CPU core count
GET /api/fingerprint/hardware-concurrencyHardware concurrency fingerprinting detects the number of logical CPU cores via navigator.hardwareConcurrency. This reveals device performance tier: 2 cores indicate budget laptops or older devices, 4 cores represent mainstream consumer hardware, 8 cores suggest high-end consumer or entry-level workstation devices, 12-16 cores indicate professional workstations, and 24+ cores point to servers or high-end workstations. This value correlates strongly with device purchase price and user demographics. Professional users (developers, video editors, 3D artists) typically have higher core counts. Mobile devices report 6-8 cores (efficiency + performance cores on ARM). This metric is extremely stable unless hardware is upgraded.
