Analysis: AMD EPYC 7702P vs AMD Ryzen 5 40
Head-to-Head Benchmarks
The benchmark comparison between the AMD Ryzen 5 40 and the AMD EPYC 7702P is not a close contest. Across every recorded test in the database, the EPYC 7702P posts a decisive victory. The head-to-head data shows four benchmark comparisons, and the EPYC wins all four. The Ryzen 5 40 records zero wins in this matchup.
In Cinebench R23 multi-core, the EPYC 7702P scores 52,308 against the Ryzen 5 40's 4,841. That is a delta of -90.7 percent, meaning the EPYC outperforms the Ryzen by nearly eleven times in this heavily threaded workload. The magnitude of this gap reflects the fundamental difference in core count: the EPYC packs 64 cores and 128 threads, while the Ryzen 5 40 offers 4 cores and 8 threads.
Single-core performance tells a different story in terms of margin, though the winner remains the same. In Cinebench R23 single-core, the EPYC 7702P scores 7,384, while the Ryzen 5 40 manages 1,150. The delta is -84.4 percent. Even with a significantly higher boost clock on the Ryzen (4.30 GHz versus 3.35 GHz), the EPYC's single-threaded score is over six times higher. This indicates that the EPYC's Zen 2 implementation in the Rome generation delivers substantially higher instructions per clock in this benchmark, or that the benchmark itself is not purely clock-bound.
Cinebench R15 multi-core shows a similar pattern. The EPYC 7702P scores 5,272, and the Ryzen 5 40 scores 790, a delta of -85 percent. In Cinebench R15 single-core, the EPYC posts 744 against the Ryzen's 165.5, a delta of -77.8 percent. The EPYC's advantage narrows in single-core relative to multi-core, but it remains overwhelming.
The database also records average benchmark scores for each processor. The Ryzen 5 40 has an average benchmark score of 15,882, while the EPYC 7702P sits at 15,130. Interestingly, this places the Ryzen slightly ahead on average, despite losing every head-to-head test. This is because the Ryzen's average includes its Passmark suite results, which are not part of the head-to-head comparison. The EPYC's average is drawn from a different set of tests, including Cinebench R20, which the Ryzen lacks.
Percentile rankings reinforce the competitive positioning. The Ryzen 5 40 sits at the 70th percentile among all CPUs in the database. The EPYC 7702P sits at the 69th percentile. The Ryzen ranks marginally higher in this metric, reflecting its strong single-threaded Passmark scores and the fact that its average is computed across a broader set of workloads.
The nearest rivals for each processor provide additional context. The Ryzen 5 40's closest competitor in the database is the AMD EPYC 75F3, which has an average score of 15,859, a delta of 0.1 percent. The Intel Core Ultra 5 134U sits just ahead with an average score of 15,910, a delta of -0.2 percent. For the EPYC 7702P, the nearest rival is the Intel Core i3-1315U with an average score of 15,022, a delta of 0.7 percent. The AMD EPYC 74F3 trails at 14,915, a delta of 1.4 percent.
Where Each One Wins
The use-case split is stark. The EPYC 7702P wins every multi-threaded workload in the head-to-head comparison. Its 64 cores and 128 threads dominate in Cinebench R15 multi-core, R23 multi-core, and by extension any heavily parallelized rendering, simulation, or server workload. The 256 MB of shared L3 cache, combined with eight-channel memory support and 204.8 GB/s memory bandwidth, positions it for data-center tasks where memory throughput and cache capacity are critical.
The Ryzen 5 40, despite losing all head-to-head tests, has strengths that appear in its broader benchmark profile. Its Passmark single-thread score is 2,477, and its Passmark data compression score is 141,533. These are not compared directly against the EPYC in the head-to-head table, but they indicate that the Ryzen is a capable mobile processor for everyday tasks, web browsing, and light productivity. Its integrated Radeon 610M graphics provide a complete platform solution, which the EPYC lacks entirely.
The Ryzen's power profile is another distinguishing factor. With a TDP of 15 watts, it is designed for low-power mobile devices. The EPYC 7702P has a TDP of 200 watts. The Ryzen's 6 nm process node from TSMC is more advanced than the EPYC's 7 nm node, contributing to its efficiency. The Ryzen also uses LPDDR5 memory, whereas the EPYC uses DDR4.
For workloads that fit within the Ryzen's 4 cores and 8 threads, the recorded data shows it can hold its own in single-threaded tasks relative to its compact size. Its boost clock of 4.30 GHz is the highest among the two processors, and its Passmark single-thread score of 2,477 suggests respectable per-core performance for a mobile part.
The EPYC's wins are not just quantitative; they are transformative. In Cinebench R23 multi-core, the EPYC's score of 52,308 is more than ten times the Ryzen's 4,841. No amount of clock speed or architectural efficiency on the Ryzen can close that gap. The EPYC's 3,800 million transistors and 74 mm² die size, while modest per-chiplet, combine across 64 cores to deliver massive throughput.
Architecture Differences
The two processors share the same Zen 2 architecture but diverge sharply in implementation. The Ryzen 5 40 uses the Mendocino codename and is built on a 6 nm process node at TSMC. The EPYC 7702P uses the Rome codename and is built on a 7 nm process node at TSMC. Both are fabricated by TSMC, but the Ryzen's smaller node gives it a density and efficiency advantage.
Core counts differ by an order of magnitude. The Ryzen 5 40 has 4 cores and 8 threads. The EPYC 7702P has 64 cores and 128 threads. This 16x core difference and 16x thread difference drive the benchmark results. The Ryzen's base clock is 2.80 GHz with a boost of 4.30 GHz. The EPYC's base clock is 2000.00 MHz (2.00 GHz) with a boost of 3.35 GHz. The Ryzen's higher clocks are a consequence of lower core counts and lower power targets.
Cache hierarchies are fundamentally different. The Ryzen 5 40 has 64 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3 cache. The EPYC 7702P has 96 KB of L1 per core, 512 KB of L2 per core, and a massive 256 MB of shared L3 cache. The EPYC's L3 cache is 64 times larger than the Ryzen's. This cache capacity is crucial for server workloads that repeatedly access large datasets.
Memory support reflects their target markets. The Ryzen 5 40 uses LPDDR5 memory on a dual-channel bus, providing 88.0 GB/s of bandwidth. The EPYC 7702P uses DDR4 memory on an eight-channel bus, providing 204.8 GB/s of bandwidth. The EPYC's bandwidth is more than double the Ryzen's. The EPYC also supports ECC memory, while the Ryzen does not.
The sockets and platforms are incompatible. The Ryzen 5 40 uses AMD Socket FT6, a mobile platform. The EPYC 7702P uses AMD Socket SP3, a server platform. The Ryzen includes integrated Radeon 610M graphics, while the EPYC has no integrated graphics. The Ryzen's PCIe implementation is Gen 3 with 4 lanes (CPU only), while the EPYC supports PCIe Gen 4.
Packaging and transistor counts differ. The EPYC 7702P contains 3,800 million transistors across its chiplet design, with a die size of 74 mm² per chiplet. The Ryzen 5 40 has a die size of 100 mm², but its transistor count is not recorded in the database. The EPYC's 64-core design requires multiple chiplets, whereas the Ryzen is a monolithic mobile part.
Release dates show a generational gap. The EPYC 7702P launched on August 6, 2019. The Ryzen 5 40 launched on September 30, 2025. The Ryzen is a much newer product, benefiting from a more advanced process node and newer memory technology. Despite this, the EPYC's massive core count and cache size overwhelm the Ryzen in every head-to-head benchmark.
The Verdict
The data is unambiguous. The AMD EPYC 7702P is the superior processor for any workload that can utilize more than 4 cores. In Cinebench R23 multi-core, it delivers 52,308 points, which is 90.7 percent ahead of the Ryzen 5 40's 4,841. For server, workstation, virtualization, database, and rendering workloads, the EPYC 7702P is the clear choice. Its 64 cores, 128 threads, 256 MB L3 cache, 204.8 GB/s memory bandwidth, and ECC support make it a data-center powerhouse.
The Ryzen 5 40 is a mobile processor designed for efficiency and portability. Its 15 watt TDP, 6 nm process, integrated Radeon 610M graphics, and LPDDR5 memory support make it suitable for thin-and-light laptops. It cannot compete with the EPYC in multi-threaded performance, and the benchmark data shows zero wins in head-to-head tests. However, its single-threaded Passmark score of 2,477 and its high boost clock of 4.30 GHz indicate reasonable per-core performance for everyday tasks.
The average benchmark scores complicate a simple verdict. The Ryzen 5 40 has an average benchmark score of 15,882, which is higher than the EPYC's 15,130. The Ryzen also holds a slightly higher percentile ranking at 70 versus 69. This is because the Ryzen's average includes Passmark tests that are not in the head-to-head comparison. The EPYC's average includes Cinebench R20 results, which are not recorded for the Ryzen. These averages reflect different test suites and should not be interpreted as a direct performance comparison.
For a user building a server or a workstation that requires massive parallel processing, the EPYC 7702P is the only rational choice from the data. For a user seeking a low-power mobile processor with integrated graphics, the Ryzen 5 40 is the appropriate selection. No single processor wins across all metrics in the database, but the head-to-head benchmarks decisively favor the EPYC.
