AMD Ryzen AI 5 435 vs Intel Core i5-14450HX Comparison

The AMD Ryzen AI 5 435 and the Intel Core i5-14450HX are both mobile processors aimed at high-performance laptops, but the recorded benchmark data shows a clear and consistent winner in almost every category. The Intel Core i5-14450HX dominates the comparison, winning 13 of the 15 head-to-head benchmark tests, with the AMD Ryzen AI 5 435 securing only two wins, both in single-threaded Passmark tests. The average benchmark scores confirm the gap: Intel’s chip records an average score of 32040, while AMD’s processor averages 28128. This places the Intel part in the 82nd percentile of all CPUs, versus the 80th percentile for the AMD chip, indicating a modest but real performance tier difference.

Head-to-Head Benchmarks

The most decisive result in the entire comparison comes from the Cinebench R23 multi-core test. The Intel Core i5-14450HX scores 20108, while the AMD Ryzen AI 5 435 scores 11333. That is a delta of -43.6 percent from AMD’s perspective, meaning Intel’s chip is roughly 77 percent faster in this heavy multi-threaded workload. This is the single largest performance gap between the two processors in any recorded test. The Cinebench R15 multi-core test tells a similar story, though with a smaller margin: Intel scores 2026 versus AMD’s 1686, a delta of -16.8 percent.

Single-core performance is also a clear Intel advantage in the Cinebench suite. In Cinebench R23 single-core, Intel records 2838 against AMD’s 1816, a delta of -36 percent. The Cinebench R15 single-core test shows Intel at 285 versus AMD’s 260, a delta of -8.8 percent. These results indicate that Intel’s architecture delivers substantially higher performance per core in rendering workloads, not just more cores.

The Passmark suite reveals a similar pattern across most tests. In integer math, Intel scores 78330 versus AMD’s 61026, a delta of -22.1 percent. Floating point math shows Intel at 58037 against AMD’s 40627, a delta of -30 percent. Data compression favors Intel at 278538 versus 225374, a delta of -19.1 percent. Data encryption also goes to Intel: 15574 versus 11110, a delta of -28.7 percent. The largest Passmark gap is in prime number finding, where Intel scores 98 against AMD’s 58, a delta of -40.8 percent.

The only two tests where the AMD Ryzen AI 5 435 comes out ahead are the Passmark single-thread and singlethread tests, which appear to be the same measurement recorded twice. In those tests, AMD scores 3734 while Intel scores 3643, giving AMD a 2.5 percent advantage. This is a narrow win, and it stands in contrast to the Cinebench single-core results, where Intel leads by double-digit percentages. The discrepancy suggests that the Passmark single-thread test measures a different mix of instructions that favors AMD’s Zen 5 core design, while Cinebench’s rendering workload favors Intel’s higher boost clock and architecture.

Other Passmark tests follow the Intel trend. Extended instructions go to Intel at 17207 versus 16197, a delta of -5.9 percent, the closest margin in the entire comparison. Multithread scores show Intel at 23680 versus AMD’s 19000, a delta of -19.8 percent. Physics tests favor Intel at 1475 versus 1075, a delta of -27.1 percent. Random string sorting also goes to Intel: 29565 versus 24891, a delta of -15.8 percent.

Architecture Differences

The two processors are built on fundamentally different architectures and process technologies. The AMD Ryzen AI 5 435 uses the Zen 5 architecture, with the codename Gorgon Point, and belongs to the Ryzen AI 400 generation, which combines Zen 5 and Zen 5c cores. It is manufactured on a 4 nm process node at TSMC. The Intel Core i5-14450HX uses the Raptor Lake architecture, specifically Raptor Lake-HX, part of the Core 14th Gen series, and is built on a 10 nm process node at Intel’s own foundries. This process difference is significant: AMD’s 4 nm node is considerably more advanced than Intel’s 10 nm node, which should confer power and density advantages, but the benchmark data shows Intel still leads in performance across most tests.

Core and thread counts differ substantially. The AMD chip has 6 cores and 12 threads, while the Intel chip has 10 cores and 16 threads. This gives Intel a 4-core and 4-thread advantage, which is the most likely explanation for its large multi-core benchmark leads. The base clock speeds also differ: AMD runs at 2.00 GHz, while Intel runs at 2.40 GHz. Boost clocks show a similar gap, with AMD reaching 4.50 GHz and Intel reaching 4.80 GHz.

Cache configurations are another major differentiator. Both chips have 80 KB of L1 cache per core. The L2 cache is 1 MB per core on the AMD chip, but 2 MB per core on the Intel chip, giving Intel double the L2 cache per core. The L3 cache shows an even larger disparity: AMD has only 4 MB of L3 cache, while Intel has 20 MB of shared L3 cache. This fivefold difference in L3 capacity likely contributes to Intel’s advantage in workloads that benefit from larger cache pools, such as the data compression and encryption tests.

The power envelope is also very different. The AMD Ryzen AI 5 435 has a TDP of 28 watts, while the Intel Core i5-14450HX has a TDP of 55 watts. This makes Intel a much more power-hungry part, which is consistent with its higher core count and clock speeds. The AMD chip’s lower TDP, combined with its 4 nm process, suggests it is designed for more power-efficient systems, even if the benchmark data shows it losing on raw performance.

Memory support varies as well. AMD supports DDR5 and LPDDR5X memory, with a dual-channel bus and a recorded memory bandwidth of 89.6 GB/s. Intel supports DDR4 and DDR5 memory, also with a dual-channel bus, but no memory bandwidth figure is recorded for Intel in the database. Both chips support ECC memory. PCIe connectivity differs: AMD offers PCIe Gen 4 with 14 lanes (CPU only), while Intel offers PCIe Gen 5 with 16 lanes (CPU only). This gives Intel a newer PCIe standard and more lanes.

The integrated graphics are different as well. AMD uses the Radeon 840M, while Intel uses UHD Graphics 710. The database does not record any graphics benchmark scores for either chip, so no performance comparison can be made from this data. The Intel chip has an unlocked multiplier, meaning it can be overclocked, while the AMD chip does not. Intel’s die size is recorded at 257 mm², while no die size is recorded for AMD.

Where Each One Wins

The Intel Core i5-14450HX wins in every multi-threaded workload recorded, and in nearly every single-threaded workload as well. Its 10 cores and 16 threads, combined with 20 MB of L3 cache, give it a commanding lead in rendering, encryption, compression, physics, and general math operations. The Cinebench R23 multi-core result, where Intel leads by 43.6 percent, is the clearest indicator that this chip is the better choice for heavy parallel workloads. Its 4.80 GHz boost clock also helps it win the Cinebench single-core tests, where it beats AMD by 36 percent in R23 and 8.8 percent in R15.

The AMD Ryzen AI 5 435 wins only in the Passmark single-thread test, with a 2.5 percent edge over Intel. This narrow victory suggests that AMD’s Zen 5 architecture has a slight advantage in certain lightweight, single-threaded instruction sequences, but it is not enough to overcome Intel’s advantages elsewhere. The AMD chip also has a much lower TDP of 28 watts, which means it will generate less heat and likely consume less power in sustained workloads, but the database records no power consumption measurements beyond TDP figures.

For users running software that relies on integer math, floating point math, data compression, or encryption, the Intel chip is the clear winner, with deltas ranging from -19.1 percent to -30 percent. For users running physics simulations or prime number calculations, Intel’s advantage grows to 27.1 percent and 40.8 percent, respectively. Even in the closest Passmark test, extended instructions, Intel leads by 5.9 percent.

The Verdict

The data indicates that the Intel Core i5-14450HX is the superior processor for almost all workloads. It wins 13 of 15 head-to-head tests, including every Cinebench test and every Passmark test except the single-thread variant. Its higher core count, larger L2 and L3 caches, and higher boost clock give it a decisive edge in both multi-threaded and single-threaded rendering workloads. The 43.6 percent lead in Cinebench R23 multi-core is the most striking finding, and it suggests that anyone running CPU-intensive tasks like video rendering, 3D modeling, or scientific computing should prefer the Intel chip.

The AMD Ryzen AI 5 435 is not without merit. Its 2.5 percent win in Passmark single-thread shows that its Zen 5 core is competitive in at least one narrow measurement, and its 28 watt TDP is much lower than Intel’s 55 watt TDP, which could be important for thin-and-light laptops where thermal headroom is limited. However, the benchmark data does not record any power efficiency measurements, so the practical impact of the TDP difference cannot be quantified here. The AMD chip’s 4 nm process node is more advanced than Intel’s 10 nm node, but this does not translate into performance wins in the recorded tests.

For a buyer choosing between these two mobile processors, the Intel Core i5-14450HX is the stronger choice based on performance data alone. Its wins are not marginal; they are substantial, with double-digit deltas in most tests. The only scenario where the AMD chip appears preferable is one where the lower TDP is critical and the workload is limited to the specific single-threaded Passmark test, but even then, the performance difference is small. The average benchmark scores reinforce this: Intel at 32040 versus AMD at 28128, a gap of roughly 14 percent.
