Intel Arc B390 vs Intel Arc Graphics 64EU Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a single benchmark result for the Intel Arc B390: a 3DMark Steel Nomad DX12 score of 1482. This places the Arc B390 at the 9th percentile among all GPUs in the database. The Intel Arc Graphics 64EU Mobile has no recorded benchmark scores, so direct numerical comparison is limited to the Arc B390's standing against its nearest rivals.

The Arc B390's 1482 score puts it 1.3% ahead of the NVIDIA GeForce GT 520MX (1463), 1.5% ahead of the NVIDIA GeForce 800M (1460), 2.5% ahead of the NVIDIA GeForce GT 625 OEM (1446), and 2.7% ahead of the NVIDIA GeForce GT 710 (1443). These deltas are narrow, indicating that the Arc B390 occupies a performance tier close to those older discrete notebook and desktop parts. The margin between the Arc B390 and the GT 710 is the largest among the listed rivals, but even that gap is small in absolute terms.

Because the Arc Graphics 64EU Mobile has no benchmark entries, the head-to-head comparison rests on architectural and specification data rather than measured scores. The Arc B390's 7.680 TFLOPS FP32 throughput is substantially higher than the 64EU Mobile's 1.792 TFLOPS, a 4.3x difference in raw compute. Pixel rate for the Arc B390 is 60.00 GPixel/s versus 28.00 GPixel/s for the 64EU Mobile, and texture rate is 120.0 GTexel/s versus 56.00 GTexel/s. These numbers indicate the Arc B390 delivers roughly double the fill rate and more than four times the shader throughput.

Architecture Differences

The two GPUs come from different Intel generations and use different architectures. The Intel Arc B390 is built on the Xe3-LPG architecture and belongs to the Arc Graphics-M (Panther Lake) generation. Its chip is Panther Lake, fabricated on a 3 nm process node at Intel. The Intel Arc Graphics 64EU Mobile uses the Xe-LPG architecture from the Arc Graphics-M (Meteor Lake) generation, with a Meteor Lake chip on a 10 nm process node, also from Intel.

Process node differences are significant: 3 nm versus 10 nm suggests the Arc B390 uses a more advanced manufacturing process, which typically allows higher transistor density and improved efficiency for a given power envelope. The Arc B390 has a TDP of 80 W, while the 64EU Mobile is rated at 65 W.

Shader resources differ considerably. The Arc B390 has 1536 shading units, 48 texture mapping units, and 24 raster output units. The 64EU Mobile has 512 shading units, 32 TMUs, and 16 ROPs. The Arc B390 also includes 12 ray tracing cores, while the 64EU Mobile lists no RT cores at all. This means hardware-accelerated ray tracing is present on the Arc B390 but absent on the 64EU Mobile.

API support also diverges. The Arc B390 supports DirectX 12 Ultimate (12_2), whereas the 64EU Mobile supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The DirectX 12 Ultimate designation on the Arc B390 indicates a higher feature level, which aligns with its newer architecture and RT core presence.

Memory configurations are identical in type: both use System Shared memory with System Shared bus width and System Dependent bandwidth. Neither has dedicated VRAM. The bus interface differs, with the Arc B390 using IGP and the 64EU Mobile using Ring Bus, though both are integrated parts with no expansion slot.

Clock behavior shows the Arc B390's boost reaches 2500 MHz versus 1750 MHz for the 64EU Mobile, while both have a 300 MHz base clock. The higher boost clock, combined with more shading units and a newer architecture, explains the large compute gap.

Where Each One Wins

The Intel Arc B390 wins decisively in every measurable compute and fill-rate category. Its FP32 throughput of 7.680 TFLOPS is over four times that of the 64EU Mobile, and its FP16 throughput of 15.36 TFLOPS similarly dwarfs the 3.584 TFLOPS of the 64EU Mobile. Pixel rate is 60.00 GPixel/s versus 28.00 GPixel/s, and texture rate is 120.0 GTexel/s versus 56.00 GTexel/s. The B390 also carries 12 RT cores, enabling hardware ray tracing workloads that the 64EU Mobile cannot accelerate. Its 2500 MHz boost clock is substantially higher, and its 3 nm process node indicates a more modern manufacturing technology.

The Intel Arc Graphics 64EU Mobile has no benchmark scores in the database and no nearest rivals, so its strengths are limited to lower power draw and an earlier release date. At 65 W TDP versus 80 W for the B390, the 64EU Mobile is the more power-efficient option, which matters in thin-and-light mobile designs where thermal headroom is constrained. Its 2023-12-13 release date also means it has been available for a longer period, and it lists HD Graphics-M as a predecessor, indicating an established product lineage. The 64EU Mobile's 512 shading units and 32 TMUs are sufficient for basic graphics tasks, but the data does not show any performance category where it exceeds the B390.

The Verdict

The data points clearly to the Intel Arc B390 as the stronger part in every performance metric recorded. Its 1482 3DMark Steel Nomad DX12 score, while not exceptional (9th percentile overall), is its only measured result and places it slightly ahead of several older NVIDIA discrete GPUs. The B390's 4.3x FP32 advantage, double the pixel rate, more than double the texture rate, and the presence of RT cores make it the obvious choice for any workload involving modern 3D rendering, ray tracing, or compute-heavy tasks. Its 3 nm process and 2500 MHz boost clock support this performance profile.

The Intel Arc Graphics 64EU Mobile is a lower-power integrated solution with a 65 W TDP, but it lacks recorded benchmarks, RT cores, and the newer architecture features of the B390. Its 1750 MHz boost clock and 512 shading units place it in a fundamentally different performance class. The 64EU Mobile's only advantages are lower power draw and earlier market availability, which are relevant for battery-conscious portable devices but not for demanding graphics work.

For users selecting between these two integrated GPUs, the Intel Arc B390 is the performance pick. It offers superior compute, higher fill rates, ray tracing hardware, and a more advanced DirectX 12 Ultimate feature set. The Intel Arc Graphics 64EU Mobile suits scenarios where power efficiency and proven availability outweigh raw performance, but the benchmark data provides no case where it outperforms the B390. The recorded measurements and specifications indicate a clear hierarchy: the B390 leads, the 64EU Mobile trails.
