Lenovo ThinkPad E14 (Budget Setup)

Scored against every model in our directory at Q4_K_M, using the ~4.8GB of GPU-usable memory on this machine and its 51.2 GB/s of memory bandwidth. Of 30 models, 1 runs comfortably, 0 are a tight fit, and 29 will not load. The largest model that fits well here is Meta Llama 3.2 3B Instruct.

How these are estimated: tokens/sec ≈ memory bandwidth × 0.65 ÷ active weights in GB. These are arithmetic estimates from published specifications, not lab measurements — BFWR does not run a hardware test lab. Real throughput varies with runner, quantization, context length and thermals.

Diffusion models size up differently from language models: the text encoder is often as large as the image model itself, and memory scales with resolution. Measured at 1024×1024, one image at a time, against the ~4.8GB of GPU-usable memory here, 3 of 11 open image models will run — the best being Stable Diffusion 1.5 at BF16 / FP16, peaking near 4.2GB.

Weight sizes are read from the real .safetensors files in each model’s Hugging Face repository. Activation memory is an approximation that varies with the attention implementation and sampler, so leave headroom. These are planning figures, not benchmarks.

What is the largest model the Lenovo ThinkPad E14 (Budget Setup) can run?

Meta Llama 3.2 3B Instruct (3.21B) is the largest model that fits, at roughly 2GB in Q4_K_M against ~4.8GB of GPU-usable memory. It is rated "Comfortable" here, with an estimated 16.6 tokens/sec.

How many tokens per second should I expect?

Speed depends on the model, not just the machine. On this hardware the estimates range from about 16.6 tokens/sec for the smallest models down to single digits for the largest that still fit. The estimate uses memory bandwidth (51.2 GB/s here) × 0.65 ÷ active weights in GB, and is not a measured benchmark.

Can the Lenovo ThinkPad E14 (Budget Setup) run a 70B model?

Not in a usable way. A 70B model needs roughly 40GB+ at Q4_K_M before context, which exceeds the ~4.8GB of GPU-usable memory available here. A mixture-of-experts model is usually the better route on this machine, since only a fraction of its weights are active per token.

How much context can I use?

8k tokens is a sensible ceiling on this machine at Incompatible (Requires 16GB+). Context is stored in the KV cache, which grows with every token and competes with the model weights for the same memory, so a longer context means a smaller model.

Can the Lenovo ThinkPad E14 (Budget Setup) generate images with Flux or Stable Diffusion?

Yes. 3 of 11 open image models fit at 1024x1024, the best being Stable Diffusion 1.5 at BF16 / FP16, peaking near 4.2GB. Higher resolutions and larger batches cost proportionally more.

Which runner works best on the Lenovo ThinkPad E14 (Budget Setup)?

Ollama are all expected to run on this hardware. Ollama is the simplest starting point, and `ollama run gemma4:e4b` is a good first model for this machine.
