The already small 3% margin favoring AMD at 1080p shrinks to 1% at 1440p. On average that's identical performance, if we couldn’t say that already at 1080p. Our launch review of the RX 5600 XT showed something similar, so it seems we did well with a dozen game sample that was very representative of what we see here with 32 titles.
What to Buy
Bottom line, the 5600 XT and RTX 2060 are very evenly matched in terms of performance. As it's usually the case when we see this kind of result, the best option for you will probably come down to the games you play.
The two GPUs are so evenly matched that it prompts us to consider
the driver angle, especially with a large base of users reporting issues with crashing and black screens over the past few months. At least in the short term, it should be a concern and it makes recommending the 5600 XT quite difficult. The RTX 2060 is a proven product at this point, it offers a similar level of performance, and generally costs anywhere from $10 to $30 extra which is a tiny price to pay for stability
