Intel Core Ultra 200 to Support 10000MT/s DDR5

Intel’s upcoming Arrow Lake "Core Ultra 200" desktop CPUs are set to introduce the latest CUDIMM technology, significantly boosting support for DDR5 memory speeds, ranging from 8000MT/s to 10000MT/s. Over the past three generations of CPUs, Intel has consistently delivered higher DDR5 memory speed support compared to its main competitor, AMD. With Arrow Lake’s release on the horizon, reports suggest that these CPUs will fully support high-speed CUDIMM DDR5 memory.

CUDIMM, a cutting-edge DDR5 memory module introduced this year, is designed to offer higher memory speeds. Leaks indicate that the Arrow Lake processors will support DDR5 memory speeds from 8000MT/s to 10000MT/s through CUDIMM technology. This is a significant leap compared to Intel's Raptor Lake and Raptor Lake Refresh CPUs, which struggled to hit 8000MT/s due to the need for a robust integrated memory controller (IMC). On AMD’s AM5 platform, achieving DDR5 memory speeds beyond 7000MT/s has been challenging, particularly with Ryzen 7000 and 9000 CPUs. Arrow Lake’s improved memory speed support places Intel ahead once again.

CUDIMM technology integrates a clock driver that regenerates clock signals to enhance stability and boost memory frequency. While reaching 10000MT/s seems ambitious, it is within reach as memory manufacturers have already started producing high-speed CUDIMM modules. One notable example is Asgard, which recently introduced CUDIMM DDR5 modules with speeds up to 9600MT/s.

As memory speeds continue to rise, manufacturers are aiming to surpass the 10000MT/s mark. Intel's upcoming LGA 1851 motherboards are also expected to support these higher memory speeds. Although details about Z890 chipset motherboards are still emerging, reports indicate that the ASRock Z890 Taichi will support memory speeds up to 9200MT/s in a 1DPC 1R configuration, representing a 2000MT/s increase compared to the Z790 Taichi.

While it might be too early to confirm whether Arrow Lake CPUs will support 10000MT/s DDR5 memory speeds upon launch, with motherboard and memory manufacturers targeting faster speeds, this is likely to become a reality soon.
