I have recently built my first Ryzen desktop. I am running the Ryzen 5 2600 processor with 32GB RAM, the Sapphire Radeon Pulse RX 580 8GB graphics card, and a couple of SSDs.
My goal was to get system which could handle the output of one 4K monitor and an HD second monitor without any sluggishness. The graphics card seems to be meeting this goal. The 32GB RAM also helps keep the machine spiffy.
What I am finding, though, is that at times when choosing functionality within a website, operations for that activity pauses for a moment or two. Simple actions such as opening a page from a bookmark or pulling a list for a dropbox are met with the same pause. It's more than data retrieval on the backend. The all browser interaction is suspended.
I do see a spike for the browser process in my system monitor, but I've seen that on Intel processors running under the same or lesser load with no latency. The spike happens, but there is no lag with Intel. And the Intel boxes do not have the graphics horsepower or increased memory this Ryzen box has.
And it is not just a single browser. I have seen this behavior with four different browsers on the same system. Is this just a Ryzen thing?
If it is the Ryzen chip, maybe the Ryzen 5 2600X might perform better. Overall, I am pleased with Ryzen and would like to do more with it. This is the only real issue I have encountered.
