NVIDIA N1X 40SM vs NVIDIA RTX 2000 Ada Generation Comparison

The NVIDIA N1X 40SM and the NVIDIA RTX 2000 Ada Generation are both 5 nm TSMC designs, but they occupy different positions in the database. The N1X 40SM is a Blackwell 2.0 IGP built around the GB20B chip, with a 382 mm² die and 5120 shading units. The RTX 2000 Ada Generation is an Ada Lovelace workstation card using the AD107 chip, with 2816 shading units, a 70 W TDP, and a launch MSRP of 649 USD. The database contains benchmark scores for the RTX 2000 Ada Generation only; the N1X 40SM has no recorded benchmark entries and an average score of 0.

Where Each One Wins

Within the recorded benchmark suite, the RTX 2000 Ada Generation holds every win. Its 3DMark Steel Nomad DX12 result is 1767, Geekbench OpenCL is 78074, Geekbench Vulkan is 83360, Passmark G3D is 16927, and Passmark GPU Compute is 7834. The Passmark DirectX results are 216 in DX9, 138 in DX11, 82 in DX10, and 71 in DX12, with a G2D score of 1072. This places the card at the 63rd percentile of all GPUs with an average benchmark score of 18954. Its nearest recorded rivals are the NVIDIA Quadro K6000 (19030, delta -0.4%), AMD Radeon RX 6600 (19036, delta -0.4%), NVIDIA Tesla K80 (18866, delta 0.5%), and NVIDIA GeForce RTX 4050 Mobile (19049, delta -0.5%).

The N1X 40SM has no benchmark wins in the database because no benchmarks were recorded. It sits at the 50th percentile with an average score of 0. Its specification sheet points to wins in compute-heavy and memory-capacity scenarios: 5120 shading units, 320 TMUs, 40 RT cores, 160 tensor cores, 24.02 TFLOPS FP32, and 24.02 TFLOPS FP16. It also carries 128 GB of LPDDR5X memory on a 256-bit bus with 273.2 GB/s bandwidth. The RTX 2000 Ada Generation cannot match those resources, but it is the only part with DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 support.

Architecture Differences

The two GPUs share a 5 nm TSMC process but use different architectures. The N1X 40SM is Blackwell 2.0 from the Blackwell IGP (N1x) generation, built on the GB20B chip with a 382 mm² die. The RTX 2000 Ada Generation is Ada Lovelace from the Workstation Ada (x000A) generation, built on the AD107 chip with a 159 mm² die and 18,900 million transistors, giving a transistor density of 118.9M / mm². The N1X transistor count is listed as unknown.

Core counts differ sharply. The N1X 40SM has 5120 shading units, 320 TMUs, 40 ROPs, 40 RT cores, and 160 tensor cores. The RTX 2000 Ada Generation has 2816 shading units, 88 TMUs, 48 ROPs, 22 RT cores, and 88 tensor cores. The N1X leads in every core count except ROPs, where the RTX 2000 Ada has 48 versus 40.

Clock behavior also differs. Base clocks are 741 MHz for the N1X and 1620 MHz for the RTX 2000 Ada. Boost clocks are 2346 MHz and 2130 MHz respectively. Memory subsystems diverge as well: the N1X uses 128 GB LPDDR5X at 1067 MHz (8.5 Gbps effective) on a 256-bit bus for 273.2 GB/s, while the RTX 2000 Ada uses 16 GB GDDR6 at 2000 MHz (16 Gbps effective) on a 128-bit bus for 256.0 GB/s.

Rasterization rates separate the two. The N1X produces 93.84 GPixel/s and 750.7 GTexel/s, while the RTX 2000 Ada produces 102.2 GPixel/s and 187.4 GTexel/s. FP32 and FP16 throughput are 24.02 TFLOPS for the N1X and 12.00 TFLOPS for the RTX 2000 Ada, both with 1:1 FP16 ratios.

Form factor and interfaces are major differences. The N1X is an IGP with no power connectors, a PCIe 5.0 x16 interface, and one HDMI output. The RTX 2000 Ada is a dual-slot card with no power connectors, a PCIe 4.0 x8 interface, four mini-DisplayPort 1.4a outputs, a 70 W TDP, and a suggested PSU of 250 W. Its dimensions are 168 mm (6.6 inches) in length and 69 mm (2.7 inches) in height. The N1X lists no dimensions.

API support is the largest feature gap. The N1X lists DirectX, OpenGL, and Vulkan as N/A. The RTX 2000 Ada supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both parts are marked Active in production. The database release dates are 2026-05-31 for the N1X and 2024-02-11 for the RTX 2000 Ada. The RTX 2000 Ada lists Workstation Ampere as predecessor and Blackwell PRO W as successor; the N1X has no predecessor or successor entries.

The Verdict

The recorded data resolves the comparison in two directions. For software that depends on graphics APIs, the RTX 2000 Ada Generation is the only functional option: it has DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, plus four display outputs and a 70 W TDP. The N1X 40SM has no API support and only one HDMI output, so it cannot serve those workloads based on the database.

For compute throughput and memory capacity, the N1X 40SM dominates the specification comparison. It offers 24.02 TFLOPS FP32, 24.02 TFLOPS FP16, 128 GB LPDDR5X, and 273.2 GB/s of bandwidth. The RTX 2000 Ada Generation offers 12.00 TFLOPS FP32, 12.00 TFLOPS FP16, 16 GB GDDR6, and 256.0 GB/s. The N1X also has more shading units, TMUs, RT cores, and tensor cores.

The workload evidence points to the RTX 2000 Ada Generation for API-dependent tasks and to the N1X 40SM for raw compute and large memory capacity. The RTX 2000 Ada is the part with benchmark results, API coverage, and a compact dual-slot form factor. The N1X 40SM is the part with higher raw compute and a much larger memory pool, but no benchmark record or API support in the database.
