AMD Ryzen AI 7 450 vs Intel Core i7-14700HX Comparison

Head-to-Head Benchmarks

The head-to-head comparison between the AMD Ryzen AI 7 450 and the Intel Core i7-14700HX is decisive: Intel wins all 15 recorded benchmarks. The AMD processor does not claim a single victory in the database's matched tests. The largest margin is in PassMark's find prime numbers test, where Intel scores 165 against AMD's 89, a 46.1% advantage. This indicates a substantial lead in raw integer-heavy single-threaded workloads.

The second-largest gap appears in floating point math, where Intel scores 93836 versus AMD's 54447, a 42% difference. This suggests that the Intel chip has a significant advantage in scientific or financial calculations that rely on floating-point throughput. Data encryption also favors Intel heavily: 26092 versus 16247, a 37.7% delta. This reflects stronger AES-NI or similar cryptographic instruction execution.

In the widely used Cinebench R15 multicore test, Intel leads with 3812 against AMD's 2713, a 28.8% difference. The single-core version of the same test shows Intel ahead by 27.4% (296 versus 215). These are large margins in both threaded and single-threaded rendering workloads. The Cinebench R23 multicore results follow the same pattern: Intel scores 24595, AMD scores 18316, a 25.5% advantage. However, the R23 single-core test narrows considerably: Intel at 2103, AMD at 2038, only a 3.1% gap.

PassMark integer math shows Intel at 131296 against AMD's 88531, a 32.6% lead. Multithreaded PassMark gives Intel 36566 versus AMD's 26350, a 27.9% difference. Data compression also favors Intel: 438539 versus 315906, a 28% margin. Random string sorting shows Intel ahead by 26.6% (48544 versus 35648). Physics simulation in PassMark gives Intel 2252 versus AMD's 1578, a 29.9% advantage.

Extended instructions in PassMark show a smaller but still clear Intel edge: 25718 versus 22400, a 12.9% delta. The PassMark single-thread test is the closest benchmark overall: Intel at 3947, AMD at 3901, a mere 1.2% difference. This near-tie in single-thread performance stands in contrast to the larger multicore gaps.

The overall average benchmark score confirms the hierarchy: Intel's average is 45953, while AMD's is 39485. The database places Intel in the 89th percentile of all CPUs, with AMD at the 87th percentile. Despite the lopsided head-to-head sweep, both chips sit within a narrow percentile band, indicating that the AMD part remains competitive in the broader CPU landscape.

Where Each One Wins

Based on the recorded data, the Intel Core i7-14700HX wins every workload category where both chips were tested. There is no benchmark in the database where the AMD Ryzen AI 7 450 takes the lead. This includes multi-threaded rendering (Cinebench R15 and R23), all PassMark sub-tests, and single-threaded tests.

The closest contest is the PassMark single-thread test, where Intel is only 1.2% ahead. This suggests that for tasks that rely primarily on single-core performance, such as older games or lightly threaded applications, the two processors are nearly equivalent in practice. The Cinebench R23 single-core test shows a similar pattern, with Intel ahead by just 3.1%.

In contrast, the largest Intel advantages appear in highly parallel or specialized workloads. Floating point math (42% ahead), find prime numbers (46.1%), and data encryption (37.7%) are areas where the Intel chip demonstrates a commanding lead. These are workloads that benefit from a higher core count and potentially better instruction-level parallelism.

For general productivity, the Intel chip leads in integer math by 32.6% and in data compression by 28%. Multithreaded performance in Cinebench R15 and R23 shows Intel ahead by roughly a quarter to a third of AMD's score. The AMD processor does not have a single use case in the data where it wins, so the practical split is simply: Intel for everything measured, with the smallest gap in lightly threaded tasks.

Architecture Differences

The AMD Ryzen AI 7 450 uses the Zen 5 architecture on a 4 nm process, fabricated by TSMC. Its codename is Gorgon Point, and it belongs to the Ryzen AI 400 generation, which combines Zen 5 and Zen 5c cores. The chip has 8 cores and 16 threads. The Intel Core i7-14700HX uses the Raptor Lake architecture on a 10 nm process, fabricated by Intel. Its codename is Raptor Lake-HX, and it is part of the Core 14th Gen series with a Raptor Lake-HX Refresh generation. This chip has 20 cores and 28 threads.

The core count difference is substantial: Intel offers 12 more cores and 12 more threads. This largely explains the multicore benchmark advantages. The base clock for Intel is 2.10 GHz, slightly higher than AMD's 2.00 GHz. The boost clock also favors Intel: 5.50 GHz versus 5.10 GHz. This contributes to the single-thread advantages, though the gap is small in the closest single-thread tests.

Cache configurations differ noticeably. Both chips have 80 KB of L1 per core. The L2 cache is 1 MB per core on AMD, while Intel has 2 MB per core. The L3 cache is a major split: AMD has 8 MB total, while Intel has 33 MB shared. This larger L3 cache on Intel likely aids in workloads that benefit from data locality across many cores.

Process node and die size also differ. AMD's die is 195 mm², while Intel's is 257 mm². The AMD chip uses a 4 nm process, which is more advanced than Intel's 10 nm node. The memory support includes DDR5 and LPDDR5X for AMD, while Intel supports DDR4 and DDR5. AMD's memory bandwidth is listed as 89.6 GB/s, while Intel's is not recorded. Both support ECC memory.

PCIe connectivity differs: AMD uses Gen 4 with 16 lanes (CPU only), while Intel uses Gen 5 with 16 lanes (CPU only). The integrated graphics also differ: AMD has Radeon 860M, Intel has UHD Graphics 770. The Intel chip has an unlocked multiplier, while the AMD chip does not. The sockets are AMD Socket FP8 versus Intel BGA 1964.

The Verdict

The data points to a clear selection for users who prioritize raw multi-threaded performance: the Intel Core i7-14700HX. It leads in every benchmark, with particularly large margins in floating point math, prime number finding, data encryption, and all Cinebench multicore tests. The 20-core configuration versus 8 cores provides a structural advantage that cannot be overcome by AMD's more advanced 4 nm process.

For users whose workloads are predominantly single-threaded, the choice is less obvious. The PassMark single-thread scores are nearly identical (3947 versus 3901), and Cinebench R23 single-core shows only a 3.1% gap. In such cases, the AMD chip may be adequate, but it still does not win any test. The Intel chip is the safer selection across the entire measured workload spectrum.

The AMD Ryzen AI 7 450 does have a lower TDP (28 versus 55) and a smaller die size (195 mm² versus 257 mm²), which may appeal to those who value efficiency or compact designs. However, the database does not include power consumption or thermal benchmarks, so these advantages are not quantified in the recorded data. Based strictly on performance scores, the Intel Core i7-14700HX is the recommended pick for any application where benchmark results are the deciding factor.
