AMD EPYC 7573X vs AMD Ryzen 3 7335U Comparison

Head-to-Head Benchmarks

The recorded data for this comparison is unusually one-sided. Across all six Cinebench head-to-head tests, the AMD EPYC 7573X wins every single matchup, and the margins are remarkably consistent, hovering in a narrow band between 451.4% and 452.0% faster than the AMD Ryzen 3 7335U. In Cinebench R23 multi-core, the EPYC 7573X scores 59,017 against the Ryzen 3 7335U's 10,703, a 451.4% advantage. The single-core results tell the same story: 8,331 versus 1,511 in R23, again 451.4% ahead.

The pattern holds across older Cinebench versions as well. In Cinebench R20 multi-core, the EPYC 7573X records 24,787 while the Ryzen 3 7335U manages 4,495, a 451.4% gap. Single-core R20 shows 3,499 against 634, a 451.9% delta. Cinebench R15 produces the largest delta of the set: 5,948 versus 1,078 in multi-core is 451.8% ahead, and 839 versus 152 in single-core is 452.0% ahead. The EPYC 7573X's wins total 6, the Ryzen 3 7335U records 0 wins.

Interpreting these numbers requires context. The EPYC 7573X is a server/workstation part with a 71st percentile rank among all CPUs in the database. The Ryzen 3 7335U sits at the 70th percentile. Their average benchmark scores are close: 17,070 for the EPYC and 16,827 for the Ryzen. This apparent contradiction, near-identical average scores but a 451% blowout in Cinebench, resolves when one examines the benchmark mix. The Ryzen 3 7335U has additional PassMark results in the database, including data compression, encryption, and integer math workloads. Those tests are not present for the EPYC 7573X in the recorded data, so the averages are computed over different test sets.

The EPYC 7573X's nearest rivals in the database are the Intel Core i5-11400 at an average score of 17,067 (0% delta), Intel Core Ultra 7 164U at 17,074 (0% delta), AMD Ryzen 5 3600 at 17,035 (0.2% delta), and AMD EPYC 7H12 at 17,120 (-0.3% delta). The Ryzen 3 7335U's nearest rivals are the Intel Core i3-12100E at 16,853 (-0.2% delta), Intel Core i5-1235U at 16,770 (0.3% delta), Intel Core Ultra 5 115U at 16,753 (0.4% delta), and AMD Ryzen 5 7235HS at 16,902 (-0.4% delta). Neither part drifts far from its comparison group.

Architecture Differences

The EPYC 7573X belongs to the EPYC 7003 series, using the Zen 3 architecture under the Milan-X codename. The Ryzen 3 7335U is from the 7000 series, built on Zen 3+ under the Rembrandt-R codename. Both come from AMD, but they diverge sharply in nearly every physical and functional respect.

The EPYC 7573X is manufactured on a 7 nm process at TSMC, with 33,200 million transistors spread across 8 dies, each 81 mm². The Ryzen 3 7335U moves to a 6 nm process at the same foundry, with a single 208 mm² die. The EPYC's 8-die arrangement supports its enormous cache hierarchy. Each core gets 64 KB of L1 and 512 KB of L2, and the L3 is 768 MB shared across the package. The Ryzen 3 7335U also provides 64 KB of L1 and 512 KB of L2 per core, but its shared L3 is only 8 MB. The L3 difference of 768 MB versus 8 MB is the single largest architectural gulf between these parts.

Memory architecture differs correspondingly. The EPYC 7573X supports DDR4 over an eight-channel memory bus with 204.8 GB/s of bandwidth. The Ryzen 3 7335U supports DDR5 over a dual-channel bus with 76.8 GB/s. The EPYC offers PCIe Gen 4 with 128 lanes (CPU only); the Ryzen offers PCIe Gen 4 with 20 lanes (CPU only). The Ryzen 3 7335U integrates a Radeon 660M graphics unit, while the EPYC 7573X has no integrated graphics recorded.

The sockets are incompatible: AMD Socket SP3 for the EPYC, AMD Socket FP7 for the Ryzen. The EPYC is a server/workstation part; the Ryzen is a mobile part. Both are marked as Active in production status. The EPYC 7573X was released on 2022-03-21, and the Ryzen 3 7335U on 2023-01-03. Both have locked multipliers.

Specification Differences

The core and thread counts differ by an order of magnitude. The EPYC 7573X has 32 cores and 64 threads; the Ryzen 3 7335U has 4 cores and 8 threads. Base clocks are close, 2.80 GHz for the EPYC versus 3.00 GHz for the Ryzen, but boost clocks favor the Ryzen at 4.30 GHz versus 3.60 GHz. The TDP figures could not be more different: 280 W for the EPYC versus 28 W for the Ryzen.

Cache specifications are covered above but bear repeating in a spec context: 768 MB shared L3 for the EPYC, 8 MB shared L3 for the Ryzen. Memory support differs by generation and width: DDR4 eight-channel versus DDR5 dual-channel. Memory bandwidth is 204.8 GB/s versus 76.8 GB/s. PCIe lane counts are 128 versus 20, both Gen 4.

The EPYC 7573X has a launch MSRP of $5590. The Ryzen 3 7335U has no launch MSRP recorded. The EPYC's part number is 100-000000506WOF100-000000506; the Ryzen's part numbers are 100-000000537(FP7) and 100-000000549(FP7r2). The market segments are Server/Workstation for the EPYC and Mobile for the Ryzen.

Where Each One Wins

The EPYC 7573X wins in every recorded Cinebench head-to-head test, but the nature of those wins points to workload categories rather than a universal verdict. Multi-core performance is where the EPYC 7573X is most dominant: 451.4% ahead in Cinebench R23 multi-core, 451.4% ahead in R20 multi-core, and 451.8% ahead in R15 multi-core. These results align with its 32-core, 64-thread configuration and its 768 MB L3 cache. For server virtualization, database workloads, large-scale compilation, and any workload that scales across many threads, the EPYC 7573X is the clear choice. Its 71st percentile rank among all CPUs and its average benchmark score of 17,070 place it in the same performance class as the Intel Core i5-11400 and Intel Core Ultra 7 164U, despite its far larger core count, which suggests that in general-purpose average terms the massive core advantage is offset by the different benchmark compositions in the database.

Single-core performance also favors the EPYC 7573X, with 451.4% to 452.0% leads across Cinebench R15, R20, and R23. This is notable because the Ryzen 3 7335U has a higher boost clock (4.30 GHz versus 3.60 GHz) and a newer 6 nm process. The recorded data shows the EPYC's single-core scores are higher anyway, likely reflecting the server part's sustained clock behavior and large cache. For single-threaded legacy applications, the EPYC 7573X still wins in the recorded benchmarks.

The Ryzen 3 7335U does not win any head-to-head Cinebench test, but it has advantages that the EPYC 7573X cannot match. Its 28 W TDP against 280 W means it can operate in thin-and-light mobile systems where the EPYC's socket, power delivery, and cooling requirements are impossible. Its integrated Radeon 660M graphics provide display output and GPU acceleration without a discrete card. Its DDR5 memory support and dual-channel bus are appropriate for its mobile segment. Its PassMark results, such as 146,309 in data compression, 9,335 in data encryption, 42,493 in integer math, and 24,298 in floating-point math, show it is a capable mobile processor in its own right. Its average benchmark score of 16,827 and 70th percentile rank place it alongside the Intel Core i3-12100E and Intel Core i5-1235U.

The use-case split is therefore straightforward. The EPYC 7573X is for server and workstation deployments where raw multi-threaded throughput, massive L3 capacity, eight-channel memory bandwidth, and 128 PCIe lanes are the priorities. The Ryzen 3 7335U is for mobile laptops requiring modest multi-core performance, integrated graphics, low power consumption, and modern DDR5 support. The benchmark data shows a 451% performance gap in Cinebench, but the two products are not competing for the same socket, chassis, or thermal envelope.
