Intel Arc Pro B390 vs NVIDIA GeForce RTX 4060 Mobile Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark comparison between the Intel Arc Pro B390 and the NVIDIA GeForce RTX 4060 Mobile. The database lists zero wins for either part in this pairing, and no benchmark entries appear for the Intel Arc Pro B390. However, the RTX 4060 Mobile has a full benchmark profile, and its performance can be contextualized through its nearest rivals in the database.

The RTX 4060 Mobile posts an average benchmark score of 22,729 across nine tests. This places it at the 67th percentile among all GPUs tracked in the database. Its nearest rival, the NVIDIA GeForce RTX 2080, averages 22,895, which puts the RTX 4060 Mobile 0.7% behind that desktop card. The AMD Radeon RX 7700 XT averages 22,549, meaning the RTX 4060 Mobile leads it by 0.8%. The Intel Arc B580 averages 23,021, placing the RTX 4060 Mobile 1.3% behind that rival. The NVIDIA GeForce RTX 5060 Mobile averages 22,435, and the RTX 4060 Mobile leads it by 1.3%.

Per-test results for the RTX 4060 Mobile show its strongest showing in Passmark's DirectX 9 test with a score of 216. The DirectX 11 test yields a score of 157, while the DirectX 10 test produces 107. The DirectX 12 test returns a notably lower score of 73. In general-purpose compute, the Passmark GPU Compute test records 6,816. The Passmark G3D test, which aggregates gaming-oriented workloads, returns 17,469. The G2D test for 2D graphics operations scores 730. Geekbench OpenCL and Vulkan tests return 89,420 and 89,569, respectively.

The Intel Arc Pro B390 has no benchmark scores recorded in the database, an average benchmark score of zero, and no nearest rivals listed. It sits at the 50th percentile among all GPUs, which reflects its position as a midpoint in the database's distribution, but without measured results, no direct comparison of raw scores is possible.

Architecture Differences

The two GPUs diverge fundamentally in their underlying designs. The Intel Arc Pro B390 uses the Panther Lake chip with the Xe3-LPG architecture, built on a 3 nm process at Intel's foundry. The NVIDIA GeForce RTX 4060 Mobile uses the AD107 chip with Ada Lovelace architecture, fabricated on a 5 nm process at TSMC. The RTX 4060 Mobile's transistor count is documented at 18,900 million, with a die size of 159 mm² and a transistor density of 118.9M per mm². The Arc Pro B390's transistor count and die size are listed as unknown, so no density comparison is possible.

Clock behavior differs substantially. The Arc Pro B390 has a base clock of 300 MHz and a boost clock of 2,500 MHz. The RTX 4060 Mobile runs a base clock of 1,545 MHz and a boost clock of 1,890 MHz. The Arc Pro B390's base clock is far lower, but its boost clock is 610 MHz higher than the NVIDIA part's boost. Memory clocking also differs: the Arc Pro B390 uses system-shared memory with a system-dependent bandwidth, while the RTX 4060 Mobile uses 8 GB of GDDR6 at 2,000 MHz (16 Gbps effective) across a 128-bit bus, yielding 256.0 GB/s of bandwidth.

Compute resources show a clear disparity. The Arc Pro B390 packs 1,536 shading units, 48 texture mapping units, and 24 ROPs. The RTX 4060 Mobile doubles several of these counts: 3,072 shading units, 96 TMUs, and 48 ROPs. Ray tracing cores also differ: the Arc Pro B390 has 12, while the RTX 4060 Mobile has 24. The NVIDIA part additionally includes 96 tensor cores, a feature the Intel part does not list. The Arc Pro B390's FP32 throughput is 7.680 TFLOPS, with FP16 at 15.36 TFLOPS using a 2:1 ratio. The RTX 4060 Mobile delivers 11.61 TFLOPS for both FP32 and FP16, using a 1:1 ratio.

Pixel and texture rates follow the compute resource gap. The Arc Pro B390 reaches 60.00 GPixel/s and 120.0 GTexel/s. The RTX 4060 Mobile reaches 90.72 GPixel/s and 181.4 GTexel/s. The NVIDIA part leads by roughly 51% in pixel throughput and 51% in texture throughput, consistent with its higher ROP and TMU counts.

The bus interface differs as well. The Arc Pro B390 uses an IGP (integrated graphics processor) interface with no power connectors, while the RTX 4060 Mobile uses PCIe 4.0 x8 and also lists no power connectors. Both are marked as IGP slot width, meaning neither uses a discrete expansion slot. The Arc Pro B390's memory is entirely system-shared, whereas the RTX 4060 Mobile has dedicated VRAM.

Power draw is recorded at 80 W for the Arc Pro B390 and 115 W for the RTX 4060 Mobile. The Intel part consumes 35 W less, a meaningful difference for thermally constrained portable devices. Both parts list display outputs as portable device dependent.

API support is identical across the two: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Production status for both is active. The Arc Pro B390's release date is recorded as 2026-01-26, while the RTX 4060 Mobile's is 2023-01-02. The NVIDIA part's predecessor is listed as GeForce 30 Mobile, with the successor being GeForce 50 Mobile. The Intel part's predecessor is HD Graphics-WM, with no successor listed.

Where Each One Wins

The RTX 4060 Mobile's measurable advantages are clear from the recorded data. It offers 8 GB of dedicated GDDR6 memory with 256.0 GB/s of bandwidth, which is essential for texture-heavy workloads and high-resolution rendering where system-shared memory can become a bottleneck. Its 3,072 shading units and 96 TMUs provide roughly double the raw compute and texture throughput of the Arc Pro B390. The 24 ray tracing cores and 96 tensor cores add hardware acceleration for ray-traced effects and AI-based features such as DLSS, which the Intel part cannot match with its 12 ray tracing cores and no listed tensor cores.

The RTX 4060 Mobile also sits at the 67th percentile among all GPUs, with an average benchmark score of 22,729 that places it within 1.3% of the Intel Arc B580, a dedicated desktop card. Its performance is consistent enough to rank above the Radeon RX 7700 XT by 0.8% and above the RTX 5060 Mobile by 1.3% in average score. These results indicate a well-rounded part that competes with desktop mid-range GPUs despite its mobile form factor.

The Arc Pro B390's advantages are more architectural than performance-based. Its 3 nm process node is smaller than the RTX 4060 Mobile's 5 nm node, which typically improves power efficiency per transistor. The 80 W TDP is 35 W lower than the RTX 4060 Mobile's 115 W, making the Intel part more attractive for systems with limited thermal budgets. The higher boost clock of 2,500 MHz versus 1,890 MHz suggests that the Intel part can ramp to higher frequencies in short bursts, though the lower base clock of 300 MHz indicates it idles much lower. The 50th percentile ranking is neutral, reflecting the lack of benchmark data rather than measured performance.

The Arc Pro B390's FP16 throughput of 15.36 TFLOPS (2:1) exceeds its own FP32 rate, indicating it can accelerate half-precision workloads. The RTX 4060 Mobile's FP16 rate matches its FP32 rate at 11.61 TFLOPS (1:1), which means the Intel part has a higher theoretical peak for FP16 compute. This could benefit machine learning inference or scientific workloads that use reduced precision, though the NVIDIA part's tensor cores may provide more practical acceleration for such tasks.

For gaming workloads, the RTX 4060 Mobile's higher pixel rate (90.72 GPixel/s) and texture rate (181.4 GTexel/s) give it a decisive edge in rasterization-heavy scenes. The Passmark DirectX 12 score of 73, while low in absolute terms, still represents measurable performance in modern API workloads. For compute-heavy tasks, the RTX 4060 Mobile's Geekbench OpenCL score of 89,420 and Vulkan score of 89,569 indicate strong general-purpose throughput.

The specification table highlights the structural gap between the two parts. The RTX 4060 Mobile doubles the Intel part in shading units, TMUs, ROPs, and ray tracing cores, and adds tensor cores entirely absent from the Arc Pro B390. The NVIDIA part also has dedicated VRAM with fixed bandwidth, while the Intel part relies on system memory. The Intel part counters with a smaller process node, a higher boost clock, and a lower TDP. API support, slot width, power connectors, display outputs, and production status are identical across both.
