Intel Arc Pro B70 vs NVIDIA N1 16SM Comparison

Head-to-Head Benchmarks

The recorded database contains no head-to-head benchmark entries for the Intel Arc Pro B70 and NVIDIA N1 16SM. Both GPUs hold a percentile rank of 50 against all GPUs in the database, which places them at the midpoint of the distribution. Their average benchmark scores are zero, indicating that no standardized test results have been logged for either part. Without direct measurement data, the comparison must rely entirely on the architectural and specification fields recorded for each device.

The absence of benchmark scores is notable for a workstation-class GPU like the Intel Arc Pro B70 and an integrated part like the NVIDIA N1 16SM. The Arc Pro B70 is a discrete dual-slot card, while the N1 16SM is an IGP (integrated graphics processor) with no slot width, no power connectors, and no physical dimensions recorded. The database shows zero wins for either side in the head-to-head category, which confirms that no comparative testing has been completed. The analysis below therefore interprets the recorded specification differences and their expected performance implications, based strictly on the numbers present in the database.

Architecture Differences

The Intel Arc Pro B70 uses the BMG-G31 chip built on the Xe2-HPG architecture, part of the Battlemage Pro Series generation. The NVIDIA N1 16SM uses the GB20B chip built on the Blackwell 2.0 architecture, part of the Blackwell IGP N1x generation. Both are fabricated on a 5 nm process at TSMC, and both use a PCIe 5.0 x16 bus interface. The Intel die measures 368 mm², while the NVIDIA die measures 382 mm². Transistor counts and transistor density are recorded as unknown for both parts.

The Arc Pro B70 has 4096 shading units, 256 texture mapping units, 128 render output units, and 32 ray tracing cores. The N1 16SM has 2048 shading units, 128 TMUs, 24 ROPs, and 16 ray tracing cores. The NVIDIA part additionally has 64 tensor cores, while the Intel part has no tensor core count recorded. The Intel GPU offers a 2:1 FP16 ratio with 45.88 TFLOPS, while the NVIDIA GPU has a 1:1 FP16 ratio at 9.609 TFLOPS. In FP32, the Arc Pro B70 delivers 22.94 TFLOPS versus 9.609 TFLOPS for the N1 16SM.

Memory architecture differs substantially. The Intel card has 32 GB of GDDR6 on a 256 bit bus, with 608.0 GB/s of bandwidth and memory clocked at 2375 MHz (19 Gbps effective). The NVIDIA IGP has 128 GB of LPDDR5X on a 256 bit bus, with 273.2 GB/s of bandwidth and memory clocked at 1067 MHz (8.5 Gbps effective). The Intel part has a base clock of 2280 MHz and a boost clock of 2800 MHz, while the NVIDIA part has a base clock of 741 MHz and a boost clock of 2346 MHz. Pixel rate for the Arc Pro B70 is 358.4 GPixel/s, versus 56.30 GPixel/s for the N1 16SM. Texture rate is 716.8 GTexel/s for Intel and 300.3 GTexel/s for NVIDIA.

API support also diverges. The Intel card supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA IGP has no API support recorded, with DirectX, OpenGL, and Vulkan all listed as N/A. Display outputs differ as well: the Arc Pro B70 has 1x HDMI 2.1a and 3x DisplayPort 2.1, while the N1 16SM has only 1x HDMI with no version specified.

Where Each One Wins

The Intel Arc Pro B70 wins decisively in raw compute throughput. Its FP32 output of 22.94 TFLOPS is more than double the 9.609 TFLOPS of the N1 16SM. The FP16 figure of 45.88 TFLOPS at a 2:1 ratio gives the Intel part a 4.77x advantage over the NVIDIA part's 9.609 TFLOPS at a 1:1 ratio. The Arc Pro B70 also leads in pixel rate at 358.4 GPixel/s, which is 6.37x higher than the N1 16SM's 56.30 GPixel/s. Texture rate follows the same pattern, with 716.8 GTexel/s versus 300.3 GTexel/s, a 2.39x margin.

Memory bandwidth strongly favors the Intel card. The 608.0 GB/s of the Arc Pro B70 is 2.23x the 273.2 GB/s of the N1 16SM. The Intel part also has a much higher memory clock at 2375 MHz versus 1067 MHz. However, the NVIDIA IGP holds a capacity advantage with 128 GB versus 32 GB, which is 4x more memory. The NVIDIA part also has 64 tensor cores, which the Intel card lacks entirely, giving the N1 16SM a specialized advantage in workloads that use tensor operations, provided software support exists.

The NVIDIA N1 16SM has a lower power footprint by design. Its TDP is unknown, but it uses no power connectors and has no suggested PSU rating. The Intel Arc Pro B70 has a TDP of 230 W, requires a single 8-pin power connector, and suggests a 550 W PSU. The NVIDIA part is an IGP, meaning it integrates into a system without discrete card dimensions. The Intel card measures 267 mm in length, 110 mm in height, and 39 mm in width. The N1 16SM has no physical dimensions recorded.

In terms of release timing, the Intel Arc Pro B70 has a release date of 2026-03-25, while the NVIDIA N1 16SM has a release date of 2026-05-31. The NVIDIA part is marked as Active in production status, while the Intel part has no production status recorded. The Intel card has a launch MSRP of 949 USD, while the NVIDIA part has no launch MSRP recorded.
