Intel Arc B370 Performance Overview
| Component | Score | Cores | Architecture |
|---|---|---|---|
| Arc B370 iGPU | 2,383 points | 10 Xe3 cores | Panther Lake |
| RTX 3050 Laptop | 2,186 points | N/A | Nvidia Ampere |
| RTX 3050 Ti Laptop | 2,485 points | N/A | Nvidia Ampere |
| Arc A380 (discrete) | 1,787 points | 8 Xe cores | Alchemist |
| Arc 140V (Lunar Lake) | 1,403 points | 8 Xe2 cores | Battlemage |
Game-Changing Efficiency
The Arc B370 operates at 2,300 MHz with a 36W power envelope on the Core Ultra 5 338H processor (45W TDP). Tested in FurMark at 2560×1440 using OpenGL API, the iGPU delivered 2,383 points—placing it between the RTX 3050 and RTX 3050 Ti laptop variants.
Most impressively, the B370 achieves 70% better performance than Lunar Lake’s Arc 140V iGPU despite only a 25% increase in core count (10 vs 8), showcasing massive architectural improvements in the Xe3 generation.
Not Even the Top Model
Intel hasn’t revealed its full hand yet. The B370 isn’t the flagship—that honor belongs to the Arc B390 with 12 Xe3 cores clocked at 2,500 MHz. Early B390 benchmarks show performance matching the RTX 3050 Ti consistently, with room for driver optimization before launch.
OpenGL Legacy Resolved
OpenGL previously plagued earlier Arc GPUs with poor performance, but Intel’s driver optimizations and Xe3 architecture refinements have largely resolved these issues by the Battlemage generation. This positions Panther Lake processors competitively against AMD’s Radeon 890M in the thin-and-light laptop segment.
CES 2026 Launch Expected
Intel will likely unveil complete Panther Lake specifications at CES 2026 in January. These processors target premium ultrabooks and portable workstations, bringing discrete-class gaming performance to integrated graphics for the first time.
