感谢楼主. 7900xtx 能跑,不错. 明天试试dsh. 今天dsh+v4pro花了100多, 肉疼(不过确实强, 长链自主调试FPGA, 综合+ila probe+烧写+测试+uart输出分析一条龙, 我基本可以不用管, 花token就行).

关于--parallel 2 的测试
软硬件环境：
cpu： AMD Ryzen 7 9700X
RAM：DDR5 64GB 6000
GPU：R9700 32G
OS： Ubuntu 24.04
软件 ： llama.cpp + vulkan结论：将并行设为1或者2，大部分情况下，性能变化属于正常波动，没有明显差别。
但是，即使有32G显存，有些任务还是会报以下错误：
26.48.401.777 E init_batch: failed to prepare attention ubatches
26.48.401.778 W decode: failed to find a memory slot for batch of size 16
26.48.401.779 W srv decode: failed to find free space in the KV cache, retrying with smaller batch size, off = 190, n_batch = 8, ret = 1
26.48.403.275 E init_batch: failed to prepare attention ubatches
26.48.403.277 W decode: failed to find a memory slot for batch of size 8
26.48.403.277 W srv decode: failed to find free space in the KV cache, retrying with smaller batch size, off = 190, n_batch = 4, ret = 1
虽然使用了 --cache-type-k/v q8_0 做 KV 量化来节省显存，但是 128K 的超长上下文，加上 --parallel 2，对 KV Cache 的要求依然极其恐怖。模型权重稳稳地占了 17GB。但当开启并发，且 Prompt 超长时，给 128K 上下文预留的 KV Cache 空间，在高峰期（特别是并发请求时）瞬间耗尽了，导致没有空位给下一个 Token 的生成。
好消息是，llama.cpp不能为KV Cache分配空间，并不会导致崩溃或任务中断（我没有碰到过），只会导致llama.cpp降级重试，严重的情况下会感觉明显卡顿而已，不用过于担心。
所以，用7900XTX的朋友，把并发设为1可能是更好的选择。 -

请问大佬测试过rocm么？我现在使用rocm搭配您的参数基本都是首 token 平均 5.8s · 36 tok/s的数据，想看看是个例还是都这么慢。

7900xtx 全开模式下功耗多少
@Stone-Wong 西风卖的公版显卡默认上限291w，跑满大概280w

我不懂， 我的 3090 24G 跑 q4km 的128K 上下文， 平均下来也就23tokens /s ， 为啥 xtx可以 50多
哦发现了， 我是跑一晚上， 楼主只跑了几分钟

@Stone-Wong 7500F 32G DDR5 1TB硬盘，7900XTX 满功率在492W。连续测试过3个小时功率就在480-492W
