AMD Radeon 780M vs NVIDIA N1X 40SM Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Radeon 780M and the NVIDIA N1X 40SM. The head-to-head benchmark array is empty, and neither part records a win count. This makes a side-by-side comparison of specific test scores impossible. However, the available data allows for meaningful analysis through each part's own benchmark results, architectural characteristics, and relative positioning.

The AMD Radeon 780M has three recorded benchmark scores. In 3DMark Steel Nomad DX12, it scores 480. In Geekbench OpenCL, it reaches 18602. In Geekbench Vulkan, it achieves 33683. These results produce an average benchmark score of 17588. The NVIDIA N1X 40SM has zero recorded benchmark scores in the database, leaving its average benchmark score at 0.

The 780M's percentile ranking against all GPUs is 61. The N1X 40SM sits at percentile 50. This indicates that the 780M outperforms a larger fraction of the GPU population in the database, despite the N1X 40SM having a more advanced architecture and a much higher theoretical compute ceiling.

The nearest rivals for the 780M provide context for its average score. The AMD Radeon Pro 560 has an average score of 17551, which is 0.2% lower than the 780M. The AMD Radeon Pro 460 averages 17509, 0.5% lower. On the other side, the NVIDIA GeForce RTX 4060 averages 17639, 0.3% higher than the 780M, and the AMD Radeon HD 7790 averages 17666, 0.4% higher. These deltas are all under one percent, placing the 780M in a tightly contested performance band with those desktop parts.

Where Each One Wins

The AMD Radeon 780M wins in the only measurable benchmark categories available. It records concrete scores in three tests, while the NVIDIA N1X 40SM has no benchmark entries. The 780M's Geekbench Vulkan score of 33683 is notably higher than its OpenCL score of 18602, indicating strong performance under the Vulkan API. The 3DMark Steel Nomad DX12 score of 480 is a lower absolute number but reflects a different workload type.

For the N1X 40SM, the absence of benchmark data means it cannot claim any recorded wins. Its advantage exists only in theoretical specifications. It has 5120 shading units versus 768 for the 780M, 320 texture mapping units versus 48, and 40 render output units versus 32. It also includes 40 ray tracing cores and 160 tensor cores, while the 780M has 12 ray tracing cores and no tensor cores. These figures suggest a much larger compute pipeline, but without benchmark scores, the database cannot confirm real-world performance.

The 780M also wins in power efficiency based on recorded data. Its TDP is 15 W. The N1X 40SM has an unknown TDP, so no comparison can be made. The 780M's process node is 4 nm versus 5 nm for the N1X 40SM, which gives the AMD part a manufacturing advantage in density. The 780M packs 25,390 million transistors onto a 178 mm² die, yielding a transistor density of 142.6 million per square millimeter. The N1X 40SM has an unknown transistor count on a 382 mm² die.

The Verdict

Based strictly on recorded data, the AMD Radeon 780M is the only part with measurable benchmark performance. Its average benchmark score of 17588 places it above half the GPU population, with a percentile ranking of 61. The NVIDIA N1X 40SM has no benchmark scores, so the database cannot validate its performance claims. Users requiring verified performance data should consider the 780M, as it demonstrates consistent results across three different test workloads.

The N1X 40SM does offer a substantially larger hardware configuration on paper. Its 5120 shading units represent a 6.7x increase over the 780M's 768. Its FP32 throughput of 24.02 TFLOPS is 2.7x the 780M's 8.909 TFLOPS. Its texture rate of 750.7 GTexel/s is 5.4x higher than the 780M's 139.2 GTexel/s. Its pixel rate of 93.84 GPixel/s is slightly above the 780M's 92.80 GPixel/s. These are large gaps, but they do not translate into benchmark wins without recorded test data.

For the 780M, the practical choice is clear for anyone needing immediate, verified performance numbers. For the N1X 40SM, the choice depends on whether the hardware specifications match the intended workload, since no benchmark evidence exists to confirm how those specifications perform in practice.
