AMD EPYC 7573X vs AMD Ryzen 5 3600 Comparison

The AMD EPYC 7573X and AMD Ryzen 5 3600 occupy opposite ends of the AMD spectrum, yet their average benchmark scores place them within 0.2% of each other, at 17070 and 17035 respectively. This statistical tie in aggregate scoring, however, masks a fundamental divide in workload performance, driven by a 32-core server processor with 768 MB of L3 cache against a 6-core desktop chip with 32 MB. The data shows that the EPYC 7573X dominates every shared benchmark, while the Ryzen 5 3600's value lies in its efficiency, platform accessibility, and entirely different set of measured capabilities.

Where Each One Wins

The EPYC 7573X is the unequivocal winner in every head-to-head benchmark recorded, securing all 6 wins in the comparison set. Its victories are not marginal; they are sweeping, with deltas ranging from 292.1% to 292.3% across all Cinebench R15, R20, and R23 tests, both single-core and multi-core. This makes the EPYC 7573X the clear choice for multi-threaded server workloads, such as virtualization, database processing, and heavy compilation, where its 32 cores and 64 threads can be fully utilized. The sheer scale of the L3 cache, at 768 MB shared, further cements its position for data-intensive tasks that benefit from large on-die storage.

Conversely, the Ryzen 5 3600 wins in the categories not covered by the head-to-head data, specifically in the 3DMark and Passmark suites where it is the only processor with recorded scores. It delivers 4605 points in 3DMark's 16-thread test and 4603 in the max-thread test, showing strong scaling up to its 12 threads. Its Passmark single-thread score of 2562 is a notable data point, indicating solid per-core performance for its class. The Ryzen 5 3600's use case is desktop gaming and general productivity, where its 6 cores and 12 threads are sufficient, and its unlocked multiplier allows for user overclocking, a feature the EPYC lacks. The EPYC 7573X has no data for these specific tests, meaning the Ryzen 5 3600 is the only option for that benchmark subset.

Architecture Differences

The two processors are built on fundamentally different architectures, despite sharing the same 7 nm process node from TSMC. The EPYC 7573X is based on Zen 3, under the Milan-X codename, and is part of the EPYC 7003 series. It is a server-class chip designed for AMD Socket SP3, with a chiplet design comprising 8 dies, each 81 mm², totaling 33,200 million transistors. The Ryzen 5 3600 uses the older Zen 2 architecture, codenamed Matisse, part of the 3000 series. It is a desktop processor on AMD Socket AM4, with a single 74 mm² die containing 3,800 million transistors. This difference in transistor count and die size highlights the EPYC's scale, but the Ryzen's smaller footprint indicates a more power-efficient design per core.

Cache hierarchies are starkly different. The EPYC 7573X features 64 KB of L1 and 512 KB of L2 per core, matching the Ryzen 5 3600, but its L3 cache is 768 MB shared, a massive 24x increase over the Ryzen 5 3600's 32 MB shared L3. The EPYC's L3 is a key architectural feature for server workloads, reducing memory latency for frequently accessed data. The Ryzen 5 3600's smaller cache is typical for desktop parts, balancing cost and performance for consumer applications. Both lack integrated graphics, relying on discrete GPUs, but the EPYC 7573X supports ECC memory (true), while the Ryzen 5 3600 does not (false), a critical distinction for data integrity in server environments.

Memory and I/O capabilities further separate the two. The EPYC 7573X supports DDR4 memory over an eight-channel bus, providing 204.8 GB/s of bandwidth, and offers 128 PCIe Gen 4 lanes (CPU only). The Ryzen 5 3600 also supports DDR4 but over a dual-channel bus, yielding 51.2 GB/s, and provides only 16 PCIe Gen 4 lanes. This makes the EPYC 7573X a platform for massive memory throughput and expansion, while the Ryzen 5 3600 is constrained to typical desktop configurations.

Head-to-Head Benchmarks

In the direct comparisons, the EPYC 7573X's dominance is absolute and consistent. In Cinebench R15 multi-core, the EPYC scores 5948 against the Ryzen's 1516, a delta of 292.3%. The single-core R15 test shows a similar gap, with 839 versus 214, a 292.1% advantage. This pattern repeats across every Cinebench version. In R20 multi-core, the EPYC hits 24787 versus 6318, and in R20 single-core, 3499 versus 892, both at 292.3% deltas. The R23 results are equally lopsided: 59017 versus 15045 in multi-core and 8331 versus 2124 in single-core, with deltas of 292.3% and 292.2% respectively.

The consistency of the delta, hovering around 292% for both single and multi-core tests, is notable. It suggests that the EPYC 7573X's advantage is not merely from core count but also from superior per-core performance, likely due to the Zen 3 architecture's IPC improvements over Zen 2 and the massive L3 cache. The Ryzen 5 3600's scores are not weak for a 6-core part, but they are utterly dwarfed. For example, the Ryzen's R23 multi-core score of 15045 is respectable, yet the EPYC nearly quadruples it. There is no scenario in these benchmarks where the Ryzen 5 3600 wins; the EPYC 7573X is the sole victor in all 6 head-to-head tests, with the Ryzen 5 3600 recording 0 wins.

Specification Differences

The specification sheets reveal a processor designed for entirely different scales of operation. The EPYC 7573X has 32 cores and 64 threads, while the Ryzen 5 3600 has 6 cores and 12 threads. Base clocks differ significantly: the EPYC runs at 2.80 GHz, while the Ryzen starts at 3.60 GHz. Boost clocks are closer, with the EPYC at 3.60 GHz and the Ryzen at 4.20 GHz, but the EPYC's lower base clock is a trade-off for its higher core count and 280 W TDP. The Ryzen 5 3600's TDP is just 65 W, making it far more power-efficient for its performance class.

Socket and platform differences are absolute: the EPYC 7573X uses AMD Socket SP3, while the Ryzen 5 3600 uses AMD Socket AM4. The EPYC's memory bus is eight-channel with 204.8 GB/s bandwidth, versus the Ryzen's dual-channel 51.2 GB/s. PCIe lane counts are 128 versus 16, both Gen 4. The EPYC supports ECC memory (true), while the Ryzen does not (false). The EPYC 7573X has a launch MSRP of $5590, while the Ryzen 5 3600 has a launch MSRP of $199, reflecting their market segments. The Ryzen 5 3600 has an unlocked multiplier, allowing overclocking, while the EPYC 7573X does not. The EPYC's part number is 100-000000506 WOF100-000000506, and the Ryzen's is 100-000000031.
