New iMac updates from Apple

Almost coinciding with the iMac's 10th anniversary, Apple has just released an updated version of their most popular computer. As updates have been appearing steadily in the last few months, it was expected that Apple would introduce some changes to one of their best-selling product lines.




As with the previous incarnation, Apple has maintained the sleek aluminium and wrap-around glass case, in the same dimensions, 21.5 and 27 inches. But now, all iMac have received a LED backlight update, as well as the introduction of IPS to a larger display. IPS, or In Plane Switching, is one of the technologies developed for the iPhone 4, which was deemed of high enough value to warrant its inclusion in desktop computers. IPS increases the angle of view of LCD monitors, allowing a similar quality of image whether from the front of the display or off to the side, providing a viewing angle of almost 178 degrees vertically and horizontally. Another interesting feature concerns  specifically the 27 inch models; the screen resolution has been increased from the default 1920 x 1050 to a whopping 2560 x 1440, a 78% increase in number of pixels between a 27 inch and 21.5 inch display.




The display improvements don't end with the actual panel. Apple has chosen to upgrade the graphic processor, providing users with two choices, either the ATI Radeon HD 4670 with 256MB of dedicated memory or the ATI Radeon HD 5670 with 512MB of dedicated memory. But for the 27 inch model, the choices are even better. The same ATI Radeon HD 5670 with 512MB of memory or the ATI Radeon HD 5750 with 1GB of GDDR5 memory. As a side note on graphics, all iMacs now feature:

  • Mini DisplayPort output with support for DVI, VGA, and dual-link DVI (adapters obviously sold separately); 27-inch models also support input from external DisplayPort sources (adapters obviously sold separately)
  • Support for extended desktop and video mirroring modes
  • Simultaneously supports full native resolution on the built-in display and up to a 30-inch display (2560 by 1600 pixels) on an external display

One of the expected upgrades was, as can be expected, with the processor architecture.
With the inclusion of the i5 and i7 processors in the Macbook Pro line, it was to be expected that this processor line would make it over to the iMac. The base model is now available with one of these choices:

  • 3.06GHz Intel Core i3 processor with 4MB level 3 cache; supports Hyper-Threading
  • 3.2GHz Intel Core i3 processor with 4MB level 3 cache; supports Hyper-Threading and Turbo Boost
  • 3.6GHz Intel Core i5 processor with 4MB level 3 cache; supports Hyper-Threading and Turbo Boost


The 27 inch model is now available with one of these choices:

  • 3.2GHz Intel Core i3 processor with 4MB level 3 cache; supports Hyper-Threading and Turbo Boost
  • 3.6GHz Intel Core i5 processor with 4MB level 3 cache; supports Hyper-Threading and Turbo Boost
  • 2.8GHz Quad-Core Intel Core i5 processor with 8MB level 3 cache; supports Turbo Boost
  • 2.93GHz Quad-Core Intel Core i7 processor with 8MB level 3 cache; supports Hyper-Threading and Turbo Boost
Along with the improved processor choices, Apple has also updated RAM capacities, with all iMac now coming with a minimum of 4GB (two 2GB SO-DIMMs) of 1333MHz DDR3 SDRAM; although all machines feature four SO-DIMM slots to support up to a maximum of 16GB of RAM.

All models retain a Firewire 800 port, as well as 4 USB 2.0 ports and as with all new Apple computers:



All models have also gained an SDXC port to conveniently provide access to SD cards without the need for a separate card reader.


All in all, a well balanced set of updates. I look forward to my next trip to the Apple store to get some hands on experience with these new machines.
