AMD EPYC 74F3 vs AMD Ryzen 3 4100 Comparison

The AMD EPYC 74F3 and AMD Ryzen 3 4100 are both AMD processors, but they target entirely different market segments. The EPYC 74F3 is a 24-core, 48-thread server/workstation part designed for heavy multi-threaded workloads, while the Ryzen 3 4100 is a 4-core, 8-thread desktop chip for mainstream computing. Benchmark data shows the EPYC 74F3 dominates in every measured category, with performance deltas exceeding 448% in all Cinebench tests. However, the Ryzen 3 4100 offers a much lower launch MSRP of $99 and an unlocked multiplier, making it a different kind of product entirely. The following analysis breaks down the architectural differences, benchmark results, and use-case scenarios based strictly on the provided data.

FAQ

Q: Which processor has more cores and threads?

A: The AMD EPYC 74F3 has 24 cores and 48 threads, while the AMD Ryzen 3 4100 has 4 cores and 8 threads. This is a 6x difference in core count and a 6x difference in thread count.

Q: What is the performance difference in multi-core workloads?

A: In Cinebench R23 multi-core, the EPYC 74F3 scores 51,566 compared to the Ryzen 3 4100's 9,394, representing a 448.9% advantage for the EPYC. The delta is consistent across R15 (449.4%) and R20 (449%) multi-core tests as well.

Q: Does the Ryzen 3 4100 win in any benchmark?

A: No. According to head-to-head data, the EPYC 74F3 wins all 6 benchmark comparisons (Cinebench R15, R20, and R23 in both single-core and multi-core). The Ryzen 3 4100 has 0 wins.

Q: What are the memory channel configurations?

A: The EPYC 74F3 supports eight-channel DDR4 memory with a bandwidth of 204.8 GB/s, while the Ryzen 3 4100 supports dual-channel DDR4 with 51.2 GB/s bandwidth. The EPYC's memory bandwidth is exactly 4x higher.

Q: Are both processors on the same manufacturing process?

A: Yes, both use a 7 nm process node from TSMC. However, the EPYC 74F3 uses a 4x 81 mm² die configuration (Zen 3 Milan), while the Ryzen 3 4100 uses a single 156 mm² die (Zen 2 Renoir).

Q: What is the launch MSRP difference?

A: The EPYC 74F3 has a launch MSRP of $2900, while the Ryzen 3 4100 has a launch MSRP of $99. This is stated once here for reference; the analysis does not discuss value or affordability further.

Architecture Differences

The two processors represent different generations and design philosophies from AMD. The EPYC 74F3 is built on the Zen 3 architecture (codenamed Milan) and belongs to the EPYC generation, while the Ryzen 3 4100 uses the older Zen 2 architecture (codenamed Renoir) from the Ryzen 3 4000 series. This generational gap is significant: Zen 3 offers a substantial IPC improvement over Zen 2, which is reflected in the single-core benchmark results.

The physical design differs dramatically. The EPYC 74F3 uses a multi-chip module with 4x 81 mm² dies, totaling 33,200 million transistors. The Ryzen 3 4100 uses a monolithic 156 mm² die with 9,800 million transistors. The EPYC's chiplet design allows for a massive 256 MB shared L3 cache, whereas the Ryzen 3 4100 has only 8 MB shared L3 cache. Both have 64 KB L1 and 512 KB L2 per core.

Socket and platform support are entirely different. The EPYC 74F3 fits AMD Socket SP3 (server platform) and supports PCIe Gen 4 with 128 lanes (CPU only). The Ryzen 3 4100 uses AMD Socket AM4 (desktop platform) and supports PCIe Gen 3 with 8 lanes (CPU only). The EPYC also supports ECC memory, while the Ryzen 3 4100 does not. The EPYC's memory bus is eight-channel versus the Ryzen's dual-channel, giving the EPYC 4x the memory bandwidth (204.8 GB/s vs 51.2 GB/s).

Power characteristics differ as well: the EPYC 74F3 has a TDP of 240 watts, while the Ryzen 3 4100 has a TDP of 65 watts. The EPYC is not multiplier-unlocked, while the Ryzen 3 4100 has an unlocked multiplier. Both lack integrated graphics. The EPYC was released on 2021-03-14, while the Ryzen 3 4100 was released on 2022-04-03.

Head-to-Head Benchmarks

The benchmark data is remarkably one-sided. In every single Cinebench test, the EPYC 74F3 wins by roughly 449-451%. This consistency suggests the performance gap is driven by fundamental architectural and resource differences rather than workload-specific optimizations.

Looking at multi-core performance: in Cinebench R15, the EPYC scores 5,197 versus the Ryzen's 946, a 449.4% delta. In Cinebench R20, the EPYC scores 21,657 versus 3,945, a 449% delta. In Cinebench R23, the EPYC scores 51,566 versus 9,394, a 448.9% delta. The EPYC's advantage is essentially identical across all three versions of Cinebench, indicating that the 24-core/48-thread configuration scales almost perfectly relative to the 4-core/8-thread Ryzen.

Single-core results tell a similar story, albeit with slightly higher deltas. In Cinebench R15 single-core, the EPYC scores 733 versus the Ryzen's 133, a 451.1% delta. In R20 single-core, the EPYC scores 3,057 versus 556, a 449.8% delta. In R23 single-core, the EPYC scores 7,279 versus 1,326, a 448.9% delta. The fact that single-core performance also shows roughly 450% advantage is notable — it suggests the Zen 3 architecture in the EPYC has a significantly higher IPC than the Zen 2 in the Ryzen, even at similar boost clocks (both have a 4.00 GHz boost clock).

The EPYC 74F3's win count is 6, and the Ryzen 3 4100's win count is 0. There are no benchmarks where the Ryzen comes close. The smallest delta is 448.9% (R23 multi-core and single-core), and the largest is 451.1% (R15 single-core). This data shows a complete and utter performance domination by the EPYC 74F3 in all measured scenarios.

The Verdict

The data is unambiguous: the AMD EPYC 74F3 outperforms the AMD Ryzen 3 4100 in every benchmark tested. The EPYC's 24-core/48-thread configuration, combined with Zen 3 architecture and 256 MB L3 cache, delivers roughly 4.5x the performance of the Ryzen 3 4100's 4-core/8-thread Zen 2 design with 8 MB L3 cache. This holds true for both multi-core and single-core workloads.

However, the verdict depends entirely on the intended use case. The EPYC 74F3 is a server/workstation processor with eight-channel memory, 128 PCIe Gen 4 lanes, and ECC support. The Ryzen 3 4100 is a desktop processor with dual-channel memory, 8 PCIe Gen 3 lanes, and no ECC support. The EPYC is designed for heavy compute, virtualization, and data-center workloads. The Ryzen is designed for basic desktop tasks, light productivity, and entry-level gaming.

The Ryzen 3 4100 has one clear advantage beyond raw performance: it is multiplier-unlocked, allowing overclocking. The EPYC 74F3 is locked. Additionally, the Ryzen's lower TDP (65 vs 240 watts) makes it suitable for standard desktop cooling solutions, while the EPYC requires server-grade cooling. The Ryzen also has a later release date (2022-04-03 vs 2021-03-14).

For users who need maximum compute density, the EPYC 74F3 is the only choice. For users building a cost-sensitive desktop system, the Ryzen 3 4100 offers a functional platform with the ability to overclock. The benchmark data does not support any scenario where the Ryzen 3 4100 wins on performance.

Where Each One Wins

The EPYC 74F3 wins in every category measured by the benchmark data. Its six head-to-head wins cover Cinebench R15, R20, and R23 in both single-core and multi-core configurations. The performance deltas range from 448.9% to 451.1%, meaning the EPYC delivers roughly 5.5x the performance of the Ryzen 3 4100 in these tests.

Specifically, the EPYC 74F3 is the winner for:

• Multi-threaded rendering: Cinebench R23 multi-core score of 51,566 vs 9,394 (448.9% delta)
• Single-threaded tasks: Cinebench R23 single-core score of 7,279 vs 1,326 (448.9% delta)
• Legacy benchmark workloads: Cinebench R15 and R20, both single and multi-core, with deltas from 449% to 451.1%
• Memory-intensive workloads: Eight-channel memory with 204.8 GB/s bandwidth vs dual-channel 51.2 GB/s
• Server/Workstation scenarios: ECC memory support, 128 PCIe Gen 4 lanes, and Socket SP3 platform

The Ryzen 3 4100 has no benchmark wins. However, it has qualitative advantages that are not measured in the benchmark data:

• Overclocking: The unlocked multiplier allows users to push clocks beyond the 4.00 GHz boost clock, which the locked EPYC cannot do
• Power efficiency: 65 W TDP vs 240 W, meaning lower cooling requirements and potentially lower operating costs
• Desktop platform: Socket AM4 compatibility with mainstream motherboards, versus the server-only Socket SP3
• Newer release: Launched on 2022-04-03, over a year after the EPYC's 2021-03-14 release

The data clearly shows that the EPYC 74F3 is the performance winner in every measured benchmark. The Ryzen 3 4100's value lies in its different market positioning, not in benchmark performance. For any workload covered by Cinebench tests, the EPYC 74F3 is the superior processor by a factor of approximately 4.5x.
