just your opinion / speculation / wish / hope / prayers is what I think you on.
Devs usually design games on consoles to work best with the hardware the consol uses correct?
but if the CPU is weaker than the rivals..... what then.?

and TBH I thought you were trying to go here..

so if they made a straight port to pc it would be a multithreaded game and utilize more cores...

Is this why the games ported from the 1 PPE 8 SPE cell and the Xenon with 6 logical CPUs are so well multithreaded today and have been for the last 7 years?

To quote tom's/AMD on what is actually inside the PS4:
First of all, Jaguar is very much a different design compared to BD/PD and ever SR and no one is running Jaguar as their gaming CPU on a desktop PC, secondly it seems to me like the chip is quite customized, including a bunch of parts for specific purposes.

You are missing the point. The port will be optimized for 8 cores. The FX has 8 cores. No Intel CPU has 8 cores. Therefore the port will be better suited for AMD chips. This was not the case with previous console chips. If they had multiple cores they were not all being utilized.

Well those weren't x86 cpu's actually they were based of the powerpc architecture of IBM.
The P3 which the original xbox360 was based of was single core ofc.

Those console CPUs had reserved cores in them that were used for purposes other than running threads. This is not the case with the Jaguar cores.

your missing a point too.
the AMD CPU is weaker and I rather and the Intel mainstream solution is still going to be stronger than the AMD MOAR CORES solution.
that's how it is already and when you overclock the AMD and Intel chips the Intel chips will pull farther ahead because of stronger cores / IPC..
just because the code is written to utilize all 8 cores doesn't mean all 8 will be utilize at all times anyways.
and that's still a ways away..

It's not that simple.

Core count doesn't matter, overall performance does. If intels 6 cores beat AMD's 8 by well over 50% there's pretty much nothing that good multithreaded code can do for that. If a 4 core 3770K beats a 8350 even in multithreaded scenarios where all cores are being used, ultithreaded code will not make the FX better than the i7. And this is in a purely hypothetical scenario where the load is 100% parallel, scenarios like this don't exist in gaming for CPUs.

I'd also like to point out that 8 Jaguar cores =/= 8 BD/PD/SR cores, there are some huge architectural differences. And also pointing out that there are 8-core intel CPUs.

True however I think you're overestimating the difference that makes when it comes to games being multithreaded or not. Fact of the matter is that games do offload certain tasks to quite many cores but there are just parts of games that aren't parallel like that.

For the cell? Yes. For the Xenon? Not as far as I know, correct me if I'm wrong though.

I'd also wager that at least one of the Jaguar cores will be used for the OS or other functions (recording, livestream, social) on the PS4 but that is of course yet to be seen.

look at BF3 for example.... AMD's "weaker cores" run that game better than intels "stronger" 4 core 3570k.... MoH warfighter is the same way, sme with crysis 2-3....

Very true statement I just hope to see more of it in the future as I move up the Mission Critical scale where there are many cores but low clocks and 1 gen behind so only higher threadedness(I made up that word) can keep me from bottlenecking.
Even my e5520's are killing me and I mostly lock them down to 2 cores per cpu HT disabeld so I can get 4 cores at 2.533GHz which doesn't neck my gtx570 that hard.
