Spectre is a hardware-level vulnerability that exploits a processor optimization technique called speculative execution.
As of 2026, the performance gap still favors Ghost Spectre for older hardware. While regular Windows 10 is better for security and stability, Ghost Spectre provides a superior experience for gaming or general productivity on limited hardware.
Partially, in theory. But fully updated Windows 10 + patched CPU microcode + modern browser = very low real-world risk.
