In addition the GE90's increased thrust was not yet required by airlines and it was also the heaviest engine of the three available choices, making it the least popular option on these first generation 777s (777-200 and 777-200ER, also known collective as the 777 Classics) while the Rolls-Royce engine was the most popular.

In February 2012, GE announced studies on a more efficient derivative of the GE90, calling it the GE9X, to power both the -8 and -9 variants of the new Boeing 777X.It was to feature the same 128 in (325 cm) fan diameter as the GE90-115B with thrust decreased by 15,800 lbf (70 kN) to a new rating of 99,500 lbf (443 kN) per engine.

They use the same type of engine across all models (GE 7FDL-8, except for UM 106T Locomotives which used Alco 12-244E). Despite using the same type of engine, the power capabilities from type to type are different as some models are equipped with dual turbocharger, or equipped with common rail system and dual turbocharger.
For comparison, some of the earliest GE90 engines aboard Boeing 777s kicked out 'just' 74,000 pounds. ... but the specs back it up as well: it has a whopping 11.2ft diameter front fan that ...
GEnx on 747-8I prototype. As of 2016, the GEnx and the Rolls-Royce Trent 1000 were selected by Boeing following a run-off between the three big engine manufacturers. The GEnx uses some technology from the GE90 turbofan, [1] including swept composite fan blades and the 10-stage high-pressure compressor (HPC) featured in earlier variants of the engine.
GE Aviation's offering is the GEnx, a development of the GE90. The engine was also the exclusive power plant on the Boeing 747-8. The Lynn facility continues to assemble jet engines for the United States Department of Defense, subsidiary services, and commercial operators. Engines assembled at this plant include the F404, F414, T700, and CFE738.
The GE90 engine runs the Boeing 777, and the GE9X will be the sole engine on the 777X. GE engines also power the Boeing 747, 787, and Airbus A330 widebodies.
The Engine Alliance GP7000 is a turbofan jet engine manufactured by Engine Alliance, a joint venture between General Electric and Pratt & Whitney. It is one of the powerplant options available for the Airbus A380 , along with the Rolls-Royce Trent 900 .
