AMD EPYC 7573X vs AMD Ryzen 3 PRO 8300G Comparison

The AMD Ryzen 3 PRO 8300G and AMD EPYC 7573X are both AMD processors, but they target opposite ends of the computing spectrum. The Ryzen 3 PRO 8300G is a 4-core desktop chip on the modern AM5 platform, while the EPYC 7573X is a 32-core server behemoth on the SP3 platform. Benchmark results show a complete sweep for the EPYC part in every head-to-head test, but the data also reveals a story about single-thread efficiency and platform capabilities that makes the comparison more nuanced than a simple scoreboard.

Head-to-Head Benchmarks

The Cinebench results are unambiguous: the EPYC 7573X wins all six head-to-head tests, with a consistent performance delta of -79.1% for the Ryzen 3 PRO 8300G across every single test. In Cinebench R23 multi-core, the EPYC scores 59017 against the Ryzen’s 12359. That is a massive gap, roughly 4.8x the score, driven by the EPYC’s 32 cores and 64 threads versus the Ryzen’s 4 cores and 8 threads.

However, the single-core results are more revealing about architectural efficiency. In Cinebench R23 single-core, the EPYC scores 8331, while the Ryzen 3 PRO 8300G scores 1744. The EPYC still wins by the same -79.1% delta, but the Ryzen’s higher boost clock of 4.90 GHz against the EPYC’s 3.60 GHz does not translate into a win. The EPYC’s Zen 3 architecture with 768 MB of L3 cache clearly provides a raw throughput advantage per thread in this workload, despite the Ryzen’s newer Zen 4 design and higher clock speed.

The pattern holds across older Cinebench versions. In Cinebench R20 multi-core, the EPYC posts 24787 versus the Ryzen’s 5190. In R15 multi-core, the EPYC hits 5948 against the Ryzen’s 1245. The single-core scores follow the same trend: R20 shows 3499 for the EPYC and 732 for the Ryzen, while R15 shows 839 versus 175. Every result carries the exact same -79.1% delta, indicating a perfectly linear scaling difference between the two parts in this benchmark suite.

Looking at the average benchmark scores, the two processors are remarkably close overall. The Ryzen 3 PRO 8300G has an average benchmark score of 17278, while the EPYC 7573X sits at 17070. This places the Ryzen 0.2% ahead of the EPYC in aggregate, which is a statistical tie. The Ryzen’s nearest rivals include the Intel Core i5-12450H (delta 0.2%) and AMD Ryzen 3 210 (delta -0.2%), while the EPYC’s rivals include the Intel Core i5-11400 (delta 0%) and AMD EPYC 7H12 (delta -0.3%). Both chips sit at the 71st percentile of all CPUs, meaning their overall performance profiles are comparable in the broader database, even though the Cinebench scores are wildly different.

Where Each One Wins

The EPYC 7573X wins every multi-threaded workload in the head-to-head data. Its 32 cores and 64 threads dominate Cinebench R15, R20, and R23 multi-core tests by a factor of roughly 4.8x. This makes it the clear choice for any workload that scales with core count, such as server virtualization, database processing, or heavy compilation tasks. The EPYC’s 768 MB of L3 cache is a massive advantage for data-heavy server workloads, as it can hold far more working set in cache than the Ryzen’s 8 MB.

The Ryzen 3 PRO 8300G wins in the platform mobility and efficiency categories, though not in raw benchmark scores. It has a TDP of 65 watts versus the EPYC’s 280 watts, making it far more suitable for a desktop or small form factor build. The Ryzen also has integrated graphics (Radeon 740M), which the EPYC lacks entirely. For a user who needs a basic display output without a discrete GPU, the Ryzen is the only option here. The Ryzen also supports DDR5 memory, while the EPYC is limited to DDR4, which gives the newer platform a potential longevity advantage even if the EPYC’s eight-channel memory bus offers far more bandwidth.

The single-core Cinebench results are interesting because the EPYC wins them, but the margin is the same -79.1% as multi-core. This suggests the EPYC’s per-core performance is substantially higher than the Ryzen’s, which is counterintuitive given the Ryzen’s higher boost clock. The EPYC’s Zen 3 architecture with 3D V-Cache (implied by the 768 MB L3) likely provides a per-thread performance advantage that clock speed alone cannot overcome. For workloads that are lightly threaded but cache-sensitive, the EPYC would still win.

Architecture Differences

The Ryzen 3 PRO 8300G is built on Zen 4 architecture with a 4 nm process node from TSMC, while the EPYC 7573X uses Zen 3 on a 7 nm node. The Ryzen’s process advantage allows it to pack 20,900 million transistors into a 137 mm² die, whereas the EPYC spreads 33,200 million transistors across 8x 81 mm² dies. The Ryzen uses a monolithic design with 4 cores, while the EPYC is a chiplet design with 32 cores.

Cache configurations differ dramatically. The Ryzen has 64 KB of L1 per core, 1 MB of L2 per core, and 8 MB of shared L3. The EPYC also has 64 KB of L1 per core but only 512 KB of L2 per core, yet it has a massive 768 MB of shared L3. This 96x difference in L3 cache is the defining architectural feature of the EPYC, designed for server workloads that repeatedly access large datasets.

Memory support diverges as well. The Ryzen uses dual-channel DDR5 with 83.2 GB/s bandwidth, while the EPYC uses eight-channel DDR4 with 204.8 GB/s bandwidth. Both support ECC memory. PCIe connectivity also differs: the Ryzen offers 14 Gen 4 lanes, while the EPYC offers 128 Gen 4 lanes. The EPYC’s socket is SP3, designed for dual-socket servers, while the Ryzen uses AM5 for single-socket desktops. The Ryzen was released on 2024-04-15, while the EPYC came out on 2022-03-21.

The Verdict

If the workload is multi-threaded server processing, the EPYC 7573X is the only choice. Its Cinebench multi-core scores are roughly 4.8x higher than the Ryzen 3 PRO 8300G, and its 768 MB of L3 cache is purpose-built for data-heavy server tasks. The EPYC also has 128 PCIe Gen 4 lanes and eight-channel DDR4 memory, making it suited for enterprise environments with high I/O demands.

If the workload is desktop productivity with a need for integrated graphics, the Ryzen 3 PRO 8300G is the practical pick. It has a 65-watt TDP, supports DDR5, and includes Radeon 740M graphics, so it can run a display without a separate GPU. The Ryzen also has a higher boost clock and a smaller die, making it a better fit for compact systems.

The data shows a tie in average benchmark scores (17278 vs 17070), but that aggregate hides the extreme differences in core count and cache. The Ryzen is a modern, efficient desktop chip; the EPYC is a cache-heavy server monster. Buyers should choose based on platform needs, not raw Cinebench numbers, because the single-core results still favor the EPYC despite the Ryzen’s clock advantage.
