The base 21.5″ model has Nvidia GeForce GT 640M graphics with 512 MB of dedicated memory, and the faster 21.5″ model has GT 650M graphics. The smaller iMac has the same 1920 x 1080 pixel resolution as HD TV, and the 27″ beastie provides an impressive 2560 x 1440 pixels. The SD Card slot, which supports SDXC, has unfortunately moved to the back (vs. That’s a quad-core i5 on the standard configurations, and both sizes offer a faster i7 option for those demanding ultimate performance.Īll models now include USB 3 (4 ports), and the 21.5″ 2012 iMac now has two Thunderbolt ports, just like it’s larger sibling. Other DetailsĬPU speeds start at 2.7 GHz, and all Late 2012 iMacs have quad-core processors. Maybe because this is brand new, unproven technology for Apple, there is no Fusion Drive option for the Server version. To revive a phrase Apple has used for a long, long time, it just works. Best of all, this is totally transparent to the end user. The brilliance of Fusion Drive is that the operating system keeps track of your work patterns and will move files, data, and applications to the SSD or back to the hard drive based on that information. It also reserves 4 GB of space on the SSD for use as a hard drive cache.
LATE 2013 IMAC SOFTWARE
Fusion Drive treats the hard drive and SSD as a single 1.125 (or 3.125) TB volume, storing the operating system and all included software on the SSD and initially putting everything else on the hard drive. If you want way more performance, look to the $300 256 GB SSD (768 GB option for 27″ model) or the new $250 1 TB Fusion Drive, which combines a 1 TB hard drive (3 TB option for 27″ iMac) with 128 GB SSD. You can order both the 21.5″ and 27″ models from Apple with 16 GB installed, and there’s even a 32 GB option for the 27″ iMac. If you order your iMac with the base 8 GB of RAM, that’s all you’ll ever have.
LATE 2013 IMAC UPGRADE
That said, you can get a Thunderbolt-to-FireWire adapter if you so desire.Īs with last year’s iMacs, you can’t upgrade memory.
LATE 2013 IMAC MAC
Longtime Mac users may be disappointed that, like the Late 2012 version, the Late 2013 iMacs also have no built-in FireWire port. Another step forward is the use of two microphones, as in the Late 2013 MacBook Air, to improve noise reduction. The Late 2013 iMac follows the Late 2013 MacBook Air as the second Mac to ship with 802.11ac WiFi. And for those wanting an SSD or Fusion Drive, the good news is that these are now connected via a PCI Express interface, which outperforms the SATA Revision 3 used for hard drives. The 21.5″ iMac ships with a 1 TB 5400 rpm hard drive, and the 27″ model bumps that to a faster 7200 rpm drive.
LATE 2013 IMAC PRO
Ars Technica reports that the Iris Pro 5200 GPU offers slightly better performance than the GeForce GT 640M GPU found in last year’s entry-level iMac. By integrating this high-speed memory, processes are not slowed nearly as much as when accessing system memory, although we should note that the GPU does use system memory to drive the entry-level 21.5″ iMac’s display. One advantage the Iris Pro graphics has over Intel HD 5000 graphics is that 128 MB of eDRAM memory is integrated into the CPU, which can be used by both the CPU and the GPU. The big difference this year is using Haswell CPUs instead of the older Ivy Bridge, which should reduce power consumption and heat buildup.Īpple included improved graphics with all but the entry-level 21.5″ model, which settles for integrated Intel Iris Pro 5200 graphics while the rest of the line has nVidia GeForce 700M-series graphics processors. That puts the new low-end 27″ iMac at the same speed as the faster 2012 iMac it replaces. CPU speeds on the 21.5″ models are the same as in last year’s iMacs, but the 27″ model gets a boost to 3.2 and 3.4 GHz.
