What is an AI Server? 2025 Complete Guide | Architecture, Vendors, Investment Guide

Introduction: Why Have AI Servers Suddenly Become So Important?

How much computing power does it take to run ChatGPT?

The answer is: tens of thousands of GPUs running 24/7.

This is the value of AI servers. In 2024, the global AI server market exceeded $50 billion and is projected to reach $250 billion by 2028. As a global AI server manufacturing hub, Taiwan's related stocks are a focus for investors.

This article will help you fully understand: what AI servers are, how the hardware architecture is composed, which important vendors are in Taiwan, and what to consider when investing in AI server stocks.

If you're not familiar with servers in general, we recommend first reading Server Complete Guide: From Basics to Enterprise Applications

1. What is an AI Server?

1.1 AI Server Definition

An AI server is high-performance computing equipment specifically designed for artificial intelligence workloads.

The biggest difference from traditional servers is that the computing core of an AI server is a GPU (Graphics Processing Unit), not a CPU.

Why use GPUs?

Because AI model training requires massive "matrix operations." CPUs are generalists that can do everything but process only a small number of operations at once. GPUs are specialists that handle parallel computing and can execute thousands of computing tasks simultaneously.

Here's an analogy:

• A CPU is like a top mathematician—very precise, but solving one problem at a time
• A GPU is like a thousand average calculators—each solving simple problems, but all working simultaneously

AI training needs exactly the latter—massive simple operations performed simultaneously.

1.2 Differences Between AI Servers and Traditional Servers

Comparison	Traditional Server	AI Server
Computing Core	CPU (Intel Xeon, AMD EPYC)	GPU (NVIDIA H100, A100)
Memory Type	DDR4/DDR5	HBM (High Bandwidth Memory)
Memory Capacity	64GB - 1TB	80GB - 640GB (HBM)
Single Unit Power	500W - 1,500W	5,000W - 15,000W
Cooling Method	Air cooling	Liquid/water cooling
Network Bandwidth	10-100 Gbps	400-800 Gbps
Single Unit Price	$3,000 - $30,000	$15,000 - $1,500,000
Primary Use	Websites, databases, enterprise apps	AI training, inference, large language models

The most striking difference is power consumption. An AI server with 8 NVIDIA H100 GPUs can consume 10-15kW, equivalent to 10 traditional servers.

This is why cooling technology for AI servers is so critical. To learn more about different server types, see Server Types Complete Guide: 7 Common Server Types Compared.

1.3 The Core Role of GPU Servers

The GPU is the heart of an AI server.

Currently, NVIDIA dominates over 90% of the AI GPU market. Main product lines include:

GPU Model	Release Date	HBM Capacity	Computing Performance	Use Case
A100	2020	40/80GB	312 TFLOPS	Mid-size AI training
H100	2022	80GB	989 TFLOPS	Large language models
H200	2024	141GB	989 TFLOPS	Ultra-large model training
B200	2024	192GB	2,250 TFLOPS	Next-gen AI applications

The H100 is currently the mainstream AI training chip, with a single card priced at approximately $25,000-40,000.

A high-end AI server might have 8 H100 cards, with GPU costs alone exceeding $200,000.

2. AI Server Hardware Architecture

Understanding AI servers requires knowing their hardware components.

2.1 GPU: NVIDIA H100, H200, B200 Introduction

Key component explanations:

• GPU: 8 GPUs is the current mainstream configuration
• NVSwitch: NVIDIA proprietary technology enabling high-speed GPU-to-GPU communication
• CPU: Handles control and data preprocessing
• HBM: Each GPU has its own high-bandwidth memory
• InfiniBand: Connects multiple servers to form a cluster

2.3 High-Speed Network Interconnect: NVLink, InfiniBand

AI training requires multiple GPUs and servers working together—network speed determines overall performance.

NVLink (GPU Interconnect)

• NVIDIA proprietary technology
• NVLink 4.0 provides 900 GB/s unidirectional bandwidth
• Enables fast data exchange between GPUs in the same server

InfiniBand (Server Interconnect)

• Currently mainstream is 400 Gbps (NDR)
• Next-gen 800 Gbps (XDR) is being deployed
• Lower latency and higher bandwidth compared to traditional Ethernet

Why is networking so important?

Training GPT-4 class models requires thousands of GPUs computing simultaneously. If GPU-to-GPU communication is too slow, everyone waits for data, dramatically reducing efficiency.

2.4 Cooling and Power Requirements

One of the biggest challenges for AI servers is cooling.

A single H100 GPU has a TDP (Thermal Design Power) of 700W. An 8-GPU server generates 5,600W of heat from GPUs alone. Adding CPU, memory, and power conversion losses, total power consumption can reach 10-15kW.

Traditional air cooling is no longer sufficient, making liquid cooling standard:

Cooling Method	Cooling Capacity	Suitable Power	Cost
Air Cooling	Standard	< 3kW/rack	Low
Direct Liquid Cooling (DLC)	Excellent	3-30kW/rack	Medium
Immersion Cooling	Superior	> 30kW/rack	High

Inventec	2356	+10%	10%+	Steady growth

Cooling Stocks

AI server power surges directly benefit cooling vendors:

Company	Code	Main Products	AI Server Focus
Auras	3324	Heat pipes, vapor chambers	H100 cooling module supplier
AVC	3017	Cooling modules	GPU cooling solutions
Sunon	2421	Cooling fans	Liquid cooling system fans

Power Stocks

High-power servers need high-wattage power supplies:

4.4 Investment Risk Reminders

While AI stocks look promising, there are still risks:

Industry Risks

• NVIDIA order concentration: Taiwan vendors heavily depend on NVIDIA orders; if NVIDIA loses market share, they'll be affected
• Fast technology iteration: AI chips update every 1-2 years; vendors must keep up
• Overcapacity risk: If AI demand falls short of expectations, inventory pressure may occur

Individual Stock Risks

• Margin pressure: ODM margins are generally low (5-8%)
• Customer concentration: Some vendors' revenue is highly concentrated in a few customers
• Stock prices already reflect expectations: Some stocks already had large gains in 2024

Investment Recommendations

• Diversify: Don't bet heavily on a single stock
• Focus on margins: Choose vendors with technical barriers and higher margins
• Long-term hold: AI is a long-term trend; short-term volatility is inevitable

5. 2025 AI Server Trends

The AI server industry is evolving rapidly. Here are key trends for 2025.

5.1 Liquid Cooling Becomes Standard

Liquid cooling used to be a high-end option; now it's becoming standard equipment.

The reason is simple: air cooling is no longer sufficient.

Cooling Method	Power Handling	2024 Share	2027 Estimate
Air Cooling	< 500W/GPU	70%	30%
Direct Liquid Cooling	500-1000W/GPU	25%	55%
Immersion Cooling	> 1000W/GPU	5%	15%

NVIDIA GB200 single GPU power consumption reaches 1,200W—traditional air cooling simply cannot handle it. Therefore, liquid cooling vendors (Auras, AVC, Chenbro) will continue to benefit.

5.2 Edge AI Servers Emerge

Not all AI computing needs to happen in data centers.

Edge AI servers bring computing closer to endpoints, with advantages including:

• Reduced latency: Autonomous driving and industrial automation need real-time response
• Bandwidth savings: No need to send all data back to the cloud
• Privacy protection: Sensitive data stays local

Edge AI servers are typically smaller and lower power, suitable for factories, retail stores, hospitals, and similar scenarios.

5.3 AI Inference Demand Explodes

AI applications are divided into two phases:

• Training: Building models, requires lots of GPUs
• Inference: Using models, demand is even larger

The current market focus is on training, but inference demand is growing rapidly.

Why? Because every time you chat with ChatGPT or generate AI images, that's "inference" computing. As AI applications proliferate, inference demand will far exceed training.

This means:

• Increased demand for inference-specific GPUs (like NVIDIA L4, L40S)
• Expansion of small and medium AI server market
• Cloud AI service providers continue to expand infrastructure
