In a bit of a surprise move, Apple unveiled new 13-inch and 15-inch MacBook Pros on Thursday, July 12. The surprising bit is the hush-hush update occurring just over a month after the annual WWDC event, where new products aimed at developers and pro users are usually revealed. This has us wondering why the new 2018 MacBook Pros weren’t part of the WWDC keynote event.

While they didn’t make the keynote, they do pack quite a wallop over earlier models of the MacBook Pro, especially the 15-inch model, which we’ll look at in detail here.

15-inch MacBook Pro (2018)
Before we get too far ahead of ourselves, I want to point out that this isn’t an in-depth review of the 2018 15-inch MacBook Pro. Instead, we’re looking at the specs and how they compare, and what kind of improvements and changes the new MacBook Pro models bring.

First off, the 2018 MacBook Pro isn’t a typical speed bump update. Instead, it brings new features and benefits to those lucky enough to be upgrading at this time. Instead of just dropping in a slightly faster processor, or perhaps a different battery, Apple added a number of new features and capabilities.

Eighth-generation Intel Core i7 and i9 Processors
The 15-inch MacBook Pro leaps from quad-core i7 processors to new six-core i7 and i9 Intel processors in the Coffee Lake family. The Coffee Lake processors have a good deal going for them beyond just two extra cores. Both the i7 and i9 processors support hyper-threading, allowing two threads to run concurrently on each core for a total of 12 active threads. Level 3 caches have also been increased to 9 MB for i7-equipped MacBook Pros, and 12 MB for i9-equipped MacBook Pros.

The increase in level 3 caches should speed up overall performance, especially when instructions or data are being shared between cores.

The Coffee Lake processor equipped MacBook Pros are offered in speeds of:

  • i7: 2.2 GHz with Turbo Boost speed of 4.1 GHz
  • I7: 2.6 GHz with Turbo Boost speed of 4.3 GHz
  • i9: 2.9 GHz processor with Turbo Boost speed of 4.8 GHz

Sharp-eyed readers may notice that the 2017 models of the 15-inch MacBook Pro had slightly faster base processor speeds, clocking in at 2.8 GHz and 2.9 GHz. But the earlier generation i7 Kaby Lake processors had smaller level 3 caches, two fewer cores, and slower memory architecture than what is present in the new Coffee Lake models.

With the processor and memory architecture upgrades in the new 2018 MacBook Pro, Apple claims a 70 percent increase in performance. We haven’t been able to put the new MacBook Pros through any benchmarks, but a quick perusal of the GeekBench Benchmarks shows an i9-equipped 2018 MacBook Pro with a 5289 Single-Core score and a 22201 Multi-Core score. Compared to a 2017 2.9 Ghz i7 model with a Multi-Core score of 15252, that works out to just a bit more than a 68.69 percent improvement, at least in artificial benchmarks. Real-world usage will be quite a bit different, but the performance increases in the benchmarks are impressive.
