IIRC, the playground builds also had a 64bit build ( though, not sure). Someone will probably provide more info on that. And, about the minimal differences in speed. I had already asked Rama on the difference between a X64 bit build and X86 bit build and many said that there will be only a little amount of improvement. To back up my statement, here is a quote from ref.

There is no benifit for us with 64bit, we "shouldn't" need the extra memory space and the 64bit instruction set will provide such a small benifit it is completely overshadowed by the work involved.
We're supposed to be working as a team, if we aren't helping and suggesting things to each other, we aren't working as a team.

Well, we didn't have x64 builds, and we can't know how much better they might be because it hasn't been tried yet. The assumption is that it will bring little benefit, and it's not easy to make it happen. However, until someone manages to make it build in 64 and actually compare - we don't know how much they'll differ.

Yeah, you're right. Theoretical assumptions can't be precise all the time. Though, it does give a rough understanding on the expected performance of X64 builds. Still, I wouldn't expect any major differences from X86 builds since, there are no factors for that to happen practically.

Well, these are from almost 10 years ago, and there's probably a good reason they didn't stay for more than a day... so back to my original claim that we can't know how modern PCSX2 will perform as 64b without making it first build and run in 64, and it's unlikely that those 8 years old experiments will add any relevant info.
