Intel Arc B370 vs NVIDIA GeForce RTX 5050 Mobile Comparison

Intel Arc B370 and NVIDIA GeForce RTX 5050 Mobile occupy very different positions in the mobile graphics landscape, with the recorded data showing a substantial performance gap between them. The Intel part is an integrated graphics processor built for Panther Lake platforms, while the NVIDIA solution is a discrete-class mobile GPU with dedicated memory. Benchmark results from the database indicate that the RTX 5050 Mobile delivers roughly double the performance of the Arc B370 in the primary DirectX 12 test, placing them in entirely separate performance tiers.

Where Each One Wins

The NVIDIA GeForce RTX 5050 Mobile wins the only direct head-to-head benchmark recorded in the database. In the 3DMark Steel Nomad DX12 test, the RTX 5050 Mobile scores 2365 points against 1184 points for the Intel Arc B370, a delta of -49.9% from the perspective of the Intel part. This is not a marginal advantage; the NVIDIA GPU delivers approximately one full doubling of the frame throughput in this workload. Across the entire database, the RTX 5050 Mobile sits at the 83rd percentile of all GPUs, while the Arc B370 sits at the 5th percentile. That percentile gap confirms that the NVIDIA part competes in a much higher performance bracket.

The Intel Arc B370 does not win any recorded benchmark against the RTX 5050 Mobile. There are zero wins recorded for the Intel part in the head-to-head data. However, the Arc B370 does show a narrow edge over its own nearest rivals in the database. It scores 1.4% higher than the AMD FirePro M2000, which averages 1168 points. The Arc B370 also edges out the ATI Mobility Radeon HD 5570 by 0.2%, the ATI Radeon HD 5770 by 0.5%, and the AMD Radeon HD 7650M by 0.7%. These are extremely tight margins, indicating that the Arc B370 is positioned among older discrete mobile GPUs in raw 3DMark performance, not against modern dedicated parts.

The RTX 5050 Mobile, by contrast, sits in a cluster with much more powerful hardware. Its average benchmark score of 43268 across all recorded tests places it within 0.1% of the NVIDIA Quadro M6000 24 GB and the NVIDIA GeForce RTX 4070 SUPER, and within 0.9% of the NVIDIA GeForce RTX 4090 Mobile. The OpenCL score of 84171 for the RTX 5050 Mobile further demonstrates its compute capability, a result the Arc B370 has no comparable data for in this database. The use-case split is therefore clear: the RTX 5050 Mobile is for workloads requiring high 3D throughput, while the Arc B370 serves as a low-power integrated option.

Architecture Differences

The two GPUs come from entirely different architectural lineages. The Intel Arc B370 uses the Xe3-LPG architecture, built on a 3 nm process node by Intel, and is part of the Arc Graphics-M (Panther Lake) generation. The NVIDIA GeForce RTX 5050 Mobile uses the Blackwell 2.0 architecture, fabricated by TSMC on a 5 nm process, and belongs to the GeForce 50 Mobile generation. The process node difference is notable: Intel uses a smaller 3 nm node, yet the NVIDIA part still achieves far higher performance, indicating that architectural efficiency and resource allocation matter more than raw process geometry here.

The compute resources differ substantially. The Intel Arc B370 has 1280 shading units, 40 texture mapping units, and 20 raster output units. The NVIDIA part has double the shading units at 2560, double the TMUs at 80, and 32 ROPs. Ray tracing hardware also differs: the Arc B370 has 10 RT cores, while the RTX 5050 Mobile has 20. The NVIDIA GPU additionally includes 80 tensor cores, a feature the Intel part does not list at all. These resource differences directly explain the benchmark gap. With twice the shader count and twice the RT core count, the RTX 5050 Mobile has substantially more parallel execution capacity.

Clock behavior further separates the two. The Intel Arc B370 has a base clock of 300 MHz and a boost clock of 2400 MHz, while the NVIDIA RTX 5050 Mobile runs at a 1020 MHz base and 1500 MHz boost. The Intel part boosts much higher, but its lower base clock and smaller shader array limit sustained throughput. In terms of fill rates, both GPUs achieve exactly 48.00 GPixel/s pixel throughput, but the RTX 5050 Mobile delivers 120.0 GTexel/s texture rate against 96.00 GTexel/s for the Arc B370. Floating-point performance tells a similar story: the RTX 5050 Mobile delivers 7.680 TFLOPS FP32, while the Arc B370 delivers 6.144 TFLOPS. The Intel part does offer higher FP16 throughput at 12.29 TFLOPS using a 2:1 ratio, while the NVIDIA GPU lists 7.680 TFLOPS FP16 at 1:1, but the FP32 numbers are the more relevant comparison for most 3D workloads.

Memory architecture is a fundamental divider. The Intel Arc B370 uses system shared memory, with system-dependent bandwidth, meaning it borrows from the host's main memory. The NVIDIA RTX 5050 Mobile has 8 GB of dedicated GDDR7 memory on a 128-bit bus, delivering 384.0 GB/s of bandwidth. The memory clock is listed as 1500 MHz with 24 Gbps effective transfer for the NVIDIA part, while the Intel part has no dedicated memory clock because it relies on shared system resources. This dedicated memory arrangement gives the RTX 5050 Mobile a massive bandwidth advantage, which directly benefits texture-heavy and high-resolution workloads.

Power and interface specifications also differ. The Intel Arc B370 has a TDP of 25 W, while the RTX 5050 Mobile has a TDP of 50 W. Both are integrated into mobile platforms with no power connectors and portable-device-dependent display outputs. The Intel part uses an IGP bus interface, while the NVIDIA GPU uses PCIe 5.0 x16. The NVIDIA chip contains 16,900 million transistors on a 149 mm² die with a density of 113.4M per mm², while the Intel transistor count and die size are unknown in the database. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature coverage is identical.

The Verdict

The recorded data indicates that the NVIDIA GeForce RTX 5050 Mobile is the clearly faster GPU in 3DMark Steel Nomad DX12, scoring 2365 against 1184 for the Intel Arc B370. That is a 49.9% deficit for the Intel part, a margin that places the Arc B370 at the 5th percentile of all GPUs while the RTX 5050 Mobile sits at the 83rd percentile. For any user whose primary concern is 3D rendering performance, the RTX 5050 Mobile is the choice supported by the benchmark data.

The Intel Arc B370 is not without a role. Its 25 W TDP is half that of the NVIDIA part, and it uses system shared memory, which means it carries no dedicated VRAM overhead. It is an integrated GPU on an IGP bus interface, suitable for lightweight graphics tasks on Panther Lake platforms. Its benchmark scores place it near older discrete parts like the ATI Radeon HD 5770 and AMD Radeon HD 7650M, which suggests it can handle basic 3D acceleration but not demanding modern titles at high settings. The RTX 5050 Mobile, with 8 GB of GDDR7 and 384.0 GB/s bandwidth, is in a completely different class for gaming and GPU-accelerated work.

The choice between these two depends entirely on the platform and workload. The Arc B370 is the only option for systems built around Panther Lake integrated graphics, and its power envelope is suited to thin-and-light designs. The RTX 5050 Mobile is a discrete GPU, despite its IGP slot width, and its performance data justifies its higher power draw. Users who need the fastest recorded 3D performance should select the RTX 5050 Mobile. Users who need an integrated solution with minimal power draw and shared memory should look to the Arc B370.
