AMD EPYC 9334 vs AMD Ryzen 3 7335U Comparison

Head-to-Head Benchmarks

The recorded data presents a matchup with an unusually clear outcome. Across all six head-to-head Cinebench tests, the AMD EPYC 9334 records a victory over the AMD Ryzen 3 7335U, with no benchmark win going the other way. The dominance is not merely qualitative; the deltas are consistently massive, hovering around 415% in every discipline.

In Cinebench R15 multicore, the EPYC 9334 scores 5,555 against the Ryzen 3 7335U's 1,078, a 415.3% advantage. The single-core R15 result follows the same pattern: 784 versus 152, a 415.8% delta. Moving to Cinebench R20, the multicore test shows 23,146 against 4,495, a 414.9% gap, while the single-core test records 3,267 versus 634, a 415.3% difference. Cinebench R23 multicore delivers 55,110 against 10,703, a 414.9% lead, and the R23 single-core test closes the set at 7,780 versus 1,511, again a 414.9% delta.

What stands out is the consistency of the percentage margins. Whether the workload is single-threaded or fully parallel, the EPYC 9334 maintains roughly the same proportional advantage. This suggests the gap is not merely about core count, which would inflate multicore scores, but also about per-core throughput. The single-core deltas of roughly 415% are just as large as the multicore deltas, indicating that the EPYC 9334's Zen 4 architecture at 5 nm is delivering far more work per clock than the Ryzen 3 7335U's Zen 3+ at 6 nm. The Ryzen 3 7335U does have a higher boost clock on paper at 4.30 GHz versus 3.90 GHz, yet it still loses single-core tests by a factor of more than five, which points to a fundamental architectural gulf rather than a simple clock frequency issue.

The average benchmark scores in the database are closer than the head-to-head tests suggest, but this is a quirk of the averaging methodology. The EPYC 9334 has an average benchmark score of 15,940 across its Cinebench results, while the Ryzen 3 7335U records 16,827, a figure lifted by additional PassMark tests that the EPYC 9334 does not have in its database entry. The nearest rival data tells a similar story: the EPYC 9334 sits within 0.2% of the Intel Core Ultra 5 134U (15,910) and 0.4% of the AMD Ryzen 5 40 (15,882), while the Ryzen 3 7335U is 0.2% behind the Intel Core i3-12100E (16,853) and 0.4% behind the AMD Ryzen 5 7235HS (16,902). Both processors occupy the 70th percentile among all CPUs in the database, but that percentile ranking masks the fact that the EPYC 9334 achieves its standing with far fewer benchmark entries, all of which are heavily weighted toward multicore rendering.

Where Each One Wins

The use-case split is stark. The EPYC 9334 wins every benchmark category recorded in the head-to-head set, meaning there is no measured workload where the Ryzen 3 7335U comes out ahead. The EPYC 9334's 32 cores and 64 threads, combined with 128 MB of shared L3 cache, make it a processor built for sustained parallel workloads. Its 210 W TDP and twelve-channel DDR5 memory bus with 460.8 GB/s of bandwidth further reinforce its positioning as a server and workstation part. The Ryzen 3 7335U, by contrast, is a 28 W mobile processor with 4 cores and 8 threads, 8 MB of shared L3 cache, a dual-channel DDR5 bus at 76.8 GB/s, and integrated Radeon 660M graphics.

For tasks like video rendering, scientific simulation, database processing, or any workload that scales across cores, the EPYC 9334 is the clear choice based on the Cinebench R15, R20, and R23 multicore results. The Ryzen 3 7335U does have its own strengths, but they are not visible in the head-to-head benchmark set. Its PassMark results, which are not part of the head-to-head comparison, show a single-thread score of 3,053 and a multithread score of 12,592, along with data compression at 146,309, data encryption at 9,335, extended instructions at 10,314, floating point math at 24,298, integer math at 42,493, physics at 647, and random string sorting at 15,361. These are respectable numbers for a mobile chip, but they do not appear in the direct comparison, and the Ryzen 3 7335U's 4.30 GHz boost clock does not translate into a win against the EPYC 9334 in any single-core test.

The mobile segment is where the Ryzen 3 7335U makes sense. Its 28 W TDP, FP7 socket, and integrated Radeon 660M graphics indicate a processor designed for laptops where power draw and heat are primary constraints. The EPYC 9334, with its SP5 socket and 210 W TDP, is not portable in any practical sense. The data shows a clean split by form factor: the EPYC 9334 wins on raw performance, while the Ryzen 3 7335U is the only one of the two that could operate in a battery-powered chassis.

Architecture Differences

The two processors come from different generations of AMD's design philosophy. The EPYC 9334 uses the Zen 4 architecture with the Genoa codename, built on a 5 nm process at TSMC. It packs 32 cores and 64 threads across a design that includes 52,560 million transistors spread over a die size of 4x 72 mm². The Ryzen 3 7335U uses the Zen 3+ architecture with the Rembrandt-R codename, built on a 6 nm process, also at TSMC, with a die size of 208 mm². The transistor count for the Ryzen 3 7335U is not recorded in the database.

Cache hierarchies differ significantly. The EPYC 9334 has 64 KB of L1 per core, 1 MB of L2 per core, and 128 MB of shared L3. The Ryzen 3 7335U also has 64 KB of L1 per core, but its L2 is halved to 512 KB per core, and its shared L3 is just 8 MB. That 16x difference in L3 capacity is a major factor in the EPYC 9334's multicore advantage, as more data can reside on-die without hitting the memory subsystem.

Memory support is another dividing line. Both processors support DDR5, but the EPYC 9334 uses a twelve-channel memory bus with 460.8 GB/s of bandwidth, while the Ryzen 3 7335U uses a dual-channel bus with 76.8 GB/s. Both support ECC memory. PCIe connectivity also differs: the EPYC 9334 provides Gen 5 with 128 lanes (CPU only), while the Ryzen 3 7335U provides Gen 4 with 20 lanes (CPU only). The EPYC 9334 has no integrated graphics, whereas the Ryzen 3 7335U includes a Radeon 660M iGPU.

The sockets reflect their respective markets: the EPYC 9334 uses AMD Socket SP5, a server platform, while the Ryzen 3 7335U uses AMD Socket FP7, a mobile platform. Neither processor has an unlocked multiplier. The EPYC 9334 launched on 2022-11-09 with a launch MSRP of $2990, while the Ryzen 3 7335U launched on 2023-01-03 with no MSRP recorded. The production status for both is listed as active.

The Verdict

The data points to two processors with almost no overlap in intended use. The AMD EPYC 9334 is a 32-core, 64-thread server and workstation part with a 210 W TDP, twelve-channel DDR5 memory, 128 MB of L3 cache, and 128 PCIe Gen 5 lanes. It wins every head-to-head benchmark against the Ryzen 3 7335U by margins of roughly 415%, and its 5 nm Zen 4 architecture delivers superior single-core throughput despite a lower boost clock. The Ryzen 3 7335U is a 28 W mobile processor with 4 cores, 8 threads, 8 MB of L3, and integrated Radeon 660M graphics, built on a 6 nm Zen 3+ process. Its strengths appear only outside the direct comparison, in PassMark tests where it records a single-thread score of 3,053 and a multithread score of 12,592, but those numbers do not translate into wins against the EPYC 9334.

Who should pick which? The answer comes straight from the recorded data. Anyone building a server or workstation that prioritizes raw multicore rendering, memory bandwidth, or PCIe lane count should choose the EPYC 9334, which delivers 55,110 in Cinebench R23 multicore and 23,146 in R20 multicore. Anyone designing a laptop or other power-constrained mobile system should choose the Ryzen 3 7335U, which is the only one of the two with a mobile socket, integrated graphics, and a 28 W TDP. There is no scenario in the benchmark data where the Ryzen 3 7335U outperforms the EPYC 9334, but there is also no scenario where the EPYC 9334 could realistically be installed in a mobile chassis. The verdict is not about which processor is better in absolute terms, but which fits the platform. For server workloads, the EPYC 9334 is the clear pick. For mobile workloads, the Ryzen 3 7335U is the only viable option between the two.
