What memory access architecture has an i9 processor?
What memory access architecture has and i9 processor (UMA ,NUMA OR CC-NUMA)?
Is it different from previous processors like i7?
Intel is using NUMA in its new Skylake chips, but with a new (mesh) topology that defeats some of the negative effects of NUMA.
Intel is abandoning the ring topology it's used to connect CPU cores in its many-core CPUs for several generations. In place of its ring, the company is introducing a new mesh interconnect topology that promises several improvements. First off, Intel says its mesh interconnect delivers lower latency and higher bandwidth than the ring bus, all while operating at a lower frequency and voltage. Those last two characteristics are important, because they should result in less power consumption from the interconnect portion of the chip as it scales up. The mesh topology in Skylake-X should make headaches from the non-uniform distribution and access latencies of resources among rings a thing of the past.
