Internals & Performance

Overall, the Aspire TimelineU M5-581TG-6666 is a solid performer, as you might expect from a dual-core Ivy Bridge processor, a GeForce graphics chip and 6GB of RAM. As you'll see in the results below, the M5 wrecks the Folio 13 and other notebooks we've tested when it comes to graphically-intensive tasks.

And yet, it feels slower for everything else. The M5 has a 500GB 5400RPM HDD but relies on 20GB of flash and Intel's Smart Response Technology (SRT) to boost performance. This is evident when resuming from hibernation, but general usage (launching apps and such) is noticeably slower than a true SSD.

Personally, I'd rather drop the DVD drive and put the savings toward a 120GB mSATA SSD for Windows instead of relying on SRT. Unfortunately, Acer's TimelineU series doesn't seem to offer anything like this and you'll have to completely disassemble the machine if you want to take matters into your own hands.

During heavier loads (especially gaming), the M5 got very hot on the bottom and I wouldn't want it directly on my lap while performing such tasks, especially not during the summer. However, I think this is somewhat of a given considering the specifications and I wouldn't necessarily dock points for it.

Acer estimates the battery life at eight hours. During our usual torture test (looping a 720p rip of Inception with the hardware maxed), the system made it just shy of five and a half hours. Achieving seven or more hours seems feasible with power saver settings and lighter usage.

The iTunes encoding tests consist of converting 14 MP3s (119MB) to 128Kbps ACC files and measuring the operation's duration in seconds. For file transfers, we measure how long it takes to copy two sets of files from one location to another on the same hard drive. On the small files test we transfer 557 MP3s, totaling 2.56GB. For the large file, these same MP3s were zipped into a single file measuring 2.52GB.
