Intel Arc B370 vs NVIDIA GeForce RTX 4050 Mobile Comparison

The Intel Arc B370 and NVIDIA GeForce RTX 4050 Mobile occupy very different positions in the database, and the benchmark data reflects that clearly. The Arc B370 is an integrated graphics processor embedded in Intel’s Panther Lake platform, while the RTX 4050 Mobile is a dedicated laptop GPU from NVIDIA’s Ada Lovelace generation. Their recorded scores, architectural choices, and performance contexts make for a straightforward comparison.

Head-to-Head Benchmarks

The database contains a single benchmark entry for the Intel Arc B370: a 3DMark Steel Nomad DX12 score of 1184. This places the chip in the 5th percentile among all GPUs in the database, indicating that it sits near the lower end of the performance range. Its nearest rivals are older or low-end parts: the ATI Mobility Radeon HD 5570 averages 1186 (a delta of -0.2%), the ATI Radeon HD 5770 averages 1190 (a delta of -0.5%), and the AMD Radeon HD 7650M averages 1192 (a delta of -0.7%). The AMD FirePro M2000, with an average score of 1168, trails the Arc B370 by 1.4%. In other words, the Arc B370’s measured performance is essentially on par with a decade-old discrete mobile GPU, with deltas under 1% in either direction.

The NVIDIA GeForce RTX 4050 Mobile, by contrast, has a much richer benchmark record. Its average benchmark score across nine tests is 19049, which lands it in the 63rd percentile of all GPUs. Its nearest rivals include the AMD Radeon RX 6600 (average 19036, delta 0.1%), the NVIDIA Quadro K6000 (average 19030, delta 0.1%), the NVIDIA Tesla K20m (average 19089, delta -0.2%), and the NVIDIA RTX 2000 Ada Generation (average 18954, delta 0.5%). The RTX 4050 Mobile’s individual scores vary widely by test: it reaches 74748 in Geekbench OpenCL, 75235 in Geekbench Vulkan, 14423 in Passmark G3D, and 5947 in Passmark GPU Compute. Its Passmark DirectX scores are far lower, at 184 for DX9, 130 for DX11, 79 for DX10, and 61 for DX12, while the Passmark G2D score is 633.

A direct head-to-head comparison using a common benchmark is not possible from the recorded data, as the Arc B370 was only tested with 3DMark Steel Nomad DX12, and the RTX 4050 Mobile was not tested with that workload. However, the percentile data alone tells a decisive story: the Arc B370 sits at the 5th percentile, while the RTX 4050 Mobile sits at the 63rd percentile. That 58-point gap in percentile ranking indicates a substantial performance separation, far larger than the small deltas seen among each chip’s own nearest rivals.

The RTX 4050 Mobile’s average score of 19049 is more than 16 times the Arc B370’s single recorded score of 1184. Even accounting for the fact that the average includes multiple workloads, the raw numbers show that the dedicated NVIDIA part delivers a much higher level of computational throughput. The Arc B370’s nearest rival deltas are all within ±1.5%, which suggests that its performance is tightly clustered with those older parts, whereas the RTX 4050 Mobile’s nearest rivals are modern desktop and workstation GPUs with similar average scores. In short, the data indicates that the RTX 4050 Mobile outperforms the Arc B370 by a wide margin in every recorded category that overlaps, though the lack of a shared test prevents an exact percentage delta.

Architecture Differences

The two processors are built on fundamentally different foundations. The Intel Arc B370 uses the Xe3-LPG architecture, fabricated on Intel’s 3 nm process node, and is part of the Arc Graphics-M (Panther Lake) generation. Its chip is called Panther Lake, and it operates as an integrated GPU (IGP) with no dedicated memory, relying on system shared memory for both capacity and bandwidth. The base clock is 300 MHz with a boost clock of 2400 MHz. The shading unit count is 1280, with 40 texture mapping units, 20 render output units, and 10 ray tracing cores. There are no tensor cores listed. The pixel rate is 48.00 GPixel/s, the texture rate is 96.00 GTexel/s, and floating-point performance is rated at 6.144 TFLOPS for FP32 and 12.29 TFLOPS for FP16 (at a 2:1 ratio). The thermal design power is 25 W, and the bus interface is IGP, meaning it connects directly to the processor rather than through a PCIe slot.

The NVIDIA GeForce RTX 4050 Mobile uses the Ada Lovelace architecture, built on TSMC’s 5 nm process. The chip is AD107, with 18,900 million transistors on a 159 mm² die, giving a transistor density of 118.9 million per mm². The base clock is 1455 MHz, and the boost clock is 1755 MHz. It has 2560 shading units, 80 TMUs, 48 ROPs, 20 ray tracing cores, and 80 tensor cores. The pixel rate is 84.24 GPixel/s, the texture rate is 140.4 GTexel/s, and FP32 performance is 8.986 TFLOPS with FP16 at the same 8.986 TFLOPS (1:1 ratio). The memory subsystem is dedicated: 6 GB of GDDR6 on a 96-bit bus, with a bandwidth of 192.0 GB/s and a memory clock of 2000 MHz (16 Gbps effective). The TDP is 50 W, and it connects via PCIe 4.0 x8.

Several architectural contrasts stand out. The Arc B370 uses a newer process node (3 nm versus 5 nm) but has far fewer shading units (1280 versus 2560), fewer TMUs (40 versus 80), fewer ROPs (20 versus 48), and half the ray tracing cores (10 versus 20). The RTX 4050 Mobile also includes 80 tensor cores, which the Arc B370 lacks entirely. The FP32 throughput of the RTX 4050 Mobile is 8.986 TFLOPS versus 6.144 TFLOPS for the Arc B370, a 46% advantage. The RTX 4050 Mobile’s pixel rate (84.24 GPixel/s) is 75% higher than the Arc B370’s 48.00 GPixel/s, and its texture rate (140.4 GTexel/s) is 46% higher than 96.00 GTexel/s. The memory situation is the most critical difference: the RTX 4050 Mobile has 192.0 GB/s of dedicated bandwidth, while the Arc B370’s bandwidth is labeled as system dependent, meaning it shares the CPU’s memory bus and cannot guarantee any fixed figure.

The API support is identical: both list DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The power draw also differs, with the Arc B370 rated at 25 W and the RTX 4050 Mobile at 50 W, though both are classified as IGP in slot width and use no power connectors, as they are designed for portable devices. The RTX 4050 Mobile’s release date is recorded as 2023-01-02, while the Arc B370’s release date is 2026-01-26, indicating a three-year gap in market introduction.

The Verdict

From the recorded data, the NVIDIA GeForce RTX 4050 Mobile is the clear performance leader. Its average benchmark score of 19049 places it in the 63rd percentile, while the Intel Arc B370’s single 3DMark Steel Nomad score of 1184 places it in the 5th percentile. The RTX 4050 Mobile also offers dedicated 6 GB GDDR6 memory with 192.0 GB/s bandwidth, whereas the Arc B370 depends on system shared memory with system-dependent bandwidth. The RTX 4050 Mobile doubles the shading units, TMUs, and ray tracing cores, and adds tensor cores that the Arc B370 does not have. Its FP32 throughput is 8.986 TFLOPS versus 6.144 TFLOPS.

The Intel Arc B370 does have advantages in the data, but they are limited to power efficiency and process technology. It uses a 3 nm process versus 5 nm, and its 25 W TDP is half the RTX 4050 Mobile’s 50 W. For a system that requires integrated graphics with no separate VRAM allocation and very low power draw, the Arc B370 is the only option, as the RTX 4050 Mobile requires a discrete implementation. However, the benchmark results indicate that the RTX 4050 Mobile delivers more than 16 times the average score, and its nearest rivals are modern GPUs like the AMD Radeon RX 6600 and NVIDIA RTX 2000 Ada Generation, while the Arc B370’s nearest rivals are over a decade old. Users who need raw graphics performance, ray tracing capability, or tensor core acceleration should choose the RTX 4050 Mobile based on these measurements. Users who require an integrated solution with no dedicated memory and minimal power consumption would select the Arc B370, but they must accept a performance level that the database places near the bottom of all GPUs.
