AMD EPYC 4245P

The AMD EPYC 4245P is a 6-core, 12-thread Zen 5 processor aimed at the server/workstation segment, but it mounts on AMD Socket AM5 and carries a 5.40 GHz boost clock that rivals desktop parts. Its average benchmark score of 39,383 places it at the 90th percentile of all CPUs, and the nearest-rival data shows it trading blows with the Ryzen 9 5900X, Core i7-13700F, Ryzen 7 PRO 8845HS, and Xeon 6369P. The result is an entry EPYC that behaves like a fast desktop chip with server-grade memory and ECC support, wrapped in a 65 W envelope.

Who Should Consider It

The EPYC 4245P fits workloads that need strong single-thread performance in a server context. Its Passmark single-thread score of 4,603 and Cinebench R23 single-core score of 3,757 are high for the server/workstation segment, making it well suited to database engines, control-plane services, and lightly threaded network daemons where per-core latency matters more than raw core count. The 5.40 GHz boost clock reinforces this profile; benchmark results indicate that latency-sensitive tasks will see responsiveness close to what desktop flagship parts deliver.

For multi-threaded creation work, the chip is capable but not a core-count monster. The Cinebench R23 multi-core score of 26,618 and R20 multi-core of 11,179 show solid scaling across the 12 threads, and the Passmark integer math score of 95,253 indicates strong performance in compile jobs, scripted builds, and data transformation pipelines. Floating-point math comes in at 58,045, which is respectable for physics simulation and financial modeling at this core count. The Passmark data compression score of 340,354 and random string sorting score of 41,253 point to good behavior in log processing, archival tasks, and file-serving workloads that hammer memory bandwidth.

Office and general server duties are a natural fit. The 89.6 GB/s dual-channel DDR5 bandwidth, combined with the 32 MB shared L3 cache, gives the 4245P enough headroom for virtualization hosts running modest VM counts or containerized microservices. The integrated Radeon Graphics also means a headless server can drive a basic display without a discrete GPU, which simplifies initial setup and troubleshooting. Gamers running dedicated game servers will appreciate the high single-thread scores, though the 6-core/12-thread layout limits how many concurrent players or game instances can be hosted before contention appears.

Power and Thermals

The 65 W TDP is the defining thermal characteristic of this part. Built on TSMC's 4 nm process with 8,315 million transistors in a 70.6 mm² die, the EPYC 4245P generates modest heat for a server processor. This implies a standard air-cooling tier is sufficient; no exotic liquid or high-end tower cooler is required to maintain sustained boost behavior. The low thermal envelope also makes the chip attractive for dense 1U servers and compact workstations where cooling headroom is limited. Benchmark results do not show any thermal throttling indicators in the data, and the 65 W class typically allows small, quiet cooling solutions in desktop-style AM5 boards.

Single-Thread vs Multi-Thread Behavior

The EPYC 4245P shows a pronounced split between single-thread and multi-thread performance. In Cinebench R23, the single-core score of 3,757 stands against a multi-core score of 26,618; the R20 results show 1,577 single-core versus 11,179 multi-core, and R15 shows 378 single-core versus 2,682 multi-core. This pattern indicates strong per-core efficiency — the Zen 5 architecture and 5.40 GHz boost clock deliver excellent responsiveness on single-threaded tasks, which is unusual for a server-oriented chip.

Passmark reinforces the picture: single-thread score of 4,603 versus a multithread score of 31,316. The multi-thread figure is respectable for a 6-core part, but the real standout is the single-thread result, which exceeds what older 8-core server chips typically manage. In practice, this means the 4245P excels in workloads that are latency-bound — API gateways, network packet processing, database query dispatch, and interactive sessions. For heavily parallel workloads like batch rendering or large-scale data processing, the 12 threads will be the limiting factor, and the chip will fall behind higher-core-count rivals despite its architectural efficiency.

The Passmark extended instructions score of 26,500 and physics score of 2,760 suggest that AVX-class and physics workloads scale reasonably, but the find-prime-numbers score of 195 is a weak point, indicating that certain integer-heavy loops do not benefit as much from the high clock speed. Overall, the data shows a processor that punches above its weight in single-thread scenarios and delivers competent, if not class-leading, multi-thread performance for its core count.

Platform and Compatibility

The EPYC 4245P uses AMD Socket AM5, which provides a clear upgrade path within the same platform family. It belongs to the EPYC 4005 series under the "Grado" codename, built on the Zen 5 architecture at a 4 nm process node from TSMC. Memory support is DDR5 in a dual-channel layout with 89.6 GB/s bandwidth, and ECC memory is supported — a critical feature for server deployments. The cache hierarchy consists of 80 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3 cache.

PCIe connectivity is Gen 5 with 24 lanes available from the CPU, which is sufficient for high-speed NVMe storage arrays and a single high-end GPU in workstation builds. The integrated Radeon Graphics adds display capability without a discrete card, and the part number is 100-000001555. Production status is Active, with a release date of 2025-05-12. The multiplier is locked, so platform tuning will focus on memory configuration and power management rather than overclocking. The 65 W TDP means standard AM5 motherboards with adequate VRM cooling will handle it without special provisions, and the server/workstation market segment designation indicates it is intended for always-on operation.

Benchmark Performance

The EPYC 4245P delivers an average benchmark score of 39,383, placing it at the 90th percentile of all CPUs tested. This is a strong showing for a 6-core part, driven primarily by exceptional single-thread performance and efficient Zen 5 execution. In Cinebench R23, the multi-core score of 26,618 and single-core score of 3,757 represent a well-balanced profile; the R20 scores of 11,179 multi-core and 1,577 single-core follow the same pattern, and the R15 scores of 2,682 multi-core and 378 single-core confirm consistency across benchmark generations.

Against its nearest rivals, the deltas are tight. The Ryzen 9 5900X leads by 0.2% with an average score of 39,453; the Core i7-13700F trails the EPYC by 0.7% with 39,095; the Ryzen 7 PRO 8845HS leads by 0.9% with 39,747; and the Xeon 6369P trails by 1% with 38,988. These margins are within noise for most real-world workloads, meaning the EPYC 4245P is competitively positioned against a mix of desktop, mobile, and server parts from both AMD and Intel.

The Passmark suite provides finer granularity. Data compression scores 340,354, indicating strong memory subsystem performance. Data encryption scores 18,444, which is adequate for AES-class workloads. Extended instructions score 26,500, floating-point math 58,045, and integer math 95,253 — the integer advantage over floating-point suggests the chip is better tuned for business logic, database operations, and general server code than for heavy scientific computing. The multithread score of 31,316 and physics score of 2,760 round out the profile, while the find-prime-numbers score of 195 is notably low, pointing to a weakness in certain tight-loop integer algorithms. Random string sorting at 41,253 reinforces the data-movement strengths. Overall, the benchmark data shows a processor that is a top-tier single-thread performer in its segment, a solid multi-thread worker for its core count, and a credible alternative to established desktop and server parts within a 1% performance band.
