AMD EPYC 74F3 vs AMD Ryzen 3 4300G Comparison

AMD EPYC 74F3 and AMD Ryzen 3 4300G occupy opposite ends of the performance spectrum, and the benchmark data reflects a complete dominance by the server-class chip. The EPYC 74F3 records a 515% advantage over the Ryzen 3 4300G in every Cinebench test, with its 24-core, 48-thread configuration utterly overwhelming the 4-core, 8-thread desktop part. While both CPUs share the same 4.00 GHz boost clock and 7 nm TSMC process node, the EPYC 74F3 delivers roughly six times the multi-threaded performance, making the comparison less about competition and more about illustrating the vast gulf between enterprise and entry-level desktop silicon.

Where Each One Wins

The AMD EPYC 74F3 wins every single benchmark in this comparison, taking all 6 head-to-head tests with zero victories for the Ryzen 3 4300G. The EPYC 74F3's Cinebench R23 multi-core score of 51,566 versus 8,387 for the Ryzen 3 4300G represents a 514.8% gap, highlighting its dominance in heavily threaded workloads. In single-core Cinebench R23, the EPYC 74F3 scores 7,279 against the Ryzen 3 4300G's 1,184, a 514.8% margin that shows the server chip's Zen 3 architecture outperforms the older Zen 2 design even on a per-thread basis.

The Ryzen 3 4300G's only advantages lie in its integrated Radeon Vega 6 graphics, unlocked multiplier, and significantly lower 65W TDP versus the EPYC 74F3's 240W. The desktop chip also uses the mainstream AMD Socket AM4, while the EPYC 74F3 requires the server-focused AMD Socket SP3 platform. For users needing a compact, power-efficient desktop system with built-in graphics, the Ryzen 3 4300G serves that role, but the EPYC 74F3 wins every measurable performance contest in the data.

The EPYC 74F3's 69th percentile ranking among all CPUs matches the Ryzen 3 4300G's identical 69th percentile, though this metric appears misleading given the massive benchmark disparities. The average benchmark score tells a clearer story: the EPYC 74F3 averages 14,915 across tests, while the Ryzen 3 4300G averages 14,503, a modest 2.8% difference that reflects the Ryzen 3 4300G's additional PassMark tests pulling its average upward.

Architecture Differences

The EPYC 74F3 employs Zen 3 architecture under the Milan codename, while the Ryzen 3 4300G uses Zen 2 with the Renoir codename. Both chips are manufactured on TSMC's 7 nm process node, but the EPYC 74F3 packs 33,200 million transistors across a 4x 81 mm² die configuration, compared to the Ryzen 3 4300G's 9,800 million transistors on a single 156 mm² die. This transistor budget translates directly into the EPYC 74F3's 24 cores and 48 threads versus the Ryzen 3 4300G's 4 cores and 8 threads.

Cache hierarchies diverge dramatically: the EPYC 74F3 features 256 MB of shared L3 cache, a 64x increase over the Ryzen 3 4300G's 4 MB of shared L3. Both chips maintain 64 KB of L1 cache per core and 512 KB of L2 cache per core, but the sheer L3 capacity difference explains why the EPYC 74F3 excels in data-intensive server workloads. Memory support also separates the two: the EPYC 74F3 runs eight-channel DDR4 with 204.8 GB/s bandwidth and ECC support, while the Ryzen 3 4300G uses dual-channel DDR4 with 51.2 GB/s bandwidth and no ECC capability.

PCIe connectivity differs by generation and lane count, with the EPYC 74F3 offering Gen 4 with 128 CPU-only lanes versus the Ryzen 3 4300G's Gen 3 with 16 CPU-only lanes. The EPYC 74F3 targets the Server/Workstation market segment, while the Ryzen 3 4300G serves Desktop users. The Ryzen 3 4300G includes integrated Radeon Vega 6 graphics, a feature entirely absent from the EPYC 74F3, and offers an unlocked multiplier for overclocking, whereas the EPYC 74F3's multiplier remains locked.

The Verdict

The data supports only one conclusion: the AMD EPYC 74F3 is the overwhelmingly superior processor for any compute-intensive task. Its Cinebench R23 multi-core score of 51,566 exceeds the Ryzen 3 4300G's 8,387 by 514.8%, and its single-core advantage of 514.8% (7,279 versus 1,184) proves the Zen 3 architecture's per-thread superiority over Zen 2. The EPYC 74F3's 256 MB L3 cache, eight-channel memory with 204.8 GB/s bandwidth, and 128 PCIe Gen 4 lanes make it purpose-built for server workloads where massive data throughput and parallel processing are essential.

The Ryzen 3 4300G finds its place in desktop systems requiring integrated graphics, lower power consumption (65W versus 240W), and mainstream socket compatibility. Its unlocked multiplier and AM4 socket appeal to budget-conscious builders, though the benchmark data shows no performance scenario where it outperforms the EPYC 74F3. The Ryzen 3 4300G's additional PassMark tests (data compression, encryption, floating-point math, and others) provide a broader profile, but all show modest scores consistent with its 4-core configuration.

For server and workstation deployments, the EPYC 74F3's 24 cores, 48 threads, and 515% multi-core advantage make it the clear choice, with a launch MSRP of $2900 reflecting its enterprise positioning. For lightweight desktop applications, light gaming, or HTPC builds where integrated graphics matter, the Ryzen 3 4300G's 65W TDP and Radeon Vega 6 offer a viable low-power solution, but users should expect roughly one-sixth the multi-threaded performance of the EPYC 74F3.
