AMD reportedly bringing "dual-chiplets" to its X670 chipsets on Socket AM5 for Zen 4

AMD introduced its chiplet approach for the first time back when it unveiled Zen 2 in 2018. The chiplet design is a modular way to scale up multi-processing performance that's more efficient than simply adding more cores on a monolithic die.

Fast forward nearly four years today, a new report from Tom's Hardware suggests that AMD is so impressed by the effectiveness of the approach that it is using "dual-chiplets" to design its upcoming 600-series chipsets on next-gen Socket AM5. The report claims that this technology is only coming to the flagship X670 parts only and not to the mainstream B650 and entry-level A620 chipsets.

Today's report builds on an earlier report by Chinatimes which initially broke the story of the chiplet-based 600-series chipsets. However, there are no details so far on how these chiplets will work.

There's also more news on AM5 as the Tom's Hardware story also adds that the AMD LGA1718 AM5 socket will come with DDR5 support only. This means the next-gen AMD platform based around Zen 4 or Ryzen 7000 "Raphael" CPUs could be really expensive as DDR5 memory is still pretty exorbitant compared to the far more abundant DDR4. An earlier report had also suggested a similar thing that AMD could delay the introduction of next-gen RDNA 2 desktop APUs due to the high prices of DDR5 DRAM kits.

However, not all news is bad news when it comes to AM5's DDR5 side as Team Red has already confirmed that it is working hard to make sure high speeds are achievable for DDR5 memory. During a recent Meet the Experts webinar with Samsung, AMD's Memory Enabling Manager, Joseph Tao said the following:

Our first DDR5 platform for gaming is our Raphael platform and one of the awesome things about Raphael is that we are really gonna try to make a big splash with overclocking and I'll just kinda leave it there but speeds that you maybe thought couldn't be possible, maybe possible with this overclocking spec.

It is likely that AMD was referring here to its upcoming AMD Ryzen Accelerated Memory Profile (RAMP) technology which will succeed current A-XMP.
