AMD EPYC 9184X vs Intel Core i7-14700K Comparison

The Intel Core i7-14700K and AMD EPYC 9184X represent two distinct poles of the processor market: a high-end desktop part with a hybrid core layout versus a server-focused chip with massive cache. The benchmark data reveals a complex picture where neither processor dominates outright, with the Intel chip winning 10 of 17 head-to-head tests and the AMD EPYC taking 7. The overall average benchmark scores are remarkably close, with the Intel part posting 69,355 and the AMD part at 68,202, placing both in the 94th percentile of all CPUs. This parity in overall scores, however, masks significant and consistent performance swings across different workload types, driven by fundamental architectural differences.

Head-to-Head Benchmarks

The Intel Core i7-14700K establishes its strongest leads in single-threaded and multi-threaded desktop-centric tasks. In the PassMark single-thread test, the Intel chip scores 4,472 against the EPYC's 2,822, a decisive 58.5% advantage. This pattern repeats in Cinebench R15 single-core, where Intel's score of 313.5 is 45.6% lower than AMD's 576, marking the EPYC's largest win. However, the Intel chip's performance is not limited to single-threaded work; it also wins the Cinebench R20 multicore test with 18,544 points, a 9% margin over the EPYC's 17,016. The Intel part also demonstrates superiority in integer-heavy workloads, scoring 182,876 in PassMark integer math versus 157,483 for the EPYC, a 16.1% lead, and in floating-point math, where it posts 134,222 against 95,476, a commanding 40.6% advantage.

The AMD EPYC 9184X, meanwhile, shows its strength in cache-sensitive and multi-threaded rendering workloads. Its most impressive result comes in Cinebench R23 multicore, where it scores 40,515 against Intel's 33,440.5, a 17.5% lead. The single-core Cinebench R20 test is another win for AMD, with a score of 2,401 versus Intel's 2,617, a 9% deficit for the EPYC. The EPYC's dominance is most pronounced in the PassMark physics test, where it achieves 6,674 points compared to Intel's 2,964, a substantial 55.6% margin. It also leads in prime number finding (465 vs. 212, a 54.4% difference) and extended instructions (43,562 vs. 40,632, a 6.7% edge). The EPYC also wins the Cinebench R15 single-core and PassMark random string sorting tests, with the latter being a narrow 6.5% victory.

The data shows that the Intel Core i7-14700K is the clear winner in memory compression (695,234 vs. 614,873, a 13.1% lead) and encryption (40,091 vs. 37,376, a 7.3% margin). In the Cinebench R15 multicore test, Intel wins with 5,035 points against 4,083, a 23.3% advantage. The PassMark multithread score also favors Intel at 52,392 versus 47,665, a 9.9% difference. These results indicate that while the EPYC can pull ahead in specific server-style workloads, the Intel desktop part is generally faster in the common consumer and professional benchmark suites, except for the notable exception of Cinebench R23 multicore where the EPYC's large cache provides a significant boost.

The Verdict

Based strictly on the benchmark data, the choice between these two processors depends entirely on the workload profile. The Intel Core i7-14700K is the superior choice for general desktop, gaming, and typical productivity tasks. Its 58.5% lead in PassMark single-thread and 40.6% lead in floating-point math make it the better option for applications that rely on strong per-core performance and fast math operations. The data also suggests it is the better pick for data compression and encryption tasks, where it holds 13.1% and 7.3% leads respectively. Users running Cinebench R15 or R20 multi-threaded workloads will also find the Intel chip faster, with margins of 23.3% and 9%.

The AMD EPYC 9184X is the clear winner for server and scientific computing tasks that are heavily cache-dependent. Its 17.5% lead in Cinebench R23 multicore and 55.6% lead in the PassMark physics test indicate a significant advantage in rendering and physics simulation. The 54.4% margin in prime number finding suggests it is better suited for integer-heavy algorithmic workloads. For single-core Cinebench R15, the EPYC is 45.6% faster, which is a surprising result given its lower boost clock. The EPYC also wins in extended instructions and random string sorting, making it a target for specialized enterprise software. The data shows that the EPYC is not a general-purpose winner, but it is the stronger performer in specific high-value server workloads. The Intel chip's 10 wins out of 17 tests, combined with its higher average score, makes it the more versatile processor for a broad range of applications.

Architecture Differences

The Intel Core i7-14700K is built on a 10 nm process at Intel, using the Raptor Lake architecture with a Raptor Lake-R codename. It features 20 cores and 28 threads, which indicates a hybrid design combining performance and efficiency cores. The AMD EPYC 9184X uses a 5 nm process at TSMC, with the Zen 4 architecture and Genoa-X codename. It has 16 cores and 32 threads, all being full performance cores. The die sizes differ significantly, with the Intel part at 257 mm² and the AMD part using 8x 72 mm² dies, totaling 576 mm². The AMD chip has a vastly larger transistor count at 90,160 million, while the Intel part's transistor count is not specified.

The cache configuration is the most striking architectural difference. The Intel chip has 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The AMD EPYC has 64 KB of L1 per core, 1 MB of L2 per core, and a massive 768 MB of shared L3 cache. This 23-fold difference in L3 capacity is the primary driver behind the EPYC's strong performance in cache-sensitive workloads like Cinebench R23 multicore and physics simulations. The Intel chip relies on a higher boost clock of 5.60 GHz versus the EPYC's 4.20 GHz to achieve its single-thread and math performance advantages. The EPYC also supports a much wider memory bus with twelve channels versus Intel's dual-channel, and offers a memory bandwidth of 460.8 GB/s, which is not specified for the Intel part. Both processors support ECC memory, but the Intel part includes integrated UHD Graphics 770, while the EPYC has no integrated graphics.

Specification Differences

The key specification differences between the two processors are stark. The Intel Core i7-14700K has 20 cores and 28 threads, while the AMD EPYC 9184X has 16 cores and 32 threads. The base clock is higher on the EPYC at 3.55 GHz compared to 3.40 GHz on Intel, but the boost clock is much higher on Intel at 5.60 GHz versus 4.20 GHz. The TDP is dramatically different, with the Intel part rated at 125 W and the AMD part at 320 W. The sockets are incompatible, with Intel using Socket 1700 and AMD using Socket SP5. The process nodes differ, with Intel at 10 nm and AMD at 5 nm, and the foundries are also different (Intel vs. TSMC). The memory support is a key differentiator: the Intel chip supports both DDR4 and DDR5, while the EPYC supports only DDR5. The memory bus is dual-channel on Intel and twelve-channel on AMD, and the EPYC has a specified memory bandwidth of 460.8 GB/s. PCIe support is another major difference, with Intel offering Gen 5 with 16 CPU lanes and the EPYC offering Gen 5 with 128 CPU lanes. The Intel part has an unlocked multiplier, while the EPYC is locked. The market segments are also distinct: Intel is for Desktop, and AMD is for Server/Workstation. The release dates are different, with Intel launching on 2023-10-16 and AMD on 2023-06-12.
