This processor is from 2007 and is a 2Ghz dual core with 2MB of L2 cache and no L3 cache. An AMD Ryzen R5 has 4 or 6 cores at over 3.5Ghz with 8 to 12 threads with 2MB to 3MB L2 cache and 8MB to 16MB of L3 cache. In Passmark the Core 2 Duo scored a CPU score of 1,161 and the Ryzen R5 1500X scored 10,739 and the 1600x scored 13,108. How can a ten year old bit of technology teach a modern quad and hexacore CPU a thing or two? Looks to me like this guy doesn't know a thing about PC's at all!
