AMD Radeon HD 6850M

The AMD Radeon HD 6850M is a mobile graphics processor built on the TeraScale 2 architecture, fabricated by TSMC on a 40 nm process node. It integrates 1,040 million transistors on a 166 mm² die, resulting in a transistor density of 6.3M per mm². This end-of-life part, released in January 2011, targets the mainstream laptop segment and carries a 50th percentile ranking among all GPUs in the database, indicating it sits squarely in the middle of the performance distribution.

Benchmark Performance

The HD 6850M’s benchmark data shows no recorded average score, and the nearestRivals array is empty, meaning direct percentage comparisons against specific competitors are not available from the fact pack. However, the 50th percentile ranking provides a meaningful anchor: half of all GPUs in the database score higher, and half score lower. This places the chip in the middle tier of mobile graphics solutions from its era, neither a high-end part nor an entry-level offering.

The raw compute specifications support this positioning. The GPU delivers 1,080.0 GFLOPS of single-precision floating-point performance, driven by 800 shading units operating at the memory clock’s effective rate. Texture fill rate stands at 27.00 GTexel/s, while pixel throughput reaches 10.80 GPixel/s. These figures indicate a balanced design that can handle contemporary titles at moderate settings, though the lack of direct rival scores prevents quantifying how much faster or slower it is than specific alternatives. The 50th percentile suggests it outperforms a significant portion of the GPU landscape, but the absence of benchmark entries means the analysis must rely on architectural and bandwidth characteristics rather than synthetic test results.

Memory Subsystem

The HD 6850M pairs its compute cores with a 1024 MB GDDR3 frame buffer accessed via a 128-bit memory bus. Memory runs at 800 MHz, translating to 1600 Mbps effective data rate, which yields a peak bandwidth of 25.60 GB/s. This configuration is modest by modern standards but was typical for mobile GPUs at the time of release.

For high-resolution workloads, the 128-bit bus and 25.60 GB/s bandwidth create a clear bottleneck. At 1080p or higher, demanding textures and post-processing effects require frequent frame buffer reads and writes, and the relatively narrow bus will struggle to keep up with the shading units’ compute throughput. The 1 GB capacity is adequate for 720p and most 1080p titles of the 2011 era, but it may force texture quality reductions in games with large asset loads. GDDR3, rather than the faster GDDR5 found in some contemporaries, further limits burst transfers. The data indicates that the memory subsystem is designed for balanced 720p gaming or light 1080p use, not for pushing maximum detail at high resolutions. Users targeting 1440p or beyond would find the 25.60 GB/s bandwidth and 1 GB capacity severely restrictive, leading to stutter and texture pop-in.

Who Should Consider It

Given its 50th percentile standing and memory characteristics, the HD 6850M suits users who play older or less demanding titles at 720p with medium settings. At this resolution, the 1,080.0 GFLOPS compute throughput and 27.00 GTexel/s texture rate can maintain playable frame rates in titles from the late 2000s and early 2010s, provided the game does not rely heavily on memory bandwidth. Esports titles from that era, such as lighter competitive shooters, would run comfortably.

For 1080p gaming, the GPU becomes situational. The 25.60 GB/s bandwidth will limit performance in games with large, high-resolution textures or heavy anti-aliasing. Users willing to lower graphical presets to low or medium and disable demanding effects like shadows and ambient occlusion can still achieve acceptable frame rates in many titles. However, the 1 GB VRAM may cause issues in games that exceed that capacity, resulting in texture loading delays or reduced draw distances.

The HD 6850M is not suitable for high-refresh-rate gaming or modern AAA releases that require more than 1 GB VRAM and significantly higher bandwidth. The 50th percentile ranking confirms it is a mid-pack part, best paired with modest expectations. It also appeals to retro-gaming enthusiasts building a portable system for older titles, where its 40 nm process and 50 W TDP keep thermals manageable. Users who prioritize maximum settings or future-proofing should look elsewhere, as the data shows no headroom for demanding workloads.

How It Compares

The fact pack lists no nearest rivals for the HD 6850M, making direct comparisons impossible. The nearestRivals array is empty, and no alternative GPU names, scores, or deltaPct values are provided. Consequently, the analysis cannot state that it is a certain percentage faster or slower than any specific product.

What the data does reveal is its relative standing through the percentile system. A 50th percentile rank means it outperforms exactly half of all GPUs in the database. This is a broader comparison than a head-to-head, but it lacks the specificity of rival deltas. The chip’s predecessor, Manhattan, and successor, London, are named but no performance figures accompany them, so no generational comparison can be quantified. The architecture, TeraScale 2, is shared with other AMD parts of its generation, but without benchmark scores, the HD 6850M’s position among them remains undefined. In the absence of rival data, the only concrete comparison is the percentile, which frames it as a median performer—useful for general positioning but not for precise competitive analysis.

Power and Cooling

The HD 6850M carries a thermal design power (TDP) of 50 W, a modest figure that reflects its 40 nm manufacturing process and mid-range positioning. This TDP is low enough for integration into thin-and-light laptops without elaborate cooling solutions, though the fact pack does not specify slot width, power connectors, or a suggested PSU. Since this is a mobile GPU, power delivery is handled by the laptop’s internal design rather than a desktop power supply.

The 50 W TDP implies that a capable cooling solution—such as a dual-heatpipe assembly or a small blower fan—would suffice to maintain stable clocks under load. The data does not provide boost or base clock rates, so sustained performance characteristics are unknown, but the power envelope suggests the GPU can operate without excessive thermal throttling in a well-designed chassis. The PCIe 2.0 x16 bus interface draws additional power from the motherboard slot, though the exact contribution is not quantified. For portable devices, the 50 W figure means battery life impact is moderate; gaming sessions will drain the battery faster than light tasks, but the power draw is not extreme enough to require a high-capacity adapter beyond what typical laptops include.

The absence of a suggested PSU rating reflects the mobile nature of this part—desktop power supply recommendations do not apply. The display outputs are listed as "Portable Device Dependent," confirming that connectivity varies by laptop model. The 40 nm process helps keep heat density lower than older nodes, but the 1,040 million transistors on a 166 mm² die still generate measurable heat under sustained load. Overall, the power and cooling data indicate a component that is manageable for original equipment manufacturers, but the end-of-life status means modern laptops will not feature it, and users seeking replacements must rely on legacy systems.
