Intel Arc Pro B65 vs NVIDIA RTX PRO 4000 Blackwell SFF Comparison

Head-to-Head Benchmarks

The database contains only one recorded benchmark result for the NVIDIA RTX PRO 4000 Blackwell SFF: a 3DMark Steel Nomad DX12 score of 2910. The Intel Arc Pro B65 has no recorded benchmark scores in the database, and there are no head-to-head benchmark entries comparing the two cards directly. Consequently, a direct numerical comparison of application performance cannot be established from recorded data.

What the data does show is where the RTX PRO 4000 Blackwell SFF sits relative to other NVIDIA cards in the same benchmark. Its score of 2910 places it within a very narrow band of comparable GPUs. The closest rival, the NVIDIA GeForce RTX 4060 Ti 16 GB, scores 2907, a delta of just 0.1 percent. The RTX PRO 4000 Blackwell SFF is effectively tied with that card. Against the GeForce RTX 4060 Ti 8 GB, which scores 2913, the RTX PRO 4000 Blackwell SFF trails by 0.1 percent. The NVIDIA Quadro P600 scores 2923, putting it 0.4 percent ahead, while the GeForce RTX 4010 scores 2893, which is 0.6 percent behind the RTX PRO 4000 Blackwell SFF.

These deltas are all within a single percentage point, which indicates that the RTX PRO 4000 Blackwell SFF delivers performance roughly equivalent to a mid-range GeForce RTX 40-series card in this specific DX12 workload. The percentile ranking of 19 percent against all GPUs in the database places it in the lower fifth of recorded graphics cards, which is consistent with a workstation-oriented card that prioritizes stability and feature support over raw rasterization throughput.

Because the Intel Arc Pro B65 has no benchmark entries, the database cannot confirm whether its 12.29 TFLOPS of FP32 compute translates into competitive real-world results. The raw specification suggests it should be substantially slower in raw shader throughput, but no measured data exists to verify that expectation. The recorded data simply does not include any performance results for the Intel card, so any head-to-head comparison must rely on architectural and specification differences rather than benchmark scores.

Architecture Differences

The two cards use fundamentally different chip designs. The Intel Arc Pro B65 is built on the Xe2-HPG architecture, specifically the BMG-G21 chip from the Battlemage Pro Series generation. The NVIDIA RTX PRO 4000 Blackwell SFF uses the Blackwell 2.0 architecture with the GB203 chip from the Blackwell PRO W (x000) generation. Both are manufactured by TSMC on a 5 nm process node, which is where the similarity ends.

The transistor counts differ sharply. The NVIDIA chip packs 45,600 million transistors on a 378 mm² die, yielding a transistor density of 120.6 million per square millimeter. The Intel chip contains 19,600 million transistors on a 272 mm² die, for a density of 72.1 million per square millimeter. The NVIDIA chip is roughly 39 percent larger in die area but carries more than twice the transistor count, indicating a dramatically more complex design.

The compute resources reflect this gap. The NVIDIA card has 8960 shading units, 280 texture mapping units, and 96 raster output pipelines. The Intel card has 2560 shading units, 160 TMUs, and 80 ROPs. The NVIDIA card also includes 70 ray tracing cores and 280 tensor cores, while the Intel card lists 20 ray tracing cores and no tensor core count in the recorded data. In FP32 compute, the NVIDIA card delivers 24.05 TFLOPS, nearly double the Intel card's 12.29 TFLOPS. The FP16 figures are also telling: the Intel card achieves 24.58 TFLOPS using a 2:1 ratio, while the NVIDIA card delivers 24.05 TFLOPS at a 1:1 ratio, meaning the NVIDIA card does not rely on rate-reducing conversion for FP16 work.

The memory subsystems diverge as well. The Intel card uses 32 GB of GDDR6 memory on a 256-bit bus, achieving 608.0 GB/s of bandwidth. The NVIDIA card uses 24 GB of GDDR7 memory on a 192-bit bus, achieving 432.0 GB/s. Despite having less memory and a narrower bus, the GDDR7 memory operates at a lower clock speed of 1125 MHz with 18 Gbps effective transfer, compared to the Intel card's 2375 MHz memory clock with 19 Gbps effective. The Intel card's wider bus gives it a 40.7 percent bandwidth advantage, which could matter in memory-heavy workstation workloads.

Clock speeds present another contrast. The Intel card runs at a flat 2400 MHz for both base and boost, with no variation. The NVIDIA card has a base clock of 405 MHz and a boost clock of 1342 MHz, a much wider dynamic range that allows for aggressive power management. The NVIDIA card's pixel rate is 128.8 GPixel/s and its texture rate is 375.8 GTexel/s, while the Intel card achieves 192.0 GPixel/s and 384.0 GTexel/s. The Intel card leads in pixel fill rate by a significant margin, despite having fewer ROPs, because of its substantially higher clock speed. The texture rates are nearly identical, with the Intel card ahead by just 2.2 percent.

Power characteristics could not be more different. The Intel card has a TDP of 200 W and requires a single 8-pin power connector, with a suggested power supply of 550 W. The NVIDIA card has a TDP of just 70 W, requires no external power connector, and has a suggested power supply of 250 W. This is a 130 W difference in thermal design power, and the NVIDIA card draws less than half the power of a typical mid-range consumer GPU while still delivering 24.05 TFLOPS.

The bus interfaces also differ. The Intel card uses PCIe 5.0 x16, while the NVIDIA card uses PCIe 5.0 x8. The NVIDIA card's reduced lane count is compensated by its much lower power draw and smaller physical footprint. The NVIDIA card measures 167 mm in length, 69 mm in height, and 40 mm in width, while the Intel card has no recorded dimensions. Both are dual-slot cards.

Display outputs are similar in count but differ in connector type. The Intel card provides four DisplayPort 2.1 outputs, while the NVIDIA card provides four mini-DisplayPort 2.1b outputs. The API support is identical: both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

From the recorded data, the NVIDIA RTX PRO 4000 Blackwell SFF is the stronger compute card. Its FP32 throughput of 24.05 TFLOPS is 95.7 percent higher than the Intel Arc Pro B65's 12.29 TFLOPS. It has more than three times the shading units, 3.5 times the ray tracing cores, and a full tensor core implementation. Its transistor budget of 45,600 million versus 19,600 million indicates a far more sophisticated design.

The Intel Arc Pro B65 counters with advantages in memory capacity and bandwidth. It offers 32 GB versus 24 GB, a 33.3 percent capacity advantage, and its 608.0 GB/s bandwidth is 40.7 percent higher than the NVIDIA card's 432.0 GB/s. The pixel fill rate also favors Intel, at 192.0 GPixel/s versus 128.8 GPixel/s, a 49.1 percent lead. These attributes suggest the Intel card may perform better in workloads that saturate memory bandwidth or require high fill rates, such as certain rendering passes or large dataset manipulations.

Power efficiency clearly favors NVIDIA. The RTX PRO 4000 Blackwell SFF delivers 24.05 TFLOPS within a 70 W TDP, while the Intel card delivers 12.29 TFLOPS within a 200 W TDP. Per watt, the NVIDIA card achieves roughly 344 GFLOPS per watt versus 61 GFLOPS per watt for Intel. The NVIDIA card also requires no external power connector and a 250 W power supply, versus a 550 W recommendation for Intel.

The release dates place the NVIDIA card as the earlier product, released on 2025-08-10, while the Intel card arrived on 2026-03-31. Both are listed as active production status.

For users whose workloads depend on raw compute throughput, ray tracing, or tensor operations, the recorded data points to the NVIDIA card. For users who need maximum memory capacity or memory bandwidth within a fixed budget, the Intel card offers measurable advantages. The NVIDIA card's 70 W power envelope makes it suitable for compact systems, while the Intel card's 200 W requirement and 8-pin connector demand a more robust power delivery system. The absence of benchmark data for the Intel card means the database cannot confirm how its architectural advantages translate into real-world performance, so any choice between these two cards based on the recorded data must weigh the confirmed compute superiority of the NVIDIA card against the confirmed memory and fill rate advantages of the Intel card.
