AMD Radeon R7 M365X

The AMD Radeon R7 M365X is a 28 nm mobile graphics processor built on the GCN 1.0 architecture, using the Litho chip with 950 million transistors on a 77 mm² die. It targets the entry-level segment of the laptop market, with an average benchmark score of 5409 placing it at the 31st percentile of all GPUs. This position indicates a part that delivers basic 3D acceleration and compute capability, but it sits firmly outside the performance tier for demanding gaming or professional workloads.

Benchmark Performance

The R7 M365X’s benchmark results paint a picture of a modest performer. In Geekbench OpenCL, the GPU scores 5941 points, while its Vulkan score is 4876. These scores, when averaged, yield the 5409 figure that defines its standing. The delta between the two tests is notable: the OpenCL score is roughly 22% higher than the Vulkan score, suggesting the architecture’s compute-oriented GCN design is better optimized for general-purpose tasks than for the lower-level graphics API.

Relative to its closest competitors, the R7 M365X is essentially locked in a statistical tie. The AMD Radeon R7 M440 averages 5377 points, which is just 0.6% lower than the M365X’s average. The NVIDIA Quadro P400 sits at 5366 points, a 0.8% deficit. The AMD Radeon R7 M445 trails by 0.9% with a 5361 average. The only rival ahead of it is the AMD Radeon HD 8790M, which posts 5456 points, a marginal 0.9% advantage. These deltas are within the noise of real-world benchmarking, meaning the M365X delivers performance effectively identical to all four of its nearest rivals.

The practical interpretation of these numbers is that the M365X offers no measurable performance edge over its immediate peers. A user moving from an R7 M440 or a Quadro P400 would see no tangible difference in frame rates or compute times. The 0.6% to 0.9% swings are far smaller than the variance typically observed between different driver versions or thermal conditions. The GPU’s 31st percentile ranking confirms this: it outperforms roughly a third of all GPUs in the database, but the vast majority of modern parts, even integrated solutions, will outpace it.

Power and Cooling

The FACT PACK does not list a TDP for the R7 M365X, nor does it specify a suggested power supply or power connector requirements. This absence of data is itself informative for a mobile part. Laptop GPUs are typically constrained by the thermal design of the chassis, and the lack of a published TDP suggests that AMD left power configuration to system integrators. The 28 nm process node, while mature for its era, is not power-efficient by modern standards, so the M365X likely requires a modest cooling solution — a small fan or heatpipe assembly — to maintain stable clocks under load.

Because no wattage figure is provided, any discussion of power draw must remain qualitative. The GPU’s modest transistor count and low shading unit count (384) imply a relatively low power envelope compared to desktop parts of the same generation. The bus interface is PCIe 3.0 x8, which is a half-width link; this reduces the maximum power the slot can deliver compared to a full x16 connection, but mobile GPUs rarely draw significant power from the slot itself. The absence of a suggested PSU rating in the FACT PACK further indicates this is a chip designed for pre-configured laptops rather than DIY desktop builds.

The memory clock is set at 1000 MHz, translating to 4 Gbps effective. This is a standard speed for GDDR5 of that era. Thermal management for such a part would focus on the memory chips and the GPU core, but with only 1024 MB of VRAM, the memory subsystem’s thermal contribution is minimal. System integrators would likely pair this GPU with a basic cooling solution, as the data provides no indication of exotic cooling requirements.

Memory Subsystem

The R7 M365X is equipped with 1024 MB of GDDR5 memory on a 128-bit bus. The memory runs at 1000 MHz, yielding an effective data rate of 4 Gbps. This configuration produces a memory bandwidth of 64.00 GB/s. For a GPU of this class, the bandwidth is a critical bottleneck. The 128-bit bus is narrow by modern standards, and 64 GB/s is sufficient only for light workloads.

At high resolutions, this memory subsystem will struggle. A 1080p frame buffer with modern textures can easily exceed 1 GB of VRAM, and the 1024 MB capacity means the GPU will frequently spill to system memory via the PCIe 3.0 x8 link. That link, with half the lanes of a typical desktop GPU, further compounds the problem by limiting the speed at which data can be swapped. The 64.00 GB/s bandwidth is roughly one-tenth of what a mid-range desktop GPU offers, and it will cap performance in memory-intensive scenes regardless of the core’s compute capability.

The pixel rate of 6.600 GPixel/s and texture rate of 19.80 GTexel/s are consistent with this memory configuration. These figures indicate that the GPU can fill a 1080p frame at modest rates but will choke on 1440p or 4K output, where the fill rate demands exceed the memory subsystem’s throughput. For users targeting high resolutions, the M365X is unsuitable; the data strongly suggests it is a 720p or low-settings 1080p part.

How It Compares

Against the AMD Radeon R7 M440, the M365X holds a 0.6% lead in average score. This is a negligible margin, effectively making the two GPUs interchangeable in real-world use. Both are entry-level parts, and the M365X offers no architectural advantage that would manifest in gaming or application performance.

The NVIDIA Quadro P400 is a workstation-oriented card, yet its average score of 5366 is only 0.8% behind the M365X. This near-parity is remarkable because the Quadro line typically commands a premium for driver certification and stability. The benchmark data shows no such premium in raw compute, meaning a user choosing between them would select based on software ecosystem, not speed.

The AMD Radeon HD 8790M is the only rival that beats the M365X, with a 0.9% higher average score of 5456. This is the previous generation of AMD’s mobile lineup, and its slight edge suggests that the M365X is not a meaningful generational improvement. The delta is so small that it could be attributed to driver maturity or thermal differences in the test laptops.

The AMD Radeon R7 M445 trails by 0.9%, scoring 5361. This is the closest match among the rivals, with a performance gap that is entirely imperceptible. The M445 and M365X are likely the same silicon with different clocks or firmware, as their benchmark scores fall within a 0.9% band. For any practical purpose, these two GPUs are identical.

Ray Tracing and Feature Set

The R7 M365X does not include dedicated ray tracing cores or tensor cores, as those fields are null in the FACT PACK. This places it firmly in the pre-ray-tracing era of GPU design. The architecture is GCN 1.0, which predates hardware-accelerated ray tracing by several generations. Any ray tracing workload would have to run on the 384 shading units, which deliver 633.6 GFLOPS of FP32 compute. That is a minuscule amount of compute for ray tracing, which is notoriously demanding; the GPU would render such scenes at slideshow frame rates, if it could run them at all.

The feature set is defined by its API support. DirectX 12 is supported at the 11_1 feature level, which means it can run DirectX 12 titles but with a reduced feature set compared to full DirectX 12 hardware. OpenGL 4.6 is supported, offering compatibility with a wide range of legacy and professional applications. Vulkan 1.2.170 is also available, which is a modern version of the API and allows for efficient multi-threaded rendering in supported games.

The lack of RT and tensor cores means the M365X cannot accelerate AI-based features like DLSS or denoising. It relies entirely on traditional rasterization. The 8 ROPs and 24 TMUs are the final arbiters of output quality; these units handle pixel blending and texture filtering, and their low counts further constrain the GPU to low resolutions and detail settings. The feature set is thus functional but bare-bones: it runs modern APIs at a basic level, but with none of the acceleration features that define contemporary GPUs.
