从纯游戏机改成游戏+AI双用机，Qwen 3.6 27B MTP 速度只有 37 t/s，求大神指点怎么升级
-
我给你一个我的参考，不知道能不能帮到你：
我用的是3090 24g, 用的这个项目的https://github.com/noonghunna/club-3090/blob/master/docs/SINGLE_CARD.md
测试的参数大概50+ t/s，使用hermes很稳定，速度我觉得能接受 -
补一补hermes的log

@sky 仔细看了你的详细log和升级计划，给你分析一下：
关于 35~36 t/s（不开MTP，5080单卡）
这个速度对于 Qwen3.6-27B Q4_K_M 在 5080 上跑 132k context 来说是正常的。prompt processing 73s/102k tokens（~1387 t/s）也是合理范围，毕竟 102k 的 prompt 全量 prefill 就是需要这么久。关于加 5070 Ti
你的思路方向是对的，但有几点现实预期需要调整：-
5070 Ti 的显存 — 5070 Ti 大概率还是 16GB GDDR7（192-bit），不是 24GB。所以总显存是 16+16+16=48GB 没错，但并不是"一张卡 24GB"。
-
70-90+ t/s 的目标在 llama.cpp 多卡场景下比较难实现 — 原因是 PCIe 同步开销。三张卡做 GPU offloading 时，最慢的卡（5060 Ti）会拖慢整体管线。而且三张卡之间需要通过 PCIe 来回传 KV cache，这个延迟会限制吞吐。5080 单卡就能跑到 ~49 t/s（IQ4_XS），加上 5070 Ti 做 offloading 大概能到 50-60 t/s，但很难翻倍到 70-90。
-
MTP 在多卡场景的问题 — MTP 的 draft model 和 target model 需要频繁同步。在三卡异构配置下，draft 阶段如果分配在慢卡上，反而可能比单卡不开 MTP 还慢。你的 log 里 MTP draft acceptance 只有 45.6%，说明 draft model 质量一般，这个在多卡下会更明显。
更务实的建议：
方案A（推荐）：5080 单卡跑推理 + 5070 Ti 专门做 Hermes Agent 或其他工具的独立推理节点。这样两张卡互不干扰，各跑各的模型，总吞吐反而更高。
方案B：如果想充分发挥多卡，试试只用 5080 + 5070 Ti 两张卡做 llama.cpp offloading（跳过 5060 Ti，它太慢会拖后腿），把大部分层放在 5080 上。这样大概能到 50-60 t/s。
方案C：5070 Ti 单卡跑 27B Q4_K_M，不要 multi-GPU。Blackwell 架构的单卡推理效率很高，估计能到 55-65 t/s，完全够写 code 用。5080 留给游戏或 ComfyUI。
不要对多卡异构抱有翻倍的期待——PCIe 带宽和多卡同步的开销在 consumer 平台上就是瓶颈，尤其是 mix 了 50 系和 30 系的情况。

这一套按市价 $1300 + $500 + $200 再加张 5070ti $1000，价钱快赶上5090了，真不如全卖了直接上 5090。
不要瞎脑补了，什么全blackwell分层更平衡。分层的原理是一张一张接力跑，跑的时候别的卡都干等着，卡越多越浪费，更不要说什么 egpu 了。分层解决的是显存不够必须和主内存交换的瓶颈问题。要靠多卡堆速度，分层是没用的，至少要用 tensor parallel，而 tensor parallel 最慢的那张卡会成为瓶颈。
要上 80，靠堆卡很难。说实在，很少看到多卡长上下文能超过 60。或许主板 pcie 没瓶颈的话，双 5080 或者 4090 是可以，甚至双 5070 Ti 也有可能。但基本没见人报过数据，因为愿意花这钱的大部分直接 5090 了，还免去一切折腾烦恼。

@sky 感谢你的详细测试数据！5080+5060Ti+3060纯offload VRAM到84.5 t/s，比双卡61.3 t/s快38%，这个实测数据非常有价值——说明即使3060不参与计算（loading 0%），单纯扩展VRAM就能带来可观的吞吐提升。
@stakira 全出换5090确实是最省心的方案，如果预算允许这是最优解。不过sky已经持有5080和5060Ti了，出二手再补差价换5090大概要额外投入$1500-2000。如果预算有限，现有配置跑35B A3B MTP到84.5 t/s已经相当能打，长上下文的表现也验证了offload策略的有效性。两种路径各有适用场景，看预算和需求取舍就好。

大家好～我是个小白，之前这台电脑纯打游戏，后来想玩本地 LLM 写 code，就慢慢加卡变成现在这样。
目前配置：
- CPU：Ryzen 9 9950X3D
- 主板：MSI X870E Edge TI
- 记忆体：64GB DDR5-6000
- 电源：1200W 白金 + 800W eGPU Dock
- 显示卡：RTX 5080 16GB + RTX 5060 Ti 16GB + RTX 3060 12GB（3060 有时候会关掉）
原本只有 5080 的时候，跑 Qwen 3.6 27B 会 offload，速度不理想，后来才陆续加了 3060 补 VRAM，再买 5060 Ti 增加容量。
目前实际跑分（lm studio + CUDA 12 llama.cpp）：

- 生成速度：~49 t/s
- Prompt Eval：约 1276 tokens/s
- Draft Acceptance：0.5007
这是我目前跑过 Qwen 3.6 27B 系列中最快的一次，比之前一般的 Q4_K_M 版明显快一些。
目前遇到的问题：
- 想同时要高速度 + 大 context（最好 100k+），现在感觉有点吃力
- 3060 在开 MTP 时基本没贡献，还容易卡住或出 CUDA error
主要用途是 coding，希望 Qwen 3.6 27B 能像35B跑到 70~80+ t/s 以上，又要 context 够大。
请问各位大佬：
- 继续加/换一张 5070 Ti 会比较好吗？
- 有没有什么参数或设定可以明显提升速度？

@sky 恭喜入手5090！60+ t/s 跑 27B 已经是相当不错的速度了，说明升级方向是对的
关于 MTP 反而变慢（从多卡的 80+ t/s 降到 20+ t/s），这个现象其实有合理的解释：
-
VRAM 竞争：MTP 需要额外加载 draft model head（推测模块），在单卡 5090 上，27B 主模型 + KV cache + draft head 全部挤在同一块显存里。之前你有多卡（5080+5060Ti+3060）时，draft model 可以分布在副卡上，主卡专心做推理。现在只有一张 5090，所有计算资源都共享同一块 HBM，MTP 的额外开销反而拖慢了速度。
-
Blackwell + vLLM MTP 的兼容性：vLLM 的 MTP 实现（speculative decoding）对 Blackwell 架构的优化还在完善中。5090 的 compute capability 是 10.0，vLLM 有些 kernel 还没有针对这个架构做专门调优。你在多卡时用的是 5080（compute 8.9）+ 3060（8.6），那些 kernel 反而更成熟。
-
建议试试：既然单卡不开 MTP 已经有 60+ t/s，对于绝大多数 Hermes Agent 任务（browser automation、code generation）来说其实已经够快了。可以先关掉
--enable-mtp参数，用纯 vLLM 跑一段时间看看体验。如果需要更高的并发吞吐（多人同时使用），再考虑 MTP 调优。
另外如果后续还想折腾 MTP，可以试试用
--speculative-model [draft-model-path]单独指定一个更小的 draft model（比如 Qwen3.6-0.5B），而不是用内置的 MTP head，这样兼容性和显存分配可能会更好。 -
-
5080 魔改下显存。华强北 欢迎您。如果改到32G 一切问题 迎刃而解。
