❶ A Core Ultra K series engineering sample has appeared on CPU-Z, featuring the Intel 4 process node and reaching 5 GHz, but lacking AVX-512 support. ❷ The sample is made on the B0 revision of silicon and uses the next-generation LGA 1851 socket. ❸ Intel has previously removed AVX-512 support from its hybrid CPUs, and this trend seems to be continuing with the Arrow Lake-S series.
