Intel Arc Pro B370 vs NVIDIA GeForce RTX 4080 Mobile Comparison

Head-to-Head Benchmarks

The recorded data contains benchmark results for the NVIDIA GeForce RTX 4080 Mobile, while the Intel Arc Pro B370 has no benchmark scores in the database. This absence of measured results for the Intel part means a direct score-by-score comparison is not possible from the available information. What the data does show is the RTX 4080 Mobile’s performance profile across nine separate tests, and how that profile positions it relative to other GPUs in the database.

The RTX 4080 Mobile delivers its strongest measured result in the Geekbench OpenCL test with a score of 159575. Its Geekbench Vulkan result is close behind at 145807, indicating strong compute and graphics API performance. In the Passmark suite, the GPU scores 24926 in the G3D test, which is the primary gaming-oriented metric. The Passmark GPU Compute score is 11191, roughly 45% of the G3D result, which shows a notable gap between rasterization throughput and general compute workloads. The DirectX API-specific tests show 286 in DirectX 9, 244 in DirectX 11, 157 in DirectX 10, and 96 in DirectX 12. The G2D score of 929 reflects 2D desktop performance that is far lower than any 3D result, as expected for a discrete mobile GPU.

Because the Intel Arc Pro B370 has zero recorded benchmarks and an average benchmark score of 0, the head-to-head comparison defaults entirely to the NVIDIA part’s measured results. The wins count in the database is 0 for Intel and 0 for NVIDIA, indicating that no head-to-head benchmark entries exist for these two products. The RTX 4080 Mobile’s average benchmark score across all tests is 38135, which places it at the 81st percentile among all GPUs in the database. The Intel part sits at the 50th percentile, but that value is derived from its hardware specifications rather than any measured workload data.

The nearest rivals for the RTX 4080 Mobile provide context for its average score. The NVIDIA GeForce MX570 has an average score of 38299, which is 0.4% higher than the RTX 4080 Mobile. The NVIDIA GeForce RTX 5080 Mobile scores 38349, 0.6% higher. The NVIDIA GeForce RTX 4070 scores 37648, which is 1.3% lower. The NVIDIA Tesla P4 scores 37628, also 1.3% lower. These deltas are small, all within 1.3 percentage points, indicating that the RTX 4080 Mobile sits in a tightly clustered performance band with these four other GPUs. The Intel Arc Pro B370 has no nearest rivals listed in the database, so no comparable positioning exists for it.

Where Each One Wins

The RTX 4080 Mobile wins in every category where data exists. It has measured scores in compute, graphics, and API-specific tests, all of which are substantial. The Intel Arc Pro B370 has no wins because no benchmarks were recorded for it. The database shows 0 wins for Intel and 0 wins for NVIDIA, but that count reflects the absence of head-to-head tests rather than a tie in performance.

For use cases that rely on raw compute throughput, the RTX 4080 Mobile’s Geekbench OpenCL score of 159575 and Vulkan score of 145807 indicate strong suitability for compute-heavy workloads such as rendering, simulation, or data processing. The Passmark GPU Compute score of 11191 reinforces this, though it is lower than the G3D score, suggesting the GPU is more optimized for graphics than for generic compute tasks. For gaming, the Passmark G3D score of 24926 and the DirectX 11 score of 244 indicate solid performance in older API titles, while the DirectX 12 score of 96 is notably weaker, which could affect modern games that rely on DX12 features.

The Intel Arc Pro B370, with its 1280 shading units, 40 texture mapping units, and 20 raster operation units, has a theoretical pixel rate of 48.00 GPixel/s and a texture rate of 96.00 GTexel/s. Its FP32 throughput is 6.144 TFLOPS. These specifications suggest a low-power integrated GPU, but without benchmark scores, the database cannot confirm how those specifications translate into real-world performance. The RTX 4080 Mobile, by contrast, has 7424 shading units, 232 TMUs, 80 ROPs, and FP32 throughput of 24.72 TFLOPS, which is approximately four times higher on paper. The measured data confirms that the NVIDIA part delivers on its specification.

Architecture Differences

The Intel Arc Pro B370 is built on the Xe3-LPG architecture, part of the Arc Graphics-WM generation, using a Panther Lake chip. It is fabricated on a 3 nm process at Intel. The GPU has 1280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. It has no tensor cores listed. Its base clock is 300 MHz and boost clock is 2400 MHz. Memory is system shared, with a system-dependent bandwidth and no dedicated VRAM. The TDP is 25 W, and it is an integrated GPU (IGP) with no power connectors. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The release date is January 26, 2026, and its predecessor is HD Graphics-WM.

The NVIDIA GeForce RTX 4080 Mobile is based on the Ada Lovelace architecture, using an AD104 chip. It is fabricated on a 5 nm process at TSMC, with 35,800 million transistors on a 294 mm² die, giving a transistor density of 121.8 million per mm². The GPU has 7424 shading units, 232 TMUs, 80 ROPs, and 58 ray tracing cores. It also has 232 tensor cores, which the Intel part lacks. Its base clock is 1290 MHz and boost clock is 1665 MHz. Memory is 12 GB of GDDR6 on a 192-bit bus, with 432.0 GB/s bandwidth. The TDP is 110 W, and it uses a PCIe 4.0 x16 bus interface. It supports the same API set as the Intel part: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Its release date is January 2, 2023, its predecessor is GeForce 30 Mobile, and its successor is GeForce 50 Mobile.

The architectural differences are substantial. The RTX 4080 Mobile has roughly 5.8 times more shading units, 5.8 times more TMUs, 4 times more ROPs, and 5.8 times more ray tracing cores than the Intel part. It also has dedicated tensor cores, whereas the Intel GPU has none. The memory systems are fundamentally different: the NVIDIA part uses 12 GB of dedicated GDDR6 with a fixed bandwidth of 432.0 GB/s, while the Intel part relies on shared system memory with bandwidth that varies by the host system. The process nodes differ as well, with Intel using 3 nm and NVIDIA using 5 nm, though the NVIDIA chip packs far more transistors overall. The Intel chip’s die size and transistor count are listed as unknown, so a direct density comparison is not possible.

Clock behavior also differs. The Intel GPU has a lower base clock of 300 MHz but a higher boost clock of 2400 MHz, while the NVIDIA GPU has a higher base clock of 1290 MHz and a lower boost clock of 1665 MHz. This suggests the Intel part is designed to ramp up aggressively under load but idle very low, consistent with a 25 W integrated GPU. The NVIDIA part runs at a more sustained clock range within its 110 W TDP.

The Verdict

The data shows a clear separation between the two GPUs, but the comparison is limited by the Intel part’s lack of benchmark results. The RTX 4080 Mobile has measured scores across nine tests, with an average benchmark score of 38135 and a 81st percentile ranking among all GPUs. The Intel Arc Pro B370 has no measured scores and sits at the 50th percentile based on specifications alone.

For any workload where performance is measured, the RTX 4080 Mobile is the only option with confirmed data. Its Geekbench OpenCL and Vulkan scores of 159575 and 145807 indicate strong compute and graphics capability. Its Passmark G3D score of 24926 confirms solid gaming performance. The Intel part’s theoretical specifications, such as 6.144 TFLOPS FP32 and 48.00 GPixel/s pixel rate, are far below the RTX 4080 Mobile’s 24.72 TFLOPS and 133.2 GPixel/s, but without benchmarks, those numbers cannot be validated in practice.

The RTX 4080 Mobile also has a major architectural advantage in dedicated memory. Its 12 GB GDDR6 with 432.0 GB/s bandwidth is a fixed resource, while the Intel part’s system-shared memory introduces variability. For a user selecting a GPU for gaming or compute workloads, the RTX 4080 Mobile is the only part with recorded evidence of performance. The Intel Arc Pro B370, as a 25 W integrated GPU, is positioned for low-power portable devices, but the database contains no data to support any performance claim.

The nearest rivals for the RTX 4080 Mobile all fall within 1.3 percentage points of its average score. The MX570 and RTX 5080 Mobile are slightly faster, while the RTX 4070 and Tesla P4 are slightly slower. This clustering suggests the RTX 4080 Mobile is a mid-pack performer within its immediate competitive set, not an outlier in either direction.
