Architecture Differences

The AMD Ryzen AI 7 450 is built on the Zen 5 architecture with the codename Gorgon Point, belonging to the Ryzen AI 400 generation which combines Zen 5 and Zen 5c cores. It uses a 4 nm process from TSMC with a die size of 195 mm². The Intel Core i5-14450HX uses the Raptor Lake architecture with the codename Raptor Lake-HX, part of the Core 14th Gen series and specifically the Raptor Lake-HX Refresh generation. Intel fabricates this chip on a 10 nm process with a die size of 257 mm².

Core configurations differ significantly. The AMD processor has 8 cores and 16 threads, while the Intel processor has 10 cores and 16 threads. Both processors share the same thread count, but the Intel part does so with two additional physical cores. Base clocks are 2.00 GHz for the AMD chip and 2.40 GHz for the Intel chip. Boost clocks tell a different story: the AMD chip reaches 5.10 GHz, while the Intel chip tops out at 4.80 GHz.

Cache hierarchies also diverge. Both processors use 80 KB of L1 cache per core and 1 MB of L2 cache per core for the AMD chip, but the Intel chip doubles the L2 to 2 MB per core. The L3 cache favors Intel substantially: 20 MB shared on the Intel chip versus 8 MB on the AMD chip. The AMD processor uses a dual-channel memory bus supporting DDR5 and LPDDR5X with a measured memory bandwidth of 89.6 GB/s, while the Intel processor supports DDR4 and DDR5 with no memory bandwidth figure recorded. Both support ECC memory.

PCIe capabilities differ by generation. The AMD chip provides Gen 4 with 16 lanes (CPU only), while the Intel chip provides Gen 5 with 16 lanes (CPU only). Integrated graphics also differ: the AMD Ryzen AI 7 450 uses the Radeon 860M, and the Intel Core i5-14450HX uses UHD Graphics 710. The Intel chip has an unlocked multiplier, whereas the AMD chip does not. The AMD processor uses AMD Socket FP8, and the Intel processor uses Intel BGA 1964.

Head-to-Head Benchmarks

The recorded data shows a clear split between workloads favoring each processor. The AMD Ryzen AI 7 450 dominates the PassMark suite, while the Intel Core i5-14450HX takes the Cinebench single-core tests and one multi-core test.

Starting with Cinebench, the Intel chip wins Cinebench R15 single-core by 24.6% (285 versus 215) and Cinebench R23 single-core by 28.2% (2838 versus 2038). In Cinebench R23 multi-core, Intel leads 20108 versus 18316, an 8.9% margin. However, in Cinebench R15 multi-core, the AMD chip reverses the trend with a substantial 33.9% lead (2713 versus 2026). This mixed result suggests the older R15 test benefits the AMD architecture more than the newer R23 test.

In PassMark tests, the AMD Ryzen AI 7 450 wins eight of the ten recorded comparisons. The largest AMD margin comes in extended instructions, where it scores 22400 versus 17207 for Intel, a 30.2% advantage. Data compression also favors AMD decisively: 315906 versus 278538, a 13.4% lead. Integer math shows AMD ahead by 13% (88531 versus 78330). Random string sorting goes to AMD by 20.6% (35648 versus 29565). The AMD chip also wins multithread with 26350 versus 23680 (11.3%), physics with 1578 versus 1475 (7%), data encryption with 16247 versus 15574 (4.3%), and single-thread with 3901 versus 3643 (7.1%).

The Intel processor wins two PassMark tests: find prime numbers by 9.2% (98 versus 89) and floating point math by 6.2% (58037 versus 54447). These wins show Intel retains strength in specific numerical workloads even where AMD dominates the broader PassMark suite.

The overall win count of 10 for AMD and 5 for Intel aligns with the average benchmark scores, where AMD leads by 7445 points (39485 versus 32040). The AMD chip outperforms its nearest rival by a similar order of magnitude, while the Intel chip sits within 1% of several comparable Intel processors.

The TDP difference is notable: 28 W for the AMD chip versus 55 W for the Intel chip. This indicates the AMD processor targets a lower power envelope while delivering higher boost clocks. The Intel chip compensates with more cores, larger caches, and an unlocked multiplier.

The Verdict

The data presents two distinct usage profiles. The AMD Ryzen AI 7 450 delivers higher average benchmark performance (39485 versus 32040) and wins 10 of 15 head-to-head tests, with particular strength in integer math, data compression, extended instructions, and random string sorting. Its lower TDP of 28 W, combined with a 5.10 GHz boost clock and 4 nm process, indicates efficiency-focused design. Systems using this processor benefit from newer PCIe Gen 4 (though Intel offers Gen 5), higher memory bandwidth (89.6 GB/s recorded), and a more capable integrated GPU in the Radeon 860M.

The Intel Core i5-14450HX wins in Cinebench R23 multi-core by 8.9% and dominates single-core Cinebench tests by 24.6% and 28.2%. It also leads in prime number finding and floating point math. The 10-core configuration with 20 MB of L3 cache and 2 MB L2 per core gives it a cache advantage, and the unlocked multiplier allows manual overclocking. However, its 55 W TDP suggests higher power consumption for those gains.

The recorded data suggests the AMD Ryzen AI 7 450 suits mixed workloads with heavy integer operations, compression, and parallel threading where its PassMark multithread score of 26350 leads the Intel chip's 23680 by 11.3%. The Intel Core i5-14450HX suits single-threaded responsiveness and specific floating-point or prime-number workloads, where its Cinebench R23 single-core score of 2838 versus 2038 provides a 28.2% edge. Buyers focused on overall benchmark averages should note the AMD chip's 23.2% higher average score (39485 versus 32040), while those prioritizing the Intel chip's specific strengths in Cinebench multi-core will find a narrower 8.9% advantage there.
