iMac 2013 review, specs: The 21.5-edition of the iMac is the all-in-one for the masses and sports the aesthetic design that has made Apple as the purveyor of high-speed and good-looking desktops. But a review below by Arsetechnica highlights the flaws of the desktop, which most users can forgive unless they have more workload to do. In that case, they might opt for the 27-inch Apple iMac or the upcoming MacPro.

Despite the optimism, a review by Arsetechnica remarked that Intel’s Haswell architecture increases performance relative to Ivy Bridge running at the same clock speed. However, the upgrade of the iMacs with the new processor is more concentrated on battery life improvements than performance improvements. Arsetechnica said that the benefit of the Haswell for desktop users are less readily evident.

TechRadar noted that there’s no doubt the new Intel integrated graphics are far more powerful than the HD Graphics 4000 built into the Ivy Bridge processors and the lack of a discrete GPU will not hold a Mac user from surfing, emailing and word processing. TechRadar recommends that for users with graphics-intensive applications, the higher-end iMacs is worth the extra bucks.

When TechRadar compared the entry-level 2013 21.5-inch iMac with its mid-201 version, it reveals the immense developments Apple’s all-in-one computer has received. The new iMac’s Xbench score is over 31% higher and the Cinebench score, when using multiple cores is almost 102% improved. In a test, the new iMac encoded a five-minute test video into iPod format a minute quicker.

The newer iMac was slower in ripping a new CD during the TechRadar test, but they noted that it’s only because they had to use an external USB SuperDrive, since the new Macs has no more optical drive.

Audio quality for the new iMac took a quality upturn in the new 2013 version, a key spec that has been improving each and every year.

The bottomline: The new iMac has definitely received some improvement over the years and the Haswell is a performance upgrade over an Ivy Bridge or Sandy Bridge CPU. However, for key most tasks, the user will not really notice the uptick in speed.
