, projectors also often have dsub15 connector - that's why.
    it has digital display connector anyway...
