MacBook Pro with Core i 9 is criticized as 'CPU's inherent performance can not be drawn out'

By Mashable

In the 2018 model of MacBook Pro announced on July 12, 2018, Intel's 8th generation processor, the 6th core, Core i7 is installed as standard, and it is possible to spec up to the higher performance Core i9 as an option It is possible. YouTuber's Dave Lee who actually purchased the Core i9 model of the MacBook Pro, but when I tried using it, "Because of the problem with the heat exhaust structure of the MacBook Pro, it is not based on the original performance of Core i 9, It is clear that even the clock can not be maintained ".

A review of the MacBook Pro 2018 model that Lee actually published on YouTube can be confirmed in the following movie.

"Because the model with Intel 8th generation CPU of MacBook Pro was announced, I bought it immediately," said Lee, YouTuber. On the left is the Core i 7 equipped model of the MacBook Pro, and the one on the right is the Core i 9 equipped model.

"Although it is obvious that it is high because it is an Apple product, the Core i9 model is very expensive," many people remember hesitating to pay 300 dollars (about 33,000 yen) simply by changing to Core i 9 It is supposed to be.

"If you choose the best configuration up to storage and memory, it will be a tremendous amount of money, but if you keep reasonably standard configuration, price will remain high, but it should be reasonable price "

"Let's take a look at the CPU that changed significantly in the 2018 model.Core i9 is very fast in terms of CPU alone, especially if it is specialized for multithread processing (processing using multicore) We will demonstrate the performance of the monster class. "

"However, the case of the MacBook Pro has the problem that CPU cooling can not catch up at all"

"I tried to check the state of clock frequency by actually rendering with movie editing software Adobe Premere on MacBook Pro. Although the base clock of Core i9 is 2.9 GHz, it is 3.0 (Frequency) base clock We were not able to maintain around GHz, and on the contrary, we can see that the clock frequency rises and falls, and the frequency is not stable at all. "

"Terminals that are able to perform cooling properly like GIGABYTE AERO 15X do not become unstable so far.In fact the waveform of the upper frequency is very stable and the temperature of the lower part is the same as before In the MacBook Pro, the temperature was 91 degrees, but it was 86 degrees for AERO 15X, keeping it at a somewhat lower value "

"That is, the Core i9 model of this MacBook Pro is not well exhausted and as a result, Intel's Core series can not keep even the base clock, not to mention Turbo Boost, which overclocks the clock frequency To be honest, it is impossible as a product. "

"Originally, Core i 9 installed in this enclosure can be overclocked to 4.8 GHz, but with this product it's all in vain."

"It is obvious when you see the actual rendering time as to how much performance is degrading."

The following graph compares the rendering time of the Core i 7 model with the Core i 9 model of MacBook Pro, and the AERO 15 X (with Core i 7). Lee says, "Because Adobe Premere is optimized for Windows, it is unavoidable that AERO 15X will be overwhelmingly faster, so I will skip the explanation.If you compare with only MacBook Pro, MacBook Pro Processing is slower on Core i9-equipped models. "

"By the way I tried out the Core i9 equipped model in the freezer ... ...."

"The rendering time has improved greatly, honestly it is terrible, it can not be ridiculous and defense can not be done"

"I think that such products should not be sold, and in fact many people think that the Core i 9 model is" high performance "and I also buy movies to YouTube Above, you need a terminal with high specifications such as movie editing etc. However, if performance deteriorates so far due to waste heat problem, it is equal to fraud. "

"I will look at the CPU so far and then look at the GPU, the 2018 model of the MacBook Pro is equipped with the Radeon Pro 560X, which is equipped with something more powerful than the 2016 model and the 2017 model I am ... .... "

"It's not a very good performance to play games, you need to install Windows on a MacBook Pro using Bootcamp or connect an external GPU to enjoy the game."

"Next, I will look at the display.The display of the 2018 model of the MacBook Pro adopts True Tone, and it changes to an appropriate and easy-to-see color according to ambient light.In a confusing change There is, but this is a good thing. "

"The keyboard adopts the 3rd generation butterfly keyboard.In personal impressions, it is an impression that the feeling of keystrokes does not change with those of the 1st generation and 2nd generation. Never say that it is a keyboard for everyone I can not tell you, I should get used to it while using it. "

"A thin film made of silicon is affixed under each key, and it seems that the problem problem of the keyboard which had become a problem so far will be improved."

"Memory can be mounted up to 32 GB and power consumption has been slightly increased by becoming DDR 4 "

"To compensate for this, the battery size of the MacBook Pro is slightly larger, so the actual battery drive time is 8 hours, which has not changed from the previous model."

"SSD is very fast, I think that it is the fastest notebook PC currently on sale"

Lee says, "As a general comment, the 2018 model of the MacBook Pro is not" bad. "I like macOS and I love the design of Macbook too, so long as I do not have a waste heat problem, my It will be a favorite. " Also, as being involved in the brand problem, "Since it is sold under the name" MacBook Pro ", not trying to put the latest parts in anything, we have to make it ashamed as a professional specification," Lee It pointed out.
