Discover the best GPU VPS for Ollama at GPUMart. Power your AI workloads with the RTX A4000 VPS, designed for optimal performance and efficiency.

Introduction to Ollama

Ollama is an open source project that is a powerful and user-friendly platform for running LLMs on local machines. It acts as a bridge between the complexity of LLM technology and the desire for accessible and customizable AI experiences.

Essentially, Ollama simplifies the process of downloading, installing, and interacting with various LLMs, enabling users to explore their capabilities without requiring extensive technical expertise or reliance on cloud-based platforms.

GPU Requirements for Ollama AI

1. VRAM (Video RAM): The amount of VRAM required depends on the size and complexity of the models being used. Here’s a general guide based on common LLMs:

Small Models (up to 7B parameters): Require approximately 8-12GB of VRAM.

Medium Models (8B to 14B parameters): Require around 12-16GB of VRAM.

Large Models (15B+ parameters): May require 20GB or more, with some very large models needing 48+GB of VRAM.

2. CUDA Cores: A higher number of CUDA cores helps in parallel processing, which speeds up training and inference tasks. For efficient performance, a GPU with at least 3,000 CUDA cores is recommended, although more cores are beneficial for larger models.

Performance Testing of Large Models

To evaluate the performance of GPUMart’s RTX A4000 plan, we tested four large language models on Ollama. These models vary in size and computational demands, providing a comprehensive view of the plan's capabilities.

1. Qwen2:7b

Size: 4.4GB

Prompt Evaluation Rate: 63.91 tokens/s

Ollama run Qwen2-7b model

The Qwen2:7b model, with a size of 4.4GB, performs efficiently on the RTX A4000, delivering a prompt evaluation rate of 63.91 tokens per second. This model showcases the plan's ability to handle medium-sized models with ease.

2. Llama3:8b

Size: 4.7GB

Prompt Eval Rate: 50.84 tokens/s

Ollama run llama3-8b model

The Llama3:8b, slightly larger at 4.7GB, achieves a higher prompt evaluation rate of 50.84 tokens per second. With CUDA usage at 60% and VRAM usage around 6GB, this model highlights the RTX A4000's capacity to support efficient computation and memory utilization.

3. Phi3:14b

Model Size: 7.9GB

Prompt Eval Rate: 49.12 tokens/s

Ollama run Phi3-14b model

For the larger Phi3:14b model, which is 7.9GB, the prompt evaluation rate drops to 49.12 tokens per second. Despite the increased computational load, the RTX A4000 manages CUDA utilization effectively at 66%, with VRAM usage reaching 10GB.

4. Mixtral:8x7b

Model Size: 26GB

Prompt Eval Rate: 5.93 tokens/s

Ollama run mixtral-8x7b model

The Mixtral:8x7b model, with a substantial size of 26GB, pushes the RTX A4000 to its limits. The prompt evaluation rate is significantly lower at 5.93 tokens per second. The dedicated GPU memory usage is 15GB, complemented by 14GB of shared GPU memory usage, demonstrating the A4000's capability to handle very large models, albeit with reduced performance.
