Intel was well on its way to be a considerable threat to NVIDIA with their Arc line of GPUs, which are getting better and cheaper with each generation. Perhaps not in the enterprise and AI markets yet, but certainly on the consumer side.
This news muddies this approach, and I see it as a misstep for both Intel and for consumers. Intel is only helping NVIDIA, which puts them further away from unseating them than they were before.
Competition is always a net positive for consumers, while mergers are always a net negative. This news will only benefit shareholders of both companies, and Intel shareholders only in the short-term. In the long-term, it's making NVIDIA more powerful.
