VERDICT
Recommended Core™ i5-12400
This pair rewards checking indexes more than re-reading the total. 18 MB L3 cache, 6 / 12, up to 4.4 GHz explains why heavy loads stay smooth on Core™ i5-12400. The 25% edge in Compute Index is the usable takeaway. Budget or bundle deals can flip this pair despite G-SCORE. Electricity-heavy regions should price in ~58%. The final word is your most-used software, not this page.
