DDR5 RAM format like Intel's Alder Lake series are part of two of the biggest tech launches of the coming months. Intel promised in its Architecture Day 2021 that their new series of Alder Lake CPUs were going to be especially compatible with the capabilities and potential of SRAM DDR5 memory.
Thanks to a leaker from China who has gotten a premature version of Alder Lake, the first DDR5 compatibility data has already been leaked. Of course, he warns, these are preliminary results with trial versions and without the corresponding drivers installed.
That's how well DDR5 and Intel Alder Lake get along
The leaked benchmarks were probably obtained thanks to a sample of hardware engineering by the manufacturer Dell and show a memory clock speed of 3200 MHz with a read and write speed of around 90 GB / s. Cas times and latency are still quite high, with results of 40-40-40 and 92,5 ns respectively.
When 40-40-40-85 DDR5 modules have been used; memory latency is astonishingly low at 92,5 ns despite the use of these times. The score given by the CPU-Z application for the single core of the Core i5 12600K that has been used for this benchmark is 785,6 points in the single core. Based on these results, the DDR5 memory has not delivered as surprising results as expected with an adapted CPU.
But as is often the case when introducing new technology, once memory module manufacturers gain some experience with DDR5, a significant improvement in the quality of memory modules on the market is expected. The results are still positive in the case of trial versions and hardly any optimization. From Guru3D they hope that in a short time, either with optimization or with overclocking techniques, the barrier of a speed of 100 GB / s reading in dual channel devices will be broken.
