At first glance, they have not changed in comparison iMac 4K 2017. At least one external difference between the 21.5-inch iMac’AMI 2017 and 2019 is not a trivial task.About the cheapest representative of the iMac, I will not tell. iMac with screen sizes of 21.5 inches with a resolution of 1920×1080 pixels (no Retina), which in the U.S. online Apple store is 1 099 USD, were presented in 2017, and since then have not changed. It is possible to read here. Among other things, it has nothing to do with 4K iMac and is therefore beyond the scope of today’s topic.

At the 4K iMac was flawed. Not necessarily important to those who use them. For example, the design (almost the same as in 2012). Seven years in the computer world several times everything has changed radically, iMac – no. Thick black frame around the screen, connectors on the back side of the screen, beyond simple, durable and devoid of any degrees of freedom stand. And yet – the hard drives, but still not the fastest. In 2019 this throwback. Why not include in the base configuration of your computer, SSD?

Most of those who buy the iMac are two basic requirements: capacity needs to be large (from Terabytes and above), and the price of the computer should not be high (agree? Please share your opinion in our Telegram chat). Not all buyers are the same, there are those who need at least 256 GB SSD – but they are in the minority. RAM in the base configuration, only 8 GB. But the cost of the basic configurations with these parameters fit in the specified in the technical specification limits. Else at the request of buyer and for an additional (often excessive) fee. Besides, with what my friends bought a 4K iMac with 8 Gigabytes of RAM and hard drive capacity of 1 Terabyte it can handle. Without taxes and fees is 1 $ 299. Tolerable?

IMac 2019

In iMac 4K 2019 is used three versions of the Coffee Lake processors and graphics processors of two types. The CPU is not soldered into the motherboard, they are installed in the LGA 1151 socket (but accurate information about successful upgrades of the processor “manually” I do not have):

  • 4-core Intel Core i3 3.6 GHz (i3-8100), cache third level 6 MB, Turbo Boost is not supported.
  • 6-core Intel Core i5 3.0 GHz (i5-8500), cache third level, 9 MB, Turbo Boost to 4.1 GHz;
  • 6-core Intel Core i7 3.2 GHz (i7-8700), cache in the third level 12 MB, Turbo Boost 4.6 GHz.

Graphics processor upgrade is not possible:

  • AMD Radeon 555X Pro with 2GB GDDR5;
  • AMD Radeon 560X Pro with 4 gigs of GDDR5.

Common to all configurations

802.11 a/b/g/n/ac, Bluetooth 4.2. Connectors: a conventional connector for power connection, Ethernet 10/100/1000Base-T(!), card slot, SDXC SD card, 2 USB port-C (Thunderbolt 3), 4 USB 3.0 ports, analog audio and more. The composition of both configurations comes with 8 GB of RAM, maximum size is 32 GB. The memory can be changed after the purchase of the computer, but a normal person to get to the slots for its installation (which you need to completely disassemble the computer) and return it to working condition (which it should collect) is almost impossible. The RAM in different configurations, its types below. For connecting CPU with the chipset used DMI3, with a capacity of 8 Gigatransfer per second.

Screen with a diagonal size of 21.5 inches (54.6 cm), with a resolution of 4096х2304, IPS and DCI-P3, simultaneously with the built-in iMac screen 4K support either a single external 5K display (5120×2880, 60Hz) or two external 4K UHD display (3840×2160, 60 Hz), or two 4K display (4096х2304, 60 Hz).

The delivery composition of all configurations by default, includes a compact keyboard Magic Keyboard and Magic mouse 2. For $ 30 a compact “magic” keyboard can be replaced by its expanded version with the numeric keypad, for $ 50 you can swap the Magic Mouse for the Magic Trackpad 2 2, for $ 129 you can buy a Magic Mouse and Magic Trackpad 2 2.

Initial configuration and options Configurator

In the online store two primary configurations for 1 $ 299 Intel Core i3 3.6 GHz (i3-8100) and 1 $ 499 Intel Core i5 3.0 GHz (i5-8500).

Ports iMac 2019

In the Configurator initial configuration for 1 $ 299 processor can be replaced on an Intel Core i7 3.2 GHz (i7-8700), it will cost $ 300. Type of RAM – PC4-19200 (2 400 MHz) DDR4. For the upgrade RAM to 16 and 32 GB you need to pay extra 200 and $ 600. Independent upgrade possible, but in unskilled hands is the same as that just to break the computer means at hand. Graphics processor – AMD Radeon Pro 555X. Hard drive capacity of 1 Terabyte (5 400 rpm), the connector to connect the SSD when the SSD is not installed at the time of purchase, NOT install. Instead of just the hard drive, you can select in the Configurator Fusion Drive (32 GB SSD + 1 TB HDD), for $ 100, or SSD volume of 256 or 512 GB for 200 or $ 400. SSD 1 Terabyte, from July 9, 2019 will cost $ 600 (before this date – 800).

In the initial configuration for 1 $ 499 replacement processor for Intel Core i7 3.2 GHz (i7-8700) will cost $ 200. Type of RAM – PC4-21300 (2 666 MHz) DDR4. For the upgrade RAM to 16 and 32 GB you need to pay extra 200 and $ 600. Graphics processor – AMD Radeon Pro 560X. Fusion Drive (32 GB SSD + 1 Terabyte HDD 5 400 rpm), you can instead choose or SSD volume of 256 or 512 Gigabytes, 100 or 300 USD or SSD to 1 Terabyte, for $ 500. To 9 July 2019 for Terabyte SSD took a Supplement of $ 700. Independent upgrade of storage, in principle, possible, but not less complicated than an upgrade of RAM or CPU.
