Underestimated budget solution: radeon 780m iGPU

There are so many posts where people complaining about high prices and asking for solution <= 1000 EUR. So, there is one solution to consider: PC/mini PC/laptop on Ryzen 7 260/Ryzen 9 8945HX/etc CPU with 780m iGPU and 64 Gb of DDR5 RAM. Barebone mini PC costs around 300-400, used 2x 32Gb DDR5 SO-DIMM around 500, used SSD 50-100 in my area. Here are my numbers on Ryzen 7 260, Ubuntu 26 with kernel params amdgpu.gttsize=49152 amd_iommu=off ttm.pages_limit=16777216 (48Gb of "VRAM") and llama.cpp with Vulkan. All LLMs are Unsloth Q8 quants.

For dense models it is mostly useless, I only could get Gemma4 31B running in draft-simple mode with drafter Gemma4 E2B on GPU, which gave like 5-6 => 6-7 tg boost. But for MoE you can use partial experts offloading which gives a greater boost for tg, but for a slower pp. Qwen 3.6 35B-A3B Q8 MTP (--spec-type draft-mtp --spec-draft-n-max 3 --n-cpu-moe 37): 14.22.441.606 I slot print_timing: id 0 | task 233 | prompt eval time = 28373.08 ms / 2677 tokens ( 10.60 ms per token, 94.35 tokens per second) 14.22.441.611 I slot print_timing: id 0 | task 233 | eval time = 9697.76 ms / 338 tokens ( 28.69 ms per token, 34.85 tokens per second) 14.22.441.611 I slot print_timing: id 0 | task 233 | total time = 38070.84 ms / 3015 tokens 14.22.441.612 I slot print_timing: id 0 | task 233 | graphs reused = 289 14.22.441.615 I slot print_timing: id 0 | task 233 | draft acceptance = 0.85614 ( 244 accepted / 285 generated), mean len = 3.57 I know number are not whopping, and you can't run DeepSeek on it. But is there a better solution for that money? submitted by /u/MaximusSenior [link] [comments]
