Intel Arc Pro B370 vs NVIDIA RTX PRO 4500 Blackwell Workstation Comparison

Where Each One Wins

The Intel Arc Pro B370 and NVIDIA RTX PRO 4500 Blackwell Workstation occupy fundamentally different positions in the workstation GPU landscape. The Intel part is an integrated graphics processor (IGP) built for the Panther Lake mobile platform, drawing just 25 W and sharing system memory. The NVIDIA part is a dual-slot discrete workstation card with 32 GB of dedicated GDDR7 memory, a 200 W thermal design power, and a PCIe 5.0 x16 interface.

The recorded data shows no direct head-to-head benchmark results between these two products, and neither has an average benchmark score in the database. The Intel Arc Pro B370 carries a 50th percentile ranking against all GPUs, as does the NVIDIA RTX PRO 4500. With no wins recorded for either side and no benchmark deltas available, the use-case split must be inferred from the architectural and specification data rather than from measured performance.

For integrated, low-power, portable workstation use, the Intel Arc Pro B370 is the clear fit. Its 25 W TDP, IGP slot width, and lack of power connectors mean it requires no additional cooling or power delivery beyond what a Panther Lake laptop or compact system provides. Display output is described as portable device dependent, which aligns with laptop and small-form-factor deployments where the GPU is part of the main processor package.

For dedicated, high-throughput workstation rendering, simulation, and AI inference, the NVIDIA RTX PRO 4500 is the obvious choice. Its 32 GB frame buffer, 896.0 GB/s memory bandwidth, and 50.53 TFLOPS of FP32 compute place it in an entirely different performance tier. The 10496 shading units, 328 texture mapping units, and 112 ROPs indicate a part designed for sustained, heavy compute loads. The 82 ray tracing cores and 328 tensor cores extend its reach into ray-traced visualization and tensor-accelerated workloads.

The Intel part wins on integration efficiency and platform simplicity. The NVIDIA part wins on raw compute, memory capacity, and bandwidth. There is no scenario in the data where these two overlap; they serve different segments of the workstation market.

Architecture Differences

The two GPUs come from different foundries and process nodes. Intel uses its own 3 nm process for the Panther Lake chip, while NVIDIA uses TSMC's 5 nm process for the GB203 die. The Intel architecture is Xe3-LPG, part of the Arc Graphics-WM (Panther Lake) generation. The NVIDIA architecture is Blackwell 2.0, part of the Blackwell PRO W (x000) generation.

Transistor counts differ dramatically. The NVIDIA GB203 die contains 45,600 million transistors on a 378 mm² die, yielding a transistor density of 120.6 million per square millimeter. The Intel die size and transistor count are listed as unknown in the database. The NVIDIA chip is a large, discrete GPU; the Intel chip is integrated into a mobile processor package.

The Intel Arc Pro B370 uses system shared memory, with memory type, bus width, and bandwidth all listed as system dependent. The NVIDIA RTX PRO 4500 has 32 GB of GDDR7 on a 256 bit bus, delivering 896.0 GB/s of dedicated bandwidth. This is a fundamental architectural divergence: shared memory versus dedicated VRAM.

Clock behavior also differs. The Intel part has a 300 MHz base clock and a 2400 MHz boost clock. The NVIDIA part has a 1635 MHz base clock and a 2407 MHz boost clock. Despite the similar boost clocks, the NVIDIA part's much larger shader array and dedicated memory produce far higher throughput. The Intel memory clock is system shared, while the NVIDIA memory runs at 1750 MHz with 28 Gbps effective speed.

The NVIDIA part includes 328 tensor cores; the Intel part lists no tensor core count. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA part adds a 16-pin power connector and requires a 550 W suggested power supply; the Intel part has no power connectors.

Head-to-Head Benchmarks

No head-to-head benchmark results exist in the database for these two products. The wins counters for both sides are zero, and the head-to-head benchmark array is empty. Neither GPU has an average benchmark score. Both sit at the 50th percentile against all GPUs, which indicates that the database has not yet recorded sufficient performance data to rank them against the broader GPU population.

Without measured scores, the specification sheet provides the only quantitative comparison. The NVIDIA RTX PRO 4500 delivers 50.53 TFLOPS of FP32 compute, while the Intel Arc Pro B370 delivers 6.144 TFLOPS. That places the NVIDIA part at roughly 8 times the FP32 throughput of the Intel part. The FP16 numbers tell a similar story: the NVIDIA part delivers 50.53 TFLOPS at 1:1 ratio, while the Intel part delivers 12.29 TFLOPS at 2:1 ratio.

Pixel and texture rates follow the same pattern. The NVIDIA part achieves 269.6 GPixel/s and 789.5 GTexel/s. The Intel part achieves 48.00 GPixel/s and 96.00 GTexel/s. The NVIDIA part is roughly 5.6 times faster in pixel fill and 8.2 times faster in texture fill.

Memory bandwidth is the largest gap. The NVIDIA part provides 896.0 GB/s from its 32 GB GDDR7 frame buffer. The Intel part's bandwidth is system dependent, meaning it varies with the host memory configuration. In any realistic system, shared memory bandwidth will be far below 896.0 GB/s, making the NVIDIA part's memory advantage even more pronounced.

The NVIDIA part has 10496 shading units versus 1280 on the Intel part, 328 TMUs versus 40, 112 ROPs versus 20, and 82 RT cores versus 10. Every compute resource on the NVIDIA part is substantially larger.
