Intel Alder Lake-S will support DDR5 according to new benchmark

A new SiSoftware benchmark appeared online this week that purports to show DDR5 support for an Intel Alder Lake-S CPU as well as a new motherboard chipset and socket.

The benchmark, flagged by TechPowerUp, was posted to Twitter by @momomo_us and appears to show DDR5 support, which so far hasn't been confirmed by Intel. If valid, the benchmark is likely from a test system used by an engineer for either Intel or an OEM preparing for the release of Intel's 12th-generation Alder Lake-S desktop processors later this year.

The next generation of RAM, DDR5 will more than double the memory bandwidth of DDR4. Memory maker Adata is planning on releasing modules with 8,400MT/s compared to DDR4's rate of 3,200MT/s. The 8,400MT/s speed also represents the lower end of what DRR5 is capable of, with faster speeds to follow once the manufacturing process is refined.

Some good news for Intel on the desktop front

It has been rumored for a while now that Intel Alder Lake-S will support the next-generation of computer memory and both Adata and Samsung are fabricating DDR5 RAM as you read this, but so far its use has been limited to devices like the Samsung S21 Plus

The reason for this is that current motherboard chipsets don't support DDR5 RAM, so Intel is also introducing the new LGA 1700 socket, which motherboard manufacturers like MSI are already working on for release later this year.

Intel's silicon archrival AMD, meanwhile, isn't expected to start supporting DDR5 RAM until the release of their Zen 4 architecture sometime in 2022. If Intel releases a DDR5-supporting lineup of processors several months to a year before Team Red, then it would represent a solid advantage for Intel – something it could really use as of late. AMD ended Intel's 15-year dominance of the desktop CPU battle earlier this month when AMD processors edged out Intel's in desktop PC market share.

While exciting, it's also not something most of us will likely get our hands on this year regardless. The initial DDR5 RAM module are going to be selling at a premium and and will likely see use in servers and data centers before making its way down to the consumer market in any practical sense.

By then, AMD will likely have introduced Zen 4, limiting whatever advantage Intel has to first adopters and hardcore PC enthusiasts with a lot of money to burn.
