Memory Performance
At the top of the chart we see the 12th Gen CPUs that run on DDR5. They are followed by Ryzen 9 and the Intel CPUs running on DDR4. At the bottom we have the single chiplet Ryzen 5 and Ryzen 7. Once you understand those big divisions it is clear that Core i5-12600K sits up in the DDR5 group but comes in below the new Core i7 and Core i9.
On the one hand the new DDR5 has huge bandwidth while on the other hand the latency is slow. This uncomfortable fact pushes the Core i5-12600K towards the bottom of this particular chart.
