Intel Arc B390 vs Intel Arc Pro B390 Comparison

The Intel Arc B390 and Intel Arc Pro B390 are two integrated graphics processors built on the same Panther Lake chip and Xe3-LPG architecture. Both are designed for portable devices, sharing identical core configurations and clock speeds. The recorded data shows that while they share nearly every specification, their positioning differs in terms of benchmark presence and percentile ranking. The database contains a single benchmark score for the Arc B390, while the Arc Pro B390 has no recorded benchmark scores. This asymmetry shapes the analysis below.

Where Each One Wins

The Arc B390 holds a clear advantage in recorded performance data. It has a 3DMark Steel Nomad DX12 score of 1482, placing it in the 9th percentile among all GPUs in the database. That percentile indicates that 91% of recorded GPUs score higher, so the Arc B390 occupies a low-performance tier. Its nearest rivals are the NVIDIA GeForce GT 520MX, which scores 1463 on average (1.3% behind), the NVIDIA GeForce 800M at 1460 (1.5% behind), the NVIDIA GeForce GT 625 OEM at 1446 (2.5% behind), and the NVIDIA GeForce GT 710 at 1443 (2.7% behind). The Arc B390 leads all four by a narrow margin, with the largest gap being 2.7% over the GT 710.

The Arc Pro B390 has zero benchmark scores in the database. Its average benchmark score is 0, and it has no nearest rivals listed. This means no direct performance wins can be attributed to it from recorded measurements. The data does not show any test where the Arc Pro B390 outperforms the Arc B390 or any other GPU. Its percentile versus all GPUs is listed at 50, which is a positional ranking rather than a performance-derived score. The 50th percentile suggests a median placement among all GPUs, but without an actual score, that ranking cannot be tied to any specific workload result.

In terms of wins in head-to-head benchmarks, the database records 0 wins for each part. With no head-to-head benchmark entries, neither product can claim a measured victory over the other. The only measurable outcome comes from the single 3DMark Steel Nomad DX12 run for the Arc B390. That test is a DX12 workload, so it indicates the Arc B390 can complete that specific benchmark, while the Arc Pro B390 has no corresponding result.

Architecture Differences

Both GPUs use the identical Panther Lake chip, fabricated on Intel's 3 nm process. The architecture is Xe3-LPG for both, with the Arc B390 belonging to the Arc Graphics-M (Panther Lake) generation and the Arc Pro B390 belonging to the Arc Graphics-WM (Panther Lake) generation. The core layout is exactly the same: 1536 shading units, 48 texture mapping units, 24 raster operation pipelines, and 12 ray tracing cores. No tensor core count is listed for either part.

Clock behavior is also identical. Both run at a base clock of 300 MHz and a boost clock of 2500 MHz. Memory configuration is system shared for both, with the bus width and bandwidth dependent on the host system. The memory clock is listed as system shared as well, meaning there is no dedicated VRAM on either chip. This design choice ties performance directly to the platform's main memory subsystem.

Compute rates match precisely. The pixel rate is 60.00 GPixel/s for both, the texture rate is 120.0 GTexel/s for both, and the FP32 throughput is 7.680 TFLOPS for both. FP16 throughput is 15.36 TFLOPS with a 2:1 ratio for both, indicating that half-precision operations run at twice the rate of single-precision operations. The thermal design power is 80 W for both, with no power connectors required because they are integrated graphics processors.

The API support is identical: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The slot width is IGP for both, and the bus interface is IGP as well. Display outputs are portable device dependent for both, meaning the specific connectors depend on the laptop or handheld design. The production status is active for both, with the same release date of 2026-01-26.

The only architectural difference recorded is the generation label and the predecessor. The Arc Pro B390 lists HD Graphics-WM as its predecessor, while the Arc B390 has no predecessor listed. This suggests a lineage difference: the Pro version traces back to the older HD Graphics-WM line, while the non-Pro version has no recorded ancestry in the database. No other specification differs.

The Verdict

Based strictly on the recorded data, the Arc B390 is the only one of the two with any measurable performance. Its 3DMark Steel Nomad DX12 score of 1482 is a real result, and it compares favorably within a narrow band of low-end NVIDIA parts. The Arc B390 sits 1.3% above the GT 520MX, 1.5% above the 800M, 2.5% above the GT 625 OEM, and 2.7% above the GT 710. These are small margins, but they are consistent wins across all four nearest rivals.

The Arc Pro B390 has no benchmark scores, no rival comparisons, and no measurable wins. Its 50th percentile ranking is the only positional data, but that percentile does not correspond to any actual score or test result. A user looking at the database would find no evidence of its performance in any workload.

For any application-specific choice, the data points to the Arc B390 as the part with demonstrated capability. The Pro designation does not translate into any recorded performance advantage. The identical core counts, clocks, memory setup, and API support mean that the two parts are architecturally indistinguishable in every measured dimension except for the existence of a benchmark score. Without a score for the Arc Pro B390, there is no basis to claim it performs better or worse. The verdict from the data is straightforward: the Arc B390 has a measurable performance profile, while the Arc Pro B390 does not have one in this database.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the Arc B390 and Arc Pro B390. There are zero wins recorded for either side. Consequently, any direct comparison must rely on the single available score for the Arc B390 and the absence of scores for the Arc Pro B390.

The Arc B390's 1482 score in 3DMark Steel Nomad DX12 is the only concrete measurement. That score places it at the 9th percentile among all GPUs. The nearest rival, the NVIDIA GeForce GT 520MX, has an average score of 1463, which puts the Arc B390 1.3% ahead. The NVIDIA GeForce 800M averages 1460, putting the Arc B390 1.5% ahead. The NVIDIA GeForce GT 625 OEM averages 1446, putting the Arc B390 2.5% ahead. The NVIDIA GeForce GT 710 averages 1443, putting the Arc B390 2.7% ahead.

These deltas are small but uniform. The Arc B390 wins by the largest margin over the GT 710, and by the smallest margin over the GT 520MX. The pattern indicates that the Arc B390 sits at the upper end of a very low-performance cluster. Its 9th percentile ranking confirms that it is not competitive with mainstream or high-end GPUs, but it does outperform several older discrete low-end parts.

The Arc Pro B390 has no such data. Its average benchmark score is 0, and its nearest rivals list is empty. The 50th percentile ranking is listed, but that cannot be validated against any test result. The absence of a Steel Nomad score means there is no way to say whether the Pro version would match, exceed, or fall short of the Arc B390's 1482.

The FP32 throughput of 7.680 TFLOPS is identical for both, as are the texture rate of 120.0 GTexel/s and pixel rate of 60.00 GPixel/s. Since the clock speeds and core counts are identical, the theoretical peak performance is the same. The only recorded difference is the benchmark result: one part has it, the other does not. Without a measured score for the Arc Pro B390, the head-to-head analysis is one-sided. The Arc B390 demonstrates a real result against known rivals, while the Arc Pro B390 offers no comparable measurement.
