About AMD Radeon HD 6670

The AMD Radeon HD 6670, launched on April 19, 2011, at a competitive price of $99 USD, represents AMD's TeraScale 2 architecture crafted on a 40 nm process. This graphics card features 1024 MB of GDDR5 VRAM and connects via PCIe 2.0 x16 interface, making it suitable for budget builds of its era. With a low TDP of 66W, the AMD Radeon HD 6670 offers efficient power consumption for systems without high-end cooling. It delivers solid performance in OpenCL workloads, scoring 1,894 points in Geekbench. The card's memory bandwidth supports decent throughput for 720p and entry-level 1080p gaming. Overall, it targets users seeking reliable mid-range graphics without excessive heat output.

In gaming, the Radeon HD 6670 from AMD handles resolutions up to 1080p at low to medium settings for titles from its time. Frame rates typically range from 30-60 FPS in games like Battlefield 3 or Skyrim at 720p. However, it lacks support for modern ray tracing or technologies like DLSS and FSR, limiting it to rasterization-based rendering. The 1GB VRAM capacity proves adequate for older games but bottlenecks in texture-heavy modern ports. Memory bandwidth from GDDR5 ensures smooth performance in DirectX 11 environments. Benchmark data confirms its capability for casual gaming without demanding ultra settings.

Cooling for the AMD's HD 6670 remains straightforward due to its 66W TDP, often using a single fan heatsink in reference designs. This setup maintains temperatures below 70°C under load in well-ventilated cases. For optimal longevity, pair it with a 300-400W PSU. Recommended configurations focus on legacy games at reduced resolutions. The following list highlights suitable titles and settings:

  • Counter-Strike: Source at 1080p, high settings (60+ FPS).
  • League of Legends at 1080p, medium settings (100+ FPS).
  • Portal 2 at 720p, high settings (50+ FPS).
  • Dirt 3 at 720p, medium settings (40+ FPS).
  • BioShock Infinite at 720p, low settings (30+ FPS).
  • Minecraft at 1080p, high settings (60+ FPS).
