Spectre is just about timing attacks on branch prediction. It has nothing to do with transistor density, and it can be remediated with a reasonable impact on performance, that is if remediation is necessary. These vulnerabilities are also hard to exploit in real life and not always relevant. Rowhammer has to do with RAM density, but again, hard to exploit and there are mitigations.
