AMD Radeon RX 6550S vs AMD Radeon RX 9050 Comparison

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results for the AMD Radeon RX 6550S and the AMD Radeon RX 9050. Neither GPU has an average benchmark score, and the winsA and winsB fields are both zero. This means the comparison must rely on the recorded architectural and specification data rather than direct performance measurements.

The most significant performance indicator is the FP32 compute throughput. The RX 9050 delivers 10.65 TFLOPS, while the RX 6550S delivers 4.915 TFLOPS. This represents a 116.7% advantage for the RX 9050 in raw single-precision floating-point work. The RX 9050 also achieves a texture rate of 166.4 GTexel/s, compared to 153.6 GTexel/s for the RX 6550S, an 8.3% lead. In pixel throughput, the RX 9050 posts 166.4 GPixel/s versus 76.80 GPixel/s for the RX 6550S, a 116.7% difference that directly reflects the RX 9050's doubled ROP count.

Memory bandwidth heavily favors the RX 9050. The RX 9050 offers 288.0 GB/s over a 128 bit bus, while the RX 6550S provides 128.0 GB/s over a 64 bit bus. The RX 9050 therefore has a 125.0% bandwidth advantage, which is critical for texture-heavy workloads and higher resolutions. The RX 9050 also doubles the memory capacity at 8 GB versus 4 GB.

Half-precision performance tells a different story about architecture. The RX 6550S reaches 9.830 TFLOPS FP16 using a 2:1 rate, while the RX 9050 reaches 10.65 TFLOPS FP16 at a 1:1 rate. Despite the RX 9050's higher FP32 baseline, its FP16 output is only 8.3% higher than the RX 6550S, because the RX 6550S uses rate-doubling hardware. In FP16, the RX 9050 does not accelerate beyond its FP32 rate, whereas the RX 6550S effectively doubles its throughput.

The RX 9050's boost clock is 2600 MHz, 8.3% higher than the RX 6550S boost of 2400 MHz. The RX 6550S counters with a much higher base clock at 2000 MHz versus 1330 MHz, a 50.4% difference. Game clocks also favor the RX 6550S at 2170 MHz versus 1920 MHz, a 13.0% margin. The RX 9050 compensates with a significantly larger transistor budget: 29,700 million transistors versus 5,400 million, a 450% increase, packed into a 199 mm² die versus 107 mm².

Both GPUs share identical shading unit counts at 1024 and TMU counts at 64. Both also feature 16 ray accelerators, meaning the ray tracing hardware count is equal. The RX 9050 doubles the ROP count to 64 from 32. The RX 9050's pixel rate advantage of 116.7% matches its ROP doubling, while its texture rate advantage is muted because TMU counts are equal and the boost clock difference is modest.

The RX 9050 operates at 10.65 TFLOPS FP32 with a 92 W TDP, delivering 115.8 GFLOPS per watt. The RX 6550S operates at 4.915 TFLOPS with a 50 W TDP, delivering 98.3 GFLOPS per watt. The RX 9050 is therefore 17.8% more efficient in FP32 throughput per watt, despite its much higher absolute power draw.

Memory clock speeds differ as well. The RX 6550S runs memory at 2000 MHz with 16 Gbps effective, while the RX 9050 runs at 2250 MHz with 18 Gbps effective. The RX 9050's memory clock is 12.5% higher, and its effective data rate is 12.5% higher. Combined with the double-wide bus, this yields the 125.0% bandwidth advantage noted earlier.

The RX 9050 supports PCIe 5.0 x16, while the RX 6550S uses PCIe 4.0 x4. The RX 9050's interface offers 4 times the lane count and a newer generation, which matters for data transfer between CPU and GPU. The RX 6550S is an integrated graphics package with an IGP slot width and no power connectors, whereas the RX 9050 is a dual-slot card requiring a single 8-pin connector and a 250 W suggested power supply.

The Verdict

The recorded data indicates the AMD Radeon RX 9050 is the stronger GPU in nearly every absolute metric. It delivers 116.7% higher FP32 throughput, 116.7% higher pixel rate, 125.0% higher memory bandwidth, and double the memory capacity. Its 8.3% texture rate advantage is smaller but still positive. For any workload limited by compute, pixel fill, or memory bandwidth, the RX 9050 is the clear choice based on the specification sheet.

The RX 6550S does hold advantages in clock behavior. Its base clock is 50.4% higher, and its game clock is 13.0% higher. It also achieves 17.8% better FP32 efficiency per watt when comparing 4.915 TFLOPS at 50 W against 10.65 TFLOPS at 92 W. Systems with strict thermal or power constraints would favor the RX 6550S, which draws 42 W less and requires no external power connector.

The FP16 comparison is notable. The RX 6550S reaches 9.830 TFLOPS via a 2:1 rate, nearly matching the RX 9050's 10.65 TFLOPS at a 1:1 rate. In FP16-heavy applications, the two GPUs are much closer than the FP32 gap suggests, with the RX 9050 leading by only 8.3%. The RX 9050's ray accelerator count matches the RX 6550S at 16, so no ray tracing hardware advantage exists between them.

The RX 9050's 4 nm process and RDNA 4.0 architecture provide a denser design at 149.2M transistors per mm² versus 50.5M for the RX 6550S. The RX 9050 uses 29,700 million transistors on a 199 mm² die, while the RX 6550S uses 5,400 million on a 107 mm² die. This is a generational leap in complexity, but it comes with higher power requirements and a dual-slot form factor.

The RX 6550S suits portable or integrated systems where the IGP slot width, 50 W TDP, and no power connector are mandatory. The RX 9050 suits desktop builds with room for a dual-slot card, an 8-pin connector, and a suggested power supply of 250 W. Neither GPU has recorded benchmark scores, so the verdict rests entirely on the specification data, which consistently favors the RX 9050 for raw performance and the RX 6550S for power efficiency and clock stability.

Architecture Differences

The RX 6550S uses the Navi 24 chip built on RDNA 2.0 architecture, while the RX 9050 uses the Navi 44 chip built on RDNA 4.0. The RX 6550S belongs to the Navi Mobile (RX 6000M) generation, and the RX 9050 belongs to the Navi IV (RX 9000) generation. The RX 9050's predecessor is listed as Navi III, while the RX 6550S's predecessor is Polaris Mobile.

The manufacturing process differs by two nodes. The RX 6550S uses a 6 nm process at TSMC, while the RX 9050 uses a 4 nm process at the same foundry. Transistor density reflects this: the RX 9050 packs 149.2M transistors per mm², versus 50.5M for the RX 6550S. Total transistor count is 29,700 million for the RX 9050 versus 5,400 million for the RX 6550S, and die size is 199 mm² versus 107 mm².

The FP16 implementation differs. The RX 6550S achieves 9.830 TFLOPS FP16 through a 2:1 rate, meaning it doubles its FP32 throughput for half-precision work. The RX 9050 achieves 10.65 TFLOPS FP16 at a 1:1 rate, meaning its FP16 output equals its FP32 output with no rate doubling. This architectural choice explains why the FP16 gap is only 8.3% despite the large FP32 gap.

Both architectures support the same API set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both have 16 ray accelerators, but the RX 9050 doubles the ROP count to 64. Neither GPU lists tensor cores, so no dedicated AI acceleration hardware is recorded for either.

The RX 9050's pixel rate of 166.4 GPixel/s exactly matches its texture rate of 166.4 GTexel/s. The RX 6550S has a pixel rate of 76.80 GPixel/s and a texture rate of 153.6 GTexel/s. The RX 9050's balanced rates stem from its higher boost clock and doubled ROPs, while the RX 6550S's texture-heavy profile reflects its 64 TMUs at higher clocks.

Specification Differences

The RX 9050 uses an 8 GB GDDR6 memory configuration with a 128 bit bus and 288.0 GB/s bandwidth. The RX 6550S uses 4 GB GDDR6 with a 64 bit bus and 128.0 GB/s bandwidth. Effective memory speed is 18 Gbps for the RX 9050 versus 16 Gbps for the RX 6550S.

The RX 9050 has a base clock of 1330 MHz, a boost clock of 2600 MHz, and a game clock of 1920 MHz. The RX 6550S has a base clock of 2000 MHz, a boost clock of 2400 MHz, and a game clock of 2170 MHz. The RX 9050 has the higher boost, while the RX 6550S has the higher base and game clocks.

Power and form factor differ substantially. The RX 9050 has a 92 W TDP, dual-slot width, one 8-pin power connector, and a suggested power supply of 250 W. The RX 6550S has a 50 W TDP, IGP slot width, and no power connectors. The RX 9050 uses a PCIe 5.0 x16 bus interface, while the RX 6550S uses PCIe 4.0 x4.

Display outputs also differ. The RX 9050 provides 1x HDMI 2.1b and 2x DisplayPort 2.1a. The RX 6550S lists display outputs as portable device dependent, meaning its outputs vary by the host device. The RX 9050 is a discrete dual-slot card, while the RX 6550S is integrated into a portable platform.

Release dates are separated by several years. The RX 6550S was released on 2023-01-03, and the RX 9050 was released on 2026-07-27. Both are listed as active in production. Neither GPU has a recorded launch MSRP, and neither has a recorded successor.
