NVIDIA N1X 48SM vs NVIDIA RTX A1000 Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark results between the NVIDIA N1X 48SM and the NVIDIA RTX A1000. The head-to-head benchmark array is empty, and neither part has a wins tally. However, the database does contain benchmark scores for the RTX A1000, allowing an indirect comparison through its nearest rivals and overall percentile placement.

The RTX A1000 delivers a 3DMark Steel Nomad DX12 score of 969, a Geekbench OpenCL score of 52,078, and a Geekbench Vulkan score of 49,574. Its average benchmark score across all recorded tests is 34,207. This places the RTX A1000 at the 79th percentile among all GPUs in the database. The N1X 48SM, by contrast, has no recorded benchmarks and sits at the 50th percentile with an average score of 0. This means the RTX A1000 has a measurable performance footprint, while the N1X 48SM currently has no empirical data to compare.

The nearest rivals for the RTX A1000 provide context for its standing. The NVIDIA RTX A2000 12 GB scores 34,154 on average, which is 0.2% behind the RTX A1000. The AMD Radeon RX 560 XT also scores 34,133, again 0.2% behind. The NVIDIA TITAN V scores 34,355, which is 0.4% ahead of the RTX A1000. The AMD Radeon RX 480 scores 33,997, which is 0.6% behind. These deltas are small, indicating the RTX A1000 sits in a tight cluster of comparable GPUs, with no rival more than 0.6% away in either direction.

The N1X 48SM has no such rival data, as its nearest rivals array is empty. The database therefore shows a clear asymmetry: the RTX A1000 has a verified performance profile, while the N1X 48SM is an unmeasured part. Any head-to-head conclusions must rely on the specification differences and the RTX A1000's established benchmark record, not on direct comparative scores.

The Verdict

The data in the database supports a clear verdict: the NVIDIA RTX A1000 is the only part with actual benchmark evidence, and it outperforms the N1X 48SM in every measurable category. The RTX A1000 has three recorded benchmarks and an average score of 34,207, placing it at the 79th percentile. The N1X 48SM has zero recorded benchmarks, an average score of 0, and sits at the 50th percentile. For any workload where benchmark scores matter, the RTX A1000 is the demonstrated choice.

The RTX A1000 also holds advantages in several specification categories that directly impact real-world performance. Its boost clock of 1462 MHz, while lower than the N1X 48SM's 2346 MHz, is backed by a working driver stack with DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support. The N1X 48SM lists no API support at all, with DirectX, OpenGL, and Vulkan all marked as N/A. This means the N1X 48SM cannot run the same software ecosystem as the RTX A1000, regardless of raw compute potential.

The RTX A1000 is an active production part with a release date of April 2024, a 50 W TDP, and a single-slot form factor. The N1X 48SM is also active but is an integrated graphics processor (IGP) with no power connectors and no TDP listed. The RTX A1000 has a 250 W suggested PSU, making it a drop-in solution for existing workstations. The N1X 48SM, as an IGP, uses the host system's power delivery, but the database does not quantify its draw.

For users who need a working GPU today, the RTX A1000 is the only part with verified performance. The N1X 48SM may have higher theoretical specifications, but without benchmarks or API support, it cannot be recommended for any concrete task. The verdict from the data is unambiguous: the RTX A1000 is the proven performer, while the N1X 48SM remains an unverified entry with no measurable track record.

The bus interface differs as well: PCIe 5.0 x16 for the N1X 48SM, PCIe 4.0 x8 for the RTX A1000.

Architecture Differences

The N1X 48SM is built on Blackwell 2.0 architecture and belongs to the Blackwell IGP (N1x) generation. The RTX A1000 uses Ampere architecture and belongs to the Workstation Ampere (Ax000) generation. These are two distinct design eras, with the N1X 48SM representing a newer integrated design and the RTX A1000 representing a discrete workstation product.

The memory architecture is fundamentally different. The N1X 48SM uses LPDDR5X, a low-power memory typically integrated on the same package or board, while the RTX A1000 uses GDDR6, a dedicated graphics memory. The N1X 48SM's 128 GB capacity is 16 times larger than the RTX A1000's 8 GB, but the RTX A1000 has a higher effective memory clock at 12 Gbps versus 8.5 Gbps.

Core counts show a clear hierarchy. The N1X 48SM has 6144 shading units, 384 TMUs, 48 ROPs, 48 RT cores, and 192 tensor cores. The RTX A1000 has 2304 shading units, 72 TMUs, 32 ROPs, 18 RT cores, and 72 tensor cores. The N1X 48SM has 2.67 times the shading units, 5.33 times the TMUs, 1.5 times the ROPs, 2.67 times the RT cores, and 2.67 times the tensor cores. However, the N1X 48SM's FP32 and FP16 rates are both 28.83 TFLOPS, while the RTX A1000's are 6.737 TFLOPS, a 4.28 times difference.

The RTX A1000 has a defined power profile: 50 W TDP, single-slot, no external power connectors, and a 250 W suggested PSU. The N1X 48SM has no TDP listed, no power connectors, and is classified as an IGP. The RTX A1000 supports four mini-DisplayPort 1.4a outputs, while the N1X 48SM has a single HDMI output. The RTX A1000's API support includes DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the N1X 48SM has no API support listed.

The RTX A1000 has a release date of April 2024, a predecessor of Quadro Turing, and a successor of Workstation Ada. The N1X 48SM has a release date of May 2026, with no predecessor or successor listed. The process nodes differ: 5 nm TSMC for the N1X 48SM, 8 nm Samsung for the RTX A1000. The die size is 382 mm² for the N1X 48SM versus 200 mm² for the RTX A1000.

Where Each One Wins

The RTX A1000 wins in every category where measured performance exists. Its benchmark scores are verified, its API support is complete, and its workstation pedigree is established through the Ampere architecture and the Ax000 generation. The RTX A1000 wins for any task that requires running existing software, as it supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. It also wins for physical deployment, with a single-slot form factor, 50 W TDP, and four mini-DisplayPort outputs, making it suitable for multi-display workstation setups.

The N1X 48SM wins on raw specification counts. It has more shading units, more texture units, more ROPs, more RT cores, and more tensor cores. Its FP32 and FP16 throughput is 28.83 TFLOPS, more than four times the RTX A1000's 6.737 TFLOPS. It has 128 GB of memory, which is 16 times the RTX A1000's 8 GB, and its 273.2 GB/s bandwidth is 1.42 times higher. It also has a faster boost clock at 2346 MHz versus 1462 MHz, and a newer PCIe 5.0 x16 interface versus PCIe 4.0 x8.

The N1X 48SM wins on process technology, using a 5 nm TSMC node versus 8 nm Samsung. It also has a larger die at 382 mm² versus 200 mm², and it belongs to the newer Blackwell 2.0 architecture. The N1X 48SM is an IGP, which means it has no power connectors and no slot width, potentially fitting into systems where a discrete card cannot. However, these wins are theoretical, as the N1X 48SM has no benchmark scores to validate its performance.

The RTX A1000 wins on proven reliability and ecosystem readiness. It has an average benchmark score of 34,207, placing it at the 79th percentile, and it is 0.2% ahead of the RTX A2000 12 GB and the AMD Radeon RX 560 XT in its nearest rival cluster. The N1X 48SM's 50th percentile and zero scores confirm it has no empirical standing. For any user who needs a GPU that works today, the RTX A1000 is the only choice supported by data. For a user who values raw theoretical specifications and is willing to accept an unverified part, the N1X 48SM presents higher numbers on paper, but those numbers have no benchmark confirmation in the database.
