Intel Arc B390 vs NVIDIA GeForce RTX 5060 Mobile Comparison

Head-to-Head Benchmarks

The recorded data contains a single direct comparison between the Intel Arc B390 and the NVIDIA GeForce RTX 5060 Mobile: the 3DMark Steel Nomad DX12 test. The results are decisive. The NVIDIA GeForce RTX 5060 Mobile scores 3013.5 points, while the Intel Arc B390 scores 1482 points. This represents a 50.8% deficit for the Intel part, meaning the NVIDIA GPU delivers roughly double the performance in this specific workload.

The RTX 5060 Mobile’s lead is not marginal. A delta of 50.8% places it in a completely different performance tier. The Intel Arc B390 sits in the 9th percentile of all GPUs in the database, while the RTX 5060 Mobile ranks in the 67th percentile. That percentile gap of 58 points underscores how far apart these two parts are in overall standing.

For context, the Intel Arc B390’s nearest rivals in the database are legacy low-end parts. It scores 1.3% above the NVIDIA GeForce GT 520MX, 1.5% above the NVIDIA GeForce 800M, 2.5% above the NVIDIA GeForce GT 625 OEM, and 2.7% above the NVIDIA GeForce GT 710. These are all sub-1500 score GPUs. The RTX 5060 Mobile, by contrast, trades blows with mid-range and upper-mid-range desktop cards. Its average score of 22435 is within 0.5% of the AMD Radeon RX 7700 XT, 1.2% above the AMD Radeon RX 5700, 1.3% above the AMD Radeon RX 6700S, and 1.3% below the NVIDIA GeForce RTX 4060 Mobile.

The only head-to-head benchmark available shows no ambiguity. The RTX 5060 Mobile wins the sole recorded test, and the margin is overwhelming. The Intel Arc B390 has zero wins in the head-to-head comparison set; the RTX 5060 Mobile has one win.

Where Each One Wins

Based on the recorded data, the NVIDIA GeForce RTX 5060 Mobile wins in every measurable category. It is faster in the only shared benchmark, has a higher average benchmark score, and occupies a far higher percentile ranking. The Intel Arc B390 does not win any benchmark in the database.

However, the two chips are designed for different contexts. The Intel Arc B390 is an integrated graphics processor (IGP) with a 80 W TDP and no power connectors. It is built into a Panther Lake platform and uses system shared memory. The RTX 5060 Mobile is also labeled as IGP in slot width, but it is a discrete-class mobile GPU with its own 8 GB of GDDR7 memory, a 128-bit bus, and 384.0 GB/s of bandwidth. It draws 45 W.

The RTX 5060 Mobile’s wins are not limited to raw rasterization. It also has dedicated tensor cores: 104 of them. The Intel Arc B390 lists no tensor core count. In compute-oriented workloads that leverage tensor operations, the RTX 5060 Mobile has a structural advantage that the Intel part cannot match.

The Intel Arc B390 does have a higher boost clock: 2500 MHz versus 1455 MHz for the RTX 5060 Mobile. It also supports FP16 at a 2:1 ratio, delivering 15.36 TFLOPS, whereas the RTX 5060 Mobile delivers 9.684 TFLOPS in FP16 at a 1:1 ratio. These are narrow wins on paper, but they do not translate into any benchmark victory in the recorded data.

Architecture Differences

The Intel Arc B390 is built on Intel’s Xe3-LPG architecture and uses a 3 nm process node from Intel’s own foundry. It is part of the Arc Graphics-M (Panther Lake) generation. The chip has 1536 shading units, 48 texture mapping units, 24 raster output units, and 12 ray tracing cores. It has no listed tensor cores.

The NVIDIA GeForce RTX 5060 Mobile uses the Blackwell 2.0 architecture on TSMC’s 5 nm process.

The RTX 5060 Mobile has 3328 shading units, 104 TMUs, 48 ROPs, 26 ray tracing cores, and 104 tensor cores.

The Intel part uses system shared memory with no dedicated VRAM, while the RTX 5060 Mobile has 8 GB of GDDR7 on a 128-bit bus. Memory bandwidth for the Intel part is system dependent; the RTX 5060 Mobile has a fixed 384.0 GB/s.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 5060 Mobile connects via PCIe 5.0 x16; the Intel Arc B390 is an IGP with no bus interface beyond the integrated path. Both have portable device dependent display outputs.

The RTX 5060 Mobile has a known predecessor, the GeForce 40 Mobile series. The Intel Arc B390 has no listed predecessor or successor. The RTX 5060 Mobile was released on May 19, 2025; the Intel Arc B390 followed with a release date of January 26, 2026.

The Verdict

The data leaves no room for debate. The NVIDIA GeForce RTX 5060 Mobile is the faster GPU by every recorded metric. It wins the only head-to-head benchmark by 50.8%, holds a 67th percentile ranking versus 9th for the Intel Arc B390, and offers roughly double the shading units, double the ROPs, more than double the ray tracing cores, and dedicated tensor cores that the Intel part lacks.

The RTX 5060 Mobile also achieves this with a lower TDP of 45 W versus 80 W for the Intel Arc B390. It has fixed, high-bandwidth GDDR7 memory, while the Intel part depends on system shared memory with variable bandwidth. The RTX 5060 Mobile’s transistor count of 21,900 million on a 181 mm² die is fully specified, whereas the Intel chip’s transistor count and die size are unknown.

The Intel Arc B390 does have advantages in clock speed and FP16 throughput. Its 2500 MHz boost clock is substantially higher than the RTX 5060 Mobile’s 1455 MHz, and its 15.36 TFLOPS FP16 output exceeds the NVIDIA part’s 9.684 TFLOPS. These specifications do not produce any benchmark win in the recorded data.

For a buyer or system integrator choosing between these two parts, the RTX 5060 Mobile is the clear performance pick. The Intel Arc B390 is an integrated solution with system-shared memory, suited for platforms where the GPU is not the primary focus. The RTX 5060 Mobile is a discrete-class mobile GPU that competes with desktop mid-range cards like the AMD Radeon RX 7700 XT and the NVIDIA GeForce RTX 4060 Mobile.

The database’s percentile rankings reinforce the verdict. A 58-point percentile gap separates the two. The RTX 5060 Mobile sits above the median of all GPUs; the Intel Arc B390 sits near the very bottom. In any application that relies on the GPU, the NVIDIA part is the only rational choice based on the available measurements.
