• Transistor Count: ~1.7 billion

• Stream Processors: 960

• Texture Units: 48

• ROP Units: 32

• Core Clock: 775 MHz (reference); some factory-overclocked versions may reach up to 900 MHz

• Architecture: VLIW5, part of AMD’s Radeon HD 6000 series

🧠 Memory

• Memory Size: 1 GB

• Memory Type: GDDR5

• Memory Interface: 256-bit

• Memory Clock Speed: 1000 MHz (4000 MHz effective)

• Memory Bandwidth: Approximately 128 GB/s

🔌 Power & Cooling

• Typical Board Power (TDP): ~127W

• Power Connectors Required: One 6-pin PCIe power connector (some variants may use two)

• Recommended PSU: 500W or higher

• Cooling System:

  • Dual-slot cooler with a single axial fan (reference design)

  • Many aftermarket versions (like those from Sapphire, HIS, Gigabyte, XFX) feature custom dual-fan or heatpipe designs for better cooling and quieter performance

📺 Display Outputs

• Standard Ports:

  • 2× DVI (DVI-I and DVI-D)

  • 1× HDMI 1.4a (supports 3D Blu-ray, 7.1 surround audio)

  • 1× DisplayPort 1.2 (supports daisy chaining)

• Maximum Digital Resolution: 2560×1600

• Multi-Monitor Support: Up to 3 displays natively using AMD Eyefinity (up to 6 with DisplayPort hub)

🎮 Performance

• 1080p Gaming:

  • Crysis (Very High, 4xAA): ~33 fps

  • DiRT 2 (Ultra): ~53 fps

  • Battlefield: Bad Company 2 (High): ~58 fps

  • Performs slightly better than Nvidia’s GTX 460 1GB in most games

• Target Audience: Mid-range gamers playing titles from the 2010–2015 era on medium to high settings

🧩 Features

• DirectX Support: DirectX 11

• OpenGL Support: OpenGL 4.1

• Shader Model: 5.0

• OpenCL Support: OpenCL 1.1

• Other Technologies:

  • AMD Eyefinity (multi-monitor support)

  • AMD CrossFireX (multi-GPU support)

  • Unified Video Decoder 3 (UVD3) for smooth HD/3D video playback

  • HDMI audio passthrough (supports Dolby TrueHD and DTS-HD Master Audio)

🌡 Thermal and Efficiency

• Idle Power Consumption: Very low due to aggressive power gating

• Load Power Consumption: ~127W typical

• Thermal Output: Stock cards may reach ~80–83°C under full load; custom coolers often reduce this by 10–15°C

• Noise Levels: Moderate under load with reference cooler; quieter with third-party designs

🛠 Reliability & Longevity

• Driver Support: Last supported by AMD’s legacy drivers; no longer receives modern updates

• Build Quality: Solid PCB and components; aging cards may benefit from fresh thermal paste and fan inspection

• Aftermarket Variants: Widely available from brands like Sapphire, HIS, XFX, Gigabyte, ASUS

✅ Ideal For

• Budget gaming builds or legacy PCs

• 1080p gaming with older or esports titles (CS:GO, League of Legends, Dota 2)

• Media center PCs (thanks to UVD3 and HDMI 7.1 audio)

• Multi-monitor productivity setups using Eyefinity
