The latest 5th Generation Intel Xeon Scalable Processor, code named Emerald Rapids, follows the same microarchitecture design, leverages the same advanced accelerators, is manufactured on the same Intel 7 node process, and is socket compatible with the 4th Generation Intel Xeon Scalable Processor, allowing both the 5th Gen and 4th Gen families to be used on the same server motherboards and in the same server systems. There are however several changes in manufacturing and packaging that result in up to a 34% gain in performance depending on the application when compared to the 4th Gen product.
One of the primary design changes is that the 5th Generation Intel Xeon Scalable Processor uses two tile dies with up to 32 cores per tile for a maximum of 64 cores, compared to the 4th Generation Intel Xeon Scalable processor which uses four tiles and has a maximum core count of 60. The implementation of dual tiles reduces the complexity of the design by reducing the number of interconnects required to link all the resources. The resulting outcome is lower power consumption and lower latency. Additionally, the two tile design also allowed Intel to increase the amount of shared cache by up to 3x to 320MB. These design and engineering improvements along with a 25% increase in Intel’s UPI 2.0 throughput collectively contribute to the higher performance outcomes.
The 5th Generation Intel Xeon Scalable processor also has additional improvements in memory configurations with support for faster DDR5-5600 memory, up to 12 channels, on certain processor SKUs and support for Type 3 CXL memory, 4 channels, which combined dramatically increase memory capacity and bandwidth critical for big data workloads and other large in-memory databases.
As with the 4th Generation Intel Xeon processor, the 5th Gen series leverages the same accelerators to allow highly compute intensive tasks to be offloaded from the processor to the accelerator to dramatically improve core utilization and performance.
Why Accelerators Matter
It is predicted that by 2025, 90% of all enterprise applications will include some level of AI. Additionally, in the past year nearly 63% of all enterprises were breached to some extent so designing and integrating accelerators that help boost AI performance and help bring a zero trust security strategy to life while increasing overall performance make the 5th Generation Intel Xeon Scalable Processor the best and most flexible choice no matter the deployment path.
