AMD EPYC 7702P vs AMD Ryzen 5 5500U Comparison

Head-to-Head Benchmarks

The benchmark data paints an unambiguous picture: the AMD EPYC 7702P wins every single head-to-head comparison against the AMD Ryzen 5 5500U. In Cinebench R15 multi-core, the EPYC scores 5,272 versus the Ryzen’s 1,247, a delta of 322.8%. The single-core result is similarly lopsided: 744 versus 177, a 320.3% advantage. The gap widens further in Cinebench R23 multi-core, where the EPYC’s 52,308 crushes the Ryzen’s 7,186, producing a staggering 627.9% delta. Even in R23 single-core, the EPYC’s 7,384 outpaces the Ryzen’s 1,172 by 530%.

These are not marginal differences; they represent entirely different performance classes. The EPYC’s multi-core score is over seven times higher in R23, while its single-core lead exceeds fivefold. The Ryzen 5 5500U never reaches even 20% of the EPYC’s output in any shared benchmark. For context, the EPYC 7702P sits at the 69th percentile among all CPUs, with an average benchmark score of 15,130, placing it near rivals like the Intel Core i3-1315U (15,022, 0.7% behind) and the Intel Core 5 211TE (15,370, 1.6% ahead). The Ryzen 5 5500U also lands at the 69th percentile, but with a lower average score of 14,589, putting it in company with the AMD EPYC 7473X (14,574, 0.1% behind) and the Intel Core i5-9600K (14,605, 0.1% ahead).

The head-to-head table shows four wins for the EPYC and zero for the Ryzen. There is no benchmark in the shared set where the mobile chip claws back ground. The closest margin is Cinebench R15 single-core at 320.3%, which is still a decisive defeat. Every metric—multi-threaded rendering, single-threaded rendering, and both generations of Cinebench—favors the server processor by a wide margin.

The Verdict

From the data alone, the choice is straightforward for workloads that demand raw compute throughput. The AMD EPYC 7702P is the superior processor in every measured category, with multi-core leads that approach or exceed 600%. Any task that scales across cores—rendering, scientific computing, virtualization, database workloads—will see massive gains on the EPYC. Its 64 cores and 128 threads provide a parallel-processing capacity that the Ryzen 5 5500U’s 6 cores and 12 threads cannot approach. The EPYC’s Cinebench R23 multi-core score of 52,308 versus 7,186 is not a contest; it is a demonstration of architectural scale.

The Ryzen 5 5500U, however, is not without its own merits, though they do not appear in the head-to-head benchmarks. It carries integrated Radeon Graphics with 448 shader processors, a feature the EPYC lacks entirely. For a compact mobile system where discrete graphics are impractical, that integrated GPU is essential. The Ryzen also draws far less power—15W versus 200W—making it suitable for thin-and-light laptops, while the EPYC demands server-grade cooling and power delivery. The EPYC uses an AMD Socket SP3 platform, while the Ryzen uses Socket FP6, meaning they are not interchangeable. The EPYC targets server racks; the Ryzen targets portable PCs.

For a buyer choosing between these two, the decision hinges on the platform, not just the chip. If the workload is server-side and multi-threaded, the EPYC is the only rational pick. If the need is a mobile workstation or ultrabook with light to moderate compute, the Ryzen’s lower power envelope and integrated graphics make it viable, but its benchmark scores are dramatically lower. There is no scenario in this data where the Ryzen outperforms the EPYC on compute; the only reasons to choose it are power, size, and integrated graphics.

Architecture Differences

The two processors share a common foundation—both are built on AMD’s Zen 2 architecture and fabricated on TSMC’s 7 nm process—but diverge sharply in scale and implementation. The EPYC 7702P, part of the EPYC 7002 series with the codename Rome, packs 64 cores and 128 threads, with a base clock of 2.00 GHz and a boost clock of 3.35 GHz. The Ryzen 5 5500U, from the 5000 series with the codename Lucienne, offers just 6 cores and 12 threads, but runs at a higher base clock of 2.10 GHz and boosts to 4.00 GHz. The higher boost on the Ryzen does little to close the single-core gap, as the EPYC’s 3.35 GHz still delivers 530% more R23 single-core performance.

Cache hierarchies differ enormously. The EPYC provides 96 KB of L1 per core, 512 KB of L2 per core, and a massive 256 MB of shared L3 cache. The Ryzen has 64 KB of L1 per core, 512 KB of L2 per core, and only 8 MB of shared L3. That 32x difference in L3 capacity is a primary driver of the EPYC’s multi-threaded dominance, especially in cache-sensitive server workloads. The transistor counts also reflect the scale disparity: the EPYC uses 3,800 million transistors on a 74 mm² die, while the Ryzen uses 9,800 million on a 156 mm² die—the latter includes integrated graphics and a smaller core count but a larger physical footprint.

Memory support is another major differentiator. The EPYC supports DDR4 across an eight-channel memory bus, yielding 204.8 GB/s of bandwidth, and includes ECC memory support. The Ryzen supports DDR4 on a dual-channel bus, delivering 51.2 GB/s, with no ECC. For memory-bound server workloads, the EPYC’s fourfold bandwidth advantage is critical. PCIe connectivity also differs: the EPYC offers Gen 4, while the Ryzen provides Gen 3 with 12 lanes from the CPU. The EPYC’s socket is SP3, a server platform with multi-socket capabilities implicit in the EPYC line, while the Ryzen’s FP6 is a mobile BGA socket.

The EPYC has no integrated graphics, relying on a discrete GPU or a server board’s BMC. The Ryzen integrates Radeon Graphics with 448 shader processors, making it a complete system-on-chip for laptops. The EPYC’s TDP is 200W, versus 15W for the Ryzen—a 13x difference that dictates cooling and power delivery requirements. Both are currently in active production, with the EPYC released in August 2019 and the Ryzen in January 2021. Neither has an unlocked multiplier.

Where Each One Wins

The AMD EPYC 7702P wins in every compute benchmark measured, but its strengths are most pronounced in multi-threaded workloads. Cinebench R23 multi-core shows a 627.9% lead, and R15 multi-core shows a 322.8% lead. These results indicate that any application that can utilize more than a handful of threads will see exponential gains on the EPYC. The 256 MB of shared L3 cache and 204.8 GB/s of memory bandwidth make it ideal for server-side databases, virtual machine hosts, and high-performance computing tasks where data residency and memory throughput are paramount. The EPYC’s eight-channel memory bus and ECC support further cement its position for reliability-critical enterprise workloads. Its 64 cores and 128 threads provide headroom for massive parallelization that the Ryzen cannot match.

The AMD Ryzen 5 5500U wins in no head-to-head benchmark, but its design goals lie elsewhere. Its 15W TDP makes it suitable for fanless or low-noise mobile devices, and its integrated Radeon Graphics (448 shader processors) eliminate the need for a separate GPU in basic desktop or laptop configurations. The Ryzen’s 4.00 GHz boost clock gives it a nominal frequency advantage, though it does not translate into a single-core win in the data. For users who need a compact, low-power system with acceptable compute for everyday tasks, the Ryzen is the only viable option between the two—the EPYC’s 200W TDP and SP3 socket preclude any portable use. The Ryzen’s 9,800 million transistors on a 156 mm² die reflect a more integrated design, but that integration comes at the cost of raw performance.

In summary, the EPYC 7702P is the clear winner for server and workstation compute, with dominant multi-core and single-core scores. The Ryzen 5 5500U is the winner for mobile form factors and power-constrained environments, where its lower TDP and integrated graphics are decisive, despite its substantial performance deficit. The data does not support any scenario where the Ryzen outperforms the EPYC on compute, but the platform differences—socket, power, graphics, and memory channels—dictate which processor belongs in which system.
