Architecture Differences

The Intel Arc B370 is built on Intel's Xe3-LPG architecture, part of the Panther Lake chip, and represents the Arc Graphics-M (Panther Lake) generation. It uses a 3 nm process node fabricated by Intel itself. The NVIDIA GeForce RTX 4070 Max-Q belongs to the Ada Lovelace architecture, built on the AD106 chip, and is part of the GeForce 40 Mobile generation. This GPU uses a 5 nm process from TSMC.

The Intel chip integrates its graphics directly into the Panther Lake processor, with an IGP bus interface. The NVIDIA GPU connects via PCIe 4.0 x8, indicating a discrete-class solution despite its IGP slot width designation. The transistor counts reflect this difference: the Intel die size and transistor count are unknown, while the NVIDIA chip contains 22,900 million transistors on a 188 mm² die, achieving a transistor density of 121.8M per mm².

Feature sets diverge significantly. The Intel Arc B370 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 RT cores. The NVIDIA GeForce RTX 4070 Max-Q packs 4608 shading units, 144 TMUs, 48 ROPs, 36 RT cores, and adds 144 tensor cores, which the Intel GPU lacks entirely. The NVIDIA GPU supports FP16 at a 1:1 ratio with FP32, while the Intel GPU uses a 2:1 ratio, achieving 12.29 TFLOPS FP16 versus 6.144 TFLOPS FP32.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA GPU's predecessor is GeForce 30 Mobile, and its successor is GeForce 50 Mobile. The Intel Arc B370 has no listed predecessor or successor. Production status for both is Active, with the Intel part releasing on January 26, 2026, and the NVIDIA part on January 2, 2023.

Head-to-Head Benchmarks

The database contains only one benchmark result for these two GPUs: a 3DMark Steel Nomad DX12 score of 1184 for the Intel Arc B370. No benchmark scores are recorded for the NVIDIA GeForce RTX 4070 Max-Q, and no head-to-head benchmark results exist in the database.

The Intel Arc B370's single score places it in the 5th percentile of all GPUs. Its nearest rivals in the database provide context: the ATI Mobility Radeon HD 5570 scores 1186 (a delta of -0.2% for the Intel GPU), the ATI Radeon HD 5770 scores 1190 (delta -0.5%), the AMD Radeon HD 7650M scores 1192 (delta -0.7%), and the AMD FirePro M2000 scores 1168 (delta +1.4%). The Intel Arc B370 sits essentially at parity with these older mobile and desktop parts, within a range of roughly 2% across all four rivals.

The NVIDIA GeForce RTX 4070 Max-Q has an average benchmark score of 0 in the database, placing it in the 50th percentile by default, but with no recorded measurements to substantiate performance claims. The data cannot confirm any performance advantage for the NVIDIA GPU in specific workloads. The specification sheet indicates higher theoretical throughput, but benchmark verification is absent.

The absence of head-to-head results means direct comparison rests on architectural specifications rather than measured outcomes. The Intel GPU's recorded score of 1184 in Steel Nomad DX12, a modern DirectX 12 test, shows it operating at a modest level consistent with its 5th percentile ranking. The NVIDIA GPU's unspecified performance leaves its percentile ranking of 50 as an unverified placeholder.

Specification Differences

The two GPUs differ across nearly every measured specification. The Intel Arc B370 uses a 3 nm Intel process; the NVIDIA GeForce RTX 4070 Max-Q uses a 5 nm TSMC process. The NVIDIA chip has a known transistor count of 22,900 million and die size of 188 mm², while Intel's transistor count and die size are unknown.

Clock speeds show a significant gap. The Intel GPU has a base clock of 300 MHz and boost clock of 2400 MHz. The NVIDIA GPU has a base clock of 735 MHz and boost clock of 1230 MHz. The Intel part's boost clock is nearly double the NVIDIA part's boost clock, though the NVIDIA part's higher base clock suggests different power and thermal characteristics.

Memory configurations are fundamentally different. The Intel Arc B370 uses system shared memory with a system-dependent bus width and bandwidth. The NVIDIA GeForce RTX 4070 Max-Q has 8 GB of GDDR6 memory on a 128-bit bus with 256.0 GB/s bandwidth and a memory clock of 2000 MHz (16 Gbps effective).

Compute resources differ substantially. The Intel GPU has 1280 shading units, 40 TMUs, 20 ROPs, and 10 RT cores. The NVIDIA GPU has 4608 shading units, 144 TMUs, 48 ROPs, 36 RT cores, and 144 tensor cores. Pixel rate for Intel is 48.00 GPixel/s versus 59.04 GPixel/s for NVIDIA. Texture rate is 96.00 GTexel/s for Intel versus 177.1 GTexel/s for NVIDIA. FP32 throughput is 6.144 TFLOPS for Intel versus 11.34 TFLOPS for NVIDIA. FP16 throughput is 12.29 TFLOPS (2:1) for Intel versus 11.34 TFLOPS (1:1) for NVIDIA.

Power draw differs: 25 W for Intel, 35 W for NVIDIA. Both are IGP slot width with no power connectors. The bus interface differs: IGP for Intel, PCIe 4.0 x8 for NVIDIA. Both have portable device dependent display outputs. API support is identical: DirectX 12 Ultimate (12_2), OpenGL 4.6, Vulkan 1.4.

Release dates differ by roughly three years: January 26, 2026 for Intel, January 2, 2023 for NVIDIA. The NVIDIA GPU has a predecessor (GeForce 30 Mobile) and successor (GeForce 50 Mobile) listed; the Intel GPU has neither.

The Verdict

The data indicates two GPUs at opposite ends of the mobile graphics spectrum. The Intel Arc B370, with its 5th percentile ranking and a single 3DMark Steel Nomad DX12 score of 1184, sits alongside decade-old parts like the ATI Mobility Radeon HD 5570 and AMD Radeon HD 7650M. Its 25 W TDP, system shared memory, and IGP bus interface position it as a low-power integrated solution for basic graphics workloads.

The NVIDIA GeForce RTX 4070 Max-Q presents a different profile entirely. Its specifications describe a much more capable part: 4608 shading units, 36 RT cores, 144 tensor cores, 8 GB of dedicated GDDR6 memory with 256.0 GB/s bandwidth, and 11.34 TFLOPS FP32 throughput. The 35 W TDP and PCIe 4.0 x8 interface suggest a discrete-class GPU designed for higher performance within a mobile power envelope. The 50th percentile ranking, while lacking benchmark verification, aligns with a mid-range position among all GPUs.

The architectural gap is stark. The NVIDIA GPU has roughly 3.6 times the shading units, 3.6 times the RT cores, 3.6 times the TMUs, and 2.4 times the ROPs of the Intel GPU. It has 144 tensor cores where Intel has none. Its FP32 throughput is 84% higher. Its memory bandwidth is a dedicated 256.0 GB/s versus a system-dependent figure for Intel. The NVIDIA GPU also benefits from a known process with 22,900 million transistors, while Intel's die details remain undisclosed.

The Intel GPU's higher boost clock of 2400 MHz versus 1230 MHz for NVIDIA does not compensate for the massive resource deficit. The Intel part's FP16 advantage of 12.29 TFLOPS versus 11.34 TFLOPS reflects its 2:1 FP16 ratio, but this applies only to workloads that can exploit it.

The recorded benchmark data favors no one: the Intel GPU has one measured score showing modest performance, and the NVIDIA GPU has no measured scores at all. However, the specification sheet tells a clear story. For applications requiring dedicated graphics memory, tensor core acceleration, and high compute throughput, the NVIDIA GeForce RTX 4070 Max-Q is the only option with the necessary resources. For ultra-low-power integrated graphics in a portable device, the Intel Arc B370 fits that niche with its 25 W TDP and system shared memory.

The database's percentile data reinforces this: the Intel GPU at the 5th percentile competes with legacy hardware, while the NVIDIA GPU's unverified 50th percentile suggests a mainstream position. Users seeking discrete-class mobile graphics performance should look to the NVIDIA part based on its specifications. Users constrained to an integrated solution with minimal power draw will find the Intel part's capabilities defined by its single benchmark score and low resource counts. The data does not support treating these as comparable options; they serve different segments of the mobile GPU market.
