i3-12100F  ~ ₹9200 ($105)

PRICE 

i3-12100 ~ ₹12,000 ($129)

* Core i3-12100 and Core i3-12100F are same. "F-variant" only lacks iGPU.

Core i3-12100/F Cinebench R23 Scores     single-core -1610  multi-core - 8400 

The 4-core i3-12100 beats 10th Gen i3-10100 by 30%  and Ryzen 5 5600G by 10%.

Core i5 11600K is marginally ahead, around 3.5% than i3-12100.

The i3-12100 won’t disappoint as a budget gaming CPU. However, things will change when Intel launches the Raptor Lake Core i3-13100 early next year.
