主要目的是打造加密货币全自动交易。但是又想玩一玩本地大模型。目前已明确模型就选择QWEN3.6 27B稠密。因为性能够用。相比GEMMA4 E4B与QWEN3.6 27B ，我个人的观点就是本地任务处理的天花板高度不一样，因为最终的深度数据分析还是主要靠云端模型。但是如果27B模型可以满足要求，我就可以实现全本地处理，同时因为个人兴趣的原因，还是想跑个本地模型，将来也可以扩展得玩一玩。</p>
<p dir="auto">看了京东上的产品，7900XTX还是保险一点，3090京东自营价格已经飞到8000了。所以我的问题焦点很集中了，7900XTX对我来说是否够用？先生的您的观点如何？</p>

理论上显存温度95°C没触顶，但是长时间高温硅脂干得更快。俺是舍不得这种烧，平时都将低显存频率+调风扇曲线，让显存在90°C上下。其实满功率跑，跑视频生产时间也就少5%<br />
