So even if it is not retina calibre but higher resolution than what is available today, you are saying that by boosting VRAM will suffice to drive the display without any problems? In other words, will it be possible to run games in native res without compromising performance is the screen res is boosted in the 2012 lineup?
I am saying that for 2D the GPUs have enough pixel pushing power.
For 3D stuff like games you can run non native resolutions. Non native looks bad if the two resolutions are very close to each other but if you have something higher than 1080p you can just run 1280x720 for enough performance in pretty much any game and it looks pretty much like native.
The higher the resolution the better the scaling. Retina like Resolution and nobody can distinguish the scaled res from a native res in the same proportions.
1366x768 does look exactly like a native 1366x768 res when it is scaled on a retina display. Thus you don't loose anything you just finally have the freedom to choose your preferred res just like it was in the CRT days.
No GPU that you can put in a notebook in the next 2 years can handle a 15/17" retina displays native resolution in modern games.
VRAM is like RAM. Give it enough and you close a bottleneck. Apple always used to supply to little VRAM. Even in 2D with 2 screens performance sucks once you have to many windows open. They should finally up their game and put some serious 1GB minimum into their notebooks that stuff is fairly cheap anyway. Better yet 2GB.
It won't solve a performance issue it just stops one from occurring.
Currently you can drive 2x 27" monitors on one notebook, obviously that means it can handle a retina display.
Still there won't be any because that display is expensive and I think it takes at least one more year maybe two. Apple already has some of the best notebook screens. Granted they are still rather poor compared to good desktop panels and only one of the best because most notebook screens are crap, but still I don't see how it would really pay off.
If they promote it with their retina brand many of the fool buyers might finally figure out how bad most displays are. Would be good marketing. The difference between the average notebook screen and theirs would finally be obvious for everybody.
They are aiming for it definitely but they are constrained by technology. If Samsung cannot produce such a panel for a reasonable price it just won't show. Tablets are different the panel already makes almost 50% of the entire manufacturing costs. Even the comparably good MBP panels are just okay TN Panels. That is a bigger step up.
Apple will laid the ground work but they will sit it out until it is possible.
What many fanboys and Apple freaks don't realize is that Apple always just did what current tech allowed and was maybe a few months ahead of the competition. IPhone like smartphones would have popped up anyway. Tablets with smartphone tech instead of notebook tech have always been just a matter of time.
Apple is the big tech giant because it was always a bit ahead not because it introduced something so fundamentally different than what other companies would have come up with given the general tech developement.
And also because they ignored the cheapo mainstream and thus could reap the benefits of a better reputation.
