MacBook Pro Gets Santa Rosa Chipset, LED Screen
frdmfghtr writes "TechNewsWorld is reporting that Apple has updated the MacBook Pro line with the Santa Rosa chipset from Intel. In addition, Apple is also introducing mercury-free displays with some models. 'When Apple presented new editions of its MacBook line last month, the company excluded the latest Intel Centrino chips, dubbed "Santa Rosa," which had been released just days prior. The chips have found their way into Apple's new high-end MacBook Pro notebooks, which the company revealed Tuesday. Certain models use mercury-free displays, falling in line with the company's recent ecological promises.'"
...a link to the actual MacBook Pro web page and specifications, since that's what people here probably care about, as opposed to a "TechNewsWorld" article being the only thing linked in the summary?
Also, while Apple folks and other tech-savvy folks may know the Intel-based Macs run Windows, why does the news article not even mention that? For many people even considering buying a Mac, the fact that a laptop like this can easily run Windows natively or seamlessly alongside Mac OS X with packages like Parallels Desktop at least bears repeating.
30-40 minutes estimated additional real battery life for the 15". Although apple isn't saying if most of the additional power saving is coming from the LED-backlit screen.
Rubies and Pearls are not what you think.
I've got an early '05 Powerbook G4 (first-gen HD motion sensors represent!). It's a great little thing but as I do more photo editing and such I'm starting to feel it's lack of power. I've used Intel Macs with C2Ds and they are very nice. I decided that during the next refresh I would purchase one.
So when I checked the Apple store yesterday and saw it was down, I was thrilled. I had been expecting it (I follow rumors sites and Apple Insider had some detailed possible specs on Monday). When I got to work the store was back up and I ordered one immediately.
It's about time that Apple put 2 gigs in the MacBook Pros by default.
It's expected to come as soon as Friday, and I can't wait. Geek Sugar has pictures of the new one, and they that the display is noticeably brighter, despite the fact it's not supposed to be (according to Apple, there is a mini-interview on Gizmodo).
I can't wait!
Now I just need Leopard...
Comment forecast: Bits of genius surrounded by a sea of mediocrity.
I am very interested in this as well, and have been looking around various photo forums for the past few weeks (in expectation of this announcement). The general consensus seems to be that the color gamut is superior on LED displays than traditional ones; whether this first generation one will work this way we'll have to wait and see...
However, from what I understand, the iPod screens have been LED based for some time; while I don't have one myself, from what I've seen the colors are very nice on them.
Take that as you will 8-)

I presume LED in this context means an LED based backlight, backlighting an LCD screen right is pretty difficult, whatever light source is used it must provide illumination with a suitable wavelength makeup and have its light spread evenly accross teh screen.
the normal way to do this is with a very thin mercury floursencent lamp that runs along the bottom of the screen and then some clever optics that spread the light vertically.
LEDs tend to concentrate thier light at a point rather than along a strip which i would imagine makes spreading the light much harder. White LEDs also tend to have an unusual spectrum which may be an issue too.
note: i'm known as plugwash most places but i screwd up registering that here somehow in the past and now can't register
The big thing is that it will let the macbook pro address a full 4gb of RAM. In the previous revisions only 3GB could be addressed. I'd imagine there are also other power/performance improvements.

Colour accuracy and laptop LCDs do not go hand in hand
Um, no...
Laptop screens have been very capable of fairly accurate color for quite a while. This might not be true of the last gen Macbooks that had 250K displays, but for most people in the graphics world, we buy the high end screens on our laptops and can do just as accurate color as when sitting at a desktop display. (Even go back to the Theater displays from Toshiba in 2002 1600x1200 on a 15" screen with a fairly high contrast ratio, refresh speed, and more than a simple 16 or 18 bit display.)
I know these resolutions and quality is unheard of in the Mac notebook world, but is pretty common on any laptop in the PC world for over 5 or 6 years now.

The LEDs do just provide the backlight.
The color spectrum that a given LED provides will necessarily be different than the spectrum that CCF backlights generate, and different from the spectra that the various CRT monitor phosphors generate.
If a given portion of the spectrum is not present in the "white light" (using that term very loosely here) backlight, no amount of filtering by the LCD screen overlay can put it back. If this is not intuitive, imagine trying to create blue using only a pure-red LED backlight. (You can't do it - the backlight must have at least some blue).
So if, for example, the LED backlight has more green and red light available in its "white light" spectrum than a CCF backlight has, the LCD overlay so-illuminated can produce yellow tones (since red and green are the constituent primaries that make yellow) that a LCD illuminated with a CCF cannot. That gives the LED-illuminated LCD a wider gamut.
However, if both the LED-illuminated and the CCF-illuminated LCD overlays only filter light at a resolution of 8 bits per channel, they will both be able to display the same amount of information about color, but because the gamut of one is different from the gamut of the other, in many cases they will not be able to display the same colors.
The "6-bit" comment in my earlier post refers to the fact that Apple has been shipping 6-bit displays on its Powerbooks and MacBook pros for a while. I believe there has been a /. post on this situation.
If a manufacturer provides more bit depth (more than 8 bits per channel, f.e.) the LCD overlay will be able to filter the available light more finely than 8- or 6-bit displays can do. In general, an 8-bit display should in fact have a larger (but not necessarily wider) gamut than a 6-bit. A 10-, 12-, or (allow me to dream here) 16-bit-per-channel display would have still larger (but again, not necessarily wider).
In an LCD display the spectrum of the backlight will determine how wide the gamut can be at its absolute maximum - if a color is not present in that spectrum, it cannot be filtered into existance by the LCD overlay. By the same token, the bit-depth-per-channel of the LCD overlay will determine how many individual color tones are in that gamut.
In reality, it's a lot more complicated than this, but this is the gist of it.
That's a very backward-looking comment. Going forward, more and more developers may rely on Hardware T&L that the GMA950 doesn't support but most other cards, including Intel's newer integrated graphics, do. 3D will not be "just for games" for much longer. (And a previous poster noted that already a 'casual' game from 2005 -- Civ 4 -- relies on Hardware T&L not for performance but just because the developers relied on its presence; if it's not there, it won't work. Developers are coming to expect its presence.)
A few examples of every-day applications that might expect Hardware T&L in a year or two: Better 3D mapping applications; Mocking up corporate display stands and being able to see what they'd look like assembled; designing your kitchen; 3D cooking animations to explain the method of a recipe, etc.
In fact, the 3D maps is going to be the killer: MS Research and Cambridge Uni have already developed systems that can calculate building geometry from photos taken at different angles; Google Streetview has an awful lot of photos of buldings taken at different angles. Care to guess how quickly a fully-walkable Streetview Map relying on some of the 3D features of your video-card will take? (A 'better' Google Earth or MS VirtualEarth that uses hardware T&L and photo data to give a less 'warped' view...)
So, if you want your laptop to be able to work with interesting non-game software coming out in 1-4 years' time, that GMA950 could be a right pain.
Color gamut reproduction is a function of two things:
1. the red-green-blue filters used in the LCD
2. the quality of the backlight.
Yes, you can create two whites that look identical (same x,y coordinates and therefore color temperature) but have different gamuts. LEDs offer a highly saturated green (and, to a lesser extent, a saturated red). If the filters pass these saturated colors, then the display will look much more vibrant. If you've seen an LED-lit tv in person, the difference is pretty obvious... of course, it all depends on the filters, so I don't know if apple has expanded their gamut.
Yes, I'm somewhat of a color expert. I designed the equipment that calibrated millions of LED-lit LCD displays for my company.
