Apparently the AMD "Strix Halo" processor is real, and it's large. The chip is designed to square off against the likes of the Apple M3 Pro and M3 Max, in letting ultraportable notebooks have powerful graphics performance. A chiplet-based processor, not unlike the desktop socketed "Raphael," and mobile BGA "Dragon Range," the "Strix Halo" processor consists of one or two CCDs containing CPU cores, wired to a large die, that's technically the cIOD (client I/O die), but containing an oversized iGPU, and an NPU. The point behind "Strix Halo" is to eliminate the need for a performance-segment discrete GPU, and conserve its PCB footprint.
According to leaks by Harukaze5719, a reliable source with AMD leaks, "Strix Halo" comes in a BGA package dubbed FP11, measuring 37.5 mm x 45 mm, which is significantly larger than the 25 mm x 40 mm size of the FP8 BGA package that the regular "Strix Point," "Hawk Point," and "Phoenix" mobile processors are built on. It is larger in area than the 40 mm x 40 mm FL1 BGA package of "Dragon Range" and upcoming "Fire Range" gaming notebook processors. "Strix Halo" features one or two of the same 4 nm "Zen 5" CCDs featured on the "Granite Ridge" desktop and "Fire Range" mobile processors, but connected to a much larger I/O die, as we mentioned.
