AMD EPYC 4484PX vs Intel Core i7-14700KF Comparison

Where Each One Wins

The benchmark record splits these two processors into distinct usage profiles. The Intel Core i7-14700KF takes the majority of wins, claiming 14 of the 17 head-to-head comparisons. Its dominance spans rendering workloads, memory-sensitive tasks, and general multithreaded performance. The AMD EPYC 4484PX counters with three wins, and those victories cluster around specific instruction patterns and physics simulation, which hints at architectural strengths in particular computational paths.

The Intel part leads in every Cinebench test, both single-core and multi-core, across R15, R20, and R23. That consistency suggests the Core i7-14700KF delivers a balanced performance envelope that translates across generations of the Cinebench suite. The database also shows clear advantages in PassMark integer math, floating-point math, data compression, data encryption, and multithreaded workloads. For users running mixed productivity workloads, database operations, or content creation pipelines, the Intel processor is the stronger candidate based on recorded data.

The AMD EPYC 4484PX wins in PassMark extended instructions, prime number finding, and physics. The prime number result is particularly striking: the EPYC scores 425 against the Intel's 212, a 50.1% deficit for the Intel chip. Physics simulation shows a similar pattern, with the AMD part scoring 4938 versus 2961, a 40% difference. These wins point to workloads that benefit from the EPYC's large L3 cache and the 3D V-Cache slice, which accelerates repetitive data access patterns.

Architecture Differences

The two processors come from different design philosophies. The Intel Core i7-14700KF is built on Raptor Lake architecture, a 10 nm process from Intel's own foundry, and uses a hybrid core layout. It pairs 20 cores with 28 threads, meaning some cores handle multiple threads while others operate single-threaded. The base clock sits at 3.40 GHz with a boost clock of 5.60 GHz, and the TDP is 125 W. The die measures 257 mm², and the cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3.

The AMD EPYC 4484PX uses Zen 4 architecture on a 5 nm process from TSMC. It is a server and workstation part with 12 cores and 24 threads, all cores symmetric. Base clock is higher at 4.40 GHz, and the boost clock matches the Intel at 5.60 GHz. TDP is slightly lower at 120 W. The chip uses 17,840 million transistors across two dies, each 71 mm². The L1 cache is smaller at 64 KB per core, L2 is 1 MB per core, but the L3 is dramatically larger: 128 MB shared, plus a dedicated 64 MB 3D V-Cache slice. That extra cache is the defining feature of the PX variant.

Memory support also differs. The Intel part supports both DDR4 and DDR5, while the AMD part supports only DDR5. Both use dual-channel memory buses, but the AMD processor has a recorded memory bandwidth of 83.2 GB/s, a figure not listed for the Intel chip. PCIe connectivity favors the AMD part with 28 Gen 5 lanes, compared to 16 Gen 5 lanes for Intel. The AMD processor also includes integrated Radeon Graphics, while the Intel part lists no integrated graphics. Socket compatibility is entirely separate: Intel Socket 1700 for the Core i7, AMD Socket AM5 for the EPYC.

Head-to-Head Benchmarks

The Cinebench results show a consistent 2.8% advantage for the Intel Core i7-14700KF across all six tests. In R15 multi-core, the Intel scores 4452 against 4330 for the EPYC. Single-core R15 sees 628 versus 611. R20 multi-core moves to 18550 versus 18044, and R20 single-core is 2618 versus 2547. R23 multi-core reaches 44167 against 42964, and R23 single-core is 6235 versus 6065. The uniformity of that 2.8% delta across every Cinebench variant suggests a stable architectural efficiency gap rather than a workload-specific quirk.

The PassMark suite reveals larger swings. Floating-point math shows the biggest Intel win: 134393 versus 96446, a 39.3% margin. Integer math follows at 183056 versus 162993, a 12.3% advantage. Data compression yields 694963 against 603371, a 15.2% lead. Data encryption is closer, with 40046 versus 36499, a 9.7% edge. Random string sorting shows a modest 4.3% advantage at 74723 versus 71642. The multithread score lands at 52425 versus 50547, a 3.7% difference. Single-thread performance favors Intel at 4480 versus 4119, an 8.8% margin.

The AMD EPYC 4484PX wins are concentrated but decisive. Extended instructions score 43315 versus 40660, a 6.1% advantage for AMD. Prime number finding is the standout: 425 versus 212, a 50.1% gap that dwarfs any other delta in the comparison. Physics simulation shows 4938 versus 2961, a 40% difference. These three wins share a common thread: they benefit heavily from the EPYC's massive cache footprint and the 3D V-Cache slice, which keeps larger working sets resident on-chip.
