For comparison the Saturn V's F-1s were running at 70 bar. They produced so much thrust each by being so freaking big.
One of the best metrics I've always liked about a liquid rocket engine is thrust per square meter of surface area.
The F1 has a diameter of 3.7 meters and generates 6.77MN. That's a surface area of 10.75 square meters or 0.63 MN per square meter.
Raptor2 has a diameter of 1.3 meters and generates 2.00MN. That's a surface area of 1.33 square meters or 1.50 MN per square meter.
BE-4 has a diameter of 1.9 meters (I think, harder to find numbers) and generates 2.4MN. That's a surface area of 2.833 square meters or 0.85 MN per square meter.
Merlin has a diameter of 0.92 meters and generates 0.85MN. That's a surface area of 0.66 square meters or 1.29 MN per square meter.
The RS-25/SSME has a diameter of 2.4 meters and generates 1.86-2.27MN, let's call it 2.0MN. That's a surface area of 4.52 square meters or 0.44 MN per square meter.
The STS SRB's have a diameter of 3.7 meters and generate 14.7MN. That's a surface area of 10.75 square meters or 1.37 MN per square meter.
The thing to keep in mind about a rocket engine is that it has to push the column of mass directly above it. If the mass*gravity is greater than the engine's thrust, it's not going anywhere. The stronger an engine is per square meter, the taller or heavier the column of fuel and payload can be above it, or the wider its column of responsibility can be for the total payload of the rocket.
BE-4 is kind of a depressing engine. Less force-efficient for surface area than Merlin, let alone Raptor2. It's barely half the engine that Raptor2 is.
Raptor2 is insane. More thrust per square meter than a Shuttle SRB.
