Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Core i7-14700HX is a 20-core, 28-thread mobile part built on Intel's Raptor Lake architecture, using the Raptor Lake-HX refresh generation. It runs on the Intel BGA 1964 socket and is fabbed on Intel's 10 nm process node with a 257 mm² die size. The AMD EPYC 4344P is an 8-core, 16-thread server/workstation chip based on Zen 4 (Raphael), using AMD's Socket AM5. It is manufactured by TSMC on a 5 nm process with a much smaller 71 mm² die and 6,570 million transistors.

Cache configurations differ notably. The Intel part allocates 80 KB of L1 cache per core, 2 MB of L2 per core, and 33 MB of shared L3. The AMD chip uses 64 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3. While the Intel chip has slightly more L3, the AMD chip's smaller per-core cache footprint is offset by its higher base clock of 3.80 GHz versus Intel's 2.10 GHz. Boost clocks are closer: 5.50 GHz for Intel and 5.30 GHz for AMD.

Memory support diverges as well. The Intel part supports both DDR4 and DDR5 on a dual-channel bus, while the AMD chip supports only DDR5 on dual-channel with a specified memory bandwidth of 83.2 GB/s. Both support ECC memory. PCIe connectivity also differs: the Intel part offers Gen 5 with 16 CPU lanes, while the AMD chip offers Gen 5 with 28 CPU lanes. Integrated graphics are present on both — Intel's UHD Graphics 770 versus AMD's Radeon Graphics.

The Intel chip has an unlocked multiplier and a 55 W TDP, whereas the AMD chip is locked and rated at 65 W TDP. The Intel part launched earlier (2024-01-07) and the AMD part later (2024-05-20). The AMD EPYC 4344P has a launch MSRP of $329. The Intel part carries part number SRMXG, while the AMD chip is 100-000001479.

The Verdict

The data points to a processor that wins on raw thread throughput and one that wins on efficiency per core. The Intel Core i7-14700HX takes the majority of benchmarks — 12 wins versus 5 — and its average benchmark score of 45,953 edges out the EPYC's 45,122. Its dominance in floating point math (48.2% ahead), integer math (24.1%), and Cinebench R15 multi-core (32.1%) makes it the stronger choice for compute-heavy multi-threaded workloads that scale across many cores.

The AMD EPYC 4344P, despite having only 8 cores and 16 threads, demonstrates superior per-core performance in certain workloads. Its 48% lead in Cinebench R23 single-core and 27.3% lead in Cinebench R15 single-core indicate that applications sensitive to single-thread performance will favor AMD. The EPYC also wins Cinebench R23 multi-core by 14.1%, suggesting that some modern multi-threaded rendering workloads respond better to its architecture despite fewer cores.

The trade-off is clear: the Intel part offers 20 cores and 28 threads versus the EPYC's 8 cores and 16 threads, yet the EPYC still manages to win a significant multi-core test. This suggests the EPYC's Zen 4 architecture extracts more work per thread in certain scenarios. For users prioritizing maximum multi-threaded throughput across a wide range of workloads, the i7-14700HX's 12 benchmark wins make it the safer choice. For users running applications that are heavily single-thread bound or that specifically favor the EPYC's architecture in Cinebench R23, the AMD part holds distinct advantages.

Specification Differences

The two processors differ on nearly every major specification. The Intel Core i7-14700HX offers 20 cores and 28 threads, while the AMD EPYC 4344P offers 8 cores and 16 threads. Base clocks are 2.10 GHz for Intel versus 3.80 GHz for AMD; boost clocks are 5.50 GHz versus 5.30 GHz. TDP is 55 W for Intel and 65 W for AMD. The Intel chip uses the Intel BGA 1964 socket, while AMD uses Socket AM5. Process nodes are 10 nm (Intel) and 5 nm (TSMC for AMD).

Cache hierarchies differ: Intel has 80 KB L1 per core, 2 MB L2 per core, and 33 MB shared L3; AMD has 64 KB L1 per core, 1 MB L2 per core, and 32 MB shared L3. Memory support shows Intel accepting both DDR4 and DDR5, while AMD is DDR5-only; both use dual-channel buses, but AMD specifies 83.2 GB/s bandwidth. PCIe lanes differ — 16 for Intel versus 28 for AMD, both Gen 5. Integrated graphics are UHD Graphics 770 on Intel and Radeon Graphics on AMD. The Intel multiplier is unlocked; AMD's is locked. The AMD chip has a launch MSRP of $329. Release dates are 2024-01-07 for Intel and 2024-05-20 for AMD. The Intel die is 257 mm²; the AMD die is 71 mm² with 6,570 million transistors.

Where Each One Wins

The Intel Core i7-14700HX is the clear winner in math-intensive workloads. Its 48.2% advantage in floating point math and 24.1% lead in integer math make it the pick for scientific computing, financial modeling, and any task relying on heavy arithmetic. It also wins data compression by 8.9% and data encryption by 6.6%, making it suitable for database workloads, file archiving, and security applications. The 32.1% lead in Cinebench R15 multi-core and 8.6% wins in both R20 multi-core and single-core suggest strong all-around rendering performance, while the 13.3% physics win and 9.7% multi-thread win reinforce its position for simulation and general parallel tasks.

The AMD EPYC 4344P wins where single-core Cinebench performance matters most. Its 48% lead in R23 single-core and 27.3% lead in R15 single-core point to applications that rely on one dominant thread — legacy software, certain game engines, or lightly threaded productivity tools. The 14.1% win in Cinebench R23 multi-core also makes it competitive for modern rendering pipelines that are optimized for Zen 4's instruction handling. Its 13.1% lead in extended instructions suggests better performance in AVX-heavy or SIMD-optimized code. The 0.9% edge in random string sorting is marginal but indicates a slight advantage in text processing or data serialization tasks.

For anyone choosing between them, the decision hinges on workload type. The i7-14700HX's 12 wins and higher average score make it the more versatile processor. The EPYC 4344P's specific wins — particularly the huge single-core Cinebench margins — make it a targeted choice for users who know their primary applications favor its architecture.
