You don't even need a Core i5.
Jaguar is around 10-20% faster than Brazos per core, with 8 cores it would be equivalent to roughly a Dual-Core Hyper-threaded Haswell Core i3. The reason why PC's have historically required faster CPU's than the console equivalent is because of draw cells, which are soon to be essentially a thing of the past.
Also something to keep in mind is that even AMD's fastest CPU's pale in comparison to even some of Intel's slowest, even with twice the cores in AMD's favour. Besides the Playstation 4 and Xbox One don't allow for all 8 anemic cores to be used for gaming anyway.
Jaguar is a 2 issue, low clocked, low IPC, small caches (No, L3) with pretty poor Floating Point and Integer units. It's a budget processor which is designed to be "good enough" not class leading, Microsoft and Sony spent all their transister budgets on the GPU and other subsystems, not the CPU. If Microsoft and Sony wanted decent CPU performance, they would have to pay for it which is not ideal in a cost sensitive device, which means higher cost consoles for all the consumers who would have then complained untill the cows came home.

Really? ... You're stainding buy the bolded??
Elsewhere: Remember that PC games are still not optimised for many cores (the logic being that not everyone has an 8 core CPU yet).
All new gen console games are being optimised for 7 (there you go), cores right now. Still, not the fastest CPU and there's no problem with that(yet).
Unified Memory Architecture the PS4 has, not any gaming PC yet. One is clearly superior to the other (not the PC one).
I hopen Mantle will be awesome, but it will not eliminate the advantage that consoles have over PCs (no matter the OS) in matters of optimisation. Fixed hardware and the option to learn to do whatever the fuck you want with it for the win.
Remember this (and if in doubt, look at the evolution of games on the PS3 from a graphical point of view all the way untill this year):
Amazing looking games are coming to the PS4 in the future.
Amazing looking games are coming to the PC in the future, BUT one will have to upgrade the PC for them.
