Intel's upcoming Xeon "Emerald Rapids" processors promise to bring exciting improvements, including increased cache size, advanced instructions, customizable power options, and up to 64 cores, making them a powerful choice for high-performance computing applications.

  • 64 cores and 448MB cache (L2+L3)
  • Support advanced instructions like AVX512 and AMX
  • Customizable power options

Intel’s upcoming XeonEmerald Rapids” processors are generating quite a buzz in the tech world. With a release date set for December 14th, these chips promise to bring some exciting improvements to the table. Building upon the success of the 4th Gen Sapphire Rapids lineup, the Emerald Rapids CPUs boast denser logic and a significant increase in cache size.
At the top of the Emerald stack sits the Xeon Platinum 8592+, a powerhouse with an impressive 64 cores and a massive 448MB cache (L2+L3). This beast of a processor comes with a power-hungry TDP (thermal design power) of up to 922W. It’s clear that Intel is aiming to deliver unmatched performance with this flagship CPU.
Thanks to a leaked image shared by Twitter user @792123a, we get an early glimpse of what the Xeon Platinum 8592+ has to offer. The image showcases a Qualification Sample (QS) running at a TDP of 350W. Similar to its predecessor, Sapphire Rapids, the Emerald Rapids CPUs utilize the Intel 7 node and support advanced instructions like AVX512 and AMX, which are absent from client chips.
One notable improvement in the Emerald Rapids lineup is the increase in cache size. Each core now packs 2MB of L2 cache, and there’s a shared L3 cache of 320MB, resulting in a total cache size of 448MB. This boost in cache capacity is expected to enhance overall performance and improve efficiency.
In terms of power limits, the Xeon Platinum 8592+ has a PL1 power limit of 350W and a PL2 limit of 420W. However, it can momentarily draw up to 500W as part of the PL4 specification. It’s worth noting that while the stock TDP is set at 350W, users have the flexibility to adjust it anywhere between 100W and a staggering 922W. This level of customization allows for fine-tuning the CPU’s power consumption based on specific requirements.
For those seeking extreme performance, the Xeon Platinum 8592+ can be configured in a 2S (dual-socket) setup, unleashing the full potential of these 64-core monsters. This configuration opens up possibilities for high-performance computing applications and demanding workloads that require immense processing power.
Intel’s Xeon “Emerald Rapids” CPUs are undoubtedly poised to make a significant impact in the server and data center market. With their increased cache size, improved architecture, and customizable power options, these processors are set to deliver exceptional performance and efficiency.
As the release date approaches, tech enthusiasts and professionals alike eagerly await the opportunity to get their hands on these powerful CPUs. Intel continues to push the boundaries of what’s possible in the world of server processors, and the Emerald Rapids lineup is yet another testament to their commitment to innovation.
