Did you read anything I wrote? Jaguar is a netbook CPU at 1.6 Ghz. If Sony used an i5 level CPU it would run circles around Cell. The other problem is that the Cell numbers are using the SPEs. The PS4 can use the GPU to perform calculations. Try to compare the puny 6 SPEs of the Cell with a few hundred GPU cores doing number crunching. That was the point that made Cell obsolete (even for HPC): GPUs simply destroy the SPEs in the massively parallel tasks both are supposed to do.
It's also insanely naive to simply compare brute floating point numbers, since this is not the only operation these CPUs are supposed to do for games. What about cache access? And specific instructions? Branch prediction (Cell doesn't have it)?
Cell is a single core CPU with 8 SPEs. Jaguar has 8 real cores. The SPEs can do numeric operations, but that's pretty much it. If i want my CPU to run an AI routine, the Cell can only deal with one thread since the SPEs are SIMD. Jaguar could run 8 threads. Basically floating point operations are the only thing Cell beats Jaguar. Any stuff that creates ramifications or recursions can't (shouldn't) be done on the SPEs. They also have limited memory access. They are simply 1% of a GPU crammed on the CPU die.
The SPEs work like GPU cores (again, SIMD). So, it doesn't help when you can simply use the GPU itself with hundreds or thousands of cores to do the operation.
