AMD Radeon RX 6550M vs NVIDIA N1 20SM Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison because the two parts are measured on different footing. The AMD Radeon RX 6550M has two benchmark results in the database, while the NVIDIA N1 20SM has zero recorded benchmark scores. This makes a direct head-to-head numeric comparison impossible. The RX 6550M delivers an average benchmark score of 46,702, placing it in the 85th percentile of all GPUs. The N1 20SM, by contrast, shows an average score of 0 and sits in the 50th percentile, which reflects the absence of measured performance data rather than actual hardware capability.

The RX 6550M's nearest rivals provide context for its standing. The Intel Arc A530M scores 46,614, a delta of 0.2 percent, meaning the RX 6550M is essentially tied with it. The AMD Radeon RX 5600M scores 46,601, also a 0.2 percent delta. The NVIDIA RTX A2000 scores 46,043, putting it 1.4 percent behind the RX 6550M. The NVIDIA RTX 5880 Ada Generation scores 45,972, trailing by 1.6 percent. These margins are small, indicating that the RX 6550M sits in a tightly packed performance band. The recorded data shows no head-to-head benchmark entries and no wins for either part.

For the N1 20SM, there are no nearest rivals listed and no benchmark scores to interpret. The database records a 50th percentile position, which is a neutral placement when no measurements exist. The absence of data means any performance comparison against the RX 6550M would be speculative. The RX 6550M's OpenCL score of 42,536 and Vulkan score of 50,867 demonstrate measurable strengths in compute workloads. The N1 20SM has no equivalent figures.

The RX 6550M's FP32 throughput of 5.816 TFLOPS and texture rate of 181.8 GTexel/s provide concrete computational output. The N1 20SM's FP32 throughput of 12.01 TFLOPS and texture rate of 375.4 GTexel/s are recorded specifications, but without benchmark validation, these numbers represent theoretical capability rather than observed performance. The data confirms the RX 6550M as a measured performer, while the N1 20SM remains an unverified entry.

Architecture Differences

The two parts come from fundamentally different design lineages. The AMD Radeon RX 6550M uses the Navi 24 chip based on RDNA 2.0 architecture, manufactured on a 6 nm process at TSMC. It belongs to the Navi Mobile generation within the RX 6000M series. The NVIDIA N1 20SM uses the GB20B chip based on Blackwell 2.0 architecture, also built at TSMC but on a 5 nm node. It belongs to the Blackwell IGP (N1x) generation.

The process node difference is meaningful. The RX 6550M uses 6 nm, while the N1 20SM uses 5 nm. The RX 6550M integrates 5,400 million transistors on a 107 mm² die, yielding a transistor density of 50.5 million per mm². The N1 20SM has a die size of 382 mm², which is substantially larger, though its transistor count is recorded as unknown. The larger die area for the N1 20SM suggests a more complex design, but the database does not specify its transistor density.

Memory architecture diverges sharply. The RX 6550M uses 4 GB of GDDR6 on a 64-bit bus, delivering 144.0 GB/s of bandwidth. The N1 20SM uses 128 GB of LPDDR5X on a 256-bit bus, delivering 273.2 GB/s. The N1 20SM has 32 times the memory capacity and nearly double the bandwidth. The memory clock also differs: the RX 6550M runs at 2250 MHz with 18 Gbps effective, while the N1 20SM runs at 1067 MHz with 8.5 Gbps effective.

The compute unit layouts are distinct. The RX 6550M has 1024 shading units, 64 texture mapping units, 32 render output units, and 16 ray tracing cores. It has no tensor cores. The N1 20SM has 2560 shading units, 160 TMUs, 24 ROPs, 20 RT cores, and 80 tensor cores. The N1 20SM offers 2.5 times the shading units and 2.5 times the TMUs, but fewer ROPs. The RX 6550M has a higher pixel rate at 90.88 GPixel/s versus 56.30 GPixel/s for the N1 20SM, despite having more ROPs on paper.

API support also separates them. The RX 6550M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 20SM lists N/A for DirectX, OpenGL, and Vulkan, indicating no recorded API compatibility. The RX 6550M uses a PCIe 4.0 x4 bus interface, while the N1 20SM uses PCIe 5.0 x16, a faster and wider connection. Both parts are IGP slot width with no power connectors. The RX 6550M has an 80 W TDP, while the N1 20SM's TDP is unknown. Display outputs differ: the RX 6550M is portable device dependent, while the N1 20SM has 1x HDMI.

Where Each One Wins

The RX 6550M wins in measured performance. Its average benchmark score of 46,702 places it in the 85th percentile, and its OpenCL and Vulkan scores of 42,536 and 50,867 respectively confirm real-world compute capability. The RX 6550M also wins on pixel throughput, delivering 90.88 GPixel/s compared to 56.30 GPixel/s for the N1 20SM. This higher pixel rate suggests stronger fill-rate performance for rasterization tasks. The RX 6550M also has a higher base clock of 2000 MHz versus 741 MHz for the N1 20SM, and a higher boost clock of 2840 MHz versus 2346 MHz.

The N1 20SM wins on raw specification sheet advantages. Its FP32 throughput of 12.01 TFLOPS is more than double the RX 6550M's 5.816 TFLOPS. Its texture rate of 375.4 GTexel/s exceeds the RX 6550M's 181.8 GTexel/s by a wide margin. The N1 20SM's 128 GB of LPDDR5X memory dwarfs the RX 6550M's 4 GB, and its 273.2 GB/s bandwidth nearly doubles the RX 6550M's 144.0 GB/s. The N1 20SM also offers 2560 shading units versus 1024, 160 TMUs versus 64, and 80 tensor cores versus none. Its PCIe 5.0 x16 interface provides substantially more system bandwidth than the RX 6550M's PCIe 4.0 x4.

The N1 20SM wins on architectural modernity. It uses a 5 nm process versus 6 nm, and its Blackwell 2.0 architecture is newer than RDNA 2.0. The N1 20SM's 20 RT cores and 80 tensor cores give it dedicated hardware for ray tracing and AI workloads, while the RX 6550M has only 16 RT cores and no tensor cores. The N1 20SM's 382 mm² die is significantly larger, suggesting a more capable overall design.

However, wins on paper do not translate to recorded wins in the database. The head-to-head benchmark table is empty, and neither part has a wins count. The RX 6550M has benchmark data to support its position, while the N1 20SM does not. The RX 6550M's measured scores place it ahead of several NVIDIA workstation parts, including the RTX A2000 by 1.4 percent and the RTX 5880 Ada Generation by 1.6 percent. The N1 20SM has no comparable data.

The Verdict

The data supports choosing the AMD Radeon RX 6550M for anyone requiring verified performance. Its average benchmark score of 46,702 and 85th percentile placement confirm it as a functional, measured GPU. The RX 6550M's OpenCL score of 42,536 and Vulkan score of 50,867 provide concrete evidence of compute capability. Its nearest rivals, including the Intel Arc A530M and AMD Radeon RX 5600M, are within 0.2 percent, showing the RX 6550M competes effectively in its class.

The NVIDIA N1 20SM cannot be recommended based on recorded data. It has no benchmark scores, no nearest rivals, and an average score of 0. While its specification sheet shows impressive numbers, including 12.01 TFLOPS FP32, 128 GB of memory, and 80 tensor cores, the database contains no measurements to verify these capabilities. The 50th percentile placement reflects missing data, not actual performance.

For rasterization-focused workloads, the RX 6550M's higher pixel rate of 90.88 GPixel/s and higher clock speeds provide a measured advantage. For tasks requiring massive memory capacity or tensor core acceleration, the N1 20SM's specifications suggest theoretical strengths, but without benchmark validation, these remain unconfirmed. The RX 6550M also has the advantage of API support, with DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 all recorded, while the N1 20SM lists N/A for all three.

The release dates differ as well. The RX 6550M was released on January 3, 2023, and is currently active. The N1 20SM has a release date of May 31, 2026, meaning it is a future product. The RX 6550M is available now with proven performance, while the N1 20SM's capabilities remain entirely unmeasured. The data indicates the RX 6550M is the safer choice for immediate use, while the N1 20SM should be evaluated only after benchmark results become available.
