The Design
iMac is the thinnest ever among Apple iMacs, although the frontal view of iMac deceptively masks the bulk behind. Look at the image of iMac generations given by Apple:
From the front, it looks like it is as thin as a smartphone, probably the iPhone. The edge of the new iMac is only 5 millimeters thick, making it the thinnest of all high end desktop computers.
The Display
The LED IPS backlight display of iMac produces 75 per cent less reflection according to Apple. This, however, needs to be seen. The reduction in reflection, which used to be one of Apple’s weak points, is a welcome change. Apple has reengineered the display panel to reduce the distance between the antireflective coating and the LCD panel in order to improve the display. This gives the display a printed-on appeal.
The display technology used here is the same as in iPhone 5, and it gives more accurate color reproduction than other technologies like AMOLED.
The Memory
RAM comes at 8 GB standard and you can order up to 32 GB in the 27 inch model and up to 16 GB in the other model. In fact, since this Apple iMac is for the most part of foreseeable future, I recommend purchasing the highest amount of RAM possible.
The Storage
Almost all the storage you need is there in this iMac. 1 TB is the minimum storage available. However, one disappointing aspect of the 21 inch model’s hard disk has the rpm rate of 5400. I recommend any upgrade option to Fusion drive to eliminate issues. The Fusion drive technology is a perfect mix of regular hard drive technology (inexpensive) and Flash drive technology (highly expensive). This makes Fusion drive moderately expensive and better performing than the regular hard disk.
Alternatively, in 27 inch model, you have the option to go for a 768 GB flash storage. It will definitely make your iMac much faster. However, the price will be much higher too. It is an unnecessary option in fact.
The Graphics
NVidia GeForce graphics cards with appropriate amount of memory means you won’t have to worry about gaming and HD video performance. However, I could really use a minimum of 1 GB graphics RAM in all models. It would have been future-proof. In the 27 inch model, you could really go with the 680MX with 2GB option if you are an avid gamer. For regular uses, the other card is more than perfect.
Performance
There are no issues there. In all performance tests done by CNET, iMac performs better than the competition. The third generation Core i5 and Core i7 processors of Intel give you the TurboBoost technology. Have you noticed I have given two speed ratings of processors above? The base speed is the original speed of the processor, and when there is high load, the processor automatically overclocks to give the higher speed given in the table. This is the effect of Intel TurboBoost technology.
Ports and Connectors
Apple’s weak point is the ports and connectors available in the iDevices. iMac has four USB 3 ports, 2 Thunderbolt ports, SDXC card slot, and a GbE port. One thing to be noted in this iMac is the introduction of Thunderbolt. Two slots Thunderbolt, which supposedly can transfer files at speeds of
up to 10 Gbps. If the Apple claim is true, Thunderbolt could prove to be an extremely powerful connector. It can support all kinds of devices—USB, DisplayPort, HDMI, VGA, etc. Probably, this is the reason why Apple doesn’t include HDMI, DVI, or such other ports.
The Gigabit Ethernet port is provided in iMac (based on IEEE 802.3-2008 standard which defines faster Ethernet connections) that will provide better connections via Ethernet cord. This is also a future-proof system.
Another important aspect to be noted is the absence of a DVD drive in iMac. It probably came to Apple’s attention that DVDs and even Blu-ray discs are not the technology of the future. Also, if you need to add one, simply use the Thunderbolt or USB 3 connectors.
In terms of ports and connectors, I don’t see any issues other than the need for adaptors, which basically any iDevice needs, I guess.
The Software
iMac comes with all the basic apps preloaded. And it runs Mountain Lion. This means, you don’t have to worry about purchasing or installing new apps for any basic PC functions. On the other hand, in order to do specific jobs, gaming, blogging, design, etc., you have to purchase apps needed through the Mac App Store itself. There is an app that points to the store in the new iMac.
In Conclusion
For gamers and high end workers, fetch the iMac with the best configuration there is—27 inch, with 3.4 GHz processor, 16 or 32 GB RAM (highly future-proof), 3TB storage (do away with the flash drive option), and 680MX graphics processor. For regular users, the low end model is perfect. If you are going to use the iMac for a long time, a RAM upgrade is highly recommended. Overall, there is no competition to the current iMac in performance and aesthetics. Apple has done an amazing job with it. Review rating:
