Intel Arc B390 vs Intel Arc Graphics 112EU Mobile Comparison

Where Each One Wins

The Intel Arc B390 and the Intel Arc Graphics 112EU Mobile occupy different performance tiers based on the recorded data. The Arc B390 holds a decisive advantage in raw compute throughput, delivering 7.680 TFLOPS of FP32 performance compared to 3.942 TFLOPS for the 112EU Mobile. This is a 95% higher floating-point output, which directly translates into the B390's measured 3DMark Steel Nomad DX12 score of 1482, a result that places it in the 9th percentile of all GPUs in the database.

The Arc Graphics 112EU Mobile, by contrast, has no recorded benchmark scores in the database, and its average benchmark score is listed as zero. Its percentile ranking of 50th among all GPUs is based on its feature set and specifications rather than observed performance data. The B390 therefore wins every measurable performance category: pixel rate, texture rate, FP32 compute, and FP16 compute. The B390 outputs 60.00 GPixel/s against 52.80 GPixel/s for the 112EU, a 13.6% advantage in pixel throughput. In texture rate, the 112EU counters slightly with 123.2 GTexel/s versus 120.0 GTexel/s for the B390, a 2.7% margin, though this does not overcome the B390's lead in other areas.

The B390 also supports DirectX 12 Ultimate with feature level 12_2, while the 112EU Mobile is limited to DirectX 12 with feature level 12_1. This means the B390 exposes additional hardware features required by the latest DirectX 12 Ultimate titles, whereas the 112EU does not. The B390 also includes 12 dedicated ray tracing cores; the 112EU's ray tracing core count is not recorded in the database.

Architecture Differences

Both GPUs are built on Intel's Xe-LPG architecture, but they differ substantially in implementation. The Arc B390 uses the Panther Lake chip and belongs to the Arc Graphics-M (Panther Lake) generation, fabricated on Intel's 3 nm process. The Arc Graphics 112EU Mobile uses the Meteor Lake chip and belongs to the Arc Graphics-M (Meteor Lake) generation, fabricated on Intel's 10 nm process. The 3 nm node gives the B390 a newer manufacturing base, which contributes to its higher boost clock of 2500 MHz versus 2200 MHz for the 112EU, a 13.6% frequency advantage.

The B390 packs 1536 shading units into its design, while the 112EU Mobile has 896 shading units, a difference of 640 units. This 71% higher shader count is the primary driver of the B390's 95% FP32 advantage. The texture unit counts are inverted: the B390 has 48 texture mapping units, while the 112EU has 56, which explains the 112EU's small lead in texture rate. Both GPUs share the same 24 raster operation units, so pixel output differences come down to clock speed rather than ROP count.

The B390 includes 12 ray tracing cores, a feature absent from the 112EU's recorded specification sheet. Neither GPU lists tensor cores. The B390's TDP is 80 W, while the 112EU Mobile draws 65 W, a 15 W difference. Both are integrated graphics parts with a slot width of IGP, meaning they share system memory rather than using dedicated VRAM. Their memory configurations are identical in kind: system shared memory, system shared bus width, and system dependent bandwidth. The B390 uses an IGP bus interface, while the 112EU uses a Ring Bus interface, reflecting their different chip designs.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two GPUs. The only recorded performance measurement is the Arc B390's 3DMark Steel Nomad DX12 score of 1482. This result places the B390 in the 9th percentile of all GPUs, a low overall standing that reflects the integrated nature of the part rather than its relative position against the 112EU.

The B390's nearest rivals in the database are all discrete NVIDIA parts from older generations. The NVIDIA GeForce GT 520MX scores 1463, which is 1.3% lower than the B390. The NVIDIA GeForce 800M scores 1460, 1.5% lower. The NVIDIA GeForce GT 625 OEM scores 1446, 2.5% lower. The NVIDIA GeForce GT 710 scores 1443, 2.7% lower. These deltas show the B390 sits marginally above a cluster of legacy entry-level discrete GPUs, with its largest recorded lead being 2.7% over the GT 710.

The 112EU Mobile has no rival data and no benchmark scores in the database. Its 50th percentile ranking is not derived from measured performance but from its specification profile. The B390's 9th percentile ranking, by contrast, is anchored to an actual 3DMark result. The compute figures reinforce the B390's superiority: its 7.680 TFLOPS FP32 is 1.95 times the 112EU's 3.942 TFLOPS, and its 15.36 TFLOPS FP16 is 1.95 times the 112EU's 7.885 TFLOPS. The B390's pixel rate of 60.00 GPixel/s exceeds the 112EU's 52.80 GPixel/s by 13.6%, while the 112EU's texture rate of 123.2 GTexel/s exceeds the B390's 120.0 GTexel/s by 2.7%.

The Verdict

The data supports a clear choice for compute-heavy workloads. The Intel Arc B390 outperforms the Intel Arc Graphics 112EU Mobile in every measured performance category except texture rate. Its 7.680 TFLOPS FP32 output nearly doubles the 112EU's 3.942 TFLOPS, and its 1482 3DMark Steel Nomad score provides an actual performance anchor that the 112EU lacks entirely. The B390's 12 ray tracing cores and DirectX 12 Ultimate support make it the more capable part for modern graphics features.

The 112EU Mobile retains one narrow advantage: its 123.2 GTexel/s texture rate edges out the B390's 120.0 GTexel/s. This is a 2.7% margin that does not translate into any recorded benchmark win. The 112EU also draws 15 W less power, which may matter in constrained mobile chassis, but its lower shading unit count, lower boost clock, and older 10 nm process leave it behind in raw throughput.

The B390 is the part to select when maximum integrated graphics performance is the priority. Its 3 nm process, higher clock, and 1536 shading units deliver the highest recorded score in this comparison. The 112EU Mobile is the appropriate choice only when power draw is the limiting factor, as its 65 W TDP is the lower of the two. For all other metrics, the B390's measured performance and feature set dominate the comparison.
