Analysis: Intel Arc Pro B65 vs NVIDIA RTX PRO 4500 Blackwell
Head-to-Head Benchmarks
The benchmark database records no direct head-to-head test results between the Intel Arc Pro B65 and the NVIDIA RTX PRO 4500 Blackwell. However, the RTX PRO 4500 carries a full benchmark suite while the Arc Pro B65 has no recorded scores, so the comparison relies on the RTX PRO 4500's measured performance and the architectural capabilities of the Intel card.
The RTX PRO 4500 posts an average benchmark score of 31,532 across its tested workloads. Its percentile ranking of 76 places it above 76% of all GPUs in the database. The nearest rival data shows the NVIDIA TITAN RTX at 31,676, which is 0.5% ahead of the RTX PRO 4500. The Intel Arc Pro A30M scores 31,894, sitting 1.1% higher. Two other rivals, the NVIDIA GRID M60-1Q and NVIDIA Quadro M5000, both score 31,220 and 31,206 respectively, each trailing the RTX PRO 4500 by 1%.
In individual tests, the RTX PRO 4500 delivers a 3DMark Steel Nomad DX12 score of 7,025. Its Geekbench Vulkan result reaches 221,768. The PassMark suite shows a G3D score of 33,360 and a GPU compute score of 19,255. Legacy DirectX tests produce lower numbers: DirectX 9 scores 397, DirectX 11 scores 320, DirectX 10 scores 204, and DirectX 12 scores 119. The 2D graphics test yields 1,336.
The RTX PRO 4500's FP32 compute of 50.53 TFLOPS vastly exceeds the Arc Pro B65's 12.29 TFLOPS. This 4.1x gap in raw floating-point throughput indicates the NVIDIA card handles compute-heavy workloads at a fundamentally different performance tier. The texture rate tells a similar story: 789.5 GTexel/s versus 384.0 GTexel/s, a 2.1x advantage. Pixel throughput favors NVIDIA at 269.6 GPixel/s against 192.0 GPixel/s, a 1.4x margin.

Architecture Differences
The Intel Arc Pro B65 uses the BMG-G21 chip built on Xe2-HPG architecture, part of the Battlemage Pro Series generation. It contains 19,600 million transistors on a 272 mm² die, produced on a 5 nm TSMC process. This yields a transistor density of 72.1M per mm².
The NVIDIA RTX PRO 4500 Blackwell uses the GB203 chip on Blackwell 2.0 architecture, from the Blackwell PRO W generation. It packs 45,600 million transistors on a 378 mm² die, also on a 5 nm TSMC process. Its transistor density reaches 120.6M per mm², which is 67% higher than Intel's density.
The RTX PRO 4500 deploys 10,496 shading units, 328 TMUs, and 112 ROPs. It includes 82 RT cores and 328 tensor cores. The Arc Pro B65 has 2,560 shading units, 160 TMUs, and 80 ROPs, with 20 RT cores and no tensor core count recorded.
The shading unit difference is striking: NVIDIA has 4.1 times as many shading units as Intel. TMU count favors NVIDIA by 2.05x, and ROP count favors NVIDIA by 1.4x. RT core count gives NVIDIA a 4.1x advantage at 82 versus 20. The tensor core presence on the RTX PRO 4500, absent from the Intel specification list, indicates dedicated AI acceleration hardware on the NVIDIA card.
Memory architecture differs by generation. The Arc Pro B65 uses GDDR6 memory, while the RTX PRO 4500 uses GDDR7. Both use a 256-bit bus, but the newer GDDR7 standard operates at 28 Gbps effective versus GDDR6's 19 Gbps effective. This explains the bandwidth gap: 896.0 GB/s versus 608.0 GB/s.
The Intel card's FP16 performance comes from a 2:1 ratio with FP32, meaning it halves throughput for FP16 workloads. The RTX PRO 4500 runs FP16 at a 1:1 ratio, matching its FP32 output exactly. This architectural choice makes the NVIDIA card more efficient for FP16 compute tasks.
Specification Differences
The two cards differ across nearly every specification category. Clock behavior: the Arc Pro B65 runs at a flat 2400 MHz for both base and boost. The RTX PRO 4500 has a 1635 MHz base clock that boosts to 2407 MHz.
Memory speed: Intel uses 2375 MHz (19 Gbps effective) GDDR6. NVIDIA uses 1750 MHz (28 Gbps effective) GDDR7. The effective data rate is 47% higher on NVIDIA.
Compute resources: Intel has 2,560 shading units, 160 TMUs, 80 ROPs, and 20 RT cores. NVIDIA has 10,496 shading units, 328 TMUs, 112 ROPs, and 82 RT cores. Tensor cores: NVIDIA has 328, Intel lists none.
Performance rates: Intel achieves 192.0 GPixel/s pixel rate and 384.0 GTexel/s texture rate. NVIDIA achieves 269.6 GPixel/s and 789.5 GTexel/s. FP32: Intel at 12.29 TFLOPS, NVIDIA at 50.53 TFLOPS. FP16: Intel at 24.58 TFLOPS (2:1), NVIDIA at 50.53 TFLOPS (1:1).
Physical attributes: both are dual-slot with 200 W TDP and 550 W suggested PSU. Power connectors differ: 8-pin for Intel, 16-pin for NVIDIA. Display outputs: 4x DisplayPort 2.1 for Intel, 4x DisplayPort 2.1b for NVIDIA. Dimensions recorded only for NVIDIA: 267 mm length, 111 mm height, 40 mm width.
Release timing: the Arc Pro B65 released on 2026-03-31, while the RTX PRO 4500 released on 2025-03-17, over a year earlier. The NVIDIA card's predecessor is listed as Workstation Ada. Production status for both is Active.
Where Each One Wins
The RTX PRO 4500 dominates in every measured performance category. Its FP32 compute is 4.1x higher, its texture rate is 2.1x higher, and its pixel rate is 1.4x higher. The memory bandwidth advantage of 47% benefits bandwidth-intensive workloads such as large model inference or high-resolution texture streaming. The tensor cores add dedicated AI acceleration that the Intel card lacks entirely.
The RTX PRO 4500's benchmark suite confirms its strength. The 3DMark Steel Nomad score of 7,025 and Geekbench Vulkan score of 221,768 indicate strong DirectX 12 and Vulkan rendering performance. The PassMark G3D score of 33,360 and compute score of 19,255 show balanced capability across graphics and general compute.
The Arc Pro B65 wins only in specific structural categories. Its base clock of 2400 MHz exceeds NVIDIA's 1635 MHz base clock, meaning it maintains full speed without relying on boost behavior. This could benefit sustained workloads where boost clocks vary. The Intel card also uses a simpler 8-pin power connector, which may be easier to accommodate in existing systems compared to the 16-pin connector.
The RTX PRO 4500's release date of March 2025 predates the Arc Pro B65's March 2026 release by one year. The database shows the RTX PRO 4500's percentile at 76 versus the Arc Pro B65's 50, indicating the NVIDIA card sits well above the median GPU while Intel sits exactly at it. The RTX PRO 4500's average benchmark score of 31,532 stands against the Arc Pro B65's recorded 0, since no benchmarks exist for the Intel card.
The Verdict
The data clearly favors the NVIDIA RTX PRO 4500 Blackwell for any performance-sensitive workload. The 4.1x FP32 advantage, 2.1x texture rate lead, and 47% bandwidth surplus make it the stronger choice for compute, rendering, and AI tasks. The tensor cores provide hardware acceleration that the Arc Pro B65 cannot match through any recorded specification. The RTX PRO 4500's benchmark results confirm its capability: a 76th percentile ranking with an average score of 31,532 across the tested suite.
The Intel Arc Pro B65 does have a place for specific use cases. Its fixed 2400 MHz clock across base and boost simplifies power behavior. The 8-pin power connector offers broader compatibility with existing power supplies. The dual-slot design matches NVIDIA's physical footprint, and the card supports the same modern API set including DirectX 12 Ultimate and Vulkan 1.4. For systems where the 200 W TDP and 550 W PSU requirement fit existing infrastructure, the Intel card provides a viable alternative.
The RTX PRO 4500's nearest rival data shows it performs within 1.1% of the NVIDIA TITAN RTX and Intel Arc Pro A30M, with the 4500 slightly behind both. This places it in a competitive tier where small margins separate top performers. The Arc Pro B65 has no such comparison data available.
The practical choice depends on workload requirements. The RTX PRO 4500 delivers over four times the FP32 compute and includes dedicated tensor cores, making it the appropriate selection for AI inference, scientific computing, or heavy 3D rendering. The Arc Pro B65 offers 32 GB of VRAM and modern API support at a lower compute ceiling, suitable for lighter professional workloads where the full NVIDIA feature set is unnecessary. The 47% bandwidth advantage of the RTX PRO 4500 further tilts the balance toward NVIDIA for memory-intensive tasks. The recorded data provides no performance metrics for the Intel card, so any decision favoring it must rely on its architectural specifications alone.
