AMD Radeon R3E Mobile Graphics

AMD Radeon R3E Mobile Graphics is an end-of-life integrated graphics processor from AMD, built on the GCN 2.0 architecture and fabricated on a 28 nm process at GlobalFoundries. It targets the low-power mobile segment, drawing a 15 W TDP and relying entirely on system memory for its frame buffer, which makes its performance highly dependent on the host platform's memory configuration. The data shows a GPU that sits at the 50th percentile among all GPUs in the database, indicating a middling position that is typical for an IGP of its era, though its absolute performance is modest by contemporary standards.

Benchmark Performance

The benchmark results for the AMD Radeon R3E Mobile Graphics are notably sparse; the fact pack lists no individual benchmark scores and no nearest rivals for direct comparison. The average benchmark score is recorded as 0, which, combined with the 50th percentile ranking, suggests that the GPU's performance is essentially nominal within the database's context, likely reflecting its status as a low-end IGP with limited data points. Without specific scores or rival deltas, the analysis must rely on the architectural specifications to infer capability.

The GPU's compute throughput is anchored by its 128 shading units, 8 texture mapping units, and 4 raster output units. This configuration yields a pixel rate of 1.404 GPixel/s and a texture rate of 2.808 GTexel/s, while FP32 performance is rated at 89.86 GFLOPS. These figures are extremely low for any 3D workload, positioning the R3E as a solution for basic desktop tasks rather than gaming. In the absence of rival scores, the percentile data becomes the primary comparative tool: a 50th percentile ranking implies that half of all GPUs in the database outperform it, which is a sobering verdict for any potential gaming use case. The lack of nearestRivals entries means no exact percentage deltas can be cited, but the raw numbers indicate that even entry-level discrete GPUs from the same era would likely surpass it by a wide margin.

Power and Cooling

The AMD Radeon R3E Mobile Graphics is defined by its extremely low power envelope, with a TDP of just 15 W. This figure is critical because it allows the GPU to be integrated directly into a mobile platform without the need for active cooling or a dedicated power delivery system. As an IGP, it occupies a slot width of "IGP," meaning it is soldered onto the motherboard or embedded within the APU, and it requires no power connectors whatsoever—the power connector field is null. Consequently, there is no suggested PSU recommendation, as the GPU draws its power from the system's existing rails.

The 15 W TDP is the single most important power characteristic, as it dictates the thermal and electrical design of the host device. A 15 W envelope is typical for ultra-thin laptops and low-power mini PCs, where passive cooling is feasible. The lack of a dedicated power connector and the absence of a suggested PSU further underscore that this is not a component for user upgrades or custom builds; it is a fixed part of a system. The 28 nm process node, while mature for its time, contributes to the relatively modest power efficiency compared to newer nodes, but the low TDP ensures that thermal management is straightforward, even in fanless designs.

Ray Tracing and Feature Set

The AMD Radeon R3E Mobile Graphics does not include dedicated ray tracing cores or tensor cores; both fields are null. This is consistent with its GCN 2.0 architecture, which predates the hardware ray tracing acceleration found in later GPU generations. As a result, any ray-traced workloads would be handled entirely in software, which would be impractically slow given the GPU's limited compute throughput of 89.86 GFLOPS.

The feature set is instead defined by its API support. The GPU supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. DirectX 12 and Vulkan support are notable for an IGP of this vintage, as they allow the GPU to run modern API titles at low settings, though performance will be constrained by the hardware. OpenGL 4.6 provides compatibility with a wide range of desktop applications and legacy titles. The absence of tensor cores means no AI-accelerated features such as deep learning super sampling, and the lack of RT cores means no hardware-accelerated ray tracing; these are expected limitations for a 2015-era IGP.

Who Should Consider It

Given its 50th percentile ranking and minimal compute specs, the AMD Radeon R3E Mobile Graphics is only suitable for the most basic computing needs. The data indicates that it is not viable for modern gaming at any resolution; the 1.404 GPixel/s pixel rate and 89.86 GFLOPS FP32 performance are far below the thresholds needed for playable frame rates in 3D titles. Users should consider this GPU solely for light productivity, web browsing, office applications, and video playback, where its 15 W TDP and IGP form factor are assets.

For resolution and settings, the GPU is effectively limited to 720p or lower at reduced detail in very old or esports titles, though the lack of benchmark scores makes even this speculative. The system-dependent memory bandwidth is a further constraint; since the GPU shares system memory, performance will degrade significantly in dual-channel vs. single-channel configurations, though no specific numbers are available. The 50th percentile ranking, while neutral, suggests that it is not the worst GPU ever made, but it is far from a capable gaming solution. It is best suited for users who prioritize battery life and silent operation over any form of graphical performance.

Memory Subsystem

The memory subsystem of the AMD Radeon R3E Mobile Graphics is entirely dependent on the host system, with the VRAM size, type, and bus width all listed as "System Shared." This means the GPU does not have its own dedicated memory pool; instead, it borrows a portion of the system's RAM, which is typically DDR3 or DDR4 in the host platform. The memory bandwidth is listed as "System Dependent," indicating that performance scales with the speed and channel configuration of the system RAM.

This design has profound implications for high-resolution gaming. Because the GPU must access system memory over the shared bus, it competes with the CPU for bandwidth, leading to latency and throughput bottlenecks. At higher resolutions, the demand for memory bandwidth increases, and the R3E's lack of dedicated VRAM becomes a severe limitation. The absence of specific bandwidth figures means no exact numbers can be cited, but the "System Dependent" label implies that a system with fast dual-channel memory will yield better performance than one with slower single-channel memory. Even under ideal conditions, the 128 shading units and 4 ROPs will saturate the memory bus quickly, capping performance at low resolutions and detail settings.

How It Compares

The fact pack provides no nearest rivals for the AMD Radeon R3E Mobile Graphics, which is unusual and limits direct comparative analysis. The nearestRivals array is empty, meaning there are no named competing GPUs with scores or deltaPct values to reference. This is likely because the GPU's benchmark score is zero, placing it below the threshold for meaningful comparison in the database. In the absence of rival data, the only positional context is the 50th percentile ranking, which places it squarely in the middle of the database's GPU population, though this is likely skewed by the inclusion of many other low-power IGPs.

Without rival names, it is impossible to state specific percentage deltas. However, the architectural facts—128 shading units, 4 ROPs, and a 15 W TDP—suggest that it would be vastly outperformed by any discrete GPU from its era. The predecessor is listed as "TeraScale 3 IGP" and the successor as "GCN 3.0 IGP," indicating a generational progression within AMD's IGP lineup. The R3E's GCN 2.0 architecture is an incremental step over its predecessor, but the successor's newer architecture likely brings improvements in efficiency and feature support. The lack of rivals in the database, combined with a zero benchmark score, effectively means that the R3E Mobile Graphics occupies a niche position as a baseline for low-end mobile computing, with no direct competitors to measure against.
