AMD EPYC 9755 Server Processor
5th Gen EPYC · Turin (Zen 5) · Socket SP5 · OEM Tray
128-Core / 256-ThreadUp to 4.1 GHz512 MB L3 Cache12-Channel DDR5-6400 ECC
The AMD EPYC 9755 is a top-tier 5th Generation EPYC (Turin, Zen 5) server processor with 128 full Zen 5 cores and 256 threads, a 2.7 GHz base clock that boosts to 4.1 GHz, a colossal 512 MB of L3 cache and 12-channel DDR5-6400 ECC memory — built for high-performance cloud, HPC and AI infrastructure that needs both density and per-core throughput. Supplied as an OEM tray unit (part number 100-000001443) without a cooler. Typically in stock with fast delivery across Cyprus.
Compatibility — read before you buy
This is a server processor for the AMD Socket SP5 platform, compatible with SP5 server boards supporting 5th Gen EPYC (9005-series; a BIOS update may be required on Genoa-era boards). It requires registered ECC DDR5-6400 (RDIMM) across up to 12 channels (up to 6 TB) and supports 1- and 2-socket configurations. With a 500W TDP it requires a high-end server-class SP5 cooling solution and is supplied without a cooler.

Key Features
128 Full Zen 5 Cores
One hundred and twenty-eight full Zen 5 cores with SMT (256 threads) deliver class-leading throughput per socket with strong per-core performance for HPC and AI.
12-Channel DDR5-6400 ECC
Twelve channels of registered ECC DDR5-6400 (up to 6 TB) deliver enormous bandwidth and capacity with error correction for the most demanding in-memory and AI workloads.
512 MB L3 Cache
A massive 512 MB L3 cache keeps vast working sets close to the cores, accelerating databases, analytics, HPC and AI pipelines.
128 PCIe 5.0 Lanes
Up to 128 PCIe 5.0 lanes provide enormous I/O for NVMe arrays, GPUs/accelerators and high-speed networking, with 1P and 2P scalability.
Technical Specifications
Frequently Asked Questions
Singular Expert Insight
The EPYC 9755 is a top-tier Turin part using 128 full Zen 5 cores — it balances class-leading throughput with strong per-core performance and a huge 512 MB cache, ideal for HPC, AI and high-performance cloud. For maximum core density the 9965 (192 Zen 5c cores) goes further; for lower cost, fewer-core 9005 SKUs scale down. Pair it with registered ECC DDR5 memory across all twelve channels for maximum bandwidth.
Buyer's Guide
Buy it if
You operate cloud, HPC or AI infrastructure and want 128 full Zen 5 cores with 12-channel DDR5-6400, 512 MB cache and 128 PCIe 5.0 lanes per socket.
Skip it if
You need maximum core density (the 9965 has 192 cores), have smaller workloads (a lower-core EPYC is cheaper), or want a desktop CPU — this is a server-only SP5 part.
Also consider
The EPYC 9965 (192 cores) for density, lower-core 9005 SKUs for cost, or 4th Gen Genoa (9004) parts for established platforms.
