Intel Arc Pro B65 vs NVIDIA N1X 48SM Comparison

Head-to-Head Benchmarks

The recorded data contains no head-to-head benchmark entries for the Intel Arc Pro B65 versus the NVIDIA N1X 48SM. Both GPUs show zero benchmark scores, zero wins in the comparison, and no nearest rivals with performance deltas. This absence of measured performance data means the comparison rests entirely on architectural specifications, memory subsystems, and compute capabilities rather than empirical test results.

What the data does show is a substantial divergence in raw compute throughput. The NVIDIA N1X 48SM delivers 28.83 TFLOPS of FP32 performance, which is 135% higher than the Intel Arc Pro B65's 12.29 TFLOPS. The gap in FP16 is even more pronounced in one direction: the NVIDIA part achieves 28.83 TFLOPS at a 1:1 ratio, while the Intel part reaches 24.58 TFLOPS at a 2:1 ratio. This means the NVIDIA GPU exceeds the Intel GPU's FP16 throughput by roughly 17%, but the Intel part's FP16 figure requires the 2:1 rate, effectively halving its throughput when operating at full precision.

Texture throughput also favors the NVIDIA part decisively. The N1X 48SM processes 900.9 GTexel/s against the Arc Pro B65's 384.0 GTexel/s, a 135% advantage. Pixel throughput reverses the trend: the Intel GPU renders 192.0 GPixel/s, while the NVIDIA part manages 112.6 GPixel/s, giving Intel a 71% lead in pixel fill rate.

Where Each One Wins

The Intel Arc Pro B65 wins in pixel fill rate, delivering 192.0 GPixel/s compared to the NVIDIA N1X 48SM's 112.6 GPixel/s. This advantage suggests the Intel part is better suited for workloads that stress rasterization output, such as high-resolution framebuffer writes or heavy overdraw scenarios. The Intel GPU also operates at a much higher base clock of 2400 MHz versus 741 MHz on the NVIDIA part, and its boost clock matches its base at 2400 MHz, while the NVIDIA GPU boosts to 2346 MHz. The Intel part also carries a full set of graphics API support including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, whereas the NVIDIA N1X 48SM lists no API support in the database.

The NVIDIA N1X 48SM wins decisively in compute throughput, both FP32 and FP16. Its 28.83 TFLOPS FP32 figure more than doubles the Intel part's 12.29 TFLOPS. Texture rate also goes to NVIDIA at 900.9 GTexel/s versus 384.0 GTexel/s. The NVIDIA GPU further dominates in shading units with 6144 versus 2560, texture mapping units at 384 versus 160, ray tracing cores at 48 versus 20, and tensor cores at 192 versus zero on the Intel side. Memory capacity strongly favors NVIDIA as well, with 128 GB of LPDDR5X against 32 GB of GDDR6.

The NVIDIA part's memory bandwidth of 273.2 GB/s is lower than Intel's 608.0 GB/s, but the NVIDIA GPU pairs its 256-bit bus with LPDDR5X at 1067 MHz (8.5 Gbps effective), while Intel uses GDDR6 at 2375 MHz (19 Gbps effective). The Intel GPU's bandwidth advantage of 122% suggests it handles memory-intensive workloads more efficiently despite lower compute throughput.

Architecture Differences

The Intel Arc Pro B65 uses the BMG-G21 chip built on the Xe2-HPG architecture, part of the Battlemage Pro Series generation. It is fabricated on a 5 nm process at TSMC, containing 19,600 million transistors on a 272 mm² die, yielding a transistor density of 72.1 million per square millimeter. The NVIDIA N1X 48SM uses the GB20B chip on the Blackwell 2.0 architecture, part of the Blackwell IGP (N1x) generation. It also uses a 5 nm TSMC process, but its die measures 382 mm², which is 40% larger than the Intel die. The NVIDIA part's transistor count is listed as unknown, and no density figure is recorded.

The Intel GPU features 2,560 shading units, 160 TMUs, 80 ROPs, and 20 ray tracing cores. It has no tensor cores listed. The NVIDIA GPU features 6,144 shading units, 384 TMUs, 48 ROPs, 48 ray tracing cores, and 192 tensor cores. The NVIDIA part has 2.4 times the shading units, 2.4 times the TMUs, and 2.4 times the ray tracing cores, but only 60% of the ROPs compared to Intel.

Memory configurations differ fundamentally. Intel uses 32 GB of GDDR6 on a 256-bit bus with 608.0 GB/s bandwidth. NVIDIA uses 128 GB of LPDDR5X on a 256-bit bus with 273.2 GB/s bandwidth. The Intel part's memory clock is 2375 MHz (19 Gbps effective), while the NVIDIA part runs at 1067 MHz (8.5 Gbps effective).

Power and physical characteristics show a clear split between a discrete add-in card and an integrated graphics processor. The Intel Arc Pro B65 carries a 200 W TDP, requires a single 8-pin power connector, and a suggested 550 W power supply. It occupies a dual-slot design and outputs video through 4x DisplayPort 2.1. The NVIDIA N1X 48SM is an IGP with no TDP listed, no power connectors, no suggested PSU, and a single HDMI output. Both use PCIe 5.0 x16 interfaces.

The Intel part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA part lists no supported graphics APIs in the database, marked as N/A for DirectX, OpenGL, and Vulkan. Release dates differ by two months: Intel on March 31, 2026, and NVIDIA on May 31, 2026. Both are marked as Active production status.

The Verdict

The data indicates two GPUs optimized for opposite ends of the graphics workload spectrum. The Intel Arc Pro B65 is a discrete, dual-slot card with full graphics API support, 4x DisplayPort 2.1 outputs, and a 200 W power envelope. Its strengths lie in pixel throughput at 192.0 GPixel/s and memory bandwidth at 608.0 GB/s, both of which exceed the NVIDIA part. The Intel GPU also lists a complete DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 feature set, making it suitable for conventional graphics rendering workloads that rely on rasterization and standard API calls.

The NVIDIA N1X 48SM is an integrated graphics processor with no TDP, no power connectors, and no graphics API support in the database. It delivers 28.83 TFLOPS of FP32 and FP16 compute, 192 tensor cores, 48 ray tracing cores, and 128 GB of LPDDR5X memory. Its compute density and tensor core count suggest it is designed for compute-oriented tasks rather than traditional graphics output. The lack of API support and the single HDMI output reinforce this interpretation.

Users requiring a graphics card for rendering, display output, or API-driven workloads should select the Intel Arc Pro B65 based on its pixel rate advantage, higher memory bandwidth, and complete API support. Users needing maximum FP32 throughput, tensor core acceleration, or large memory capacity for compute tasks should select the NVIDIA N1X 48SM, which offers 135% higher FP32, 192 tensor cores, and 4 times the memory capacity. The NVIDIA part's 900.9 GTexel/s texture rate also indicates superior texture processing capability. The recorded data shows no benchmark results, so these conclusions derive strictly from the architectural specifications and compute figures in the database.
