Intel Arc B370 vs NVIDIA N1X 40SM Comparison

Architecture Differences

The Intel Arc B370 and NVIDIA N1X 40SM represent fundamentally different approaches to integrated graphics. The Intel part is built on the Panther Lake chip using the Xe3-LPG architecture, fabricated on a 3 nm process at Intel's own foundry. The NVIDIA N1X 40SM uses the GB20B chip with Blackwell 2.0 architecture, manufactured on a 5 nm process at TSMC. The NVIDIA die measures 382 mm², while the Intel die size is not recorded in the database.

The compute configurations diverge sharply. The Intel Arc B370 packs 1280 shading units, 40 texture mapping units, and 20 raster operation pipelines. It also includes 10 ray tracing cores but no dedicated tensor cores are listed. The NVIDIA N1X 40SM fields 5120 shading units, 320 TMUs, and 40 ROPs, along with 40 ray tracing cores and 160 tensor cores. This gives the NVIDIA part a 4x advantage in shading units, an 8x advantage in TMUs, and a 2x advantage in ROPs.

Clock behavior differs as well. The Intel GPU runs at a 300 MHz base clock with a 2400 MHz boost. The NVIDIA part starts higher at 741 MHz base and boosts to 2346 MHz. Despite the lower base clock, the Intel boost clock is 54 MHz higher than NVIDIA's.

Memory architecture is a major differentiator. The Intel Arc B370 uses system shared memory with a system dependent bandwidth. The NVIDIA N1X 40SM carries 128 GB of LPDDR5X on a 256-bit bus, delivering 273.2 GB/s of bandwidth. The memory clock for the NVIDIA part is 1067 MHz with 8.5 Gbps effective transfer rate. The Intel part's memory type, bus width, and bandwidth are all listed as system shared or dependent.

API support shows a notable split. The Intel Arc B370 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA N1X 40SM lists N/A for DirectX, OpenGL, and Vulkan in the database, which indicates the recorded data does not include API compatibility information for this part.

The bus interface differs: Intel uses IGP while NVIDIA uses PCIe 5.0 x16. Both are integrated graphics packages with no power connectors and no slot width beyond IGP. The Intel TDP is recorded at 25 W, while the NVIDIA TDP is unknown. Display outputs for Intel are portable device dependent, while NVIDIA lists 1x HDMI.

The production status for both is Active. The Intel part has a release date of 2026-01-26, while the NVIDIA part follows on 2026-05-31.

The Verdict

The recorded benchmark data contains a single 3DMark Steel Nomad DX12 score for the Intel Arc B370 at 1184 points. The NVIDIA N1X 40SM has no benchmark entries in the database, so direct numerical comparison is impossible from measured results. The Intel part sits at the 5th percentile of all GPUs, while the NVIDIA part is at the 50th percentile, a positioning that comes from the database's overall distribution rather than any recorded head-to-head test.

Looking at the Intel Arc B370's nearest rivals provides context for its performance tier. The ATI Mobility Radeon HD 5570 averages 1186 points, 0.2% higher. The ATI Radeon HD 5770 averages 1190, 0.5% higher. The AMD Radeon HD 7650M averages 1192, 0.7% higher. The AMD FirePro M2000 averages 1168, which is 1.4% lower than the Intel part. These deltas place the Arc B370 in a narrow band around 1180 points, with all four rivals within roughly 1.4% of its score.

For the NVIDIA N1X 40SM, the absence of benchmark data means any claim about its performance relative to the Intel part would require assumptions outside the recorded facts. The specification sheet, however, shows a much larger compute configuration: 4x the shading units, 8x the texture units, 2x the ROPs, 4x the ray tracing cores, and 160 tensor cores where Intel lists none. The FP32 throughput for NVIDIA is 24.02 TFLOPS versus Intel's 6.144 TFLOPS, a 3.9x difference. Texture rate is 750.7 GTexel/s versus 96.00 GTexel/s, a 7.8x difference. Pixel rate is 93.84 GPixel/s versus 48.00 GPixel/s, a 1.95x difference.

The NVIDIA part also carries dedicated memory with 273.2 GB/s bandwidth, whereas Intel relies on system shared memory with bandwidth dependent on the host platform. This structural advantage in memory bandwidth alone could translate to substantial performance differences in memory-bound workloads, though no recorded benchmark confirms this.

Given the data, the Intel Arc B370 is positioned among legacy desktop and mobile parts from over a decade ago. The NVIDIA N1X 40SM, despite lacking benchmark scores, presents a specification sheet that suggests a far higher performance class. The percentile ranking of 50 for NVIDIA versus 5 for Intel reinforces this interpretation, though it should be noted that the NVIDIA percentile comes from the database's classification, not from measured scores.

For users who require DirectX 12 Ultimate, OpenGL, or Vulkan support, the Intel part has recorded API compatibility. The NVIDIA part has no recorded API support, which could matter for software compatibility. For users who need integrated graphics with high compute throughput, the NVIDIA specification sheet is clearly larger across every measured compute unit.

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark entries between the Intel Arc B370 and the NVIDIA N1X 40SM. The only benchmark score available is the Intel part's 3DMark Steel Nomad DX12 result of 1184 points. The NVIDIA part has an average benchmark score of 0, indicating no measured data exists.

Without direct comparison scores, the analysis must rely on the specification-level differences and the Intel part's positioning against its nearest recorded rivals. The Intel Arc B370's 1184 score places it within a tight cluster: the ATI Mobility Radeon HD 5570 scores 1186 (0.2% higher), the ATI Radeon HD 5770 scores 1190 (0.5% higher), the AMD Radeon HD 7650M scores 1192 (0.7% higher), and the AMD FirePro M2000 scores 1168 (1.4% lower). This indicates the Intel part performs within 1.4% of all four rivals, effectively a four-way statistical tie.

The NVIDIA N1X 40SM's specification sheet suggests a different performance class entirely. Its FP32 throughput of 24.02 TFLOPS is 3.9x the Intel part's 6.144 TFLOPS. The texture rate of 750.7 GTexel/s is 7.8x higher. The pixel rate of 93.84 GPixel/s is 1.95x higher. The memory bandwidth of 273.2 GB/s, assuming the Intel part's system shared memory performs at typical IGP levels, likely exceeds what the Intel configuration can achieve, though the exact system dependent bandwidth is not recorded.

The FP16 comparison shows a narrower gap: Intel delivers 12.29 TFLOPS with a 2:1 ratio, while NVIDIA delivers 24.02 TFLOPS with a 1:1 ratio. The NVIDIA part's FP16 throughput equals its FP32 throughput, indicating full-rate FP16 execution. The Intel part's FP16 is exactly double its FP32, confirming the 2:1 ratio.

The 40 ray tracing cores on the NVIDIA part versus 10 on the Intel part, combined with 160 tensor cores versus none, suggests significant divergence in ray-traced and AI-accelerated workloads. The NVIDIA part also has a 256-bit memory bus feeding 128 GB of LPDDR5X, a configuration that would support large data sets without spilling to system memory.

The recorded data does not allow a definitive performance ranking between the two parts. The Intel Arc B370 has a measured score and clear API support, while the NVIDIA N1X 40SM has a far larger compute specification but no benchmark results. The percentile ranking of 50 for NVIDIA versus 5 for Intel offers the only database-level comparison, and it favors the NVIDIA part substantially, though this ranking derives from the database's classification of all GPUs rather than from any head-to-head test.
