<h2 id="GPU란">GPU란?</h2>
<p>
GPU(그래픽 카드)란 CPU, 램, 하드디스크 등이 자체적으로 화면을 출력할 수 있는 기능을 갖추고 있지
않기 때문에 생성된 데이터를 영상 신호로 바꾸어 전달해주는 장치입니다.
</p>
<h2 id="GPU 종류">GPU 종류</h2>
<p>
GPU는 크게 내장 그래픽과 외장 그래픽 두 가지로 나뉩니다. 웹서핑이나 사무용, 간단한 동영상 감상등을
주로 한다면 CPU의 내장 그래픽으로 충분하지만, 고성능의 게임이나 작업등을 한다면 외장 그래픽을
사용하시는 것이 좋습니다.
</p>
<h2 id="GPU를 살 때 고려할 점">GPU를 살 때 고려할 점</h2>
<p>
GPU를 살 때에는
1) 스트림/CUDA 프로세서 : 그래픽 계산은 병렬 처리가 쉽기 때문에 같은 세대의 제품군 내에서는 프로세서의 갯수가 곧 성능을 결정한다.
2) 클럭 : 레퍼런스 제품군에 비해 높게 나왔다하면 해당 제조사가 팩토리 오버클럭을 했다고 생각하시면 됩니다.
3) VRAM : 3D 게임에서 보통 텍스처 데이터가 여기로 들어가기에 고스펙 게임을 즐긴다면 이것이 크면 좋습니다.
4) PCI-E : 최대 대역폭을 제한하는 것인데, 같은 최대 대역폭이라면 버전이 낮고 레인이 많은 쪽이 유리합니다.
위의 4가지를 고려해야 합니다.
</p>
<P>
이번 장은 GPU에 대하여 간략하게 알아보았습니다. 궁금한 점이 있으시면,
아래의 댓글란에 적어주세요:)
