DDR5 memory capacity will influence newer Intel and AMD CPUs

The question is not really why? If not on the basis that Intel and AMD are having better memory performance. A filtered slide on DDR5 at Intel shows us more than interesting details and that once the CPUs are on sale it is convenient to understand, since the type of DDR5 memory in terms of ranks will be decisive.

Intel no longer tests DDR5 modules in its labs

In an attempt not to waste time or resources, Intel has transferred the tests of the new DDR5 products from the main RAM memory manufacturers to the company AVL (Advanced Validation Labs). As we well know, the certified speeds for Alder Lake and its CPUs will be DDR5-4800 MHz with a voltage of 1.1 and latencies of 40-39-39 for your JEDEC standard.

Then the manufacturers will tighten in speed or latency to their liking or possibilities, but the validation must begin in those terms for everyone, be it SK Hynix, Samsung, Micron, Crucial or Kingston. Curiously, the two best-selling brands are missing as they are CORSAIR and G.SKILL, although the document is from September 24 and has been updated.

In any case, the chips will again be SK Hynix, Samsung or Micron as expected and the die are also repeated curiously, since we will have Hynix M, Samsung B and Micron A.

The capacity of the DDR5 will indicate, in the vast majority of cases, the performance

So what is the problem? Well, assuming that the main manufacturer for the PMIC will be Renesas in your version P8911 which is the most advanced, what the document shows is that there will be many available Ranks or Ranks.

Keep in mind that most manufacturers will opt for 16 gigabit modules, it can be seen that the vast majority of kits opt for 1 rank in their modules due to their capacity. With AMD we know that dual rank modules are more optimal in terms of performance and apparently this will reportedly happen at Intel now as well.

The curiosity is that if we look closely, what we see is precisely that all 32 GB kits are dual rank, while the rest are single rank despite having 8 or 16 GB of capacity. So at least from the start, opt for 32GB or more seems to be synonymous with some modules that can give us more performance.

In addition, and according to the famous overclocker Toppc, the modules that exceed 4,800 MHz and that are considered as overclocked modules will need a special PMIC with higher voltage to be able to supply power to each of the sticks, which can make a difference if If necessary, several manufacturers enter the game and not just Remittances.
