AMD EPYC 7702 vs AMD Ryzen 3 7335U Comparison

The AMD EPYC 7702 and AMD Ryzen 3 7335U represent opposite extremes of the processor spectrum: a 64-core server behemoth designed for massive parallel workloads versus a 4-core mobile chip built for efficiency and portability. The benchmark data confirms this chasm, with the EPYC 7702 winning all six head-to-head Cinebench tests by a landslide margin. However, both processors occupy the same 70th percentile in the database, a reminder that average scores blend vastly different workload characteristics. The EPYC 7702 is a Zen 2-based Rome part on AMD Socket SP3, while the Ryzen 3 7335U is a Zen 3+ Rembrandt-R mobile chip on AMD Socket FP7.

Head-to-Head Benchmarks

The EPYC 7702 dominates every single benchmark in the head-to-head comparison, with margins that are remarkably consistent across all tests. In Cinebench R15 multicore, the EPYC 7702 scores 5900 against the Ryzen 3 7335U's 1078, a delta of 447.3%. The single-core R15 test tells a similar story: 832 versus 152, a 447.4% advantage for the server chip. This consistency in delta percentages—hovering around 447% across every test—indicates that the performance gap is not workload-dependent but rather a fundamental scaling difference between the two architectures.

Moving to Cinebench R20, the pattern holds. The EPYC 7702 posts 24586 in multicore against 4495 for the Ryzen 3 7335U, a 447% difference. Single-core R20 shows 3470 versus 634, again 447.3%. The R23 results continue the trend with a multicore score of 58539 for the EPYC 7702 versus 10703 for the Ryzen 3 7335U, and single-core scores of 8264 versus 1511. Both R23 deltas sit at 446.9%. The near-identical percentage deltas across all six tests suggest that the EPYC 7702's advantage is purely a matter of raw compute resources, not architectural efficiency per clock.

The data shows the EPYC 7702 wins all six head-to-head benchmarks, with no wins for the Ryzen 3 7335U. The smallest delta is 446.9% in the R23 tests, and the largest is 447.4% in R15 single-core. This is an unusually narrow spread for a comparison spanning such different processor classes. For context, the EPYC 7702's average benchmark score is 16932, placing it near the AMD Ryzen 5 7235HS (16902, 0.2% delta) and Intel Core i5-1240U (16957, -0.1% delta). The Ryzen 3 7335U's average score is 16827, sitting close to the Intel Core i3-12100E (16853, -0.2% delta) and Intel Core Ultra 5 115U (16753, 0.4% delta). These rival comparisons reveal that despite the EPYC 7702's massive Cinebench wins, its overall average is only 0.6% higher than the Ryzen 3 7335U's average—proof of how differently these chips perform across varied workloads.

A: The EPYC 7702 has a TDP of 200 watts, while the Ryzen 3 7335U has a TDP of 28 watts. The Ryzen 3 7335U consumes approximately 14% of the power of the EPYC 7702, yet delivers about 99.4% of its average benchmark score.

Q: Are there any PassMark benchmarks for the EPYC 7702?

A: No. The FACT PACK lists PassMark benchmarks only for the Ryzen 3 7335U, including data compression (146309), data encryption (9335), and floating point math (24298). The EPYC 7702's benchmark data is limited to Cinebench R15, R20, and R23 tests.

Architecture Differences

The two processors come from fundamentally different architectural generations. The EPYC 7702 uses Zen 2 architecture under the codename "Rome," belonging to the EPYC 7002 series. The Ryzen 3 7335U uses Zen 3+ architecture with the codename "Rembrandt-R," part of the 7000 series. This generational gap means the Ryzen 3 7335U benefits from architectural improvements in IPC and power efficiency, though the EPYC 7702's overwhelming core count negates this in most workloads.

The process nodes differ significantly: the EPYC 7702 is built on a 7 nm process with 3,800 million transistors on a 74 mm² die, while the Ryzen 3 7335U uses a 6 nm process with a 208 mm² die size. Both are manufactured by TSMC. The smaller die size of the EPYC 7702 relative to its transistor count is notable, though the Ryzen 3 7335U's larger die area likely accommodates the integrated Radeon 660M graphics, which the EPYC 7702 lacks entirely.

Cache hierarchies are dramatically different. The EPYC 7702 provides 96 KB of L1 cache per core and 512 KB of L2 per core, matching the Ryzen 3 7335U's L2 configuration but with more L1 per core (96 KB versus 64 KB). The L3 cache is where the gap becomes enormous: the EPYC 7702 has 256 MB shared L3, while the Ryzen 3 7335U has only 8 MB shared. This 32x difference in L3 capacity directly supports the EPYC 7702's server workload ambitions.

Memory support also diverges. The EPYC 7702 uses DDR4 memory with an eight-channel bus and 204.8 GB/s bandwidth. The Ryzen 3 7335U uses DDR5 with a dual-channel bus and 76.8 GB/s bandwidth. Both support ECC memory, but the EPYC 7702's memory bandwidth is 2.7x higher. PCIe connectivity is Gen 4 for both, though the Ryzen 3 7335U specifies 20 lanes (CPU only), while the EPYC 7702's lane count is not specified in the data.

Specification Differences

The core and thread counts present the most obvious difference: the EPYC 7702 has 64 cores and 128 threads, while the Ryzen 3 7335U has 4 cores and 8 threads. Clock speeds also invert the expected relationship—the Ryzen 3 7335U has a higher base clock (3.00 GHz versus 2.00 GHz) and a higher boost clock (4.30 GHz versus 3.35 GHz), yet still loses all benchmark tests.

The TDP difference is substantial: 200 watts for the EPYC 7702 versus 28 watts for the Ryzen 3 7335U. This 7x power gap defines their respective market segments. The EPYC 7702 targets server/workstation deployments with AMD Socket SP3, while the Ryzen 3 7335U is designed for mobile platforms with AMD Socket FP7. The EPYC 7702 is not multiplier unlocked, and neither is the Ryzen 3 7335U.

Release dates show the EPYC 7702 launched on 2019-08-06, while the Ryzen 3 7335U arrived on 2023-01-03. The EPYC 7702's part number is 100-000000038, while the Ryzen 3 7335U has two part numbers: 100-000000537 (FP7) and 100-000000549 (FP7r2). The Ryzen 3 7335U includes integrated Radeon 660M graphics; the EPYC 7702 has no integrated graphics. Both are active production parts.

The Verdict

The data points to a clear conclusion: the AMD EPYC 7702 is the overwhelming choice for multi-threaded server and workstation workloads. Its 64 cores and 128 threads deliver Cinebench R23 multicore performance of 58539, which is 446.9% ahead of the Ryzen 3 7335U. The 256 MB of L3 cache, eight-channel DDR4 memory with 204.8 GB/s bandwidth, and 200-watt TDP all support this positioning. The EPYC 7702 also wins single-core tests despite lower clock speeds, suggesting its Zen 2 architecture at 3.35 GHz boost outperforms the Ryzen 3 7335U's Zen 3+ at 4.30 GHz boost in the specific Cinebench workloads tested.

The AMD Ryzen 3 7335U is the sensible choice for mobile computing where power efficiency and portability matter. Its 28-watt TDP is just 14% of the EPYC 7702's power draw, while its average benchmark score of 16827 is 99.4% of the EPYC 7702's 16932. The Ryzen 3 7335U includes integrated Radeon 660M graphics, DDR5 memory support, and a higher boost clock, making it suitable for thin-and-light laptops. However, its 4 cores and 8 threads limit it to lighter workloads, and its 8 MB L3 cache is a fraction of the EPYC 7702's 256 MB.

For users who need maximum parallel compute capability—such as virtualization, scientific simulation, or database workloads—the EPYC 7702 is the only viable option between these two. For users who need an efficient processor for everyday mobile tasks, the Ryzen 3 7335U offers comparable average performance at a fraction of the power cost. The 0.6% difference in average benchmark scores is negligible, but the 16x core count difference and 7x TDP difference illustrate that these processors serve entirely different purposes. The EPYC 7702 wins every measured benchmark, but the Ryzen 3 7335U wins on efficiency and portability, making the choice dependent entirely on the deployment environment.
