Architecture Differences

The Intel Arc Pro B390 is built on Intel's Panther Lake chip with the Xe3-LPG architecture, fabricated on a 3 nm process at Intel's own foundry. The NVIDIA GeForce RTX 5060 Mobile uses the GB206 chip with Blackwell 2.0 architecture, manufactured by TSMC on a 5 nm process. Intel's transistor count and die size are listed as unknown, while NVIDIA discloses 21,900 million transistors on a 181 mm² die, resulting in a density of 121.0M transistors per mm².

The compute configurations diverge sharply. The Arc Pro B390 has 1536 shading units, 48 TMUs, and 24 ROPs, alongside 12 ray tracing cores. The RTX 5060 Mobile has 3328 shading units, 104 TMUs, and 48 ROPs, with 26 ray tracing cores and 104 tensor cores. The Intel part has no tensor core count listed, while the NVIDIA chip's tensor cores are central to its Blackwell feature set.

Clock speeds tell a different story. The Arc Pro B390 runs at a 300 MHz base clock and boosts to 2500 MHz. The RTX 5060 Mobile has a 952 MHz base and 1455 MHz boost. Despite lower clocks, the NVIDIA part achieves higher throughput due to its larger shader array. Memory configurations are fundamentally different: the Intel GPU uses system-shared memory with system-dependent bandwidth, while the NVIDIA part has 8 GB of GDDR7 on a 128-bit bus with 384.0 GB/s.

The process node gap is significant. Intel's 3 nm process is one generation ahead of TSMC's 5 nm node used for the RTX 5060 Mobile. However, the NVIDIA design compensates with a much larger compute footprint. The Intel part has a 60.00 GPixel/s pixel rate and 120.0 GTexel/s texture rate, while the NVIDIA part delivers 69.84 GPixel/s and 151.3 GTexel/s, respectively.

Power characteristics differ notably. The Arc Pro B390 is rated at 80 W TDP, while the RTX 5060 Mobile is rated at 45 W. Both are IGP-class solutions with no power connectors, but the bus interfaces differ: Intel uses IGP, while NVIDIA uses PCIe 5.0 x16. Both GPUs have portable-device-dependent display outputs.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the Arc Pro B390 and the RTX 5060 Mobile, so the comparison relies on the recorded measurements for the NVIDIA part and the Intel part's specification-derived performance profile.

The RTX 5060 Mobile's average benchmark score is 22435, placing it at the 67th percentile of all GPUs. Its nearest rival, the AMD Radeon RX 7700 XT, scores 22549, which is 0.5% higher. The NVIDIA part also sits 1.3% above the AMD Radeon RX 5700 (22170) and 1.3% above the AMD Radeon RX 6700S (22154). The closest competitor is the NVIDIA GeForce RTX 4060 Mobile at 22729, which is 1.3% higher than the 5060 Mobile's score.

Breaking down the RTX 5060 Mobile's individual benchmarks: it scores 3013.5 in 3DMark Steel Nomad DX12, 96969 in Geekbench OpenCL, and 96451 in Geekbench Vulkan. In Passmark tests, it records 119 in DirectX 10, 168 in DirectX 11, 87 in DirectX 12, 203 in DirectX 9, 876 in G2D, 18852 in G3D, and 7607 in GPU compute.

The Arc Pro B390 has no benchmark scores recorded in the database and no nearest rivals listed. Its percentile rank of 50 suggests it sits at the median of all GPUs, but without measured results, direct numerical comparisons are impossible. The Intel part's specification sheet shows it trails in FP32 throughput (7.680 TFLOPS vs 9.684 TFLOPS) but leads in FP16 (15.36 TFLOPS vs 9.684 TFLOPS), assuming the 2:1 ratio is fully utilized.

In terms of raw rasterization rates, the RTX 5060 Mobile holds a 16.4% advantage in pixel rate (69.84 vs 60.00 GPixel/s) and a 26.1% advantage in texture rate (151.3 vs 120.0 GTexel/s). The NVIDIA part also has more than double the shader units (3328 vs 1536), more than double the TMUs (104 vs 48), and double the ROPs (48 vs 24).

The Verdict

The recorded data shows a clear performance hierarchy. The RTX 5060 Mobile delivers substantially higher raw compute in FP32, higher pixel and texture throughput, and has a validated average benchmark score of 22435 with a 67th percentile ranking. The Arc Pro B390, with no recorded benchmarks and a 50th percentile rank, cannot match these measured results.

For applications that rely on FP32 shader performance, DirectX 12 gaming, or general GPU compute, the RTX 5060 Mobile is the stronger choice. Its 26.1% FP32 advantage and 16.4% pixel rate lead are decisive in most rendering workloads. The NVIDIA part also benefits from dedicated 8 GB GDDR7 memory with 384.0 GB/s bandwidth, which eliminates the system-dependency of the Intel part's shared memory architecture.

The Arc Pro B390 has specific strengths. Its FP16 throughput of 15.36 TFLOPS is 58.6% higher than the RTX 5060 Mobile's 9.684 TFLOPS, making it potentially better suited for half-precision compute tasks. Its 2500 MHz boost clock is substantially higher than the NVIDIA part's 1455 MHz, and the 3 nm process node offers architectural efficiency advantages.

Power consumption is a differentiator. The RTX 5060 Mobile's 45 W TDP is 43.75% lower than the Arc Pro B390's 80 W, making the NVIDIA part more suitable for thin-and-light laptops where thermal and battery constraints are tight. The Intel part's higher power envelope may allow sustained clocks but at the cost of system-level thermal management.

The database's percentile data reinforces the RTX 5060 Mobile's position. At the 67th percentile, it outperforms the majority of GPUs in the database, while the Arc Pro B390 sits at the median. Without benchmark scores for the Intel part, its real-world performance remains unverified, and the specification sheet alone does not indicate parity with the NVIDIA part in standard workloads.

Specification Differences

The two GPUs differ in every major specification category. The Intel Arc Pro B390 uses a 3 nm process at Intel's foundry, while the NVIDIA GeForce RTX 5060 Mobile uses a 5 nm process at TSMC. NVIDIA discloses 21,900 million transistors on a 181 mm² die, while Intel lists its transistor count and die size as unknown.

Memory configurations are entirely different. The Arc Pro B390 uses system-shared memory with system-dependent bandwidth and type. The RTX 5060 Mobile uses 8 GB of GDDR7 on a 128-bit bus with 384.0 GB/s bandwidth, clocked at 1500 MHz (24 Gbps effective).

Compute unit counts favor the NVIDIA part: 3328 shading units vs 1536, 104 TMUs vs 48, 48 ROPs vs 24, 26 ray tracing cores vs 12, and 104 tensor cores vs none listed. Clock speeds favor the Intel part: 300 MHz base and 2500 MHz boost vs 952 MHz base and 1455 MHz boost.

Throughput rates split between the two: the Intel part has 7.680 TFLOPS FP32 and 15.36 TFLOPS FP16 (2:1), while the NVIDIA part has 9.684 TFLOPS FP32 and 9.684 TFLOPS FP16 (1:1). Pixel rates are 60.00 GPixel/s for Intel and 69.84 GPixel/s for NVIDIA. Texture rates are 120.0 GTexel/s for Intel and 151.3 GTexel/s for NVIDIA.

Power and interface specs differ: the Arc Pro B390 has an 80 W TDP and IGP bus interface, while the RTX 5060 Mobile has a 45 W TDP and PCIe 5.0 x16 bus interface. Both have no power connectors and portable-device-dependent display outputs. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.
