According to BBC Sport, Neymar's move was priced at £48.6 million, while Bale's protracted sale cost a record £85.3 million, almost double as much.
Such a gap in fees reflects only on the vagaries of the transfer market; however, as they both begin life in La Liga, Neymar's value will rocket past Bale over the next few years.
The Brazilian has the luxury of joining the more settled club, where acclimatisation periods for the supremely gifted are minimal.
His vision, dribbling and passing skills make him a natural fit at Barcelona. He will find it easy to blend into the system, as he's already shown.
Neymar's was the decisive input in the recent Clasico derby, where he scored the opener and laid off an assist for Alexis Sanchez's stunning late finish.
That win has already given Barcelona a six-point cushion over their bitter rivals. Given La Liga's recent history, such a gap may already prove decisive.
The considerable impact made on the pitch, especially in that major clash, reflects on just how quickly Neymar's settled in, already able to influence games for the Catalans.
Bale is stepping into a team that relies almost entirely on individual brilliance over team ethics.
While he certainly possesses enough skill and flair to excel in most environments, making an impact in such surroundings—in front of 85,000 expectant people—isn't exactly straightforward.
His traits and style are hugely similar to Cristiano Ronaldo, making it difficult to envisage much successful chemistry in crunch games—a scenario that would only leave Bale in the shadows.
Such similarities on the pitch continually draw a direct comparison between the pair, accentuating their input to be some form of rivalry, which Bale could never win.
Instead of being seen to step on the toes of Lionel Messi, however, Neymar's already been clicking with the world's best player.
Their games are as much about creation and movement, as opposed to repeatedly looking to run and shoot. Their styles complement each other, they constantly interchange and are already terrorising defences when they play in tandem.
All this will lead to a more profitable season for Neymar, but it won't end there.
Fast-forward to the summer, and the Brazilian will suddenly be playing a leading role for the host nation at the World Cup, as Bale watches on from afar.
As his country's main man, likely success would propel the Brazilian to the very summit of the game, doing untold things to his confidence.
Even by this time next year, any estimation of these players' worth will have Neymar's value soaring past Bale.
As Ben Hayward writes for Goal.com, it was the Brazilian who was Real's initial summer target. While Bale should eventually perform well at the Bernabeu, Florentino Perez may forever rue missing out on Neymar.
