The Intel Xeon Platinum 8452Y is a 36-core, 72-thread server processor for enterprise workloads that benefit from parallel processing, such as virtualization, data services, and compute-intensive applications; it supports two-socket configurations, ECC memory, and up to 4 TB of DDR5 memory.
Recommended For
- Server operators consolidating many virtual machines or containers onto a host, especially when they can use the Xeon platform’s high memory capacity and bandwidth.
- HPC and simulation teams running well-parallelized workloads that can use many CPU cores; benchmark the specific application, since results depend on workload and configuration.
- Organizations running CPU-based AI or analytics workloads that have been optimized to use Sapphire Rapids features such as Intel AMX, and can verify gains with their own software.
- Data-center teams building a compatible one- or two-socket server for sustained compute, with infrastructure for the processor’s 300 W thermal design power.
Real-World Use Scenarios
- When consolidating several virtual machines on one server, an IT team can assign CPU capacity across multiple guest systems; how many VMs it can run comfortably will depend on their memory, storage, and workload demands.
- For parallel software builds or compile jobs, a development team can run more work at the same time on a server; build times still depend on how well the software and build process use multiple cores.
- For CPU-based AI inference, a team can test supported deep-learning models on the server without a separate accelerator; results depend on the model, software support, and performance requirements.
- For scientific or engineering workloads that use AVX-512, a research team can run compute-intensive jobs on the server CPU; actual throughput varies with the application and its optimization.
- For database server workloads, an administrator can run database jobs alongside other server tasks; end-user responsiveness and query throughput will also depend on the database configuration, memory, and storage.

Reference Q&A
Q: Xeon Platinum 8452Y or AMD EPYC 9354 for a server?
A: Choose the Xeon Platinum 8452Y if you need an Intel LGA4677 server that can scale to two sockets, or want its 36 cores and Intel AMX support. Choose the EPYC 9354 if you prefer a one-socket option with 12 memory channels and 128 PCIe 5.0 lanes. The 8452Y has 8 memory channels and 80 PCIe lanes; compare performance using benchmarks for your specific workload rather than core counts alone.
Q: Xeon Platinum 8452Y or 8462Y+ for multi-threaded workloads?
A: Choose the 8452Y when your workload can use more cores: it has 36 cores versus 32 in the 8462Y+. Choose the 8462Y+ when its higher stated base and maximum turbo frequencies better match your workload. Both are 300 W, LGA4677 processors; frequency and core counts alone do not establish which will finish a particular job sooner.
Q: Is the Xeon Platinum 8452Y a worthwhile upgrade from the 8352Y?
A: The 8452Y is a platform upgrade, not a drop-in CPU replacement. Compared with the 8352Y, it has 36 rather than 32 cores, supports DDR5-4800 and PCIe 5.0, and has a 300 W TDP rather than 205 W. The 8352Y uses LGA4189 with DDR4 and PCIe 4.0, while the 8452Y uses LGA4677, so moving to it requires a compatible platform. Consider the 8452Y when you need those newer platform capabilities and can accommodate its higher power requirement.
Q: Who is the Xeon Platinum 8452Y suitable for?
A: It is best suited to workstation or server builds that can use many CPU threads, large memory capacity, or multi-socket support. Its 36 cores, 72 threads, support for up to 4 TB of memory, and 2-socket scalability are aimed at demanding parallel workloads; for routine office use, those capabilities may be unnecessary. It requires a compatible LGA 4677 platform and a cooling solution, which is not included.
Q: Does the Xeon Platinum 8452Y come with a CPU cooler?
A: No. The product listing specifies that it is processor-only and does not include a cooling device. Plan for a cooling solution compatible with the LGA 4677 platform and suitable for a 300 W processor.
Q: Will this processor work with my current motherboard?
A: Only if the motherboard supports the Xeon Platinum 8452Y and its LGA 4677 socket. Socket fit alone is not enough to confirm support, so check the motherboard’s CPU-support list and platform requirements before buying; this is not a general-purpose drop-in desktop upgrade.
Q: What memory does the Xeon Platinum 8452Y support?
A: It supports ECC memory and up to 4 TB of memory, with eight memory channels. The listed supported memory is DDR5-4800 MT/s at one DIMM per channel or DDR5-4400 MT/s at two DIMMs per channel; confirm the motherboard’s supported memory configuration before choosing modules.
Q: Is the Xeon Platinum 8452Y a better choice than the 8444H for PostgreSQL?
A: The Reddit discussion does not establish that either CPU is faster for PostgreSQL; it raises the comparison but provides no benchmark result. The 8452Y is a 36-core, 72-thread processor rated for two-socket scalability. Compare performance on your PostgreSQL workload and total platform cost before choosing.
Q: Is it worth paying extra for an H-series Xeon if the server will use no more than two CPUs?
A: A Reddit commenter says the H suffix is relevant to systems with more than two physical CPUs and questions paying extra when a server uses two or fewer. The 8452Y is listed as supporting two-socket configurations, so check the price difference and required socket count before paying more for another SKU.
