llama.cpp Setup
Install the oneAPI Base Toolkit: https://www.intel.com/content/www/us/en/developer/tools/oneapi/base-toolkit-download.html
- I use Arch Linux on most of my dev systems, and the AUR is out of date, so you should download directly, install (it won’t deal with any dependencies so you will need to make sure you have them installed yourself) - it installs into
~/intel/oneapi
To use SYCL/IPEX-LLM, etc, you will need to load env vars, eg:
source ~/intel/oneapi/setvars.sh
- Requires a POSIX compatible shell to run (eg, fish won’t work)
If you have multiple oneAPI Base Toolkit versions installed (IPEX-LLM for example requires 2024.2.1, which is not the latest version):
source ~/intel/oneapi/2024.2/oneapi-vars.sh
Testing llama.cpp with Intel’s Xe2 iGPU (Core Ultra 7 258V w/ Arc Graphics 140V)
I have a Lunar Lake laptop (see my in-progress Linux review) and recently sat down and did some testing on how llama.cpp works with it.
- Chips and Cheese has the most in-depth analysis of the iGPU which includes architectural and real world comparisons w/ the prior-gen Xe-LPG, as well as RDNA 3.5 (in the AMD Ryzen AI 9 HX 370 w/ Radeon 890M).
- The 258V has 32GB of LPDDR5-8533, which has a theoretical maximum memory bandwidth of 136.5 GB/s. Chips and Chesee did some preliminary MBW testing and found actual throughput to be around 80 GB/s (lower than Strix Point), but MBW test is hard…
- The 140V Xe2 GPU on the 258V has Vector Engines with 2048-bit XMX units that Intel specs at 64 INT8 TOPS. Each XMX can do INT8 4096 OPS/clock or FP16 2048 OPS/clock, so that would be a max theoretical 32 FP16 TOPS.
For my testing, I use Llama 2 7B (specifically the q4_0 quant from [TheBloke/Llama-2-7B-GGUF]) as my standard benchmark (it is well quantified and has max compatibility). All testing was done with very-up-to-date HEAD compiles (build: ba6f62eb (4008)) of llama.cpp. The system itself is running CachyOS, a performance focused Arch Linux derivative, and it is running the latest 6.12 kernel 6.12.0-rc5-1-mainline and linux-firmware-git and mesa-git for the maximum support for Lunar Lake/Xe2.
My system is running at PL 28W (BIOS: performance), with the performance governor, EPP, and EPB.
It turns out there are quite a few ways to run llama.cpp - I skipped the NPU since it’s a PITA to setup, but maybe I’ll get bored sometime. Here’s my results:
| Backend | pp512 t/s | tg128 t/s | t/TFLOP | MBW % |
|---|---|---|---|---|
| CPU | 25.05 | 11.59 | 52.74 | 30.23 |
| Vulkan | 44.65 | 5.54 | 1.40 | 14.45 |
| SYCL FP32 | 180.77 | 14.39 | 5.65 | 37.53 |
| SYCL FP16 | 526.38 | 13.51 | 16.45 | 35.23 |
| IPEX-LLM | 708.15 | 24.35 | 22.13 | 63.51 |
- pp is prompt processing (also known as prefill, or input) - this is the speed at which any system prompt, context, previous conversation turns, etc are passed in and is compute bound
- tg is token generation (aka output) - this is the speed at which new tokens are generated and is generally memory bandwidth bound
- I’ve included a “t/TFLOP” compute efficiency metric for each Backend and also a MBW % which just calculates the percentage of the tg vs the theoretical max tg (136.5 GB/s / 3.56GB model size)
- The CPU backend doesn’t have native FP16. TFLOPS is calculated based on the maximum FP32 that AVX2 provides for the 4 P-Cores (486.4 GFLOPS) at 3.8GHz (my actual all-core max clock). For those interested on llama.cpp’s CPU optimizations, I recommend reading jart’s writeup LLaMA Now Goes Faster on CPUs
- For CPU, I use
-t 4, which uses all 4 of the (non-hyperthreaded) P-cores, which is the most efficient setting. This basically doesn’t matter for the rest of the GPU methods.
For SYCL and IPEX-LLM you will need to install the Intel oneAPI Base Toolkit. I used version 2025.0.0 for SYCL, but IPEX-LLM’s llama.cpp requires 2024.2.1
- Setup docs to Run llama.cpp with IPEX-LLM on Intel GPU - as of testing, the llama.cpp was based off of a 2024-08-22 version
The IPEX-LLM results are much better than all the other Backends, but it’s worth noting that despite the docs suggesting otherwise, with the Xe2 Arc 140V GPU atm, it doesn’t seem to work with k-quants (related to this error?). Still, at 35% faster pp and 80% faster tg than SYCL FP16, it’s probably worth trying to use this if you can.
vs Apple M4
I haven’t seen any M4 inference numbers, yet, but this chart/discussion Performance of llama.cpp on Apple Silicon M-series #4167 is a good reference. The M3 Pro (18 CU) has 12.78 FP16 TFLOPS and at 341.67 t/s pp, that gives a ~26.73 t/TFLOP for Metal performance. The new M4 Pro (20 CU) has an expected 17.04 TFLOPS so at the same efficiency you’d expect ~455 t/s for pp. For MBW, we can again run similar back-calculations. The M3 Pro has 150 GB/s MBW and generates 30.74 t/s tg for a 73% MBW efficiency. at 273 GB/s of MBW, we’d expect the M4 Pro to have a ballpark tg of ~56 t/s.
vs AMD Ryzen AI
The Radeon 890M on the top-end Ryzen AI Strix Point chips have 16CUs and a theoretical 23.76 TFLOPS, and with LPDDR5-7500, 120GB/s of MBW. Recently AMD just published an article Accelerating Llama.cpp Performance in Consumer LLM Applications with AMD Ryzen™ AI 300 Series testing the performance of a Ryzen AI 9 HX 375 with a Intel Core Ultra 7 258V. It mostly focuses on CPU and they similarly note that llama.cpp’s Vulkan backend works awfully on the Intel side, so they claim to compare Mistral 7B 0.3 performance w/ IPEX-LLM, however they don’t publish any actual performance numbers, just a percentage difference!
Now, I don’t have a Strix Point chip, but I do have a 7940HS with a Radeon 780M (16.59 TFLOPS) and dual channel DDR-5600 (89.6 GB/s MBW) so I ran the same benchhmark on a Mistral 7B 0.3 (q4_0) and did do some ballpark estimates:
| Hardware | Backend | TFLOPS | MBW (GB/s) | pp512 t/s | tg128 t/s | t/TFLOP | MBW % |
|---|---|---|---|---|---|---|---|
| Arc 140V | IPEX-LLM | 32 | 136.5 | 656.5 | 22.98 | 20.52 | 64.48 |
| Radeon 780M | ROCm | 16.59 | 89.6 | 240.79 | 18.61 | 14.51 | 79.55 |
| Radeon 890M (est) | ROCm | 23.76 | 120 | 344.76 | 24.92 | 14.51 | 79.55 |
| Strix Halo (est) | ROCm | 59.40 | 256 | 861.89 | 53.17 | 14.51 | 79.55 |
I just applied the same efficiency from the 780M results onto the 890M specs to get a projected performance number.
Efficiency Numbers
The t/TFLOP and MBW % numbers were interesting enough that I figured I’
