There is likely some AMD bias, but don't assume pro AMD statements are bias. Many, including me, are neutral. I give Intel a lot of crap currently because they are ignoring perf/watt and chasing power limits through the roof. When they finally do get their ducks in a row, I'll have something nice to say, and will likely build an Intel system again.
I am a senior software developer (I've been doing both software and hardware projects for more than 25 years, but currently mostly focus on software, though I do have an embedded project I am getting into that may require some custom hardware stuff) and I currently prefer AMD over Intel because from a performance standpoint, AMD has the edge (around 10-13% for 7950x vs 13900k) in a lot of my workloads, and from an efficiency standpoint, they outperform Intel by a large margin (7950x system pulls around 350-400w from the wall loaded, add another 70-120w for the Intel system for the same workload).
