本地部署LLM，目前主力模型是27B FP8。<br />
配置：5060ti*4 + trx40 + 3970x线程撕裂者 + DDR4 UDIMM 128g 3200 ，windows + ubuntu ，家属用windows办公，我用window打游戏。<br />
还有128G DDR5 UDIMM 5600，闲置。<br />
<strong>装备图</strong>，走线稍微乱了点......<br />

<p dir="auto"><strong>运行27B 推理，测速 和 nvtop</strong><br />

<p dir="auto">PC2：<br />
AMD H370 迷你主机，32G DDR5 放在另一个房间，低功耗跑agent，ubuntu</p>
<p dir="auto">PC3：<br />
MBA M3 24g ，写代码用，SSH PC1 or PC2</p>
<p dir="auto">我的分析：<br />
nvtop看出，GPU和MEM 长期99%。<br />
5060ti tp4 ，cuda核心 = 4500 * 4 = 18000 ,  prefill阶段，all prompt 可以并行计算QKV，现在2300 tps的prefill基本极限了？除非升级显卡算力？<br />
decode阶段，看内存带宽。tp4总带宽 = 450G<em>4 =1800G,  模型总权重 27B FP8 = 30G ，decode = 1800/30 =60 tps，扣除tp通信损耗</em>0.7 = 40tps，打开MTP or Dflash2，可以提升到50-80 tps，也达到极限了？</p>
<p dir="auto">虚心请教大佬意见，如果提高LLM性能，还可以升级什么？升级下显卡？主板？CPU？现在这些都很贵了，有没有性价比方案？还是再组个windows办公算了？</p>
