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

The Intel Core i7-14700K and the AMD EPYC 4484PX are both 94th-percentile CPUs, but they achieve that standing through fundamentally different strengths. The Intel part dominates in raw throughput across a wide range of workloads, while the AMD EPYC counters with massive single-thread leads and a handful of specialized server-oriented victories. The head-to-head data shows 11 wins for the Intel Core i7-14700K and 6 for the AMD EPYC 4484PX, yet the margin of those wins tells a more complex story about which processor suits which task.

Where Each One Wins

The Intel Core i7-14700K is the clear winner in general-purpose multi-threaded work and integer-heavy tasks. It takes the Cinebench R15 multicore test with a score of 5035 against 4330, a 16.3% advantage. The lead persists in Cinebench R20 multicore, though narrower at 2.8% (18544 vs 18044). In PassMark, the Intel chip wins data compression by 15.2% (695234 vs 603371), data encryption by 9.8% (40091 vs 36499), floating point math by a massive 39.2% (134222 vs 96446), and integer math by 12.2% (182876 vs 162993). It also takes the PassMark multithread test (52392 vs 50547, a 3.7% edge) and random string sorting (74733 vs 71642, 4.3% ahead). The single-thread PassMark test also goes to Intel (4472 vs 4119, 8.6% higher).

The AMD EPYC 4484PX wins where single-core performance and certain specialized instructions matter most. Its Cinebench R23 single-core score is 6065 versus 2160 for the Intel chip — a staggering 64.4% lead that also shows up in Cinebench R15 single-core (611 vs 313.5, a 48.7% advantage). The AMD part takes Cinebench R23 multicore outright with 42964 vs 33440.5, a 22.2% margin, despite losing the other two Cinebench multicore tests. In PassMark, the EPYC wins extended instructions (43315 vs 40632, 6.2% ahead), find prime numbers (425 vs 212, 50.1% higher), and physics (4938 vs 2964, a 40% lead). These wins point to a processor that excels in single-threaded responsiveness and specific computational patterns, rather than broad multi-core throughput.

Architecture Differences

The two processors come from opposite design philosophies. The Intel Core i7-14700K is built on Raptor Lake-R, a 10 nm process at Intel’s own foundry, with 20 cores and 28 threads. The AMD EPYC 4484PX uses Zen 4 architecture on a 5 nm TSMC process, with 12 cores and 24 threads. The Intel chip has a larger die at 257 mm², while the AMD part uses two chiplets at 2x 71 mm², totaling 17,840 million transistors. Cache configurations diverge sharply: Intel offers 80 KB L1 and 2 MB L2 per core with 33 MB shared L3, while AMD provides 64 KB L1 and 1 MB L2 per core but a much larger 128 MB shared L3, plus a dedicated 1x 64MB 3D V-Cache slice. That extra L3 capacity is the likely driver behind the EPYC’s single-thread dominance.

Base clocks favor AMD at 4.40 GHz versus Intel’s 3.40 GHz, though both boost to 5.60 GHz. The Intel part supports both DDR4 and DDR5 memory, while the AMD chip is DDR5-only, and the EPYC lists a memory bandwidth of 83.2 GB/s that Intel does not specify. PCIe lanes also differ: the Intel i7-14700K provides Gen 5 with 16 lanes, while the EPYC 4484PX offers Gen 5 with 28 lanes. Both have integrated graphics, with Intel using UHD Graphics 770 and AMD using Radeon Graphics, and both support ECC memory. The Intel chip is socketed for LGA 1700, the AMD for AM5, and the Intel part has an unlocked multiplier while the EPYC does not.

Head-to-Head Benchmarks

The most dramatic result in the entire dataset is the Cinebench R23 single-core test, where the AMD EPYC 4484PX scores 6065 against the Intel Core i7-14700K’s 2160. That 64.4% deficit for Intel is the largest single delta in either direction, and it is echoed by a 48.7% loss in Cinebench R15 single-core (611 vs 313.5). These are not marginal differences; the EPYC is in a different performance tier for single-threaded execution, likely due to its higher 4.40 GHz base clock and the 128 MB L3 cache with the 3D V-Cache slice.

The Intel chip’s biggest win is floating point math, where it scores 134222 versus 96446, a 39.2% advantage. That is followed by a 16.3% win in Cinebench R15 multicore (5035 vs 4330) and a 15.2% win in data compression (695234 vs 603371). The Intel part also takes Cinebench R20 multicore by a slim 2.8% (18544 vs 18044) and Cinebench R20 single-core by 2.7% (2617 vs 2547). Interestingly, the AMD chip wins Cinebench R23 multicore by 22.2% (42964 vs 33440.5), which contradicts the R15 and R20 multicore results — the newer R23 workload appears to favor the EPYC’s cache and architecture more heavily.

In PassMark, the AMD EPYC 4484PX wins find prime numbers by 50.1% (425 vs 212) and physics by 40% (4938 vs 2964), but loses extended instructions by only 6.2% (43315 vs 40632). The Intel chip takes integer math by 12.2% (182876 vs 162993), multithread by 3.7% (52392 vs 50547), and random string sorting by 4.3% (74733 vs 71642). Single-thread PassMark goes to Intel at 4472 versus 4119, an 8.6% lead that runs counter to the Cinebench single-core results — indicating the two benchmarks measure different aspects of single-thread performance.

The Verdict

The data points to a clear split: the Intel Core i7-14700K is the better choice for anyone running a broad mix of multi-threaded and integer-heavy workloads. Its wins in Cinebench R15 and R20 multicore, floating point math, data compression, and integer math make it the more versatile processor for general computing, content creation, and number-crunching tasks. The 39.2% lead in floating point math is particularly decisive, and its 8.6% edge in single-thread PassMark shows it is not weak in that area either.

The AMD EPYC 4484PX, despite losing the overall benchmark count, should be the pick for workloads that are heavily single-threaded or dependent on large cache and specialized instructions. Its 64.4% lead in Cinebench R23 single-core and 50.1% lead in find prime numbers are not anomalies — they reflect a design optimized for latency-sensitive and cache-heavy tasks. The 22.2% win in Cinebench R23 multicore also suggests that newer, more cache-demanding multi-threaded workloads will favor the EPYC. With 28 PCIe Gen 5 lanes versus Intel’s 16, the AMD part is also better positioned for server and workstation I/O demands.

Neither processor is objectively superior. The Intel Core i7-14700K offers 20 cores and a 125W TDP, while the AMD EPYC 4484PX offers 12 cores at 120W with a much larger cache. The Intel chip has an unlocked multiplier and supports DDR4 and DDR5; the AMD chip is locked and DDR5-only. For desktop and general multi-threaded use, the Intel Core i7-14700K’s 11 wins and higher average benchmark score of 69355 (versus 67822) make it the data-backed recommendation. For single-threaded performance and server-style workloads, the AMD EPYC 4484PX’s dominant Cinebench single-core scores and 128 MB L3 cache make it the clear choice.
