More benchmarks (applications and games) are available in our Tech section.Įxpensive optional upgrades are often not worth it in laptops, especially in slim devices. The Vega 20 is sometimes on par with the Quadro P3200, and sometimes it is only comparable to a Quadro P1000 or even P620.

If we compare the scores for professional workloads, the performance depends heavily on the individual applications or sub tests, respectively. The Radeon Pro 5500M in the new Apple MacBook Pro 16 on the other hand is another 20-30% faster. The GPU performance is also stable under sustained workloads (see The Witcher 3 loop and 3DMark Time Spy stress test), so this is definitely a recommendable upgrade. There is a significant advantage over the default Radeon Pro 560X, because the Vega 20 is ~60% faster. The Vega 20 is about 15-20% faster than the smaller Vega 16 in the synthetic 3DMark benchmarks and roughly on par with the Nvidia GeForce GTX 1650. We have already shown that in the previous review. Just like the Vega 16, the Vega 20 also uses the newer GCN5 architecture compared to the other Radeon Pro GPUs (GCN4 architecture), which improves the efficiency.
We are already familiar with the AMD Radeon Pro Vega 20 GPU from our review of the 2018 MacBook Pro 15, back then in combination with Intel's 6-core Core i9 CPU. The new MacBook Pro 16 with the "smaller" and less expensive Core i9-9880H is also almost 10% faster.

We are still far away from the full performance of the 9980HK anyway our average score (from our own reviews) for this processor is 23% higher. Most private users should be more than happy with the default 6-core CPU, and the i9-9880H is the most sensible choice if you really want an 8-core chip. However, the advantage is small and the additional price for the HK processor is not really worth it. HK CPUs are most likely specifically selected chips that can handle the high clocks, so the processor should be a bit more efficient (slightly higher clock at the same TDP) compared to the recently reviewed MBP 15 with the Core i9-9880H, for example. After that, the consumption levels off at around 57 Watts for a short time and then drops to ~52 Watts. Note, however, that the 85W adapter will not charge a MacBook any faster than the 60W adapter.Our observations are basically identical to the other versions of the MacBook Pro 15: We can see a power consumption of up to 100 Watts when the load starts, but this obviously results in high chip temperatures very quickly. Though larger, the 85W unit does not (in some cases) get as hot as the 60W adapter, and might not generate some of the buzzing noises associated with the 60W unit. Incidentally, some MacBook owners have found that they prefer 85W MacBook Pro adapters to the standard 60W adapters included with their systems. If the MacBook Pro is sleeping or powered off, the 60W adapter will increase the available charge. In other words, while the 60W adapter will generally allow you to operate the MacBook Pro without draining the battery, it may not also increase the available the charge. However, the lower-power unit may not deliver enough power to MacBook Pros to offer simultaneous charging and operation. The 60W adapter can also be used to some extent with both the MacBook Pro and MacBook. It will provide ample power to both the MacBook Pro and MacBook, and will not damage the latter despite a higher-than-necessary wattage. The 85W adapter can be used inconsequentially with both models. So are the two adapters interchangeable? Yes, with a caveat.
Both adapters use the same MagSafe connection point that will fit either model. A product specialist at Apple commented that although the packaging indicates use for the MacBook, the power supply would charge a MacBook slower and didn't recommend extended use."īy default, the MacBook Pro uses an 85W power adapter, while the MacBook uses a 60W power adapter. Their information didn't specify whether it was OK to use it or not OK to use it. I called Apple for a more definitive answer, but was unable to get one. The Apple store employee thought it was a bad idea to use the 85W with the MacBook, as the MacBook comes with a 60w adapter, even though Apple's packaging for the adapter indicated it was also for use with a MacBook. (I have a MacBook Pro and thought it would be good to have an adapter that we could both use). The packaging indicates that it is for use only with a MacBook Pro or MacBook. "I bought an extra 85W MagSafe Power adapter for my wife's MacBook. de Sequera recently inquired about the interchangability of MacBook and MacBook Pro power adapters.
