Intel Arc Pro B65 vs NVIDIA RTX PRO 4500 Blackwell Workstation Comparison

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results for the Intel Arc Pro B65 and the NVIDIA RTX PRO 4500 Blackwell Workstation. Both cards have an average benchmark score of zero and a percentile rank of 50 among all GPUs, meaning no measured performance data is available to differentiate them through direct comparison. Consequently, the wins column shows zero for each product, and the head-to-head benchmark array is empty. Any performance assessment must therefore rely entirely on the specification sheets captured in the database, not on empirical test results. The absence of benchmark data means that claims about relative speed, rendering throughput, or compute capability cannot be substantiated with recorded measurements. What the database does provide is a full set of architectural and memory characteristics for both cards, which allows for a theoretical comparison of their capabilities.

The NVIDIA RTX PRO 4500 delivers a substantially higher FP32 compute rating at 50.53 TFLOPS versus 12.29 TFLOPS for the Intel Arc Pro B65, a 4.1x advantage. Texture fill rate favors NVIDIA as well, with 789.5 GTexel/s against 384.0 GTexel/s, roughly a 2.1x difference. Pixel throughput also leans NVIDIA, at 269.6 GPixel/s versus 192.0 GPixel/s. Memory bandwidth is another clear separation: the RTX PRO 4500 reaches 896.0 GB/s with GDDR7 memory, while the Arc Pro B65 tops out at 608.0 GB/s on GDDR6. These figures indicate that the NVIDIA card holds the raw throughput advantage across every measured compute and memory metric. The Intel card does have a higher base clock at 2400 MHz versus 1635 MHz, but the boost clocks are nearly identical, with Intel at 2400 MHz and NVIDIA at 2407 MHz.

Shading unit counts differ dramatically. The RTX PRO 4500 contains 10,496 shading units, 328 texture mapping units, 112 ROPs, 82 ray tracing cores, and 328 tensor cores. The Arc Pro B65 has 2,560 shading units, 160 TMUs, 80 ROPs, and 20 ray tracing cores, with no tensor core count recorded. This 4x disparity in shading units aligns with the FP32 throughput gap. The Intel card does feature a higher transistor density per square millimeter on its smaller die, 72.1M per mm² across 272 mm², compared to 120.6M per mm² across 378 mm² for NVIDIA, but the total transistor count tells the real story: NVIDIA integrates 45,600 million transistors versus 19,600 million on the Intel chip. That difference reflects the larger compute investment in the NVIDIA design.

Both cards share a 32 GB memory capacity and a 256-bit memory bus, so capacity and bus width are equal. The memory type diverges, with Intel using GDDR6 and NVIDIA using GDDR7, which contributes to the bandwidth gap. Both cards carry a 200 W TDP and a suggested PSU of 550 W, meaning power draw is identical despite the performance disparity. Slot width is dual-slot for both, and both use PCIe 5.0 x16 interfaces. Display outputs match at four DisplayPort connections, though Intel specifies DisplayPort 2.1 while NVIDIA lists DisplayPort 2.1b. API support is identical across DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The NVIDIA card has recorded physical dimensions: 267 mm in length, 111 mm in height, and 40 mm in width. The Intel card has no dimension data in the database. Release dates differ, with NVIDIA arriving on 2025-03-17 and Intel on 2026-03-31, an interval of roughly one year. The NVIDIA card lists a predecessor, Workstation Ada, while the Intel card has no predecessor recorded. Both production statuses are Active.

The Verdict

The data shows a decisive theoretical advantage for the NVIDIA RTX PRO 4500 Blackwell Workstation across nearly every recorded specification. The FP32 compute rating of 50.53 TFLOPS is more than four times the Intel Arc Pro B65's 12.29 TFLOPS. Memory bandwidth sits at 896.0 GB/s versus 608.0 GB/s, a 47% margin. Texture rate, pixel rate, shading units, ray tracing cores, and tensor cores all favor NVIDIA by wide margins. The only metrics where Intel leads are base clock speed, 2400 MHz versus 1635 MHz, and transistor density per unit area, 72.1M per mm² versus 120.6M per mm². Neither of those advantages translates into a throughput win. The Intel card does match NVIDIA on memory capacity at 32 GB, power draw at 200 W, and API support, but those equalities do not offset the compute gap.

For users selecting a workstation GPU strictly from database specifications, the RTX PRO 4500 is the stronger candidate for compute-heavy tasks, ray tracing workloads, and applications that exploit tensor cores. The Intel Arc Pro B65 would be the choice only in scenarios where the lower shading unit count and reduced bandwidth are acceptable, such as basic display output or light rendering duties. Since no benchmark scores exist, these conclusions rest entirely on the recorded hardware characteristics. The NVIDIA card's 82 ray tracing cores and 328 tensor cores provide dedicated acceleration paths that the Intel card lacks entirely in the tensor category. The absence of measured performance data means the verdict is provisional, but the specification sheet strongly indicates NVIDIA dominance. The Intel card's higher base clock is unlikely to compensate for a 4x deficit in shading units and a 1.5x deficit in bandwidth. The RTX PRO 4500 also benefits from GDDR7 memory technology, which delivers higher effective bandwidth per pin. Both cards require the same 550 W suggested PSU and occupy a dual-slot form factor, so system integration costs are similar. The NVIDIA card's predecessor lineage, Workstation Ada, suggests an established driver and software ecosystem, while the Intel card has no recorded predecessor in the database. Overall, the measured specifications point to the RTX PRO 4500 as the superior workstation accelerator.

Architecture Differences

The Intel Arc Pro B65 is built on the Xe2-HPG architecture, part of the Battlemage Pro Series generation, using the BMG-G21 chip. The NVIDIA RTX PRO 4500 uses Blackwell 2.0 architecture on the GB203 chip, from the Blackwell PRO W (x000) generation. Both are manufactured at TSMC on a 5 nm process, but the NVIDIA chip integrates more than twice the transistors, 45,600 million versus 19,600 million, across a larger die, 378 mm² versus 272 mm². The shading unit count is the primary architectural separator: NVIDIA packs 10,496 shading units, 328 TMUs, and 112 ROPs, while Intel provides 2,560 shading units, 160 TMUs, and 80 ROPs. Ray tracing hardware differs by a factor of four, with NVIDIA at 82 RT cores and Intel at 20. Tensor cores appear only on the NVIDIA card, with 328 units recorded, while the Intel card has no tensor core field in the database.

Where Each One Wins

The NVIDIA RTX PRO 4500 wins on every recorded compute and memory throughput metric. FP32 performance is 50.53 TFLOPS, which is 4.1x the Intel Arc Pro B65's 12.29 TFLOPS. Memory bandwidth is 896.0 GB/s versus 608.0 GB/s, a 47% lead. Texture rate is 789.5 GTexel/s versus 384.0 GTexel/s, and pixel rate is 269.6 GPixel/s versus 192.0 GPixel/s. The NVIDIA card also carries dedicated tensor cores, 328 of them, which the Intel card lacks entirely, making the RTX PRO 4500 the clear choice for workloads that leverage tensor operations. The 82 ray tracing cores on NVIDIA versus 20 on Intel give it a strong theoretical advantage for ray-traced rendering. The Intel Arc Pro B65 wins on base clock speed, 2400 MHz versus 1635 MHz, and on transistor density, 72.1M per mm² versus 120.6M per mm², though those wins do not translate into higher throughput. Intel also matches NVIDIA on memory capacity at 32 GB, power draw at 200 W, and API support. For scenarios where power consumption is a constraint, both cards are equal at 200 W TDP, so neither has an efficiency advantage in the power envelope. The Intel card is the only one of the two with a 1x 8-pin power connector, which may simplify installation in systems without 16-pin cables, but the NVIDIA card's 1x 16-pin connector is paired with the same 550 W suggested PSU. The NVIDIA card has a recorded physical footprint, 267 mm by 111 mm by 40 mm, while the Intel card's dimensions are unmeasured. For use cases such as machine learning inference, neural rendering, or high-bandwidth data processing, the RTX PRO 4500's tensor cores and higher bandwidth make it the superior option. For basic workstation display, 2D compositing, or light 3D workloads, the Intel card's specifications are adequate, but the data does not support any scenario where it outperforms the NVIDIA card in raw compute. The NVIDIA card also has a predecessor, Workstation Ada, which implies a mature product line, while the Intel card has no recorded predecessor.
