I wonder version is more poreful compare to my old Co2 gun?

muzzle energy is just mass*velocity*velocity
Except when talking guns mass is usually in grains (7000 per pound) and you are working in feet per second, and the NRG value is expressed in ft-lbs so there is a bit of unit conversion math involved before you can run the three multiplication operations.
My pump crossman pistol certainly outperformed my crossman CO2 pistol *unless* it was a hot day and the CO2 cartridge was fresh (first 20 or so shots)
If you want to play with the big boys you can get into larger calibers and PCP (precompressed, so you are feeding w/ scuba tank or similar or a compressor capable of putting out 2k+ psi). Saw one guy at the range, the price he quoted on his rig was "new small car or maybe a machine gun" but then it would monitor gas pressure, allowed dial-a-velocity, auto-adjusted scope drop based on bullet weight/BC and velocity, was suppressed, etc. Shooting much smaller 50 yard groups than I was with my 10/22 build. His was 22 caliber since he only did target stuff....
