AMD EPYC 4344P vs Intel Core i5-14600 Comparison

The Intel Core i5-14600 and AMD EPYC 4344P are near-perfect statistical twins, separated by a single point in average benchmark score (45,594 vs 45,586). The data reveals a fascinating split: the EPYC 4344P dominates the Cinebench suite and most Passmark workloads, while the i5-14600 wins decisively in floating-point math, integer math, and single-threaded Passmark tests. With both CPUs sitting at the 92nd percentile and a 0% deltaPct between them, this comparison comes down to workload-specific strengths rather than overall performance supremacy.

Head-to-Head Benchmarks

The AMD EPYC 4344P wins 12 of 17 head-to-head benchmarks, but the margins tell a more nuanced story. In Cinebench, the EPYC wins every single test by a narrow 1.2-1.3% margin. The R23 multi-core score of 28,636 versus 28,271, the R20 multi-core of 12,027 versus 11,873, and the R15 multi-core of 2,886 versus 2,849 all show the EPYC ahead by a hair. The single-core Cinebench results follow the same pattern: R23 at 4,042 vs 3,991, R20 at 1,697 vs 1,676, and R15 at 407 vs 402. These are margins that would be imperceptible in real-world use, but they are consistent across every Cinebench iteration.

The EPYC's biggest wins come in Passmark's extended instructions test, where it scores 30,170 against Intel's 23,420 — a 22.4% advantage. This is the largest delta in the entire comparison and indicates a substantial lead in workloads that leverage advanced CPU instruction sets. The EPYC also wins random string sorting by 13.5% (49,001 vs 42,402) and find prime numbers by 17.6% (170 vs 140). Data encryption shows a 5.7% EPYC lead (24,648 vs 23,233), while data compression is 2.6% ahead (407,933 vs 397,167). The Passmark multi-thread score slightly favors the EPYC at 33,690 vs 33,242, a 1.3% margin.

The Intel Core i5-14600's wins are fewer but more dramatic. In Passmark floating-point math, the Intel chip scores 82,557 against the EPYC's 64,245 — a commanding 28.5% lead. This is the largest win for either side and suggests Intel's architecture handles floating-point calculations far more efficiently. Integer math also favors Intel at 113,569 vs 106,272, a 6.9% advantage. The Passmark single-thread score goes to Intel by 15% (4,094 vs 3,560), and the physics test shows Intel ahead by 4.6% (2,118 vs 2,025). These wins indicate that in specific computational domains, the i5-14600 is substantially stronger despite losing the overall benchmark count.

The Verdict

The data presents a clear split personality. For general multi-threaded rendering and encoding workloads, the AMD EPYC 4344P is the safer pick — it wins every Cinebench test and the Passmark multi-thread score, albeit by slim margins. The EPYC's 22.4% lead in extended instructions and 17.6% lead in prime number finding make it the choice for specialized compute tasks that leverage those instruction paths.

The Intel Core i5-14600 is the pick for floating-point-heavy applications and single-threaded performance. Its 28.5% advantage in floating-point math is massive, and the 15% lead in Passmark single-thread score means snappier response in lightly-threaded tasks. The integer math win of 6.9% also makes Intel the better option for general office productivity and database-style integer workloads.

Neither CPU has a meaningful overall advantage — the 0% deltaPct and 92nd percentile ranking for both confirm they are equals in aggregate performance. Choose the EPYC for consistent multi-threaded wins and instruction-heavy workloads. Choose the i5-14600 for floating-point dominance and single-thread responsiveness. If your workload involves both equally, the decision is a coin flip.

Specification Differences

The two CPUs differ in nearly every fundamental specification. The Intel Core i5-14600 features 14 cores and 20 threads, while the AMD EPYC 4344P offers 8 cores and 16 threads. Clock speeds favor the EPYC: base clock of 3.80 GHz versus 2.70 GHz, and boost clock of 5.30 GHz versus 5.20 GHz. Both have a 65W TDP.

Socket compatibility diverges completely: Intel uses Socket 1700, while AMD uses Socket AM5. Memory support differs, with Intel supporting both DDR4 and DDR5, while AMD supports only DDR5. Both are dual-channel, but the EPYC's memory bandwidth is rated at 83.2 GB/s, a figure not provided for the Intel chip. The EPYC provides 28 PCIe Gen 5 lanes (CPU only) versus Intel's 16 Gen 5 lanes. Integrated graphics differ: Intel has UHD Graphics 770, AMD has Radeon Graphics. The Intel chip has a launch MSRP of $255, while the EPYC's launch MSRP is $329. The i5-14600 launched on 2024-01-07, and the EPYC on 2024-05-20. Intel's die size is 257 mm², while AMD's is 71 mm².

Architecture Differences

The architectures are generations apart. Intel uses Raptor Lake (Raptor Lake-R refresh) on a 10 nm process built by Intel, while AMD uses Zen 4 (Raphael codename) on a 5 nm process built by TSMC. The EPYC has 6,570 million transistors on its 71 mm² die, while Intel's transistor count is not listed for its 257 mm² die.

Cache structures differ significantly. Intel allocates 80 KB L1 per core and 2 MB L2 per core, with 24 MB shared L3. AMD allocates 64 KB L1 per core and 1 MB L2 per core, but 32 MB shared L3. The larger L3 cache on the EPYC likely contributes to its wins in data-heavy workloads like compression and string sorting.

Market positioning separates them: Intel targets Desktop with its Core i5 branding, while AMD positions the EPYC for Server/Workstation use. Both support ECC memory, a rarity for desktop CPUs. Neither has an unlocked multiplier. The EPYC's smaller 5 nm process and higher transistor density on a smaller die suggest a more modern manufacturing approach, while Intel's larger 10 nm die with more cores relies on a different design philosophy.

Where Each One Wins

The AMD EPYC 4344P wins in rendering and encoding workloads, as evidenced by its 1.3% lead across all Cinebench multi-core tests. It also wins in data compression (2.6%), data encryption (5.7%), extended instructions (22.4%), prime number finding (17.6%), and random string sorting (13.5%). The Passmark multi-thread score also goes to AMD by 1.3%. This makes the EPYC the stronger choice for server-side workloads, database operations, compression tasks, and any compute that benefits from the larger 32 MB L3 cache and advanced instruction support.

The Intel Core i5-14600 wins in floating-point math by 28.5%, integer math by 6.9%, physics simulation by 4.6%, and single-threaded Passmark performance by 15%. These wins point to applications like scientific computing, financial modeling, physics engines, and lightly-threaded desktop applications where single-core speed matters. The 14-core/20-thread configuration gives Intel more raw thread count, yet it still trails in most multi-threaded tests, suggesting the EPYC's architecture extracts more work per thread. For builders prioritizing floating-point throughput or the fastest possible single-threaded Passmark score, the i5-14600 is the clear winner despite losing the majority of benchmark battles.
