E1380 = 5LPE 2.4GHz Cortex-A78
E1480 = 4LPP 2.75GHz Cortex-A78
대략 둘이 전성비 차이가 20% 정도 난다는 결론이 나오네요.
둘이 클럭 차이가 14.6% 정도 차이나니깐
만약 동클럭이었으면 전성비 차이가 30% 이상 더 크게 벌어졌을거 같네요.
이렇게 삼성이 설계한 SoC의 IP 기준으로 공정 성능 비교해보면
5LPE -> 4LPP 향상 수치가 나쁘지 않습니다.
이거 암만봐도
ARM 라이브러리 IP가 삼성 공정에 제대로 최적화되지 않은거 플러스
S.LSI 설계 리소스가 퀄콤 대비 많이 떨어지는 느낌이 강하네요...
같은 5LPE 공정 쓸때도 2100 CPU 대비 888 CPU가 좀더 나은 전성비였죠......

lsi는 그대로 갔다면 진짜 캐삭 당했겠군요...그나마 전용칩에서는 인력도 늘고 mx가 주도해서 사정이 낫겟지만요 ㅎㅎ
