Both consumer and server processors from Intel show the gap. For consumers, all PCs or laptops with Intel Core processors of the 6th “Skylake” generation up to and including the 11th-gen “Tiger Lake” chips contain the vulnerability. This means that the vulnerability has existed since at least 2015, when Skylake was released.

Intel’s corresponding Xeon processors are also at risk to Downfall. Due to Intel’s dominant position in server processors, virtually every internet user could be affected, at least indirectly.
