AMD EPYC 9654P vs AMD Ryzen 5 8600G Comparison

The AMD EPYC 9654P and AMD Ryzen 5 8600G represent two radically different interpretations of what a CPU should be. The EPYC 9654P is a 96-core server behemoth built for throughput, while the Ryzen 5 8600G is a 6-core desktop processor with integrated graphics. Benchmark results reveal a predictable yet dramatic divide, with the server chip dominating multi-threaded workloads and the desktop part claiming a surprising victory in single-threaded performance.

Head-to-Head Benchmarks

The most striking pattern in the head-to-head data is the sheer magnitude of the EPYC 9654P's multi-core advantage. In Cinebench R23 multi-core, the EPYC 9654P scores 98,875 against the Ryzen 5 8600G's 21,503, a delta of 359.8%. This is not a marginal lead; it is a four-and-a-half-fold increase in raw rendering throughput. The same story repeats across every Cinebench iteration: R15 multi-core shows a 359.9% delta (9,966 vs 2,167), R20 multi-core shows 359.8% (41,527 vs 9,031), and R23 single-core also shows a massive 359.9% delta (13,958 vs 3,035). The EPYC's single-core advantage in Cinebench is equally lopsided, with R15 single-core at 361% (1,406 vs 305) and R20 single-core at 360.1% (5,862 vs 1,274). These results indicate that the EPYC 9654P's architecture delivers far superior per-thread performance in this specific benchmark suite.

Geekbench tells a more nuanced story. In multi-core, the EPYC 9654P wins with 22,141 against 10,850, a 104.1% delta — still a double, but far less dramatic than the Cinebench results. However, the Ryzen 5 8600G takes the single-core crown in Geekbench, scoring 2,433 against the EPYC's 1,981, a delta of -18.6% in favor of the desktop chip. This is the only benchmark win for the Ryzen 5 8600G across the entire head-to-head set, and it highlights a key architectural difference: the 8600G's higher boost clock of 5.00 GHz versus the EPYC's 3.70 GHz allows it to excel in lightly-threaded, latency-sensitive tasks that Geekbench measures. The EPYC still wins the overall benchmark count 7 to 1, but the single Geekbench victory for the 8600G is significant because it suggests that for everyday desktop responsiveness, the smaller chip is not merely adequate — it is superior.

Architecture Differences

The two CPUs share the Zen 4 architecture and TSMC as their foundry, but diverge sharply in nearly every other physical attribute. The EPYC 9654P, codenamed Genoa, is built on a 5 nm process and packs 78,840 million transistors across a massive 12-chiplet design with a die size of 12x 72 mm². The Ryzen 5 8600G, codenamed Phoenix, uses a more advanced 4 nm process with 25,000 million transistors on a monolithic 178 mm² die. This process advantage explains part of the 8600G's single-core win: the smaller node allows for higher clock speeds at lower power, with the 8600G boosting to 5.00 GHz versus the EPYC's 3.70 GHz.

Cache configuration further separates the two. Both allocate 64 KB of L1 and 1 MB of L2 per core, but the EPYC's shared L3 cache is a colossal 384 MB, compared to the 8600G's 16 MB. That 24-fold difference in L3 capacity is directly tied to the EPYC's 96-core design, which requires a vast pool of shared data to keep all cores fed. Memory support also differs fundamentally: the EPYC uses twelve-channel DDR5 with a theoretical bandwidth of 460.8 GB/s, while the 8600G uses dual-channel DDR5 at 83.2 GB/s. The EPYC also supports ECC memory, while the 8600G does not. PCIe connectivity is another major split, with the EPYC offering Gen 5 with 128 lanes versus the 8600G's Gen 4 with 20 lanes.

The most visible feature difference is the integrated graphics. The EPYC 9654P has none, while the Ryzen 5 8600G includes a Radeon 760M iGPU, making it a complete desktop package out of the box. The 8600G also has an unlocked multiplier, whereas the EPYC's is locked. The socket and market segments reinforce the intent: the EPYC uses AMD Socket SP5 and is designed for Server/Workstation use, while the 8600G sits in AMD Socket AM5 and targets Desktop. Production status for both is Active.

The Verdict

The data paints a clear picture: the AMD EPYC 9654P is the undisputed champion for multi-threaded, server-class workloads. Its 96 cores and 192 threads deliver Cinebench R23 multi-core scores of 98,875, which is 359.8% ahead of the Ryzen 5 8600G. For any task that scales with core count — rendering, scientific computing, virtualization, or database processing — the EPYC 9654P is the only rational choice from this comparison. Its 384 MB of L3 cache and 460.8 GB/s memory bandwidth are designed to feed those cores, and the 128 PCIe Gen 5 lanes allow for massive I/O expansion.

The Ryzen 5 8600G wins the single-threaded Geekbench battle with a score of 2,433, beating the EPYC's 1,981 by 18.6%. This is a direct result of its higher 5.00 GHz boost clock and more modern 4 nm process. For a desktop user who cares about snappy application launches, responsive web browsing, or gaming performance that relies on single-core speed, the 8600G is the better fit. Its integrated Radeon 760M also means it can run entirely without a discrete GPU, which the EPYC cannot do. The 8600G's 65 W TDP versus the EPYC's 360 W TDP further underscores its suitability for standard desktop power envelopes.

The verdict is not a question of which is "better" — it is a question of which workload you are feeding. The EPYC 9654P is a server part that happens to be compared here; the Ryzen 5 8600G is a desktop part that excels in consumer scenarios. The data does not support a single winner. It supports a clear division of labor.
