Or it might not be true, but MPG does not have that other model to test.Īccordingly, all benchmarks with the 2016 MacBook Pro are dubious the performance in sporadic use may be significantly faster and in sustained use, significantly slower. #2016 MACBOOK PRO STANDS UPGRADE#It is worthwhile to ask whether the CPU speed upgrade may be a waste of money for those whose work involves sustained loads it might be that the slower 2.7 GHz CPU runs just as fast under load, since both might degrade to some level that keeps heat dissipation at a steady state level. But with later iterations, the time increases to an average of 4.0 seconds, which is a 23% degradation in performance. Observe that at first, the 2016 MBP runs the test in the 3.2 to 3.3 second range. Decline in performance with sustained usage 2016 MacBook Pro, 2.9 GHzīelow are times for 424 iterations of the Photoshop sharpening test with results for the 2013 MacBook Pro further on. ![]() The results here do not set a general rule, they merely show that a laptop is not a desktop in terms of reliable performance. The 2016 MacBook Pro is very likely to outperform earlier models for some tasks, possibly by a good margin, especially GPU-intensive tasks. NOTE: performance is task specific, not some hard rule. It seems fair to ask: has Apple degraded the 2016 MacBook Pro as a tool that can offer reliable performance? By making it more thin, its ability to shed heat is impaired. #2016 MACBOOK PRO STANDS MAC#No such pattern was seen on the iMac 5K or 2013 Mac Pro.Īs well, there are strange delays at times with the 2016 MacBook Pro that MPG has never experienced with the 2013 MacBook Pro. This dirty little secret is not mention in the “brag sheet” aka specifications. Apparently the GPU cannot handle sustained loads, and must be severely throttled back after at most about 30 seconds. Disabling the GPU results in identical performance when tasks use the CPU instead. #2016 MACBOOK PRO STANDS UPDATE#Update 16 July 2017: it turns out that this is a GPU throttling behavior. For example, with 10 iterations of of the Photoshop sharpening test, the 2016 MacBook Pro declined in performance at later examples. ![]() While testing the 2016 MacBook Pro, a consistent pattern was noticed in that performance declines with each iteration of a test in Photoshop. These bugs were seen only on the two MacBook Pros and not on the iMac 5K and Mac Pro. That would be consistent with the inability to complete some tests in Photoshop due to GPU bugs that caused Photoshop to issue a GPU error dialog (the LensCorrections test could not be completed on the laptops). If so, a fix in a release of macOS is possible. #2016 MACBOOK PRO STANDS DRIVER#Update 07 December 2016: MPG has a hunch that the behavior seen here is a GPU driver bug, perhaps one that leaks memory and thus rapidly degrades performance. Update 09 July 2017: the 2017 MacBook Pro behaves similarly it slows down under sustained load. MPG tested a fully-loaded 2017 MacBook Pro with 1TB SSD. Suggested accessories include the OWC Thunderbolt 3 Dock and 1TB Envoy Pro EX.
