24 Sep 2013 the online shop was closed “for stocktaking” to update something on its shelves. It happened on Tuesday when Steve. In the era of Tim cook’s online store was updated on Wednesdays. Why not just suggested thirsty, while the store was unavailable. It turned out, refreshed the iMac lineup…
When the virtual doors of an online store hospitably opened, the crowd of curious with a sinking heart, went to read about the iMac with Retina display. The online stores have many benefits over conventional, but the most important of them – this can crowd almost half of the “Apple” world, which in 2013 belonged to more than 70 million Homo-sapiens (according to Apple, of course), but nobody interferes with anyone.
They were disappointed: the new iMac displays were exactly the same as before. Retina displays, something that was waiting for like waiting for New year celebration or Christmas (depending on personal depravity), that day has not happened. In fact, the screens of the iMac, the 21.5 – and 27-inch, was good without it, but the masses sometimes possess more strange ideas.
The update would be the usual speed bump, or renewal nothing is improving in addition to performance, if this is the performance improvement was not so modest.
The new lineup compared to the previous one (it was easy, both series consisted of 6 options, 3 with a diagonal of 21.5” and 27”, and of these three two were “initial configurations”, and one option was the result of the replacement of the processor greater).
Worst of all the acceleration happened to configurations with more powerful processor (productivity growth of 1.5% and 6%), maximum acceleration does not exceed 16%.
The graphics performance on Apple’s claims, increased by 40 percent.
As you already understood from the title, below is the tour model with a diagonal of 21.5 inch, and this time it is really model, with different IDs…
Intel Core fourth generation (Haswell)
iMac 2013 surpassed last year’s, but very slightly. Notice the acceleration in the 16 percent to the naked eye is impossible, especially since the real life is markedly different from the tests that I put the computer in an uncomfortable position for him, their goal to expose him and his creators mistakes and shortcomings.
iMac 2013 was quite productive, even for rather difficult task (there were many designers of user interfaces, and developers), especially if the inside was either pure SSD or Fusion Drive. Option hard disk drive (with a rotating speed of 5400 rpm, an ancient laptop) I haven’t tried it – but most likely the impression of the iMac would be spoiled.
Most users have “little” iMac’s 2013 such problems never arose, and all of them were more than satisfied.
Recommendations smart expert Mac am was simple and clear: if you have a 2012 iMac, special sense to change it to iMac 2013 no. If the iMac is older or no – buy.
If you remember, the main goals of the project Haswell two: efficiency and graphics. For desktop the first of them is almost irrelevant (in electricity bills will be slightly smaller amounts), the second…
In addition to these goals, Haswell was Packed with innovations like an early beta version of the operating system bugs. Their joint work and provided all of the productivity growth, the contribution of the processor in it was a record low.
Two models, three options
In the online store iMac with a diagonal of 21.5 inches was represented by two initial configurations 1 1 299 and $ 499. In the Configurator a second was the option of replacing the processor in a more productive, for $ 200. Option with this option on Board (1 for $ 699) and has surpassed his counterpart from 2012 only 1.5%.
The initial configuration was applied to two different models: one in which 1 299 used integrated graphics from Intel, but now it was completely different graphics from Intel. The ID of the model with integrated graphics was iMac14,1.
Configuration 1 for $ 499 and its variant with i7, in 1 699, was iMac14,3.
In all configurations of the iMac with a diagonal of 21.5 inches (55.6 cm) between the processor and chipset, there was neither bus nor DMI – they were connected “directly” through OnPackage Interface (OPI). The benefit of this was that DMI was called “brake” – but more recently things were different.
The type of RAM in all iMac with a 56-cm diagonal was the same, and exactly the same as his counterparts from 2012. PC3-12800 (1,600 MHz) DDR3 SDRAM. The two initial configurations consisted of 8 Gigabytes of memory in the online store, its size can be increased to 16 Gigabytes ($200).
Apple wanted to convince the customers, the finality selected during the order of the size of installed RAM – and most of the buyers believed in the descent of good fire. Actually RAM into the motherboard did not waives, and its size could be increase – that’s just to get to the RAM slots was not easy, for this it was necessary to disassemble almost the entire iMac, slots located in close proximity to the rear wall of the computer.
Remove the thin and fragile composition of glass screen protective LCD cover, and thoroughly affixed to the body, then, risking every step of the way to damage any vital transactions or the connector, removing motherboard. Slots in front of you, this part of the upgrade is the simplest. And with the same care and discretion, only in reverse order, to return to the place.
The set of connectors is exactly the same as last year’s model. And Thunderbolt in iMac 2013 first. Why? You have the monopoly owner of the rights to Thunderbolt, Intel, the price chip support Thunderbolt 2 was such that Apple was the choice of one of two evils: either use Thunderbolt 2 and raise the price of a new iMac, either to save costs and not bother. I chose the latter. In their place you would do the same.
But “the biggest iPhone” the company has expanded its wireless ability, through support for 802.11 ac.
In all variants iMac with a diagonal of 21.5 inches (55.6 cm) was used the same discs with the same options and disadvantages.
The two configurations included hard drive 1 TB (5 400 rpm). Options in the Configurator are the same for all 21.5-inch models for $ 200 it was possible or to turn the drive in the Fusion Drive (adding a SSD volume of 128 GB), or replace hard disk to SSD volume of 256 GB.
For $ 500 hard drive was replaced by SSD of 512 GB.
Apple announced about the impossibility of replacing the drive at home – but one who was able to get to the RAM slots could do with the drive whatever they want. On one condition: if in the Configurator the online store was chosen as one of the options including SSD. In these cases, Apple has installed a dual interface to connect the drives, consisting of a SATA III (6GB/s) hard drives based on PCIe SSD.
In iMac whose configuration delivery included only the hard drive, the PCIe interface is not installed. How can they do this to us?
In the initial configuration for 1 $ 299 used 4-core Intel Core i5 2.7 GHz (i5-4570R) cache of the third level 4 MB, is able to increase the clock speed in Turbo mode up to 3.2 GHz.
The option of replacing the processor for iMac14,1 is not provided, the processor in all 21.5-inch models itavalta tightly into the motherboard. Including in iMac14,3 (initial configuration 1 for $ 499).
In configuration 1 for $ 499 was part of a 4-core Intel Core i5 2.9 GHz (i5-4570S), cache third level 6 MB, and dynamic frequency in the turbo mode of 3.6 GHz. For $ 200 it can be replaced by a 4-core Intel Core i7 3.1 GHz (i7-4770), cache in the third level of 8 MB and a turbo frequency of 3.9 GHz.
The main difference between iMac14,1 or iMac14,3 were type of graphics. The first used the integrated Intel graphics Iris Pro 5200, reserving for their needs 1.5 Gigabytes of shared memory.
Intel Iris Pro 5200 to compete with discrete graphics in huge size segment of cheap graphics processors.
In iMac14,3 used discrete graphics based on the NVIDIA GeForce GT 750M with its own Gigabyte of GDDR5.
