Architecture Differences

The EPYC 9654 belongs to the EPYC 9004 series, built on Zen 4 architecture under the Genoa codename. It uses a 5 nm process at TSMC, with 78,840 million transistors spread across 12 dies of 72 mm² each. The EPYC 7203P belongs to the EPYC 7003 series, built on Zen 3 architecture under the Milan codename. It uses a 7 nm process at TSMC, with 8,300 million transistors across 2 dies of 81 mm² each.

Cache layouts differ substantially. Both processors share a 64 KB L1 per core. The L2 cache is 1 MB per core on the 9654 versus 512 KB per core on the 7203P. L3 cache is 384 MB shared on the 9654 versus 64 MB shared on the 7203P.

Memory architecture diverges completely. The 9654 uses DDR5 with a twelve-channel memory bus and 460.8 GB/s bandwidth. The 7203P uses DDR4 with an eight-channel bus and 204.8 GB/s bandwidth. Both support ECC memory.

PCIe generations differ. The 9654 supports PCIe Gen 5 with 128 lanes (CPU only). The 7203P supports PCIe Gen 4 with 128 lanes (CPU only).

Socket and platform differ. The 9654 uses AMD Socket SP5, while the 7203P uses AMD Socket SP3. The 9654 has a TDP of 360, and the 7203P has a TDP of 120. Neither processor has an unlocked multiplier, and neither has integrated graphics.

Clock behavior also separates the two. The 9654 has a base clock of 2.40 GHz and a boost clock of 3.70 GHz. The 7203P has a higher base clock of 2.80 GHz but a lower boost clock of 3.40 GHz.

Release timing places the 9654 first, launched on 2022-11-09, while the 7203P launched on 2023-09-04. Both remain active in production.

The Verdict

The data points to a clear segmentation. The EPYC 9654 is the processor for massive parallel throughput. It wins every recorded benchmark by a wide margin. The EPYC 7203P is the processor for modest workloads where its lower TDP and higher base clock matter.

The 9654 is the only choice when the workload scales beyond a handful of cores. Its 96 cores and 192 threads produce Cinebench multi-core scores that are over 443% higher than the 7203P in every multi-core test. The 7203P cannot match this in any scenario measured.

The 7203P makes sense for single-socket servers with light or latency-sensitive tasks. Its 8 cores and 16 threads, combined with a 2.80 GHz base clock, provide a simpler footprint. The 120 TDP is far lower than the 9654's 360, which affects cooling and power infrastructure requirements.

For users who need the highest single-thread performance, the 9654 still leads. Its Cinebench R23 single-core score of 14354 is 443.3% above the 7203P's 2642. The 7203P does not win in any benchmark category recorded.

The verdict is straightforward: the 9654 dominates on raw performance, and the 7203P serves as a lower-power entry point. Neither processor is a substitute for the other.

Head-to-Head Benchmarks

The head-to-head data set contains six Cinebench tests, and the EPYC 9654 wins all of them. The deltas are remarkably consistent, hovering around 443% in every test.

In Cinebench R15 multi-core, the 9654 scores 10248 versus the 7203P's 1886, a delta of 443.4%. In R15 single-core, the 9654 scores 1446 versus 266, a delta of 443.6%. The single-core gap is slightly larger than the multi-core gap.

Cinebench R20 shows the same pattern. Multi-core: 42703 versus 7859, a 443.4% delta. Single-core: 6028 versus 1109, a 443.6% delta. The 9654's advantage holds across both core-count scaling and per-thread performance.

Cinebench R23 records the largest absolute scores. Multi-core: 101675 versus 18714, a 443.3% delta. Single-core: 14354 versus 2642, also a 443.3% delta. The multi-core gap in absolute terms is enormous, roughly 83,000 points.

The consistency of the delta across tests is notable. Whether the workload is single-threaded or multi-threaded, the 9654 maintains a near-identical percentage advantage. This suggests the 9654's advantage comes from both higher per-core throughput and far greater core count.

The 7203P has no wins in the head-to-head set. Its benchmark profile from the broader database includes PassMark tests such as data compression (254215), data encryption (17434), floating point math (37049), and integer math (67083), but none of these appear in the head-to-head comparison.

Where Each One Wins

The EPYC 9654 wins in every recorded head-to-head benchmark, so its territory is clear: any workload that can use more cores, more threads, or higher per-core performance. The 96-core, 192-thread configuration with 384 MB of L3 cache and DDR5 memory bandwidth at 460.8 GB/s makes it suited for heavy multi-threaded server workloads. The Cinebench R23 multi-core score of 101675 is the strongest evidence of this.

The EPYC 7203P wins in no recorded benchmark, but it has structural advantages that are not captured in the head-to-head tests. Its TDP of 120 is one-third of the 9654's 360, which means lower cooling and power delivery requirements. Its base clock of 2.80 GHz is higher than the 9654's 2.40 GHz, which could benefit workloads that run at sustained base frequencies rather than boost states. Its DDR4 memory support and eight-channel bus are less demanding on platform design.

The 7203P also holds a launch MSRP of $348 versus the 9654's $11805. The data does not include cost-per-performance metrics, but the price difference is substantial.

For users with workloads that fit within 8 cores and 16 threads, the 7203P offers a lighter platform footprint. For users with workloads that scale to 96 cores and 192 threads, the 9654 is the only option in this comparison that can deliver the recorded performance levels.

The verdict from the data: the 9654 is the performance leader without exception in the measured tests, and the 7203P serves a different market segment defined by lower power and platform simplicity.
