Intel Arc Pro B70 vs NVIDIA RTX 3000 Mobile Ada Generation Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark results for the Intel Arc Pro B70 and the NVIDIA RTX 3000 Mobile Ada Generation. Both entries list empty benchmark arrays, zero wins for each side, and no nearest rival comparisons. Consequently, the analysis below relies entirely on the specification sheets and the computed performance metrics recorded for each product, rather than on measured application tests.

The Intel Arc Pro B70 delivers a peak FP32 throughput of 22.94 TFLOPS, which is 46.8% higher than the 15.62 TFLOPS of the RTX 3000 Mobile Ada. This is the single largest arithmetic advantage in the comparison, and it stems from the Intel part's higher boost clock of 2800 MHz versus 1695 MHz, combined with 4096 shading units against 4608 on the NVIDIA side. Although NVIDIA fields more shading units, the Intel architecture compensates with a substantially higher operating frequency, resulting in a clear theoretical compute lead.

In FP16 workloads, the divergence becomes more pronounced. The Intel Arc Pro B70 records 45.88 TFLOPS using a 2:1 rate, while the RTX 3000 Mobile Ada achieves only 15.62 TFLOPS at a 1:1 rate. That represents a 193.7% advantage for Intel in half-precision throughput. This gap is critical for machine learning inference and certain scientific workloads where FP16 operations dominate, though the NVIDIA part includes dedicated tensor cores that the Intel specification sheet does not list, which may alter real-world AI performance.

Memory bandwidth also favors Intel decisively. The Arc Pro B70 has a 256-bit bus with 32 GB of GDDR6 memory, yielding 608.0 GB/s, whereas the RTX 3000 Mobile Ada uses a 128-bit bus with 8 GB, yielding 256.0 GB/s. Intel's bandwidth advantage is 137.5%, which directly supports its higher texture and pixel rates. The Intel card processes 716.8 GTexel/s and 358.4 GPixel/s, compared with 244.1 GTexel/s and 81.36 GPixel/s for the NVIDIA part, representing 193.7% and 340.5% advantages, respectively. The pixel rate gap is especially large because the Intel card has 128 ROPs versus 48 ROPs on the RTX 3000 Mobile Ada.

The RTX 3000 Mobile Ada does hold ground in ray tracing resources. It lists 36 RT cores against 32 on the Intel Arc Pro B70, an 11.1% advantage in dedicated ray tracing hardware count. The NVIDIA part also includes 144 tensor cores, which are absent from the Intel specification entirely. These features do not appear in the raw FP32 or FP16 figures but are relevant for workloads that specifically use ray tracing acceleration or tensor-core-optimized libraries.

Both products share the same API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Neither has recorded benchmark scores, and both sit at the 50th percentile among all GPUs in the database, indicating that the database currently lacks sufficient measured data to differentiate them on real-world application performance.

The Verdict

The data indicates that the Intel Arc Pro B70 is the stronger candidate for workloads that prioritize raw rasterization throughput, memory capacity, and memory bandwidth. Its 22.94 TFLOPS FP32, 608.0 GB/s bandwidth, and 32 GB capacity place it far ahead of the RTX 3000 Mobile Ada in traditional GPU compute metrics. The pixel rate advantage of 340.5% and texture rate advantage of 193.7% suggest that fill-rate-limited scenes, such as high-resolution rendering with heavy overdraw, would favor the Intel part substantially.

The NVIDIA RTX 3000 Mobile Ada, by contrast, is positioned for mobile integration with a 115 W TDP, no external power connectors, and an IGP form factor. Its 36 RT cores and 144 tensor cores provide dedicated hardware that the Intel specification does not enumerate. The NVIDIA part also has a lower die size of 188 mm² versus 368 mm² for Intel, and a higher transistor density of 121.8M per mm² versus an unknown figure for Intel, though the Intel part uses more total die area.

Users who require a desktop workstation card with large memory capacity for datasets that exceed 8 GB, or who need maximum FP32 and FP16 throughput, should select the Intel Arc Pro B70 based on the recorded specifications. Users who need a low-power, mobile-integrated GPU with dedicated ray tracing and tensor hardware should select the NVIDIA RTX 3000 Mobile Ada, provided that the 8 GB memory and 256.0 GB/s bandwidth are sufficient for their workloads.

Architecture Differences

The Intel Arc Pro B70 uses the Xe2-HPG architecture on the BMG-G31 chip, part of the Battlemage (Pro Series) generation. The NVIDIA RTX 3000 Mobile Ada uses the Ada Lovelace architecture on the AD106 chip, part of the Ada-MW generation with a GeForce 30-series designation. Both are fabricated on a 5 nm process at TSMC, but they diverge significantly in die size: Intel uses 368 mm², while NVIDIA uses 188 mm². NVIDIA's chip integrates 22,900 million transistors with a density of 121.8M per mm², whereas Intel's transistor count is listed as unknown.

In terms of compute resources, the Intel part has 256 TMUs and 128 ROPs, while the NVIDIA part has 144 TMUs and 48 ROPs. The Intel card has 32 RT cores, and the NVIDIA card has 36 RT cores. The NVIDIA card additionally lists 144 tensor cores, which are not present in the Intel specification. The Intel card's memory subsystem is wider (256-bit versus 128-bit) and operates at a higher effective speed (19 Gbps versus 16 Gbps), producing 608.0 GB/s versus 256.0 GB/s.

The Intel Arc Pro B70 is a dual-slot desktop card with a 267 mm length, 110 mm height, and 39 mm width, using a PCIe 5.0 x16 interface and requiring a 230 W TDP with a single 8-pin connector. The NVIDIA RTX 3000 Mobile Ada is an IGP with no listed physical dimensions, no power connectors, a 115 W TDP, and a PCIe 4.0 x16 interface. The Intel card offers fixed display outputs (1x HDMI 2.1 and 3x DisplayPort 2.1), while the NVIDIA part's outputs are portable-device-dependent.

The release dates differ materially: Intel's card is dated 2026-03-25, while NVIDIA's is dated 2023-03-20. The NVIDIA part has a predecessor (Ampere-MW) and successor (Blackwell-MW) recorded, while the Intel part lists none.

Where Each One Wins

Based on the specification data, the Intel Arc Pro B70 wins in all raw throughput categories. It delivers 46.8% higher FP32 performance, 193.7% higher FP16 performance, 193.7% higher texture rate, and 340.5% higher pixel rate compared with the NVIDIA RTX 3000 Mobile Ada. The Intel card also offers four times the memory capacity (32 GB versus 8 GB) and 137.5% higher bandwidth. These advantages make it the appropriate choice for desktop workloads involving large datasets, high-resolution rendering, and compute-heavy FP16 tasks where the 2:1 rate is usable.

The NVIDIA RTX 3000 Mobile Ada wins in resource efficiency and specialized hardware count. Its 115 W TDP is exactly half of Intel's 230 W TDP, making it suitable for mobile integration where power budgets are constrained. It has 144 tensor cores and 36 RT cores, which the Intel specification does not match either in count (32 RT cores) or presence (no tensor cores listed). The NVIDIA part also uses a smaller die (188 mm² versus 368 mm²) and has a higher transistor density (121.8M per mm² versus unknown for Intel), indicating a more compact design.

The NVIDIA part is the only one with an active production status, while the Intel part's production status is not recorded. The NVIDIA product has a recorded predecessor and successor, suggesting an established product lifecycle. The Intel card is newer by release date (2026-03-25 versus 2023-03-20) and has a launch MSRP of 949 USD, while NVIDIA's mobile part has no recorded MSRP.

For workloads that require maximum fill rate, large frame buffers, or FP16 throughput, the Intel Arc Pro B70 is the clear specification-based winner. For workloads that depend on tensor-core acceleration, ray tracing core count, or minimal power draw in a mobile form factor, the NVIDIA RTX 3000 Mobile Ada holds the advantage. Neither product has recorded benchmark scores in the database, so these conclusions rest solely on the documented hardware specifications and computed theoretical rates.
