"Mobile chips are given JEDEC rated memory. Latencies are the same for both sticks of memory, the higher freq means nothing. You're comparing DDR4-2666 CL16 (or was it 18, I forget) to DDR4-3200 CL22.\n\nActually, the Intel chips have superior latency from the Hardware Unboxed testing.\n\nhttps://www.techspot.com/review/2003-amd-ryzen-4000/\n\nThe other is the memory system. Yes, AMD offers higher memory bandwidth than Intel with the move to support DDR4-3200 speeds, Intel only offers DDR4-2666 with 9th-gen. In a benchmark like Sandra we see AMD providing around 35% more memory bandwidth. However, Ryzen 4000 appears to have inferior memory latency. This, like cache size can become a performance constraint. The Core i9-9880H has memory latency around 30ns for data sets above 32MB in size, while the Ryzen 9 4900HS has 46ns memory latency. That’s a substantial win for Intel."
