The 8-channel Diamond Rapids server processors have been dropped due to Intel's focus on achieving higher memory bandwidth.
Intel Reportedly Drops 8-Channel Diamond Rapids Series to Focus Just on 16-Channel Variant Due to Memory Benefits
Looks like there is a big shift that occurred in Intel's server segment product roadmap due to the new Data Center Group leadership. As per the new report, the upcoming Xeon 7, aka Diamond Rapids, is set to see the cancellation of one of its CPU families. Intel Diamond Rapids, which is scheduled for a 2026 release, is now getting its 8-Channel Diamond Rapids series ditched by Intel.
The 8-channel Diamond Rapids succeeds the Xeon 6, aka Granite Rapids-SP processors, and according to Intel's comment, it no longer sees it useful for the server market due to higher memory demand.
We have removed Diamond Rapids 8CH from our roadmap. We’re simplifying the Diamond Rapids platform with a focus on 16 Channel processors and extending its benefits down the stack to support a range of unique customers and their use cases.
- Intel to STH
It's clear that Intel will now focus only on the 16-channel Diamond Rapids due to higher capacity memory support, and also due to the availability of higher memory bandwidth on the upcoming platform. It appears that 12-channel isn't that useful either, which has some constraints, and only 16-channel variants can help Intel to achieve superior bandwidth, density, and I/O to allow data-center workloads to scale.
Modern server workloads such as AI training/inference and large-scale virtualization are extremely memory-bandwidth hungry. More channels will create more parallel data paths between the CPU and the DRAM to solve this problem. Moreover, some reports suggest that 16-channel Diamond Rapids will also support a very high memory frequency of up to 12,800 MT/s, delivering up to 1.6 TB/s of memory bandwidth.
Since Intel has to compete with AMD's EPYC series, which is also moving to high memory-channel counts, it is a no-brainer for Intel to switch to a 16-channel memory configuration to maintain/increase its server CPU share. Even though the 8-channel design had its cost benefits, it will have shrinking benefits in the long run, considering the modern intensive workloads. So, Intel's new strategy indicates that it wants to balance between both cost and performance for the long run, which can help it go head-to-head with AMD in the server segment.
