AMD Radeon R5E Mobile Graphics

Benchmark Performance

The AMD Radeon R5E Mobile Graphics occupies a unique position in the database: it sits at the 50th percentile of all GPUs tracked, yet carries an average benchmark score of zero. This paradox stems from its nature as an integrated graphics processor (IGP) with no standalone benchmark submissions; the percentile ranking is derived from its architectural class and expected performance envelope rather than measured results. The data indicates a part designed for basic computing tasks, not for demanding graphical workloads.

With 128 shading units, 8 texture mapping units, and only 4 render output units, the R5E's computational throughput is strictly limited. The FP32 performance of 204.8 GFLOPS places it firmly in the entry-level segment, a figure that translates to roughly 0.2 teraflops of single-precision compute — a number dwarfed by even modest discrete GPUs from the same era. The pixel rate of 3.200 GPixel/s and texture rate of 6.400 GTexel/s further confirm this positioning; these are figures suitable for 2D desktop rendering, light video playback, and casual gaming at low resolutions and detail settings.

The memory subsystem is entirely system-dependent. The R5E uses "System Shared" memory with a bus width also listed as "System Shared," and bandwidth is described as "System Dependent." This means the IGP borrows from the host system's RAM, and performance scales with the memory configuration of the laptop or portable device in which it resides. Faster dual-channel DDR3 memory would yield better results than single-channel configurations, though the data does not specify which memory standards are supported. The lack of dedicated VRAM is the single largest bottleneck for this chip.

Considering the 28 nm process node from GlobalFoundries, the R5E packs 930 million transistors into a 107 mm² die, yielding a transistor density of 8.7 million transistors per square millimeter. This is a modest density figure by modern standards, reflecting the 2014-era design. The architecture is GCN 2.0, specifically the Mullins Mobile variant, which was AMD's low-power IGP solution for thin-and-light laptops and tablets. The "Mobile" designation in the name is critical — this is not a desktop part, and its 15 W TDP confirms its ultra-low-power intent.

How It Compares

The FACT PACK lists no nearest rivals for this GPU, which is telling. In the benchmark database, the R5E exists in a category of one — there are no direct comparison points with percentage deltas to report. This absence suggests that the database either lacks sufficient benchmark data for this IGP or that it is so far removed from other tracked GPUs that no meaningful comparisons can be drawn. The 50th percentile ranking, however, implies it sits exactly in the middle of all GPUs ever tracked, which is surprising given its modest specifications.

Without nearestRivals data, the R5E must be evaluated on its own architectural merits. Its predecessor is the TeraScale 3 IGP, and its successor is the GCN 3.0 IGP, indicating a clear generational progression within AMD's integrated lineup. The jump from TeraScale to GCN 2.0 brought significant architectural improvements, including better compute performance and more efficient power management. The R5E's 128 shading units represent a doubling over typical TeraScale 3 IGPs, though the 4 ROPs remain a persistent bottleneck for fill-rate-bound workloads.

The lack of any benchmark scores in the database — the avgBenchmarkScore field is exactly 0 — means that the 50th percentile is an algorithmic placement rather than a measured one. This is a GPU that has never been benchmarked in the database's history. For a part that is now end-of-life (production status confirms this), the absence of data is not surprising; most users of such an IGP would not run synthetic benchmarks, and the GPU's capabilities are so far below modern standards that it has been largely forgotten.

Ray Tracing and Feature Set

There are no ray tracing cores and no tensor cores listed for the R5E. This is expected for a 2014-era integrated GPU; hardware-accelerated ray tracing did not appear in mainstream GPUs until several years later, and even then only in high-end discrete parts. The R5E relies entirely on traditional rasterization techniques, and any ray tracing would have to be performed on the 128 shading units via compute shaders — an approach that would be impractically slow given the 204.8 GFLOPS FP32 throughput.

The API support, however, is more generous than the hardware might suggest. The R5E supports DirectX 12 (feature level 12_0), which means it can run games and applications built for Microsoft's latest graphics API at the time of its release. DirectX 12's low-level access to hardware can help mitigate some of the R5E's performance limitations by reducing driver overhead, though the raw compute power is still the binding constraint. OpenGL 4.6 is also supported, ensuring compatibility with a wide range of cross-platform applications and emulators.

Vulkan support is listed at version 1.2.170, which is a relatively recent version of the API. This is noteworthy for an end-of-life product, as it suggests AMD has maintained driver support for this IGP well beyond its production window. Vulkan's explicit control over GPU resources can benefit the R5E in workloads that are bottlenecked by CPU overhead, though again the fundamental performance ceiling remains low. The combination of DirectX 12_0, OpenGL 4.6, and Vulkan 1.2.170 gives the R5E a surprisingly modern feature set for its age, though the hardware cannot fully exploit these APIs' advanced features.

A: The R5E is manufactured on a 28 nm process node by GlobalFoundries. The die contains 930 million transistors on a 107 mm² die, for a transistor density of 8.7 million transistors per square millimeter.

Power and Cooling

The R5E has a thermal design power (TDP) of 15 W, which is exceptionally low and confirms its intended use in thin-and-light portable devices. This TDP figure is the total power budget for the entire GPU, including the shading units, texture units, and ROPs, as well as the memory controller that interfaces with system RAM. A 15 W TDP means the R5E can be cooled passively in many designs, or with a single small fan in more performance-oriented laptops. The "IGP" slot width indicates that this is not a discrete card; it is soldered onto the motherboard or integrated into the APU package.

The FACT PACK lists no power connectors and no suggested PSU for this GPU. This is consistent with its integrated nature — there is no external power delivery requirement, as the GPU draws its power from the motherboard's VRM circuitry, which is shared with the CPU. For a system builder or user considering a device with this IGP, the power supply requirements are dictated by the entire system, not the GPU. The lack of a suggested PSU figure in the database indicates that the R5E does not impose any additional power supply constraints beyond what the host laptop or tablet already provides.

The display outputs are listed as "Portable Device Dependent," meaning the specific video output ports (HDMI, DisplayPort, VGA, etc.) vary by the laptop or tablet design. This is another consequence of the IGP form factor — the board designer decides which outputs to route from the GPU. The bus interface is also IGP, confirming that the R5E communicates with the rest of the system via the internal bus rather than a PCIe slot. For cooling, the 15 W TDP can be managed with a heatsink and fan combination typical of ultraportable laptops, or in some cases with a heat pipe connected to the system's main cooling solution. The low power draw also means that sustained performance is unlikely to be thermally throttled in most well-designed chassis, though the GPU's raw performance ceiling is reached long before thermal limits become a concern.
