The Intel Xeon Platinum 8592+ is a 64-core, 128-thread server processor supported in Dell’s PowerEdge R760. Its appeal is high parallel capacity, large cache, and eight-channel DDR5 memory; its trade-offs include a low 1.90 GHz base frequency and a 350 W thermal design power (TDP). It is a fit to evaluate for heavily parallel enterprise workloads—not a desktop upgrade—and published results only make sense when tied to their specific R760 configuration and software.
What the Xeon Platinum 8592+ offers
Intel identifies the 8592+ as a 5th Gen Intel Xeon Scalable processor, formerly code-named Emerald Rapids. Its headline specifications are:
- 64 cores and 128 threads, suited to workloads that can keep many hardware threads busy.
- 1.90 GHz base frequency and up to 3.9 GHz maximum turbo frequency. The maximum turbo figure is not a promise that all cores will sustain that speed.
- 320 MB cache, which can help workloads with suitable data-access patterns but does not by itself predict application performance.
- 350 W TDP, a significant cooling and power consideration for system design.
- 20 GT/s UPI and up to four UPI links, with support for two-socket scalability.
Intel also lists AMX, AVX-512, virtualization features, and accelerator technologies. Their presence is not a performance guarantee: benefits depend on the application, framework, software build, and whether the workload uses those capabilities. Check Intel’s 8592+ specifications against the software you intend to run.
Is the 8592+ supported in a PowerEdge R760?
Yes. Dell lists the Xeon Platinum 8592+ in the R760’s 5th Gen processor table. The R760 is a 2U, two-socket server that can be configured with up to two 5th Gen Xeon CPUs. A listed processor does not mean every R760 chassis or build can accept it unchanged: Dell’s guide includes thermal and cooling restrictions, and the exact requirements depend on the system configuration. Confirm the current full thermal matrix and the options in the specific server’s service and configuration documentation before ordering or upgrading.

The processor uses the FCLGA4677 socket. For a deployed server, socket fit is only one part of compatibility: validate the R760 system configuration, supported processor and firmware, cooling, power, and warranty implications with Dell. See Dell’s PowerEdge R760 technical guide and R760 product page.
Memory: processor limits versus R760 limits
Intel specifies up to 4 TB of memory per processor, eight memory channels, DDR5-5600 at one DIMM per channel, and ECC support. Dell’s R760 product page lists 32 DDR5 RDIMM slots and up to 8 TB maximum RAM for the platform. These are different ceilings: the processor specification is not the server’s guaranteed capacity, and the R760’s platform maximum does not mean every CPU, DIMM population, speed, or capacity combination is supported in every build.
For planning, verify the supported DIMM type and population rules for the exact R760 configuration. Memory channel population affects available bandwidth, while installed capacity should match the application’s working set. The right choice may be less than either published maximum.
What published performance evidence says—and does not say
Dell’s MLPerf Inference 4.0 configuration
Dell’s report dated April 22, 2024 describes a CPU-only PowerEdge R760 test system with two Xeon Platinum 8592+ processors, for 128 processor cores in total. The reported configuration used 2 TB of memory (16 × 128 GB at 5600 MT/s) and 7.68 TB of NVMe storage. The report discusses Intel AMX and optimized software in the context of inference.
This is useful evidence that Dell evaluated the processor in a substantial, dual-socket R760 configuration for a specific benchmark and software stack. It is not a result for a single-socket server, a generic inference deployment, or every model and serving setup. See the Dell MLPerf Inference 4.0 report for the test context.
Dell’s CPU INT Rate Base comparison
Dell reported a CPU INT Rate Base score of 1,070 for an R760 with a 5th Gen Xeon Platinum 8592+ (64 cores), based on Dell Performance Labs testing dated March 10, 2025. This is a vendor-reported figure in a comparison of specified Dell and Intel systems, not an independent review result or a matched comparison that establishes the best choice across all competing servers and workloads. Review the test context in Dell’s comparison and release.
Rank #4
Which workloads might justify 64 cores?
The 8592+ is most compelling when an application can use a large number of cores effectively and the server can supply the necessary memory, cooling, and power. Consider it for workloads such as highly parallelized enterprise compute or CPU-based inference only after checking application-level scaling and, for inference, the software’s support for relevant Intel features.
It may be a poor fit when the application is lightly threaded, strongly dependent on per-core speed, constrained by software licensing per core, or unable to use the processor’s parallel capacity. The 1.90 GHz base frequency and 350 W TDP make frequency needs and platform cooling particularly important parts of the evaluation. Core count and cache alone cannot settle whether the processor is faster or more economical for a particular deployment.

How to compare it with other R760 processors
Dell’s R760 guide also lists the 60-core Xeon Platinum 8580 and the 48-core Xeon Platinum 8568Y+. Compare the complete configuration against the workload rather than ranking CPUs by core count alone.
| R760 processor option | Cores | What to assess |
|---|---|---|
| Xeon Platinum 8592+ | 64 | Parallel throughput, per-core performance, memory demand, and 350 W cooling and power requirements. |
| Xeon Platinum 8580 | 60 | Whether its workload performance and configuration better suit the application than the 8592+; assess frequency, power, and supported build. |
| Xeon Platinum 8568Y+ | 48 | Whether fewer cores better balance the workload’s per-core needs, licensing, memory footprint, and system constraints. |
For all three, check the exact supported specifications in Dell’s R760 processor and thermal tables. A useful selection process weighs:
- Whether the application scales across many cores, and its performance on the specific software version.
- Per-core throughput and frequency behavior for latency-sensitive or lightly threaded work.
- Memory capacity and bandwidth needs, including DIMM population.
- One- versus two-socket deployment, including NUMA behavior and licensing rules.
- Cooling, power, accelerator requirements, and complete configured-system cost.
Is it worth choosing for your server?
The 8592+ is a credible R760 option when the workload can exploit 64 cores, benefits from the supported memory and instruction capabilities, and fits the system’s thermal and power envelope. The available vendor benchmarks demonstrate specific configurations, not universal application performance. For a procurement decision, benchmark the target software on a representative R760 configuration and compare the full system cost and licensing impact with the 8580 and 8568Y+ options.
This is an enterprise server processor. It is not a general-purpose desktop CPU upgrade; buyers should verify platform compatibility, cooling, firmware, and support with Dell for the exact system.”
