Intel Core 2 CULV Roundup: Who Needs Atom?
by Jarred Walton on February 4, 2010 4:00 AM ESTGeneral Performance: Atom Gets Dusted
We've shown most of these results in our ASUS 1201N review, but where we were comparing dual-core Atom 330 to Atom N280 and N450, let's now focus on CULV performance. Starting with PCMark, we immediately see a very large performance gap. This isn't some synthetic divide, either: you will very much notice the performance boost moving from Atom N450 to the 1201N, and you'll feel it even more if you compare CULV to Atom N450. Even the Atom 330 is still a big drop in PCMark Vantage, where it's 35% slower than the EC5409u. PCMark05 shows a smaller difference of around 17%, but PCMark05 is relatively outdated now (as the 2005 year indicates).
Next up we have Internet Surfing performance measured by the Futuremark Peacekeeper benchmark using Firefox 3.6. Peacekeeper is single-threaded in nature, taxing only one CPU core, but this is quite realistic for many non-video websites. Here the Atom 330 is hurt by its lower clock speed relative to N280/N450, and the jump to CULV roughly doubles performance. If you tend to surf simple text/image sites, the gulf may not be quite so large, but on most modern websites there's a clear difference between rendering times on Atom compared to CULV.
Similarly, CINEBENCH allows us to show quite clearly the difference between single-threaded and multi-threaded tasks. In single CPU mode, the CULV laptops are about 2.5 times as fast as Atom - N280, N450, or 330 doesn't matter. In tasks that can use multiple threads efficiently, the gap between CULV and Atom 330 closes a bit. CULV is still nearly twice as fast as the 330, but it's also 3.35 times as fast as N450. Remember that the multi-threading on N450 is actually Hyper-Threading (SMT) rather than two complete CPU cores, so this is expected.
Wrapping things up with some heavily threaded video encoding tests, the four threads on 330 can at times come close to a 1.3GHz CULV. The best result is in DivX encoding where the 330 is only 4% slower than the various CULV laptops. x264 is more strenuous and the CULV offerings are 30~40% faster than Atom 330. Meanwhile, the "new and improved" Atom N450 shows only a very small improvement relative to N280, with CULV still delivering about 2.5 times the performance.
So as you would expect, the performance comparison between Atom and CULV is a lopsided affair. Atom is about keeping costs and power requirements low, and performance just isn't a major concern. Yes, it can run Windows 7, but you wouldn't want an Atom-based system to be your primary computer if at all possible. Given the pricing, you also wouldn't want to spend much over $300 unless you really like some of the other features on an Atom netbook (e.g. perhaps the chassis and build quality are a lot better than the competition). For the most part, Atom wins the price wars, but what about power and battery life?

Still waiting for a review unit. I am also curious to see if Alienware allows overclocking, similar to the ASUS UL series. If they do, and with the GT335M, the m11x is going to be a very speedy machine in many respects. Of course, it's going to cost close to $1000 I imagine, but the features will probably make it worthwhile.synaesthetic - Friday, February 5, 2010 - link
There is a BIOS option to overclock the FSB on the M11x. According to the review, the SU7300 was overclocked to 1.6GHz with a respectable boost in performance and a negligible increase in heat (only a degree or two hotter).yyrkoon - Thursday, February 4, 2010 - link
I could not get past the brand name personally. Many people out there do their best to avoid the "greatness" that is Acer. I am just one of those people.clarkn0va - Thursday, February 4, 2010 - link
Maybe my information is just out of date, but my knowledge of the Acer Timelines differs somewhat from the information presented in this article.For starters, Jarred is stating that they have plastic covers. I own a 3810T and the cover is brushed aluminum (or a really good fake), thank goodness.
Secondly, it was my understanding that (at least some of) the TZ models had switchable graphics, enabling the user to switch from Intel to AMD graphics on the fly. Perhaps this isn't offered any more.
Lastly, and this is not Jarred's mistake, just an unfortunate reality, mine came with an 80GB Intel G1 SSD. This not only improves performance markedly, but should help to extend battery life. I think it's a shame that more desktops and laptops don't include this option.

I was going to comment on this too. There are A LOT of differences within each Timeline series. I know there are 1810T's with aluminum rather then the plastic, and the new Olympic editions are very nice.Personally I own the 1810T (black plastic with SU7300) and couldn't be happier with it. It does have some of the problems Jarred listed, but you quickly adjust to the size of the trackpad; I haven't had any issues dragging things around the screen.
My brother owns the 3810T (Brushed aluminum w/ SU7300), and it is much more polished then the 1810T (blakc plastic). The little extra size really helped Acer make it a much nicer laptop. Even his keyboard is of a different material/style then mine. The touchpad is also different. He got his only a couple weeks after me, and I gladly would have taken the slight extra weight for the updates it had to everything else had I known.

If I'm not mistaken (and I admit, I might be -- curse Acer and their plethora of SKUs that are all very similar!), the aluminum Timeline models are more expensive than the plastic models. At a price of around $750 to $800, I'd go with the ASUS UL80Vt and get switchable graphics. The Olympic Edition of the 1810 does look very nice, but can anyone confirm that it's truly aluminum? Look at http://www.newegg.com/Product/Product.aspx?Item=N8...">these pictures and it appears to be glossy plastic to me. Still, it's got the right parts and price ($550), if you're okay with the keyboard action.jabber - Thursday, February 4, 2010 - link
I'm a convert! Since I got my Inspiron 13Z with its 7300 it's been great. Similar grunt to an old P4 2.8Ghz dual core with a Nvidia 105 GPU and 4GB of ram.For a small laptop its perfect. Plays games just fine and if I set it to balanced power it can run for 8 hours+ easily.

I hope not to start a flame war or cause any hard feelings or upset on Jarred's part, but I feel it's worth pointing out that this piece could have really used a polish. One of the great things about AT is that the coverage and the writing have always been equally high in quality. Certainly, the occasional typo or awkward sentence would sneak out, but on the whole it could be trusted that the articles read as if they had been reviewed by an editor.This article, however, did not feature the typical AT polish; a fact which was evident in the very first sentence:
"A couple years back, ASUS released the first netbook on an unsuspecting world."
While a conversational tone is certainly appreciated, the absent 'of' between the second and third word mar this sentence. The opening paragraph continues with several sentences which reach or border on being run-ons; and could easily stand the presence of a few semi-colons. Typos and word misuse ("differentiator" is a specialization mechanism in cell biology, and not a general term for the variable that separates members of a population) litter the first page, and would no doubt have been caught by a copy editor.
Again, I am absolutely a fan of this site and the wonderful articles produced here. Letting mistakes like these slip past, however, diminish the articles to the level of blog posts and not quality technical journalism. As the number of writers and staffers grow, it becomes harder to enforce high writing standards. If it hasn't been done, perhaps it's time to consider hiring some proof readers?

QuietOC - Thursday, February 4, 2010 - link
Haha, Jarred lifted some of that wording from a sample review I submitted to them: "A few months later ASUS released the original Eee PC on the unsuspecting world market." There's nothing particularly unique about the language. I wouldn't be surprised if I unconsciously borrowed it myself.JarredWalton - Thursday, February 4, 2010 - link
The use or omission of the word "of" in the first sentence is entirely a stylistic preference. "A couple years ago..." or "A couple of years ago..." mean the same thing, with an extra syllable in the latter. As for differentiator:http://www.thefreedictionary.com/Differentiator">differentiator - a person who (or that which) differentiates.
I am using it as the latter, and it is correct in that sense. Sorry if I view the English language as more fluid than others, but I have no qualms about playing with words as I see fit. I would hope most people are more interested in the technical content than whether or not I follow the MLA guidelines.
If you really want to complain about my writing style, you'd be far better off saying that I have a bad case of word diarrhea, IMO. I write far more text than I often feel is necessary, but then if I omit certain aspects of a review I always get someone complaining that I "didn't talk about feature xxx". Another potentially valid complaint would be my use of parenthetical comments and phrases set off by dashes--and I'm sure I use dashes incorrectly at times! ;)
