In spite of that, the 15-inch MacBook Pro model 2017 have earned the title of Pro. Everything was against: and dubious innovations that needed to get used but the benefit of which was not obvious, and manic refinement of the housing and economic situation in major markets.
The presentation about “new” and “outstanding” MacBook Pro said a lot of excess. He was not much more productive than its predecessor. He was faster, but that is to be detected, required “armed eye”. On Autonomous power sources (batteries) of the promised 10 hours, he could not stand. Under a moderate load for 8 hours, a maximum of 9. When using the integrated graphics. Discrete graphics killed it much faster. If even for a couple of hours. A big load has drained the battery for 6 hours.
He basked, forcing to remember about the first MacBook Air. For ten years processors have become smarter and more careful, and heat they react the only safe way. They “reset the momentum.” In zhivoderskie tests naprogesic mobile(!) processor MBP series heavy tasks, he could not stand and took a break, reducing the clock frequency. Is that bad? In real life, these tasks occur. In reality, the chip usually has time to take a breath, and restoring power, return to normal frequency.
No matter how Pro was not a modern laptop for heavy commercial work is much better suited to stationary system. Especially in our time, when a modern laptop is something ephemeral and airy in a very sophisticated (in all senses) body. Before the most powerful representatives of this breed not afraid of work not inferior to desktop computers – but then someone (who?) invented the “laptop of the future.”
A maximum of 16 Gigabytes of RAM
The amount of RAM in the MacBook Pro was limited to an insurmountable limit of 16 Gigabytes, as in 2016, said Phil Schiller. RAM larger, according to him, would consume an unacceptably large amount of energy. Brevity not the soul of wit, is a sister of schizophrenia. Did not understand him, and even ridiculed. In fact, everything about it was, if Phil had called for the real perpetrators of this outrage, Apple no one would suspect the loss of basic skills. But to call them he could not.
If you have forgotten, let me remind you: the Intel processors of the sixth and seventh generation supported two types of memory – DDR4 and LPDDR3. Contacting Intel you can get these processors working with DDR3 and DDR3L. “Call – and we will help”. DDR4 memory consumes significantly more energy than LPDDR3 (the LP is “Low Power” or reduced energy consumption), and the controller for it would require radical processing internal space of the MacBook Pro, which would reduce the physical size of the battery that would reduce its capacity.
Of the two evils in the Apple chose the least: LPDDR3 limited the size of RAM 16 Gigabytes, it was bad, but the(voracious memory and a smaller battery) were totally unacceptable. LPDDR4 nor Skylake or Kaby Lake for some reason was not supported. Another type of memory with reduced power consumption, DDR4L, still being developed. Apparently, Intel had serious reasons for this. In Cannon Lake, 10 nm generation of Intel processors that have been released but whose release was postponed several times, support for LPDDR4 promised.
If the thickness of the MacBook Pro increased by five millimeters would be significantly more capacious (and heavy, alas) battery, and you used DDR4, would be better. 16 GB RAM for notebook Pro class in 2017 is the minimum at which a laptop could fulfill their destiny.
CPU and GPU
15-inch MacBook Pro 2017, there were three modifications of the 4-core Kaby Lake:
— Intel Core i7 2.8 GHz (i7-7700HQ) cache third level 6 MB, with a maximum clock frequency mode Turbo Boost 2.0 to 3.8 GHz;
— Intel Core i7 2.9 GHz (i7-7820HQ) cache of the third level of 8 MB, with a maximum clock frequency mode Turbo Boost 2.0 3.9 GHz;
— Intel Core i7 3.1 GHz (i7-7920HQ) cache of the third level of 8 MB, with a maximum clock frequency mode Turbo Boost 2.0 to 4.1 GHz.
Intel promised a 20 percent increase in productivity, but in reality, it was more modest. Integrated graphics in these processors – Intel HD Graphics 630. MacBook Pro used IHG 630 for tasks with moderate graphics needs. IHG 630 reserved for their needs “to 1.5 Gigabytes total RAM”, actually it was his minimum. The lack of appetite he did not suffer, but gets the job done well.
For tasks with high requirements used a powerful discrete GPU from AMD. Switching between discrete and integrated processors was automatic, and the rules of these shifts was, to put it mildly, not the most optimal. To interfere in this process was impossible, but the switch can be removedIt was called “to Cancel economy mode”. In wasteful mode selectable CPU was working all the time and eat battery power, according to eyewitnesses, an hour and a half or two.
I have never seen this mode used, working from the battery. Even if it were enabled, when you switch to standby power (when you turn off power or disconnect if from the charger) operating system turned that off. It was configured by default.
15-inch MacBook Pro 2017 used two versions of the discrete GPU:
— AMD Radeon Pro 555, with a 2 GB GDDR5;
— AMD Radeon 560 Pro with 4 gigs of GDDR5.
Configuration and specifications
The initial configurations of the 15-inch MacBook Pro in online Apple store had two, with Intel Core i7 2.8 GHz (i7-7700HQ) + AMD Radeon Pro 555, 2 $ 399 and Intel Core i7 2.9 GHz (i7-7820HQ) + AMD Radeon Pro 560 2 799. Each of them in the Configurator had the option of replacing the processor Intel Core i7 3.1 GHz (i7-7920HQ), for a fee of $ 200.
Itavalta the CPU into the motherboard.
RAM in both configurations, 16 GB PC3-17000 (2 133 MHz) LPDDR3 SDRAM. Some sources claim that it is not LPDDR3 and LPDDR3E, “advanced option” LPDDR3 large clock frequencies. To change the size of RAM was absolutely impossible even in the Configurator. RAM was vpisalas into the motherboard.
In the configuration 2 for $ 399 included a SSD volume of 256 GB, which for 2017 in the professional notebook was ridiculous and unacceptable, fortunately in the Configurator is easily corrected, for an additional fee. You can choose SSD 512 GB, 1 TB or 2 for 200, 600 and $ 1,400. Then flash memory has vpisalas into the motherboard and to change it is impossible.
In configuration 2 799 consisted almost decent amount of SSD of 512 GB, is it in the Configurator you can choose SSD capacity 1 or 2 TB for $ 400 or 1 200 dollars. All this was vaivaros.
Connectors was five. Audio output (analog) audio Jack, USB and 4-C (Thunderbolt 3), two on the left and right sides. In 2016, it shocked and it was a sensation in 2017 are already accustomed to –still grumbling about it. In the rest of the 15-inch MacBook Pro 2017 was one-to-one similar to that of its ancestor of 2016.
