AMD Ryzen 9 7940HX vs Intel Core i9-14901E Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive split between these two processors, with the AMD Ryzen 9 7940HX winning 9 of the 13 shared benchmark comparisons, while the Intel Core i9-14901E takes 4 wins. The most dramatic margin appears in passmark_extended_instructions, where AMD leads by 195.8%, scoring 51029 against Intel's 17249. That result indicates a massive advantage in workloads that leverage advanced instruction sets, likely reflecting the Zen 4 architecture's execution capabilities.

Data compression heavily favors AMD as well. The Ryzen 9 7940HX scores 693741 in passmark_data_compression versus 288777 for the Intel chip, a 140.2% delta. Encryption follows a similar pattern: 41974 versus 18571, a 126% lead. These are substantial gaps, and they suggest that data-intensive tasks, such as archiving, database operations, or secure communication processing, will run considerably faster on the AMD part.

Integer math also skews strongly toward AMD, with a score of 202883 compared to 112736, an 80% advantage. Floating point math shows a 49.7% lead (121383 versus 81089). Random string sorting delivers a 108.9% difference (81775 versus 39138). The pattern is consistent: AMD dominates throughput-oriented workloads that scale with core count and memory bandwidth.

The multi-threaded PassMark score reinforces this, with AMD at 53204 versus Intel's 30298, a 75.6% margin. The Cinebench R23 multi-core result shows AMD ahead by 14.2%, scoring 29400 versus 25753. Interestingly, the multi-core advantage in Cinebench is smaller than in PassMark, which suggests that the Ryzen's extra cores and threads provide a larger benefit in certain synthetic workloads than in the rendering engine.

Intel's wins are concentrated in single-threaded and lightly threaded tests. The Cinebench R23 single-core score shows Intel at 3635 versus AMD's 1807, a 50.3% lead. That is an enormous difference, nearly double the AMD score. PassMark single-thread confirms the trend, with Intel ahead by 9.5% (4354 versus 3942). The physics test also goes to Intel, scoring 3041 against AMD's 2297, a 24.5% lead. Physics simulations often rely on high per-core performance and lower latency, so this result aligns with Intel's clock speed advantage.

The fundamental question is whether the 16-core AMD part's massive throughput leads can overcome Intel's single-core dominance. The data indicates that for heavily parallel workloads, AMD is the clear winner, often by double-digit or triple-digit percentages. For latency-sensitive or lightly threaded applications, Intel holds the advantage, particularly in the Cinebench single-core test where the margin is extreme.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen 9 7940HX uses the Zen 4 architecture, codenamed Dragon Range, built on a 5 nm process at TSMC. Intel's Core i9-14901E uses Raptor Lake, specifically the Raptor Lake-R variant, on Intel's 10 nm process. The process node difference is significant: 5 nm versus 10 nm, which typically implies higher transistor density and better power efficiency for the AMD part, though the Intel chip compensates with a higher boost clock.

Core counts differ substantially. AMD offers 16 cores and 32 threads, while Intel provides 8 cores and 16 threads. That is a 2x difference in both metrics. The Ryzen 9 7940HX also has a larger L3 cache: 64 MB total, compared to Intel's 36 MB shared L3. Per-core L2 cache favors Intel, however, with 2 MB per core versus AMD's 1 MB per core. L1 cache also differs: Intel has 80 KB per core, AMD has 64 KB per core.

The AMD chip uses a dual-die design, with a die size of 2x 71 mm² and 13,140 million transistors. Intel uses a single monolithic die of 257 mm². The transistor count for Intel is not recorded in the database, so a direct comparison there is unavailable. AMD's chiplet approach with two dies likely facilitates the higher core count, while Intel's monolithic design keeps all 8 cores on one piece of silicon.

Memory support is another differentiator. AMD supports DDR5 only, with dual-channel memory and a recorded bandwidth of 83.2 GB/s. Intel supports both DDR4 and DDR5, also dual-channel, but its memory bandwidth is not recorded. ECC memory support is present on Intel but absent on AMD. This matters for workstation or server-adjacent use cases where data integrity is critical.

PCIe lanes also differ. AMD provides Gen 5 with 28 lanes (CPU only), while Intel provides Gen 5 with 16 lanes (CPU only). The AMD part has nearly twice the lane count, which could support more expansion devices or faster storage configurations. Integrated graphics differ as well: AMD uses the Radeon 610M, while Intel uses UHD Graphics 770. Both are integrated solutions, but their performance characteristics are not compared in the recorded data.

The sockets are incompatible: AMD uses Socket FL1, Intel uses Socket 1700. The AMD chip is unlocked for overclocking, while Intel's multiplier is locked. The AMD part is classified as mobile, while Intel's is desktop. Release dates differ by roughly five months: AMD launched on January 16, 2024, and Intel on June 30, 2024.

Where Each One Wins

The AMD Ryzen 9 7940HX wins in every multi-threaded and data-throughput category measured. PassMark multithread, integer math, floating point math, data compression, data encryption, extended instructions, prime number finding, and random string sorting all favor AMD by margins ranging from 44.4% to 195.8%. The practical implication is that AMD is the stronger choice for rendering, video encoding, scientific computation, database processing, compression workloads, and any task that can use more than 16 threads.

The Cinebench R23 multi-core result, while still an AMD win, is closer at 14.2%. This suggests that Cinebench's rendering workload does not scale perfectly with the Ryzen's 32 threads, or that Intel's higher per-core clock speed partially compensates. Still, the AMD part delivers a higher absolute score.

The Intel Core i9-14901E wins in single-threaded performance, as measured by Cinebench R23 single-core and PassMark single-thread. The 50.3% lead in Cinebench is striking and indicates that Intel's 5.60 GHz boost clock, combined with the Raptor Lake architecture, delivers superior per-core execution. The physics test also favors Intel by 24.5%, which suggests that physics simulations in benchmarks, often dependent on single-thread performance and cache latency, run better on the Intel chip.

For users running lightly threaded applications, such as older games, spreadsheet calculations, or scripting workloads that cannot parallelize, Intel offers measurably better performance. The PassMark single-thread margin of 9.5% is more modest than the Cinebench gap, but still favors Intel.

The split is clear: AMD for parallel throughput, Intel for serial performance. A workload that uses all cores will see AMD ahead by 14% to 196%. A workload that uses one or two cores will see Intel ahead by 9.5% to 50.3%.

Specification Differences

The Verdict

The benchmark data presents a clear trade-off. The AMD Ryzen 9 7940HX is the superior processor for any workload that can utilize multiple cores, with wins in 9 of 13 comparisons and margins exceeding 100% in several PassMark subtests. The 16-core, 32-thread configuration, combined with 64 MB of L3 cache and 83.2 GB/s of memory bandwidth, delivers exceptional throughput for rendering, compression, encryption, and mathematical computation. The percentile ranking of 94 versus Intel's 86 reflects this overall advantage.

The Intel Core i9-14901E is the better choice for single-threaded performance. Its 5.60 GHz boost clock and 50.3% lead in Cinebench R23 single-core make it attractive for applications that depend on one or two fast cores, such as legacy software, certain simulation workloads (the physics test shows a 24.5% Intel lead), or tasks where latency matters more than raw throughput. The ECC memory support and dual DDR4/DDR5 compatibility also make it suitable for systems that require validated memory or want to reuse older DDR4 modules.

Data-driven selection depends on the workload profile. For multi-threaded production tasks, the AMD processor's 14.2% Cinebench multi-core lead and 75.6% PassMark multithread lead are decisive. For single-threaded responsiveness, the Intel processor's 9.5% to 50.3% leads are equally clear. The database shows no single winner across all categories; instead, it reveals two specialists with opposing strengths.
