About AMD Radeon R6 M340DX
# AMD Radeon R6 M340DX
The AMD Radeon R6 M340DX is an integrated graphics processor (IGP) built on the 28 nm process at TSMC, utilizing the GCN 1.0 architecture with the Jet chip. It is classified as end-of-life and scored at the 50th percentile among all GPUs in the database, placing it squarely in the mid-range of the performance distribution. With a 955 MHz base clock and 1030 MHz boost clock, this IGP delivers 791.0 GFLOPS of FP32 compute, a pixel rate of 8.240 GPixel/s, and a texture rate of 24.72 GTexel/s, making it a modest performer suited for casual use rather than demanding workloads.
How It Compares
The R6 M340DX has no nearest rivals listed in the database, meaning there are no direct comparison points from benchmark data to anchor its relative standing. This absence of rival scores suggests the GPU occupies a niche position where few products share its exact configuration—integrated graphics with 384 shading units, 24 TMUs, and 8 ROPs. Without rival deltas, the percentile ranking of 50 becomes the primary reference: it sits exactly at the median of all GPUs tracked, indicating it outperforms half of the field while trailing the other half. In practical terms, this places it above the weakest integrated solutions but well below any discrete graphics card, even entry-level ones.
The lack of nearestRivals data also means that the M340DX's performance profile is defined entirely by its own specifications rather than competitive benchmarks. Its 384 shading units and 1030 MHz boost clock yield a texture rate of 24.72 GTexel/s, which would position it firmly in the lower tier of graphics processors. Users coming from older integrated graphics may notice a step up, but anyone with experience using a dedicated GPU from the same era would find the M340DX underwhelming. The 50th percentile ranking is a statistical midpoint, not a recommendation—it indicates a balanced position in a crowded field where most GPUs cluster around similar modest performance levels.
Memory Subsystem
The R6 M340DX uses a system-shared memory configuration, with no dedicated VRAM of its own. Memory size, type, and bus width are all listed as "System Shared," meaning the GPU borrows from the host system's main memory rather than having its own pool. The bandwidth is described as "System Dependent," which is a crucial caveat: performance will vary significantly based on the system's RAM speed, channel configuration, and capacity. In a dual-channel setup with fast DDR3 or DDR4 memory, the effective bandwidth could be respectable, but in a single-channel or low-speed configuration, the GPU will be severely bandwidth-starved.
For high resolutions, this shared memory architecture is a fundamental limitation. The 8 ROPs, combined with a pixel rate of 8.240 GPixel/s, limit fill-rate performance, while the system-dependent bandwidth means that texture-heavy scenes at 1440p or 4K will likely stutter or drop frames. At 1080p, the M340DX can handle older or less demanding titles at low to medium settings, but the lack of dedicated VRAM means textures must reside in system memory, increasing latency and reducing effective throughput. The 28 nm process and 690 million transistors on a 56 mm² die also indicate a design optimized for power efficiency rather than memory bandwidth, reinforcing that this is not a high-resolution gaming solution. For 720p or 1080p with modest settings, the shared memory approach is workable, but it will not scale to higher resolutions without significant performance degradation.
Ray Tracing and Feature Set
The R6 M340DX has no dedicated ray tracing cores or tensor cores, which is expected for a GPU from the GCN 1.0 architecture era. Ray tracing acceleration is entirely absent from this design, so any ray-traced effects would need to be computed on the general-purpose shading units, resulting in extremely poor performance. The API support includes DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170, which covers modern graphics APIs but with the DX12 feature level limited to 11_1, meaning some newer DX12 features may not be available. The Vulkan support at version 1.2.170 is reasonably current and could allow for efficient draws in Vulkan-based games, though the underlying hardware will still bottleneck.
Without tensor cores, any AI-assisted features like DLSS or similar upscaling techniques are unavailable. The GPU relies purely on traditional rasterization, and its GCN 1.0 architecture lacks the specialized hardware found in later generations. The 384 shading units can handle compute workloads, but they are not optimized for the parallel matrix operations that acceleration cores provide. For users interested in ray tracing, this GPU is a non-starter—there is no hardware support, and software-based ray tracing would render at unplayable frame rates. The feature set is best described as functional for basic 3D graphics and video playback, but it offers no modern bells and whistles.
Who Should Consider It
Given the 50th percentile ranking and the absence of rival comparisons, the R6 M340DX is best suited for users who need basic graphics output without any gaming aspirations. At 720p resolution, the GPU can handle light titles, older games, or indie releases at low settings, but even those may struggle if the system memory is slow or shared with other applications. For 1080p, the data suggests it will manage desktop productivity, video streaming, and casual web browsing without issue, but gaming at that resolution will require reduced settings and older titles. The 791.0 GFLOPS of FP32 compute is roughly comparable to entry-level discrete GPUs from the same era, but the system-shared memory and IGP form factor limit its effectiveness.
Users with modern AAA games, high-refresh-rate displays, or creative workloads like video editing or 3D rendering should avoid this GPU entirely. Its 8 ROPs and 24 TMUs are insufficient for those tasks, and the lack of dedicated VRAM compounds the problem. The M340DX is a product of its time—2015's mobile and compact desktop systems—and it is now end-of-life. Anyone still using it should consider it a legacy component, not a future-proof solution. For office work, media consumption, and light 2D applications, it suffices; for anything more, it will disappoint.
Benchmark Performance
With no benchmarks listed and a benchmark score of 0, the R6 M340DX's quantitative performance is not directly measured in the database. The percentile ranking of 50, however, provides a statistical anchor: it sits exactly at the median of all GPUs, meaning half of the GPUs tracked perform better and half perform worse. Without nearestRivals or deltaPct values, there are no exact percentage deltas to cite, but the 50th percentile implies a balanced position where the GPU is neither a standout nor a laggard. The FP32 compute of 791.0 GFLOPS and texture rate of 24.72 GTexel/s are the only hard performance numbers available, and they indicate a capability level roughly aligned with the median ranking.
The pixel rate of 8.240 GPixel/s, combined with the system-dependent memory bandwidth, suggests that fill-rate-bound scenes will be the primary bottleneck. In contrast, the texture rate is relatively higher, indicating the GPU can handle texture-heavy workloads better than pure pixel pushing. This is typical of integrated graphics with limited ROPs. The 1030 MHz boost clock is modest, and the 28 nm process node limits thermal and power efficiency compared to newer nodes. In practice, the M340DX will likely deliver playable frame rates at 720p for esports titles like League of Legends or Counter-Strike: Global Offensive, but it will struggle with anything more demanding. The absence of benchmark data means these conclusions are inferred from specifications rather than direct measurements, but the architecture and clock speeds support this assessment.
Power and Cooling
The R6 M340DX has no TDP listed in the database, and it is classified with a slot width of "IGP," meaning it is integrated into the motherboard or processor package. As an integrated GPU, it draws power from the host system's power delivery, sharing the thermal envelope with the CPU. The 28 nm process node, with 690 million transistors on a 56 mm² die, suggests a relatively low power draw, but without a TDP figure, no exact wattage can be stated. There is also no suggested PSU recommendation or power connector requirement, which is consistent with an IGP that does not require external power. The system's overall PSU must supply enough wattage for the CPU and other components, but the GPU itself adds negligible load.
Cooling is likewise handled by the system's existing thermal solution, typically a heatsink or fan designed for the CPU/APU package. The lack of a discrete cooler or power connector means the M340DX is a low-maintenance component that does not affect system cooling requirements beyond the integrated design. Users should ensure their system has adequate airflow, but the GPU itself will not generate excessive heat. The end-of-life status indicates that AMD no longer produces this GPU, but for systems that still use it, the power and cooling demands are minimal and well within the capabilities of standard desktop or laptop designs.
