Intel Graphics (Panther Lake, 4 Xe3-cores)

512 cores

Intel Graphics is the entry integrated GPU in the Core Ultra Series 3 (Panther Lake) mobile processors introduced at CES in January 2026. It is the four-Xe3-core configuration of Intel's Xe3 graphics, sitting below the ten- and twelve-core versions branded Arc B370 and B390, and keeps hardware ray tracing and the XMX AI engines. Host processors include the Core Ultra 9 386H and the low-power Core Ultra 7 355, with the graphics clock varying between models.

Notes
The XMX matrix engines deliver 40 INT8 TOPS on most Core Ultra Series 3 SKUs, and 37 TOPS on the lower-clocked Core Ultra 5 336H. That is the GPU figure alone; the separate NPU adds a further 47-50 TOPS.
