Architecture Differences

The Intel Core i5-14500HX is built on the Raptor Lake-HX architecture, a 10 nm process from Intel's own foundry, with a die size of 257 mm². The AMD Ryzen 7 3700X uses the Zen 2 architecture, codenamed Matisse, manufactured on a 7 nm process by TSMC, with a significantly smaller die size of 74 mm² and 3,800 million transistors. These process and foundry differences explain much of the performance gap: the Intel design prioritizes higher clock speeds and a larger core count, while the AMD part focuses on efficiency and a smaller physical footprint.

The Intel Core i5-14500HX packs 14 cores and 20 threads, a hybrid configuration that allows more simultaneous work than the AMD's 8 cores and 16 threads. Cache hierarchies also differ substantially. The Intel part provides 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3. The AMD Ryzen 7 3700X offers 64 KB of L1 per core, 512 KB of L2 per core, and a larger 32 MB of L3. The larger L3 on the AMD part does not compensate for the core count and clock speed advantages of the Intel chip in the recorded benchmarks.

Memory support is another dividing line. The Intel Core i5-14500HX supports both DDR4 and DDR5, while the AMD Ryzen 7 3700X is limited to DDR4. The AMD part has a recorded memory bandwidth of 51.2 GB/s, whereas the Intel part has no bandwidth figure in the database. Both use dual-channel memory buses. PCIe support also differs: the Intel provides Gen 5 with 16 lanes (CPU only), while the AMD provides Gen 4 with 24 lanes (CPU only). Integrated graphics are present on the Intel (UHD Graphics 770) but absent on the AMD.

The Intel is a mobile part, released on January 7, 2024, while the AMD is a desktop part, released on July 6, 2019. Both are unlocked for multiplier adjustment, and both are currently marked as active in production. The Intel has no launch MSRP recorded, whereas the AMD has a launch MSRP of $329.

Head-to-Head Benchmarks

The recorded data shows a clean sweep: the Intel Core i5-14500HX wins all 15 shared benchmarks, with zero wins for the AMD Ryzen 7 3700X. The margins vary widely, from modest single-digit advantages to near-doubling in specific workloads.

The largest gap appears in PassMark floating-point math, where the Intel scores 69,442 against the AMD's 39,005, a 78% advantage. This indicates a substantial edge in workloads that rely on heavy numerical computation. Similarly, PassMark physics shows a 61.8% lead for the Intel (1,911 versus 1,181), suggesting better performance in simulation and physics-based tasks. Integer math follows with a 44% gap (95,584 versus 66,399), reinforcing the Intel's dominance in arithmetic-heavy operations.

Single-core performance is also decisively in Intel's favor. Cinebench R15 single-core shows a 68.6% lead (344 versus 204), while Geekbench single-core shows a 33.6% lead (2,129 versus 1,593). PassMark single-thread tests confirm the pattern with a 36.6% gap (3,629 versus 2,656). These numbers indicate that the Intel part not only has more cores but also executes individual threads more efficiently, a critical factor for lightly threaded applications.

Multi-core benchmarks follow the same trend. Cinebench R15 multi-core gives the Intel a 16.7% lead (2,442 versus 2,092), and Geekbench multi-core shows a 14.3% lead (10,171 versus 8,899). PassMark multithread is 26.9% in Intel's favor (28,508 versus 22,458). The consistency across different benchmark suites strengthens the conclusion that the Intel part is faster in both single-threaded and multi-threaded scenarios.

Some workloads show smaller gaps. PassMark data encryption is only 3.2% apart (19,502 versus 18,900), and extended instructions are 4% apart (20,019 versus 19,241). Data compression shows a 12.6% gap (333,851 versus 296,379), and random string sorting is 12.7% apart (36,219 versus 32,131). Prime number finding shows a 31.3% gap (130 versus 99). Even in the closest tests, the Intel part remains ahead.

The Verdict

The data points to a clear choice for most workloads: the Intel Core i5-14500HX outperforms the AMD Ryzen 7 3700X in every recorded benchmark. With 15 wins out of 15, the Intel part is faster in single-core, multi-core, math, encryption, compression, and sorting tasks. The margins range from 3.2% in data encryption to 78% in floating-point math, with most gaps falling between 12% and 45%.

The Intel's advantages come from its architecture. More cores (14 versus 8), more threads (20 versus 16), a higher boost clock (4.90 GHz versus 4.40 GHz), and a newer process generation all contribute to the measured results. The AMD Ryzen 7 3700X does have a larger L3 cache (32 MB versus 24 MB) and a smaller die size, but these do not translate into benchmark wins.

For users who prioritize raw performance, the Intel Core i5-14500HX is the superior choice. It is also a mobile part, which means it fits into laptops, whereas the AMD is a desktop part. The Intel supports newer memory standards (DDR5) and PCIe Gen 5, while the AMD is limited to DDR4 and PCIe Gen 4. The AMD's only recorded advantage is its launch MSRP of $329, which was set at launch in 2019, but the database records no current pricing information to compare.

Specification Differences

The two processors differ across nearly every recorded specification. The Intel Core i5-14500HX has 14 cores and 20 threads, while the AMD Ryzen 7 3700X has 8 cores and 16 threads. Base clocks are 2.60 GHz for Intel versus 3.60 GHz for AMD, but boost clocks favor Intel at 4.90 GHz versus 4.40 GHz. TDP is 55 W for Intel and 65 W for AMD.

The Intel uses an Intel BGA 1964 socket and a 10 nm process from Intel's foundry, with a die size of 257 mm². The AMD uses an AMD Socket AM4 and a 7 nm process from TSMC, with a die size of 74 mm² and 3,800 million transistors. Cache differs: Intel has 80 KB L1 per core, 2 MB L2 per core, and 24 MB shared L3; AMD has 64 KB L1 per core, 512 KB L2 per core, and 32 MB L3.

Memory support: Intel supports DDR4 and DDR5, AMD supports only DDR4. Both are dual-channel, but only AMD has a recorded memory bandwidth of 51.2 GB/s. ECC memory is supported by Intel but not AMD. PCIe: Intel has Gen 5 with 16 lanes, AMD has Gen 4 with 24 lanes. Integrated graphics: Intel has UHD Graphics 770, AMD has none. Market segment: Intel is mobile, AMD is desktop. Release dates: Intel January 7, 2024; AMD July 6, 2019. Launch MSRP: Intel has none recorded, AMD has $329. Both are unlocked and active.

Where Each One Wins

The Intel Core i5-14500HX wins in every category where both processors have recorded benchmarks. This includes single-core performance, multi-core performance, floating-point math, integer math, physics, data compression, data encryption, extended instructions, prime number finding, random string sorting, and multithreaded workloads. The margins are largest in floating-point math (78%), physics (61.8%), and single-core Cinebench R15 (68.6%), indicating that the Intel part excels in both number-crunching and latency-sensitive tasks.

The AMD Ryzen 7 3700X does not win any shared benchmark. However, it does have attributes that may suit specific use cases. Its smaller die size (74 mm² versus 257 mm²) and lower TDP (65 W versus 55 W, though TDP is not directly comparable across different measurement methodologies) suggest it may be easier to cool in a desktop chassis. The larger L3 cache (32 MB versus 24 MB) could theoretically benefit cache-sensitive workloads, but the recorded benchmarks do not show this advantage materializing. The AMD also supports PCIe Gen 4 with 24 lanes, which offers more PCIe lanes than the Intel's 16 lanes, potentially relevant for multi-GPU or expansion-heavy desktop builds.

For mobile users, the Intel Core i5-14500HX is the only option of the two, as it is a mobile processor with integrated graphics. For desktop users who already own an AM4 motherboard, the AMD Ryzen 7 3700X offers a drop-in upgrade path, but the benchmark data shows it would be slower in every tested workload. Users seeking maximum performance from the recorded data should choose the Intel Core i5-14500HX; users prioritizing expansion capabilities via PCIe lanes may consider the AMD, but they must accept the consistent performance deficit.
