AMD Radeon 880M vs NVIDIA N1X 48SM Comparison

AMD Radeon 880M and NVIDIA N1X 48SM represent two distinct approaches to integrated graphics, separated by nearly two years of architectural evolution. The database records no direct head-to-head benchmark comparisons between these two parts, so the analysis below relies on their respective specification sheets, standalone benchmark runs, and the relative performance context provided by the AMD part's nearest rivals. The AMD Radeon 880M has a recorded average benchmark score of 8436, placing it in the 43rd percentile of all GPUs. The NVIDIA N1X 48SM has no recorded benchmark scores, an average score of zero, and a 50th percentile placement, which reflects its status as a newer, unmeasured part rather than a performance parity claim.

Where Each One Wins

The AMD Radeon 880M wins in every category where recorded data exists, simply because the NVIDIA N1X 48SM has no benchmark entries in the database. The 880M shows its strongest standing in legacy and compute-oriented workloads. In Passmark's DirectX 9 test, it scores 97, which is its highest individual Passmark API result, indicating strong performance in older DirectX titles. Its Passmark G3D score of 7615 is the dominant graphics result, while the Passmark G2D score of 969 covers 2D and user interface workloads. For compute, the Geekbench OpenCL score of 31285 and Vulkan score of 40006 demonstrate that the 880M handles both general-purpose compute and modern graphics APIs effectively. The 3DMark Steel Nomad DX12 score of 535, while modest in absolute terms, confirms DirectX 12 functionality.

The NVIDIA N1X 48SM wins on paper in raw hardware capability, though without benchmark data these are theoretical advantages. Its 28.83 TFLOPS of FP32 compute is over six times the 880M's 4.454 TFLOPS. Its texture rate of 900.9 GTexel/s dwarfs the 880M's 139.2 GTexel/s, and its pixel rate of 112.6 GPixel/s exceeds the 880M's 46.40 GPixel/s. These figures suggest the N1X 48SM is designed for substantially heavier graphics workloads, but the database cannot confirm real-world performance until benchmark results are recorded.

Architecture Differences

The two GPUs come from different manufacturers and use different process nodes and architectures. The AMD Radeon 880M uses the Strix Point chip built on RDNA 3.5 architecture, manufactured on a 4 nm process at TSMC. It belongs to the Navi III IGP generation for Strix Point Mobile. The NVIDIA N1X 48SM uses the GB20B chip on Blackwell 2.0 architecture, manufactured on a 5 nm process, also at TSMC. It belongs to the Blackwell IGP generation for N1x. The 880M integrates 34,000 million transistors on a 233 mm² die, giving a transistor density of 145.9 million per square millimeter. The N1X 48SM's transistor count is listed as unknown, but its die size is 382 mm², which is significantly larger than the 880M's die.

The compute resources differ sharply. The 880M has 768 shading units, 48 texture mapping units, 16 raster operation units, 12 ray tracing cores, and no tensor cores. The N1X 48SM has 6144 shading units, 384 TMUs, 48 ROPs, 48 RT cores, and 192 tensor cores. This gives the N1X 48SM eight times the shading units, eight times the TMUs, and three times the ROPs of the 880M. The N1X 48SM also includes dedicated tensor cores, which the 880M lacks entirely. Both parts deliver FP16 at a 1:1 ratio with FP32, meaning neither has a half-rate FP16 path.

Memory architecture is another major divergence. The 880M uses system shared memory, with the size, type, bus width, and bandwidth all marked as system dependent. The N1X 48SM has dedicated memory specifications: 128 GB of LPDDR5X on a 256-bit bus, with 273.2 GB/s of bandwidth and a memory clock of 1067 MHz, 8.5 Gbps effective. This is a fundamental difference. The N1X 48SM does not rely on the host system's memory pool, while the 880M's performance will scale with the system's memory configuration.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for the AMD Radeon 880M versus the NVIDIA N1X 48SM, so no direct score comparisons can be made. The 880M's standalone results, however, provide context for its performance tier. Its average benchmark score of 8436 places it near several discrete mobile GPUs. The closest rival is the NVIDIA GeForce GTX 675MX with an average score of 8427, which is 0.1% behind the 880M. The NVIDIA GeForce MX330 scores 8458, 0.3% ahead. The AMD Radeon HD 8870M scores 8462, also 0.3% ahead. The AMD Radeon R9 M375X scores 8325, 1.3% behind. This cluster of scores indicates the 880M sits in a narrow performance band among older discrete laptop GPUs, roughly at parity with a GTX 675MX and within a couple percent of the MX330 and HD 8870M.

Looking at the 880M's individual tests, the Passmark results show a clear pattern. The DirectX 11 score of 73 is more than double the DirectX 12 score of 32 and the DirectX 10 score of 31. The DirectX 9 score of 97 is the highest among the API tests. This suggests the 880M is particularly efficient in legacy DirectX workloads, while its DirectX 12 and DirectX 10 performance is comparatively weaker. The Passmark GPU Compute score of 3719 is roughly half the G3D score, indicating that compute throughput is solid but not the GPU's primary strength. The Geekbench Vulkan score of 40006 is higher than the OpenCL score of 31285, which suggests the RDNA 3.5 architecture handles Vulkan workloads slightly better than OpenCL in this configuration.

For the N1X 48SM, the absence of benchmark data means its 28.83 TFLOPS FP32 figure and 900.9 GTexel/s texture rate are the only quantitative performance indicators available. These numbers, if realized in practice, would place it far above the 880M's measured results, but the database cannot verify this until tests are run.

Specification Differences

The two GPUs differ in nearly every measurable specification. The AMD Radeon 880M uses the Strix Point chip on RDNA 3.5 architecture with a 4 nm process, while the NVIDIA N1X 48SM uses the GB20B chip on Blackwell 2.0 architecture with a 5 nm process. The 880M integrates 34,000 million transistors on a 233 mm² die; the N1X 48SM's transistor count is unknown, but its die measures 382 mm². The 880M's base clock is 400 MHz with a boost of 2900 MHz; the N1X 48SM's base clock is 741 MHz with a boost of 2346 MHz. The 880M uses system shared memory, while the N1X 48SM has 128 GB of LPDDR5X on a 256-bit bus with 273.2 GB/s bandwidth.

Shader resources are heavily skewed toward the N1X 48SM: 6144 shading units versus 768, 384 TMUs versus 48, 48 ROPs versus 16, 48 RT cores versus 12, and 192 tensor cores versus none. Compute throughput follows the same pattern, with the N1X 48SM delivering 28.83 TFLOPS FP32 and FP16 versus the 880M's 4.454 TFLOPS in both. Texture and pixel rates are similarly lopsided, with the N1X 48SM at 900.9 GTexel/s and 112.6 GPixel/s against the 880M's 139.2 GTexel/s and 46.40 GPixel/s.

The Verdict

The recorded data supports only one conclusion: the AMD Radeon 880M is a measured, functioning integrated GPU with a defined performance tier, while the NVIDIA N1X 48SM is an unmeasured part with no benchmark results to substantiate its specifications. For users choosing based on available evidence, the 880M offers confirmed performance around the level of a GeForce GTX 675MX, with an average score of 8436 and a 43rd percentile standing. The N1X 48SM's 50th percentile placement is a default value, not a tested result, and its average score of zero confirms the absence of data.

The N1X 48SM's hardware specifications, however, describe a GPU in a different class. Its 28.83 TFLOPS FP32, 6144 shading units, 192 tensor cores, and 273.2 GB/s of dedicated memory bandwidth indicate a design aimed at workloads far beyond the 880M's scope. The 880M's 4.454 TFLOPS and system shared memory position it as a low-power integrated solution, reflected in its 15 W TDP. The N1X 48SM's TDP is unknown, but its die size of 382 mm² and memory subsystem suggest a much more demanding part.

The 880M is the safer choice when measured data matters. Its benchmark results show consistent performance across DirectX 9 through DirectX 12, with particular strength in legacy APIs, and its compute scores in Geekbench confirm functional OpenCL and Vulkan support. The N1X 48SM should only be selected when its theoretical specifications are sufficient justification, because no recorded performance data exists to validate its capabilities. The database will need benchmark entries for the N1X 48SM before any empirical comparison with the 880M can be made. Until then, the 880M remains the only one of the two with demonstrated performance.
