What to Look for in a GPU for Ollama
VRAM Capacity
VRAM is the single most important spec when choosing a GPU for Ollama. Models load entirely into GPU memory, and if your card does not have enough, inference falls back to system RAM or simply refuses to run at full speed. A 7B model in full precision needs around 14GB, while quantized versions can squeeze into 8GB.
Cards like the ASUS TUF Gaming GeForce RTX™ 5080 16GB GDDR7 OC and the GIGABYTE GeForce RTX 5080 Gaming OC 16G Graphics both pack 16GB of GDDR7, giving you enough headroom to comfortably run 13B models in Q4 or Q5 quantization with tokens to spare.
Memory Bandwidth
Raw VRAM capacity tells only half the story. Memory bandwidth determines how quickly the GPU can feed data to its compute cores during inference, and this directly sets your tokens-per-second ceiling. GDDR7 memory, found on the latest Blackwell and RDNA 4 cards, delivers substantially higher bandwidth than older GDDR6X designs.
The GIGABYTE Radeon RX 9070 XT Gaming OC 16G Graphics runs on AMD’s RDNA 4 architecture with GDDR6 and PCIe 5.0, offering a compelling balance of bandwidth and capacity for the asking price. It is a strong choice if you prefer the AMD ecosystem or want ROCm compatibility for certain inference frameworks.
Architecture and AI Acceleration
Not all GPU compute is equal for AI workloads. NVIDIA’s Blackwell architecture introduces fourth-generation Tensor Cores alongside DLSS 4, and those Tensor Cores handle the matrix multiplications that dominate LLM inference. Cards like the ASUS TUF Gaming GeForce RTX 5070 12GB GDDR7 OC and the GIGABYTE GeForce RTX 5070 Ti Gaming OC 16G benefit directly from this hardware acceleration.
CUDA support also matters here. Ollama’s default backend is optimized for CUDA, which means NVIDIA cards typically deliver better out-of-the-box performance with zero extra configuration compared to AMD alternatives, though ROCm support has improved considerably in recent releases.
Budget vs. Capability Tradeoffs
Not every Ollama user needs a flagship card. The HP NVIDIA Tesla M60 16GB Server GPU Accelerator is a renewed enterprise card that packs 16GB of VRAM at a fraction of the cost of a new consumer GPU. It lacks modern AI acceleration features, but for users who primarily need raw VRAM to load larger models and are not chasing maximum tokens per second, it is a pragmatic option worth evaluating.
Keep in mind that server-class cards like the Tesla M60 are passively cooled and were designed for rack-mounted environments, so you will need adequate case airflow. Pairing this with a solid understanding of your hardware budget, similar to how RC enthusiasts weigh options in our RC and Drones section, helps you avoid overspending on specs you will not use.
Final Thoughts
For most users running Ollama at home, the sweet spot sits between a capable mid-range card and a true flagship, depending on which model sizes you want to run comfortably. If you want the best overall balance of VRAM, modern AI acceleration, and energy efficiency, the ASUS TUF Gaming GeForce RTX 5070 12GB GDDR7 OC is a well-rounded pick for 7B and many 13B models, while power users who need to run larger models without quantization compromises will find the ASUS TUF Gaming GeForce RTX™ 5080 16GB GDDR7 OC worth the investment for its headroom and raw throughput.
Frequently Asked Questions
How much VRAM do I need to run Ollama?
It depends on the model size and quantization level you plan to use. For most 7B models in Q4 quantization, 8GB of VRAM is sufficient, but 12GB to 16GB gives you much more flexibility. If you want to run 13B or 30B models without heavy quantization, aim for at least 16GB.
Can I use an AMD GPU with Ollama?
Yes, Ollama supports AMD GPUs through ROCm on Linux. The GIGABYTE Radeon RX 9070 XT Gaming OC 16G Graphics is a capable modern AMD option with 16GB of memory. Windows ROCm support is more limited, so Linux is recommended if you go the AMD route for AI inference in 2026.
Is a refurbished server GPU a good choice for running local LLMs?
A renewed enterprise card can be a cost-effective way to get a large VRAM pool without a high upfront cost. The tradeoff is that older server GPUs lack modern Tensor Core acceleration, which means your tokens-per-second rate will be lower than a current-generation consumer card with the same VRAM amount. For casual or low-latency-tolerant use cases, it can still be a practical option worth considering.
Does the GPU matter more than the CPU for Ollama performance?
When a model fits entirely in VRAM, the GPU dominates performance and the CPU becomes largely a bystander. The CPU only becomes a bottleneck when models overflow into system RAM and Ollama falls back to CPU inference, which is dramatically slower. Prioritizing GPU VRAM over CPU specs is the right call for a dedicated Ollama workstation in 2026. For more context on balancing component choices across different electronics builds, the Graphics Cards category has additional guidance.
