AMD Radeon HD 8770 OEM: An Overview of an Obsolete GPU in 2025

April 2025

Introduction

The AMD Radeon HD 8770 OEM is a graphics card released in the early 2010s for the OEM segment (pre-built PCs and workstations). Despite its age, it is still found in older systems. In 2025, its relevance is nearing zero, but it may still be useful for certain tasks. Let’s explore who might benefit from this GPU today.

1. Architecture and Key Features

Architecture: The HD 8770 OEM is based on the GCN 1.0 (Graphics Core Next) architecture, which was the first iteration of AMD's revolutionary design.

Manufacturing Process: 28 nm, which is typical for the 2012-2014 era.

Unique Features:

- Support for Mantle API (a predecessor to Vulkan), which improved performance in games of that time.

- AMD Eyefinity technology for connecting multiple monitors.

- Lack of modern features: ray tracing, FidelityFX Super Resolution, or DLSS equivalents are not available.

Conclusion: The card was designed as a budget solution for office tasks and basic multimedia, but today its capabilities are severely limited.

2. Memory

Memory Type: GDDR5.

Capacity: 2 GB — a minimal amount even for games from 2015.

Bus and Bandwidth: 128-bit bus with a bandwidth of up to 72 GB/s.

Impact on Performance:

- Small capacity and low bandwidth become a "bottleneck" in modern applications.

- Even web browsers with heavy pages (e.g., streaming 4K video) can cause stuttering.

3. Gaming Performance

1080p Resolution (Low Settings):

- CS:GO: 60-80 FPS (no anti-aliasing).

- GTA V: 25-35 FPS.

- Fortnite: 20-25 FPS (minimum settings).

1440p and 4K: Not recommended — the card cannot even handle rendering the interface.

Ray Tracing: Not supported natively.

Modern Titles (2023-2025):

- Cyberpunk 2077, Starfield — unable to launch, or FPS <10.

- Indie games (e.g., Hades) — 40-50 FPS on low settings.

Recommendation: Only suitable for older projects or cloud gaming through services like Xbox Cloud.

4. Professional Tasks

Video Editing:

- Working in DaVinci Resolve or Premiere Pro is only feasible with proxy files. Rendering 1080p video will take 3-5 times longer than on modern GPUs.

3D Modeling:

- Blender and Maya — only for simple scenes. Rendering on OpenCL is slow (30-60 minutes for a medium complexity scene).

Scientific Calculations:

- OpenCL 1.2 support is available, but performance is 10-15 times lower than modern Radeon RX 7000 or NVIDIA RTX 4000 series.

Conclusion: The card is outdated for professional tasks. It is suitable only for learning or emergency cases.

5. Power Consumption and Heat Dissipation

TDP: 75 W — powered through the PCIe slot without needing an additional connector.

Cooling: Passive or basic cooler. Even under load, temperatures rarely exceed 70°C.

Case Recommendations:

- Any case with basic ventilation is suitable.

- A power supply of 300 W (e.g., EVGA 300 BR) is sufficient for a build with the HD 8770 OEM.

Pros: Low power consumption makes the card quiet and economical.

6. Comparison with Competitors

Analogues from 2013-2015:

- NVIDIA GeForce GT 740: Comparable in performance but poorly optimized for OpenCL.

- Intel HD Graphics 4600 (integrated): In 2025, the integrated graphics of new processors (e.g., Ryzen 5 8600G) outpace the HD 8770 OEM by 2-3 times.

Modern Budget GPUs (2025):

- AMD Radeon RX 7400: 300% faster, priced at $150.

- Intel Arc A310: Supports Ray Tracing and XeSS, priced at $130.

Conclusion: The HD 8770 OEM is outclassed even by the cheapest new GPUs.

7. Practical Tips

Power Supply: 300 W is sufficient. Examples: Corsair CV450, be quiet! System Power 10.

Compatibility:

- PCIe 3.0 x16 (backward compatible with 2.0).

- OS Support: Official drivers are available only up to Windows 10. Windows 11 may have issues.

Drivers: Use the latest version from AMD's site (released in 2020). The open-source driver amdgpu will work for Linux.

Important: Do not purchase this card separately — only consider it if it is already in your PC.

8. Pros and Cons

Pros:

- Quiet operation.

- Low power consumption.

- Supports 3 monitors via DisplayPort and HDMI.

Cons:

- Weak performance in 2025.

- No support for modern APIs (DirectX 12 Ultimate, Vulkan 1.3).

- Limited driver support.

9. Final Verdict: Who is the HD 8770 OEM For?

- Owners of old PCs: For upgrading systems with GPUs from the 2000s.

- Office Tasks: Document work, video playback, video calls.

- Retro Hardware Enthusiasts: For building a PC in the style of the 2010s.

Alternative: If your budget is limited to $100-$150, consider new integrated graphics (Ryzen 5 8600G) or a used GTX 1650.

Summary: The HD 8770 OEM in 2025 is a relic. It should be considered only as a temporary solution or part of a nostalgic project. For any serious tasks, a more modern GPU is required.

TMUs

Texture Mapping Units (TMUs) serve as components of the GPU, which are capable of rotating, scaling, and distorting binary images, and then placing them as textures onto any plane of a given 3D model. This process is called texture mapping.

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.

Pixel Rate

Pixel fill rate refers to the number of pixels a graphics processing unit (GPU) can render per second, measured in MPixels/s (million pixels per second) or GPixels/s (billion pixels per second). It is the most commonly used metric to evaluate the pixel processing performance of a graphics card.

16.80 GPixel/s

Texture Rate

Texture fill rate refers to the number of texture map elements (texels) that a GPU can map to pixels in a single second.

FP64 (double)

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.

FP32 (float)

An important metric for measuring GPU performance is floating-point computing capability. Single-precision floating-point numbers (32-bit) are used for common multimedia and graphics processing tasks, while double-precision floating-point numbers (64-bit) are required for scientific computing that demands a wide numeric range and high accuracy.

ROPs

The Raster Operations Pipeline (ROPs) is primarily responsible for handling lighting and reflection calculations in games, as well as managing effects like anti-aliasing (AA), high resolution, smoke, and fire. The more demanding the anti-aliasing and lighting effects in a game, the higher the performance requirements for the ROPs; otherwise, it may result in a sharp drop in frame rate.
