ECC DDR5-4800 vs. DDR5-5200 Memory Performance For AMD Ryzen Zen 4

Back when looking at the AMD Ryzen 7000 series budget server performance last year, DDR5-4800 ECC UDIMMs were used with the ASRock Rack 1U4LW-B650/2L2T Ryzen server given that's what was broadly available at the time. Since then there's been more ECC UDIMMs coming to market above DDR5-4800 speeds. Recently I bought a pair of Kingston Server Premier 32GB 5600MT/s DDR5 ECC CL46 UDIMMs (KSM56E46BD8KM-32HA) and that's the focus of today's tests. For those curious if the faster ECC UDIMMs are worthwhile compared to the commonality of DDR5-4800 ECC UDIMMs, these benchmarks are for you.
