Architecture Differences

The AMD Radeon 760M and NVIDIA N1X 48SM represent fundamentally different architectural approaches despite both being integrated graphics processors. The AMD part uses the RDNA 3.0 architecture on the Phoenix chip, part of the Navi III IGP generation. It is built on a 4 nm TSMC process with 25,390 million transistors packed into a 178 mm² die, yielding a transistor density of 142.6 million transistors per square millimeter.

The NVIDIA N1X 48SM uses the Blackwell 2.0 architecture on the GB20B chip, part of the Blackwell IGP generation. It is built on a 5 nm TSMC process with an unknown transistor count but a significantly larger die size of 382 mm². This larger die area suggests a more complex design despite the older process node.

The compute resources differ dramatically between the two. The AMD Radeon 760M has 512 shading units, 32 texture mapping units, and 16 render output units. It includes 8 ray tracing cores but no tensor cores. The NVIDIA N1X 48SM has 6144 shading units, 384 texture mapping units, and 48 render output units. It includes 48 ray tracing cores and 192 tensor cores, giving it a substantial advantage in both conventional shading work and specialized compute tasks.

Memory architecture presents another major distinction. The AMD Radeon 760M relies on system shared memory, making its performance heavily dependent on the host system's memory configuration. The NVIDIA N1X 48SM has dedicated 128 GB of LPDDR5X memory on a 256-bit bus with 273.2 GB/s of bandwidth, a substantial allocation for an integrated part.

The interface also differs: the AMD part uses PCIe 4.0 x8, while the NVIDIA part uses PCIe 5.0 x16. The NVIDIA GPU has a single HDMI display output, while the AMD GPU's display outputs are motherboard dependent. API support shows a notable split: the AMD Radeon 760M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the NVIDIA N1X 48SM lists N/A for DirectX, OpenGL, and Vulkan support in the database.

Where Each One Wins

The AMD Radeon 760M wins decisively in the availability of measured performance data. The database contains ten benchmark scores for this GPU across 3DMark, Geekbench, and PassMark testing suites. This allows for concrete performance comparisons and trend analysis.

The NVIDIA N1X 48SM wins decisively in raw architectural capability based on its specifications. With 6144 shading units compared to 512, the NVIDIA part has 12 times the shading resources. Its 384 texture mapping units and 48 render output units dwarf the AMD's 32 and 16 respectively. The NVIDIA part also has 48 ray tracing cores and 192 tensor cores, while the AMD part has only 8 ray tracing cores and no tensor cores.

The NVIDIA N1X 48SM also wins on memory capacity and bandwidth. With 128 GB of dedicated LPDDR5X memory providing 273.2 GB/s of bandwidth, it does not depend on system memory allocation. The AMD Radeon 760M's performance is system dependent, meaning its effective memory performance varies with the host platform.

In theoretical throughput, the NVIDIA part shows substantial advantages. Its pixel rate of 112.6 GPixel/s compares to 41.58 GPixel/s for the AMD part. Its texture rate of 900.9 GTexel/s compares to 83.17 GTexel/s. Its FP32 compute of 28.83 TFLOPS compares to 5.323 TFLOPS. Both parts achieve a 1:1 ratio for FP16 to FP32 performance.

The AMD Radeon 760M wins on clock speed, with a 2599 MHz boost clock versus 2346 MHz for the NVIDIA part. It also has a lower power envelope at 15 W TDP, while the NVIDIA part's TDP is unknown. The AMD part has a smaller die size and uses an older, but more refined, release date.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the AMD Radeon 760M and the NVIDIA N1X 48SM. The head-to-head benchmark array is empty, and both the win counters for the AMD part and the NVIDIA part stand at zero.

This absence of comparative data creates a unique analytical situation. The AMD Radeon 760M has a full suite of individual benchmark scores, while the NVIDIA N1X 48SM has no recorded benchmarks at all. The AMD part's average benchmark score is 6019, placing it in the 35th percentile of all GPUs in the database. The NVIDIA part has an average benchmark score of 0 and sits in the 50th percentile, though this percentile figure appears based on specifications rather than measured performance.

The AMD Radeon 760M's nearest rivals provide context for its measured performance. The AMD Radeon RX 6400 scores 6001, which is 0.3% higher than the 760M. The NVIDIA GeForce GTX 770M scores 6000, also 0.3% higher. The NVIDIA RTX PRO 6000 Blackwell Server scores 5996, which is 0.4% higher. The NVIDIA Quadro P2000 scores 6049, which is 0.5% lower than the 760M. These tight margins show the 760M sits in a competitive performance band among these discrete and older integrated parts.

For the NVIDIA N1X 48SM, the lack of benchmark scores means its performance must be inferred from its architectural specifications. The theoretical throughput figures indicate a GPU with substantially higher compute capacity than the AMD Radeon 760M, but without measured results, real-world performance cannot be confirmed from the database.

The individual benchmark scores for the AMD Radeon 760M show its performance profile. In 3DMark Steel Nomad DX12, it scores 400. In Geekbench, it achieves 20255 in OpenCL and 30336 in Vulkan. PassMark tests show scores of 19 for DirectX 10, 52 for DirectX 11, 25 for DirectX 12, and 65 for DirectX 9. The PassMark G2D score is 890, the G3D score is 5310, and the GPU compute score is 2840.

The Verdict

The data presents a clear but incomplete picture. The AMD Radeon 760M is a measured, characterized product with ten benchmark scores and a defined competitive position. Its average benchmark score of 6019 places it in the 35th percentile of all GPUs, with nearest rivals within a 0.5% performance band. It offers proven DirectX 12 Ultimate support, OpenGL 4.6, and Vulkan 1.4, making it a functional choice for systems requiring integrated graphics with broad API compatibility.

The NVIDIA N1X 48SM is a specification-heavy product with no measured performance data. Its architectural specifications suggest a much higher performance ceiling: 12 times the shading units, 12 times the texture mapping units, 3 times the render output units, 6 times the ray tracing cores, and 192 tensor cores where the AMD part has none. Its 128 GB of dedicated LPDDR5X memory with 273.2 GB/s bandwidth represents a fundamentally different memory approach than the AMD part's system shared memory.

The theoretical performance gap is substantial. The NVIDIA part's 28.83 TFLOPS FP32 performance is 5.4 times the AMD part's 5.323 TFLOPS. Its texture rate of 900.9 GTexel/s is 10.8 times higher. Its pixel rate of 112.6 GPixel/s is 2.7 times higher. These figures indicate the NVIDIA N1X 48SM is designed for a much heavier compute workload.

The AMD Radeon 760M is the only one of the two with confirmed, tested performance. Its 15 W TDP and 4 nm process make it an efficient integrated solution. Its smaller 178 mm² die and earlier release date indicate a mature product.

The NVIDIA N1X 48SM, with its larger 382 mm² die, 5 nm process, and later release date, represents a more ambitious design. Its unknown TDP and absence of API support details in the database create uncertainty about its software ecosystem. The PCIe 5.0 x16 interface suggests it targets systems with newer platform capabilities.

For users requiring verified integrated graphics performance today, the AMD Radeon 760M is the only option with measured data. For users evaluating future platform capabilities based on architectural specifications, the NVIDIA N1X 48SM shows significantly higher theoretical headroom. The database records no direct comparison, so any performance relationship between the two remains unverified.
