Have a $1,000 budget for a new notebook? Look no further than the ASUS M51S. Touted as a multi-media notebook, it offers a 15.4" screen, 250GB HD and 3GB of RAM. Included also are 4 USB ports, DVI and VGA outputs, full numpad, fingerprint reader, a face-detection logon system and more.

Battery Life, Performance & Gaming Tests


Our testing methodology for notebooks is rather simple. Depending on whether it’s high or low-end offering, we choose our benchmarks and tests accordingly. If a notebook is designed for business, for example, we don’t run games on it (unless it has a capable GPU that hints that gaming should be done). Most of our benchmarks are real-world, but we do use SYSmark 2007 Preview and PCMark Vantage for synthetic system-wide performance analysis.

We currently have no basis for comparison performance-wise, since we haven’t published a notebook review in a little while (that will change), so I apologize for delivering results that might not mean too much right now. If you have a notebook and are thinking of upgrading, you could use these for comparison that way.

In the table below, we list all of the tests we conducted. “EFS” in our DivX test represents “Experimental Full Search”, which is an advanced algorithm that thrives on the SSE4 instruction set. Once we have a notebook in with a Penryn CPU, we’ll be able to see the benefits there.

The results are not jaw-dropping, but given the price-range and CPU used, I didn’t expect anything else. Having a faster CPU would make a large difference in almost all of these tests. As mentioned earlier, the newer revision of this notebook contains a processor that’s 170MHz faster, so all of these results would be heightened a bit had I been given that revision for review.

Battery-Life

As we would expect, the M51S does not excel with superb battery-life. With the help of MobileMark’s productivity suite, we calculated that during regular work use, the notebook will last upwards of 1h 49m before dying. That’s assuming that you turn the notebook off at the 5% battery-life remaining mark.

Watching a DVD shows even worse performance, with a manual test of playback lasting us 1h 26m. Not impressive, but again, not unexpected. Even higher-end notebooks don’t improve on battery-life too much.

Gaming Performance

Because notebooks come in a wide variety of shapes and sizes, we don’t benchmark games in the traditional sense, as we would with an actual gaming PC review or a review of a desktop graphics card. So, we don’t report our average FPS, either. Instead, we load up four different titles and play through a selected intensive level and adjust the settings until we find one that makes the game fully playable (no lagging or outright stalls).

Our immediate goal is to run the game at the notebooks native resolution, and if we have to, then we’ll lower it in order to make a game playable. Most often, though, games can run at native resolutions with weaker texture settings, which we prefer over lowering the resolution. Non-native resolutions do not look good on LCD panels.

Below are reports from the four games tested, with both the actual screenshots of the settings used, and also a direct screenshot from the game to show the detail of those chosen settings.

Each gameplay screenshot has an FPS counter from FRAPS in the upper right-hand corner, which represents the FPS we saw at that exact moment, which might give you an idea of overall performance. We don’t recommend judging real performance by that number, however, since 20FPS might be playable in one game, but not in another. So with that said, none of these settings were “barely” playable. All of them were 100% playable without any real lag.

Half-Life 2: Episode Two

Unreal Tournament III

Need for Speed: Pro Street

When looking over the notebook specs, I didn’t expect to see much in way of gaming performance, but I was wrong to doubt the NVIDIA 9500M GS. Each game tested ran well, and looked good, all at the same time.

I am impressed by the gaming performance of the M51S. We might be dealing with a small resolution (1280×800) and had to keep moderate texture settings, but in the end, the games looked good (they actually seem to look better on the notebook itself than the screenshots prove) and performed well.

What impressed me the most, however, was that even after longer periods of playtime, there was not a single hint of lag during any part of the gameplay, not once. The notebook has some great airflow, because most notebooks tend to overheat when their GPUs are put to good use.

That said, let’s get right in my final thoughts on the next page.
