AMD EPYC 7D12 vs AMD EPYC 9224 Comparison

The Verdict

The recorded data is unambiguous: the AMD EPYC 9224 wins every single benchmark in the head-to-head comparison against the AMD EPYC 7D12. Across all six Cinebench tests, the EPYC 9224 holds a consistent 5.4% advantage over the EPYC 7D12. For workloads that rely on single-threaded performance or modern architectural features, the EPYC 9224 is the clear choice. The EPYC 7D12, however, offers a different trade-off: it packs 32 cores and 64 threads compared to 24 cores and 48 threads, while drawing only 85W of power versus 200W. The data suggests the EPYC 7D12 is for high-density, power-conscious deployments where core count matters more than per-core speed. The EPYC 9224 is for those who need the fastest possible Cinebench results and can accommodate the newer platform requirements.

Where Each One Wins

The EPYC 9224 wins in every measured category. Its advantage is uniform at 5.4% across both single-core and multi-core tests. This consistency is notable: the newer Zen 4 architecture does not merely scale better with more threads, it also improves single-threaded performance by the same margin. The EPYC 9224 reaches a boost clock of 3.70 GHz compared to 3.00 GHz on the EPYC 7D12, and its base clock of 2.50 GHz is more than double the 7D12's 1100.00 MHz base. For database servers, virtualization hosts, or any workload where each thread's raw speed matters, the EPYC 9224 is the superior part.

The EPYC 7D12 wins on efficiency and raw core density, though not on benchmark scores. It offers 32 cores and 64 threads, which is 33% more cores and 33% more threads than the EPYC 9224's 24 cores and 48 threads. Yet it still loses the multi-core tests by 5.4%. This means the 7D12's extra cores do not compensate for the lower clock speeds and older Zen 2 design. The 7D12's 85W TDP is less than half of the 9224's 200W TDP, making it the choice for power-constrained racks. If the workload is massively parallel but latency-tolerant, and the power budget is tight, the 7D12's core count could be attractive, even though the benchmark data shows it is slower in every measured test.

Architecture Differences

The two processors come from different generations and platforms. The EPYC 9224 is part of the EPYC 9004 series, built on Zen 4 architecture with the codename Genoa. It uses a 5 nm process node from TSMC and packs 26,280 million transistors across a die size of 4x 72 mm². The EPYC 7D12 belongs to the Zen 2 generation, codenamed Rome, fabricated on a 7 nm process with 15,200 million transistors and a die size of 4x 74 mm². The transistor count difference is substantial: the 9224 has over 70% more transistors than the 7D12.

Cache hierarchies also differ. The EPYC 9224 has 64 KB of L1 and 1 MB of L2 per core, with 64 MB of shared L3 cache. The EPYC 7D12 also has 64 KB of L1 per core, but only 512 KB of L2 per core, and its L3 is organized as 32 MB per die, totaling 128 MB across the chip. The 9224's larger per-core L2 is likely a factor in its single-core advantage, while the 7D12's larger total L3 could help in some multi-threaded scenarios, though the benchmark data does not reflect a win for the 7D12.

Memory and I/O platforms diverge completely. The EPYC 9224 requires AMD Socket SP5 and supports DDR5 memory with a twelve-channel memory bus, delivering 460.8 GB/s of bandwidth. The EPYC 7D12 uses AMD Socket SP3, supports DDR4 with an eight-channel bus, and provides 204.8 GB/s. The 9224 offers PCIe Gen 5 with 128 lanes, while the 7D12 offers PCIe Gen 4 with 128 lanes. Both support ECC memory. The 9224 released on 2022-11-09, while the 7D12 launched on 2020-04-13. The EPYC 9224 has a launch MSRP of $1825; no launch MSRP is recorded for the EPYC 7D12.

Head-to-Head Benchmarks

The head-to-head data is remarkably consistent. In every Cinebench test, the EPYC 9224 wins with a delta of 5.4%. Starting with Cinebench R15 multi-core, the 9224 scores 3874 against 3675 for the 7D12. In R15 single-core, it is 546 versus 518. Moving to Cinebench R20, the 9224 records 16144 in multi-core and 2278 in single-core, while the 7D12 records 15315 and 2162 respectively. The pattern holds in Cinebench R23: 38439 multi-core and 5426 single-core for the 9224, against 36465 and 5148 for the 7D12.

The identical 5.4% delta across all tests is a strong signal. The performance gap is not dependent on thread scaling or workload type. It is a per-clock, per-core architectural advantage. The 9224's higher boost clock, newer Zen 4 cores, and faster memory subsystem all contribute. The 7D12's larger core count is insufficient to overcome the gap, even in the multi-core tests where extra threads should help. The 7D12 has 33% more cores, yet it is 5.4% slower in multi-core Cinebench. This indicates that the 9224's per-core performance is so much higher that it more than compensates for the core deficit.

The average benchmark scores reflect the same story. The EPYC 9224 has an average benchmark score of 11118, while the EPYC 7D12 has 10547. The 9224 sits at the 66th percentile among all CPUs, and the 7D12 also sits at the 66th percentile. Their nearest rivals in the database confirm the positioning: the 9224 is within 0.6% of the AMD EPYC 7542, Intel Core i7-6700, AMD Ryzen 5 3500U, and Intel Xeon Gold 6336Y. The 7D12 is within 1.9% of the Intel Core i7-4790, AMD EPYC 7502P, Intel Xeon W-3175X, and Intel Xeon Gold 6338N. Both processors are mid-pack performers in the broader CPU landscape.
