According to fresh rumors and leaks, a new image of the die of Intel’s next-gen Sapphire Rapids Xeon CPUs has surfaced online. These new images show us the MCM design that could house up to 60 cores. The leak is provided to us by Yuuki-AnS which shows a close-up of the dies that will power the 4th Gen Xeon lineup.
Last month also we got some leaked images of Intel’s 4th Gen Sapphire Rapids Xeon CPU dies however, it was a mystery as to what was inside those dies. This time, the leaker managed to expose each of the four chipsets dies on the main interposer.
So, there is a 4×4 (1 IMC tile) core configuration which means each die consists of up to 15 cores. It should be 16 core but 1 of the core area is taken up by the IMC. Therefore there are only 15 cores however, 1 core is disabled for better yields. This means that each die will in fact feature 14 cores for a total of 56 cores per CPU.
However, previous speculations also indicate that the Sapphire Rapids-SP Xeon CPUs could feature a maximum of 60 cores and 120 threads but we know from previous leaks that the maximum configuration is going to end up at 56 cores and 112 threads. Previously we also mentioned that some leaks offered insight on an ES chip that featured a total of 60 cores. But that chip only had 56 cores (14 cores per die) enabled.
