最近被问到一个问题，如果为了Stable Diffusion绘画，应该本着什么原则购买显卡。
原则很简单：预算之内选显存最大的。
AI画图不要看所谓的天梯图，那个不适用。
具体来说，
不限预算，无脑上4090；
8000左右，4080，16G；
4000左右，4060Ti，16G；
2000左右，海鲜市场魔改2080Ti，22G。
尽量不要上30系，默认全矿。
其实4080我也不是很推荐，魔改2080Ti不适合普通玩家，出了问题不太好处理，重点推荐4090和4060Ti 16G。
尤其是现在SD进入了Turbo秒级出图时代，出图方面4090的优势没那么明显了。
如果你只是下载大模型，然后出图，4060Ti 16G非常香，但如果你想要训练自己的LoRA，训练自己的大模型，那4090还是独领风骚。
说的我自己都想换一块4060Ti 16G了。
C站的Turbo模型越来越多，今天推荐TurboVisionXL，版本是4.3.1。

哇，伙计们，你们一定要亲自尝试一下！
在“正常”XL分辨率下，超快速生成，质量远胜于基础SDXL Turbo！
最佳输出设置建议
采样器：DPM++ SDE或DPM++ SDE Karras
步数：3 - 5
CFG：1 - 2.25
您可以在Automatic1111中像普通XL模型一样运行此模型，但是并非所有采样器都适用于它。我发现DPM++ SDE在3-5范围内的输出性能最好，而DPM2在6-10步范围内的输出效果非常好，如果您愿意等待稍微长一点。LCM采样器和Euler A产生的输出几乎相同，适用于低步数，但在细节方面远不如其他选项。
LoRAS没有问题，我已经测试了多个LoRAS，它们似乎仍然产生预期的结果，当然，具体效果因个体而异。
此模型的连贯性还在改进中。1024 x 1024现在解决得相当好，即使在4:3和2:3格式中，我也很少看到错误。16:9确实会导致一些孪生现象，但还不算太糟糕。21:9更加粗糙，孪生现象和错误令人烦恼，但与普通主线模型相比并没有差多少。
