AMD Radeon 680M vs NVIDIA N1 16SM Comparison

The Verdict

The AMD Radeon 680M and NVIDIA N1 16SM occupy different positions in the integrated graphics landscape, and the available data shows they are not direct substitutes. The Radeon 680M is a proven, active part with recorded benchmark scores and established rivals, while the N1 16SM is a newer Blackwell IGP with no recorded benchmarks in the database.

For users selecting an integrated GPU today, the Radeon 680M is the only one with verified performance data. Its average benchmark score of 15270 places it in the 57th percentile of all GPUs, and it trades blows with discrete graphics cards from the previous generation. The N1 16SM, by contrast, has an average benchmark score of 0 with no entries in the database, meaning its real-world performance cannot be compared directly. The N1 16SM does carry a significantly larger die (382 mm² versus 208 mm²), more shading units (2048 versus 768), and a higher boost clock (2346 MHz versus 2200 MHz), which suggests higher theoretical compute, but the absence of measured results means those specifications cannot be translated into verified performance claims.

The database verdict is straightforward: the Radeon 680M is the choice for anyone needing verified integrated graphics performance today. The N1 16SM is a future part (release date of 2026-05-31) whose capabilities remain unmeasured in this database.

Architecture Differences

The two integrated GPUs come from different architectural generations and process nodes. The Radeon 680M uses the Rembrandt+ chip based on RDNA 2.0 architecture, manufactured on a 6 nm TSMC process. It belongs to the Navi II IGP generation (Rembrandt Mobile). The N1 16SM uses the GB20B chip based on Blackwell 2.0 architecture, manufactured on a 5 nm TSMC process, and belongs to the Blackwell IGP (N1x) generation.

The transistor counts differ significantly: the Radeon 680M packs 13,100 million transistors into a 208 mm² die, yielding a transistor density of 63.0M per mm². The N1 16SM has an unknown transistor count but a larger 382 mm² die, so its density cannot be calculated from the available data.

The Radeon 680M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 16SM lists all APIs as N/A in the database, meaning no API support levels are recorded. The Radeon 680M uses system-shared memory, while the N1 16SM has dedicated 128 GB of LPDDR5X memory on a 256-bit bus with 273.2 GB/s bandwidth. The Radeon 680M's memory bandwidth is system dependent.

Both are IGP slot-width parts with no power connectors. The Radeon 680M has a recorded TDP of 50 W, while the N1 16SM's TDP is unknown. The bus interfaces differ: the Radeon 680M uses PCIe 4.0 x8, while the N1 16SM uses PCIe 5.0 x16. The Radeon 680M's display outputs are portable-device dependent, while the N1 16SM lists 1x HDMI.

The N1 16SM has dedicated hardware features that the Radeon 680M lacks or has in different quantities. The Radeon 680M has 768 shading units, 48 texture mapping units, 32 ROPs, and 12 ray tracing cores. The N1 16SM has 2048 shading units, 128 TMUs, 24 ROPs, 16 ray tracing cores, and 64 tensor cores. The Radeon 680M has no tensor cores recorded.

Memory configurations are entirely different: the Radeon 680M uses system-shared memory, while the N1 16SM has 128 GB of LPDDR5X on a 256-bit bus with 273.2 GB/s bandwidth.

Compute resources diverge sharply. The Radeon 680M has 768 shading units, 48 TMUs, 32 ROPs, and 12 ray tracing cores. The N1 16SM has 2048 shading units, 128 TMUs, 24 ROPs, 16 ray tracing cores, and 64 tensor cores. Pixel rates are 70.40 GPixel/s for the Radeon 680M versus 56.30 GPixel/s for the N1 16SM.

FP32 compute is 3.379 TFLOPS for the Radeon 680M versus 9.609 TFLOPS for the N1 16SM. FP16 is 6.758 TFLOPS (2:1) for the Radeon 680M versus 9.609 TFLOPS (1:1) for the N1 16SM. The Radeon 680M has a TDP of 50 W; the N1 16SM's TDP is unknown. The bus interface is PCIe 4.0 x8 for the Radeon 680M versus PCIe 5.0 x16 for the N1 16SM.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the Radeon 680M and the N1 16SM, and the N1 16SM has no individual benchmark scores recorded. The Radeon 680M, however, has three recorded benchmarks: a 3DMark Steel Nomad DX12 score of 378, a Geekbench OpenCL score of 23468, and a Geekbench Vulkan score of 21965.

Because the N1 16SM has no benchmark data, direct numerical comparison is impossible. What can be compared is the Radeon 680M's standing against its nearest rivals, which provides context for its performance class. The Radeon 680M scores 15270 on average, which is within 0.1% of the GeForce GTX 580 (15283) and the GeForce RTX 2060 (15290). It is 0.5% ahead of the GeForce RTX 3050 OEM (15199) and 0.7% ahead of the AMD Radeon RX 7600 (15171). These deltas are all within a single percentage point, indicating the Radeon 680M sits in a tightly clustered performance band with those discrete GPUs.

The theoretical specifications of the N1 16SM suggest higher raw compute: its FP32 rating of 9.609 TFLOPS is 2.8 times the Radeon 680M's 3.379 TFLOPS, and its texture rate of 300.3 GTexel/s is 2.8 times the Radeon 680M's 105.6 GTexel/s. However, the N1 16SM's lower pixel rate (56.30 GPixel/s versus 70.40 GPixel/s) means it renders fewer pixels per second despite higher shader throughput. The N1 16SM's base clock of 741 MHz is far lower than the Radeon 680M's 2000 MHz, though its boost clock of 2346 MHz is higher. These numbers cannot be validated against actual benchmark results, so they remain theoretical.

The Radeon 680M's recorded results place it in the 57th percentile of all GPUs, which is a measured position. The N1 16SM's 50th percentile is assigned despite the zero average score, so it does not reflect measured performance.

Where Each One Wins

Based strictly on recorded data, the Radeon 680M wins in every measurable category because it is the only part with benchmark results. It has verified scores across three tests (3DMark Steel Nomad DX12, Geekbench OpenCL, Geekbench Vulkan) and a defined average of 15270. Its pixel rate of 70.40 GPixel/s exceeds the N1 16SM's 56.30 GPixel/s, meaning it fills pixels faster. It has a higher base clock (2000 MHz versus 741 MHz) and a lower TDP (50 W versus unknown), which matters for integrated designs where power is constrained. It also has full API support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the N1 16SM's API support is unrecorded.

The N1 16SM wins on paper in raw compute resources. It has 2048 shading units versus 768, 128 TMUs versus 48, and 64 tensor cores versus none. Its FP32 throughput of 9.609 TFLOPS is nearly three times the Radeon 680M's 3.379 TFLOPS. It has dedicated 128 GB of LPDDR5X memory with 273.2 GB/s bandwidth, whereas the Radeon 680M relies on system-shared memory with system-dependent bandwidth. Its texture rate of 300.3 GTexel/s is 2.8 times higher, and it uses a wider PCIe 5.0 x16 interface versus PCIe 4.0 x8.

The use-case split follows from this data. The Radeon 680M is suitable for applications that need verified integrated graphics performance now, particularly where pixel-fill operations and established driver/API support matter. Its performance parity with discrete GPUs like the GeForce RTX 2060 and RX 7600, within 0.1% and 0.7% respectively, makes it a credible option for mainstream gaming and general GPU compute at integrated power levels.

The N1 16SM is positioned for workloads that can exploit its massive shader count, tensor cores, and dedicated memory bandwidth, such as compute-heavy tasks that scale with FP32 throughput or tensor operations. Its 64 tensor cores and 9.609 TFLOPS FP16 (1:1) suggest machine-learning acceleration capabilities, but with no benchmark results and no API support recorded, the database cannot confirm these advantages in practice. Its lower pixel rate and much lower base clock indicate it may not be optimized for rasterization-heavy workloads despite the higher boost clock.

The Radeon 680M remains the only part with a production status of Active and a release date of 2023-01-02, while the N1 16SM is dated 2026-05-31, so the Radeon 680M is available in the present while the N1 16SM is a future release. For any current deployment, the Radeon 680M is the only choice with measured evidence. For future systems where the N1 16SM's theoretical compute advantages can be validated, it could serve a different role, but that conclusion awaits benchmark data.
