AMD Radeon RX 550 Mobile

The AMD Radeon RX 550 Mobile is a 14 nm mobile graphics processor built by GlobalFoundries for the Polaris Mobile generation, using the GCN 4.0 architecture on the Lexa chip. The die measures 103 mm² and packs 2,200 million transistors, yielding a transistor density of 21.4M per mm². It carries 640 shading units, 40 texture mapping units, and 16 render output units, with a base clock of 1100 MHz and a boost clock of 1287 MHz. Memory consists of 2 GB of GDDR5 on a 128-bit bus, running at 1500 MHz with 6 Gbps effective throughput and 96.00 GB/s of bandwidth. The part is rated at a 50 W TDP, uses no external power connectors, and connects over PCIe 3.0 x8. In the benchmark database, it holds the 50th percentile among all GPUs, though its average benchmark score is recorded as 0 and no rival entries are listed.

Benchmark Performance

The benchmark data for this part is unusually sparse. The fact pack lists no individual benchmark scores, and the average benchmark score is recorded as 0. The only positional metric available is the percentile ranking: 50th among all GPUs in the database. This places the RX 550 Mobile at the exact median of the GPU population, meaning an equal number of entries sit above and below it. However, because the nearestRivals field is empty, there are no percentage deltas to report against specific competing parts. The data does not support any claim of being ahead of or behind a named rival by any amount.

Without measured benchmark results, the quantitative performance indicators are the fixed-function rates and compute throughput derived from the clock and unit counts. The pixel rate is 20.59 GPixel/s, the texture rate is 51.48 GTexel/s, and the FP32 throughput is 1.647 TFLOPS. The FP16 rate is identical at 1.647 TFLOPS, indicating a 1:1 ratio between FP16 and FP32 execution. These figures are the only concrete performance numbers in the record. The 640 shading units at a boost clock of 1287 MHz produce the 1.647 TFLOPS figure, while the 40 TMUs and 16 ROPs set the texture and pixel rates respectively. The memory side delivers 96.00 GB/s across a 128-bit bus, which is the bandwidth ceiling for any workload that saturates the frame buffer.

The absence of benchmark entries means the percentile rank of 50 cannot be cross-referenced against any actual score. It is a positional statement within the database, not a measured result. In practical terms, the data shows a part that is statistically average in the overall GPU landscape, but with no direct measurements to confirm or refine that position. The theoretical rates suggest a modest mobile part, but without benchmark scores, that interpretation rests on the specification sheet alone.

Who Should Consider It

The recorded specifications point toward a mobile GPU intended for lightweight graphics workloads. The 2 GB GDDR5 frame buffer, 128-bit memory bus, and 96.00 GB/s bandwidth define a memory subsystem that is small by current standards. The 640 shading units and 1.647 TFLOPS FP32 throughput place the compute capacity in a similar range. These numbers, taken together, indicate a part that can handle modest rendering demands but is not positioned for high-end or high-resolution work. The display outputs are described as "Portable Device Dependent," which means the actual output configuration is determined by the host laptop or portable device, not by the GPU itself.

The 50 W TDP and the IGP slot width are consistent with an integrated or semi-integrated mobile solution. The slot width of IGP suggests that the GPU is mounted in an integrated graphics package rather than a discrete expansion card. This reinforces the idea that the target system is a thin or light portable device where power and space are constrained. The lack of external power connectors further supports this, as the GPU draws its power through the system rather than through a dedicated supply line.

For users, the data implies that this GPU is best suited to everyday tasks and lighter graphics loads. The 2 GB memory capacity is a hard ceiling for texture and geometry data, and the 96.00 GB/s bandwidth limits how quickly data can be fed to the 640 shading units. The 50th percentile ranking suggests that, within the database's population, it is neither a standout performer nor a laggard. The end-of-life production status means that new units are no longer being manufactured, so consideration is limited to existing systems or refurbished parts.

Ray Tracing and Feature Set

The fact pack lists no RT cores and no tensor cores for the RX 550 Mobile. This is a definitive absence: the hardware does not include dedicated ray tracing units or tensor processing units. Consequently, any ray tracing or AI-accelerated workloads would not have dedicated hardware support within this GPU. The architecture is GCN 4.0, which predates the integration of such units in AMD's product line. The feature set is instead defined by the API support: DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3.

The DirectX 12 support is at feature level 12_0, which is the baseline feature level for DirectX 12. OpenGL 4.6 and Vulkan 1.3 provide modern graphics API access. The memory is GDDR5, and the memory clock is 1500 MHz with 6 Gbps effective throughput. The bus interface is PCIe 3.0 x8, which provides a narrower link than a full x16 slot but is sufficient for the bandwidth demands of this part. The display outputs are portable-device-dependent, so the actual connectors are not specified in the data.

The absence of RT and tensor cores is the most notable feature-set limitation. The GPU's compute capability, measured at 1.647 TFLOPS for both FP32 and FP16, is available for general-purpose shader work, but there is no hardware acceleration for the specialized paths that RT cores and tensor cores serve. The API list shows that the part can expose Vulkan 1.3 and DirectX 12_0 features to software, but the hardware itself lacks those specialized units.

Power and Cooling

The RX 550 Mobile is rated at a 50 W TDP. This is the only power figure in the fact pack, and it defines the thermal design envelope. The slot width is listed as IGP, indicating an integrated graphics package. There are no power connectors listed, which means the GPU does not require external PCIe power cables. The suggested PSU field is null, so the data provides no power supply recommendation.

The 50 W TDP is a modest figure, and the absence of power connectors simplifies system integration. The GPU draws power through the system's existing power delivery, which is typical for an integrated mobile part. The PCIe 3.0 x8 interface carries both data and, in an integrated context, power. The lack of a suggested PSU reflects the fact that this is not a discrete card that a user would install; it is built into a portable device. The cooling solution is likewise not specified, but the 50 W envelope is low enough that a capable cooling solution is implied by the form factor. The production status is end-of-life, so the part is no longer in active production.

How It Compares

The fact pack's nearestRivals field is empty, so there are no named competitors with scores or percentage deltas to analyze. This is a notable gap in the data. The only comparative metric is the 50th percentile ranking among all GPUs in the database. That figure places the RX 550 Mobile at the median of the entire GPU population, but without rival entries, it is impossible to say how it stacks up against any specific part. The predecessor is listed as "Gem System" and the successor as "Navi Mobile," which provides generational context but no performance numbers.

Because no rival data is present, no percentage deltas can be computed. The data does not support statements like "ahead of X by Y%." The percentile of 50 is the sole positional reference. It indicates that, in the database's aggregate ranking, this GPU sits in the middle. The average benchmark score of 0 further complicates comparison, as there are no measured results to weigh against other parts. The theoretical specifications — 1.647 TFLOPS, 96.00 GB/s bandwidth, 2 GB memory — are the only quantitative basis for positioning, and they describe a modest mobile part. The comparison section is therefore limited to noting the absence of rival data and the median percentile placement.
