No they are not the same. The Sport Chrono package does 2 things, increased throttle response with less pressure on the pedal and tunes down when PSM kicks in. If you have PASM it may also make the suspension stiffer but I can't remember with certainty.

A chip updgrade may also do these things but is primarily intended to get more horsepower of the car by remapping whatever they can electronically to claim more HP. It's also a great way to void your warranty or at a minimum make your warranty claim a miserable experience if you have any problems with the car related to the engine, exhaust or electronics. Porsche can detect a different chip. You may be able to replace it with the original if you have problems and take it in but if they still are able to detect the chip was there, ask you if you had a chip and you say "no" well that's fraud and the warranty coverage conversation will likely end right there until you hire a lawyer. I'd only chip a car if it was out of warranty. "Just because I'm paranoid doesn't mean they're all not out to get me."

I'm curious how you're planning on "installing" Sports Chrono. It's not available as an add-on, software or otherwise from the other 220+ dealers in the US.

I found out its not possible.
Although a GIAC ECU reprogram might get the same effect or even better , according to some tech guys.

Improvements from chips/ECU modifications are suspect at best and normally predicated on running high octane fuel, a shortage of which is apparently already plaguing you in the CR, per your other post. I suspect this would be a monumental waste of money in addition to any flack you'd get from Porsche per 1JB's post.

Porsche has taken the same 2.7 mill that originally produced @217 hp and have managed 8 years later to get 245 hp out of it. Frankly, I think they've pretty much wrung ever hp out of it and the 3.2. Note that to get 15 more hp into the S they actually ended up bumping the displacement (not the only reason, but you get the point).
