The Arc B770 does have a predecessor, the Alchemist architecture, while the RTX 4060 Mobile's predecessor is the GeForce 30 Mobile series.

# Architecture Differences

The Arc B770 uses the BMG-G31 chip built on the Xe2-HPG architecture, part of the Battlemage generation under the Arc 7 product line. The RTX 4060 Mobile uses the AD107 chip on the Ada Lovelace architecture, part of the GeForce 40 Mobile series. Both are manufactured on a 5 nm process at TSMC, but the physical implementations differ sharply. The Arc B770 die measures 368 mm², while the RTX 4060 Mobile die measures 159 mm², making the Intel chip 131.4% larger. The NVIDIA die packs 18,900 million transistors, and its density reaches 118.9 million per square millimeter.

Clock behavior differs between the two. The Arc B770 runs at a 2100 MHz base and 2400 MHz boost, while the RTX 4060 Mobile runs at 1545 MHz base and 1890 MHz boost. Both use GDDR6 memory at 2000 MHz with 16 Gbps effective transfer, but the bus widths differ: 256-bit for Intel, 128-bit for NVIDIA. The memory subsystem results in 512.0 GB/s for the Arc B770 and 256.0 GB/s for the RTX 4060 Mobile.

The compute architectures diverge in FP16 handling. The Arc B770 processes FP16 at a 2:1 ratio relative to FP32, reaching 39.32 TFLOPS. The RTX 4060 Mobile processes FP16 at 1:1, matching its FP32 rate of 11.61 TFLOPS. This suggests the Intel architecture is designed for workloads that benefit from reduced-precision throughput, while the NVIDIA part prioritizes consistent precision across formats.

The RTX 4060 Mobile includes 96 tensor cores, which are absent from the Arc B770 specification list. Ray tracing hardware exists on both, with 32 RT cores on the Intel card and 24 on the NVIDIA part. The API support is identical: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ significantly. The Arc B770 provides 1x HDMI 2.1a and 3x DisplayPort 2.1, while the RTX 4060 Mobile lists "Portable Device Dependent" outputs, reflecting its mobile integration. The bus interface also differs: PCIe 4.0 x16 for the Arc B770 versus PCIe 4.0 x8 for the RTX 4060 Mobile.

# The Verdict

The recorded data presents a clear split between the two GPUs. The RTX 4060 Mobile has a fully documented benchmark profile with an average score of 22,729 and a 67th percentile ranking. Its nearest rivals cluster within 1.3 percentage points, showing that it performs in a tightly competitive band. The Arc B770 has no benchmark scores, a 50th percentile ranking, and no listed rivals, meaning its actual performance cannot be validated against any GPU in the database.

For users who require measured performance data, the RTX 4060 Mobile is the only choice with evidence. It delivers documented results across nine tests, including strong Geekbench Vulkan and OpenCL scores above 89,000 and a PassMark G3D score of 17,469. Its efficiency profile is also favorable for mobile integration: 115 W TDP, no power connectors, and an IGP form factor. The Arc B770, by contrast, demands 225 W, a dual-slot cooler, and external power connectors, making it unsuitable for the same portable use case.

The Arc B770 offers specifications that suggest higher raw capacity. Its FP32 throughput of 19.66 TFLOPS is 69.3% higher than the RTX 4060 Mobile's 11.61 TFLOPS. Its memory bandwidth of 512.0 GB/s doubles the NVIDIA part. Its pixel rate of 307.2 GPixel/s and texture rate of 614.4 GTexel/s are both 238.6% higher. These numbers indicate a GPU designed for high-throughput desktop workloads, but without benchmark scores, the database cannot confirm how these specifications translate into application performance.

The RTX 4060 Mobile's tensor cores provide a feature the Arc B770 does not list, which matters for workloads that use tensor operations. The NVIDIA part also benefits from an active production status and a documented successor, while the Arc B770 lists neither. The architecture differences also show the RTX 4060 Mobile using a 159 mm² die versus 368 mm² for the Arc B770, meaning the NVIDIA part achieves its results with a much smaller physical footprint.

The verdict from the data is straightforward. The RTX 4060 Mobile is the validated performer with measurable results, a clear competitive position among its rivals, and a power envelope suited to portable systems. The Arc B770 is a specification-heavy desktop card with higher theoretical throughput, more memory, and wider bandwidth, but the absence of benchmark data leaves its actual performance unverified. Users who need confirmed results should rely on the RTX 4060 Mobile. Users who prioritize raw specifications and have the power budget for a 225 W dual-slot card may consider the Arc B770, but the database offers no evidence of its real-world capability.
