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

Head-to-Head Benchmarks

The database records no head-to-head benchmark results for the Intel Arc Pro B65 versus the NVIDIA RTX PRO 4500 Blackwell Server. Both cards show an average benchmark score of zero and a percentile ranking of 50 against all GPUs, which indicates that no standardized performance measurements have been published for either product in the current database snapshot. Without recorded frame rates, compute scores, or render times, a direct numerical comparison of application performance is not possible from the available data. What can be compared directly are the architectural specifications and theoretical throughput figures, which are fully documented.

The most significant numerical gap between the two cards appears in raw compute throughput. The RTX PRO 4500 delivers 50.70 TFLOPS of FP32 performance, while the Arc Pro B65 provides 12.29 TFLOPS. That puts the NVIDIA card roughly 4.1 times ahead in single-precision floating-point work. The gap persists in FP16 operations, where the RTX PRO 4500 again delivers 50.70 TFLOPS, while the Arc Pro B65 reaches 24.58 TFLOPS using a 2:1 ratio. The NVIDIA card leads by a factor of about 2.1 in half-precision throughput.

Memory bandwidth tells a similar story, though with a smaller margin. The RTX PRO 4500's GDDR7 memory achieves 800.3 GB/s across a 256-bit bus, while the Arc Pro B65's GDDR6 memory reaches 608.0 GB/s on the same bus width. That gives the NVIDIA card a 31.6% bandwidth advantage. Both cards carry 32 GB of memory, so capacity is identical; the difference lies entirely in the memory technology and effective clock speed.

Pixel and texture throughput also favor the RTX PRO 4500. Its pixel rate of 270.5 GPixel/s exceeds the Arc Pro B65's 192.0 GPixel/s by 40.9%. Its texture rate of 792.1 GTexel/s is more than double the Arc's 384.0 GTexel/s, a 106% advantage. These figures reflect the NVIDIA card's much larger allocation of texture mapping units and render output units.

Architecture Differences

The two cards come from different architectural lineages. The Intel Arc Pro B65 uses the BMG-G21 chip based on the Xe2-HPG architecture, part of the Battlemage Pro Series generation. The NVIDIA RTX PRO 4500 Blackwell Server uses the GB203 chip based on the Blackwell 2.0 architecture, belonging to the Server Blackwell (Bxx) generation. Both chips are manufactured on a 5 nm process at TSMC, but the physical implementations differ substantially.

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, giving a density of 72.1 million per square millimeter. The NVIDIA chip therefore has 2.3 times more transistors on a 39% larger die, with significantly higher packing density.

Shader resources diverge sharply. The RTX PRO 4500 has 10,496 shading units, 328 texture mapping units, 112 render output units, 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 cores listed in the database. The NVIDIA card provides 4.1 times more shading units, 2.05 times more TMUs, 1.4 times more ROPs, and 4.1 times more ray tracing cores. The tensor core count on the NVIDIA side, 328, has no counterpart in the Intel specification.

Clock behavior differs as well. The Arc Pro B65 runs at a fixed 2400 MHz base and boost clock, with no game clock specified. The RTX PRO 4500 has a 1215 MHz base clock and a 2415 MHz boost clock. The Intel card's sustained clock matches the NVIDIA card's boost clock almost exactly, but the NVIDIA card ramps from a lower base to a slightly higher peak. Memory clocks also differ: the Arc uses 2375 MHz (19 Gbps effective) GDDR6, while the NVIDIA card uses 1563 MHz (25 Gbps effective) GDDR7.

Power delivery and physical design diverge. The Arc Pro B65 has a 200 W TDP, requires a single 8-pin power connector, and occupies a dual-slot form factor. The RTX PRO 4500 has a 165 W TDP, uses a single 16-pin connector, and fits in a single slot. The NVIDIA card is physically smaller, with a length of 267 mm (10.5 inches), height of 111 mm (4.4 inches), and width of 40 mm (1.6 inches). No dimensions are recorded for the Intel card. The suggested power supply rating is 550 W for the Arc and 450 W for the NVIDIA card.

Display outputs present a major functional difference. The Arc Pro B65 provides four DisplayPort 2.1 outputs, making it suitable for direct display connection. The RTX PRO 4500 has no display outputs at all, indicating it is designed exclusively for server compute workloads. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Where Each One Wins

Based on the recorded specifications, the RTX PRO 4500 Blackwell Server wins in every measured compute and throughput category. Its FP32 throughput of 50.70 TFLOPS is 4.1 times the Arc Pro B65's 12.29 TFLOPS. Its FP16 throughput of 50.70 TFLOPS is 2.1 times the Arc's 24.58 TFLOPS. Its memory bandwidth of 800.3 GB/s is 31.6% higher than the Arc's 608.0 GB/s. Its pixel rate is 40.9% higher, and its texture rate is 106% higher. The NVIDIA card also carries 4.1 times more shading units and 4.1 times more ray tracing cores, plus 328 tensor cores where the Intel card has none recorded.

The Arc Pro B65 wins in categories related to clock stability and display functionality. It maintains a constant 2400 MHz clock across base and boost, whereas the NVIDIA card drops to 1215 MHz at base before boosting to 2415 MHz. The Arc card also provides four DisplayPort 2.1 outputs, which the NVIDIA server card lacks entirely. For any workload that requires driving displays directly, the Intel card is the only functional option between the two.

Power consumption favors the NVIDIA card despite its higher performance. The RTX PRO 4500 draws 165 W under load, while the Arc Pro B65 draws 200 W. The NVIDIA card achieves its large performance advantage while consuming 17.5% less power. The suggested power supply requirement also reflects this: 450 W for the NVIDIA card versus 550 W for the Intel card.

The Verdict

The recorded data shows a clear performance hierarchy. The NVIDIA RTX PRO 4500 Blackwell Server is the substantially more powerful card in every computational metric. It delivers over four times the FP32 throughput, over twice the FP16 throughput, higher memory bandwidth, faster pixel and texture processing, and vastly more shading, ray tracing, and tensor resources. It also does so with a lower TDP and a smaller physical footprint. For any server compute workload where raw throughput matters, the NVIDIA card is the stronger choice based on the numbers.

The Intel Arc Pro B65 offers a different value proposition within the data. It is the only card with display outputs, providing four DisplayPort 2.1 connections. Its constant 2400 MHz clock means no boost variance under sustained load. It carries the same 32 GB memory capacity as the NVIDIA card, though with slower GDDR6 memory. Its FP16 throughput of 24.58 TFLOPS, while half that of the NVIDIA card, still represents a substantial half-precision compute capability.

The choice between these cards depends on the intended role. For a server environment with no display requirement, where compute density and throughput are the priorities, the RTX PRO 4500 dominates every recorded metric. For a workstation or edge deployment that must drive monitors directly, the Arc Pro B65 is the only option that supports display output. The NVIDIA card also has a longer recorded product history, with a predecessor listed as Server Hopper and a successor listed as Server Rubin, while the Intel card has no predecessor or successor recorded.

The release dates are close: the NVIDIA card launched on 2026-03-16, and the Intel card on 2026-03-31. Both are listed as Active in production status. Neither card has a recorded launch MSRP in the database.
