AMD EPYC 4345P vs Intel Core i5-14600KF Comparison

The Intel Core i5-14600KF and AMD EPYC 4345P are both 90th-percentile CPUs, but they achieve that status through very different designs. The Intel part, a 14-core desktop chip with an unlocked multiplier, edges out the AMD EPYC in overall average benchmark score, posting 49394 against 48470. The EPYC, a server/workstation part with just 8 cores, counters with a higher boost clock and a more efficient process node. The data shows the Intel chip wins 12 of the 17 head-to-head tests, making it the broader performer, while the AMD chip takes 5 specific efficiency and single-thread tests. The choice between them comes down to workload priorities: the i5-14600KF dominates heavily in data compression, encryption, and floating-point math, while the EPYC 4345P leads in extended instructions, prime number finding, physics, and raw single-thread PassMark scores.

The Verdict

The Intel Core i5-14600KF is the default pick for most desktop users and content creators. It wins the vast majority of head-to-head matchups, and its victories are often decisive—25.3% ahead in floating-point math and 18.4% ahead in data encryption. It also holds a 1.6% lead across every Cinebench R15, R20, and R23 test, both single-core and multi-core. Its average benchmark score of 49394 places it just 0.3% above the AMD Ryzen 9 7900, confirming it trades blows with a 12-core rival. With a launch MSRP of $294 and an unlocked multiplier, it is the clear choice for a high-performance desktop build.

The AMD EPYC 4345P, with a launch MSRP of $329, is the pick for server or workstation environments where its specific strengths matter. It wins the PassMark single-thread test by 3.1% (4408 vs 4273) and the physics test by 5.2% (2583 vs 2449). It also leads in extended instructions by 9.1% and prime number finding by 3.6%. These are not headline-grabbing margins, but they are consistent across a cluster of tests that point to efficiency in certain mathematical and instruction-heavy workloads. Its 65W TDP, versus the Intel chip’s 125W, also signals a major power efficiency advantage that is critical for dense server deployments.

Do not pick the EPYC for raw multi-threaded rendering; it loses every Cinebench multi-core test to the i5. Do not pick the Intel chip for a low-power server where the EPYC’s PassMark wins and lower TDP are more relevant. The data is unambiguous: the i5-14600KF is the generalist winner, and the EPYC 4345P is the specialist in a narrow but real niche.

Where Each One Wins

The Intel Core i5-14600KF wins every Cinebench test, from R15 multi-core (3280 vs 3227) to R23 single-core (4594 vs 4520). This indicates a consistent advantage in both short and long render workloads. It also wins PassMark multithread by 7.1% (38697 vs 36123), and its biggest wins come in data compression (15.1% ahead), data encryption (18.4% ahead), floating-point math (25.3% ahead), and random string sorting (12.6% ahead). These are classic desktop and content-creation workloads—compressing files, encrypting data, and processing media—where the Intel chip’s 14 cores and 20 threads provide a substantial edge.

The AMD EPYC 4345P wins the PassMark single-thread test by 3.1% (4408 vs 4273), a notable result given its lower core count. It also wins the physics test by 5.2% (2583 vs 2449), the extended instructions test by 9.1% (31663 vs 28785), and the prime number finding test by 3.6% (167 vs 161). These wins suggest a design optimized for instruction-level parallelism and specific mathematical operations, not for brute-force multi-threading. The EPYC’s 5.50 GHz boost clock, higher than the Intel’s 5.30 GHz, likely contributes to its single-thread superiority.

The split is clear: Intel wins where parallel throughput and memory-heavy operations are involved; AMD wins where single-thread latency and specialized instruction execution matter. If the workload involves rendering, compression, or encryption, the i5 is the answer. If it involves physics simulation or extended instruction sets, the EPYC has the edge.

Architecture Differences

The two chips come from opposite ends of the design spectrum. The Intel Core i5-14600KF uses the Raptor Lake architecture on a 10 nm process fabricated by Intel, with a die size of 257 mm². It packs 14 cores and 20 threads, with a base clock of 3.50 GHz and a boost clock of 5.30 GHz. Its cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3. It supports both DDR4 and DDR5 memory on a dual-channel bus, and it has 16 PCIe Gen 5 lanes from the CPU. It includes an unlocked multiplier, making it overclockable, and ships with no integrated graphics.

The AMD EPYC 4345P uses the Zen 5 architecture on a 4 nm process fabricated by TSMC, with a much smaller die size of 70.6 mm² and 8,315 million transistors. It has 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 5.50 GHz. Its cache includes 80 KB of L1 per core, 1 MB of L2 per core, and a larger 32 MB of shared L3. It supports only DDR5 memory on a dual-channel bus, with a memory bandwidth of 89.6 GB/s. It provides 24 PCIe Gen 5 lanes from the CPU and includes Radeon Graphics as integrated graphics. The multiplier is locked.

The process node difference is stark: 10 nm Intel versus 4 nm TSMC. This explains the EPYC’s much lower 65W TDP compared to the Intel’s 125W, despite the EPYC having a higher boost clock. The Intel chip compensates with more cores and threads, plus a larger L2 cache per core. The EPYC counters with a larger L3 cache (32 MB vs 24 MB) and more PCIe lanes (24 vs 16). Both support ECC memory, and both are currently in active production. The Intel chip launched in October 2023, while the EPYC arrived much later in May 2025.

Head-to-Head Benchmarks

The biggest win for the Intel Core i5-14600KF is in PassMark floating-point math, where it scores 93048 against the EPYC’s 74255—a decisive 25.3% advantage. This is the largest margin in the entire head-to-head set and signals a major strength in scientific and media workloads that rely on heavy FPU usage. The second-largest Intel win is in data encryption, with a score of 27608 versus 23313, an 18.4% lead. This is followed by data compression (485140 vs 421490, 15.1% ahead) and random string sorting (52056 vs 46238, 12.6% ahead). These four tests alone establish the Intel chip as the clear winner for security, data handling, and number-crunching tasks.

The AMD EPYC 4345P’s biggest win is in PassMark extended instructions, where it scores 31663 against the Intel’s 28785—a 9.1% lead. This suggests the EPYC’s Zen 5 architecture handles advanced instruction sets more efficiently. Its other wins are narrower: physics (2583 vs 2449, 5.2% ahead), prime number finding (167 vs 161, 3.6% ahead), and single-thread (4408 vs 4273, 3.1% ahead). The single-thread win is particularly interesting because the Intel chip wins every Cinebench single-core test—the EPYC’s PassMark single-thread advantage does not translate to Cinebench R15, R20, or R23, where the Intel chip leads by 1.5% to 1.6% in each case.

The Cinebench results are uniform: the Intel chip wins all six tests (R15, R20, R23, each in single and multi-core) by exactly 1.5% or 1.6%. This consistency indicates a stable performance advantage across rendering generations. The PassMark multithread test also goes to Intel, with 38697 versus 36123, a 7.1% margin. The only Intel loss in a multithreaded context is absent—the EPYC’s wins are all in single-thread or specialized instruction tests. This pattern reinforces that the Intel chip’s 14 cores provide a tangible multi-threaded edge over the EPYC’s 8 cores, despite the EPYC’s higher boost clock and more advanced process node.
