About AMD Radeon R5 M315
The AMD Radeon R5 M315 is a GCN 3.0-based graphics processor from the R5 M300 series, manufactured on a 28 nm process at TSMC. It integrates 1,550 million transistors on a 125 mm² die, yielding a transistor density of 12.4M per mm². Released on May 4, 2015, the card is now end-of-life, with its successor listed as Polaris Mobile. The R5 M315 is positioned as an entry-level mobile GPU, but the specification sheet reveals several notable characteristics that define its capabilities and limitations.
Power and Cooling — TDP, PSU recommendation, connector requirements
The FACT PACK lists no TDP, no suggested PSU, and no power connector requirements for the R5 M315. This absence is itself informative: the card’s power draw is evidently low enough that it does not require an external power connector or a specific PSU rating. The only interface mentioned is PCIe 3.0 x8, which supplies power through the slot. Given the 28 nm process and the transistor count of 1,550 million, the card likely draws modest power, but no explicit figure is provided. The lack of a TDP also means that thermal design power cannot be used to infer cooling needs. In practice, this is a component designed for slim, low-power systems where space and heat dissipation are limited. The absence of any cooling-related specifications (slot width, dimensions) further suggests that the card is not intended for high-performance desktop configurations. The end-of-life status indicates that it is no longer in active production, but the power profile remains undefined in the official data.
Memory Subsystem — VRAM size/type, bus width, bandwidth and what it means for high resolutions
The R5 M315 comes with 2 GB of DDR3 memory on a 64-bit bus, delivering a bandwidth of 14.40 GB/s. The memory clock is 900 MHz, with an effective data rate of 1800 Mbps. This configuration is modest by any standard. The 64-bit bus width is particularly limiting: it halves the memory throughput compared to a 128-bit bus at the same clock speed. The DDR3 type is also slower than the GDDR5 used in higher-end cards of the same era. With 2 GB of VRAM, the card can handle basic textures but will struggle with high-resolution assets. For instance, at higher resolutions, the GPU must constantly swap textures in and out of memory, and the 14.40 GB/s bandwidth becomes a severe bottleneck. The pixel rate of 7.760 GPixel/s and texture rate of 23.28 GTexel/s indicate that the compute side is relatively weak, but the memory subsystem is even more constrained. In practical terms, the card is suited for 720p or low-detail 1080p gaming, but the data does not specify any resolution targets. The bandwidth is roughly one-fifth of what a contemporary mid-range card might offer, though no rival comparisons are available. The 1:1 FP16/FP32 ratio (745.0 GFLOPS for both) suggests that the card does not accelerate half-precision workloads differently, which is typical for GCN 3.0.
Ray Tracing and Feature Set — RT/tensor cores, API support from facts
The R5 M315 has no dedicated ray tracing cores (rtCores: null) and no tensor cores (tensorCores: null). This means that any ray tracing functionality would have to be implemented in software, which is impractical given the low compute throughput of 745.0 GFLOPS. The card does support DirectX 12 (feature level 12_0), OpenGL 4.6, and Vulkan 1.2.170. These API versions allow modern rendering techniques, but without hardware acceleration for ray tracing or AI-based features, the card is limited to traditional rasterization. The shading units number 384, with 24 texture mapping units and 8 ROPs. The pixel fill rate of 7.760 GPixel/s and texture fill rate of 23.28 GTexel/s are low, reinforcing the entry-level positioning. The architecture is GCN 3.0, which supports asynchronous compute and other features that DirectX 12 can leverage, but the raw hardware resources are small. The card’s API support is forward-looking for its time, yet the lack of RT and tensor cores means it cannot participate in the modern ray tracing or DLSS-style upscaling ecosystems.
How It Compares — position vs each nearest rival
The FACT PACK lists no nearest rivals (nearestRivals: []). Therefore, a direct comparison against specific competing GPUs cannot be made from the provided data. The percentileVsAllGpus field shows a value of 50, indicating that the card sits at the median of all GPUs in the database, but this percentile is based on unknown criteria and the average benchmark score is 0. Without rival data, the R5 M315’s relative performance must be inferred from its own specifications. Its 384 shading units and 745 GFLOPS of FP32 compute place it in the lower tier of GPUs released around 2015. The 2 GB VRAM and 14.40 GB/s bandwidth are similarly entry-level. In the absence of named rivals, the card’s position is best described as a basic mobile solution, likely outperforming integrated graphics but falling far short of discrete mid-range parts. The predecessor is listed as “Solar System” and the successor as “Polaris Mobile,” which suggests a generational progression, but no performance numbers are provided for either.
Benchmark Performance — analyze scores vs rivals with exact % deltas
The R5 M315 has an average benchmark score of 0, and no benchmark entries are listed in the FACT PACK. This means that no performance measurements have been recorded in the database. The percentileVsAllGpus is 50, but without a score, this percentile is not actionable. It could indicate that the card is exactly average in some ranking, but the zero score suggests that the ranking is based on hardware characteristics rather than actual tests. Consequently, there are no exact percentage deltas to report against rivals, because no rival scores exist. The only quantitative performance figures come from the theoretical specifications: 745.0 GFLOPS FP32, 23.28 GTexel/s texture rate, and 7.760 GPixel/s pixel rate. These numbers are modest, but without benchmark data, it is impossible to say how they translate into real-world frame rates. The absence of benchmark scores is a significant gap; the card’s performance can only be estimated from its architecture and clock speeds, which are also partially unspecified (base and boost clocks are null). The memory clock is the only clock given (900 MHz, 1800 Mbps effective). This lack of data means the card cannot be compared quantitatively to any other GPU.
Who Should Consider It — resolution/settings-based recommendations grounded in the scores
Given the specifications, the R5 M315 is best suited for low-resolution, low-detail gaming or as a basic display adapter for productivity tasks. The 2 GB VRAM and 14.40 GB/s bandwidth are sufficient for older or less demanding games at 720p or 1366x768 with low settings. At 1080p, the card would likely struggle with modern titles, especially those with high-resolution textures. The pixel rate of 7.760 GPixel/s and texture rate of 23.28 GTexel/s limit the fill-rate and texture-processing capabilities, which are critical for high-resolution rendering. The FP32 compute of 745.0 GFLOPS is also low, so compute-heavy effects like advanced physics or post-processing would be slow. The card supports DirectX 12 and Vulkan, which can improve efficiency in compatible games, but the hardware resources are minimal. The end-of-life status means that driver updates may be limited, but the API support (OpenGL 4.6, Vulkan 1.2.170) suggests it can run many older titles. Users who primarily need a GPU for office work, video playback, or light 2D applications could consider it, but for any serious gaming, the data indicates it is not a capable solution. The 1:1 FP16/FP32 ratio offers no advantage in mixed-precision workloads. In summary, the R5 M315 is a legacy entry-level component, and its suitability depends on very low performance expectations.
