Intel Arc 140V Mobile vs Intel Arc B390 Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark comparisons between the Intel Arc 140V Mobile and the Intel Arc B390. The database lists a single benchmark result for the Arc B390, while the Arc 140V Mobile has no benchmark scores recorded. This limits direct numerical comparison, but the available data still allows for meaningful analysis through specification differences and the Arc B390's performance relative to its nearest rivals.

The Intel Arc B390 delivers a 3DMark Steel Nomad DX12 score of 1482. This places it at the 9th percentile among all GPUs in the database, indicating that it sits in the lower performance tier overall. Its nearest rivals in the database are the NVIDIA GeForce GT 520MX with an average score of 1463, the NVIDIA GeForce 800M at 1460, the NVIDIA GeForce GT 625 OEM at 1446, and the NVIDIA GeForce GT 710 at 1443. The Arc B390 leads the GT 520MX by 1.3 percent, the GeForce 800M by 1.5 percent, the GT 625 OEM by 2.5 percent, and the GT 710 by 2.7 percent. These are modest margins, showing that the Arc B390 performs within a narrow band above these older discrete mobile GPUs.

The Arc 140V Mobile has no benchmark scores in the database, so its percentile ranking and average score are recorded as zero. This means no direct performance verdict can be derived from measured results for that part. However, the specification data provides a basis for estimating relative capability.

Where Each One Wins

Based on the recorded specifications, the Intel Arc B390 holds clear advantages in raw compute throughput. It features 1536 shading units versus 1024 on the Arc 140V Mobile, a 50 percent increase in shader count. This translates directly into FP32 performance: the Arc B390 delivers 7.680 TFLOPS compared to 3.994 TFLOPS on the Arc 140V Mobile, making the B390 roughly 92 percent faster in single-precision floating-point work. FP16 performance follows the same pattern, with the B390 achieving 15.36 TFLOPS versus 7.987 TFLOPS on the 140V Mobile, again a 2:1 ratio in both cases.

The Arc B390 also has more ray tracing cores, with 12 RT cores versus 8 on the 140V Mobile. This suggests stronger ray-traced workload capability, though no benchmark data confirms real-world scaling. The B390's boost clock is also higher at 2500 MHz compared to 1950 MHz on the 140V Mobile, a 28 percent increase in peak clock speed.

The Arc 140V Mobile wins in texture and pixel throughput efficiency despite its lower shader count. It has 64 texture mapping units versus 48 on the B390, and 32 raster output pipelines versus 24. The 140V Mobile achieves a pixel rate of 62.40 GPixel/s, slightly above the B390's 60.00 GPixel/s. Its texture rate of 124.8 GTexel/s also edges out the B390's 120.0 GTexel/s. These wins come despite the 140V Mobile's lower clock speeds, indicating that its smaller shader array paired with more TMUs and ROPs yields better fill-rate performance per clock.

Power consumption heavily favors the Arc 140V Mobile. Its TDP is 37 W, less than half of the B390's 80 W. For integrated graphics in portable devices, this efficiency difference is substantial. The 140V Mobile achieves its fill-rate advantages while drawing significantly less power, which points to better performance-per-watt in rasterization-bound tasks.

Architecture Differences

The two GPUs belong to different Intel architecture generations. The Intel Arc 140V Mobile uses the Lunar Lake chip with the Xe2-LPG architecture, part of the Arc Graphics-M (Lunar Lake) generation. The Intel Arc B390 uses the Panther Lake chip with the Xe3-LPG architecture, part of the Arc Graphics-M (Panther Lake) generation.

Both are built on a 3 nm process node, but they use different foundries. The Arc 140V Mobile is fabricated by TSMC, while the Arc B390 is fabricated by Intel. The die size for the 140V Mobile is 172 mm², while the B390's die size is listed as unknown. Transistor counts are unknown for both parts.

The shading unit configuration differs significantly. The B390 uses 1536 shading units arranged with 48 TMUs and 24 ROPs. The 140V Mobile uses 1024 shading units with 64 TMUs and 32 ROPs. This represents a different balance between compute and fixed-function throughput. The B390 allocates more silicon to shader compute and ray tracing, while the 140V Mobile allocates more to texture and pixel processing.

Ray tracing hardware also differs. The B390 has 12 RT cores, a 50 percent increase over the 140V Mobile's 8 RT cores. Neither GPU lists tensor cores in the database.

Memory configurations are identical in structure: both use System Shared memory with a System Shared bus width and System Dependent bandwidth. The database provides no discrete memory size, type, or bandwidth figures for either part.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. They share the same API feature set.

The Verdict

The data presents two integrated GPUs with distinctly different design priorities. The Intel Arc B390 focuses on compute throughput. It has 50 percent more shading units, 50 percent more ray tracing cores, and a 28 percent higher boost clock than the Arc 140V Mobile. Its FP32 performance of 7.680 TFLOPS nearly doubles the 140V Mobile's 3.994 TFLOPS. For workloads that scale with shader count and raw floating-point math, the B390 is clearly the stronger part.

The Arc 140V Mobile prioritizes efficiency and fill-rate balance. Its 37 W TDP is less than half of the B390's 80 W, yet it achieves higher pixel and texture rates. The 140V Mobile's 64 TMUs and 32 ROPs give it a fill-rate advantage that the B390's higher clocks and shader count cannot overcome in those specific metrics. This makes the 140V Mobile better suited to power-constrained designs where rasterization throughput per watt matters more than peak compute.

The benchmark data shows the B390 at the 9th percentile overall, a low standing that reflects its integrated nature rather than absolute capability. Its 3DMark Steel Nomad score of 1482 places it just ahead of several older NVIDIA discrete mobile GPUs, all within a narrow 1.3 to 2.7 percent margin. This indicates that the B390's compute advantages over the 140V Mobile do not necessarily translate into a large real-world performance gap in standardized tests, though no direct comparison data exists.

The Arc 140V Mobile, with no recorded benchmarks, cannot be positioned against the B390 or any other GPU using measured results. Its specification profile suggests a balanced integrated solution with strong efficiency, while the B390's profile indicates a higher-power, higher-compute variant that trades efficiency for shader throughput. The B390 also carries the newer Xe3-LPG architecture and a later release date, while the 140V Mobile uses the earlier Xe2-LPG design.

For portable devices where thermals and battery life constrain the design, the Arc 140V Mobile's 37 W TDP and superior fill rates make it the logical choice. For compute-oriented tasks where power budget is less restrictive, the Arc B390's 7.680 TFLOPS and 12 RT cores provide substantially more headroom. The database records no direct wins for either part, so the verdict rests on specification analysis: the B390 wins on compute, the 140V Mobile wins on efficiency and fill-rate metrics.
