LOCAL LLM Compatibility Evaluation

This quick guide shows what types of large language models (LLMs) each of these laptops could support, based on their respective hardware specifications. It's meant to help you compare their suitability for running AI models locally.

LLM Category	Samsung Galaxy Book 2 Pro (15.6”)	Dell Alienware m15 R4

GPU	Intel Iris Xe Graphics (80EU)	GeForce RTX 3060 Mobile 6GB
Memory	16 GB	16 GB ; 6 GB VRAM
Available for LLM total	~10.5 GB (10.5 GB RAM)	~17.3 GB (4.5 GB VRAM 12.8 GB RAM)
Small Models (1-3B): Examples: Phi-2, Qwen-1.8B Requires ~2 GB memory	✔ Modest Speed fits in your 10.5 GB RAM	✔ Runs Smoothly fits in your 6 GB VRAM
Medium Models (7-8B): Examples: Mistral-7B, Qwen-7B Requires ~5 GB memory	⚠ Borderline / Slow fits in your 10.5 GB RAM	✔ Modest Speed doesn't fit in 6 GB VRAM, spills to RAM (VRAM + RAM, slower)
Large Models
13-15B Models (e.g., Llama 3 14B, Qwen1.5 14B) Requires ~9 GB memory	! Not Practical fits in your 10.5 GB RAM	⚠ Borderline / Slow doesn't fit in 6 GB VRAM, spills to RAM (VRAM + RAM, slower)

Samsung Galaxy Book 2 Pro (15.6”)|Dell Alienware m15 R4

Note: Optimized (e.g., 4-bit) models may run on limited hardware. Performance depends on runtime and setup.

📌 Model Types: Dense 30B Q4 models typically require around 19–22 GB of total VRAM, so they run best on systems with ≥24 GB VRAM. MoE models like Mixtral 8x7B (≈47B total parameters, usually ≈23–26 GB in 4-bit) also need high memory because all experts must be loaded, even though only a few are active per token. They reduce compute cost per token (similar to a ~12–13B dense model), but not memory usage, so they are not practical on 14–16 GB systems.

🚀 Modern NPU (Neural Processing Unit): Modern processors like AMD Ryzen AI and Intel Core Ultra feature NPU and unified memory architecture. NPUs provide modest performance gains (0-30% faster) with better power efficiency compared to iGPU-only execution. Real-world tests show ~3-10 tok/s range on 13B models with 32GB RAM (varies by runtime, quantization, and context), comparable to iGPU but more power-efficient. Note: These figures are examples from various NPU systems; actual performance depends on your specific hardware configuration.

Understanding Performance Categories

The performance descriptions use general categories because actual speed varies greatly based on your specific hardware, model optimization, context length, and runtime software.

Performance Level	Typical Range	User Experience
Runs Smoothly (High-end dGPU)	50+ tok/s	Real-time response. Feels instant, like ChatGPT.
Runs Well (Mid-range dGPU)	20-50 tok/s	Good interactive performance. Slight delay, but usable.
Modest Speed (iGPU/NPU/CPU)	5-20 tok/s	Usable for tasks that don't need instant responses. Noticeable typing delay.
Borderline / Slow (Limited hardware)	2-5 tok/s	Slow-Very slow. Patience required. Better for batch processing.
Not Practical	<2 tok/s	Too slow for regular use. May cause system hangs or instability.

💡 Tip: Your actual results may be higher or lower than these ranges. Test with your specific hardware to know for sure!

⚠️ Note: Performance categorization is based on VRAM capacity and RAM fallback status. GPU type (memory bandwidth, compute power) can also affect actual performance. Currently, we prioritize whether the model fits in VRAM or requires RAM fallback for classification. We may refine this categorization in future updates based on more detailed benchmarks.

If your budget allows, we recommend opting for the largest possible disk size, considering the potential increase in storage capacity needs in the future. However, please keep in mind the question 'What will the laptop be used for?' when making this decision. Of course, you can later upgrade the hard disk capacity by getting a larger disk. However, if your laptop has only one disk slot, it may not be as straightforward as a RAM upgrade, where you simply add or replace a module, as moving or cloning files to a new disk may be necessary.
