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?

옛날 글이고 18.04 / python3에는 아래 패키지를 깔아주면 되는 듯.
| $ sudo apt-get install python3-opengl |
| Install the distribution package as: sudo apt-get install python-opengl - this works for me. |
