Analysis: Intel Arc B370 vs Intel Arc Pro B50
The Verdict
The benchmark data separates these two Intel GPUs clearly. The Intel Arc Pro B50 is the stronger part, winning the only shared test, 3DMark Steel Nomad DX12, with a score of 1604 against 1184 for the Intel Arc B370, a 26.2% advantage. The Arc Pro B50 also sits higher in the overall database, at the 17th percentile of all GPUs, while the Arc B370 is at the 5th percentile.
The Arc B370 is an integrated graphics processor (IGP) built for Panther Lake mobile chips. It uses system shared memory and draws only 25 W, making it suitable for thin, portable devices where space and power are limited. The Arc Pro B50 is a discrete, dual-slot card with 16 GB of dedicated GDDR6 memory, a 70 W power draw, and a suggested 250 W power supply. It is designed for professional workstations that need consistent rendering performance across multiple display outputs.
The data indicates a user should pick the Arc Pro B50 when dedicated graphics memory and higher throughput are required. The Arc B370 is the choice when the system must rely on integrated graphics and cannot accommodate a discrete card. The Arc Pro B50 outperforms the Arc B370 in the recorded benchmark, but it is not a compact, low-power solution.
Architecture Differences
The two GPUs come from different Intel design families and are built on different process nodes. The Arc B370 uses the Panther Lake chip with Xe3-LPG architecture, built on Intel's 3 nm process. The Arc Pro B50 uses the BMG-G21 chip with Xe2-HPG architecture, built on TSMC's 5 nm process. The Arc Pro B50 has a transistor count of 19,600 million across a 272 mm² die, with a transistor density of 72.1M per mm². The Arc B370 does not have transistor or die size data recorded.
The Arc Pro B50 has more execution resources. It contains 2048 shading units, 128 texture mapping units, 16 render output units, and 16 ray tracing cores. The Arc B370 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 RT cores. The Arc Pro B50 has a higher boost clock at 2600 MHz, while the Arc B370 boosts to 2400 MHz and has a base clock of 300 MHz versus 1700 MHz for the Arc Pro B50.
Memory architecture differs substantially. The Arc B370 uses system shared memory, with bandwidth dependent on the host system. The Arc Pro B50 uses 16 GB of GDDR6 on a 128 bit bus, delivering 224.0 GB/s bandwidth. The Arc Pro B50's memory runs at 1750 MHz with 14 Gbps effective speed. The Arc B370 has no dedicated memory bus width or bandwidth figures.
The Arc Pro B50 is a dual-slot PCIe 5.0 x8 card measuring 167 mm by 69 mm by 40 mm. It has four mini-DisplayPort 2.1 outputs and requires no power connectors. The Arc B370 is an IGP with no slot width, no power connectors, and display outputs dependent on the portable device. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Arc Pro B50 was released on September 4, 2025, while the Arc B370 followed on January 26, 2026.
Where Each One Wins
The only direct comparison in the database is 3DMark Steel Nomad DX12, where the Arc Pro B50 wins by 26.2%. That test reflects modern DirectX 12 rendering workloads, and the Arc Pro B50's dedicated memory and higher shading unit count contribute to the result.
The Arc Pro B50 also has a broader benchmark record. The database lists PassMark scores for DirectX 9, 10, 11, 12, G2D, G3D, and compute. The G3D score is 12553, the compute score is 6037, and the G2D score is 717. DirectX 9 returns 144, DirectX 11 returns 100, DirectX 12 returns 64, and DirectX 10 returns 58. The Arc B370 has no PassMark entries, so its performance in those legacy and compute workloads is not recorded.
The Arc B370 wins in power efficiency and physical integration. It draws 25 W versus 70 W for the Arc Pro B50, and it occupies no expansion slot. The Arc B370's pixel rate is 48.00 GPixel/s, slightly higher than the Arc Pro B50's 41.60 GPixel/s. The Arc B370 also has a higher texture-to-pixel balance in one metric, but the Arc Pro B50 delivers 332.8 GTexel/s versus 96.00 GTexel/s for the Arc B370. FP32 throughput is 10.65 TFLOPS for the Arc Pro B50 and 6.144 TFLOPS for the Arc B370. FP16 is 21.30 TFLOPS versus 12.29 TFLOPS, both at a 2:1 ratio.
The Arc Pro B50 is the clear winner for heavy rendering, compute, and professional graphics tasks. The Arc B370 is the winner for low-power integrated use cases where the system must run without a discrete card.
