Where Each One Wins

The Intel Core i7-13700K is the clear winner for heavily parallel workloads. It dominates the Cinebench R15 and R20 multi-core tests, taking a 28.4% lead in R15 and a 17.5% lead in R20. In PassMark, it wins every single multi-threaded test: data compression by 29.2%, data encryption by 29.9%, floating point math by 35.4%, integer math by 19.9%, multithread by 21.3%, random string sorting by 26.2%, and find prime numbers by 12.6%. It also wins the extended instructions test by 13.5% and physics by 4.9%. If the workload scales with cores, the i7-13700K is the pick.

The AMD EPYC 4345P wins where single-core efficiency and raw per-thread speed matter most. Its Cinebench R23 single-core score of 4520 crushes the Intel part's 2116, a 113.6% advantage. In Cinebench R15 single-core, it leads 455 to 303, a 50.2% margin. It also edges out the Intel part in PassMark single-thread, 4408 to 4333, a 1.7% win. The EPYC also wins the Cinebench R23 multi-core test, 32020 to 30745, a 4.1% advantage, which is notable given its 8-core versus 16-core deficit.

Architecture Differences

The AMD EPYC 4345P uses the Zen 5 architecture, codenamed Grado, built on a 4 nm process at TSMC. It packs 8,315 million transistors into a 70.6 mm² die. The Intel Core i7-13700K uses the Raptor Lake architecture, Raptor Lake-S, on Intel's 10 nm process with a 257 mm² die size. The process node difference is significant: the AMD part's 4 nm process gives it a major density and efficiency advantage, which shows in its 65 watt TDP versus the Intel part's 125 watt TDP.

Cache layouts differ as well. Both have 80 KB of L1 per core. The AMD part has 1 MB of L2 per core, while the Intel part has 2 MB per core. For L3, the AMD EPYC has 32 MB shared, and the Intel part has 30 MB shared. Neither has 3D V-Cache.

Memory support diverges. The AMD EPYC 4345P supports only DDR5 on a dual-channel bus with 89.6 GB/s of bandwidth. The Intel Core i7-13700K supports both DDR4 and DDR5 on a dual-channel bus, though its memory bandwidth figure is not recorded in the database. Both support ECC memory.

PCIe connectivity differs. The AMD part offers Gen 5 with 24 lanes (CPU only), while the Intel part offers Gen 5 with 20 lanes (CPU only). The AMD part includes Radeon Graphics as integrated graphics, while the Intel part has UHD Graphics 770. The AMD EPYC is aimed at the server/workstation segment, while the Intel i7-13700K is a desktop part. The AMD part does not have an unlocked multiplier, while the Intel part does. The AMD EPYC also has a higher boost clock of 5.50 GHz versus 5.40 GHz, and a higher base clock of 3.80 GHz versus 3.40 GHz.

Head-to-Head Benchmarks

The biggest Intel win comes in Cinebench R15 multi-core, where it scores 4507.5 against the AMD part's 3227, a 28.4% margin. That pattern repeats across most multi-threaded PassMark tests. In floating point math, Intel takes 114867 versus 74255, a 35.4% lead. Data compression goes 595292 to 421490, a 29.2% gap. Data encryption goes 33249 to 23313, a 29.9% gap. Random string sorting goes 62670 to 46238, a 26.2% gap. Multithread goes 45887 to 36123, a 21.3% gap. Integer math goes 154446 to 123774, a 19.9% gap. Extended instructions go 36625 to 31663, a 13.5% gap. Even the smaller wins matter: find prime numbers goes 191 to 167, a 12.6% gap, and physics goes 2716 to 2583, a 4.9% gap.

The AMD EPYC 4345P's wins are fewer but more extreme. The single-core Cinebench R23 result stands out: 4520 versus 2116, a 113.6% advantage. That is not a small margin; it is more than double the Intel score. Cinebench R15 single-core also goes AMD's way, 455 versus 303, a 50.2% lead. In the Cinebench R23 multi-core test, the AMD part wins 32020 to 30745, a 4.1% edge, which is surprising given the core count difference. PassMark single-thread goes to AMD by a narrow 1.7% margin, 4408 to 4333.

The Cinebench R20 results split differently. Intel wins multi-core, 16292 to 13448, a 17.5% margin. Intel also wins single-core there, 2299 to 1898, a 17.4% margin, which contradicts the R23 single-core result. The database records these differences without explanation, but the pattern suggests that the AMD part's advantage shows most clearly in the newer R23 workload.

The Verdict

Choose the Intel Core i7-13700K if your work scales across many cores. It wins 12 of 17 head-to-head benchmarks, and its wins are broad and consistent across compression, encryption, math, sorting, and integer workloads. The 16 cores and 24 threads give it a structural advantage that shows in nearly every multi-threaded test. It also supports DDR4 and DDR5, giving memory flexibility that the AMD part lacks. The unlocked multiplier on the Intel part is another point in its favor for those who tune their systems.

Choose the AMD EPYC 4345P if single-threaded performance is the priority, or if power efficiency matters more than raw core count. Its Cinebench R23 single-core result is over double the Intel part's score, a 113.6% lead. Its 65 watt TDP versus 125 watts means it draws far less power for a similar average benchmark score. The EPYC also holds a higher average benchmark score overall, 48470 versus 46881, and a higher percentile ranking. Its 5 head-to-head wins include the most important single-core tests and one multi-core test, Cinebench R23, where it beats the Intel part despite having half the cores.

For a server or workstation where single-thread responsiveness and low power draw matter, the EPYC 4345P is the better fit. For a desktop where you want maximum multi-threaded throughput and don't mind the higher power draw, the Core i7-13700K is the stronger choice. The data does not favor one across the board; it depends entirely on which workload you feed them.
