Architecture Differences

The two GPUs come from fundamentally different design philosophies and process technologies. The Intel Arc Pro B370 is built on Intel's 3 nm process at Intel's own foundry, using the Panther Lake chip and Xe3-LPG architecture. It belongs to the Arc Graphics-WM (Panther Lake) generation, with its predecessor being HD Graphics-WM. The NVIDIA GeForce RTX 4080 Max-Q is built on TSMC's 5 nm process, using the AD104 chip with Ada Lovelace architecture. It belongs to the GeForce 40 Mobile generation, with its predecessor being GeForce 30 Mobile and its successor being GeForce 50 Mobile.

The transistor counts and die sizes differ substantially. The NVIDIA GPU contains 35,800 million transistors on a 294 mm² die, giving a transistor density of 121.8M per mm². The Intel GPU's transistor count and die size are listed as unknown, which prevents a direct comparison of manufacturing complexity.

The memory architecture is a major differentiator. The Intel Arc Pro B370 relies entirely on System Shared memory, with no dedicated VRAM, and its bandwidth is System Dependent. The NVIDIA GeForce RTX 4080 Max-Q uses 12 GB of GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of dedicated bandwidth. This means the NVIDIA part has guaranteed memory performance, while the Intel part's memory performance depends entirely on the host system's RAM configuration.

The execution resources show a large gap. The Intel GPU has 1280 shading units, 40 texture mapping units (TMUs), 20 raster operations pipelines (ROPs), and 10 ray tracing cores. The NVIDIA GPU has 7424 shading units, 232 TMUs, 80 ROPs, 58 ray tracing cores, and 232 tensor cores. The NVIDIA part also specifies tensor cores, which the Intel part does not list.

The compute rates reflect these resource differences. The Intel Arc Pro B370 delivers 6.144 TFLOPS of FP32 performance and 12.29 TFLOPS of FP16 performance at a 2:1 ratio. The NVIDIA GeForce RTX 4080 Max-Q delivers 20.04 TFLOPS of FP32 and 20.04 TFLOPS of FP16 at a 1:1 ratio. The NVIDIA part also achieves higher pixel and texture rates: 108.0 GPixel/s and 313.2 GTexel/s, compared to 48.00 GPixel/s and 96.00 GTexel/s on the Intel part.

Clock behavior also differs. The Intel GPU boosts from a 300 MHz base to 2400 MHz, a 2100 MHz range. The NVIDIA GPU has a 795 MHz base and 1350 MHz boost, a much smaller 555 MHz range. The Intel part's high boost clock helps it reach meaningful performance despite its modest TDP of 25 W, while the NVIDIA part operates within a 60 W envelope.

The bus interface also differs. The Intel Arc Pro B370 uses IGP as its bus interface, confirming its integrated nature. The NVIDIA GeForce RTX 4080 Max-Q uses PCIe 4.0 x16, indicating a discrete connection to the system.

Head-to-Head Benchmarks

The recorded database contains no head-to-head benchmark entries for these two GPUs, and neither part has individual benchmark scores listed. This means quantitative performance comparisons must rely on the specification data provided.

The clearest advantage for the NVIDIA GeForce RTX 4080 Max-Q appears in raw compute throughput. Its FP32 performance of 20.04 TFLOPS is approximately 3.26 times the Intel Arc Pro B370's 6.144 TFLOPS. In FP16, the NVIDIA part's 20.04 TFLOPS at 1:1 ratio represents a 1.63 times advantage over the Intel part's 12.29 TFLOPS at 2:1 ratio. The 2:1 ratio on the Intel part means FP16 throughput is achieved through a packed operation, while the NVIDIA part maintains full-rate FP16.

The pixel rate comparison shows the NVIDIA GPU at 108.0 GPixel/s versus 48.00 GPixel/s on the Intel GPU, a 2.25 times advantage. The texture rate comparison shows 313.2 GTexel/s versus 96.00 GTexel/s, a 3.26 times advantage for NVIDIA. These ratios are consistent with the shading unit and TMU counts: the NVIDIA part has 5.8 times more shading units and 5.8 times more TMUs.

The ray tracing hardware also favors NVIDIA. The RTX 4080 Max-Q has 58 ray tracing cores versus 10 on the Arc Pro B370. The NVIDIA part additionally includes 232 tensor cores, which the Intel part does not list.

Memory bandwidth is another decisive area. The NVIDIA GPU's 432.0 GB/s of dedicated GDDR6 bandwidth cannot be compared numerically to the Intel part's System Dependent bandwidth, but the architectural difference is clear: one has fixed, high bandwidth, the other depends on the host's shared memory configuration.

Clock speeds present a mixed picture. The Intel Arc Pro B370 has a higher boost clock at 2400 MHz versus 1350 MHz on the NVIDIA part, a 1050 MHz difference. However, the NVIDIA part's base clock of 795 MHz is 495 MHz higher than the Intel part's 300 MHz base. The Intel part's higher boost clock partially compensates for its fewer execution units, but the raw resource gap remains substantial.

The TDP difference of 35 W (25 W versus 60 W) indicates the NVIDIA part is allowed more power to feed its larger array of execution units. The performance per watt cannot be calculated from the provided data, but the absolute performance advantage clearly belongs to NVIDIA.

The Verdict

Based strictly on the recorded data, the NVIDIA GeForce RTX 4080 Max-Q is the higher-performing GPU in nearly every measurable specification. Its FP32 throughput is 3.26 times higher, its pixel rate is 2.25 times higher, its texture rate is 3.26 times higher, and it has 5.8 times more ray tracing cores. It also has dedicated 12 GB GDDR6 memory with 432.0 GB/s bandwidth, while the Intel part relies on System Shared memory.

The Intel Arc Pro B370 does hold advantages in certain areas. Its boost clock of 2400 MHz is significantly higher than the NVIDIA part's 1350 MHz. Its TDP of 25 W is less than half of the NVIDIA part's 60 W. It is built on a newer 3 nm process versus 5 nm, and it is an integrated GPU, which means it requires no separate card slot or power connectors beyond what the system provides.

The production timelines differ: the Intel part was released on January 26, 2026, while the NVIDIA part was released on January 2, 2023. The NVIDIA part has an active production status and lists a successor (GeForce 50 Mobile), while the Intel part also lists an active production status with no successor.

The data does not include benchmark scores, percentile rankings, or rival comparisons for either GPU. The percentileVsAllGpus field is 50 for both, and avgBenchmarkScore is 0 for both, indicating no recorded performance measurements. Without benchmark data, the specification analysis is the only available basis for comparison.

The verdict from the data is clear: the NVIDIA GeForce RTX 4080 Max-Q is designed for substantially higher absolute performance, while the Intel Arc Pro B370 is designed for integration and low power consumption. The choice between them depends on whether the use case demands maximum throughput or minimal power draw within an integrated form factor.
