About AMD Radeon HD 6850

The AMD Radeon HD 6850 launched on October 21, 2010, positioning itself as a budget-friendly entry into the mid‑range market. Built on the 40 nm TeraScale 2 architecture, it utilizes a PCIe 2.0 x16 interface to communicate with the host system. With a 1024 MB GDDR5 memory pool, the card offers a respectable 5 Gb/s memory bandwidth for its class. Its 127 W TDP keeps power draw modest, allowing integration into compact builds without demanding exotic power supplies. The GPU’s core features a 40‑stage pipeline and 800 Mhz shader clock, which were competitive at the time of release. Priced at $179 USD, the Radeon HD 6850 aimed to deliver solid gaming performance without breaking the bank.

In synthetic testing, the card scores 1,945 points in PassMark’s 3D Graphics benchmark, placing it firmly in the low‑mid tier of its era. Compute workloads register 750 points, while the G2D score of 436 points reflects its modest rasterisation capabilities. DirectX 9 and DirectX 10 scores are 50 and 15 points respectively, indicating that the 6850 struggles with newer APIs but still holds up in older titles. Gaming performance is best observed at 1080p with medium settings, where titles like World of Warcraft and Diablo III run smoothly. The card’s GDDR5 memory delivers faster data transfers than its DDR3‑based rivals, which translates into a noticeable edge in texture‑heavy scenes. Power consumption remains under 130 W under load, meaning a single‑rail 500 W PSU can comfortably support a system built around this GPU. For enthusiasts who enjoy tweaking, the 6850 offers a decent overclock headroom of around 10 % on both core and memory clocks.

  1. Gaming performance: Handles older DirectX 9/10 titles at 1080p with medium settings.
  2. Advanced graphics: TeraScale 2 pipeline with GDDR5 memory for smoother texture handling.
  3. Video memory: 1 GB of fast GDDR5 provides sufficient bandwidth for mid‑range workloads.

When pairing the Radeon HD 6850 with a modest CPU, the bottleneck often shifts to the processor, making it a good match for quad‑core CPUs from the same generation. Its low TDP also makes it suitable for HTPC builds where noise and heat are critical concerns. The card shines in scenarios where power efficiency outweighs raw horsepower, such as casual e‑sports titles and older DirectX 9 games. However, modern AAA releases will demand significant compromises in resolution or visual fidelity. The 6850 remains an attractive option for retro‑gaming rigs looking to recapture the feel of the early 2010s era. In short, the 6850 delivers a balanced mix of performance, power draw, and price that still appeals to hardware hobbyists who enjoy building on a shoestring budget.
