1st promptCold start — includes initialization
>Solve: If a train travels at 60 mph for 2.5 hours, how far does it go?
Let me work through this step by step.
Given information:
- Speed = 60 mph (miles per hour)
- Time = 2.5 hours
Formula: Distance = Speed x Time
Calculation:
Distance = 60 mph x 2.5 h
= 150 miles
The train travels 150 miles.
Double-check: at 60 mph the train covers 60 miles each hour. In half an hour it covers 30 miles. So in 2.5 hours: 60 + 60 + 30 = 150 miles. Confirmed.
2nd promptWarm — model ready, no init overhead
>What if the train stops for 20 minutes halfway?
The stop doesn't change the total distance covered while moving, but it affects total trip time.
Breakdown:
- First half: 1.25 hours at 60 mph = 75 miles
- Stop: 20 minutes (no distance)
- Second half: 1.25 hours at 60 mph = 75 miles
Total distance: 150 miles (same)
Total time: 2.5 h + 0.33 h = 2.83 hours
Average speed: 150 / 2.83 = 53 mph
The distance stays the same but average speed drops to 53 mph because of the stop.
Estimated: 45.7 tok/s decode · 4.2s TTFT (warm) · 114 tok/s prefill
What limits this setup
This setup is broadly balanced for this model.
Shared-memory contention still exists
The OS, browser, and inference runtime all compete for the same physical memory pool, so real-world headroom is less forgiving than raw capacity suggests.

Frequently asked questions
Can MacBook Pro M2 Pro 32GB run Gemma 3 4B?
Yes, MacBook Pro M2 Pro 32GB can run Gemma 3 4B with a B grade (Runs well). Expected decode speed: 45.7 tok/s.
How much VRAM does Gemma 3 4B need?
Gemma 3 4B (4B parameters) requires approximately 8.9 GB of memory with Q4_K_M quantization.
What is the best quantization for Gemma 3 4B?
The recommended quantization for Gemma 3 4B is Q4_K_M, which balances quality and memory efficiency.
What speed will Gemma 3 4B run at on MacBook Pro M2 Pro 32GB?
On MacBook Pro M2 Pro 32GB, Gemma 3 4B achieves approximately 45.7 tokens per second decode speed with a time-to-first-token of 4240ms using Q4_K_M quantization.
Can MacBook Pro M2 Pro 32GB run Gemma 3 4B for coding?
For coding workloads, Gemma 3 4B on MacBook Pro M2 Pro 32GB receives a B grade with 45.7 tok/s and 125K context.
What context window can Gemma 3 4B use on MacBook Pro M2 Pro 32GB?
On MacBook Pro M2 Pro 32GB, Gemma 3 4B can safely use up to 125K tokens of context. The model's official context limit is 128K, but available memory constrains the safe maximum.
Is unified memory on MacBook Pro M2 Pro 32GB as fast as VRAM for Gemma 3 4B?
Not always. MacBook Pro M2 Pro 32GB can often fit larger models thanks to unified memory, but a discrete GPU with dedicated high-bandwidth VRAM may still decode faster once the model fits. For this combination, the important distinction is capacity versus sustained throughput.
