They have 125,000 employees and 13B in revenue. TSMC, Nvidia, and AMD combined (fab, GPU, CPU) have around 88,000 employees on 710B in revenue. Intel may honestly have far more headcount than they need.
Intel also have or had a wide variety of side businesses - compute sticks and NUCs, NICs (WiFi, Ethernet, optics), datacenter SSDs, and probably other things I'm forgetting.
