Not sure why am trying to convince for a rumor I don't believe myself but here goes :
Well the dev kit appears to have 2 sets of vents - in a design that's hard to make sense of unless it has 2 heatsinks ..
IF it's dual 36CU GPU it gets to nearly 14TF at just 1.4GHZ - at those clocks the GPU power is ~80W only, 160W for both (that doesn't include everything else) .. it's suprisingly low though ..
If it's integrated onto a single chip ala chiplets then you only need one heatsink .. (also see above)

Better bookmark that, not sure if I can find it again
Agreed, the two sets of vents can lend some credence to a dual GPU setup, but you can't hit 14TF with 72CUs @ `1.4GHz...you'd get near 13TF however. 14 would need a larger bump in clocks or more CUs activated.
However, aside from the relatively low TDP that setup would provide at 1.4GHz, it still wouldn't answer the question of why go with dual GPUs at that size and at that low frequency for that additional cost to the BOM which would certainly be more than having a single 60CU GPU clocked higher and within its sweetspot territory providing similar performance, but at a lower BOM?
...So I did think on it a bit more, and there's maybe one (admittedly crazy, possibly) reason to go with a dual Oberon/dual 36CU setup, even if the cost would push up the BOM and the MSRP. Maybe...they could do an optional cooling upgrade kit, to install in the system, and allow the GPU clocks to be increased safely and provide more power?
It would basically be the same system but by installing a superior cooling system/peripheral the clocks could get increased through a patch to change BIOS settings, and that could take it from a 12-13TF system to a 16TF "PS5 Pro" system with the simple swap? That way the base model can still be released at a competitive price, and with the optional cooling upgrade (the cooling in the base system would have to be modular, so that literally anyone can just go in and swap the parts out) you let the GPUs perform in their sweetspot zone or slightly higher and get the optimal performance out of them, giving extra headroom that the system can utilize automatically for other games like improving the framerates, or helping with texture streaming etc.?
Like I said it's just a crazy idea, but it's the only semi-logical reason I can see going for a dual-Oberon GPU setup in PS5 that justifies the super-low clocks at base, and gives a pathway to optimal use of the spec with optional better cooling to give more breathing room for higher clocks, giving it a substantial performance over base PS5 and XSX and acting like a soft "PS5 Pro".
Plus, that kind of optional cooling kit upgrade peripheral would be priced lower than a separate PS5 Pro model, meaning a larger chunk of the base will potentially buy it, meaning more justification from developers to design specific performance targets in newer games that can take better advantage of systems using the peripheral. They could even include it as a bundle in a secondary PS5 model around launch or a couple years down the line, and that would STILL be more affordable than a separate PS5 Pro.
...and let me just say again this is a crazy theory of mine, and I'm trying to fit it within the realm of other possibilities o PS5's specs which I feel are more realistic/probable to actually happen.

was talking about " I believe " , and if you ask me why .. just blame Sony not RAD
