Apple iMac 21.5-Inch 4K Retina Display-Apple iMac 21.5-inch sold for $ 1,099 (£ 899 or AU $ 1349) and position himself as the MacBook Air basically recast as a desktop system is the new version for 2015 is higher.
Update 2015 21.5-inch iMac is 4K resolution beautiful screen and starts at US $ 1,499 (£ 1,199 or AU $ 2099). Two other basic model, at $ 1,099 and $ 1,299, retain their 1,920x1,080 screen.
The screen resolution is 4096 pixels, instead of the more common consumer version (sometimes called ultra-high definition or UHD), which has only a slightly lower resolution and 3840 pixels wide. Which tells us that the system is targeting fans of photos and videos, which may shoot a higher version than 4K. The 4,096x2,304 on the new iMac screen will play your content 4K fine, although small differences in native resolution may have the effect of small scale, we really only see when looking at 3840 resolution test pattern.
The new Retina display supports a wider color gamut P3 versus the more common sRGB (standard Red / Green / Blue) version. Translated for the rest of us, it means the screen can display more colors than green and red spectrum (blue, the third leg of the triangle of color, is quite maxed out under RGB). Apple says it adds up to 25 percent more colors available for the display.
P3 is the standard for digital cinema projection in cinemas, and to the specific professional photo and film and video experts. For photo enthusiasts, you are unlikely to be able to appreciate the difference, as very few consumer-grade equipment will give you a file that can take advantage of the wide color gamut P3 (some DSLR cameras). But in the familiar chassis convex iMac, there are some important specification changes for 2015.
The three models of 21.5 inches jump from Core i-series processors fourth generation of Intel's new fifth-generation chips. This is important because previous iMac CPU two generations behind. However, only the 27-inch iMac, now all featuring high 5K screen, up to the very latest CPU, the sixth generation of the recent Intel Core chip, sometimes known by the codename Skylake. Also new 21.5-inch iMac is the Thunderbolt 2 ports for faster data transfer (if you have a Thunderbolt equipped accessories) and some new hybrid hard drive option, Apple calls them Fusion drive, combining a small amount of solid state memory for faster access of Data that is frequently used, with a standard large platter drive.
In addition to a higher screen resolution and a new CPU, the biggest apparent changes to the iMac line was revamped collection of accessories bundled with it. Apple Wireless Keyboard, Magic Mouse and Magic Trackpad. Third lose their dependence on disposable batteries, instead of moving to an internal lithium-ion battery that can be recharged. Which allows the keyboard and trackpad for a slim, eliminating the battery compartment bulb which dominated the previous design. Magic Keyboard is smaller and flat, but has a face that is slightly larger keys. Magic Trackpad 2 has a larger surface area and now supports Touch Force, such as bearings in MacBook and MacBook Pro. Magic Mouse 2 looks the same, but the hair is lighter with better rubber tracks along the bottom.
The iMac is dominated by the screen, which also houses all of the system components. This is still only 5mm thick at the edge, gently bent behind. It looks almost as thin as the paper when viewed from the right angle, and still pretty slim even in full profile, in which the panel behind the arc in the center gently into a bowl shape. That the top is connected through a hinge adapted to curved stand. If you do not connect any external USB, Thunderbolt 2, or the Mini DisplayPort, and use Wi-Fi instead of a wired Ethernet connection, this is basically a cable setup with a single white power cable in the bottom center of the rear panel. Like most Apple computers, this is a closed system, with no user-accessible components.

Design and Features
The iMac is dominated by the screen, which also houses all of the system components. This is still only 5mm thick at the edge, gently bent behind. It looks almost as thin as the paper when viewed from the right angle, and still pretty slim even in full profile, in which the panel behind the arc in the center gently into a bowl shape. That the top is connected through a hinge adapted to curved stand. If you do not connect any external USB, Thunderbolt 2, or the Mini DisplayPort, and use Wi-Fi instead of a wired Ethernet connection, this is basically a cable setup with a single white power cable in the bottom center of the rear panel. Like most Apple computers, this is a closed system, with no user-accessible components.
Connection and Performance
In one row behind the casing is a collection of ports and connections, including four USB 3.0 ports, two connections Thunderbolt / mini-DisplayPort, an SD card slot, an Ethernet jack and plug the headphones. The only real difference this year is that the Thunderbolt port Thunderbolt has been increased from the original specifications with newer Thunderbolt 2. Missing is a USB-C, small, reversible pairs found in 12-inch MacBook and some Windows PC. Between this and the new Beats Pill + speakers, it certainly seems as though Apple is betting big on the Lightning as default connector, instead of the USB-C. With the new 4K iMac, you step up from the fourth-generation processor Core i5 and Core i7 Intel's fifth generation.
In the case codename, which went from Haswell to Broadwell. But, it's still a step away from the new chips began to ship in consumer laptops and desktops this fall, the sixth generation of chips Intel Core (yes they also have a codename, Skylake). The real benefit, over the years, has the latest Intel processors, improved power efficiency and battery life is better, which is more important for laptops and hybrid rather than a desktop. In the benchmark test, 4K new iMac with 3.1GHz Intel Core CPU i5-5675R performed on par with most other Core i5 system, shows minimal performance leap between generations of Intel chips in the daily tasks we use for testing. It was about as fast as last year's big 27-inch iMac 5K, although no doubt Skylake powerful new 27-inch models will be faster.
Bringing up the rear is the latest Apple laptop, 12-inch MacBook, running Intel chips are rarely used so-called M core. In the hands-on use, the new iMac feel very excited, even when playing back video files 4K, manipulating large photo files, or jump between multiple browser and multimedia applications. While the 27-inch system offers R9 discrete graphics from AMD, 21-inch models now includes only the default Intel graphics hardware. Higher iMac 21-inch last year include Nvidia GeForce 750M graphics, but it was already well out of date graphics chip last year (the equivalent of GeForce 950 meters) to the main game we recommend at least 960m GPU.
