AMD EPYC 7252 vs AMD Ryzen 7 5800HS Comparison

The AMD Ryzen 7 5800HS and AMD EPYC 7252 are both 8-core, 16-thread processors, yet they target opposite ends of the computing spectrum: one is a low-power mobile part, the other a high-TDP server workhorse. Despite their vastly different platforms, the benchmark data reveals a remarkably close contest, with the Ryzen 7 5800HS taking a narrow but decisive lead across every single Cinebench test.

Head-to-Head Benchmarks

The data is unambiguous: the Ryzen 7 5800HS wins all six head-to-head comparisons, though by margins that are almost statistically insignificant. In Cinebench R15 multi-core, the Ryzen 7 5800HS scores 1682 against the EPYC 7252's 1662, a delta of just 1.2%. The single-core test in R15 tells a similar story, with the Ryzen 7 5800HS at 237 points versus 234 points for the EPYC 7252, a 1.3% advantage.

Moving to Cinebench R20, the pattern holds. The Ryzen 7 5800HS posts 7009 points in multi-core, while the EPYC 7252 manages 6929, again a 1.2% gap. In single-core R20, the scores are 989 and 978 respectively, with the Ryzen 7 5800HS ahead by 1.1%. The most recent Cinebench R23 test shows the same consistency: the Ryzen 7 5800HS scores 16690 in multi-core versus 16499 for the EPYC 7252, a 1.2% lead, and 2356 versus 2329 in single-core, also a 1.2% margin.

These margins are razor-thin, but they are uniform. The Ryzen 7 5800HS never loses a single benchmark, and its average benchmark score of 4827 sits above the EPYC 7252's 4772. In terms of overall percentile ranking, both processors land at the 59th percentile of all CPUs, indicating they are equivalent in the broader performance hierarchy. The Ryzen 7 5800HS's closest rival is the AMD Ryzen 7 4700GE with an average score of 4836 (a -0.2% delta), while the EPYC 7252's nearest competitor is the Intel Xeon W-1290E at 4775 (a -0.1% delta). The performance takeaway is that these chips are effectively peers in raw compute, despite their entirely different design goals.

Architecture Differences

The architectural gap between these two chips is far wider than their benchmark scores suggest. The Ryzen 7 5800HS is built on the Zen 3 architecture, codenamed Cezanne, and belongs to the 5000 series. It is fabricated on a 7 nm process at TSMC, packing 10,700 million transistors into a 180 mm² die. In contrast, the EPYC 7252 uses the older Zen 2 architecture, codenamed Rome, from the EPYC 7002 series. It also uses a 7 nm TSMC process, but the chip is composed of two dies, each measuring 74 mm², for a combined transistor count of 7,600 million.

The cache configurations differ significantly. Both share the same 64 KB of L1 and 512 KB of L2 per core. However, the Ryzen 7 5800HS has a single 16 MB shared L3 cache, while the EPYC 7252 features 32 MB of L3 per die, totaling 64 MB. This gives the server chip four times the total L3 capacity, a design choice aimed at handling large server workloads with higher memory locality demands.

Platform support is where the two diverge completely. The Ryzen 7 5800HS is a mobile chip with a 35 W TDP, designed for AMD Socket FP6. It supports dual-channel DDR4 memory with a bandwidth of 68.3 GB/s and does not support ECC memory. It also includes integrated Radeon Vega 8 graphics, which the EPYC 7252 lacks entirely. The EPYC 7252, on the other hand, is a server processor with a 120 W TDP on AMD Socket SP3. It supports eight-channel DDR4 memory, yielding 85.3 GB/s of bandwidth, and fully supports ECC memory. The EPYC 7252 also offers PCIe Gen 4 with 128 lanes (CPU only), whereas the Ryzen 7 5800HS is limited to PCIe Gen 3.

Where Each One Wins

The Ryzen 7 5800HS wins in all six benchmark tests, making it the clear victor in raw single-threaded and multi-threaded Cinebench performance. Its boost clock of 4.40 GHz, compared to the EPYC 7252's 3.20 GHz, is the primary driver of its higher single-core scores. For workloads that are latency-sensitive or lightly threaded, the Ryzen 7 5800HS has a measurable, albeit small, edge. The data shows it is also the more efficient performer, achieving higher scores at a 35 W TDP versus the EPYC's 120 W.

The EPYC 7252's wins are not in benchmark scores but in platform capabilities. Its eight-channel memory bus and 85.3 GB/s bandwidth, alongside ECC support, make it suited for memory-intensive server tasks where data integrity and throughput matter more than clock speed. The 64 MB of total L3 cache is another advantage for workloads that repeatedly access large datasets, as it reduces the need to go to system memory. The EPYC 7252's 128 PCIe Gen 4 lanes provide far more expansion headroom for storage and networking controllers in a server chassis.

For a mobile user, the Ryzen 7 5800HS is the obvious choice due to its integrated graphics and low power envelope. For a server administrator, the EPYC 7252's memory bandwidth, ECC support, and expansion capabilities are non-negotiable features that outweigh its slight performance deficit in Cinebench. The benchmark data indicates that for pure CPU compute, the Ryzen 7 5800HS is faster, but the EPYC 7252 is designed for a different class of workload entirely.

Specification Differences

The two processors differ on nearly every specification except for core count, thread count, L1/L2 cache sizes, manufacturer, and process node. The core and thread counts are identical at 8 and 16, respectively, and both use a 7 nm TSMC process. The L1 cache is 64 KB per core and L2 is 512 KB per core on both.
