Architecture Differences

The AMD EPYC 4464P belongs to the EPYC 4004 series, built on the Zen 4 architecture with the codename Raphael. It is fabricated on a 5 nm process at TSMC and uses a chiplet design with a die size of 2x 71 mm². The processor packages 13,140 million transistors and provides 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 64 MB of shared L3 cache. This is a server and workstation part, designed for AMD Socket AM5, and it includes Radeon Graphics as an integrated GPU. The EPYC 4464P supports ECC memory, which is typical for its market segment.

The Intel Core i9-13900KF is a desktop part from the Core 13th Gen series, built on the Raptor Lake architecture with the codename Raptor Lake-S. It uses Intel's 10 nm process and has a monolithic die size of 257 mm². The cache layout differs significantly: 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. That is a smaller L3 pool than the AMD chip, but the per-core L1 and L2 allocations are larger. The Intel processor supports both DDR4 and DDR5 memory, whereas the AMD chip is DDR5-only. The Intel part also has no integrated graphics, while the AMD chip includes Radeon Graphics.

The core configurations are starkly different. Intel uses a hybrid design with 24 cores and 32 threads, leveraging its performance and efficiency core arrangement. AMD's 12 cores and 24 threads are all full Zen 4 cores, which explains the higher base clock of 3.70 GHz versus Intel's 3.00 GHz. However, Intel boosts higher at 5.80 GHz. The EPYC 4464P has a locked multiplier, while the i9-13900KF is multiplier-unlocked, meaning overclocking is only possible on the Intel part. The PCIe lane counts also differ: AMD provides 28 Gen 5 lanes (CPU only), while Intel provides 20 Gen 5 lanes (CPU only).

The release timeline places the Intel chip earlier, launching in September 2022, while the AMD EPYC 4464P arrived in May 2024. The AMD part carries a launch MSRP of $429, and the Intel part has a launch MSRP of $564. Both are listed as Active in production status.

The Verdict

The data points to a clear split: the Intel Core i9-13900KF dominates in almost every measured workload, winning 16 of 17 head-to-head benchmarks. Its Cinebench R23 multi-core score of 48855 is 17.7% higher than the EPYC 4464P's 40215, and the single-core gap is identical at 17.7% (6897 versus 5677). In PassMark integer math, Intel leads by 22.5% (206859 versus 160410), and in floating-point math the margin grows to 38.3% (150869 versus 93090). Data compression also heavily favors Intel: 786218 versus 574304, a 27% difference.

The AMD EPYC 4464P is not without merit. It wins the prime number finding test by a wide margin, 343 versus 225, a 52.4% advantage. That suggests a particular strength in integer-heavy, non-vectorized workloads. The EPYC 4464P also has a higher average benchmark score (64823) than the i9-13900KF (61841), partly because its nearest rivals include the AMD EPYC 9124 and EPYC 7343, which cluster closely. The AMD chip also offers a lower base clock but a higher L3 cache (64 MB versus 36 MB), which may benefit certain server workloads.

For buyers, the choice depends on the use case. The Intel Core i9-13900KF is the better pick for general desktop performance, content creation, and any task that leverages high thread counts and high boost clocks. Its single-thread and multi-thread Cinebench results are uniformly stronger. The AMD EPYC 4464P is the more appropriate choice for server or workstation deployments where ECC memory support, a lower launch MSRP, and a lower TDP (65 W versus 125 W) matter, and where the specific prime number workload is relevant. The AMD chip also supports more PCIe lanes (28 versus 20), which could be useful for expandability in a workstation chassis.

Head-to-Head Benchmarks

The Intel Core i9-13900KF wins every Cinebench test by the same margin. In Cinebench R15 multi-core, Intel scores 4924 against AMD's 4053, a 17.7% lead. The single-core result is 695 versus 572, also 17.7%. Cinebench R20 multi-core shows 20519 versus 16890, again 17.7%. Single-core R20 is 2896 versus 2384. Cinebench R23 multi-core is 48855 versus 40215, and single-core is 6897 versus 5677. The consistency of the 17.7% delta across all Cinebench versions suggests a uniform architectural advantage for Intel in both single-threaded and multi-threaded rendering workloads.

PassMark results show a similar pattern, though with varying margins. Data compression: Intel wins 786218 to 574304, a 27% lead. Data encryption: Intel leads 46186 to 35816, a 22.5% margin. Extended instructions: Intel wins 46084 to 39359, a 14.6% gap. Floating-point math: Intel dominates 150869 to 93090, a 38.3% advantage, the largest single margin in the entire comparison. Integer math: Intel wins 206859 to 160410, a 22.5% lead. Multithread: Intel scores 57729 versus 47514, a 17.7% gap. Physics: Intel edges out AMD 2956 to 2873, a narrow 2.8% difference. Random string sorting: Intel leads 86510 to 70200, an 18.9% margin. Single-thread: Intel wins 4584 to 4146, a 9.6% gap.

The AMD EPYC 4464P's sole victory comes in the PassMark find prime numbers test. AMD scores 343 against Intel's 225, a 52.4% advantage. This is a substantial win and indicates that the AMD architecture handles this particular computational pattern significantly better. It is importantly this is a single test, and in all other recorded benchmarks, Intel holds the lead.

The overall head-to-head tally is 16 wins for Intel and 1 win for AMD. The average benchmark score, however, slightly favors AMD (64823 versus 61841), which reflects the different benchmark sets each chip carries in the database. The Intel chip's nearest rivals include the Core i9-13900K (delta 0.1%) and Core i9-13900T (delta 0.2%), while the AMD chip's nearest rivals include the Intel Core Ultra 7 265 (delta 0.3%) and the AMD EPYC 9124 (delta -0.4%). Both processors sit at the 93rd percentile among all CPUs, indicating that each is a high-end part in its respective market segment.
