DDR5 memories are reaching the mass PC market and the manufacturer Longsys has published some first results of the performance that they will offer compared to DDR4 memories.
DDR5 memory offers 53% more performance than DDR4
DDR5 RAM will be launched alongside the new generation of 12th Gen Intel Core processors, which will see the light of day later this year or early next year. By then, AMD should also fully support these next-gen memories.
Longsys has shared the tests he performed on two memory kits. The first kit has 16GB and the second has 32GB capacity. Both have speeds of 4800 MHz and CL40 times (40-40-40-77).
The test rig had an Alder Lake ES1 CPU (Engineering Sample 1) that has 8 cores and only ran at 800 MHz. This sample looks very early and the newer versions will likely have higher clock speeds.
Focusing on performance tests, DDR5-4800 MHz memory scored 53% higher than DDR4-3200 memory in the Ludashi tool (memory test). In AIDA64 tests, read speeds increase by 28% and write speeds are 27% with DDR5 memory.
With the higher clock speeds DDR5 memory has, latencies seem to double. We are talking about latencies of 56.8 ns for DDR4 memories, which go to 112.1 ns for DDR5 memories.
Intel Alder Lake-S will launch later this year. The new series is said to offer support for DDR4 and DDR5 memory depending on the motherboard used. Memory manufacturers have yet to announce mass production of the DDR5 kits.
