AMD EPYC 7F72 vs Intel Core i9-14900KS Comparison

The AMD EPYC 7F72 and Intel Core i9-14900KS are both 24-core processors, but they are engineered for entirely different worlds. The EPYC is a server/workstation part built for massive data throughput and sustained loads, while the i9 is a desktop flagship designed for maximum clock speed and responsiveness. The benchmark data shows a clear split: Intel wins the majority of the head-to-head tests (11 wins to AMD's 6), but AMD secures decisive victories in specialized workloads that reveal its enterprise DNA. With both processors scoring in the 96th percentile of all CPUs, the choice is not about overall capability but about which niche you prioritize.

The Verdict

The data paints a straightforward picture for two distinct audiences. For anyone building a high-end desktop, the Intel Core i9-14900KS is the obvious pick. It wins every Cinebench test, from single-core to multi-core, and dominates in general-purpose math and multithreaded tasks. Its single-thread score is more than double the EPYC's, and it leads by 12.1% in multi-core Cinebench R23. This is the processor for gaming, content creation, and any workload that rewards high clock speeds and strong single-thread performance.

The AMD EPYC 7F72 is the choice for a server room, not a gaming rig. It is not faster in most traditional benchmarks, but it wins where data movement matters: encryption (17.9% ahead), random string sorting (14.1% ahead), and prime number finding (a staggering 104.1% ahead). Its 192 MB of shared L3 cache and eight-channel memory bus are built for massive datasets and concurrent virtual machines. The EPYC also carries a 240W TDP versus Intel's 150W, reflecting its focus on sustained, throughput-oriented operation rather than burst performance. If you need a server CPU that excels at database work, cryptography, or scientific computing, the EPYC is the data-backed winner.

Where Each One Wins

Intel Core i9-14900KS wins in all rendering and general compute tests. In Cinebench R15, R20, and R23, it leads by a consistent 12.1% in both single-core and multi-core scores. The i9 also takes PassMark's integer math (14.8% ahead), floating-point math (29.6% ahead), and the overall multithread benchmark (12.1% ahead). The single-thread test is its biggest margin of victory, with a score of 4,815 versus the EPYC's 2,384, a 50.5% lead. This is a processor that simply runs faster on a clock-for-clock basis, with a 6.20 GHz boost clock driving its performance.

AMD EPYC 7F72 wins in data-centric and specialized workloads. Its PassMark data encryption score of 56,261 is 17.9% higher than Intel's 47,717, and its random string sorting score is 14.1% higher. The prime number finding test is not even close: the EPYC scores 498 versus Intel's 244, a 104.1% advantage. The EPYC also wins the physics test by 91% (6,459 vs 3,381) and shows a small edge in data compression (0.7%) and extended instructions (3.1%). These wins point to a CPU with massive cache capacity and memory bandwidth that excels at algorithms with large working sets.

Architecture Differences

The two processors are built on fundamentally different foundations. The AMD EPYC 7F72 uses the Zen 2 architecture on a 7nm TSMC process, with a die size of just 74 mm² and 3,800 million transistors. It is a server part on the AMD Socket SP3 platform with eight-channel DDR4 memory support and a memory bandwidth of 204.8 GB/s. Its cache hierarchy is notable: 96 KB L1 per core, 512 KB L2 per core, and a massive 192 MB of shared L3 cache. It supports ECC memory and PCIe Gen 4, with no integrated graphics. The EPYC has a base clock of 3.20 GHz and a boost clock of 3.70 GHz, which is modest compared to Intel but emphasizes efficiency and scalability.

The Intel Core i9-14900KS uses the Raptor Lake architecture on Intel's 10nm process, with a die size of 257 mm². It fits the Intel Socket 1700 platform and supports both DDR4 and DDR5 memory, though it is limited to dual-channel memory. Its cache is much smaller: 80 KB L1 per core, 2 MB L2 per core, and 36 MB of shared L3. It includes integrated UHD Graphics 770 and supports PCIe Gen 5 with 16 CPU lanes. The i9 has a base clock of 3.20 GHz but a boost clock of 6.20 GHz, enabling the high single-thread performance seen in the benchmarks. It is multiplier-unlocked for overclocking, while the EPYC is not. The i9 also has more threads per core? No—the EPYC has 48 threads (24 cores) while the i9 has 32 threads (24 cores), meaning the EPYC supports simultaneous multithreading on all cores while the i9 likely uses a hybrid approach with efficiency cores.

Head-to-Head Benchmarks

The data reveals a consistent pattern in Cinebench: the Intel i9-14900KS wins every single test by the same 12.1% margin. In Cinebench R23 multi-core, the i9 scores 50,995 versus the EPYC's 44,829. The single-core R23 test shows 7,199 vs 6,328. This consistency suggests a fundamental clock speed advantage rather than a workload-specific one. The i9's 6.20 GHz boost clock compared to the EPYC's 3.70 GHz explains this uniform lead.

The PassMark suite shows a more complex picture. The Intel i9 takes the overall multithread test (60,012 vs 52,740, a 12.1% lead), integer math (212,644 vs 181,103, a 14.8% lead), and floating-point math (153,975 vs 108,437, a 29.6% lead). These are significant wins in general compute. However, the EPYC strikes back in specific areas. Its data encryption score of 56,261 beats Intel's 47,717 by 17.9%. The random string sorting test shows a 14.1% lead for AMD (102,436 vs 89,789). The find prime numbers test is the most lopsided: AMD scores 498, Intel scores 244, a 104.1% difference. The physics test also favors AMD by 91% (6,459 vs 3,381). The EPYC's data compression score of 808,795 just edges out Intel's 803,368 by 0.7%.

The single-thread PassMark test is the largest margin of victory for Intel. The i9 scores 4,815, more than double the EPYC's 2,384. This 50.5% gap highlights the fundamental difference in design philosophy: Intel prioritizes raw clock speed for desktop responsiveness, while AMD prioritizes cache capacity and memory bandwidth for server throughput. The EPYC's 192 MB of L3 cache and eight-channel memory bus are clearly effective for data-heavy workloads, as shown by its wins in encryption, sorting, and prime number calculation. The i9's smaller 36 MB L3 cache and dual-channel memory limit its performance in these areas but allow for much higher clock speeds. Ultimately, the benchmark data shows both processors are in the top 4% of all CPUs, but they excel in opposite directions.
