Just after the launch of the Retina MacBook Pro earlier this month,
AnandTech provided a first glimpse of the machine's display performance,
noting the various resolution options available to users and examining how
its color and contrast compares to other notebooks.
After having more time to analyze the new machine, AnandTech last week
published its full review of the Retina MacBook Pro, bringing its thorough
and technically-detailed perspective to the report. While the whole review
is definitely worth a read, the section on graphics performance bears
special attention.
With the integrated Intel HD 4000 and discrete NVIDIA GeForce GT 650M
graphics units responsible for driving 2880x1800 pixels in standard Retina
mode and as many as 3840x2400 pixels before downscaling to display 1920x1200
at its highest non-Retina resolution, Apple is clearly pushing the limits
of the machine's graphics capabilities.
At the default setting, either Intel’s HD 4000 or NVIDIA’s GeForce GT 650M
already have to render and display far more pixels than either GPU was ever
intended to. At the 1680 and 1920 settings however the GPUs are doing more
work than even their high-end desktop counterparts are used to.
AnandTech goes on to assess this graphics performance, noting that the
Retina MacBook Pro at times struggles to maintain a "consistently smooth
experience".
At 2880 x 1800 most interactions are smooth but things like zooming windows
or scrolling on certain web pages is clearly sub-30fps. At the higher scaled
resolutions, since the GPU has to render as much as 9.2MP, even UI
performance can be sluggish. There’s simply nothing that can be done at
this point - Apple is pushing the limits of the hardware we have available
today, far beyond what any other OEM has done.
Focusing on browser scrolling behavior, which also involves substantial CPU
load, AnandTech notes that the resource-intensive Facebook news feed pages
can display at over 50 frames per second on a 2011 MacBook Pro, but that the
new Retina MacBook Pro struggles to hit 20 frames per second as it pushes
so many more pixels.

The report notes that OS X Mountain Lion will help address some of these
issues by leveraging Core Animation, but in AnandTech's testing it was still
only able to achieve 20-30 frames per second under Mountain Lion. Further
improvements in performance will have to wait for hardware capabilities to
catch up with demands imposed by these new ultra-high resolution displays. |

那个死样，大家嘲笑APPLE，我为了RETINA的屏，买了TOUCH PRO 2。没想到12年，
APPLE把LAPTOP搞成RETINA了，其它的厂商还在做梦 |

I have the impression that apple did the first "retina" level screen on
smartphone.

Retina display is a brand name used by Apple for displays claimed to have
pixel density so high that the eye would not be able to notice pixelation at
a typical viewing distance.
就是说在一般视距内眼睛察觉不到屏幕上的pixel，就算达到retina屏幕的标准了。在
RMBP上，每英寸的pixel是220。在Touch Pro的3.6寸屏上的WVGA(259ppi)也达到这个标准
了。。。

粒，再往上加也是浪费，反正眼睛察觉不出区别。

display just means high end display. but the standard reference line is set
since and according to iPhone 4.

发帖数: 8347 | 17 嗯，标准也就是做个参考吧，最终感觉怎么样要因人而异。有人觉得ipad 2和new pad
看上去没太大差别，也有人觉得看了new pad，再看ipad 2就像患了白内障。
不过将来果子要想再在加高resolution上升级的话，就要动下脑筋怎么justify了，因
为它已经声称现有的retina屏幕上眼睛察觉不出pixel颗粒，那么再往上升级的意义何
在？
