Architecture Differences

The Intel Arc 130V Mobile and Intel Arc Pro B390 represent two distinct generations of Intel integrated graphics. The 130V Mobile uses the Lunar Lake chip with the Xe2-LPG architecture, part of the Arc Graphics-M (Lunar Lake) generation. The Arc Pro B390 uses the Panther Lake chip with the Xe3-LPG architecture, belonging to the Arc Graphics-WM (Panther Lake) generation. This architectural leap from Xe2-LPG to Xe3-LPG introduces a different instruction pipeline and execution layout.

Both processors are fabricated on a 3 nm process, but the foundries differ. The 130V Mobile is manufactured by TSMC, while the Arc Pro B390 is manufactured by Intel. The die size for the 130V Mobile is 172 mm², whereas the die size for the B390 is not recorded in the database. Transistor counts are unknown for both parts.

The shading unit configuration changes significantly between generations. The B390 packs 1536 shading units, a 71.4% increase over the 896 units on the 130V Mobile. However, the texture mapping unit count drops from 56 on the older part to 48 on the newer one, and the raster output units decrease from 28 to 24. The ray tracing core count rises from 7 to 12, representing a substantial increase in dedicated RT hardware.

Clock behavior also differs. Both GPUs share a 300 MHz base clock, but the boost clock jumps from 1850 MHz on the 130V Mobile to 2500 MHz on the B390. This 650 MHz higher boost ceiling, combined with the larger shader array, drives the B390's compute advantage.

Memory architecture is identical in description: system shared memory, system shared bus width, and system dependent bandwidth. Neither GPU has dedicated VRAM. The slot width is IGP for both, and the bus interface is also IGP. The B390 lists no power connectors, while the 130V Mobile does not specify any.

Power envelopes differ substantially. The 130V Mobile operates at a 37 W TDP, while the B390 draws up to 80 W. This higher power budget allows the B390 to sustain higher clocks and feed more compute units.

Where Each One Wins

The Arc 130V Mobile wins in areas where its lower power draw and higher ROP/TMU counts matter. With 56 TMUs and 28 ROPs, the 130V Mobile offers more texture filtering and pixel output hardware per compute unit. Its 51.80 GPixel/s pixel rate and 103.6 GTexel/s texture rate indicate that for certain fill-rate limited workloads, the older architecture retains an edge. The 37 W TDP makes it suitable for power constrained mobile designs where thermal and battery limits are tight.

The Arc Pro B390 wins in raw compute throughput. Its 1536 shading units at a 2500 MHz boost clock deliver 7.680 TFLOPS of FP32 performance, more than double the 3.315 TFLOPS of the 130V Mobile. FP16 performance follows the same pattern: 15.36 TFLOPS versus 6.630 TFLOPS. The B390 also holds the advantage in ray tracing with 12 RT cores versus 7, and its pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s exceed the 130V Mobile's figures. The higher 80 W TDP enables this performance class.

For applications that rely heavily on compute shaders, neural network inference, or ray traced effects, the B390 is the stronger candidate. For lighter workloads, integrated graphics scenarios with modest power budgets, or situations where texture fill and pixel throughput matter more than raw FP32, the 130V Mobile remains competitive.

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark scores between these two GPUs. The winsA and winsB counters both stand at zero, and the headToHeadBenchmarks array is empty. The avgBenchmarkScore for each is 0, and each holds a percentileVsAllGpus of 50. Without measured performance data, the comparison must rely entirely on the architectural specifications.

The largest compute gap appears in FP32 throughput. The Arc Pro B390 delivers 7.680 TFLOPS, which is 4.365 TFLOPS higher than the 130V Mobile's 3.315 TFLOPS. In relative terms, the B390 offers more than double the single precision compute. FP16 throughput shows a similar disparity: 15.36 TFLOPS versus 6.630 TFLOPS, a difference of 8.73 TFLOPS.

Clock speed contributes significantly to this gap. The B390's 2500 MHz boost clock is 650 MHz higher than the 130V Mobile's 1850 MHz. Combined with a 640 shading unit advantage, the B390's compute advantage is structural rather than incidental.

The pixel rate differential favors the B390 by 8.20 GPixel/s (60.00 versus 51.80). The texture rate differential is 16.4 GTexel/s (120.0 versus 103.6). These differences are smaller in percentage terms than the FP32 gap, indicating that the B390's fill rate advantage is less pronounced than its compute advantage.

Ray tracing hardware shows a clear step up. The B390's 12 RT cores represent a 71.4% increase over the 130V Mobile's 7 RT cores. This suggests meaningfully better performance in ray traced workloads, though no benchmark scores confirm the magnitude.

Power consumption scales with capability. The B390's 80 W TDP is 43 W higher than the 130V Mobile's 37 W. The performance per watt relationship cannot be derived from the available data, but the B390's higher power envelope aligns with its higher clock and larger shader array.

The release timeline shows a generation gap. The 130V Mobile launched on 2024-09-23, while the B390 arrived on 2026-01-26. The predecessor chain follows: HD Graphics-M for the 130V Mobile and HD Graphics-WM for the B390. Both remain in active production status.

The 130V Mobile's 172 mm² die size is the only physical dimension recorded. The B390's die size, transistor count, and transistor density are all unspecified. This limits physical comparison between the two chips beyond the process node and foundry information.

In the absence of benchmark scores, the specification sheet tells the story. The Arc Pro B390 is positioned as the higher performance part with more shading units, higher clocks, more RT cores, and double the FP32 throughput. The Arc 130V Mobile retains advantages in TMU count, ROP count, lower TDP, and a documented die size. Each part serves a different performance and power segment within Intel's integrated graphics lineup.
