AMD EPYC 7413 vs Intel Core i9-14900KF Comparison

The AMD EPYC 7413 and Intel Core i9-14900KF are both 24-core processors, but they are engineered for entirely different environments. The EPYC is a server/workstation part with 48 threads, a 128 MB shared L3 cache, and eight-channel DDR4 memory, while the i9 is a desktop chip with 32 threads, a 6.00 GHz boost clock, and support for both DDR4 and DDR5. Benchmark results show the i9 winning 12 of 17 head-to-head tests, including every Cinebench workload, while the EPYC dominates a focused set of integer-heavy and specialized server tasks. Both CPUs sit at the 97th percentile of all processors, with average benchmark scores of 80,041 for the EPYC and 79,245 for the i9, a difference of just 1%.

Head-to-Head Benchmarks

The Intel Core i9-14900KF takes a clean sweep of the Cinebench suite. Across R15, R20, and R23, in both single-core and multi-core modes, the i9 leads by exactly 13.3% in every test. For example, in Cinebench R23 multi-core, the EPYC scores 43,044 while the i9 reaches 49,636; in single-core, the i9 posts 7,007 against the EPYC’s 6,076. This consistent 13.3% gap indicates a fundamental throughput advantage for the Intel part in rendering workloads.

The i9’s largest win comes in Passmark single-thread performance, where it scores 4,685 versus the EPYC’s 2,400 — a 48.8% lead. That is the biggest delta in the entire test set. Floating point math also heavily favors Intel: 151,918 vs 118,881, a 21.7% advantage. Data compression goes to the i9 by 8.9% (785,831 vs 715,616), and random string sorting by 6.3% (86,564 vs 81,134). The i9 also wins Passmark multithread by 13.3% (58,405 vs 50,641), matching its Cinebench margin.

The EPYC counters with its own decisive victories. The most striking is Passmark find prime numbers: 397 vs 231, a 71.9% lead for AMD. Physics simulation follows with a 49% advantage (4,708 vs 3,159). Data encryption goes to the EPYC by 4.5% (48,492 vs 46,416), extended instructions by 1.9% (45,696 vs 44,839), and integer math by 3.1% (215,629 vs 209,125). These wins are concentrated in workloads that stress integer arithmetic, memory bandwidth, and large cache residency.

Where Each One Wins

The EPYC 7413 is clearly the better processor for server-side and scientific computing tasks. Its 71.9% margin in prime number finding points to superior integer throughput and memory latency characteristics for iterative, cache-resident algorithms. The 49% physics lead suggests strong simulation performance, likely aided by the 128 MB L3 cache and eight-channel memory interface (204.8 GB/s). Data encryption, extended instructions, and integer math all favor AMD, making the EPYC a natural fit for cryptography, database workloads, and high-performance computing that relies on large working sets.

The i9-14900KF wins everywhere else. All Cinebench tests, which are heavily multithreaded but also depend on high clock speeds and floating-point units, go to Intel. The 21.7% floating point math advantage is substantial, and the 48.8% single-thread lead makes the i9 ideal for desktop applications, gaming, and any latency-sensitive code. Data compression and random string sorting also favor the i9, indicating strong general-purpose performance. For a desktop user who does rendering, content creation, or everyday multitasking, the i9 is the clear choice.

In summary, the EPYC wins where large caches and memory bandwidth matter: encryption, prime number searches, physics simulation, and integer-heavy workloads. The i9 wins where clock speed and floating-point throughput dominate: rendering, single-threaded apps, and general productivity.

Architecture Differences

The two CPUs are built on fundamentally different designs. The AMD EPYC 7413 uses the Zen 3 architecture on a 7 nm TSMC process, with a die size of 4x 81 mm². It features 24 cores and 48 threads via simultaneous multithreading, with a base clock of 2.65 GHz and a boost of 3.60 GHz. The TDP is 180 W. It supports DDR4 memory on an eight-channel bus, delivering 204.8 GB/s of bandwidth, and includes ECC. PCIe is Gen 4 with 128 lanes.

The Intel Core i9-14900KF is based on Raptor Lake on Intel’s 10 nm process, with a die size of 257 mm². It has 24 cores and 32 threads (a mix of performance and efficiency cores, though the exact split is not specified in the data). Base clock is 3.20 GHz, boost is 6.00 GHz, and TDP is 125 W. It supports both DDR4 and DDR5 on a dual-channel bus, with ECC enabled. PCIe is Gen 5 with 16 lanes. The i9 also has an unlocked multiplier, while the EPYC does not.

Cache structures differ markedly. The EPYC provides 64 KB L1 and 512 KB L2 per core, with a shared 128 MB L3. The i9 offers 80 KB L1 and 2 MB L2 per core, but only 36 MB of shared L3. The EPYC’s massive L3 is designed to feed 48 threads and reduce memory traffic, while the i9’s smaller cache relies on higher clock speeds to compensate.
