With Apple to address its problems with gas issues with a firmware update for the 2018 MacBook Pro, it's time to take a look at the laptop and complement our original benchmark results from our first review.
We're not going to recreate the entire controversy about the new MacBook Pro here. But if you are interested in the history of this issue, there are some articles you can read (listed in order from the discovery of the problem so far).
This bundle of tests is benchmarks that perform tasks that a professional can do. We ran the tests on the 2018 15-inch 2.9GHz Core i9 MacBook Pro before and after the update. We also tested the 201
Adobe Premiere CC 4K Video Rendering
This test involved an Adobe Premiere video project created by the Macworld video frame. (You can watch the video on YouTube.) We exported a video to H.264 format using preset YouTube 2160p 4K and with maximum Render quality enabled. When we render the video using Adobe Media Encoder CC, we set Render to only the mercury player's software to isolate the CPU.
Our tests of the new MacBook Pro before the update showed a speed increase of 11 percent compared to last year's model. We were unable to replicate the performance loss that YouTuber Dave Lee experienced during his testing (his video was the one who took the damper problem at the forefront).
After the update, we saw a major improvement over last year's laptop-a 22 percent increase.
Cinebench is a reference that involves a 3D rendering, and the CPU voltage spans the available processor cores. According to Maxon, the scene has around 2,000 objects with over 300,000 polygons and a number of effects.
When using all of the Process Core available on each laptop (six on the MacBook Pro 2018, four on the 2017 model). The updated 2018 MacBook Pro shows a 25 percent boost over the 2017 MacBook Pro. Without the update, 2018 MacBook Pro had an increase of 17 percent compared to last year's model.
Cinebench lets you specify how many threads you want to test with, so we ran a series of benchmarks starting with a single thread, then two, four, eight, ten and twelve threads. (Since the MacBook Pro 2017 is a quad-core machine, it can only go up to eight threads.)
Blender BMW CPU
Blender is a free open source 3D program. We used the CPU test on Blender BMW Benchmark to test another 3D rendering. The updated 2018 model was 19 percent faster than the 2017 MacBook Pro. Before the update, the 2018 model became 12 percent faster.
An additional 3D rendering test: V-ray. We used the test designed for the CPU. The updated 2018 MacBook Pro was 19 percent faster than last year's model. Without updating, the new laptop was 12 percent faster.
An Eye of Gas Damage
Through testing, we used the Intel Power Gadget to monitor the power consumption and clock speed of the MacBook Pro CPU. The app shows progress as a line diagram.
Before the update, the 2018 MacBook Pro showed a lot of gas in these tests, and the charts in Power Gadget sometimes resemble countless writers. The CPU clock rate is often dipped down to 2 GHz, and as high as 4.8 GHz, the portable Turbo Burst speed. The temperature and power consumption also showed a lot of variance.
MacOS High Sierra 10.13.6 Additional update had a calming effect on the CPU. Once installed, we saw more flatline results in Power Gadget, with CPU better able to maintain power consumption, temperature and base clock speed.
(Interestingly, Power Gadget was upgraded from version 3.5.2 to 3.5.3 throughout the MacBook Pro controversy and was not available for download for a while when the upgrade was done. It scattered speculations on many websites such as it was intentionally removed to prevent people from monitoring MacBook Pro performance.)
Install the update
If you are planning to purchase or purchase a 2018 MacBook Pro with a touch bar, make sure you install MacOS High Sierra 10.13.6 additional update. (13-inch models without the touch line did not receive updates from the processor and were not affected by this error.) It gives a big difference in performance, especially for multiple core tasks. And it will help the MacBook Pro to run more consistently.
