AMD Radeon RX 6550M vs NVIDIA N1X 48SM Comparison

Head-to-Head Benchmarks

The benchmark database contains recorded scores for the AMD Radeon RX 6550M across two API tests, while the NVIDIA N1X 48SM currently has no recorded benchmark entries. This makes a direct numerical comparison impossible at this time, but the available data for the AMD part offers a clear positional reference.

The AMD Radeon RX 6550M delivers a Geekbench OpenCL score of 42536 and a Geekbench Vulkan score of 50867. Its average benchmark score across recorded tests is 46702. That places it at the 85th percentile among all GPUs in the database, a strong showing for a mobile integrated-class part. The Vulkan result runs roughly 19.6% higher than the OpenCL result, which indicates the architecture responds well to modern compute APIs with lower driver overhead.

Without any recorded scores for the NVIDIA N1X 48SM, its average benchmark score sits at 0 and its percentile ranking is 50. That percentile value, however, appears to reflect the absence of data rather than a measured performance level. The database treats unmeasured parts as median placeholders until actual results are submitted.

The AMD part's nearest rivals in the database underscore how tight the competition is at this performance tier. The Intel Arc A530M averages 46614, just 0.2% behind the RX 6550M. The AMD Radeon RX 5600M scores 46601, also 0.2% behind. The NVIDIA RTX A2000 trails by 1.4% with an average of 46043, and the NVIDIA RTX 5880 Ada Generation sits 1.6% back at 45972. These deltas are small enough that driver revisions or thermal conditions in a given laptop could flip the ordering between any two of these parts.

The practical takeaway from the measured data is that the RX 6550M occupies a narrow band where the top four nearest rivals are all within 1.6% of its average score. That is a tightly packed field. The RX 6550M leads that group, but only marginally, and the margin is well within run-to-run variance for most benchmark suites.

Architecture Differences

The two GPUs come from entirely different design lineages. The AMD Radeon RX 6550M uses the Navi 24 chip built on the RDNA 2.0 architecture, part of the Navi Mobile generation within the RX 6000M family. It is fabricated on a 6 nm process at TSMC. The NVIDIA N1X 48SM uses the GB20B chip based on the Blackwell 2.0 architecture, belonging to the Blackwell IGP (N1x) generation, and is built on a 5 nm process, also at TSMC.

The transistor counts diverge sharply. AMD lists 5,400 million transistors on a 107 mm² die, giving a transistor density of 50.5 million per mm². NVIDIA's transistor count is listed as unknown, but its die is substantially larger at 382 mm². No density figure is recorded for the NVIDIA part.

Clock behavior also differs in character. The AMD part runs a 2000 MHz base clock, a 2560 MHz game clock, and a 2840 MHz boost clock. The NVIDIA part uses a much lower 741 MHz base clock and a 2346 MHz boost clock, with no game clock specified. The AMD chip is designed to sustain high clocks across a relatively small shader array, while the NVIDIA chip leans on a far larger execution resource count running at lower clocks.

Memory architecture is another fundamental split. AMD pairs 4 GB of GDDR6 across a 64-bit bus, yielding 144.0 GB/s of bandwidth. NVIDIA pairs 128 GB of LPDDR5X across a 256-bit bus, yielding 273.2 GB/s. That is nearly double the bandwidth, and the capacity difference is enormous, but the two parts target different segments and system roles.

The API support records also differ. AMD lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. NVIDIA lists N/A for DirectX, OpenGL, and Vulkan. That N/A likely reflects incomplete database entries for a newly released part rather than a hardware limitation, given the Blackwell architecture's expected feature set.

Where Each One Wins

Based on recorded data, the AMD Radeon RX 6550M holds a clear advantage in measured benchmark presence. It has two completed tests in the database, an average score of 46702, and an 85th percentile standing. The NVIDIA N1X 48SM has no recorded tests, no average score, and a 50th percentile placeholder. In every measurable category, the AMD part wins by default because the data exists.

The RX 6550M also wins on clock speed. Its 2840 MHz boost clock and 2560 MHz game clock far exceed the NVIDIA part's 2346 MHz boost and 741 MHz base. For workloads that scale with clock frequency rather than raw execution width, the AMD part has the advantage.

The NVIDIA N1X 48SM wins on raw compute resources. It carries 6144 shading units, 384 texture mapping units, and 48 render output units, against AMD's 1024 shading units, 64 TMUs, and 32 ROPs. Its FP32 throughput of 28.83 TFLOPS is roughly 5 times the AMD part's 5.816 TFLOPS. Its texture rate of 900.9 GTexel/s is about 5 times AMD's 181.8 GTexel/s. Its pixel rate of 112.6 GPixel/s beats AMD's 90.88 GPixel/s by roughly 24%. These are large resource advantages, but without benchmark results, they remain theoretical.

The NVIDIA part also leads on memory capacity and bandwidth. Its 128 GB of LPDDR5X against AMD's 4 GB of GDDR6 is a generational gap in capacity. Its 273.2 GB/s bandwidth is 89.7% higher than AMD's 144.0 GB/s. For large working sets or memory-intensive compute, the NVIDIA part has a structural edge.

The NVIDIA part includes 48 RT cores and 192 tensor cores, while AMD includes 16 RT cores and no tensor cores. For ray tracing and tensor-accelerated workloads, the NVIDIA architecture has dedicated hardware that AMD lacks entirely on the tensor side.
