AMD EPYC 7773X vs AMD Ryzen 3 PRO 8300GE Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep for the AMD EPYC 7773X across all six shared benchmark tests. The EPYC 7773X wins every Cinebench iteration, both multicore and singlecore, with margins that remain remarkably consistent. In Cinebench R15 multicore, the EPYC 7773X scores 7825 against the Ryzen 3 PRO 8300GE's 1260, a delta of 521%. The singlecore R15 result is nearly identical in percentage terms: 1104 versus 177, a 523.7% advantage.

Moving to Cinebench R20, the pattern holds. The EPYC 7773X posts 32608 multicore versus 5254 for the Ryzen 3 PRO 8300GE, a 520.6% difference. In R20 singlecore, the scores are 4603 and 741 respectively, a 521.2% gap. Cinebench R23 multicore shows 77639 against 12511, again 520.6% ahead, while R23 singlecore delivers 10960 versus 1766, matching the same 520.6% delta.

The consistency of these deltas is notable. Across all six tests, the percentage advantage ranges only from 520.6% to 523.7%. This suggests the performance gap is structural rather than workload-dependent; the EPYC 7773X simply has a massive resource advantage that scales uniformly. The Ryzen 3 PRO 8300GE, despite its higher boost clock, cannot close the gap in any single-threaded test either, which is unusual when comparing a 64-core server chip against a 4-core desktop part.

In the overall database rankings, both processors sit in similar percentiles: the EPYC 7773X at 73rd percentile versus the Ryzen 3 PRO 8300GE at 72nd. The average benchmark scores are 18979 for the EPYC and 18505 for the Ryzen, a difference of only 2.5%. This close average hides the extreme variance: the EPYC dominates Cinebench tests while the Ryzen has additional PassMark tests recorded that the EPYC does not have, which pulls their averages closer. The nearest rivals for the EPYC include the Intel Core i5-1335U at 18982 (0% delta) and the Intel Core i5-12400F at 19039 (-0.3%). For the Ryzen 3 PRO 8300GE, the nearest rival is the Intel Core i5-13420H at 18511 (0% delta), followed by the Intel Core i3-14100F at 18519 (-0.1%).

Architecture Differences

The two processors come from different AMD generations entirely. The EPYC 7773X is part of the EPYC 7003 series, built on Zen 3 architecture with the Milan-X codename, released in March 2022. The Ryzen 3 PRO 8300GE belongs to the 8000 series, using Zen 4 architecture with the Phoenix2 codename, released in April 2024. The process nodes differ: the EPYC uses 7 nm TSMC fabrication, while the Ryzen uses 4 nm TSMC.

Core counts are the most dramatic divergence. The EPYC 7773X has 64 cores and 128 threads, whereas the Ryzen 3 PRO 8300GE has 4 cores and 8 threads. This 16x core difference explains the multicore benchmark results. The EPYC's L3 cache is 768 MB shared, a figure enabled by its Milan-X design with 3D stacked cache. The Ryzen has 8 MB shared L3. L1 cache is identical at 64 KB per core, but L2 differs: 512 KB per core on the EPYC versus 1 MB per core on the Ryzen.

Memory support also diverges sharply. The EPYC runs DDR4 with an eight-channel memory bus and 204.8 GB/s bandwidth. The Ryzen runs DDR5 with a dual-channel bus and 83.2 GB/s bandwidth. Both support ECC memory, a point in favor of the Ryzen given its desktop positioning. PCIe lanes differ as well: the EPYC provides 128 Gen 4 lanes CPU-only, while the Ryzen provides 14 Gen 4 lanes CPU-only. The Ryzen integrates Radeon 740M graphics; the EPYC has no integrated graphics.

Transistor counts and die sizes reflect their different scales. The EPYC uses 33,200 million transistors across 8x 81 mm² dies. The Ryzen uses 20,900 million transistors on a single 137 mm² die. The EPYC's TDP is 280 watts, while the Ryzen's is 35 watts, an 8x difference that underscores their intended deployment environments. The EPYC targets server/workstation use on AMD Socket SP3; the Ryzen targets desktop on AMD Socket AM5.

The Verdict

The data points to two entirely different usage profiles. The EPYC 7773X is the clear choice for any workload that exploits its 64 cores and 128 threads. In Cinebench R23 multicore, it scores 77639, more than six times the Ryzen's 12511. The Ryzen 3 PRO 8300GE cannot compete in any recorded benchmark; it loses every head-to-head test by a minimum of 520.6%.

However, the Ryzen's strengths lie outside the shared benchmark set. It has a higher boost clock at 4.90 GHz, a newer 4 nm process, DDR5 memory support, integrated Radeon 740M graphics, and a 35 watt TDP. These features make it suitable for compact desktop systems where power draw and integrated graphics matter. The EPYC's 280 watt TDP and lack of integrated graphics require a server platform with discrete GPU support.

The percentile rankings tell a nuanced story. Both sit near the 72nd to 73rd percentile of all CPUs in the database, meaning neither is an outlier in overall performance. The EPYC's average score of 18979 is dragged down by its relatively weaker single-core results in context, while the Ryzen's average of 18505 benefits from additional PassMark tests that measure integer math, floating point math, and data compression, areas where its higher clock speed helps.

For a server context with heavy parallel workloads, the EPYC 7773X is the only rational pick based on these numbers. For a desktop context with modest core requirements, the Ryzen 3 PRO 8300GE offers a lower-power path with modern features. The data does not support any scenario where the Ryzen outperforms the EPYC in Cinebench, but it also does not support using a 280 watt server chip in a desktop.

Where Each One Wins

The EPYC 7773X wins every head-to-head benchmark recorded in the database. In Cinebench R15, R20, and R23, both multicore and singlecore, it holds a consistent 520% to 524% advantage. These wins stem from its 64 cores, 128 threads, and 768 MB L3 cache. The EPYC is the decisive choice for multi-threaded server workloads, data center virtualization, and compute-heavy batch processing. Its eight-channel memory bandwidth of 204.8 GB/s supports memory-intensive applications, and its 128 PCIe Gen 4 lanes enable extensive expansion.

The Ryzen 3 PRO 8300GE wins in areas not covered by the shared benchmarks. Its 35 watt TDP makes it suitable for low-power desktop builds where thermal output and electricity consumption are primary concerns. Its integrated Radeon 740M graphics eliminates the need for a discrete GPU in basic systems. The newer 4 nm process and DDR5 memory support give it a modern platform foundation. Its higher boost clock of 4.90 GHz benefits lightly threaded tasks, though the recorded singlecore Cinebench scores do not reflect this advantage against the EPYC. The Ryzen also has exclusive PassMark results showing a single-thread score of 3828, data compression at 162623, and integer math at 40348, but these have no EPYC counterpart in the database for direct comparison.

Use-case selection is straightforward from the data. Choose the EPYC 7773X for server racks, database workloads, and any scenario where core count and cache size dominate. Choose the Ryzen 3 PRO 8300GE for desktop productivity, small form factor systems, and applications that benefit from integrated graphics and lower power draw. The two processors do not compete for the same buyer; their specifications place them in separate market segments with distinct priorities.
