Intel Arc Pro B370 vs NVIDIA GeForce RTX 4090 Mobile Comparison

Intel Arc Pro B370 and NVIDIA GeForce RTX 4090 Mobile occupy opposite ends of the mobile graphics spectrum. The Arc Pro B370 is a 25 W integrated processor built on Intel’s 3 nm Panther Lake platform, while the RTX 4090 Mobile is a 120 W discrete part using the AD103 chip on TSMC’s 5 nm process. The recorded data shows an 84th percentile ranking for the RTX 4090 Mobile against all GPUs, versus the 50th percentile for the Arc Pro B370. The RTX 4090 Mobile carries an average benchmark score of 43667, while the Arc Pro B370 has no recorded benchmark scores in the database, making direct numerical comparison impossible. The analysis below relies on the architectural and performance data available for the RTX 4090 Mobile and the specifications of the Arc Pro B370.

Where Each One Wins

The RTX 4090 Mobile wins in every measurable performance category. Its Geekbench OpenCL score of 180831 and Vulkan score of 170774 represent substantial compute throughput. Passmark results reinforce this dominance: a G3D score of 27212, a GPU compute score of 12347, DirectX 11 at 262, DirectX 9 at 310, DirectX 10 at 173, DirectX 12 at 107, and G2D at 984. These figures place it far ahead of the Arc Pro B370, which has no recorded benchmark data. The RTX 4090 Mobile also wins on raw throughput specifications, with 32.98 TFLOPS FP32 performance versus 6.144 TFLOPS for the Arc Pro B370, a difference of roughly 5.37 times. Texture rate favors NVIDIA at 515.3 GTexel/s against 96.00 GTexel/s, and pixel rate favors NVIDIA at 189.8 GPixel/s against 48.00 GPixel/s.

The Arc Pro B370 wins in power efficiency and integration. Its 25 W TDP is one-fifth of the RTX 4090 Mobile’s 120 W TDP. It requires no power connectors and uses system shared memory, which suits compact portable devices. Its base clock of 300 MHz and boost clock of 2400 MHz show a wide dynamic range, allowing the chip to scale down aggressively when idle. The RTX 4090 Mobile uses a higher base clock of 1335 MHz and a boost of 1695 MHz, which consumes more power at all times. For thermally constrained systems, the Arc Pro B370 presents the only viable option among the two, as its integrated design eliminates the need for discrete memory and power delivery.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. Intel builds the Arc Pro B370 on its Xe3-LPG architecture, part of the Arc Graphics-WM (Panther Lake) generation. It uses Intel’s 3 nm process node and is produced in-house by Intel. The chip integrates 1280 shading units, 40 TMUs, 20 ROPs, and 10 RT cores. It has no dedicated tensor cores. Memory is system shared, with no dedicated VRAM, bus width, or bandwidth figures; bandwidth is listed as system dependent. The GPU relies on the host system’s memory controller, which introduces latency and bandwidth limitations compared to discrete memory.

NVIDIA’s RTX 4090 Mobile uses the Ada Lovelace architecture with the AD103 chip, built on TSMC’s 5 nm process. The die measures 379 mm² and contains 45,900 million transistors, yielding a transistor density of 121.1M per mm². The chip includes 9728 shading units, 304 TMUs, 112 ROPs, 76 RT cores, and 304 tensor cores. It uses 16 GB of GDDR6 memory on a 256-bit bus, delivering 576.0 GB/s of bandwidth. The memory clock runs at 2250 MHz with 18 Gbps effective data rate. The RTX 4090 Mobile connects via PCIe 4.0 x16, while the Arc Pro B370 uses an integrated graphics processor interface with no bus interface beyond IGP.

The transistor counts differ enormously. The RTX 4090 Mobile packs 45,900 million transistors, while the Arc Pro B370’s transistor count is unknown in the database. Die size for the Arc Pro B370 is also unknown, preventing density comparisons. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature parity exists despite the hardware gap. The RTX 4090 Mobile has dedicated tensor cores and RT cores, enabling hardware acceleration for AI workloads and ray tracing, whereas the Arc Pro B370 has RT cores but no tensor cores. The RTX 4090 Mobile’s FP16 performance matches its FP32 at 32.98 TFLOPS (1:1), while the Arc Pro B370 achieves 12.29 TFLOPS FP16 via a 2:1 ratio, indicating a more limited FP16 path.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the Arc Pro B370 and the RTX 4090 Mobile. The Arc Pro B370 has zero recorded benchmark results and zero wins in the winsA field, while the RTX 4090 Mobile has nine recorded benchmark results and zero wins in the winsB field, reflecting the absence of direct comparison data. The RTX 4090 Mobile’s nearest rivals provide context for its performance tier. It sits 0.8% above the NVIDIA Quadro M6000 (43301 average score), 0.9% above the GeForce RTX 5050 Mobile (43268), and 0.9% above the Quadro M6000 24 GB (43262). It trails the RTX A6000 by 0.9%, which posts an average score of 44075. These margins show the RTX 4090 Mobile clustering tightly with professional and high-end consumer GPUs, all within roughly one percent of each other.

The RTX 4090 Mobile’s individual benchmark scores illustrate its strength. Geekbench OpenCL at 180831 leads its Vulkan score of 170774 by about 5.9%, showing strong compute performance across both APIs. Passmark G3D at 27212 confirms gaming-class rasterization capability. The DirectX 11 score of 262 exceeds the DirectX 12 score of 107 by a wide margin, indicating that legacy API workloads run more efficiently in this configuration. DirectX 9 at 310 and DirectX 10 at 173 follow a similar pattern, with older APIs performing relatively well. The G2D score of 984 and GPU compute score of 12347 round out the profile. The average benchmark score of 43667 places it in the top quartile of all GPUs, with an 84th percentile ranking.

Against the Arc Pro B370, the RTX 4090 Mobile’s specifications dominate. The RTX 4090 Mobile has 7.6 times more shading units (9728 versus 1280), 7.6 times more TMUs (304 versus 40), and 5.6 times more ROPs (112 versus 20). It has 7.6 times more RT cores (76 versus 10) and 304 tensor cores against none. Memory bandwidth of 576.0 GB/s versus system dependent bandwidth creates a fundamental throughput gap. The RTX 4090 Mobile’s 16 GB GDDR6 memory provides dedicated capacity, while the Arc Pro B370 uses shared system memory with no fixed size. The RTX 4090 Mobile’s pixel rate of 189.8 GPixel/s is 3.95 times the Arc Pro B370’s 48.00 GPixel/s, and its texture rate of 515.3 GTexel/s is 5.37 times the Arc Pro B370’s 96.00 GTexel/s.

The Verdict

The recorded data directs a clear split. The RTX 4090 Mobile is the choice for any workload requiring maximum compute, gaming, or professional rendering. Its 32.98 TFLOPS FP32, 576.0 GB/s memory bandwidth, and 9728 shading units place it in a performance class that the Arc Pro B370 cannot approach. Its 84th percentile ranking and average benchmark score of 43667 confirm its position among the fastest mobile GPUs. The nearest rival data shows it trading blows with the RTX A6000, Quadro M6000, and RTX 5050 Mobile, all within one percent, which places it in a tightly contested high-end tier. Users who need ray tracing, AI acceleration via tensor cores, or high-resolution texture workloads should select the RTX 4090 Mobile.

The Arc Pro B370 serves a different purpose. Its 25 W TDP, integrated design, and system shared memory make it suitable for thin and light portable devices where power draw and thermal output are the primary constraints. Its 1280 shading units and 6.144 TFLOPS FP32 provide basic graphics capability, and its 3 nm process node from Intel indicates a modern manufacturing approach. The lack of benchmark data means no performance validation exists in the database, so its real-world speed remains unquantified. The RTX 4090 Mobile wins every measurable performance metric, while the Arc Pro B370 wins the efficiency and integration categories. The data does not support choosing the Arc Pro B370 for performance-driven tasks; it only supports scenarios where the 120 W power envelope of the RTX 4090 Mobile is unacceptable.
