They tend to bang the drum when it comes to Intel but in AMD reviews you'll get things like "Due to bad luck and timing issues we have not been able to test the latest Intel and AMD servers CPU in our most demanding workloads". It's a lot like reviewing a Ferrari but due to bad luck you could only test it in city traffic.
2 years ago they forgot to cover the Threadripper launch for 2 weeks while the front page was flooded with dozens of uninteresting half page articles about Intel motherboards being launched around the same time. I love a good tech article regardless of which brand they're talking about but bias will always kill the experience for me. YMMV I guess.
