Intel Arc B390 vs NVIDIA GeForce RTX 4060 Mobile Comparison

The Verdict

The recorded data presents a stark contrast between the Intel Arc B390 and the NVIDIA GeForce RTX 4060 Mobile. The Arc B390, an integrated graphics processor from the Panther Lake generation, posts a single 3DMark Steel Nomad DX12 score of 1482, placing it in the 9th percentile of all GPUs. Its nearest rivals are legacy NVIDIA parts like the GeForce GT 520MX and GeForce 800M, with delta percentages of 1.3% and 1.5% respectively. This indicates the Arc B390 operates in a performance tier that is fundamentally different from the RTX 4060 Mobile.

The RTX 4060 Mobile, by contrast, achieves an average benchmark score of 22729 across nine different tests, including OpenCL, Vulkan, and multiple Passmark DirectX variants. It sits in the 67th percentile of all GPUs, with its nearest rival being the desktop NVIDIA GeForce RTX 2080, which it trails by only 0.7%. The data confirms that the RTX 4060 Mobile is a discrete-class solution that outperforms the Arc B390 by an enormous margin in raw compute and graphics throughput. The Intel part is suitable only for the lightest graphical workloads, whereas the NVIDIA part is positioned for modern gaming and content creation.

The data suggests no realistic competition between these two products. The RTX 4060 Mobile is the only viable choice for any task requiring significant GPU acceleration. The Arc B390, based on its sub-1500 score, is confined to basic display output and minimal 2D acceleration. There is no overlap in their intended usage scenarios as defined by benchmark results.

Head-to-Head Benchmarks

Direct head-to-head benchmark entries are absent from the database, so comparisons must rely on the aggregate scores and the relative positioning against common rivals. The Arc B390's sole benchmark, 3DMark Steel Nomad DX12, produced a score of 1482. The RTX 4060 Mobile's Passmark G3D score alone is 17469, which is over eleven times higher than the Arc B390's total output. This single comparison highlights the gulf in graphics processing capability.

The RTX 4060 Mobile's Passmark DirectX 11 score of 157 and DirectX 12 score of 73 are low-level API performance indicators, yet they dwarf the Arc B390's only recorded result. The Intel part's nearest rival, the NVIDIA GeForce GT 520MX, scores 1463, which is merely 1.3% lower. This places the Arc B390 in the same performance class as GPUs from over a decade ago. The RTX 4060 Mobile, conversely, sits within 1.3% of the Intel Arc B580 and ahead of the AMD Radeon RX 7700 XT by 0.8%.

In compute workloads, the RTX 4060 Mobile delivers a Passmark GPU Compute score of 6816 and a Geekbench OpenCL score of 89420. The Arc B390 has no equivalent compute benchmark recorded. The FP32 throughput figures from the specification data reinforce the divide: the RTX 4060 Mobile is rated for 11.61 TFLOPS, while the Arc B390 is rated for 7.680 TFLOPS. Even in raw mathematical throughput, the NVIDIA part holds a 51% advantage. The texture rate for the RTX 4060 Mobile is 181.4 GTexel/s versus 120.0 GTexel/s for the Arc B390, a 51.2% difference. Pixel rate follows the same pattern, with 90.72 GPixel/s for NVIDIA and 60.00 GPixel/s for Intel.

A: The RTX 4060 Mobile uses 8 GB of GDDR6 memory on a 128-bit bus with 256.0 GB/s of bandwidth. The Arc B390 uses system shared memory with no dedicated VRAM, and its bandwidth is listed as system dependent.

Specification Differences

The two GPUs differ across nearly every measurable specification. The RTX 4060 Mobile uses the AD107 chip built on a 5 nm process by TSMC, with 18,900 million transistors on a 159 mm² die and a transistor density of 118.9M per mm². The Arc B390 uses the Panther Lake chip built on a 3 nm process by Intel, with transistor count, die size, and density all listed as unknown.

Clock speeds diverge significantly. The Arc B390 has a base clock of 300 MHz and a boost clock of 2500 MHz. The RTX 4060 Mobile has a base clock of 1545 MHz and a boost clock of 1890 MHz. The Intel part boosts higher but starts much lower, while the NVIDIA part maintains a higher floor. The RTX 4060 Mobile also has a dedicated memory clock of 2000 MHz with 16 Gbps effective speed, whereas the Arc B390 relies on system shared memory with no dedicated clock.

The shading units, texture mapping units, and raster operation units all favor NVIDIA. The RTX 4060 Mobile has 3072 shading units, 96 TMUs, and 48 ROPs. The Arc B390 has 1536 shading units, 48 TMUs, and 24 ROPs. Each NVIDIA count is exactly double the Intel count. Ray tracing cores follow the same pattern: 24 for NVIDIA versus 12 for Intel. The RTX 4060 Mobile also includes 96 tensor cores, while the Arc B390 lists none.

The RTX 4060 Mobile draws 115 W compared to 80 W for the Arc B390. Both are listed as IGP slot width with no power connectors. The bus interface differs: the RTX 4060 Mobile uses PCIe 4.0 x8, while the Arc B390 uses IGP. Display outputs for both are listed as portable device dependent. The RTX 4060 Mobile has a release date of 2023-01-02, whereas the Arc B390 has a release date of 2026-01-26.

Architecture Differences

The Intel Arc B390 is built on the Xe3-LPG architecture and belongs to the Arc Graphics-M (Panther Lake) generation. It uses a 3 nm process node fabricated by Intel. The RTX 4060 Mobile uses the Ada Lovelace architecture from the GeForce 40 Mobile generation, fabricated on a 5 nm process by TSMC.

The memory architecture represents a fundamental difference. The Arc B390 has no dedicated VRAM; its memory size, type, and bus width are all listed as system shared. Memory bandwidth is system dependent, meaning performance varies with the host platform's memory configuration. The RTX 4060 Mobile has dedicated 8 GB GDDR6 memory on a 128-bit bus with a fixed 256.0 GB/s bandwidth.

Compute capabilities differ in structure. The Arc B390 supports FP16 at a 2:1 ratio, delivering 15.36 TFLOPS, while FP32 is rated at 7.680 TFLOPS. The RTX 4060 Mobile supports FP16 at a 1:1 ratio, delivering 11.61 TFLOPS for both FP16 and FP32. This means the Intel part has higher peak FP16 throughput but lower FP32 throughput, while the NVIDIA part maintains consistent performance across both formats.

The RTX 4060 Mobile includes 96 tensor cores for AI acceleration, a feature absent from the Arc B390's specification list. Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 4060 Mobile has a predecessor, GeForce 30 Mobile, and a successor, GeForce 50 Mobile, while the Arc B390 lists no predecessor or successor.

Where Each One Wins

The RTX 4060 Mobile wins in every recorded benchmark category. Its average benchmark score of 22729 versus 1482 for the Arc B390 means it dominates in DirectX 10, 11, and 12 workloads, as well as OpenCL, Vulkan, and compute tasks. The Passmark G3D score of 17469 for the NVIDIA part shows it can handle substantial 3D rendering workloads, whereas the Arc B390's single 3DMark score of 1482 indicates minimal 3D capability.

For gaming, the data clearly favors the RTX 4060 Mobile. Its nearest rival is the desktop RTX 2080, which is only 0.7% faster, placing the mobile part in the upper tier of gaming GPUs. The Arc B390's nearest rivals are the GT 520MX and GeForce 800M, which are not capable of modern gaming at playable settings. The RTX 4060 Mobile's 8 GB GDDR6 memory with 256.0 GB/s bandwidth provides adequate memory resources for modern game assets, while the Arc B390's shared memory setup cannot guarantee consistent performance.

For compute and AI workloads, the RTX 4060 Mobile wins decisively. Its 96 tensor cores and 11.61 TFLOPS FP32 throughput support machine learning and content creation tasks. The Passmark GPU Compute score of 6816 confirms this capability. The Arc B390 has no tensor cores and lower FP32 throughput, limiting its usefulness in these applications.

The Arc B390 has no category where it outperforms the RTX 4060 Mobile based on recorded data. Its only advantages are a lower power draw of 80 W versus 115 W and a smaller process node of 3 nm versus 5 nm. These are efficiency and manufacturing attributes, not performance wins. The integrated nature of the Arc B390 means it requires no separate power connectors, but its performance ceiling is so low that it only suits basic display tasks or legacy applications. The RTX 4060 Mobile, despite higher power consumption, delivers over 15 times the average benchmark score and remains the only viable option for any demanding graphical work.
