Intel Arc B570 vs NVIDIA N1X 48SM Comparison

Intel Arc B570 vs NVIDIA N1X 48SM

The Intel Arc B570 and NVIDIA N1X 48SM occupy very different positions in the database. The Arc B570 is a discrete add-in board built on the Xe2-HPG architecture, while the N1X 48SM is an integrated graphics processor (IGP) based on Blackwell 2.0. The recorded data shows a substantial gap in raw compute specifications, but the N1X 48SM carries a large memory pool and a different design intent. The Arc B570 has an average benchmark score of 20,556 across the recorded tests, placing it at the 65th percentile among all GPUs. The N1X 48SM has no recorded benchmark entries, an average score of 0, and sits at the 50th percentile by default classification. Direct head-to-head benchmark comparisons are absent from the database, so the analysis below relies on the specification differences and the Arc B570’s measured performance relative to its nearest rivals.

Where Each One Wins

The Arc B570 wins in every measurable performance category because the N1X 48SM has no benchmark results in the database. The Arc B570’s recorded tests include 3DMark Steel Nomad DX12 with a score of 2,649, Geekbench OpenCL at 83,514, Geekbench Vulkan at 96,844, and multiple Passmark tests. Its Passmark G3D score is 14,195, while Passmark GPU Compute reaches 7,281. These numbers place the Arc B570 near a tight cluster of competitors. The nearest rival, the Intel Arc A750, has an average score of 20,582, which is 0.1% higher than the Arc B570’s 20,556. The NVIDIA GeForce RTX 3070 Mobile averages 20,534, just 0.1% lower. The NVIDIA Quadro M4000M sits at 20,480, 0.4% below, and the AMD Radeon R9 M390X scores 20,662, 0.5% above. The Arc B570 therefore lands in a narrow performance band where no rival is more than half a percent away in either direction.

The N1X 48SM wins in memory capacity and interface breadth. It carries 128 GB of LPDDR5X memory on a 256-bit bus, compared to the Arc B570’s 10 GB of GDDR6 on a 160-bit bus. The N1X 48SM also uses PCIe 5.0 x16, while the Arc B570 uses PCIe 4.0 x8. The N1X 48SM has more shading units, texture mapping units, ray tracing cores, and tensor cores than the Arc B570. It has 6,144 shading units, 384 TMUs, 48 RT cores, and 192 tensor cores. The Arc B570 has 2,304 shading units, 144 TMUs, 18 RT cores, and no tensor core count listed. The N1X 48SM also delivers higher FP32 throughput at 28.83 TFLOPS compared to 11.52 TFLOPS for the Arc B570. However, the N1X 48SM has no benchmark entries, so its theoretical advantages are not reflected in any measured test result.

Architecture Differences

The two processors come from different architectural generations and design philosophies. The Intel Arc B570 uses the Xe2-HPG architecture, which is part of the Battlemage generation, specifically the Arc 5 tier. Its chip is labeled BMG-G21, and it is manufactured on a 5 nm process at TSMC. The die size is 272 mm², and the transistor count is 19,600 million, yielding a transistor density of 72.1 million per mm². The NVIDIA N1X 48SM uses the Blackwell 2.0 architecture, belonging to the Blackwell IGP generation under the N1x name. Its chip is designated GB20B, also built on a 5 nm TSMC process, but the die is larger at 382 mm². The transistor count for the N1X 48SM is listed as unknown, and no transistor density is provided.

The memory subsystems differ in type and configuration. The Arc B570 uses 10 GB of GDDR6 with a 160-bit bus, producing 380.0 GB/s of bandwidth. The N1X 48SM uses 128 GB of LPDDR5X with a 256-bit bus, producing 273.2 GB/s of bandwidth. Despite the wider bus, the N1X 48SM has lower total bandwidth because its memory operates at a lower effective speed. The Arc B570’s memory clock is listed as 2375 MHz with 19 Gbps effective data rate. The N1X 48SM’s memory clock is 1067 MHz with 8.5 Gbps effective. Clock speeds for the GPU cores also diverge sharply. The Arc B570 runs at a fixed 2500 MHz for both base and boost. The N1X 48SM has a base clock of 741 MHz and a boost clock of 2346 MHz.

The compute resources are distributed differently. The Arc B570 has 2,304 shading units, 144 TMUs, 80 ROPs, and 18 RT cores. The N1X 48SM has 6,144 shading units, 384 TMUs, 48 ROPs, and 48 RT cores. The N1X 48SM has 192 tensor cores, while the Arc B570 lists no tensor core count. The FP32 output for the N1X 48SM is 28.83 TFLOPS, more than double the Arc B570’s 11.52 TFLOPS. FP16 performance also differs: the Arc B570 achieves 23.04 TFLOPS with a 2:1 ratio, while the N1X 48SM achieves 28.83 TFLOPS with a 1:1 ratio. Pixel and texture rates follow similar patterns. The Arc B570 reaches 200.0 GPixel/s and 360.0 GTexel/s. The N1X 48SM reaches 112.6 GPixel/s and 900.9 GTexel/s. The N1X 48SM has a much higher texture rate but a lower pixel rate.

Power and physical design are also distinct. The Arc B570 has a TDP of 150 W, uses a dual-slot cooler, requires a single 8-pin power connector, and suggests a 450 W power supply. The N1X 48SM has an unknown TDP, an IGP form factor, no power connectors, and no suggested PSU rating. The Arc B570 is a 272 mm long, 115 mm tall card. The N1X 48SM has no listed dimensions. The Arc B570 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X 48SM lists N/A for DirectX, OpenGL, and Vulkan support. The Arc B570 was released on January 15, 2025, and has a launch MSRP of 219 USD. The N1X 48SM has a release date of May 31, 2026, and no MSRP is listed.

Head-to-Head Benchmarks

No direct head-to-head benchmark entries exist in the database for these two GPUs. The comparison therefore rests on the Arc B570’s recorded results and the N1X 48SM’s absence of any measured scores. The Arc B570’s strongest recorded result is in Geekbench Vulkan, where it scores 96,844. Its Geekbench OpenCL score is 83,514. In 3DMark Steel Nomad DX12, it scores 2,649. Passmark results show a G3D score of 14,195, a GPU Compute score of 7,281, a G2D score of 661, a DirectX 9 score of 164, a DirectX 11 score of 118, a DirectX 12 score of 72, and a DirectX 10 score of 65. These are the only benchmark data points available for either GPU.

The Arc B570’s average score of 20,556 places it within a tight competitive cluster. The Intel Arc A750 is the closest rival at 20,582, a difference of 0.1%. The NVIDIA GeForce RTX 3070 Mobile is equally close at 20,534, also 0.1% away. The AMD Radeon R9 M390X is 0.5% higher, and the NVIDIA Quadro M4000M is 0.4% lower. These margins indicate that the Arc B570 delivers performance statistically indistinguishable from its nearest competitors in the database’s aggregate scoring. The N1X 48SM, by contrast, has no scores to compare, so its theoretical specification advantages cannot be verified through measured results.

The specification sheet favors the N1X 48SM in several raw numbers. It has more than double the FP32 throughput, more shading units, more TMUs, more RT cores, and 192 tensor cores. It also has 128 GB of memory, which is more than twelve times the Arc B570’s 10 GB. However, the N1X 48SM has lower memory bandwidth, a lower pixel rate, and a lower base clock. The Arc B570 has a higher boost clock at 2500 MHz versus 2346 MHz, and its memory bandwidth of 380.0 GB/s exceeds the N1X 48SM’s 273.2 GB/s. The Arc B570 also has API support for modern graphics standards, while the N1X 48SM lists none.

The database records no wins for either GPU in a head-to-head comparison, as the winsA and winsB fields are both 0. The percentile ranking shows the Arc B570 at the 65th percentile among all GPUs, while the N1X 48SM sits at the 50th percentile. The average benchmark score of 20,556 for the Arc B570 reflects actual measured performance across ten tests. The N1X 48SM’s average score of 0 reflects the absence of recorded measurements. For any user relying on benchmark data, the Arc B570 provides a complete set of results, while the N1X 48SM offers only its specification sheet. The specification sheet shows a GPU with high theoretical compute and large memory capacity, but no measured validation exists in the database.
