Nvidia might be in the blame game with TSMC over Blackwell chip failures, but that doesn't mean it will go back to Samsung

pcgamer.com:

Although Nvidia's Blackwell chips are finally starting to line server racks—for example, Microsoft Azure servers—they're still arriving a little later than initially planned. But perhaps they should have arrived even later, as we're now hearing word that the chips might have been rushed to market too soon.

Tech site The Information (via Business Korea) reports that «during testing of the Blackwell chips in the weeks after Huang's announcement, Nvidia engineers discovered that the chips failed in the types of high-voltage environments that are common in data centers». This is supposedly according to «two people with direct knowledge of the problem».

The two sides are apparently blaming each other for this, with TSMC saying Nvidia rushed production and Nvidia saying the defects are due to TSMC's packaging tech. Whoever's to blame, the result seems to be tension in a three decade-long relationship between the two companies.

Which isn't to say there's been 30 years of uninterrupted partnership. Perhaps most prominently, the relationship was punctuated by an intermission for Nvidia's 30-series 'Ampere' GPUs, which it had Samsung produce. Now, The Information suggests that Nvidia could ditch TSMC for Samsung once again and hopes to receive a 20–30% discount compared to TSMC.

Yeah, and I hope for a 20–30% tax break. What, wishes aren't fishes?

I don't buy it. The fact is, TSMC is the only real game in town right now for Nvidia. It has more advanced process nodes and it doesn't have to reserve any of its fabrication for its own chips because it produces solely for third parties.

Plus, Nvidia's unlikely to have forgotten that the last time it partnered with Samsung, things didn't turn out so well, with skyrocketing prices and GPU shortages. Yes, unfortunate world events led to this, but the results were what they were and, unfortunately for Samsung, nothing can be done about that now.
