There is a rumour going around that Intel’s upcoming Arrow Lake desktop CPUs will be able to support Clocked Unbuffered Dual Inline Memory Module (CUDIMM) RAM at frequencies of 10,000MT/s. The new memory module is acknowledged as the next step in the evolution of the current standard, UDIMM.
The news is interesting primarily because Intel’s 14th generation Raptor Lake Refresh CPUs struggle to exceed UDIMM speeds of 8,200MT/s. For more context, AMD’s latest Ryzen 9000 Series – we’ve got a couple more reviews for the incoming CPUs, so stay tuned – CPUs top out at 6,400MT/s. All in all, the ability to run at 10,000MT/s represents about a 20% uplift.
Suppose news of Intel Arrow Lake support for 10,000MT/s CUDIMM memory is through. In that case, it’ll also be a first in terms of JEDEC specifications – the body only mandates base speeds of 6,400MT/s for the memory standard but many CUDIMM kits that have already launched can sustain speeds of 9,600MT/s, which again, is impressive. The trade-off to this, however, is that at those speeds, the power consumption is higher, between 1.45V and 1.5V.
Additional rumours are also suggesting that Arrow Lake will support CUDIMM via a “Gear 2” mode, where the memory controller will be made to operate at half the DRAM data rate. Simply put, that would free up more resources from the processor’s memory fabric whilst allowing it to take advantage of the memory’s higher-than-average super-fast transfer rates.
