Architecture Differences

The Intel Core i5-14600K is a desktop part built on Intel's Raptor Lake architecture, specifically the Raptor Lake Refresh generation. It uses a 10 nm process node from Intel's own foundry. The die measures 257 mm². It packs 14 cores and 20 threads, with a base clock of 3.50 GHz and a boost clock of 5.30 GHz. Thermal design power is rated at 125 watts. The chip supports DDR4 and DDR5 memory over a dual-channel bus, and it includes ECC memory support. PCIe connectivity is Gen 5 with 16 lanes from the CPU. Integrated graphics come in the form of UHD Graphics 770. The multiplier is unlocked, allowing overclocking. It launched in October 2023 with a launch MSRP of $319. The cache layout includes 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3.

The AMD Ryzen AI 9 HX PRO 375 is a mobile processor built on the Zen 5 architecture with the codename Strix Point, part of the Ryzen AI PRO 300 generation that mixes Zen 5 and Zen 5c cores. It uses a 4 nm process from TSMC, and the die is 233 mm². It has 12 cores and 24 threads, with a base clock of 2.00 GHz and a boost clock of 5.10 GHz. Thermal design power is dramatically lower at 28 watts. Memory support covers DDR5 and LPDDR5X over a dual-channel bus, with a recorded memory bandwidth of 89.6 GB/s. ECC memory is supported. PCIe is Gen 4 with 16 lanes from the CPU. Integrated graphics are handled by the Radeon 890M. The multiplier is locked. It was released in January 2025. The cache configuration uses 80 KB of L1 per core, 1 MB of L2 per core, and 16 MB of L3.

The key architectural differences are clear. Intel uses a larger, power-hungry desktop design with higher clocks and more physical cores. AMD uses a denser 4 nm process, far lower power draw, and a hybrid Zen 5 / Zen 5c core arrangement. The AMD chip's 28 watt TDP versus Intel's 125 watt TDP is a massive difference in power envelope, yet AMD still wins Cinebench R23 multi-core. That speaks to the efficiency of the Zen 5 architecture. The Intel part counters with a much higher boost clock and a larger L3 cache, 24 MB versus 16 MB. The process node gap, 10 nm versus 4 nm, is also significant and likely explains much of the single-thread performance difference in Cinebench R23.

The Verdict

The data points to two very different buyers. The Intel Core i5-14600K is the stronger overall performer in the majority of recorded benchmarks, winning 13 of 17 tests. It dominates in physics, encryption, compression, and floating point math. For desktop users who need raw multi-threaded throughput in legacy Cinebench R15 and R20 workloads, plus strong integer and floating point math, Intel is the clear choice. Its 30% lead in data encryption and 34.2% lead in physics are hard to ignore for compute-heavy tasks.

The AMD Ryzen AI 9 HX PRO 375 wins where it matters most for modern single-threaded performance. Its 48.7% lead in Cinebench R23 single-core is the single largest margin in the entire comparison. It also wins Cinebench R23 multi-core by 14.2%, which is remarkable given its 28 watt TDP. For mobile users who need efficiency and strong modern rendering performance, AMD is the better pick. The 28 watt power envelope versus 125 watts means the AMD chip fits in entirely different systems.

The overall average benchmark scores are close, 48618 for Intel versus 47022 for AMD, a difference of roughly 3.4%. The percentile rankings are nearly identical, 90th versus 89th. Neither chip is a runaway winner in aggregate. The choice comes down to workload and platform. Desktop builders with power to spare should take Intel. Mobile users and efficiency-focused buyers should take AMD. The AMD chip's Cinebench R23 wins suggest that newer rendering workloads favor Zen 5, while Intel retains advantages in older Cinebench versions and Passmark's computational suite.

Integer math, while closer, still favors Intel by 5.2%. The older Cinebench R15 and R20 multi-core tests also favor Intel by 26.6% and 14.4% respectively, suggesting that legacy rendering workloads run better on the desktop part. The unlocked multiplier on Intel also allows overclocking, which is not available on the locked AMD chip.

The AMD Ryzen AI 9 HX PRO 375 wins in modern single-threaded rendering and efficiency-sensitive workloads. The 48.7% lead in Cinebench R23 single-core is the headline result, and the 26.7% lead in Cinebench R15 single-core reinforces that pattern. Cinebench R23 multi-core also goes to AMD by 14.2%, which is notable for a 28 watt part. Extended instructions run 2.7% faster on AMD, a small but real edge for SIMD-heavy code. The 28 watt TDP means AMD wins in any scenario where power consumption is a constraint, such as thin-and-light laptops or fanless designs. The Radeon 890M integrated graphics also give AMD a stronger integrated GPU option, though the benchmark data does not cover graphics comparisons. For mobile professionals running modern Cinebench R23 workloads, the AMD chip is the better fit. For desktop enthusiasts with access to a dedicated GPU and a robust cooling solution, the Intel part offers more wins across the broader benchmark suite.
