The Intel Arc B370 (or Arc Pro B370) Panther Lake iGPU with 10 Xe3-LPG cores is the second-fastest integrated graphics unit in the Intel Panther Lake SoC series, with up to 10 of the 12 Xe3 cores. The 10 Xe3 cores amount to 80 EUs and 1280 ALUs and also include 10 ray tracing cores. All cores can access 16 MB of L2 cache.
Performance is clearly above the older Intel Arc 140T in Arrow Lake, but remains significantly below the Arc B390 with 12 cores, which is, for example, 14% faster in 3DMark Fire Strike. The very demanding Assassin's Creed Shadows is barely playable in our test with the Honor MagicBook Pro 14. However, ARC Raiders, Call of Duty BO7, and F1 25 ran smoothly even at medium to high detail settings (see benchmarks below).
The new media engine now supports AV1 encode and decode, VVC decode, AVC 10-bit, and eDP 1.5. The iGPU benefits from support for fast LPDDR5-9600 (up to 96 GB) or DDR5-7200 (up to 128 GB) via a dual-channel memory controller.
The chiplet is manufactured at TSMC using the modern N3E process.
