DDR4 vs DDR5 Intel Core i9-12900K Testing

Memory Benchmarks

In terms of memory bandwidth, DDR5 is a massive improvement over even highly clocked and dual-rank DDR4 kits. This comes as zero surprise to basically everybody, but it is good to visualise in chart form just how significant the bandwidth increase versus common spec DDR4 is.

Of course, the downside of DDR5 rears its head pretty quickly – latency. Timings numbers in the high thirties will never result in a good latency score. Add in the reduced memory controller frequency and the latency performance for DDR5 is not strong.

It will be interesting to see how this is shown in real world tests.
