Intel Arc Pro B390 vs NVIDIA RTX PRO 4500 Blackwell Workstation Comparison

Head-to-Head Benchmarks

The recorded database contains no head-to-head benchmark entries for the Intel Arc Pro B390 and the NVIDIA RTX PRO 4500 Blackwell Workstation. The winsA and winsB fields both register zero, indicating that no direct comparative tests have been logged. This absence of measured data means the performance relationship between these two workstation graphics solutions cannot be quantified through empirical scores at this time.

What the database does provide is a theoretical specification comparison that allows for a projected performance differential. The NVIDIA RTX PRO 4500 delivers 50.53 TFLOPS of FP32 compute, while the Intel Arc Pro B390 produces 7.680 TFLOPS. That represents a 6.6x raw compute advantage for the NVIDIA part, a gap that would dominate any compute-bound workload. In texture throughput, the RTX PRO 4500 reaches 789.5 GTexel/s versus 120.0 GTexel/s for the Intel, a 6.6x margin. Pixel fill rates tell a similar story: 269.6 GPixel/s for NVIDIA versus 60.00 GPixel/s for Intel, a 4.5x difference. These numbers, drawn strictly from the specification fields, suggest the NVIDIA product operates in a different performance class entirely.

The Intel part counters with a higher boost clock in one narrow sense: 2500 MHz versus 2407 MHz for NVIDIA. However, the base clock comparison flips decisively, with NVIDIA at 1635 MHz and Intel at 300 MHz. The Intel boost clock advantage does not translate into throughput advantages given the massive disparity in shading units, 10496 for NVIDIA versus 1536 for Intel, and texture mapping units, 328 versus 48. The benchmark database shows no recorded wins for either product, so the head-to-head analysis must rely on these architectural deltas rather than observed test results.

Architecture Differences

The two products originate from fundamentally different design philosophies. The Intel Arc Pro B390 uses the Panther Lake chip built on Intel's Xe3-LPG architecture, fabricated on a 3 nm process at Intel's own foundry. The NVIDIA RTX PRO 4500 Blackwell Workstation uses the GB203 chip with Blackwell 2.0 architecture, built on a 5 nm process at TSMC. The process node difference favors Intel in transistor density potential, but the NVIDIA chip packs 45,600 million transistors on a 378 mm² die, yielding a transistor density of 120.6M per mm². Intel's transistor count and die size are listed as unknown in the database, so no direct density comparison is possible.

The memory subsystem presents a stark contrast. The Intel Arc Pro B390 uses system shared memory, with its size, type, bus width, and bandwidth all dependent on the host system. The NVIDIA RTX PRO 4500 ships with 32 GB of dedicated GDDR7 memory on a 256 bit bus, delivering 896.0 GB/s of bandwidth. The NVIDIA memory clock runs at 1750 MHz with 28 Gbps effective data rate. This dedicated high-bandwidth memory configuration suits large datasets and GPU-accelerated rendering, while the Intel part relies entirely on platform memory, making its performance variable based on the host configuration.

Ray tracing and tensor capabilities further separate the two. The RTX PRO 4500 includes 82 ray tracing cores and 328 tensor cores, while the Intel Arc Pro B390 has 12 ray tracing cores and no tensor cores listed. The NVIDIA part achieves FP16 performance at a 1:1 ratio with FP32, both at 50.53 TFLOPS, whereas Intel delivers FP16 at 15.36 TFLOPS using a 2:1 ratio relative to its FP32 output. This indicates NVIDIA's compute pipeline handles FP16 workloads without a throughput penalty, while Intel trades off precision for speed. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature support matches.

Power and physical design diverge significantly. The Intel Arc Pro B390 draws 80 W and integrates as an IGP (integrated graphics processor) with no power connectors and no slot width. The NVIDIA RTX PRO 4500 consumes 200 W, occupies a dual-slot form factor, requires a single 16-pin power connector, and suggests a 550 W power supply. The NVIDIA card measures 267 mm in length, 111 mm in height, and 40 mm in width. The Intel part has no listed dimensions, consistent with its IGP nature. The bus interface confirms this split: Intel uses IGP, while NVIDIA uses PCIe 5.0 x16.

Display outputs also differ. The Intel Arc Pro B390 lists "Portable Device Dependent" outputs, meaning connectivity depends on the host laptop or portable device. The NVIDIA RTX PRO 4500 provides 4x DisplayPort 2.1b. Release dates place the NVIDIA product first at 2025-03-17, with the Intel part following on 2026-01-26. The NVIDIA predecessor is Workstation Ada, while Intel's predecessor is HD Graphics-WM. Both products remain in active production status.

The Verdict

The data indicates a clear performance hierarchy. The NVIDIA RTX PRO 4500 Blackwell Workstation operates at a 6.6x FP32 compute advantage, a 6.6x texture rate advantage, and a 4.5x pixel rate advantage over the Intel Arc Pro B390. The NVIDIA part also provides 32 GB of dedicated GDDR7 memory with 896.0 GB/s bandwidth, while Intel relies on system shared memory. For any workload that stresses GPU compute, memory bandwidth, or ray tracing, the NVIDIA product stands as the superior option based on specification data.

The Intel Arc Pro B390 does hold advantages in specific areas. Its 3 nm process node indicates a more advanced manufacturing technology, and its 80 W power draw is 120 W lower than the NVIDIA part's 200 W. The Intel boost clock of 2500 MHz exceeds the NVIDIA boost of 2407 MHz. For systems where power efficiency and integration matter more than raw throughput, the Intel IGP design offers a compelling profile. However, the database shows no benchmark scores for either product, so these conclusions derive from specification analysis rather than observed performance.

The percentile fields for both products register at 50, indicating median standing among all GPUs in the database. The average benchmark score for both is zero, reflecting the absence of logged test data. Without benchmark results, the verdict rests on architectural specifications. The NVIDIA RTX PRO 4500 clearly targets high-end workstation workloads requiring substantial compute and memory resources. The Intel Arc Pro B390 targets integrated graphics scenarios where dedicated GPU hardware is impractical or unnecessary.

Where Each One Wins

The NVIDIA RTX PRO 4500 Blackwell Workstation wins in every compute-heavy category recorded in the database. Its 50.53 TFLOPS FP32 output suits simulation, scientific computing, and large-scale rendering workflows. The 32 GB GDDR7 memory with 896.0 GB/s bandwidth handles datasets that would exhaust system shared memory configurations. The 82 ray tracing cores and 328 tensor cores accelerate ray-traced visualization and AI-assisted workloads. The PCIe 5.0 x16 interface ensures high bandwidth to the host system, and the four DisplayPort 2.1b outputs support multi-monitor professional setups. The dual-slot design with active cooling supports sustained workloads.

The Intel Arc Pro B390 wins in power efficiency and integration. Its 80 W TDP is 120 W lower than the NVIDIA part, making it suitable for compact portable devices where power budgets are constrained. The IGP design requires no additional slot space, no power connectors, and no dedicated cooling solution. The 3 nm process node indicates a manufacturing advantage that contributes to this efficiency. The higher boost clock of 2500 MHz, while paired with far fewer execution units, indicates the Intel design can reach higher per-core frequencies under boost conditions. The system shared memory model eliminates the need for separate VRAM allocation, simplifying the memory hierarchy in integrated environments.

For workstation users requiring maximum compute throughput, memory capacity, and dedicated GPU resources, the NVIDIA RTX PRO 4500 stands as the data-supported choice. For portable or power-constrained systems where GPU acceleration is secondary to integration and low power draw, the Intel Arc Pro B390 presents a viable alternative. The database records no benchmark wins for either product, so these conclusions follow from the specification differences alone.
