What is a DMA Card?

1. Introduction to DMA Card Applications

A DMA card, also known as a DMA board, is essentially a DMA FPGA development board that enables Direct Memory Access (DMA), allowing hardware components to transfer data between memory and peripherals without involving the CPU. This significantly enhances data transfer efficiency.

DMA cards have a wide range of applications across various fields, including medical equipment, industrial automation, and communication systems. One of the most well-known applications is DMA cheating in gaming, where DMA cards are utilized to extract and process real-time game data with high efficiency. However, it is important to note that a DMA card itself is merely a development board—its functionalities depend entirely on software development.

2. Technical Specifications and Market Overview

Currently, Xilinx FPGA chips dominate the DMA card market, with mainstream models including 35T, 75T, and 100T. These models differ primarily in their logic units (LUTs), memory capacity, and processing power.

  • 35T DMA Card – Entry-level model suitable for fundamental FPGA development.
  • 75T DMA Card – A balanced option with higher logic resources, commonly used in advanced applications.
  • 100T DMA Card – The next-generation standard, offering superior DMA performance for high-speed data applications.

Leading DMA Card Brands

Several brands specialize in manufacturing DMA development boards, with the most notable being:

  • CaptainDMA – The most popular brand, especially its 75T model, which is widely used among gaming enthusiasts.
  • StarkDMA – Known for high-speed PCIe interfaces and compatibility with multiple platforms.
  • HackDMA – Focuses on low-latency data processing and security applications.
  • LeetDMA – Offers DMA boards optimized for gaming and AI-driven automation.
  • MVP DMA – Recognized for its robust hardware reliability.

With 100T DMA cards gaining traction in 2025, the industry is shifting towards more powerful, high-speed solutions. However, while the hardware is readily available, firmware development for various applications is still ongoing.

3. Core Advantages of DMA Cards

DMA cards provide distinct advantages in high-speed data transfer and customizable functionality:

  • Bypassing Software Detection – Since DMA operates outside the OS, it evades traditional anti-cheat software like BattlEye and Easy Anti-Cheat (EAC).
  • Real-Time Data Processing – Direct PCIe memory access ensures ultra-fast data extraction and transmission.
  • Programmability – Unlike fixed-function hardware, FPGA-based DMA cards allow software-driven customization, giving developers maximum flexibility in application design.
  • High-Speed Interface Support – With PCIe, USB-C, and HDMI/DP compatibility, these cards seamlessly integrate with modern computing platforms.
