집에 있는게 2500이다 보니 이게 항상 기준이 되는데
회사에서 있는 녀석이 7600 성능비교를 보니.. 단일 코어 기준 140% 정도..
i5-9500은 150%에 멀티코어 사용시(6코어임) 200% 정도 성능
의외로 성능향상이 너무 더딘게 아닌가 싶을 정도..

서버 벤더에서 자사용으로 만들어서 쓰니 특정 규격이라고 할 순 없을 듯 하지만
Flex ATX 라는 규격이 그나마 비슷해 보이긴 하는 듯.

동일 모델은 아니지만, 서버 전원을 뽑아보니.. 별다른건 없고 PCI-Ex 슬롯 같은걸로 몇개 핀이 없길래 의아해 했는데
12V 단일 전압을 공급함으로서 전류를 높게 가지지 않아도 되니
PCI-Ex 슬롯으로 여러개 선으로 전류를 병렬로 전송하는 것으로 보인다.
| The R320 power supply subsystem consists of one non-redundant or up to two hot-plug AC-DC power supplies. The power supply provides +3.3V/5V/12V and +12Vaux for non-redundant design and provides 12V and 12Vaux for redundant design. There are several voltage regulators in the system to supply different voltage levels needed by different logic devices. The redundant power supplies are managed through a PMBus interface. |

75W 를 PCI-Express를 통해 공급이 가능하다는데
[링크 : https://www.geeks3d.com/20101108/tips-maximum-power-consumption-of-graphics-card-connectors/]
12V * 5 + 3.3 * 4를 적절하게(?) 분배해주면 대충 선 하나당 1A 정도씩 보내고 있다고 보면 되려나?
[링크 : https://en.wikipedia.org/wiki/PCI_Express]
750W 파워인데 12V로 보낸다면 12V * 62.5A 니까... 너무 높은데?
끽해봤자 20개 핀 + 넓은 면적인데, 데이터 주고 받는것도 있을테니 전부 쓰진 않을테고..
어떻게 보내는걸까?

i7-6700 / i5-7600 두대를 자리에 셋팅하고 쓰고 있는데
문득 성능차이가 얼마나 나나 궁금해서 보는데
i7은 L3 캐시 8MB i5는 6MB로 2MB 차이가 존재한다.
그 외에는 i7-6700이 구 세대인 관계로 100MHz 클럭이 낮다는 정도?
[링크 : http://www.cpu-world.com/Compare/427/Intel_Core_i5_i5-7600_vs_Intel_Core_i7_i7-6700.html]
아무튼 벤치마크 해둔걸 보면(4세대로 좀 다르지만)
L3에 영향을 받는 애들은 성능 차이가 꽤 나지만 그렇지 않은 경우는 유의미한 차이는 나지 않는다 정도로 보인다.
어쩌면 캐시용량을 넘어가도록 코드가 커서(즉, 최적화 덜 되서) L3까지 캐시를 쓰는 걸지도 모르겠지만
(즉, L2 인 1MB 이내에서 캐시가 히트 되는게 최적화 잘 되었다고 본다면)
비용 대비로는 그렇게 큰 효과가 있다고 보긴 힘들 것으로 보인다.

아 몰라~ 일단 작업관리자에 CPU 8개 뜨니 행복함 ㅋㅋ
