I understand the question is broad. On my screen, a Radeon 270 would handle High Setting reasonably well on a 1280 x 1024 display. Mantle can boost BF4's FPS noticeably, but whether it's better than DirectX depends on your specific needs and preferences.
It could perform well at 1080p; Ultra would be ideal and deliver excellent frames.
I realize I’m missing a 1080p display, so Ultra should work fine. Mantle seems capable of handling BF4 even though it’s still in beta—I think.
Simple 60+ frames per second on low resolution with ultra settings.
