Intel Arc Pro B370 vs NVIDIA GeForce RTX 4070 Mobile Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark comparisons between the Intel Arc Pro B370 and the NVIDIA GeForce RTX 4070 Mobile. The database lists benchmark scores only for the NVIDIA part, while the Intel part has an empty benchmark array. This means a direct numerical comparison of their performance in identical tests cannot be produced from the available measurements.

What can be established is the NVIDIA part's absolute performance levels. The GeForce RTX 4070 Mobile scores 109197 in Geekbench OpenCL and 108367 in Geekbench Vulkan. In Passmark tests, it delivers 19587 in G3D, 8399 in GPU compute, 763 in G2D, 223 in DirectX 9, 179 in DirectX 11, 116 in DirectX 10, and 85 in DirectX 12. Its average benchmark score is 27435.

The NVIDIA part sits at the 73rd percentile among all GPUs in the database. Its nearest rivals include the AMD Radeon RX 6700 XT with an average score of 27425 (0% delta), the NVIDIA GeForce RTX 3090 at 27565 (0.5% higher), the NVIDIA RTX PRO 4000 Blackwell at 27135 (1.1% lower), and the AMD Radeon Pro Vega 20 at 27839 (1.5% higher). These deltas are all within roughly 1.5% of each other, placing the RTX 4070 Mobile in a tightly contested performance band.

The Intel Arc Pro B370 has no benchmark scores recorded and no nearest rivals listed. Its percentile versus all GPUs is 50, which is the midpoint of the database distribution, but without actual scores, this cannot be validated against any measured workload. The absence of head-to-head results means the analysis must rely on architectural specifications and the NVIDIA part's standalone performance data.

Architecture Differences

The two GPUs come from fundamentally different design lineages. The Intel Arc Pro B370 uses the Panther Lake chip built on Intel's Xe3-LPG architecture, fabricated on a 3 nm process at Intel's own foundry. The NVIDIA GeForce RTX 4070 Mobile uses the AD106 chip based on Ada Lovelace architecture, built on a 5 nm process at TSMC.

Manufacturing details differ sharply. The NVIDIA GPU has 22,900 million transistors packed into a 188 mm² die, yielding a transistor density of 121.8 million transistors per square millimeter. The Intel part's transistor count and die size are listed as unknown in the database, so no density figure can be calculated for it.

The NVIDIA chip belongs to the GeForce 40 Mobile generation and succeeds the GeForce 30 Mobile. The Intel part is part of the Arc Graphics-WM (Panther Lake) generation and succeeds HD Graphics-WM. The NVIDIA GPU is also noted as having a successor, the GeForce 50 Mobile, while the Intel part has no successor listed.

Clock behavior reveals a significant difference in operating strategy. The Intel part runs a base clock of 300 MHz and boosts to 2400 MHz, an eightfold increase from base to boost. The NVIDIA part starts at 1395 MHz base and boosts to 1695 MHz, a much smaller relative jump. This suggests the Intel design relies heavily on boost behavior to reach its performance envelope, while the NVIDIA part operates closer to its maximum clock continuously.

Memory architecture is another major divergence. The Intel Arc Pro B370 uses system-shared memory, meaning it has no dedicated VRAM, no dedicated memory type, and no dedicated bus width. Its memory bandwidth is listed as system dependent. The NVIDIA GeForce RTX 4070 Mobile has 8 GB of GDDR6 memory on a 128-bit bus, delivering 256.0 GB/s of bandwidth. The memory clock is 2000 MHz with 16 Gbps effective transfer rate.

Compute resources are heavily skewed toward the NVIDIA part. The RTX 4070 Mobile has 4608 shading units, 144 texture mapping units, 48 render output units, 36 ray tracing cores, and 144 tensor cores. The Intel Arc Pro B370 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores, with no tensor cores listed. The NVIDIA GPU has 3.6 times the shading units, 3.6 times the TMUs, 2.4 times the ROPs, and 3.6 times the ray tracing cores.

Theoretical throughput figures follow the same pattern. The NVIDIA part achieves 15.62 TFLOPS FP32 and 15.62 TFLOPS FP16 with a 1:1 ratio. The Intel part delivers 6.144 TFLOPS FP32 and 12.29 TFLOPS FP16 with a 2:1 ratio. In FP32, the NVIDIA GPU is approximately 2.5 times faster. In FP16, the Intel part's 2:1 ratio gives it a relatively smaller deficit of about 27% versus the NVIDIA part's 1:1 FP16 throughput.

Pixel and texture rates also favor NVIDIA. The RTX 4070 Mobile produces 81.36 GPixel/s and 244.1 GTexel/s. The Intel part produces 48.00 GPixel/s and 96.00 GTexel/s. The NVIDIA GPU leads by roughly 1.7 times in pixel rate and 2.5 times in texture rate.

Power consumption differs substantially. The Intel Arc Pro B370 has a TDP of 25 W. The NVIDIA GeForce RTX 4070 Mobile has a TDP of 115 W, which is 4.6 times higher. Both are integrated into portable devices with no power connectors and no suggested PSU listed, and both use an IGP slot width. The NVIDIA part uses a PCIe 4.0 x8 bus interface, while the Intel part's bus interface is listed simply as IGP.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs for both are portable device dependent.

The Verdict

The data shows two GPUs designed for different purposes within portable systems. The NVIDIA GeForce RTX 4070 Mobile is a fully specified discrete-class mobile GPU with 4608 shading units, 8 GB of dedicated GDDR6 memory, 36 ray tracing cores, and 144 tensor cores. Its measured average benchmark score of 27435 places it at the 73rd percentile, directly competitive with desktop cards like the AMD Radeon RX 6700 XT and the NVIDIA GeForce RTX 3090, both within 0.5% of its score.

The Intel Arc Pro B370 presents a much smaller configuration. Its 1280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores are all substantially lower than the NVIDIA part. It uses system-shared memory, so its bandwidth is dependent on the host system rather than a dedicated VRAM pool. Its FP32 throughput of 6.144 TFLOPS is roughly 2.5 times lower than the NVIDIA part's 15.62 TFLOPS.

The power envelope tells the other side of the story. The Intel part draws 25 W, while the NVIDIA part draws 115 W. For systems where power is the binding constraint, the Intel part offers a much lighter load. The NVIDIA part consumes 4.6 times more power to deliver its substantially higher throughput.

The release timing also differs. The NVIDIA part launched on 2023-01-02, while the Intel part is dated 2026-01-26. The NVIDIA part has an established successor in the GeForce 50 Mobile. The Intel part has no successor listed.

There is no measured benchmark data for the Intel part, so its real-world performance cannot be quantified against the NVIDIA part. The only verifiable performance information belongs to the RTX 4070 Mobile, which holds a solid position among its nearest rivals.

Where Each One Wins

The NVIDIA GeForce RTX 4070 Mobile wins in every category where measured performance exists. Its benchmark scores across Geekbench OpenCL, Geekbench Vulkan, and the full Passmark suite establish it as a capable mobile GPU. Its average score of 27435 and 73rd percentile ranking place it among strong desktop and mobile parts.

The NVIDIA part's architectural advantages are clear. Its 4608 shading units, 144 TMUs, 48 ROPs, 36 ray tracing cores, and 144 tensor cores give it far more parallel compute capacity. Its 15.62 TFLOPS FP32 and 15.62 TFLOPS FP16 throughput, 81.36 GPixel/s pixel rate, and 244.1 GTexel/s texture rate all exceed the Intel part's corresponding figures. Its dedicated 8 GB GDDR6 memory with 256.0 GB/s bandwidth removes any dependency on system memory performance.

The Intel Arc Pro B370 wins only in power efficiency and system integration. Its 25 W TDP is less than a quarter of the NVIDIA part's 115 W. This makes it suitable for systems where power draw is strictly limited. Its 3 nm process node is also smaller than the NVIDIA part's 5 nm node, though the database does not record the Intel part's transistor count or die size to assess what that node advantage delivers. Its FP16 throughput of 12.29 TFLOPS is closer to the NVIDIA part's 15.62 TFLOPS than its FP32 figures, indicating the 2:1 FP16 ratio provides a relative strength there.

For systems with generous power budgets and a need for maximum compute, ray tracing, and memory bandwidth, the NVIDIA GeForce RTX 4070 Mobile is the supported choice. For systems where the 25 W power limit is the defining constraint, the Intel Arc Pro B370 is the only option that fits, though its performance cannot be quantified from the available data.
