We've known about Cedar Trail for quite a while now, the next iteration of Intel's Atom processor line. As far as the CPU is concerned, not a lot has changed from the previous generation Pine Trail. Cedar Trail is manufactured on Intel's 32nm process technology, but the CPU architecture is still in-order. You can read more of our Cedar Trail coverage in our initial look at the platform. It's taken far longer than expected, but we finally got someone to send us a Cedar Trail netbook for review. That someone is ASUS, and the netbook is their 1025C.

We'll have our full review in the future, but in the meantime we thought we'd give some quick impressions of performance and, more importantly, battery life during video playback. I'll cut straight to the chase with regards to CPU performance: it's largely unchanged from the last version, which means Atom N2600 still feels quite sluggish for many tasks. Atom is faster than ARM A9 CPUs, and you can see a comparison of Sunspider 0.9.1 with various tablets below, but for Windows 7 it's still painfully slow at times.

The bigger change however is in the GPU, where the old GMA 3150 (itself a minor tweak to the even older GMA 950) is finally getting a needed upgrade. This won't turn Atom into a gaming system by any stretch of the imagination, but it does finally bring GPU accelerated H.264 decoding into the Atom ecosystem (without the need for a discrete GPU). What does that mean for performance? It means HD YouTube video can finally run without dropping a ton of frames—at least, the 720p videos that I tested played back without any major issues. 1080p video still experiences quite a few dropped frames, unfortunately, but then you don't need to stream 1080p video if you're using the integrated 600p LCD.

But YouTube HD video has always demanded more than local video playback, and we can now finally get DXVA assisted playback of H.264 video content. I tested both 720p and 1080p H.264 videos without any major issues using MPC-HC. What's more, I ran our standard H.264 battery life test to see how the Atom N2800 fared—and I ran it a second time with a 1080p video stream just for good measure. Check out the results:

Video Playback - H.264 720p

Atom and netbooks in general still aren't going to set the world on fire with performance, but if there's one thing Atom can do well it's long battery life. Cedar Trail takes the previous Atom results and improves on them by over 50% in video playback tests. Tablets still generally do better here, but gIven that Cedar Trail now supports HDMI output, you could conceivably use an Atom netbook as a portable media player in addition to standard laptop tasks.

I tested Hulu and Netflix on the 1025C as well and both worked reasonably well, but only with SD content. That's not an issue for Hulu, but Netflix HD content completely lost A/V sync. It may be that Hulu and Netflix are not currenlty recognizing the GMA 3600, but until this is addressed it's worth noting.

There's still a question of whether a $300 netbook has a place in the market when we've got tablets to play with, but it's really a matter of intended use as well as price. ASUS' own Eee Prime Transformer offers a better display and a nifty touch interface that easily surpasses the Windows 7 Starter experience, but if you're looking to do mundane tasks like basic word processing you'll need the keyboard attachment, which takes the final price up to ~$550—nearly twice that of the Eee PC 1025C. For basic typing, then, the price of the 1025C makes it a better choice, and you get excellent battery life that will easily carry you through a day of use and then some.

Atom still isn't going to surpass AMD's Brazos for performance or GPU driver quality, but pricing and battery life still appear to be in favor of Intel's Atom, and 10.1" Brazos netbooks are pretty rarefied. We'll have our full review as soon as we can finish running the remaining benchmarks and doing additional testing, which might be a while. Hopefully we'll see equally impressive improvements for Internet and Idle battery life, but it took over ten hours to recharge the battery on the 1025C and eight hours plus for our video playback test, so basically I'm look at a full day for each battery test cycle to complete.

    So a buyer is still getting a slow CPU from 2008 with updated GPU that can finally run Youtube videos without stuttering. Amazing Intel... Reply

    It's not a matter of "all they can do" -- look at Core 2, Arrandale, Sandy Bridge, and soon Ivy Bridge. It's more a matter of "this is all Intel is willing to do for the sub-$50 CPU/SoC market". They're so afraid of cannibalizing sales of higher end chips that they refuse to release a real competitor to ARM. If Intel really wanted to make an amazing ARM competitor, they could, and we might see that at some point. The problem is that ARM SoCs like Tegra 3 and Krait sell for around $25, maybe $40 at most. Intel wants that 60%+ profit margin, and even they can't make an SoC that outdoes ARM for a cost of $15 to $25 per chip. Eventually, ARM chips will force Intel to do more for less...or possibly we'll see ARM chips that do more and cost more. A5X certainly isn't all that inexpensive I'd wager. Reply
