Analysis: AMD EPYC 9335 vs AMD EPYC 9565
The AMD EPYC 9565 and AMD EPYC 9335 are both members of the EPYC 9005 series, built on the Zen 5 architecture and the 4 nm process from TSMC. They share the same AMD Socket SP5, twelve-channel DDR5 memory support, and 128 PCIe Gen 5 lanes. Despite these similarities, the two processors occupy very different positions in the server lineup: the 9565 is a 72-core flagship with a 400 W TDP, while the 9335 is a 32-core part with a 210 W TDP. Benchmark results from the database show that the 9565 wins every recorded head-to-head test, often by very large margins.
The Verdict
The verdict is unambiguous: the EPYC 9565 is the performance leader, winning all 11 head-to-head benchmarks. It delivers a 105.5% higher multithread score and a 35.3% higher single-thread score than the 9335. For workloads that scale across many cores, such as data compression, encryption, and floating-point math, the 9565 is the definitive choice. The 9335, while still a high-performance server CPU in the 99th percentile of all CPUs, is best suited for environments where the lower 210 W TDP and fewer cores are priorities, but it cannot match the 9565 in any measured metric. The 9335 does have a higher boost clock (4.40 GHz vs 4.30 GHz) and a lower launch MSRP ($3178 vs $10486), but the recorded data shows no performance advantage from these factors.
Architecture Differences
Both processors are built on the same Zen 5 architecture and 4 nm process, with identical memory and PCIe capabilities. The primary differences lie in the silicon configuration. The 9565 uses 12 chiplets, each 70.6 mm², totaling 99,780 million transistors, while the 9335 uses 4 chiplets of the same size, with 33,260 million transistors. This translates to 72 cores and 144 threads for the 9565 versus 32 cores and 64 threads for the 9335. The L3 cache is 384 MB shared on the 9565 and 128 MB on the 9335. Base clocks differ: 3.15 GHz for the 9565 and 3.00 GHz for the 9335, while boost clocks are 4.30 and 4.40 GHz respectively. TDP is 400 W for the 9565 and 210 W for the 9335. Both support DDR5 with twelve-channel memory and 576.0 GB/s bandwidth, and both have 128 PCIe Gen 5 lanes. The 9565 also has a larger die footprint (12x 70.6 mm² vs 4x 70.6 mm²), which aligns with its higher transistor count and core count.
Where Each One Wins
In every benchmark recorded, the 9565 outperforms the 9335. The largest margins are in physics (846.8% higher score) and prime number finding (612.4% higher). Floating-point math is 140.8% higher, random string sorting 150.4% higher, data encryption 124.7% higher, and data compression 114.4% higher. Integer math is 107.3% higher, and multithread is 105.5% higher. The smallest gap is in single-thread performance, where the 9565 leads by 35.3%. The 9335's only advantages are its lower TDP and higher boost clock, but the benchmark data shows no workload where it comes out ahead. For users prioritizing raw throughput across many threads, the 9565 is the only choice. For those who need a lower thermal envelope, the 9335 is a viable alternative, but it sacrifices substantial performance in every tested category.
