Q: How does the physical form factor differ?

A: The Intel Arc Pro B60 Dual is a dual-slot, 300 mm long, 110 mm tall, 40 mm wide card with a 1x 16-pin power connector. The NVIDIA N1X 40SM is an IGP (integrated graphics processor) with no dimensions listed, no power connectors, and a single HDMI output.

Architecture Differences

The Intel Arc Pro B60 Dual and NVIDIA N1X 40SM represent fundamentally different design philosophies within the same manufacturing process. Both use TSMC's 5 nm node, but their chip layouts diverge sharply.

The Intel chip, BMG-G21, measures 272 mm² and packs 19,600 million transistors, resulting in a transistor density of 72.1M per mm². The NVIDIA GB20B chip is larger at 382 mm², but its transistor count is listed as unknown in the database. This size difference suggests the NVIDIA die allocates more area to memory controllers and tensor hardware, consistent with its 160 tensor cores versus none listed for Intel.

Shader core counts differ significantly. The NVIDIA N1X 40SM has 5,120 shading units, 320 TMUs, and 40 ROPs. The Intel Arc Pro B60 Dual has 2,560 shading units, 160 TMUs, and 80 ROPs. The NVIDIA GPU doubles the shader and texture units, while Intel has twice the ROP count. This indicates NVIDIA prioritizes raw shader throughput, while Intel emphasizes pixel fill and rasterization.

Ray tracing hardware also differs. The NVIDIA part has 40 RT cores, double the Intel card's 20 RT cores. Tensor core counts show a stark contrast: NVIDIA integrates 160 tensor cores, while the Intel specification lists none. This makes the NVIDIA N1X 40SM substantially more capable for AI-accelerated workloads, assuming software support exists.

Clock behavior reveals another architectural split. The Intel GPU runs a 2000 MHz base and 2400 MHz boost, while the NVIDIA part runs a low 741 MHz base but boosts to 2346 MHz. The wide base-to-boost delta on NVIDIA suggests aggressive power management, whereas Intel maintains a high sustained clock floor.

Memory architecture differs completely. Intel uses 24 GB GDDR6 on a 192-bit bus at 2375 MHz, achieving 456.0 GB/s. NVIDIA uses 128 GB LPDDR5X on a 256-bit bus at 1067 MHz, achieving 273.2 GB/s. The NVIDIA solution prioritizes capacity for large datasets, while Intel prioritizes bandwidth for texture-heavy workloads.

The API support gap is notable. Intel lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. NVIDIA lists N/A for all three APIs, reflecting its IGP classification rather than a traditional discrete GPU. The bus interface also differs: Intel uses PCIe 5.0 x8, while NVIDIA uses PCIe 5.0 x16.

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark scores for these two GPUs. Without measured performance data, the comparison must rely on the architectural specifications and derived throughput values.

FP32 compute shows a clear NVIDIA advantage. The N1X 40SM delivers 24.02 TFLOPS, while the Arc Pro B60 Dual delivers 12.29 TFLOPS. This puts NVIDIA at roughly double the FP32 throughput, a decisive margin for general compute and shader-bound workloads. The texture rate follows a similar pattern: NVIDIA achieves 750.7 GTexel/s versus Intel's 384.0 GTexel/s, a 95% advantage.

Pixel rate reverses the trend. Intel achieves 192.0 GPixel/s, while NVIDIA manages 93.84 GPixel/s. Intel's higher ROP count and faster clock speed drive this 105% advantage in fill-rate-limited scenarios. This suggests Intel holds a lead in traditional rasterization at high resolutions, assuming the API stack supports those workloads.

FP16 performance tells a nuanced story. Intel lists 24.58 TFLOPS with a 2:1 ratio, meaning it doubles its FP32 rate. NVIDIA lists 24.02 TFLOPS with a 1:1 ratio, meaning FP16 matches FP32. For FP16 workloads, the two GPUs are effectively tied at roughly 24 TFLOPS, though the architectures achieve this through different means.

Memory bandwidth favors Intel at 456.0 GB/s versus 273.2 GB/s, a 67% advantage. This impacts texture streaming, frame buffer operations, and any bandwidth-sensitive compute. NVIDIA counters with 128 GB capacity versus 24 GB, a 5.33x capacity advantage, which matters for large model inference or datasets that exceed 24 GB.

The clock speeds shape real-world behavior. Intel's 2400 MHz boost versus NVIDIA's 2346 MHz boost is close, but Intel's 2000 MHz base versus 741 MHz base suggests sustained performance under load favors Intel if power delivery allows. The NVIDIA part's low base clock implies it relies heavily on boost behavior.

Neither GPU has recorded benchmark scores, percentile ranks, or nearest rivals in the database. Both sit at the 50th percentile versus all GPUs, with average benchmark scores of zero. This means the comparison above is purely specification-driven.

The Verdict

The recorded data presents two GPUs with opposite strengths. The NVIDIA N1X 40SM leads decisively in FP32 compute, texture rate, shader units, TMUs, RT cores, tensor cores, and memory capacity. The Intel Arc Pro B60 Dual leads in pixel rate, ROPs, memory bandwidth, clock speeds, and API support.

The NVIDIA part is built for compute-heavy and AI-accelerated tasks. Its 24.02 TFLOPS FP32, 160 tensor cores, and 128 GB memory position it for large-scale inference, scientific simulation, and data-parallel workloads. The 5.33x memory capacity advantage means datasets that fit entirely in 128 GB avoid PCIe transfers, a critical factor for certain server or workstation tasks.

The Intel part is built for graphics output. Its 192.0 GPixel/s pixel rate, 456.0 GB/s bandwidth, and full DirectX 12 Ultimate support make it a conventional discrete GPU for rendering pipelines. The 4x mini-DisplayPort 2.1 outputs and PCIe 5.0 x8 interface suit multi-display professional environments.

The NVIDIA listing shows N/A for DirectX, OpenGL, and Vulkan, which means traditional graphics API workloads may not be supported at all. The single HDMI output and IGP form factor reinforce this: the N1X 40SM is not a standard graphics card. The Intel card, with its dual-slot design, 300 mm length, 400 W TDP, and 800 W suggested PSU, is a conventional add-in board.

Release timing also separates them. Intel launched on 2025-09-04 with a launch MSRP of 1,199 USD. NVIDIA's release date is 2026-05-31 with no launch MSRP recorded. The NVIDIA part is newer, but its IGP classification and missing API support limit direct comparison.

Where Each One Wins

Intel Arc Pro B60 Dual wins in: Pixel fill rate (192.0 GPixel/s versus 93.84 GPixel/s), memory bandwidth (456.0 GB/s versus 273.2 GB/s), ROP count (80 versus 40), base clock (2000 MHz versus 741 MHz), API compatibility (DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.4 versus N/A), display connectivity (4x mini-DisplayPort 2.1 versus 1x HDMI), and standard graphics card form factor with dual-slot cooling and 1x 16-pin power.

NVIDIA N1X 40SM wins in: FP32 compute (24.02 TFLOPS versus 12.29 TFLOPS), texture rate (750.7 GTexel/s versus 384.0 GTexel/s), shader units (5120 versus 2560), TMUs (320 versus 160), RT cores (40 versus 20), tensor cores (160 versus none listed), memory capacity (128 GB versus 24 GB), memory bus width (256 bit versus 192 bit), and PCIe interface width (x16 versus x8).

Use-case split: The Intel Arc Pro B60 Dual suits traditional graphics rendering, multi-display professional output, and bandwidth-sensitive workloads where pixel throughput and API coverage matter. Its 400 W TDP and 800 W suggested PSU indicate a standalone workstation card. The NVIDIA N1X 40SM suits compute-heavy, AI-accelerated, and memory-capacity-bound tasks. Its 128 GB memory and 160 tensor cores target large-model workloads, while its IGP form factor and single HDMI output exclude it from conventional multi-monitor graphics setups. The absence of DirectX, OpenGL, and Vulkan support in the database means any graphics API workload defaults to the Intel card.
