Medgemma 27B Text IT — Hardware Requirements & GPU Compatibility

Chat

Google MedGemma 27B Text IT is a 27-billion parameter instruction-tuned model specialized for the medical domain, built on the Gemma architecture by Google. It is fine-tuned on medical and clinical text data to provide improved performance on healthcare-related tasks such as medical question answering, clinical reasoning, and health information summarization. The model requires a GPU with at least 24GB of VRAM for quantized inference. Its domain specialization makes it notably more capable than general models on clinical benchmarks, though it should not be used as a substitute for professional medical advice. Released under the Gemma license.

Can NVIDIA GeForce RTX 5090 run Medgemma 27B Text IT?

No — Medgemma 27B Text IT requires at least 59.4 GB at BF16, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.

Can I run Medgemma 27B Text IT on a Mac?

Medgemma 27B Text IT requires at least 59.4 GB at BF16, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.

Can I run Medgemma 27B Text IT locally?

Yes — Medgemma 27B Text IT can run locally on consumer hardware. At BF16 quantization it needs 59.4 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Medgemma 27B Text IT?

At BF16, Medgemma 27B Text IT can reach ~81 tok/s on AMD Instinct MI350X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = (bandwidth GB/s ÷ model GB) × efficiency

Example: NVIDIA B200 → 8000 ÷ 59.4 × 0.65 = ~88 tok/s
