Multitasking slowed the reviewed base model
Albert Unbox reported slowdown while playing YouTube, recording the screen and downloading software together. He also demonstrated lag in Photoshop. His unit had 8GB RAM and 256GB storage, so this is not a measured result for the 16GB/512GB configuration.

Short CPU stress test did not report thermal throttling
Britec09 shows CPU-Z stressing the processor and HWiNFO reporting no thermal throttling on the 8GB/256GB review unit. Test duration, ambient temperature and firmware were not fully documented, so this does not establish sustained behavior for every workload.
