Head-to-Head Benchmarks

The most decisive wins belong to the EPYC 9175F. In PassMark find prime numbers, the EPYC scores 806 against the i9-14900KS's 247—a 226.3% gap. This is not a marginal difference; it reflects fundamental architectural efficiency in integer-heavy, branch-heavy loops. Similarly, PassMark physics shows the EPYC at 8960 vs 3485, a 157.1% lead. These are workloads where the EPYC's Zen 5 architecture and massive L3 cache (512 MB shared) allow it to process more instructions per clock. The extended instructions test reinforces this: 67013 vs 45714, a 46.6% advantage for AMD. For any HPC-style computation, the EPYC is the runaway choice.

The Cinebench suite tells a consistent story. Across R15, R20, and R23, both multi-core and single-core tests, the EPYC 9175F wins every time by 8.6% to 8.7%. For example, Cinebench R23 multi-core: EPYC 55923 vs i9-14900KS 51470. Cinebench R23 single-core: EPYC 7895 vs i9-14900KS 7266. This is surprising for a chip with fewer cores, but the EPYC's higher base clock (4.20 GHz vs 3.20 GHz) and superior per-core IPC compensate. The i9-14900KS boosts to 6.20 GHz, yet it still trails in these tests—indicating that raw clock speed is not enough to overcome architectural differences.

The i9-14900KS fights back in PassMark single-thread, where it scores 4827 vs 4271 (an 11.5% win). Data encryption also goes to Intel: 48201 vs 40719, a 15.5% margin. Floating-point math falls to Intel (154565 vs 144014, 6.8%), and integer math is a near-tie (214056 vs 213518, 0.3% for Intel). Random string sorting is Intel's by 1.5% (90393 vs 89075). These wins are real but narrower in percentage terms than the EPYC's biggest victories. The EPYC's wins in prime numbers (226.3%) and physics (157.1%) dwarf Intel's best margins.

PassMark multithread shows the EPYC ahead at 65792 vs 60552, an 8.7% lead. Data compression is close but favors AMD: 835298 vs 808722, a 3.3% margin. Overall, the EPYC wins 11 of 17 benchmarks, with the i9-14900KS taking 6. The average scores reflect this: EPYC 92399, i9-14900KS 89701, a 3% delta.

Specification Differences

The two processors diverge sharply in nearly every specification. The AMD EPYC 9175F has 16 cores and 32 threads, while the Intel Core i9-14900KS has 24 cores and 32 threads. Base clocks differ: EPYC at 4.20 GHz, i9-14900KS at 3.20 GHz. Boost clocks are reversed: EPYC peaks at 5.00 GHz, i9-14900KS reaches 6.20 GHz. Thermal design power is 320 W for the EPYC and 150 W for the i9-14900KS—the EPYC draws twice the power budget. Sockets are incompatible: AMD Socket SP5 for the EPYC, Intel Socket 1700 for the i9-14900KS. The EPYC supports only DDR5 memory across a twelve-channel bus (576.0 GB/s bandwidth), while the i9-14900KS supports both DDR4 and DDR5 on a dual-channel bus with no bandwidth listed. PCIe connectivity favors the EPYC massively: 128 Gen 5 lanes vs 16 Gen 5 lanes. The i9-14900KS includes integrated UHD Graphics 770; the EPYC has no integrated graphics. The i9-14900KS has an unlocked multiplier; the EPYC does not. Process nodes differ: EPYC on TSMC 4 nm, i9-14900KS on Intel 10 nm.

Architecture Differences

The EPYC 9175F is built on Zen 5 architecture (codename Turin, part of the EPYC Zen 5 generation), fabricated on a 4 nm process by TSMC. The i9-14900KS uses Raptor Lake architecture (codename Raptor Lake-R, part of the Core i9 Raptor Lake Refresh generation), fabricated on a 10 nm process by Intel. The process node difference is significant: TSMC's 4 nm allows for higher transistor density and lower power per transistor, which helps explain the EPYC's higher base clock despite a higher TDP. The EPYC's transistor count is listed at 133,040 million, spread across 16 chiplets (16x 70.6 mm² each). The i9-14900KS is a monolithic die of 257 mm² with no transistor count provided. Cache architecture differs fundamentally: the EPYC has 512 MB of shared L3 cache, a massive pool designed for server workloads with large working sets; the i9-14900KS has 36 MB of shared L3, typical for a desktop part. Per-core L2 is 2 MB on the i9-14900KS versus 1 MB on the EPYC, suggesting Intel favors faster per-core cache access while AMD relies on the massive L3. The EPYC supports twelve-channel memory, enabling 576.0 GB/s bandwidth; the i9-14900KS's dual-channel setup is far narrower. Both support ECC memory. The EPYC has no integrated graphics, while the i9-14900KS includes UHD Graphics 770. The EPYC is a server/workstation part with 128 PCIe Gen 5 lanes; the i9-14900KS is a desktop part with 16 lanes. The EPYC's multiplier is locked; the i9-14900KS is unlocked for overclocking. These are not just different chips—they are different classes of silicon, optimized for different environments.

The Verdict

The data points to a clear split based on use case. If the workload is multi-threaded, cache-hungry, or compute-intensive—think rendering, scientific simulation, virtualization, or large-scale data processing—the AMD EPYC 9175F is the superior choice. It wins all Cinebench multi-core tests by 8.7%, dominates prime number finding by 226.3%, physics by 157.1%, and extended instructions by 46.6%. Its 512 MB L3 cache and 576.0 GB/s memory bandwidth are unmatched by the i9-14900KS. The EPYC also wins 11 of 17 head-to-head benchmarks and holds a 3% higher average benchmark score. This is the chip for a server rack or a workstation where raw throughput is king.

If the priority is single-thread responsiveness, desktop interactivity, or workloads that depend on a single fast core, the Intel Core i9-14900KS is the better pick. It leads in PassMark single-thread by 11.5% (4827 vs 4271), data encryption by 15.5%, and floating-point math by 6.8%. Its 6.20 GHz boost clock is the highest in this comparison, and its 150 W TDP is less than half the EPYC's 320 W. For a gaming PC or a desktop that runs office apps, the i9-14900KS will feel faster per core and is far easier to cool and power. The i9-14900KS also has an unlocked multiplier, allowing overclocking, and includes integrated graphics—features the EPYC lacks.

Choose the EPYC 9175F for servers, workstations, and sustained all-core workloads. Choose the i9-14900KS for desktop use where single-thread speed and lower power draw matter more than brute multi-core throughput. Both sit at the 98th percentile
