Yes, Intel and AMD can still hold desktop dominance near term, but the moat is now clearly weaker.
NVIDIA’s RTX Spark is not just a chip launch. It combines Arm CPU, Blackwell GPU, CUDA/RTX software, Windows AI agents, and OEM support from Dell, HP, Lenovo, Asus and others. That attacks the PC market through AI performance, not traditional CPU benchmarks.
But x86 still has major defences: app compatibility, enterprise fleets, gaming support, existing supply chains, and years of OEM optimisation. Most users still buy PCs for price, reliability and compatibility, not local AI agents.
My view: Intel is more exposed than AMD. AMD has stronger execution and GPU/CPU credibility. Intel’s moat depends heavily on legacy x86 share, manufacturing recovery and enterprise stickiness.
So, not an immediate x86 collapse. More likely: NVIDIA captures the premium AI PC niche first. If Windows-on-Arm compatibility improves and AI agents become genuinely useful, Intel/AMD lose pricing power over time. This is a strategic warning shot, not a knockout blow yet.
