Is this performance normal for qwen3 8b with llama.cpp?

[markussiebert]

I have a question regarding the performance of the Qwen3 model (specifically the 8B q8k_xl variant) when running on an A770 GPU.

Current Observations:

Memory Bandwidth (IMC):
IMC Read: 25,000 MiB/s
IMC Write: 50 MiB/s
Compute Utilization: Approximately 30%
CPU Core Usage: 10 out of 12 cores are at 100% utilization.

The inference speed is really slow, about 8 tokens/second. Is this an expected result?

The deepseek 0528 Model nearly uses 100% compute and only one core.

Hi @markussiebert , it looks like not an expected result.
On our A770 machine, with https://github.com/ipex-llm/ipex-llm/releases/download/v2.3.0-nightly/llama-cpp-ipex-llm-2.3.0b20250612-ubuntu-core.tgz, for DeepSeek-R1-0528-Qwen3-8B-UD-Q8_K_XL.gguf I can get about 30 tokens/second for decode stage.
My test command is:

export ONEAPI_DEVICE_SELECTOR=level_zero:0
export SYCL_PI_LEVEL_ZERO_USE_IMMEDIATE_COMMANDLISTS=1
./llama-cli -m  /mnt/disk1/models/DeepSeek-R1-0528-Qwen3-8B-UD-Q8_K_XL.gguf -t 8 -ngl 99 -c 1024

Would you mind having a double check about it ? Btw I see there is only one CPU core used.

Hi @rnwang04 thanks for your answer.

For the DeepSeek qwen 3 model, I get about 21 t/s - maybe because your test machine has better CPU?

Hi @markussiebert ,

performance on my machine

My test machine is i9-13900K + A770, and I tested with this portable zip https://github.com/ipex-llm/ipex-llm/releases/download/v2.3.0-nightly/llama-cpp-ipex-llm-2.3.0b20250612-ubuntu-core.tgz .
On this machine, I got about 30.9 tokens/s for DeepSeek-R1-0528-Qwen3-8B-UD-Q8_K_XL.gguf, 14.64 tokens/s for Qwen3-8B-UD-Q8_K_XL.gguf, and 56.84 tokens/s for Qwen3-8B-Q4_K_M.gguf.

performance gap between two Q8_K_XL.gguf

Based on the output log, I found Qwen3-8B-UD-Q8_K_XL.gguf has bf16 tensor while DeepSeek-R1-0528-Qwen3-8B-UD-Q8_K_XL.gguf has fp16 tensor. I guess this performance gap is caused by we do not have good support for bf16 tensors.
I may take a further look about this later, if there is any update, will update here to let you know.

# DeepSeek-R1-0528-Qwen3-8B-UD-Q8_K_XL.gguf
llama_model_loader: - type  f32:  145 tensors
llama_model_loader: - type  f16:   63 tensors
llama_model_loader: - type q8_0:  191 tensors
# Qwen3-8B-UD-Q8_K_XL.gguf
llama_model_loader: - type  f32:  145 tensors
llama_model_loader: - type q8_0:  191 tensors
llama_model_loader: - type bf16:   63 tensors

But if you do not have very specific precision limitation, I would recommend you to try Q4_K_M version, it would provide better performance.

performance gap between our tests

Hmm actually I not very sure about this, just provide some possible reasons here:

• CPU difference
• Test with different input / output length: I just tested with short input / output, but I see your output is 1565 tokens
• What is your version of llama.cpp ?

[markussiebert]

I run

llama-cpp-ipex-llm-2.3.0b20250612-ubuntu-core

so the same version you are using. My cpu is way older than yours - it might make a difference.
