AMD Ryzen 9 8945HS vs Intel Core i5-14450HX Comparison

Where Each One Wins

The AMD Ryzen 9 8945HS and Intel Core i5-14450HX split their benchmark wins along a clear workload boundary. The AMD part wins 10 of the 15 recorded head-to-head comparisons, while the Intel part takes 5. The AMD Ryzen 9 8945HS dominates in data processing, cryptography, and general multi-threaded throughput. The Intel Core i5-14450HX counters with superior single-core rendering performance in Cinebench and a slim edge in prime number computation and physics simulation.

The AMD Ryzen 9 8945HS is the choice for data-heavy workloads. Its largest margins come in passmark_extended_instructions, where it leads by 56.7%, and passmark_random_string_sorting, where it leads by 46.1%. Data encryption also favors AMD decisively, with a 36.9% advantage. Integer math and data compression follow at 29.2% and 28% respectively. The pattern is consistent: the AMD chip processes structured data faster, whether the task involves sorting, encryption, or extended instruction sets.

The Intel Core i5-14450HX claims its biggest win in Cinebench R23 single-core, where it leads by 36.4%. It also leads by 16.5% in Cinebench R23 multi-core, a notable reversal given the AMD chip's strong Passmark multi-thread result. The Intel part wins Cinebench R15 single-core by a marginal 1.4%, wins passmark_find_prime_numbers by 6.1%, and takes passmark_physics by 2.8%. These wins cluster around single-threaded rendering and scalar computation.

The AMD chip also holds the advantage in Passmark single-thread tests, winning passmark_single_thread by 5.7%, so the single-core picture is not uniform. The Intel part performs better specifically in Cinebench's single-core workload while the AMD part performs better in Passmark's single-thread workload. The Cinebench R15 multi-core test shows AMD ahead by 30.3%, which contrasts sharply with the R23 multi-core result where Intel leads by 16.5%.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen 9 8945HS uses 8 cores and 16 threads, while the Intel Core i5-14450HX uses 10 cores and 16 threads. Intel reaches the same thread count through a hybrid arrangement, but the database does not specify the core mix ratio. Both chips feature 16 threads, so multi-threaded scaling depends on per-core architecture and clock behavior rather than raw thread availability.

The process node differs substantially: AMD uses TSMC's 4 nm process on a 178 mm² die with 25,000 million transistors. Intel uses its own 10 nm process on a larger 257 mm² die with no transistor count listed in the database. The AMD chip has 16 MB of L3 cache shared across 8 cores, plus 1 MB per-core L2 cache per core and 64 KB per-core L1 cache per core. The Intel chip has 20 MB of L3 shared across the chip, 2 MB per core L2 cache per core, and 80 KB per core L1 cache per core.

The memory subsystem also differs: AMD supports DDR5 only with dual-channel support and a memory bandwidth of 89.6 GB/s. Intel supports DDR4 and DDR5 with dual-channel support but no bandwidth figure recorded. Intel includes ECC memory support while AMD does not. PCIe connectivity differs: AMD provides Gen 4 with 20 lanes from the CPU, Intel provides Gen 5 with 16 lanes from the CPU.

Both chips are mobile parts with active production status. The AMD Ryzen 9 8945HS comes from the 8000 series and uses the Zen 4 architecture under the Hawk Point codename. The Intel Core i5-14450HX comes from the Core 14th Gen series and uses Raptor Lake architecture under the Raptor Lake-HX codename. The AMD chip has a base clock of 4.00 GHz and a boost clock of 5.20 GHz. The Intel chip has a base clock of 2.40 GHz and a boost clock of 4.80 GHz.

The AMD chip has a 45 W TDP against Intel's 55 W TDP. The AMD chip uses AMD Socket FP8 while the Intel chip uses Intel BGA 1964. The AMD chip integrates Radeon 780M graphics while the Intel chip integrates UHD Graphics 710. The AMD chip does not have an unlocked multiplier; the Intel chip does.

The AMD chip is the right pick for users whose tasks involve sorting large datasets, cryptographic operations, or extended instruction set usage, where it leads by margins between 28% and 56.7%.

The Core i5-14450HX suits workloads that depend on Cinebench-style rendering performance. The Intel chip leads by 36.4% in Cinebench R23 single-core and by 16.5% in Cinebench R23 multi-core, which suggests it handles rendering pipelines more effectively despite the AMD chip's higher boost clock and smaller process node. The Intel part also edges out AMD in prime number finding and physics simulation, though by smaller margins of 6.1% and 2.8%.

Users should also weigh the platform-level differences. The AMD chip offers a higher boost clock of 5.20 GHz versus 4.80 GHz, a 45 W TDP versus 55 W, and a 4 nm process versus Intel's 10 nm.

The average benchmark score favors Intel by roughly 3%, at 32040 versus 31074, which reflects the Intel chip's stronger Cinebench results pulling its average up. Both chips sit at the same 82nd percentile, so neither represents a dramatic class difference in overall CPU hierarchy.

For data-centric mobile workloads, the Ryzen 9 8945HS is the stronger choice. For rendering-focused workloads with an emphasis on Cinebench scores, the Core i5-14450HX wins. The remaining differences come down to platform preferences: AMD's efficiency-oriented design versus Intel's higher cache and PCIe Gen 5 support.
