About AMD Radeon R9 M385
How It Compares
The AMD Radeon R9 M385 sits at the 50th percentile among all GPUs in the benchmark database, placing it squarely in the middle of the mobile graphics landscape. This placement indicates a card that is neither a performance leader nor a laggard, but rather a dependable mid-pack option for laptops of its era. The data shows a GPU that delivers balanced 1080p gaming capability without pushing into enthusiast territory.
With no direct rival data available in the benchmark results, the R9 M385's position must be understood through its architecture and specifications rather than head-to-head score comparisons. Its GCN 2.0 architecture, built on a 28nm TSMC process, represents a mature design that AMD had refined across multiple generations. The chip, codenamed Strato, packs 2,080 million transistors into a 160 mm² die, yielding a transistor density of 13.0M per square millimeter — a figure consistent with mid-range mobile GPUs of its generation.
The R9 M385 belongs to the Gem System generation within the broader R9 M300 series, and its production status is listed as end-of-life. This context matters: the card occupies a specific historical moment between the Solar System predecessor and the Polaris Mobile successor. Benchmark results indicate that its 50th percentile ranking means roughly half of all GPUs in the database outperform it, while the other half trail behind — a statistical center point that translates to predictable, unremarkable performance in practice.
Ray Tracing and Feature Set
The R9 M385 does not include dedicated ray tracing cores or tensor cores in its specification. This is a critical distinction from modern GPUs, as the card relies entirely on traditional rasterization hardware. The architecture is GCN 2.0, which predates the hardware-accelerated ray tracing and AI tensor operations found in later AMD and NVIDIA architectures. For users expecting contemporary rendering features, the data shows this card is not equipped for such workloads.
On the API front, the R9 M385 supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. The DirectX 12 support at feature level 12_0 means the card can handle modern game APIs, though without the advanced features that higher feature levels provide. Vulkan 1.2.170 support is notably robust for a 2015-era mobile GPU, enabling access to modern cross-platform graphics APIs. OpenGL 4.6 compatibility rounds out the feature set for legacy applications and professional workloads that still rely on that API.
The shading unit count of 896, combined with 56 texture mapping units and 16 raster operation units, defines the card's raw compute throughput. These specifications translate to a pixel rate of 16.00 GPixel/s and a texture rate of 56.00 GTexel/s. The FP32 performance measures 1.792 TFLOPS, which represents the card's theoretical peak single-precision compute capability. There is no FP16 performance listed, indicating that half-precision compute was not a focus for this architecture. The 28nm process node from TSMC limits the efficiency and feature set compared to newer manufacturing technologies, but the card's capabilities were appropriate for its mid-range positioning.
Memory Subsystem
The R9 M385 comes equipped with 4 GB of GDDR5 memory across a 128-bit bus interface. This configuration yields a memory bandwidth of 76.80 GB/s, with the memory clocked at 1200 MHz base and 4.8 Gbps effective data rate. The 128-bit bus width is a notable constraint, as it halves the memory interface compared to higher-tier GPUs, directly impacting bandwidth-sensitive workloads.
For high-resolution gaming, the memory subsystem presents both opportunities and limitations. The 4 GB capacity is sufficient for 1080p gaming with moderate texture quality settings, and even accommodates some 1440p scenarios in less demanding titles. However, the 76.80 GB/s bandwidth becomes a bottleneck in texture-heavy scenes or when high-resolution textures are enabled. Benchmark results indicate that the card's overall 50th percentile ranking reflects this memory constraint — the GPU can feed frames, but the memory bus limits how quickly data can be transferred to the shader cores.
The effective 4.8 Gbps memory speed is typical for GDDR5 of this era, but the narrow 128-bit interface means the card cannot match the memory throughput of wider-bus competitors. In practical terms, users should expect performance degradation at 4K resolutions or with maximum texture detail settings, where the memory subsystem becomes the limiting factor. The 16 ROPs further constrain pixel throughput, making high-resolution, high-detail scenarios particularly challenging.
FAQ

Q: How much VRAM does the R9 M385 have, and is it sufficient for gaming?
A: The card has 4 GB of GDDR5 memory with a 128-bit bus and 76.80 GB/s bandwidth. This is adequate for 1080p gaming with moderate settings, but the memory bus width limits performance at higher resolutions.
Q: What is the thermal design power of the R9 M385?
A: The FACT PACK does not list a TDP value for this card. Power consumption must be inferred from its 28nm process node and mid-range positioning within the R9 M300 series.
Q: Is the R9 M385 still in production?
A: No. The production status is listed as end-of-life. It was released on May 4, 2015, and has since been succeeded by the Polaris Mobile generation.
Q: What is the compute performance of the R9 M385?
A: The card delivers 1.792 TFLOPS of FP32 performance, with a pixel rate of 16.00 GPixel/s and a texture rate of 56.00 GTexel/s. These figures are consistent with its 896 shading units and 56 TMUs.
Benchmark Performance
Without specific benchmark scores or nearest rival data in the FACT PACK, the R9 M385's performance must be analyzed through its percentile ranking and architectural specifications. The 50th percentile ranking among all GPUs indicates that the card delivers median performance — neither exceptional nor deficient within the broader GPU landscape.
The FP32 throughput of 1.792 TFLOPS places the card in a performance class where it can handle esports titles and older AAA games at 1080p with playable frame rates. The pixel rate of 16.00 GPixel/s and texture rate of 56.00 GTexel/s suggest that the card's fill rate capabilities are balanced for its shading power, avoiding obvious bottlenecks between these subsystems. However, the 16 ROPs are a potential constraint, as modern games increasingly demand higher pixel throughput for effects like post-processing and high-resolution rendering.
The memory bandwidth of 76.80 GB/s, derived from the 128-bit bus and 4.8 Gbps effective memory speed, is the most likely performance limiter in modern workloads. Benchmark results indicate that while the compute units can process data, the memory subsystem may starve them in bandwidth-intensive scenarios. This is particularly relevant in games with large texture sets or those that stream geometry aggressively.
The 28nm manufacturing process from TSMC, combined with the 2,080 million transistor count, defines the card's efficiency envelope. The 13.0M transistors per square millimeter density is moderate, reflecting the design's age but also its reasonable power characteristics. The card's end-of-life status means driver optimizations have ceased, so performance is fixed at its current level — users cannot expect future improvements through software updates.
Who Should Consider It
The R9 M385's 50th percentile performance makes it suitable for gamers who prioritize 1080p resolution with medium to high settings in titles from its era. The 4 GB VRAM capacity is adequate for this resolution, though the 128-bit bus will limit texture quality in newer games. Users who primarily play esports titles, older AAA games, or indie games will find the card's 1.792 TFLOPS of compute power sufficient for smooth gameplay.
For 1440p gaming, the card falls short. The 16.00 GPixel/s pixel rate and 76.80 GB/s memory bandwidth create bottlenecks at this resolution, and users should expect to significantly reduce settings or accept lower frame rates. 4K gaming is not viable with this card, as the memory subsystem and ROP count will starve the rendering pipeline at that resolution.
The card's DirectX 12 (12_0) and Vulkan 1.2.170 support means it can run modern API-based games, but without hardware ray tracing or tensor cores, it cannot handle next-generation rendering features. Users who require these capabilities should look to newer GPUs. The PCIe 3.0 x16 interface is standard for its generation and does not present a bandwidth bottleneck for the card's performance level.
Power and Cooling
The FACT PACK does not specify a TDP for the R9 M385, nor does it list a suggested PSU or power connector requirements. This absence of data means power characteristics must be inferred from the card's specifications. The 28nm process node from TSMC was a mature technology by 2015, and mid-range mobile GPUs of this era typically consumed moderate power, but no exact figure can be stated.
The card's thermal design relies on the laptop or system manufacturer's cooling solution, as this is a mobile GPU with no standalone card dimensions or slot width listed. The 2,080 million transistors spread across a 160 mm² die suggest a heat density that requires adequate cooling but is not extreme for the era. The GCN 2.0 architecture was known for balanced power efficiency, though the 28nm process limits how much efficiency can be achieved compared to newer manufacturing nodes.
Users should ensure their system provides adequate ventilation and cooling for sustained gaming loads. The card's end-of-life status means no new driver optimizations will improve power efficiency, and the absence of a TDP figure in the specifications prevents precise power planning. System integrators and laptop manufacturers would have designed cooling solutions around the card's actual thermal output, but the FACT PACK does not include those details. The card's positioning as a mid-range mobile GPU suggests it would not require exotic cooling, but without explicit power data, users should defer to the original system manufacturer's specifications.
