The Reuters sources say that Intel and its foundries division were bidding competitively against AMD and TSMC for the PS6 chip sometime in 2022.
Pfft. If you just think back to the state of Intel's dGPUs in 2022, it's hardly any surprise they lost it! Their GPUs looked good on paper, but woefully underprerformed according to their specs (and they still do, in many cases). You can't prove it was just the drivers that were at fault, until you actually fix the drivers, and that didn't even start happening until late 2022.
Then again, the article does cite financial disputes as the deal-breaker. However, if Intel had the same kind of GPU track record as AMD, I have to wonder whether it'd have strengthened their hand in the negotiations.

The chip design and manufacturing foes, the last contenders with hope for the lucrative contract after Broadcom was sidelined
Again, this is laughable. I can't fathom how Broadcom hoped to compete on the GPU front. The only
real contender would've been Nvidia. Since Sony was considering Broadcom, they must apparently be considering an ISA switch to ARM or RISC-V, which would definitely open up the field to include Nvidia (if they even wanted to bid).
I do sort of doubt PS6 will be backwards compatible with PS4, however. And this is probably due to the GPU ISA, not the CPU. PS4 was GCN-based, and RDNA has (thus far) included GCN backwards compatibility, but at what cost? It wouldn't surprise me for AMD to drop that, in RDNA 4 or 5 (or the subsequent UDNA that AMD recently announced).
