The JH7110 is a superscalar quad-core dual-issue design at 1.2GHz and has 2MB of L2 cache. The Core 2 Duo P8600 from late 2008 (around the same era you can buy Coreboot-able Thinkpads like my old X200) has dual 2.4GHz processors with 3MB of L2 on an OoO-superscalar design. It will probably lose handily, if I had to guess (strictly speaking, perf/watt may be better on the JH7110 due to newer manufacturing processes, but you're not using +15yo thinkpads if you care about that.)
