Intel Arc Pro B390 vs NVIDIA RTX 3500 Mobile Ada Generation 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 3500 Mobile Ada Generation. With zero benchmark results logged for either part, the winsA and winsB counters remain at zero, indicating no direct performance comparisons have been captured. The absence of measured data means no quantitative performance verdict can be derived from the database at this time. Both products hold an identical percentileVsAllGpus score of 50, placing them at the median of all tracked graphics solutions despite the lack of direct testing. The avgBenchmarkScore for both entries is zero, confirming that neither part has accumulated any validated performance samples. This neutral positioning in the percentile ranking reflects the database's current state rather than any intrinsic performance equivalence. Until head-to-head measurements are recorded, any claims about relative speed would be speculative and outside the scope of the available facts.

Architecture Differences

The Intel Arc Pro B390 is built on the Panther Lake chip using the Xe3-LPG architecture, representing the Arc Graphics-WM (Panther Lake) generation. Its process node is 3 nm, fabricated by Intel. The NVIDIA RTX 3500 Mobile Ada Generation uses the AD104 chip with Ada Lovelace architecture, belonging to the Ada-MW generation, and is manufactured on a 5 nm process by TSMC. The transistor counts differ substantially: the Intel part lists transistors as unknown, while the NVIDIA chip contains 35,800 million transistors on a 294 mm² die, yielding a transistor density of 121.8M per mm². The Intel die size is also unknown.

Clock behavior separates the two designs. The Intel Arc Pro B390 runs at a base clock of 300 MHz with a boost clock of 2500 MHz. The NVIDIA RTX 3500 Mobile Ada Generation operates at a base of 1110 MHz and a boost of 1545 MHz, with memory clocked at 2250 MHz or 18 Gbps effective. Memory configurations are fundamentally different. The Intel part uses system shared memory, with size, bus width, and bandwidth all designated as system dependent, meaning its memory subsystem relies entirely on the host platform. The NVIDIA part has 12 GB of dedicated GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of bandwidth.

Compute resources show a clear divergence. The Intel Arc Pro B390 features 1536 shading units, 48 texture mapping units, 24 raster output units, and 12 ray tracing cores; tensor cores are not listed. The NVIDIA RTX 3500 Mobile Ada Generation carries 5120 shading units, 160 TMUs, 64 ROPs, 40 RT cores, and 160 tensor cores. Pixel and texture rates reflect these counts: Intel delivers 60.00 GPixel/s and 120.0 GTexel/s, while NVIDIA achieves 98.88 GPixel/s and 247.2 GTexel/s. Floating-point throughput also differs markedly. The Intel part reaches 7.680 TFLOPS for FP32 and 15.36 TFLOPS for FP16 at a 2:1 ratio. The NVIDIA part hits 15.82 TFLOPS for both FP32 and FP16 at a 1:1 ratio.

Power and interface specifications separate the two further. The Intel Arc Pro B390 has a TDP of 80 W, while the NVIDIA RTX 3500 Mobile Ada Generation is rated at 100 W. Both are IGP-style slot widths with no power connectors. The bus interface differs: Intel uses IGP, whereas NVIDIA uses PCIe 4.0 x16. Display outputs are portable device dependent for both. API support is identical across DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The release dates are far apart, with the Intel part dated 2026-01-26 and the NVIDIA part dated 2023-03-20. The Intel predecessor is HD Graphics-WM, while the NVIDIA predecessor is Ampere-MW and its successor is Blackwell-MW.

Where Each One Wins

Without head-to-head benchmark data, the analysis relies on specification differences to infer likely strengths. The NVIDIA RTX 3500 Mobile Ada Generation holds advantages in raw compute throughput. Its FP32 performance of 15.82 TFLOPS is more than double the Intel Arc Pro B390's 7.680 TFLOPS, indicating a substantial lead in general-purpose shader workloads. Texture rate follows a similar pattern: 247.2 GTexel/s versus 120.0 GTexel/s, a 2.06x advantage for NVIDIA. Pixel rate favors NVIDIA as well, at 98.88 GPixel/s versus 60.00 GPixel/s, a 1.65x margin. These numbers suggest NVIDIA would dominate fill-rate-bound scenes and compute-heavy tasks such as rendering, simulation, or machine learning inference, especially with 160 tensor cores available versus none listed for Intel.

The NVIDIA part also wins on memory bandwidth. Its dedicated 432.0 GB/s GDDR6 implementation, backed by 12 GB of VRAM, provides predictable performance independent of system memory. The Intel Arc Pro B390's system shared memory approach means bandwidth and capacity vary with the host platform, introducing uncertainty in memory-intensive applications. For workloads that require large datasets or high memory throughput, the NVIDIA design offers a clear structural advantage.

The Intel Arc Pro B390 counters with efficiency and integration advantages. Its 80 W TDP is 20 W lower than NVIDIA's 100 W rating, which could translate into better thermal behavior in constrained mobile chassis. The 3 nm process node, versus 5 nm for NVIDIA, suggests a more advanced manufacturing technology that may improve power efficiency per unit of compute. The Intel part's higher boost clock of 2500 MHz, compared to 1545 MHz for NVIDIA, indicates a different clock strategy, likely favoring burst workloads that respond well to frequency spikes. Its 12 RT cores, while fewer than NVIDIA's 40, still provide ray tracing capability, and the 2:1 FP16 ratio means half-precision workloads run at twice the FP32 rate, which could benefit certain AI or graphics tasks if supported.

The bus interface also differentiates use cases. Intel uses IGP, meaning it is integrated into the processor and shares system resources, which suits compact, unified memory designs. NVIDIA uses PCIe 4.0 x16, a discrete interface that allows for dedicated VRAM and higher bandwidth to the host, favoring expandability and consistent performance. The NVIDIA part's 5120 shading units and 160 TMUs versus Intel's 1536 and 48, respectively, underscore a massive parallel compute advantage. In practical terms, the NVIDIA RTX 3500 Mobile Ada Generation appears positioned for demanding professional workloads such as 3D modeling, video editing, and AI inference. The Intel Arc Pro B390 appears suited for lightweight graphics tasks, integrated systems, and scenarios where lower power draw and advanced process technology matter more than peak throughput.
