AMD Radeon HD 6850 1440SP Edition

Power and Cooling — TDP, PSU recommendation, connector requirements

The AMD Radeon HD 6850 1440SP Edition carries a 151 W TDP, placing it in a category that demands careful attention to system power delivery rather than exotic cooling solutions. The data specifies a suggested PSU rating of 450 W, which is a modest requirement for a card of this era, indicating that most mid-range desktop power supplies from its generation could handle it without issue. The power delivery system relies on two 6-pin PCIe power connectors, a standard configuration that was common for performance-oriented graphics cards at the time of its release. This dual-connector setup ensures that the card draws power from the PSU in a balanced manner, reducing strain on any single rail.

The physical design is a dual-slot solution, meaning it occupies two expansion brackets in a chassis. This is typical for cards with a 151 W TDP, as the additional slot width accommodates a larger heatsink and fan assembly necessary for adequate thermal dissipation. The card's length measures 241 mm (9.5 inches), which is a relatively compact footprint for a dual-slot cooler, making it compatible with a wide range of mid-tower and full-tower cases from its era. The 40 nm process node from TSMC, with 2,154 million transistors packed into a 334 mm² die, contributes to a transistor density of 6.4M per mm², which is a key factor in the thermal characteristics of the chip. The Cypress chip, built on the TeraScale 2 architecture, generates heat that the dual-slot cooler must manage, and the 151 W TDP figure suggests that a capable air cooler with heat pipes or a dense fin array would be sufficient, though the data does not specify the exact cooler design.

It is worth noting that the suggested PSU of 450 W is a system-level recommendation, not just a card-level one. This implies that the card's power draw, combined with a typical CPU and other components, stays within the 450 W envelope. The two 6-pin connectors are a hard requirement — no adapter is mentioned in the facts, so the PSU must have native support for these connectors. For users with older power supplies lacking these connectors, an adapter would be needed, but the data does not confirm any such accessory. The end-of-life production status suggests that this card is now a legacy product, and its power requirements remain relevant only for those maintaining or retrofitting older systems. The absence of a base or boost clock in the data means that power scaling behavior under load cannot be quantified, but the TDP figure serves as the primary thermal design constraint.

Ray Tracing and Feature Set — RT/tensor cores, API support from facts

The AMD Radeon HD 6850 1440SP Edition predates the era of dedicated ray tracing hardware. The FACT PACK lists no RT cores and no tensor cores, indicating that this card has no hardware acceleration for real-time ray tracing or AI-based upscaling techniques such as DLSS. This is a fundamental architectural limitation: the TeraScale 2 design focuses purely on traditional rasterization and compute workloads. The card's shading units number 1,440, with 72 texture mapping units and 32 ROPs, which are the building blocks for conventional 3D rendering but offer no specialized pathways for ray traversal or denoising operations.

API support in the data is limited to DirectX 11.2 (11_0) and OpenGL 4.4. Notably, there is no Vulkan support listed, which means modern titles relying on Vulkan's lower-level access and multi-threading benefits will not run on this hardware. The DirectX 11.2 (11_0) designation indicates feature level 11_0, which is the baseline for DirectX 11, so the card supports tessellation, compute shaders, and other DX11-era features, but not the enhanced features of DirectX 11.2 such as conservative rasterization or tiled resources. OpenGL 4.4 provides a reasonably modern OpenGL feature set for its time, covering a wide range of older and mid-era games. The absence of Vulkan is a significant gap, as many recent titles have dropped or deprecated OpenGL in favor of Vulkan. For ray tracing specifically, the card is entirely reliant on software implementations, which are typically too slow for real-time use, and the data shows no evidence of any hybrid or software-based RT acceleration.

The display outputs include 2x DVI, 1x HDMI 1.3a, and 1x DisplayPort 1.1. HDMI 1.3a supports 1080p at high refresh rates but lacks the bandwidth for 4K at 60 Hz with deep color. DisplayPort 1.1 is similarly limited to lower resolutions and refresh rates compared to modern DisplayPort versions. These outputs are adequate for multi-monitor setups at 1080p or 1440p, but they will not drive cutting-edge displays at their full capabilities. The pixel rate of 23.20 GPixel/s and texture rate of 52.20 GTexel/s give a sense of the card's fill-rate capabilities, which are relevant for traditional rendering but irrelevant to ray tracing. In summary, the feature set is firmly rooted in the pre-RT era, and any expectation of hardware-accelerated ray tracing or tensor-based features is unsupported by the data.

Benchmark Performance — analyze scores vs rivals with exact % deltas

The FACT PACK provides a percentile rank of 50 among all GPUs, which places this card at the exact median of the benchmark database. This is a critical anchor point: the card is neither a low-end performer nor a high-end one; it sits squarely in the middle of the distribution. However, the avgBenchmarkScore is listed as 0, and the benchmarks array is empty, meaning there are no raw score values to directly quantify its performance. The nearestRivals array is also empty, which eliminates the possibility of direct percentage comparisons to specific competing cards. This is an unusual situation where the percentile rank is the only quantitative performance indicator available.

The 50th percentile implies that in a hypothetical head-to-head against all other GPUs in the database, this card would outperform roughly half and underperform the other half. For a card released in August 2012, this median positioning suggests it was a competent mid-range performer at launch, but the data does not reveal how it stacks against specific contemporaries. The FP32 compute throughput of 2.088 TFLOPS, combined with a texture rate of 52.20 GTexel/s and pixel rate of 23.20 GPixel/s, provides theoretical peak figures that are useful for understanding its compute ceiling. The 1,440 shading units are a notable increase over the standard HD 6850, which traditionally had 960 shaders, but the FACT PACK does not provide a direct comparison to the standard version.

Without rival data, the benchmark analysis must rely on the percentile rank as the sole comparative metric. The 50th percentile is a neutral position — it indicates that the card is not a standout performer nor a laggard. For gaming at 1080p, which was the dominant resolution in 2012, this median position would suggest playable frame rates in most titles at medium to high settings, but the data does not provide specific frame rates. The lack of nearestRivals means that any claim of being "30% faster than X" is impossible to substantiate from the FACT PACK. The analysis must therefore focus on what the percentile implies: a balanced, middle-of-the-road performer that does not excel in any particular benchmark category but is broadly capable. The empty benchmarks array is a data gap, not a performance statement, and it limits the depth of quantitative analysis that can be presented.

How It Compares

The nearestRivals array in the FACT PACK is empty, which means there are no direct competitor names, scores, or deltaPct values to reference. This is a notable absence, as it prevents any specific head-to-head percentage comparisons. The only comparative datum available is the 50th percentile rank, which positions the card at the median of all GPUs. In the absence of named rivals, the comparison must be framed in terms of this percentile. A 50th percentile rank means that in a sorted list of all GPUs by benchmark score, this card would sit exactly in the middle. This implies that it is faster than half of all GPUs in the database and slower than the other half. It does not tell us which specific cards are above or below it, but it does give a sense of overall standing. The card's 2.088 TFLOPS FP32 throughput and 128.0 GB/s memory bandwidth are the underlying compute resources that likely contribute to this median position, but without rival data, these figures cannot be contextualized against specific products. The empty nearestRivals field is a limitation of the data, not a reflection of the card's performance. If rival data were available, the analysis would show exact percentage deltas, but as it stands, the percentile is the only comparative metric.

Who Should Consider It

Given the 50th percentile rank, this card is suited for users targeting 1080p resolution with moderate graphical demands. The 1,024 MB VRAM and 128.0 GB/s bandwidth suggest that 1080p is the sweet spot; higher resolutions like 1440p or 4K would likely exceed the memory capacity and bandwidth, leading to texture thrashing and reduced performance. The 2.088 TFLOPS FP32 compute is adequate for DirectX 11-era games at medium settings, but the card is not designed for high-refresh-rate esports titles at competitive settings, nor for demanding AAA games at maximum details. The 50th percentile rank indicates a balanced performer: it will handle older or less demanding titles smoothly at high settings, while newer games from its era will require dialing back to medium or low presets. For users with a 450 W PSU and a system that already has two 6-pin connectors, this card is a drop-in upgrade for legacy systems. However, the lack of Vulkan support and the absence of RT cores make it unsuitable for modern titles that rely on these features. The 2x DVI, 1x HDMI 1.3a, and 1x DisplayPort 1.1 outputs are sufficient for a 1080p multi-monitor setup, but they cannot drive 4K displays at 60 Hz. In summary, the card is best for retro gaming at 1080p, or as a budget placeholder for a system that does not require modern API features.

Memory Subsystem

The memory subsystem is built around 1,024 MB of GDDR5 memory, which is a modest capacity by modern standards but was typical for a mid-range card in 2012. The 256-bit bus width is a key strength, as it allows for a memory bandwidth of 128.0 GB/s. This bandwidth figure is critical for high-resolution gaming, because it determines how quickly textures and geometry data can be fed to the GPU's shading units. At 1080p, 128.0 GB/s is sufficient for most games of the era, but at 1440p or higher, the bandwidth becomes a bottleneck. The memory clock is 1000 MHz, with an effective data rate of 4 Gbps, which is the GDDR5 standard for that generation.

The 1,024 MB capacity is the more limiting factor at high resolutions. Modern games with high-resolution texture packs can easily exceed 2 GB of VRAM usage, and even games from 2012 could approach 1 GB at maximum settings with anti-aliasing enabled. Once the VRAM is full, the card must spill over to system memory via the PCIe 2.0 x16 interface, which has significantly lower bandwidth than the dedicated 128.0 GB/s. This results in stuttering and frame drops. The 256-bit bus width partially compensates for the modest capacity by providing efficient data movement, but it cannot overcome the hard limit of 1 GB. The pixel rate of 23.20 GPixel/s and texture rate of 52.20 GTexel/s are directly tied to the memory subsystem's ability to supply data to the ROPs and TMUs. At 128.0 GB/s, the card can sustain these fill rates without starving the pipeline, but any increase in resolution or texture complexity will strain the bandwidth. For users considering this card for 4K gaming, the memory subsystem is a clear disqualifier — the 1 GB capacity and 128.0 GB/s bandwidth are simply insufficient for the data demands of 4K textures. The 2x DVI and DisplayPort 1.1 outputs also lack the bandwidth for 4K at 60 Hz, further reinforcing that the card is not designed for ultra-high resolutions.
