ASUS N53JF: Midrange 15.6” 1080p, Take Four
by Jarred Walton on December 28, 2010 1:40 AM ESTASUS N53JF: Performs as Expected
Performance is pretty much right where you’d expect, given the hardware. It has the same GT 425M GPU as the Clevo B5130M and the i5-460M CPU is fractionally faster than the i5-450M in the XPS 15, so performance typically falls in between the two. Battery life is somewhat hampered by ASUS’ continued use of 48Wh batteries in their N-series, something we’ve complained about in the past. The U-series’ 84Wh batteries don’t feel much heavier than the 48Wh, and size is close enough that a slight reworking of the N53JF could have accommodated the larger battery. However, ASUS does do a reasonable job at power management, so even with a smaller battery than the competition it remains competitive. Here are the application results, followed by gaming and battery life.
Starting with these general performance metrics, the N53JF is usually about 5% faster (sometimes as much as 10%) than the XPS 15, which goes with the CPU upgrade, with perhaps a few extra performance optimizations by ASUS. The Clevo and Compal laptops both have a faster i7-640M CPU so they come out ahead, but other differences come into play. In PCMark, the Clevo and ASUS laptops are nearly equal, but the Compal comes out 13% faster in Vantage and 23% faster in PCMark05—perhaps thanks to the HD 5650 discrete GPU. Once we hit the pure CPU tests of 3D rendering and video encoding, the charts fall into line and the i7 CPU outpaces the i5-460M by 8-10%.
3DMark numbers aren’t a major focus for us, for good reason. Here we see the N53JF leading by up to 22% in 3DMark06, but then it trails by up to 15% in Vantage. Yeah, go figure. The Performance score in Vantage is 3559 for the curious. The 3DMark03/05 numbers aren’t any better (no graphs on those): 16612 in 03 and 13397 in 05 put it slightly ahead of the Clevo and Dell laptops, but the HD 5650 is 3% faster in 05 and 30% faster in 03. The reason for the large lead in 03 is that Optimus appears to be a bottleneck on ultra-high frame rates; the PCIe bus gets saturated, so when you start to try and push more than ~150FPS (i.e. in the Wings of Fury benchmark) you hit a hardware frame rate bottleneck. Given the level of hardware and the frame rates where this manifests, however, it’s nothing we’re concerned about—it should only show up in older titles that really don't stress the GPU much.

I wouldn't hold my breath. The theater's originally went widescreen (1.85 in the US, 1.6 in the EU) to differentiate themselves from the 1.33 aspect ratio of TV and offer something more than a giant screen to compensate tor the extremely expensive food and obnoxious idiots you had to share the theater with.1.85 isn't much more than 1.77 and with 3D poised to invade the living room as well it won't serve well as a differentiator. Unless the studios decide to throw the theaters under a bus I expect something wider to go mainstream even if they stop short of 2.39.

The end has begun, Vizio just launched a pair of 2.33:1 TVs at 2560x1080. I hope everyone is looking forward to their 2013 laptop running at 1400x600. It won't be deep enough to have a touchpad, so your lousy low contrast ultra-superglare LCD will be covered in fingrerprints from the touchscreen layer.http://ces.cnet.com/8301-32254_1-20027127-283.html

The 1080 resolution was a standard HD resolution in the 80s and 90s, long before flat-screen, fixed-pixel displays were even being sold.While you may argue that 1080p is a step backward in resolution from the 1600x1200 CRTs of yesteryear - not even my beloved (and perfectly calibrated) Sony FW900 24" CRT can hold a candle to the clarity of my 1080p LCDs. Not to mention the LCDs are thinner, lighter, and much cheaper. Plus, having a true 1:1 pixel ratio for HD content is so much better. My wife is a professional video effects editor and can attest to the benefit of 1080p displays for her own reasons as well.
That's progress.
The only regress I can think of with modern displays is the loss of refresh rates over 60Hz. That's the only reason I keep the FW900 - for gaming w/VSYNC @85Hz and up. Analog FTW in that case. More and more 120Hz and 240Hz LCDs are coming out, but without proper mainstream connectivity, what's the point? Meh to that.

I agree that in some respects current displays are better than what we had ten years ago, but some things took a step back, and even if everything else was equal, it's not such significant progress. If I want a monitor that's better than 1920x1200 I need to pay a lot more than I did for the 1600x1200 19" monitor I bought 8 years ago, and it'd be a lot larger.One would have thought that by now it'd be possible to display high quality text and images on a PC monitor, but somehow we've degenerated into believing video is the only application that matters.
I agree that for standard users, who do just web and content surfing, current monitors are a step up from what they had in past years (1024x768, 1280x1024), but anyone more demanding could ten years ago get something that was a step up yet took about the same space and didn't cost 5 times more.

Yup, what DanNeely said is right. Even with Blu-Ray, which represents the highest data rate currently available for consumer 1080p video (roughly twice what you get with terrestrial HD broadcasts, which in turn have higher data rates than cable, satellite, hulu, and netflix), the signal has to be compressed an amazing ~100:1 vs. a raw video feed! Only the cleverness of the compression algorithms, combined with the fact that large parts of a typical picture don't change much from frame to frame, allow this compression to still look good ---though it is still perceptually lossy on a high-end system (I understand Joe Kane did some studies to determine what data rate you would need to avoid all perceivable compression losses, but the results were for a private client and thus not published).Plus don' t forget that the current bandwidth limitations force compromises not just in spatial resolution, but also chromatic and temporal resolution. Blu-Ray movies today have 8-bit color (allowing for only 2^8=256 gradations). The standard does allow for higher color depth (up to 16 bit), but that means more data and, with the current bandwidth limit, that in turn would necessitate more compression. Likewise, at 60 fps we'd get more temporal resolution than we do at 24 or 30 fps, which would result in less blurring during fast action scenes. But if you go to 60 fps, you've got to give something else up.
I.e., with the current bandwidth limitations, we're at about the limit of how much spatial resolution the system can offer, unless we want to increase compression artifacts or give up further on the already-compromised chromatic or temporal resolution.
Don't get me wrong -- I have a 100" screen (JVC RS1 projector), and would love to see a consumer 4K format. But I'd also like to see at least a 12-bit 4:4:4 color space, and fewer compression artifacts---which is not going to happen until they can offer a bandwidth about an order of magnitude higher than what Blu-Ray currently offers.
And unfortunately, a lot of video seems to be moving in the same direction as music -- less resolution for more convenience. So I think it may be a while before we see market pressure for a higher-resolution video format.

We also appear to be reaching the limits in what compression can offer. Over the summer I read that the team working on the H.265 algorithm were concerned that they'd only be able to reduce bitrates to 70% of current levels while maintaining quality levels vs the 50% target that they'd set when beginning the design process.torgal - Tuesday, December 28, 2010 - link
Well, and now Dell XPS 15 no longer have the 1080p upgrade (http://www.dell.com/us/p/xps-15/fs). Or have I got the wrong XPS 15?jigglywiggly - Tuesday, December 28, 2010 - link
hai guise my name is asus we make a good laptop and then ruin it by putting a POS LCD on it.Kaboose - Tuesday, December 28, 2010 - link
I think with sandy bridge on the horizon the majority of the people this laptop seems to be targeted at would be better off waiting a month or so for something more substantial for their ~$1000.jabber - Tuesday, December 28, 2010 - link
Surely it doesnt take 1 minute to wipe a product down before taking pics of it?Just makes it seem a little more pro.
