小身軀大能量:12代小核Gracemont完全評測

眾所周知, Intel在12代首次引入了大小核架構, 並將其中兩個大核的面積換成了8個小核, 那麼這些小核的實際性能又是否值得?
本測試將通過開啟和關閉12900KF的8個小核, 從而研究小核Gracemont的實際性能
測試平台1:
12900KF P Core 5.0GHz, E Core 4.0GHz
DDR5 5200C38 32GB
ROG Z690 Apex
ROG 3090 Strix OC
測試平台2:
12900KF P Core 5.0GHz
DDR5 5200C38 32GB

總結, 8個4.0GHz的小核大約等同默頻的8700K, 最多可以提供43.9%的加成, 最少可以
供31.1%的加成
平均而言, 4.0GHz 8C8T的Gracemont擁有38.7%的8C16T 5.0GHz的Golden Cove的性能, 卻只增加了18.9%的功耗, 可謂真正的"小身軀大能量"
