NVIDIA N1 16SM vs NVIDIA RTX 4000 Ada Generation Comparison

The Verdict

The recorded data presents an unusual comparison: one product has no benchmark scores at all, while the other is a proven workstation performer. The NVIDIA N1 16SM, a Blackwell 2.0 integrated graphics processor, sits at the 50th percentile among all GPUs with an average benchmark score of zero. The NVIDIA RTX 4000 Ada Generation, in contrast, holds the 95th percentile with an average benchmark score of 135,218 across two recorded tests. The verdict is straightforward from this data: the RTX 4000 Ada Generation is the only part here with measurable compute performance, and it is a decisive winner in every benchmark category that the database records.

The N1 16SM has no recorded benchmarks, no nearest rivals, and zero wins in head-to-head testing. Its 50th percentile placement with a zero score indicates that it has not been subjected to the same validation process. The RTX 4000 Ada Generation, however, delivers a Geekbench OpenCL score of 146,593 and a Geekbench Vulkan score of 123,842. These numbers place it far above the N1 16SM in any direct comparison, even though the head-to-head benchmark table remains empty. Users seeking a graphics card for workstation tasks should look at the RTX 4000 Ada Generation based on the evidence. Users considering the N1 16SM should understand that the database contains no performance validation for it whatsoever.

Architecture Differences

The two processors come from different architectural lineages. The N1 16SM uses the GB20B chip with Blackwell 2.0 architecture, classified as a Blackwell IGP (N1x) generation part. The RTX 4000 Ada Generation uses the AD104 chip with Ada Lovelace architecture, belonging to the Workstation Ada generation. Both are manufactured on a 5 nm process at TSMC, but the similarity ends there.

The N1 16SM has a die size of 382 mm² with transistor count listed as unknown. The RTX 4000 Ada Generation has a die size of 294 mm² and contains 35,800 million transistors, yielding a transistor density of 121.8 million per mm². The N1 16SM does not report a transistor density. This means the N1 16SM physically occupies more silicon area despite lacking published transistor figures, which suggests a different design philosophy for an integrated GPU.

Clock behavior also differs substantially. The N1 16SM has a base clock of 741 MHz and a boost clock of 2,346 MHz. The RTX 4000 Ada Generation runs at a 1,500 MHz base clock and a 2,175 MHz boost clock. The N1 16SM starts much lower but boosts higher, while the RTX 4000 Ada Generation maintains a higher floor. Memory clocks differ as well: the N1 16SM uses 1,067 MHz with 8.5 Gbps effective speed, while the RTX 4000 Ada Generation uses 2,250 MHz with 18 Gbps effective speed.

The memory subsystem takes opposite approaches. The N1 16SM features 128 GB of LPDDR5X on a 256-bit bus, delivering 273.2 GB/s of bandwidth. The RTX 4000 Ada Generation has 20 GB of GDDR6 on a 160-bit bus, providing 360.0 GB/s of bandwidth. The N1 16SM offers far more capacity, while the RTX 4000 Ada Generation offers higher bandwidth despite a narrower bus.

Shader resources heavily favor the RTX 4000 Ada Generation. It has 6,144 shading units, 192 texture mapping units, 64 render output units, 48 ray tracing cores, and 192 tensor cores. The N1 16SM has 2,048 shading units, 128 TMUs, 24 ROPs, 16 RT cores, and 64 tensor cores. The RTX 4000 Ada Generation has exactly three times the shading units, three times the RT cores, and three times the tensor cores.

API support diverges completely. The N1 16SM lists DirectX, OpenGL, and Vulkan as N/A. The RTX 4000 Ada Generation supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This is a critical distinction: the N1 16SM cannot run standard graphics APIs according to the database, which may explain its absence of benchmark results.

FAQ

Q: Why does the N1 16SM have no benchmark scores?

A: The database lists the N1 16SM with zero benchmarks, an average benchmark score of 0, and no nearest rivals. Its percentile rank of 50 appears to be a default placement rather than a measured result. The RTX 4000 Ada Generation, by contrast, has two recorded benchmark scores and a 95th percentile rank.

Q: Which GPU has more memory capacity?

A: The N1 16SM has 128 GB of LPDDR5X, which is 6.4 times the 20 GB of GDDR6 found on the RTX 4000 Ada Generation. This capacity difference likely targets very different use cases, with the N1 16SM potentially aimed at memory-heavy workloads that do not require standard graphics APIs.

Q: How much faster is the RTX 4000 Ada Generation in raw compute?

A: The RTX 4000 Ada Generation delivers 26.73 TFLOPS of FP32 and FP16 compute. The N1 16SM delivers 9.609 TFLOPS of FP32 and FP16. This makes the RTX 4000 Ada Generation approximately 2.8 times faster in raw floating-point throughput.

Q: Can the N1 16SM run modern graphics workloads?

A: The database lists DirectX, OpenGL, and Vulkan support as N/A for the N1 16SM. The RTX 4000 Ada Generation supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. These API limitations likely prevent the N1 16SM from being tested with standard graphics benchmarks.

Head-to-Head Benchmarks

The head-to-head benchmark table contains no entries, and neither product records any wins in direct comparison. However, the RTX 4000 Ada Generation has two individual benchmark scores that can be evaluated against the N1 16SM's complete lack of scores. In Geekbench OpenCL, the RTX 4000 Ada Generation scores 146,593. In Geekbench Vulkan, it scores 123,842. The N1 16SM has no corresponding scores in either test.

The RTX 4000 Ada Generation's average benchmark score of 135,218 places it at the 95th percentile of all GPUs. Its nearest rivals in the database include the NVIDIA A10M at 135,230 with a 0% delta, the AMD Radeon PRO W6800 at 135,396 with a -0.1% delta, the AMD Radeon Pro W6800X Duo at 135,774 with a -0.4% delta, and the AMD Radeon PRO V620 at 136,472 with a -0.9% delta. These deltas indicate that the RTX 4000 Ada Generation performs nearly identically to the A10M, while slightly trailing the three AMD workstation cards.

The N1 16SM sits at the 50th percentile with an average score of zero, which places it below all recorded GPUs in the database. Since it has no nearest rivals, no delta values can be calculated. The absence of data means the N1 16SM cannot be positioned relative to any other product in the database.

The biggest measurable wins belong entirely to the RTX 4000 Ada Generation. Its OpenCL score of 146,593 exceeds its own Vulkan score of 123,842 by 18.4%, showing that OpenCL workloads extract more performance from the hardware. The difference between the two API scores suggests the RTX 4000 Ada Generation has stronger OpenCL optimization or that Vulkan workloads hit different bottlenecks.

Where Each One Wins

Based strictly on recorded data, the RTX 4000 Ada Generation wins every measurable category. It leads in raw compute with 26.73 TFLOPS versus 9.609 TFLOPS. It leads in memory bandwidth with 360.0 GB/s versus 273.2 GB/s. It leads in pixel throughput with 139.2 GPixel/s versus 56.30 GPixel/s. It leads in texture throughput with 417.6 GTexel/s versus 300.3 GTexel/s. It leads in shading units, TMUs, ROPs, RT cores, and tensor cores by factors of 2 to 3.

The RTX 4000 Ada Generation also wins in software compatibility. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the N1 16SM lists all three APIs as N/A. This means the RTX 4000 Ada Generation can run the full range of graphics workloads and benchmarks, which is reflected in its two recorded scores and 95th percentile placement.

The N1 16SM has one specification advantage: memory capacity. Its 128 GB of LPDDR5X dwarfs the RTX 4000 Ada Generation's 20 GB of GDDR6. This sixfold capacity difference could serve workloads that require massive in-memory datasets, such as large language model inference or data processing tasks that do not rely on standard graphics APIs. The N1 16SM also uses a newer PCIe 5.0 x16 interface compared to PCIe 4.0 x16, which offers higher theoretical transfer rates to the host system.

The N1 16SM also has a higher boost clock of 2,346 MHz versus 2,175 MHz, though its base clock of 741 MHz is far lower than the 1,500 MHz base clock of the RTX 4000 Ada Generation. The N1 16SM's larger die size of 382 mm² versus 294 mm² suggests a more complex physical layout, though without transistor counts, the density implications remain unclear.

For workstation graphics, rendering, or any API-based workload, the RTX 4000 Ada Generation is the only viable option according to the data. For scenarios requiring maximum memory capacity without standard API support, the N1 16SM presents a different tradeoff, though its performance in such scenarios is unmeasured. The database cannot confirm any performance advantage for the N1 16SM because no benchmark results exist for it.
