上个月，科技圈发生了一件大事儿，说的是英伟达将投资50亿美元，收购英特尔的部分股份，两家也一起发了声明。 这个事情的发生就很微妙，因为最近英特尔过得并不好，CPU 干不过 AMD ，GPU 干不过英伟达，而这件事发生之后，英特尔多少是可以稍微喘口气 了。 但是呢，这不是我们今天要讨论的话题，因为这次我们要测的产品不仅出自英特尔，而且它还是英伟达显卡的竞品，是不是听着有点抽象。。。 没错，它就是英特尔推出的 GPU ——Arc B580 。 实不相瞒，经常关注数码的差友们应该已经看出来了，其实这是一期炒冷饭评测，你这 B580 都出来多久了还拿来测？ 其实我们本来是没打算这么干的，但是前两天我们有位同事打算装机，要求其实也不高，就偶尔玩玩网游啥的，预算也不高。 他本来是计划买一块最新的入门卡英伟达 RTX 5050 ，然后就发现这玩意儿起售价居然要 2099 元，性能还不如 RTX 4060 。。。 结果我们在这个价位扫了一眼，发现性价比最高的选项，居然是扔在影棚角落吃灰的这块英特尔 Arc B580 。。。 于是乎，秉承着来都来了的原则，我们就干脆测了一下这块儿一直在吃灰的显卡，也希望能借此改变一下大伙对英特 ...
