VERDICT
Recommended Core™ i9-7940X X-series
Enough margin to recommend, enough nuance to keep reading. 19 MB L3 cache, 14 / 28, up to 4.3 GHz explains why heavy loads stay smooth on Core™ i9-7940X X-series. The 46% edge in AI Capability is the usable takeaway. The largest practical gaps show up in 46% higher on AI Capability, Content Creation Index (~43% ahead)—if that is your week, Core™ i9-7940X X-series pays off. SFF builders: treat ~13% efficiency as a real constraint. The final word is your most-used software, not this page.
