Toshiba Satellite L645D: Mobile AMD at 3GHz
While the drought of Sandy Bridge notebook hardware is thankfully approaching its sweet, merciful end, there are still a healthy amount of AMD-based notebooks on the market at good prices awaiting happy homes. Toshiba was kind enough to send us their L645D, a 14" notebook sporting a mobile Phenom II dual-core processor running at a speedy 3GHz, Radeon HD 4250 integrated graphics, and a Blu-ray drive: all yours for a potentially exciting value proposition of just $619. Is it worth it?

Supporting the N660 is 4GB of DDR3-1066 and the aging Mobility Radeon HD 4250. As I've harped before, the 40-shader 780G was a fine IGP when it landed, but time has been unkind to this particular core design, and the minimal update to DirectX 10.1 just hasn't been enough. The 4250's 40 shaders run at 500MHz, down from the 700MHz the 4250 runs at on the desktop. It's still more desirable than Arrandale's Intel HD graphics due to generally superior driver quality and compatibility along with similar overall performance, but as you'll see, Sandy Bridge's Intel HD 3000 graphics mop the floor with it. Thankfully the 4250 is not long for this world; AMD's ultraportable platform now favors the E-350 with its far more capable Radeon HD 6310 IGP, and Llano is drawing ever closer.
Rounding out the L645D is the bare minimum of connectivity and an anemic 640GB 5400RPM hard disk. Toshiba's mobile hard disks have typically been poor performers, but I imagine it keeps costs down and at least the capacity is generous. The highlight, however, is the inclusion of a combination Blu-ray reader/DVD writer. With an asking price of $699 MSRP and online price of $619, this notebook comes within striking distance of the recently reviewed Sony EE34.

Gaming Laptop Roundup
Standard Gaming Performance
Starting the benchmarks, we'll cut right to the chase and begin with gaming performance. That's what you buy one of these laptops for, after all. As mentioned in our last article, we have recently updated our laptop gaming benchmarks. We use built-in performance tests on Company of Heroes, Crysis, Devil May Cry 4, Enemy Territory: Quake Wars, and Unreal Tournament 3. For Assassin's Creed, GRID, Mass Effect, and Oblivion we benchmark a specific scene using FRAPS. In all tests, we run each benchmark at least four times, discard the top result, and report the highest remaining score. We will use resolution scaling graphs to compare the different laptop configurations, as that will allow us to examine how the GPU and CPU affect performance. At lower resolutions we should become more CPU limited, while the higher resolutions and detail settings should put more of a bottleneck on the GPU.
The Gateway notebooks obviously offer a lot of bang for the buck, even if they don't top the performance charts. The Alienware m15x is faster overall, but the margin of victory over the P-7811 is only about 7% (around 25% over the P-171XL). As we mentioned in our Gateway P-7811 review, there also appears to be a driver glitch with the P-171XL in Devil May Cry 4 - which incidentally is the only game where we don't see significant performance improvements from SLI at higher resolutions. The Sager NP9262 is clearly in a league of its own when it comes to performance. If you've ever wondered why people would consider purchasing a heavy SLI notebook, gaming performance that's almost twice as fast as the closest single GPU solution is the answer. Unfortunately, that means the CPU becomes more of a bottleneck, which is why we see several games where the Sager laptop has an almost flat line.

Laptop LCD Roundup: Road Warriors Deserve Better
Two of the areas where we've seen the most growth in the last few years are notebooks and flat-panel displays. The reasons for the tremendous growth differ, of course. Notebooks are a hot item because people are becoming enamored with wireless networks and portability, while LCDs have become popular because few manufacturers are making CRTs anymore and the small footprint of LCDs is desired by many people. We're working on increasing our coverage of both of these sectors, but up until now we haven't actually taken a close look at where they intersect.
Since the first laptops began shipping, LCDs have been the de facto display standard. Years before most people were using LCDs on their desktop, laptops were sporting these thin, sleek, attractive displays. As anyone who used one of the earlier laptops can tell you, however, the actual quality of the LCD panels was often severely lacking. With the ramp up in production of both LCD panels and notebook computers, you might be tempted to assume that the quality of laptop displays has improved dramatically over the years. That may be true to a certain degree, but with power considerations being a primary factor in the design of most notebooks, compromises continue to be made.
Without even running any objective tests, most people could pretty easily tell you that the latest and greatest desktop LCDs are far superior to any of the laptop LCDs currently available. While desktop LCDs have moved beyond TN panels to such technologies as S-IPS, S-PVA, and S-MVA we are aware of only a few laptop brands that use something other than a TN panel. (Unfortunately, we have not yet been able to get any of those laptops for review.) We have also complained about desktop LCDs that have reached the point where they are actually becoming too bright, in an apparent attempt to win the marketing war for maximum brightness. The same can't be said of laptops, as very few can even break the 200 cd/m2 mark. Individual preferences definitely play a role, but outside of photography and print work most people prefer a brightness setting of somewhere between 200 and 300 cd/m2.
Luckily, there are plenty of new technologies being worked on that aim to improve the current situation. Not only should we get brighter laptop panels in the near future, but color accuracy may improve and power requirements may actually be reduced relative to current models. LED backlighting is one technology that holds a lot of promise, and it has only just begun to show up on desktop LCDs. Dynamic backlighting - were the brightness of some LEDs can be increased or decreased in zones depending on what content is currently being shown - is another technology that we may see sooner rather than later. Then there are completely new display technologies like OLED.
With the current laptop landscape in mind, we have decided that it's time for us to put a bigger focus on the quality of laptop LCDs. To accomplish this we have put together a roundup of the current notebooks that we have in-house. Future laptop reviews will continue this trend by including a section covering display analysis and quality, but we wanted to build a repertoire of past notebook displays in the meantime. While we only have four laptops at present, it is also important to remember that there are only a few companies that actually manufacture LCD panels. We would also expect any companies that release notebooks with higher-quality LCDs to make a bullet point out of the fact, which means that if you don't see any particular emphasis placed on the display panel in a notebook's specifications it probably has a panel similar to one of the laptops we're looking at today.
