ATI Radeon HD 4890: Nostalgia or Practicality in 2025?

An Analysis of a Legendary Graphics Card Through the Lens of Modernity


Introduction

In 2009, the ATI Radeon HD 4890 became a symbol of high performance for gamers and enthusiasts. However, 16 years later, its relevance raises questions. Let's explore whether this graphics card is worth attention in 2025, and who might find it useful.


1. Architecture and Key Features

RV790 Architecture

The HD 4890 is built on the RV790 architecture with a 55 nm manufacturing process—revolutionary for 2009, but today such standards seem archaic (modern GPUs use 5–7 nm). The chip contained 959 million transistors and 800 stream processors.

Unique Features

Unlike modern technologies (DLSS, RTX), the HD 4890 supported only DirectX 10.1 and OpenGL 3.3. Among its standout features were GDDR5 technology and enhanced tessellation, but ray tracing or AI upscaling were not options.

Conclusion: The HD 4890's architecture is a relic of the pre-parallel computing revolution. Its potential for modern tasks is extremely limited.


2. Memory

Type and Size

The graphics card came equipped with 1 GB GDDR5 on a 256-bit bus. For 2009, this was generous: the buffer allowed for comfortable gaming at a resolution of 1920×1080.

Bandwidth

The memory clocked in at 3900 MHz (effective), providing a bandwidth of 124.8 GB/s. In comparison, even a budget-friendly Radeon RX 6500 XT (2024) offers 224 GB/s thanks to GDDR6.

Impact on Performance

By 2025, 1 GB of memory is critically insufficient. Modern games (e.g., Cyberpunk 2077 or Starfield) require a minimum of 4–6 GB even at 1080p. The HD 4890 would suit indie projects or older games at best.


3. Performance in Games

Real FPS Examples (in 2009)

- Crysis (Very High, 1080p): 25–30 FPS;

- Left 4 Dead 2 (Ultra, 1080p): 60+ FPS;

- World of Warcraft (Ultra, 1080p): 45–50 FPS.

Modern Games (2025)

Even on low settings, the HD 4890 would struggle with GTA VI or The Elder Scrolls VI. In Fortnite (1080p, Low), expect 10–15 FPS due to memory limitations and outdated drivers.

Resolutions and Ray Tracing

The card does not support 4K or ray tracing. Its ceiling is 720p–1080p for games released up to 2012.


4. Professional Tasks

Video Editing and 3D Modeling

The HD 4890 supports OpenCL 1.0, but this is insufficient for modern applications (Blender, Adobe Premiere Pro). Rendering a simple 3D scene would take 10–20 times longer than on a budget Radeon RX 6400.

Scientific Calculations

The lack of CUDA support and modern APIs renders the card useless for machine learning or simulations.


5. Power Consumption and Heat Generation

TDP and PSU Requirements

The TDP of the HD 4890 is 190 W. A power supply of at least 500 W is recommended for systems with this card.

Cooling and Cases

The standard cooler is noisy (up to 45 dB under load). A case with good ventilation (at least 2 fans) is recommended, or upgrading to a modern AIO cooler (compatibility with mounts is questionable).


6. Comparison with Competitors

Contemporaries (2009–2010):

- NVIDIA GeForce GTX 285: Offers higher performance in DirectX 10, but at a higher price ($350 vs. $250 for HD 4890).

- AMD Radeon HD 5870: Direct successor with support for DirectX 11—30–40% faster.

In 2025:

Even budget cards like the NVIDIA GTX 1650 ($150) or AMD Radeon RX 6400 ($130) outperform the HD 4890 by 5–7 times in performance.


7. Practical Tips

Power Supply

Minimum 500 W with an 80+ Bronze certification. Examples: Corsair CX550M, EVGA 500 BQ.

Compatibility

- Interface: PCIe 2.0 x16 (compatible with PCIe 3.0/4.0 but with bandwidth limitations).

- Drivers: Official support has ended. Try enthusiast builds or Linux with open-source drivers.

Notes

- Does not support UEFI BIOS—booting on newer motherboards may have issues.

- Adapters (DVI → HDMI) will be needed for connecting to monitors via DisplayPort or HDMI 2.1.


8. Pros and Cons

Pros:

- Low secondary market price ($20–50);

- Suitable for retro gaming (Windows XP/Vista, DirectX 9–10);

- Easy thermal paste replacement extends lifespan.

Cons:

- Does not support DirectX 12 and modern APIs;

- High power consumption;

- Lack of drivers for Windows 11/12.


9. Final Conclusion: Who is the HD 4890 For?

This graphics card is suitable for:

1. Collectors and enthusiasts building retro PCs;

2. Owners of older systems needing a replacement for a burnt-out GPU;

3. Overclockers experimenting with clock speeds (the core easily reaches 1 GHz).

For gaming in 2025, video editing, or work with AI, the HD 4890 is not suitable. If your budget is limited to $100–150, it’s better to choose a new Radeon RX 6400 or a used GTX 1060—they will offer significantly more capabilities.


Conclusion

The ATI Radeon HD 4890 is an important part of GPU history, but in 2025, its role is niche. It serves as a reminder of how far the industry has come, helping to appreciate modern technologies.

Memory Bus
?
The memory bus width refers to the number of bits of data that the video memory can transfer within a single clock cycle. The larger the bus width, the greater the amount of data that can be transmitted instantaneously, making it one of the crucial parameters of video memory. The memory bandwidth is calculated as: Memory Bandwidth = Memory Frequency x Memory Bus Width / 8. Therefore, when the memory frequencies are similar, the memory bus width will determine the size of the memory bandwidth.

Bandwidth

Memory bandwidth refers to the data transfer rate between the graphics chip and the video memory. It is measured in bytes per second, and the formula to calculate it is: memory bandwidth = working frequency × memory bus width / 8 bits.

An important metric for measuring GPU performance is floating-point computing capability. Double-precision floating-point numbers (64-bit) are required for scientific computing that demands a wide numeric range and high accuracy, while single-precision floating-point numbers (32-bit) are used for common multimedia and graphics processing tasks. Half-precision floating-point numbers (16-bit) are used for applications like machine learning, where lower precision is acceptable.
