Apple's shiny new 15in MacBook Pro 2018 with the powerful 6-core 2.9GHz Intel Core i9 processor – and probably one of the priciest laptops – is running slower than the model released last year, according to one benchmark.
Though Apple claims it's 70% faster than the previous generation, enabling up to 4.8GHz Turbo Boost speed, the 2018 can not keep up because it's the heaviest throttling the processor.
YouTube reviewer Dave Lee uploaded a video that shows a 2018 MacBook Core i9 edition slowing down as the device gets hot very quickly. He added that the throttling began a few seconds after he started to edit the videos on Adobe Premiere.
Lee reveals that the throttling slowed down the Core i9 processor to 2.2GHz though it's being touted as 2.9GHz. On the other hand, the 2017 model with the Core i7 had a 3.1 GHz with the Turbo Boost feature. This resulted in the 2018 MacBook Pro taking 39 minutes and 37 seconds to complete a 5K Premiere Pro render while the 2017 model only took 35 minutes and 22 seconds.
When Lee stuck the 2018 model in a freezer, it performed faster in the colder environment and the rendering time was shortened to 27 minutes. Thermal throttling is not uncommon – companies tend to slowdown the processor when it starts to heat up in order to prevent it from being damaged permanently.
However, in this case, it seems like Apple was unable to equip the 2018 with a proper cooling system and had to resort to extreme throttling. But it's still too early to come to a conclusion, as it's only one benchmark.
Users need to for out of an additional RM1,299 if they choose the processor, which brings the total price of the 15in MacBook Pro 2018 with a standard configuration to RM12,898.
