DDR5 RAMs basically made their consumer debut last year, thanks to the platform that hosted Intel’s 12th generation processors. However, Adler Lake processors also supported DDR4 memory at the same time, with many consumers preferring these motherboards as DDR5 prices are still quite high today.
Apparently, the same won’t apply to AMD’s new processors. Specifically, as reported by Tom’s Hardware, so far all indications are that the next generation of AM5 platforms and 5nm Ryzen 7000 “Raphael” processors will initially only support DDR5 memory when it comes to market later in 2022. So far this has not been confirmed by the company, but the tipster has managed to verify from several sources that the upcoming X670 and B650 motherboards will be able to run exclusively on DDR5 memory.
Of course, this will have significant implications for the cost of a new AM5 configuration, as Intel’s upcoming Raptor Lake has already been confirmed to offer PC builders the most affordable DDR4 memory option.
At this point it’s worth noting that AMD has so far announced that its AM5 platform, which will replace the older AM4, will support both PCIe 5.0 and DDR5 memory, as is already the case with its Intel Alder Lake processors. However, AMD has not only not confirmed whether DDR4 will be an option, but as of yet, it’s not even clear whether the Ryzen 7000 memory controller will be able to run DDR4. Tom’s Hardware sources point out that the X670 and B650 motherboards won’t have devices with DDR4 support, so the only possible possibility is for AMD to prepare a new A chipset for more economical motherboards with DDR4. Unfortunately, the media notes that its sources don’t give much chance in this scenario.
Historically, due to pandemics and other factors, DDR5s continue to be much more expensive than DDR4 memory, with little or no performance difference in many applications. However, it’s an important step, as it’s the first generation of mainstream memories with integrated power management IC (PMIC) and VRMs. So hopefully AMD’s move will shake up the market and may help prices gradually come down.
