Quick overview
Best GPU for local LLMs in India: how to compare VRAM tiers, power, warranty, and runtime support without chasing gaming benchmarks alone.
The best GPU for local LLMs is not universal. It is the card you can buy with enough VRAM for your model, stable drivers for your runtime, and a PSU and case that keep it cool in your room. Indian buyers also care about warranty service centers and realistic lead times on high-VRAM SKUs.
Quick answer
Match GPU memory size to your largest model at your chosen quant. Research 8 GB for entry 7B, 12 GB for 14B class, 16 GB for many 24B paths, 24 GB for 32B class, and 40 GB+ for 70B. Then verify stock, power connectors, and warranty.
How to compare cards fairly
1. VRAM capacity (primary) 2. Memory bandwidth (secondary for token speed) 3. Power draw and PSU requirement 4. Runtime support (Ollama, llama.cpp, LM Studio notes for your OS) 5. Physical size and case clearance 6. Warranty and RMA in India
Tier thinking, not model worship
Newer generation cards improve efficiency, but a previous-gen 24 GB card can beat a current-gen 12 GB card for LLMs because memory size wins loading constraints.
Used market caution
Test for artifacts, thermal paste age, and mining wear. Follow how to test a used graphics card before large peer-to-peer purchases.
Pair with the rest of the system
A top-tier GPU on a weak PSU or starved case becomes a throttling GPU. Include airflow planning from PSU and cooling for AI PCs.
How Roger N Reckon can help
Roger N Reckon can spec GPU options against your model list and check PSU and case compatibility during a workstation quote. Enquire via Workstation Builds.
Practical checklist
1. Write down the model size, quant level, and target context length you need. 2. Measure current GPU VRAM, system RAM, and free NVMe space before buying parts. 3. Confirm PSU wattage against the GPU vendor's required system power. 4. Plan cooling for sustained inference, not just short benchmarks. 5. Back up data before OS or hardware changes. 6. Request a written component list, testing scope, and warranty terms for any build or upgrade. 7. Re-test with the same prompt and context after changes.
Frequently Asked Questions
Is NVIDIA mandatory?
Not mandatory, but often the path of least friction on Windows. Verify your chosen engine supports AMD if you go Radeon.
Do professional RTX cards help?
Workstation cards can offer more VRAM and driver stability for some users, at higher cost. Consumer cards dominate home LLM builds.
Will dual GPUs double speed?
Rarely for single-user chat. Dual GPUs help specific multi-GPU inference setups; see dual GPU LLM guide.
Does India voltage affect GPU choice?
Use a quality PSU with appropriate efficiency rating; GPU model choice is about memory, not mains voltage.
Where do I read VRAM tables?
Start with how much VRAM and external references such as llamaperf.com.
Final takeaway
There is no single best GPU. There is a best fit for your model file and room conditions.
