Yeah but it had less than 8 gb dedicated to gameing.
PS4pro has more dedicated to gameing, than the normal PS4 or PS4slim, because of that extra 1gb.
Even if its a minor differnce.

8GB was exactly dedicated to the APU ...
Just as how there's an extra ARM processor in the PS4, doesn't mean we should include it in our calculations for consistency's sake ...
No game developer is ever going to touch that 1GB of DDR3 just as how no game developer is ever going to use the extra ARM processor in either PS4 units ...

PS4 Pro uses just 5.5gb for gaming.
Cerny himself said in an interview:
On the standard [PS4], if you’re swapping between an application like Netflix and a game, Netflix is still resident in system memory, even when you’re playing the game. We use that architecture because it allows for very quick swapping between applications. It’s all already in memory.
On PS4 Pro, we do things a bit differently. When you stop using Netflix, we move it to the gigabyte of slow, conventional DRAM. Using that sort of strategy frees up almost a gigabyte of our 8GB of GDDR5. We use 512 megabytes [of that] for games, which is to say that the games can use 5.5GB rather than 5 GB. And we use most of the rest to make the PS4 Pro interface 4K, rather than the 1080p it’s been to date. So when you hit the PS4 button, that’s a 4K interface.
It's 9gb VS 5.5 which explains quite a bit, really.
