Intel Arc Pro B65 vs NVIDIA RTX 4500 Ada Generation Comparison

Where Each One Wins

The Intel Arc Pro B65 and NVIDIA RTX 4500 Ada Generation occupy different performance tiers, and the benchmark data reflects a clear split. The RTX 4500 Ada Generation sits at the 97th percentile of all GPUs in the database, while the Intel Arc Pro B65 is at the 50th percentile. This is not a close contest in raw compute; the NVIDIA card dominates in every measured category where both have recorded data.

The RTX 4500 Ada Generation has a recorded average benchmark score of 166,094, with specific Geekbench scores of 160,786 in OpenCL and 171,401 in Vulkan. The Intel Arc Pro B65 has no recorded benchmark scores in the database, meaning the head-to-head comparison is one-sided in terms of measurable performance. The NVIDIA card wins all benchmark categories by default, as the Intel card has no entries to compare against.

For workloads that rely on FP32 compute, the RTX 4500 Ada Generation delivers 39.63 TFLOPS, a figure over three times the 12.29 TFLOPS of the Intel Arc Pro B65. Texture throughput follows a similar pattern: 619.2 GTexel/s versus 384.0 GTexel/s. Pixel rate is closer, with the NVIDIA card at 206.4 GPixel/s versus 192.0 GPixel/s for Intel, but the NVIDIA card still leads.

The Intel Arc Pro B65 wins in memory capacity, offering 32 GB GDDR6 versus 24 GB on the NVIDIA card. It also has a wider 256-bit memory bus versus 192-bit, and higher memory bandwidth at 608.0 GB/s versus 432.0 GB/s. For large datasets or models that exceed 24 GB, the Intel card has an advantage that the raw compute scores do not capture.

Architecture Differences

The two cards use different architectures from different vendors. The Intel Arc Pro B65 uses Xe2-HPG architecture on the BMG-G21 chip, part of the Battlemage (Pro Series) generation. The NVIDIA RTX 4500 Ada Generation uses Ada Lovelace architecture on the AD103 chip, part of the Workstation Ada generation. Both are fabricated on a 5 nm process at TSMC, but the similarity ends there.

The NVIDIA chip is substantially larger: 45,900 million transistors on a 379 mm² die, compared to 19,600 million transistors on a 272 mm² die for Intel. Transistor density is 121.1M per mm² for NVIDIA versus 72.1M per mm² for Intel. The NVIDIA card has 7,680 shading units, 240 TMUs, and 80 ROPs, while the Intel card has 2,560 shading units, 160 TMUs, and 80 ROPs. The NVIDIA card also has 60 RT cores and 240 tensor cores; the Intel card has 20 RT cores and no tensor cores listed.

Memory architectures differ significantly. The Intel card uses 32 GB of GDDR6 on a 256-bit bus, achieving 608.0 GB/s bandwidth. The NVIDIA card uses 24 GB of GDDR6 on a 192-bit bus, achieving 432.0 GB/s. Clock behavior differs too: Intel runs at a fixed 2400 MHz for both base and boost, while NVIDIA has a 2070 MHz base and 2580 MHz boost. The NVIDIA card supports FP16 at 1:1 ratio (39.63 TFLOPS), while Intel uses 2:1 ratio (24.58 TFLOPS FP16 versus 12.29 FP32).

Interface and output differences are notable. The Intel card uses PCIe 5.0 x16 and 4x DisplayPort 2.1 outputs. The NVIDIA card uses PCIe 4.0 x16 and 4x DisplayPort 1.4a outputs. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Power draw is similar: 200 W for Intel, 210 W for NVIDIA, both dual-slot with a suggested 550 W PSU. The NVIDIA card has no power connectors listed, while Intel uses a single 8-pin.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two cards. However, the RTX 4500 Ada Generation has its own recorded scores, and rival comparisons provide context. The NVIDIA card scores 160,786 in Geekbench OpenCL and 171,401 in Geekbench Vulkan, with an average of 166,094 across both.

Comparing the RTX 4500 Ada Generation to its nearest rivals in the database shows where it stands. It is 0.5% ahead of the NVIDIA RTX A5500 (average score 165,217), 0.7% ahead of the AMD Radeon PRO W7800 (164,894), and 2.2% ahead of the NVIDIA A100 PCIe 40 GB (162,504). It is 1.5% behind the AMD Radeon Pro W6900X (168,574). These are narrow margins, indicating the RTX 4500 Ada Generation is tightly grouped with high-end workstation cards from the previous generation.

The Intel Arc Pro B65 has no benchmark scores in the database, so its performance relative to the RTX 4500 cannot be quantified from recorded data. What can be stated is that the Intel card has a 50th percentile ranking versus the NVIDIA card's 97th percentile, which places them in entirely different performance brackets. The NVIDIA card's FP32 throughput of 39.63 TFLOPS is more than triple the Intel card's 12.29 TFLOPS, and its texture rate of 619.2 GTexel/s is 61% higher than Intel's 384.0 GTexel/s. Pixel rate is nearly equal: 206.4 versus 192.0 GPixel/s.

The memory bandwidth advantage favors Intel: 608.0 GB/s versus 432.0 GB/s, a 40.7% difference. This is the one metric where the Intel card clearly outperforms the NVIDIA card, and it is directly tied to the larger 32 GB frame buffer. For workloads that are memory-bound rather than compute-bound, the Intel card could hold an edge, but the absence of benchmark scores means this remains theoretical.

The Verdict

The data indicates a clear separation in performance class. The NVIDIA RTX 4500 Ada Generation is a high-end workstation card at the 97th percentile, with recorded benchmark scores averaging 166,094. The Intel Arc Pro B65 sits at the 50th percentile with no recorded benchmarks, which makes direct comparison impossible but strongly suggests it is not in the same compute tier.

For compute-heavy workloads such as rendering, simulation, or AI inference (where tensor cores matter), the NVIDIA card is the obvious choice based on the recorded data. Its FP32 performance, texture rate, and RT core count (60 versus 20) all point to significantly higher throughput. The 240 tensor cores on the NVIDIA card provide a capability the Intel card lacks entirely.

The Intel Arc Pro B65 has one clear advantage: memory. With 32 GB versus 24 GB, and higher bandwidth (608.0 GB/s versus 432.0 GB/s), it is better suited for large datasets that exceed the NVIDIA card's frame buffer. For workloads where memory capacity is the bottleneck, the Intel card's larger pool could matter more than raw compute.

The release dates are relevant for context. The NVIDIA RTX 4500 Ada Generation launched in August 2023, while the Intel Arc Pro B65 is dated March 2026. The NVIDIA card has a predecessor (Workstation Ampere) and successor (Blackwell PRO W) listed, while the Intel card has no predecessor or successor in the database.

The specification differences are summarized as follows: Intel has 32 GB memory, NVIDIA has 24 GB. Intel uses PCIe 5.0, NVIDIA uses PCIe 4.0. Intel has 2,560 shading units, NVIDIA has 7,680. Intel has 20 RT cores, NVIDIA has 60. Intel has no tensor cores, NVIDIA has 240. Intel has a 2400 MHz fixed clock, NVIDIA boosts to 2580 MHz. Both use 5 nm TSMC process, both are dual-slot, both require a 550 W PSU. Intel uses DisplayPort 2.1, NVIDIA uses DisplayPort 1.4a. Intel has a 272 mm² die, NVIDIA has 379 mm².

The choice comes down to workload. If the task requires raw compute, ray tracing, or AI acceleration, the RTX 4500 Ada Generation is the only card with recorded performance data to justify it. If the task involves very large memory footprints and the compute requirements are modest, the Intel Arc Pro B65 offers more memory capacity and bandwidth at a lower transistor count. The database contains no benchmark results for the Intel card, so any performance claims for it must be inferred from specifications alone.
