class=post-body itemprop=articleBody><p>之前在我的3060笔记本上试了有显卡的情况下gpt-oss的表现，只能说勉强可以用，比mbp上是可用了很多，毕竟那玩意除非完全把内存都让给gpt-oss，不然都跑不起来，只是生成速度还是有点感人，差不多就4.66token/s,一直觉得能在本地跑个稍微能用点的模型还是种比较不错的体验，所以在最近买了个5060TI，因为这个是最便宜的16G显存的家用显卡了，当然排除各种魔改卡，比如镭7这种，当然喜欢折腾的也可以买来玩玩，硬件上要玩起来还是需要比较多时间的<br>今天用同样的prompt来再对比测试下<br>3060 6g笔记本显卡<br>prompt是<br><code>帮我用react写一个todo应用，样式要美观精致</code><br>我们先对比下效果<br><img data-src=https://img.nicksxs.me/uPic/sCyypJ.png><br>生成的还是比较简介，重要的是正确的<figure class="highlight shell"><table><tr><td
