AMD EPYC 4245P vs AMD Ryzen 7 250 Comparison

FAQ

Q: Which processor has the higher boost clock?

A: The AMD EPYC 4245P boosts to 5.40 GHz, while the AMD Ryzen 7 250 reaches 5.10 GHz. This 0.30 GHz advantage contributes heavily to the EPYC's single-core wins.

Q: Is the EPYC 4245P an unlocked multiplier part?

A: No. Both the EPYC 4245P and the Ryzen 7 250 have locked multipliers, so overclocking via multiplier adjustment is not supported on either.

Q: Does the Ryzen 7 250 support ECC memory?

A: No. ECC memory is supported on the EPYC 4245P, but the Ryzen 7 250 does not support ECC. If you need error-correcting memory, that is a decisive factor.

Q: What is the memory bandwidth of each processor?

A: Both support dual-channel DDR5 and show the same recorded memory bandwidth of 89.6 GB/s. Memory bandwidth is not a point of differentiation here.

Q: Which chip has more PCIe lanes?

A: The EPYC 4245P offers 24 CPU-only lanes of PCIe Gen 5, while the Ryzen 7 250 provides 20 lanes of PCIe Gen 4. The EPYC has both more lanes and a newer PCIe generation.

Q: How do the average benchmark scores compare?

A: The EPYC 4245P averages 39215 across the benchmark suite, while the Ryzen 7 250 averages 38221. Both sit at the 86th percentile among all CPUs, but the EPYC holds a lead of roughly 2.6% in average score.

The Verdict

The data is unambiguous: in every single recorded head-to-head benchmark, the AMD EPYC 4245P wins. Out of 15 comparisons, the EPYC takes all 15. The Ryzen 7 250 has zero wins. If you are choosing between these two, the EPYC 4245P is the stronger performer across the board.

That said, the choice is not just about raw scores. The EPYC 4245P targets the server and workstation segment, with ECC memory support, PCIe Gen 5, and a 65 W TDP. The Ryzen 7 250 is a mobile part, built for the FP8 socket with a 28 W TDP. The Ryzen 7 250 does have 8 cores versus the EPYC's 6 cores, but the EPYC's higher clocks and Zen 5 architecture overcome that core deficit in every tested workload.

For a builder assembling a workstation or server on Socket AM5, the EPYC 4245P is the obvious pick. For a mobile or low-power system, the Ryzen 7 250 fits that socket, but it will not match the EPYC's performance. The Ryzen 7 250's integrated Radeon 780M graphics are more capable than the EPYC's Radeon Graphics, which matters if you need stronger integrated visuals. But for compute-heavy tasks, the EPYC 4245P dominates.

Head-to-Head Benchmarks

The biggest single-core gap appears in Cinebench R23 single-core. The EPYC 4245P scores 3757 against the Ryzen 7 250's 1715, a 119.1% delta. That is more than double the score. The Cinebench R15 single-core test shows a similar pattern: 378 versus 269, a 40.5% delta. The EPYC's 5.40 GHz boost clock and Zen 5 cores clearly pay off in single-threaded work.

Multi-core results also favor the EPYC, though the margins vary. In Cinebench R23 multi-core, the EPYC scores 26618 versus 14676, an 81.4% delta. The Ryzen 7 250 does have two more cores (8 versus 6), but the EPYC's higher clocks and newer architecture still deliver a massive win. Cinebench R15 multi-core shows a smaller but still clear 16.5% delta: 2682 versus 2302.

PassMark workloads tell the same story. The largest delta is in find prime numbers, where the EPYC scores 193 versus 73, a 164.4% advantage. Physics also shows a huge gap: 2637 versus 1147, a 129.9% delta. Single-thread PassMark scores favor the EPYC by 24.4%: 4575 versus 3678.

Smaller wins still matter. Integer math sees the EPYC ahead by 3.9% (95120 versus 91565). Floating point math is an 8.8% EPYC win (57965 versus 53285). Data encryption is close at 4.6% (18466 versus 17661). Data compression shows a 12.9% EPYC edge (339408 versus 300708). Extended instructions favor the EPYC by 22.8% (26547 versus 21613). Random string sorting is an 11.3% EPYC win (39916 versus 35861). Multithread PassMark shows a 23.8% EPYC lead (31063 versus 25089).

The pattern holds consistently: the EPYC 4245P beats the Ryzen 7 250 in every recorded workload, with deltas ranging from 3.9% to 164.4%.

Specification Differences

The core counts differ: the EPYC 4245P has 6 cores and 12 threads, while the Ryzen 7 250 has 8 cores and 16 threads. Base clocks differ as well: 3.90 GHz for the EPYC versus 3.30 GHz for the Ryzen 7 250. Boost clocks are 5.40 GHz and 5.10 GHz, respectively.

TDP is a major differentiator. The EPYC runs at 65 W, while the Ryzen 7 250 draws only 28 W. That makes the Ryzen 7 250 a much lower-power part, suitable for mobile designs.

The sockets are different: the EPYC uses AMD Socket AM5, while the Ryzen 7 250 uses AMD Socket FP8. These are not interchangeable. The EPYC is a server and workstation part; the Ryzen 7 250 is a mobile part.

Memory support differs on ECC: the EPYC supports ECC, the Ryzen 7 250 does not. Both use dual-channel DDR5 with the same 89.6 GB/s bandwidth.

PCIe capabilities favor the EPYC: Gen 5 with 24 CPU-only lanes versus Gen 4 with 20 lanes on the Ryzen 7 250.

Integrated graphics differ. The EPYC has Radeon Graphics, while the Ryzen 7 250 has the Radeon 780M. The 780M is a more capable integrated GPU, which is worth noting for systems without a discrete card.

Release dates and pricing also differ. The EPYC launched on May 12, 2025 with a launch MSRP of $239. The Ryzen 7 250 launched on January 5, 2025, and no MSRP is recorded for it.

Architecture Differences

The EPYC 4245P is built on Zen 5 architecture, codenamed Grado, from the EPYC 4005 series. The Ryzen 7 250 uses Zen 4 architecture, codenamed Hawk Point. Both are fabricated on a 4 nm process at TSMC, so the process node is identical.

Die size and transistor counts differ significantly. The EPYC has 8,315 million transistors on a 70.6 mm² die. The Ryzen 7 250 packs 25,000 million transistors on a 178 mm² die. The Ryzen 7 250's larger die reflects its integrated Radeon 780M graphics and additional cores.

Cache layouts differ per core. The EPYC provides 80 KB of L1 per core and 1 MB of L2 per core, with 32 MB of shared L3. The Ryzen 7 250 provides 64 KB of L1 per core and 1 MB of L2 per core, with 16 MB of shared L3. The EPYC has twice the shared L3 cache, which helps in workloads that benefit from larger pooled cache.

Neither part features 3D V-Cache, and both have locked multipliers. The EPYC is part of the EPYC (Zen 5, Grado) generation, while the Ryzen 7 250 belongs to the Ryzen 7 (Zen 4, Hawk Point) generation.

The architecture differences explain much of the performance gap: Zen 5's IPC advantage over Zen 4, combined with higher clocks on the EPYC, produces the consistent wins seen in the benchmarks. The Ryzen 7 250's extra cores cannot compensate for the architectural and clock disadvantages.

Where Each One Wins

The EPYC 4245P wins in every benchmark category recorded. There is no workload in the data where the Ryzen 7 250 comes out ahead. If you need maximum single-thread performance, the EPYC delivers with a 119.1% lead in Cinebench R23 single-core and a 40.5% lead in Cinebench R15 single-core. For multi-threaded rendering, the EPYC leads by 81.4% in Cinebench R23 multi-core.

For server or workstation use, the EPYC is the clear choice. It supports ECC memory, offers PCIe Gen 5 with 24 lanes, and runs on the AM5 socket. The 65 W TDP is reasonable for a workstation part, and the 86th percentile standing among all CPUs confirms strong overall performance.

The Ryzen 7 250 does have some redeeming qualities, though they are not reflected in the compute benchmarks. It draws only 28 W, making it far more power-efficient. Its 8 cores and 16 threads provide more parallel hardware, even if the EPYC still wins in multithreaded tests due to higher clocks. The Radeon 780M integrated graphics are a step up from the EPYC's Radeon Graphics, which matters for light gaming or media tasks without a discrete GPU. The FP8 socket targets mobile designs, so this chip belongs in laptops and compact systems.

In short: for raw compute, choose the EPYC 4245P. For a low-power mobile platform with better integrated graphics, the Ryzen 7 250 has a role, but it will not match the EPYC's benchmark results. The data shows a complete sweep: 15 wins for the EPYC, 0 for the Ryzen 7 250.
