AMD Radeon 880M vs NVIDIA N1X 40SM Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison: the AMD Radeon 880M has a full set of benchmark results, while the NVIDIA N1X 40SM has no recorded benchmark scores in the database. This means direct head-to-head numerical comparisons are impossible from the available measurements. The 880M's average benchmark score is 8,436, placing it at the 43rd percentile among all GPUs. Its nearest rivals include the NVIDIA GeForce GTX 675MX with an average score of 8,427 (a 0.1% difference), the NVIDIA GeForce MX330 at 8,458 (-0.3%), and the AMD Radeon HD 8870M at 8,462 (-0.3%). The AMD Radeon R9 M375X trails slightly at 8,325, which is 1.3% behind the 880M.

The 880M shows its strongest results in Geekbench Vulkan with a score of 40,006, followed by Geekbench OpenCL at 31,285. Passmark G3D delivers 7,615, while Passmark G2D reaches 969. Compute workloads produce a Passmark GPU Compute score of 3,719. Legacy DirectX tests show lower numbers: Passmark DirectX 9 scores 97, DirectX 11 scores 73, DirectX 10 scores 31, and DirectX 12 scores 32. The 3DMark Steel Nomad DX12 result is 535.

The NVIDIA N1X 40SM, by contrast, carries no benchmark entries, no average score, and no nearest rival data. Its percentile ranking of 50 appears in the database, but without actual measurements, this cannot be compared meaningfully to the 880M's 43rd percentile. The database records zero wins for either part in head-to-head testing because no head-to-head benchmark data exists.

What can be stated from the recorded data is that the 880M has a measurable performance profile across multiple APIs and workloads. The N1X 40SM has a theoretical specification sheet but no empirical results. Therefore, any numerical comparison between the two must rely on architectural specifications rather than benchmark outcomes.

Where Each One Wins

Without shared benchmark results, the division of strengths must be inferred from the specification differences recorded in the database.

The AMD Radeon 880M demonstrates its capabilities across a broad range of established graphics APIs. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and its benchmark results span DirectX 9 through DirectX 12, OpenCL, Vulkan, and compute workloads. This breadth suggests a design intended for compatibility with legacy and modern titles alike. The 880M's 4.454 TFLOPS FP32 throughput and 139.2 GTexel/s texture rate, combined with 768 shading units, 48 texture mapping units, and 16 raster output units, form a compact integrated graphics processor.

The NVIDIA N1X 40SM, on the other hand, presents a much larger theoretical configuration. Its 5,120 shading units, 320 TMUs, 40 ROPs, 40 RT cores, and 160 tensor cores indicate a design aimed at compute-heavy and ray-traced workloads. The FP32 throughput of 24.02 TFLOPS is more than five times the 880M's figure, and the texture rate of 750.7 GTexel/s is similarly dominant. The N1X also records 128 GB of LPDDR5X memory on a 256-bit bus with 273.2 GB/s bandwidth, whereas the 880M uses system-shared memory with bandwidth described as system dependent.

The 880M wins in the domain of software compatibility. Its API support includes industry-standard DirectX and Vulkan versions, while the N1X 40SM lists DirectX, OpenGL, and Vulkan all as N/A. The 880M also has a known process node of 4 nm and a transistor count of 34,000 million, while the N1X's transistor count is listed as unknown.

The N1X 40SM wins in raw specification density. Its pixel rate of 93.84 GPixel/s doubles the 880M's 46.40 GPixel/s. Its boost clock of 2346 MHz sits below the 880M's 2900 MHz boost, but the massive difference in shading units, TMUs, and ROPs more than compensates. The N1X also uses PCIe 5.0 x16, while the 880M uses PCIe 4.0 x8.

The Verdict

From the recorded data, the choice between these two parts depends entirely on whether benchmark results or specifications take priority. The AMD Radeon 880M has verified performance numbers across multiple tests and APIs. Its average benchmark score of 8,436 places it in a competitive position against older discrete GPUs like the GeForce GTX 675MX and the Radeon HD 8870M. For users who require working DirectX or Vulkan support today, the 880M is the only part with demonstrated compatibility.

The NVIDIA N1X 40SM offers a specification sheet that suggests far higher theoretical performance. The 24.02 TFLOPS FP32 figure, 160 tensor cores, and 273.2 GB/s memory bandwidth indicate a part designed for substantial compute and AI workloads. However, the database contains zero benchmark results for this GPU, and its API support is listed as N/A. This makes it impossible to confirm real-world performance from the available data.

The 880M's 15 W TDP and IGP form factor suggest an efficient integrated solution, while the N1X's TDP is unknown. Both use no power connectors. The 880M has been in production since July 2024, while the N1X's release date is recorded as May 2026. The 880M's predecessor is listed as Navi II IGP, while the N1X has no recorded predecessor.

A user needing a verified, working integrated GPU with broad API support should select the AMD Radeon 880M. A user prioritizing raw specifications and willing to accept the absence of benchmark data might consider the NVIDIA N1X 40SM, but the lack of recorded performance and API support makes this a speculative choice.
