AMD EPYC 7702P vs AMD Ryzen 3 4300G Comparison

The AMD EPYC 7702P and AMD Ryzen 3 4300G occupy opposite ends of the AMD spectrum, sharing a Zen 2 foundation but diverging completely in purpose. The data shows a total dominance for the EPYC part across every recorded benchmark, with the Ryzen APU offering no single victory in the head-to-head tests. This comparison is not about close competition; it is about illustrating the scale of difference between a 64-core server processor and a 4-core desktop chip with integrated graphics.

Head-to-Head Benchmarks

The benchmark results are unequivocal. The AMD EPYC 7702P wins all six recorded comparisons, with the margin of victory consistently exceeding 523%. In Cinebench R15 multi-core, the EPYC scores 5272 against the Ryzen 3's 845, a delta of 523.9%. The single-core test tells a similar story, with the EPYC at 744 and the Ryzen at 119, a 525.2% advantage. This is not a case of the server chip merely having more cores; its single-thread performance is also dramatically higher in these tests.

Moving to Cinebench R20, the pattern holds. The EPYC 7702P posts a multi-core score of 21969, while the Ryzen 3 4300G manages 3522. That is a 523.8% lead for the EPYC. The single-core R20 numbers are 3101 versus 497, a 523.9% delta. The data indicates that the EPYC's architecture delivers superior instructions per clock in these workloads, not just a raw core count advantage.

The most modern test in the set, Cinebench R23, reinforces the trend. The EPYC 7702P achieves 52308 in multi-core, compared to the Ryzen 3's 8387, a 523.7% difference. In R23 single-core, the scores are 7384 and 1184 respectively, a 523.6% lead for the EPYC. The consistency of these deltas, hovering around 523-525%, suggests a fundamental throughput advantage that scales across all rendering tests.

The Ryzen 3 4300G has zero wins in the head-to-head comparison. While it has additional PassMark benchmarks recorded for data compression and encryption, these are not part of the direct head-to-head set, so they cannot be used to claim a victory. The recorded data shows a clean sweep for the EPYC 7702P, with all six head-to-head metrics favoring the server processor. The average benchmark score also reflects this gap, with the EPYC at 15130 and the Ryzen 3 at 14503, though this aggregate figure is less dramatic due to the different benchmark sets included.

Architecture Differences

Both processors are built on the Zen 2 architecture and use a 7 nm process from TSMC, but their implementations are radically different. The EPYC 7702P, codenamed Rome, is a server-class chip with 64 cores and 128 threads. The Ryzen 3 4300G, codenamed Renoir, is a desktop APU with 4 cores and 8 threads. The transistor counts reflect this chasm: the EPYC packs 3,800 million transistors on a 74 mm² die, while the Ryzen 3 integrates 9,800 million transistors on a 156 mm² die. The larger transistor count on the smaller chip is due to the integrated Radeon Vega 6 graphics, which the EPYC lacks entirely.

The cache hierarchy is another major differentiator. The EPYC 7702P features 96 KB of L1 cache per core and 512 KB of L2 per core, matching the Ryzen 3's L2 allocation. However, the L3 cache is a stark contrast: the EPYC has 256 MB shared, while the Ryzen 3 has only 4 MB shared. This 64x difference in L3 capacity is critical for server workloads that need to keep massive datasets close to the cores. The Ryzen 3's smaller cache is typical for a desktop part, where power and cost are more constrained.

Memory support also diverges sharply. The EPYC 7702P uses eight-channel DDR4 with a bandwidth of 204.8 GB/s, while the Ryzen 3 4300G uses dual-channel DDR4 with 51.2 GB/s. This fourfold bandwidth advantage for the EPYC is essential for feeding 64 cores. The EPYC also supports ECC memory, while the Ryzen 3 does not, a feature expected in server environments. The PCIe implementation differs as well: the EPYC is Gen 4, while the Ryzen 3 is Gen 3 with 16 lanes from the CPU only.

The sockets are incompatible, with the EPYC on AMD Socket SP3 and the Ryzen 3 on AMD Socket AM4. The EPYC has a base clock of 2000 MHz and a boost of 3.35 GHz, while the Ryzen 3 has a higher base clock of 3.80 GHz and a boost of 4.00 GHz. Despite the higher clocks, the Ryzen 3 cannot overcome the core and cache deficit. The EPYC also has a TDP of 200 watts, significantly higher than the Ryzen 3's 65 watts, reflecting the energy required to run 64 cores.

The Verdict

The data leads to a clear verdict: the AMD EPYC 7702P is the superior processor for any workload that can leverage its massive core count and memory bandwidth. In every Cinebench test, it outperforms the Ryzen 3 4300G by more than 523%, which is a decisive margin. The EPYC's 64 cores and 128 threads, combined with 256 MB of L3 cache and eight-channel memory, make it a purpose-built machine for multi-threaded server tasks. Its average benchmark score of 15130 versus the Ryzen 3's 14503 confirms its overall higher performance level.

The Ryzen 3 4300G, however, is not without merit in its own context. It is a desktop processor with a lower TDP of 65 watts, a higher boost clock of 4.00 GHz, and an unlocked multiplier. It also includes integrated Radeon Vega 6 graphics, eliminating the need for a discrete GPU in basic systems. For a user building a compact desktop PC where power consumption and integrated graphics are priorities, the Ryzen 3 is the sensible choice. Its 4 cores and 8 threads are sufficient for everyday computing, and its dual-channel memory is adequate for that class of system.

The verdict is not about which chip is "better" in an absolute sense, but which is appropriate for its intended market. The EPYC 7702P is for servers and workstations that demand maximum throughput. The Ryzen 3 4300G is for desktops that prioritize efficiency and integrated graphics. The benchmark data shows no reason to choose the Ryzen 3 for heavy multi-core workloads; the EPYC is the clear winner there. Conversely, the data does not support using an EPYC in a typical desktop scenario where its power draw and lack of integrated graphics would be impractical.

Specification Differences

The two processors differ on nearly every specification field. The most obvious is core count: 64 cores for the EPYC versus 4 for the Ryzen 3. Threads follow suit at 128 versus 8. Base clocks are 2000 MHz for the EPYC and 3800 MHz for the Ryzen 3, while boost clocks are 3.35 GHz and 4.00 GHz respectively. The TDP is 200 watts versus 65 watts. The EPYC uses Socket SP3, the Ryzen 3 uses Socket AM4. The L1 cache is 96 KB per core for the EPYC and 64 KB per core for the Ryzen 3. L2 cache is identical at 512 KB per core. L3 cache is 256 MB shared for the EPYC and 4 MB shared for the Ryzen 3. Memory bus is eight-channel versus dual-channel, with bandwidth of 204.8 GB/s versus 51.2 GB/s. ECC support is present on the EPYC and absent on the Ryzen 3. PCIe is Gen 4 for the EPYC and Gen 3 with 16 lanes for the Ryzen 3. The EPYC has no integrated graphics, while the Ryzen 3 has Radeon Vega 6. The EPYC's multiplier is locked, while the Ryzen 3's is unlocked. The EPYC is from the EPYC 7002 series, released on 2019-08-06, while the Ryzen 3 is from the 4000 series, released on 2020-07-20.

Where Each One Wins

The AMD EPYC 7702P wins in all multi-core and single-core rendering benchmarks recorded, with deltas consistently above 523%. Its strengths are in server-class workloads: virtual machines, database processing, scientific computing, and any task that can utilize 128 threads. The 256 MB L3 cache and 204.8 GB/s memory bandwidth give it a decisive edge in data-heavy applications. The EPYC also wins on PCIe Gen 4 support and ECC memory, both critical for enterprise reliability.

The AMD Ryzen 3 4300G wins in scenarios not measured by the head-to-head tests. It has a lower TDP of 65 watts, making it suitable for power-constrained desktop builds. Its integrated Radeon Vega 6 graphics means a system can run without a discrete GPU, which is a clear advantage for basic office PCs or home theater setups. The unlocked multiplier offers overclocking potential, something the locked EPYC cannot do. The higher boost clock of 4.00 GHz also benefits lightly threaded tasks, though the recorded single-core Cinebench results show the EPYC still wins those tests. For a user prioritizing low power consumption, integrated graphics, and desktop affordability, the Ryzen 3 4300G is the appropriate choice. For any workload that demands maximum compute throughput, the EPYC 7702P is the only option based on the data.
