AMD EPYC 7773X vs Intel Core i3-14100F Comparison

Head-to-Head Benchmarks

The recorded data presents an extraordinarily lopsided head-to-head comparison. The AMD EPYC 7773X wins 7 of the 8 shared benchmark tests, with the Intel Core i3-14100F taking a single victory. The margins in the Cinebench suite are staggering, with the EPYC 7773X leading by roughly 493.4% to 493.9% across all six tests. In Cinebench R15 multicore, the EPYC 7773X scores 7825 against 1318, a delta of 493.7%. The R20 multicore test shows 32608 versus 5495, a delta of 493.4%. R23 multicore follows the same pattern at 77639 against 13084, a 493.4% delta. Single-core results in Cinebench are equally dominant for the AMD part: R15 singlecore shows 1104 versus 186, a 493.5% delta; R20 singlecore shows 4603 versus 775, a 493.5% delta; and R23 singlecore shows 10960 versus 1847, a 493.4% delta. The EPYC 7773X also wins Geekbench multicore with 15554 versus 7598, a 104.7% advantage. The sole Intel victory comes in Geekbench singlecore, where the i3-14100F scores 2105 against 1536, a -27% delta for the AMD chip. That single result aside, the EPYC 7773X dominates every multithreaded and most single-threaded workloads in the shared benchmark set.

Where Each One Wins

The benchmark data indicates a clear division of labor between these two processors. The AMD EPYC 7773X is the overwhelming winner in all multithreaded scenarios. Its 64 cores and 128 threads give it a decisive edge in heavily parallel workloads, as reflected in the Cinebench multicore tests and Geekbench multicore. The R23 multicore score of 77639 is roughly 5.9 times higher than the i3-14100F's 13084, which is exactly the kind of advantage one expects from a server-class part. Similarly, the R20 multicore result of 32608 dwarfs the Intel part's 5495, and the R15 multicore score of 7825 is nearly 6 times the i3's 1318. Geekbench multicore shows a 104.7% lead for the EPYC 7773X, meaning it more than doubles the Intel processor's score of 7598.

The Intel Core i3-14100F wins in one specific area: Geekbench singlecore. Its score of 2105 is 27% higher than the EPYC 7773X's 1536. This is notable because the i3-14100F achieves it with a 4.70 GHz boost clock versus the EPYC's 3.50 GHz, and with only 4 cores and 8 threads. The i3-14100F also has additional benchmark data in the database, including PassMark tests, but those have no direct comparison with the EPYC 7773X. In the shared tests, the i3-14100F's single-core advantage is its only win. For workloads that rely on raw per-thread performance, such as lightly threaded applications, the Intel part holds the edge. For anything that scales across cores, cores, threads, the EPYC 7773X is the clear choice. The i3-14100F's 4 cores and 8 threads simply cannot match the parallel throughput of 64 cores and 128 threads in the EPYC part in any multithreaded test.

Architecture Differences

The architecture differences between these two processors are fundamental and fundamental to understanding the benchmark results. The AMD EPYC 7773X is built on Zen 3 architecture, specifically the Milan-X codename, and is part of the EPYC 7003 series. It is fabricated on a 7 nm process node by TSMC. The Intel Core i3-14100F uses Raptor Lake architecture with the Rapt Lake-R codename, part of Core 14th Gen, and is manufactured on a 10 nm process node by Intel Foundry. The EPYC 7773X has 64 cores and 128 threads, while the i3-14100F has 4 cores and 8 threads. The 3D V-Cache technology, while not explicitly listed, is implied by the Milan-X codename, a server-specific variant of Milan with stacked L3 cache. The EPYC 7773X has 768 MB of shared L3 cache, a massive cache pool, versus the i3-14100F's 12 MB shared L3. L1 cache per core is 64 KB for the EPYC versus 80 KB per core for the i3. L2 cache per core is 512 KB for the EPYC versus 1.25 MB per core on the Intel part. Process node, cores, threads, cache capacities, and codenames all differ, and these differences in cache and core count explain the massive multithreaded gap in benchmark scores.
