Good speed. Compared to the Intel i7-6700K, it is about as fast for office tasks, and 7z compression.
When starting a program, e.g. Word or Chrome - is the same boot time of about 1 second on my system. Some programs sometimes start 0.5 seconds slower, but then I used 500MB / s SSD SATA on Ryzen and NVME 2000MB / s on Intel.
4GB-2133 RAM and 8GB-3200 RAM provide approximately the same speed for such use. You notice the difference only on slightly heavier tasks like 7z, where with RAM / Dual Channel and 3200Mhz can give up to 22% speed difference.
Games I haven't tested.
