Last week, Apple presented improved iMac. It received a major upgrade to 21.5-inch model. Now it comes with a 4K-screen TV. Potential buyers the question arises: what to choose? Relatively compact model or larger, and feature-rich? edition iMore was guide to buying, and we have adapted it and added to the actual information Russia.
displays
21.5-inch iMac now comes with 4K Retina-screen with a resolution of 4096 × 2304 pixels, which gives a pixel density of 221 dots per inch. This higher standard 4K-resolution 3840 × 2160.
27-inch iMac has a display with a resolution of 5120 × 2880 pixels and a density of 218 dpi.
According to the density of dots per inch matrix technology employed (IPS LCD) and reverse illumination (LED) displays are equivalent. The displays differ only diagonal and resolution.
processors
21.5-inch iMac 4K comes with a 4-core processor Intel Core i5 generation Broadwell, working on 3.1 GHz, but it can be replaced by a quad-core Core i7 generation skylake, clocked at 3.3 GHz.
27-inch iMac is available only with Intel processors generation Skylake - a quad Intel Core i5 3.2 GHz. You can buy a version with a more powerful Intel Core i7 with a frequency of 4 GHz.
Generation Broadwell and Skylake different energy efficiency. However, for a desktop computer that is connected to a power outlet, it is not critical. On the other hand, Intel Core i7 generation Skylake with a frequency of 4 GHz - performance solution, and there are buyers who know how to use this power to the maximum.
Graphic arts
Here, everything is much clearer. 21.5-inch iMac uses graphics solution Intel Iris Pro 6200, iMac 27 "- chips AMD Radeon R9 M380, M390 and the M395X. This graphic system is fundamentally different level, designed to work with video editing-and 3D-modeling. However, Intel Iris Pro 6200 will be enough for photo editing and video editing simple, so proceed from their own needs.
RAM
Both models come with 8 GB of RAM LPDDR 3, and the difference - the maximum extent possible. In the case of 21.5-inch model upper limit is limited to 16 GB, a 27-inch can be purchased with 32 GB of RAM. Now 8 GB - this is the optimal amount for most users, but professionals working with graphics and video editing, it is worth considering at least about 16 GB of RAM, because the program for video processing rather "Voracious".
Data storage
The 21.5-inch model is installed by default on the hard disk 1 TB with a spindle speed of 5400 revolutions per minute, which by today's standards is not enough. But for the extra money, you can expand storage up to 2 TB Fusion Drive or SSD to 512GB.
In the 27-inch model in younger configuration has a disk 1 with TB spindle rotation speed 7200 rpm. In the middle configuration - Fusion Drive 1 TB in high - Fusion Drive 2 TB. In all three configurations, you can set the Fusion Drive or up to 3 TB SSD up to 512 GB.
Price
In Russia, the official price of 21.5-inch iMac with the Retina screen, begin with 123 thousand rubles. For the money you get a slow hard drive, graphics semiprofessional level, 8 GB of RAM and Intel i5 processor of the previous generation. It is obvious that such a computer is suitable or regular users who buy a computer for home use, or professionals who for work tasks do not need top-end filling. If the task requires more, the processor, memory and data storage can upgrade, but the schedule - not. It is worth bearing in mind.
27-inch iMac 5K stands in Russia from 150 thousand rubles for a younger model. It installed the latest generation Intel i5 processor, hard drive optimal speed and good graphics solution AMD R9 M380. This schedule may have come for serious video editing and simulation, but memory and data storage for applications such desirable upgrade. However, even older model of the iMac 27-inch, which costs 190 thousand rubles, comes with 8 GB of RAM, which is strange.
results
The new iMac have turned out interesting, but ambiguous computers. On the other hand, Apple tried to meet the demand for both general users and professionals (especially the 27-inch model). In any case, proceed from their needs and financial capabilities and match the configuration wisely.
