Intel Arc Pro B70 vs NVIDIA N1X 40SM Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results between the Intel Arc Pro B70 and the NVIDIA N1X 40SM. Both products show an average benchmark score of zero in the database, and neither has any nearest rivals listed. This means a direct performance comparison based on measured workloads is not possible from the available information.

What the database does provide is raw compute specification data that allows for theoretical peak throughput comparison. In FP32 operations, the NVIDIA N1X 40SM leads with 24.02 TFLOPS against 22.94 TFLOPS for the Intel Arc Pro B70, a difference of approximately 4.7%. The texture fill rate also favors NVIDIA, with 750.7 GTexel/s versus 716.8 GTexel/s, a margin of about 4.7%. These are close figures, suggesting similar raw shading throughput despite the different architectures.

The Intel Arc Pro B70 counters strongly in pixel throughput. Its 358.4 GPixel/s is nearly four times the 93.84 GPixel/s of the NVIDIA part. This stems from the Intel card's 128 ROPs compared to just 40 ROPs on the NVIDIA design. For rasterization-heavy workloads, the Intel card holds a decisive theoretical advantage.

Memory bandwidth is another significant win for Intel. The Arc Pro B70 delivers 608.0 GB/s through its GDDR6 memory running at 19 Gbps effective, while the NVIDIA N1X 40SM manages 273.2 GB/s from LPDDR5X at 8.5 Gbps effective. That is a 2.2x bandwidth advantage for Intel. However, the NVIDIA part offers 128 GB of memory versus 32 GB, a fourfold capacity lead that matters for large dataset residency.

FP16 compute presents an interesting split. The Intel card achieves 45.88 TFLOPS using a 2:1 ratio, effectively doubling its FP32 rate. The NVIDIA card holds at 24.02 TFLOPS with a 1:1 ratio, meaning it does not gain throughput in half-precision operations. For workloads that can utilize FP16, Intel shows a 1.9x theoretical advantage.

Where Each One Wins

The Intel Arc Pro B70 is positioned for compute workloads that benefit from high pixel throughput and fast memory bandwidth. Its 128 ROPs and 608.0 GB/s bandwidth support heavy fragment shading and large texture streaming. The 32 GB GDDR6 pool, while smaller than NVIDIA's, operates at more than double the bandwidth, which helps latency-sensitive tasks. The dual-slot design with a 230 W TDP and a single 8-pin power connector indicates a conventional add-in card meant for workstation or professional use. Its PCIe 5.0 x16 interface matches the NVIDIA part, but the Intel card supports modern graphics APIs including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, making it suitable for mainstream graphics software.

The NVIDIA N1X 40SM is an integrated graphics processor (IGP) with no power connectors and no listed TDP. Its 128 GB LPDDR5X memory capacity is the standout feature, allowing entire datasets to remain on-chip without host memory transfers. The 40 RT cores and 160 tensor cores give it specialized hardware for ray tracing and AI inference. The 1:1 FP16 ratio suggests the architecture prioritizes consistent throughput across precisions rather than burst performance. Its Blackwell 2.0 architecture and GB20B chip are newer than Intel's Xe2-HPG design, but the card lists no API support in the database, which limits its applicability to standard graphics workloads.

For pure rasterization and memory bandwidth, the Intel part wins. For memory capacity and tensor throughput, the NVIDIA part wins. The recorded data shows no overlap in these strengths, so the choice depends entirely on workload requirements.

Architecture Differences

The Intel Arc Pro B70 uses the BMG-G31 chip built on TSMC's 5 nm process with a die size of 368 mm². It belongs to the Xe2-HPG architecture, specifically the Battlemage Pro Series generation. The GPU packs 4096 shading units, 256 texture mapping units, and 128 ROPs. Ray tracing is handled by 32 dedicated RT cores. The design is a traditional discrete graphics card with a dual-slot cooler and a rated TDP of 230 W.

The NVIDIA N1X 40SM uses the GB20B chip, also on TSMC's 5 nm process, with a slightly larger die at 382 mm². It belongs to the Blackwell 2.0 architecture in the Blackwell IGP generation. The chip contains 5120 shading units, 320 texture units, but only 40 ROPs. It has 40 RT cores and 160 tensor cores, which is more than Intel's RT core count and adds a tensor core array that Intel's card lacks entirely. The NVIDIA part is an integrated graphics processor with no slot width, no power connectors, and no listed TDP, which aligns with its IGP classification.

Clock behavior differs markedly. The Intel card runs at a 2280 MHz base and 2800 MHz boost, while the NVIDIA part starts at 741 MHz base and reaches 2346 MHz boost. The lower base clock on NVIDIA suggests power management that keeps idle and light loads at minimal frequency, ramping up only when needed. Intel's higher base clock indicates a more aggressive always-on performance profile, consistent with a desktop discrete card.

Memory architecture also differs. Intel uses 32 GB of GDDR6 on a 256-bit bus at 19 Gbps effective, yielding 608.0 GB/s. NVIDIA uses 128 GB of LPDDR5X on a 256-bit bus at 8.5 Gbps effective, yielding 273.2 GB/s. Both use the same bus width, but the memory type and speed create the bandwidth gap. LPDDR5X is typically lower power, which suits an IGP, while GDDR6 provides higher throughput for a discrete card.

API support is another major divergence. Intel lists DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. NVIDIA lists "N/A" for all three APIs. This makes the Intel card broadly compatible with existing graphics software, while the NVIDIA part's API status is unlisted, potentially limiting it to proprietary or compute-only use cases.

The Verdict

The Intel Arc Pro B70 is the choice for standard graphics workloads. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, which makes it compatible with current games and professional graphics applications. Its 358.4 GPixel/s pixel rate and 608.0 GB/s bandwidth provide strong rasterization performance. The 45.88 TFLOPS FP16 throughput doubles its FP32 rate, offering compute headroom for AI and scientific tasks that use half precision. The 32 GB memory capacity is sufficient for most workstation tasks, and the dual-slot form factor with a single 8-pin connector fits standard desktop builds. The launch MSRP is 949 USD.

The NVIDIA N1X 40SM is the choice for memory-capacity-bound workloads. Its 128 GB LPDDR5X pool is four times larger than Intel's, which allows entire large datasets to reside on the GPU. The 160 tensor cores provide dedicated AI inference hardware that the Intel card lacks. The 40 RT cores exceed Intel's 32, potentially offering stronger ray tracing throughput. However, the lack of listed API support and the IGP form factor restrict its use to systems that can accommodate an integrated processor without standard graphics software compatibility.

The data shows a clear tradeoff: Intel wins on bandwidth, pixel rate, FP16 compute, and software compatibility. NVIDIA wins on memory capacity, shading units, tensor cores, and RT core count. Neither card dominates the other across all metrics. The decision rests on whether the workload needs high-speed memory access or large memory residency. For rendering and general GPU compute, the Intel Arc Pro B70 delivers a complete package. For AI inference with massive model footprints, the NVIDIA N1X 40SM offers unmatched capacity. The absence of direct benchmark scores means these conclusions rely on specification analysis rather than measured performance.
