Intel Arc B570 vs NVIDIA N1 20SM Comparison

The Verdict

The recorded data presents a clear contrast between two very different products. The Intel Arc B570 is a discrete desktop graphics card with a full suite of benchmark results, while the NVIDIA N1 20SM is an integrated graphics processor (IGP) with no recorded benchmark scores in the database. The Arc B570 holds an average benchmark score of 20556, placing it at the 65th percentile of all GPUs. The N1 20SM, by contrast, has an average benchmark score of 0 and sits at the 50th percentile, a position that reflects its status as a product without measured performance data rather than actual performance parity.

The Intel Arc B570 is the only option with verifiable performance metrics. Its nearest rivals include the NVIDIA GeForce RTX 3070 Mobile (average score 20534, a 0.1% difference), the Intel Arc A750 (average score 20582, a 0.1% difference in the other direction), the NVIDIA Quadro M4000M (average score 20480, 0.4% difference), and the AMD Radeon R9 M390X (average score 20662, 0.5% difference). These deltas are minimal, indicating that the Arc B570 performs within a tight band around these established products.

The NVIDIA N1 20SM cannot be evaluated for gaming or compute performance because the database contains no benchmark entries for it. Its specifications suggest a different purpose: it is an IGP with 128 GB of LPDDR5X memory on a 256-bit bus, 80 tensor cores, and 20 RT cores. It targets a market segment where the Arc B570 does not compete directly. The decision between these two products hinges on whether the user requires a proven discrete GPU with measured results or an integrated solution with unified memory and tensor core capabilities.

Architecture Differences

The Intel Arc B570 uses the BMG-G21 chip built on the Xe2-HPG architecture, part of the Battlemage generation (Arc 5). It is fabricated on a 5 nm process at TSMC with 19,600 million transistors on a 272 mm² die, yielding a transistor density of 72.1 million per mm². The NVIDIA N1 20SM uses the GB20B chip based on Blackwell 2.0 architecture, part of the Blackwell IGP (N1x) generation. It is also fabricated on a 5 nm process at TSMC, but its die size is 382 mm², larger than the Arc B570. The N1 20SM's transistor count is listed as unknown.

Memory configurations differ substantially. The Arc B570 has 10 GB of GDDR6 on a 160-bit bus, delivering 380.0 GB/s of bandwidth. The N1 20SM has 128 GB of LPDDR5X on a 256-bit bus, delivering 273.2 GB/s. The N1 20SM's memory pool is over twelve times larger, but its bandwidth is lower by roughly 28%. This suggests the N1 20SM is designed for large working sets in AI or data processing tasks rather than bandwidth-intensive rendering.

The shader configurations are comparable in raw count. The Arc B570 has 2304 shading units, 144 TMUs, and 80 ROPs, with 18 RT cores. The N1 20SM has 2560 shading units, 160 TMUs, and only 24 ROPs, with 20 RT cores and 80 tensor cores. The N1 20SM's ROP count is a fraction of the Arc B570's, which directly impacts pixel throughput: the Arc B570 achieves 200.0 GPixel/s versus 56.30 GPixel/s for the N1 20SM. Texture rates are closer, at 360.0 GTexel/s for the Arc B570 and 375.4 GTexel/s for the N1 20SM.

Clock speeds reveal different design philosophies. The Arc B570 runs at a fixed 2500 MHz base and boost, with memory at 2375 MHz (19 Gbps effective). The N1 20SM has a base clock of 741 MHz and a boost clock of 2346 MHz, a wide spread that suggests aggressive power management typical of integrated parts. Its memory runs at 1067 MHz (8.5 Gbps effective). FP32 throughput is nearly identical: 11.52 TFLOPS for the Arc B570 versus 12.01 TFLOPS for the N1 20SM. FP16 differs sharply: the Arc B570 delivers 23.04 TFLOPS with a 2:1 ratio, while the N1 20SM delivers 12.01 TFLOPS with a 1:1 ratio.

The Arc B570 is a dual-slot card with a 272 mm length, a 150 W TDP, a single 8-pin power connector, and a suggested 450 W PSU. It connects via PCIe 4.0 x8 and outputs 1x HDMI 2.1a and 3x DisplayPort 2.1. The N1 20SM is an IGP with no power connector, no slot width, and a PCIe 5.0 x16 interface. It has a single HDMI output. API support also diverges: the Arc B570 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the N1 20SM lists N/A for DirectX, OpenGL, and Vulkan, indicating it is not positioned as a conventional graphics API device.

Where Each One Wins

The Intel Arc B570 wins in every measurable benchmark category because it is the only product with recorded scores. Its 3DMark Steel Nomad DX12 score of 2649, Geekbench OpenCL score of 83514, and Geekbench Vulkan score of 96844 establish a performance baseline. PassMark results include DirectX 10 at 65, DirectX 11 at 118, DirectX 12 at 72, DirectX 9 at 164, G2D at 661, G3D at 14195, and GPU compute at 7281. The N1 20SM has no scores in any of these tests.

The N1 20SM wins on memory capacity, with 128 GB versus 10 GB. It also has more shading units (2560 versus 2304), more TMUs (160 versus 144), more RT cores (20 versus 18), and 80 tensor cores where the Arc B570 has none listed. Its texture rate is higher at 375.4 GTexel/s versus 360.0 GTexel/s. It uses a PCIe 5.0 x16 interface compared to the Arc B570's PCIe 4.0 x8. These are architectural advantages, but they lack benchmark confirmation.

The Arc B570 is the choice for rasterization, pixel fill, and graphics API workloads. Its ROP count of 80 versus 24 and pixel rate of 200.0 GPixel/s versus 56.30 GPixel/s give it a decisive edge in traditional rendering. The N1 20SM is the choice for tensor-heavy workloads and large memory footprints, based strictly on its specification sheet. The FP16 data reinforces this: the Arc B570's 2:1 FP16 rate of 23.04 TFLOPS suits graphics shading, while the N1 20SM's 1:1 rate of 12.01 TFLOPS indicates it treats FP16 as a compute precision rather than a shader acceleration path.

Head-to-Head Benchmarks

No head-to-head benchmark entries exist between the Intel Arc B570 and the NVIDIA N1 20SM. The database records zero wins for either product in direct comparison. The only available performance data comes from the Arc B570's individual benchmark suite.

The Arc B570's strongest recorded results are in compute-oriented tests. Its Geekbench Vulkan score of 96844 exceeds its OpenCL score of 83514 by roughly 16%. In PassMark tests, the G3D score of 14195 dominates the other graphics tests: DirectX 9 scores 164, DirectX 11 scores 118, DirectX 12 scores 72, and DirectX 10 scores 65. The GPU compute score of 7281 is about half the G3D score.

The 3DMark Steel Nomad DX12 score of 2649 represents the only modern gaming benchmark in the dataset. Comparing it to the PassMark G3D score of 14195 shows how different test methodologies produce different perspectives on the same hardware. The Arc B570's average benchmark score of 20556 places it at the 65th percentile of all GPUs, which means it outperforms roughly two-thirds of the database population.

The nearest rival data contextualizes the Arc B570's position. The NVIDIA GeForce RTX 3070 Mobile averages 20534, only 0.1% below the Arc B570. The Intel Arc A750 averages 20582, only 0.1% above. These two products are effectively tied with the Arc B570. The NVIDIA Quadro M4000M sits 0.4% lower at 20480, and the AMD Radeon R9 M390X sits 0.5% higher at 20662. The spread from the lowest to highest rival is less than one percentage point, indicating that the Arc B570 occupies a crowded performance tier.

The NVIDIA N1 20SM cannot be placed in this hierarchy because it lacks scores. Its specification sheet shows a different design target: 2560 shading units, 160 TMUs, 80 tensor cores, and 128 GB of memory. The Arc B570 counters with 80 ROPs, a 200.0 GPixel/s pixel rate, and 380.0 GB/s of memory bandwidth. The FP32 figures are close enough that compute workloads might favor the N1 20SM by a narrow margin, but the absence of measured data prevents any confirmation. The Arc B570 remains the only product in this comparison with verified performance, and it holds a 65th percentile standing on that basis.
