Analysis: Intel Arc Pro B65 vs NVIDIA RTX PRO 4000 Blackwell
Head-to-Head Benchmarks
The recorded data contains no direct head-to-head benchmark results between the Intel Arc Pro B65 and the NVIDIA RTX PRO 4000 Blackwell. However, the database provides a comprehensive benchmark suite for the NVIDIA card, allowing for meaningful interpretation of its performance class. The Intel Arc Pro B65 has no benchmark scores recorded in the database, which limits direct numerical comparison.
The NVIDIA RTX PRO 4000 Blackwell delivers an average benchmark score of 27,135 across all recorded tests. Its percentile ranking of 72 places it above the majority of all GPUs in the database. The 3DMark Steel Nomad DX12 test yields a score of 4,648, which serves as a strong indicator of modern DirectX 12 gaming and workstation performance. In Geekbench Vulkan, the card scores 194,168, demonstrating robust compute throughput in cross-platform graphics APIs.
The PassMark suite shows varied results across different DirectX versions. The DirectX 9 score of 354 and DirectX 10 score of 173 indicate strong legacy API performance, while the DirectX 11 score of 276 and DirectX 12 score of 97 show scaling across newer rendering paths. The PassMark G3D score of 28,427 and GPU compute score of 14,805 further confirm the card's balanced capabilities in both graphics and compute workloads.
Comparing the NVIDIA card to its nearest rivals in the database reveals tight competition. The AMD Radeon RX 6700 XT averages 27,425, which is 1.1% higher than the RTX PRO 4000 Blackwell. The NVIDIA GeForce RTX 4070 Mobile also averages 27,435, another 1.1% advantage. The NVIDIA GeForce RTX 3090 averages 27,565, representing a 1.6% lead over the PRO 4000. Conversely, the NVIDIA RTX A4000 averages 26,683, which is 1.7% lower, placing the PRO 4000 ahead of that workstation card.
These delta values indicate that the RTX PRO 4000 Blackwell sits in a highly competitive performance band, within roughly 2% of all four nearest rivals. The narrow margins suggest that real-world application differences would likely be more significant than raw benchmark deltas. The card's 72nd percentile ranking confirms its position as a solid mid-to-upper tier performer, though not at the extreme top of the database.

The Verdict
The data clearly favors the NVIDIA RTX PRO 4000 Blackwell for raw compute and rendering throughput. Its FP32 rating of 36.83 TFLOPS is three times the Intel Arc Pro B65's 12.29 TFLOPS. The NVIDIA card also leads in texture rate at 575.4 GTexel/s versus 384.0 GTexel/s, and pixel rate at 197.3 GPixel/s versus 192.0 GPixel/s. The shading unit count of 8,960 versus 2,560 and RT core count of 70 versus 20 further reinforce this advantage.
Memory bandwidth tells a different story. The Intel card's 608.0 GB/s is lower than the NVIDIA card's 672.0 GB/s, but the Intel card offers 32 GB of memory versus 24 GB. The larger capacity may benefit workloads with very large datasets that exceed the NVIDIA card's VRAM allocation.
Power efficiency favors the NVIDIA card. It achieves higher performance with a 140 W TDP and 300 W suggested PSU, while the Intel card requires 200 W and a 550 W suggested PSU. The NVIDIA card is also single-slot, while the Intel card is dual-slot.
The NVIDIA card's 72nd percentile ranking versus the Intel card's 50th percentile indicates a substantially higher position in the overall database distribution. For users requiring maximum compute throughput, the NVIDIA RTX PRO 4000 Blackwell is the clear choice. The Intel Arc Pro B65 may be preferable only when the 32 GB memory capacity is essential and the lower compute performance is acceptable.
Specification Differences
The two cards differ across nearly every specification field. The Intel Arc Pro B65 uses a BMG-G21 chip, while the NVIDIA RTX PRO 4000 Blackwell uses GB203. The Intel card has a base and boost clock of 2400 MHz, while the NVIDIA card has a base clock of 1230 MHz and a boost clock of 2055 MHz. Memory clocks differ as well: 2375 MHz with 19 Gbps effective for Intel, 1750 MHz with 28 Gbps effective for NVIDIA.
Memory capacity is 32 GB GDDR6 for Intel versus 24 GB GDDR7 for NVIDIA. Bus width is 256-bit versus 192-bit. Bandwidth is 608.0 GB/s versus 672.0 GB/s. Shading units are 2,560 versus 8,960. TMUs are 160 versus 280. ROPs are 80 versus 96. RT cores are 20 versus 70. The NVIDIA card has 280 tensor cores; the Intel card has none recorded.
Pixel rate is 192.0 GPixel/s versus 197.3 GPixel/s. Texture rate is 384.0 GTexel/s versus 575.4 GTexel/s. FP32 is 12.29 TFLOPS versus 36.83 TFLOPS. FP16 is 24.58 TFLOPS versus 36.83 TFLOPS. TDP is 200 W versus 140 W. Slot width is dual-slot versus single-slot. Power connectors are 1x 8-pin versus 1x 16-pin. Suggested PSU is 550 W versus 300 W.
Display outputs are 4x DisplayPort 2.1 versus 4x DisplayPort 2.1b. The NVIDIA card has recorded dimensions of 241 mm length, 111 mm height, and 20 mm width, while the Intel card has no dimensions recorded. The Intel card was released on 2026-03-31, and the NVIDIA card on 2025-03-17. The NVIDIA card lists "Workstation Ada" as its predecessor; the Intel card has no predecessor recorded.
Architecture Differences
The Intel Arc Pro B65 uses the Xe2-HPG architecture from the Battlemage Pro Series generation. The NVIDIA RTX PRO 4000 Blackwell uses the Blackwell 2.0 architecture from the Blackwell PRO W (x000) generation. Both are fabricated by TSMC on a 5 nm process, but the transistor counts differ substantially.
The Intel BMG-G21 chip contains 19,600 million transistors on a 272 mm² die, resulting in a transistor density of 72.1 million per mm². The NVIDIA GB203 chip contains 45,600 million transistors on a 378 mm² die, resulting in a transistor density of 120.6 million per mm². The NVIDIA chip has a 2.3x transistor advantage and a 1.7x density advantage.
The NVIDIA architecture includes dedicated tensor cores, with 280 of them, which the Intel architecture lacks entirely. This gives the NVIDIA card a significant advantage in AI-accelerated workloads. The RT core counts also differ: 70 for NVIDIA versus 20 for Intel, suggesting the NVIDIA card is better equipped for ray-traced rendering.
FP16 throughput reveals a fundamental architectural difference. The Intel card delivers 24.58 TFLOPS at a 2:1 ratio relative to FP32, indicating it uses packed FP16 operations. The NVIDIA card delivers 36.83 TFLOPS at a 1:1 ratio, meaning it processes FP16 and FP32 at the same rate, which is atypical and suggests the architecture prioritizes consistent throughput across precisions.
Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and both use PCIe 5.0 x16 interfaces. The display output versions differ slightly, with Intel using DisplayPort 2.1 and NVIDIA using DisplayPort 2.1b. The NVIDIA card's single-slot design and lower power draw indicate a more efficient architecture, while the Intel card's dual-slot design with higher wattage suggests a less power-optimized implementation.
