The safest bet would be the 6700 XT or RTX 3070 as those would guarantee 144 Hz at 1080p even at high settings.

To summarise, Call of Duty Warzone works very well with a GeForce RTX 3060 Mobile. While it can comfortably perform at 1080p we know it is best served at 1440p resolutions and could possibly go up to 4K with some settings adjustments.
