I know it's common place but it's really sad they will physically disable existing already built functionality to sell it at a lower price.

Welcome to every binned die for the last... several decades. Per-core CPU binning has occurred since two CPU cores were placed on one die. Most of the time it's because the disabled area has a defect, but sometimes working cores are disabled in order to ensure a supply of a desired chip bin (e.g. the classic Athlon/Duron 'pencil trick' to re-enable disabled-but-good cores, or sometimes cause the machine to fail to POST due to attempting to enable a dead disabled core).

It's mostly because of binning that these products exist at these prices.

Either really, really crap editing, or new terms that I don't understand. Or, AI made article?? What is "re-spinned"... Actually, whole thing seems a bit 'off'.

will lack a direct successor to Nvidia's highly-successful AD104 chip

Ummm... since when?

It's crap. It makes little sense. There is WAY too much speculation, based on such little info from a leak.
But the strangest part is that bit about having to throw out AD103s if they have a single defective CUDA core. The author doesn't seem to have a full grasp of binning. The RTX 4080 already IS a cut-down AD103 die. It uses 76 of the AD103's 80 SMs (9,728 out of 10,240 CUDA cores.) If a single SM or CUDA is defective, they can use a different one that would have been fused off anyway.

This is weird.

Nevermind that GTX900 series is made up of GM2xx cards (and GTX700 series being made up of GK2xx cards which was hardly a respin)
Which is a optimization of the original Maxwell architecture
Wow tomshw is certainly getting worse

re-spins are basically just revisions to the silicon. In this case they mean the photo masks, which is to say the circuit layout. Since these haven't been manufactured yet (to our knowledge), re-spinning is unusual. Also, it means architecturally speaking, the devices would be similar to the ones before it (100 series) but maybe include bug fixes, enhancements, or performance improvements.

I still remember when people were trying to flash RX 480/580 bios on RX 470/570 to try and unlock any locked down cores. and in rare cases it worked. People were sharing the lot or S/N of the GPUs in reddit to gain an ez boost...

That was a tradition that went back to at least HD6950
Often times they simply weren't lasered at all (common theme with AMD going back to phenom 2/athlon 2 three cores being unlocked to quads, even the later quads were unlocked to hexa cores as well) and repurposing cast off bins therefore you could easily unlock them

Ever since AMD got their act together they have been putting programmable fuses properly, before that they were more unintentional to end up with poorer bins rather than their aim to create more bins
