The Highest-End Notebooks, 2009

A couple weeks ago we looked at Intel's new Clarksfield mobile CPU. The short story is that it's the mobile equivalent of Lynnfield, except at lower clock speeds and higher prices. We provided a first look at Clevo's W870CU and compared it with a couple other high-end offerings: the AVADirect Clevo D900F and the Eurocom M980NU XCaliber. We didn't have time in our initial article to run all of our usual benchmarks, so today we want to look at the rest of the story and finish out our benchmark suite. We will also be providing detailed commentary on the design and features of the three notebooks -- something we omitted in the first article.

Taken as a whole, these three notebooks represent the high water mark for mobile performance for the next several months -- and perhaps longer. The AVADirect D900F is the pinnacle of "mobile" processor performance… not by using the fastest mobile processor, but by using the fastest currently available desktop processor. Clocked at 3.33 GHz, the Core i7-975 outperforms any Core i7 mobile CPU by a sizable margin. With one core active, Turbo Boost on the i7-920XM can reach 3.2 GHz, but that's as close as you can get (and the i7-975 can still Turbo up to 3.60GHz). Considering the two processors have the same price tag of $1000, the only reason to go with an i7-920XM is if you want lower power requirements.

On the other side of the table, the Eurocom M980NU represents the best of what we can achieve in mobile graphics performance. It pairs two of NVIDIA's GTX 280M GPUs in SLI. Needless to say, the two graphics chips can consume quite a bit of power, so the trade-off is that SLI is only practical right now when using mobile CPUs, and at present GTX 280M SLI is only available with Core 2 platforms. A similar notebook in terms of performance is Alienware's M17x, although the chassis and design is substantially different from the M980NU. Thus, you can choose between maximum processor performance (D900F) or maximum graphics performance (M980NU/M17x), but you can't get both.

The odd man out is the Clevo W870CU. In terms of graphics performance, it can match the D900F, but it's never actually faster. It can exceed the M980NU in CPU performance at times, but it can't keep up with the SLI gaming performance (unless the M980NU is CPU limited). What it does have is the ability to consume less power, sometimes quite a bit less. Unfortunately, this is counteracted by battery sizes. Where the D900F ships with a 12-cell battery, the W870CU only comes with a 4-cell battery. The model we received is rated at a paltry 42 Wh, although it appears that a high-capacity 65 Wh battery is an option at some vendors. Interestingly, the Eurocom M980NU also lists a 4-cell battery, so potentially we could see an 8-cell version offer nearly twice the battery life. Considering the size of the battery compartment, what we'd really like to see is something closer to the 95 Wh battery available in the D900F. The only reason to avoid such a large battery appears to be weight, and the W870CU is 3 pounds lighter than either of the other notebooks if that matters to you -- but it still weighs almost 9 pounds.

Besides performance, there are obviously differences in terms of chassis, features, and pricing. The W870CU is the cheapest of the three notebooks, starting at around $2150 and coming with moderately high-end options for around $2900. The D900F and M980NU both start at closer to $2500, with typical configurations ranging from $3000 up to $3500. If you want to start putting in multiple SSDs, you can of course get prices that scale into the $5000+ range.

As usual, if you're not in the market for a heavy, high-performance notebook it's unlikely you will be interested in any of these offerings. Battery life is horrible, typically lasting around one hour for moderate usage scenarios. As such, the mobility aspect should be viewed more as a UPS/battery backup instead of something that you will be able to use to go mobile. (Note that we'll look at the Alienware M17x separately in the near future, as it has slightly different mobility aspects.) These notebooks do have the ability to function as desktop replacements for many people, but again performance is going to be lower than what you can get in a similar cost desktop. The benefit is that you can easily pack up a notebook and carry it with you, and there are people that do exactly that, using these as mobile workstations. Now let's take a closer look at these three notebooks and see where they excel and where they may fall flat.
