AMD Ryzen AI 7 450G vs Intel Core i9-14900F Comparison

The AMD Ryzen AI 7 450G and the Intel Core i9-14900F are two desktop processors with very different design philosophies. The AMD chip uses a modern 4 nm process with a hybrid core layout, while the Intel chip is a high-core-count part on a more mature node. The benchmark data shows a clear split: the Intel i9-14900F wins every recorded test, but the margins vary widely depending on the workload.

Where Each One Wins

The head-to-head data is decisive: the Intel Core i9-14900F wins 11 out of 11 recorded benchmarks. There is no single test where the AMD Ryzen AI 7 450G takes the lead. However, the size of the Intel advantage is not uniform, and that tells the real story.

The Intel chip wins by overwhelming margins in heavily multithreaded and parallel workloads. In passmark_data_compression, the i9-14900F scores 564207 against 402831 for the AMD chip, a 28.6% gap. The divide grows wider in passmark_integer_math, where Intel scores 177066 against 99732, a 43.7% delta. The largest single gap appears in passmark_find_prime_numbers, where Intel scores 209 versus 87, a 58.4% deficit for the AMD part.

The AMD Ryzen AI 7 450G is not competitive in raw throughput tests, but the single-threaded results are much closer. In passmark_single_thread, the Intel chip scores 4506 versus 4309 for AMD, a margin of only 4.4%. This indicates that for lightly threaded tasks, the two processors are nearly equivalent. The AMD chip also shows relative strength in passmark_extended_instructions, where the Intel lead shrinks to 9.2% (31084 versus 28223).

Architecture Differences

The two processors come from opposite architectural approaches. The AMD Ryzen AI 7 450G is built on a 4 nm TSMC process, codenamed Gorgon Point, and belongs to the Ryzen AI 400 generation using a mix of Zen 5 and Zen 5c cores. It has 8 cores and 16 threads. The Intel Core i9-14900F is a Raptor Lake Refresh part, built on Intel's 10 nm process, with 24 cores and 32 threads.

Cache configurations differ significantly. Both chips have 80 KB of L1 per core, but the L2 cache differs: the AMD chip has 1 MB per core, while the Intel chip has 2 MB per core. The L3 cache is a major differentiator. The AMD part has 8 MB total, while the Intel part has 36 MB shared. That larger L3 cache likely contributes to the Intel chip's advantages in compression and sorting workloads.

Memory support also diverges. The AMD chip supports DDR5 and LPDDR5X with dual-channel memory and a recorded bandwidth of 89.6 GB/s. The Intel chip supports DDR4 and DDR5 with dual-channel memory, but no bandwidth figure is recorded in the database. The AMD chip has integrated Radeon 860M graphics, while the Intel chip has no integrated graphics (listed as N/A). The AMD chip uses PCIe Gen 4 with 12 lanes from the CPU, while the Intel chip uses PCIe Gen 5 with 16 lanes.

Both chips have a 65 W TDP and support ECC memory. The AMD chip is socketed for AMD Socket AM5 and has an unlocked multiplier. The Intel chip uses Intel Socket 1700 and has a locked multiplier. The Intel chip has a launch MSRP of $524, while the AMD chip has no recorded launch MSRP.

The Verdict

The benchmark data indicates a clear choice for users who prioritize raw multithreaded performance: the Intel Core i9-14900F delivers substantially higher scores across all recorded tests. The Intel chip is 34.6% ahead in passmark_multithread (46532 versus 30422) and 50.3% ahead in passmark_physics (2899 versus 1440). For rendering, encoding, or any workload that scales across cores, the Intel chip is the stronger option.

The AMD Ryzen AI 7 450G holds its own in single-threaded work, with only a 4.4% gap in passmark_single_thread. It also includes integrated graphics, which the Intel chip lacks entirely. Users who need a processor with a built-in GPU and do not plan to run heavily parallel workloads will find the AMD chip sufficient. The AMD part also uses a smaller 4 nm process and a newer core generation, which could matter for power efficiency, though no power draw numbers are recorded here.

The overall average benchmark scores reflect this hierarchy. The AMD chip has an average score of 63331 and sits at the 93rd percentile of all CPUs. The Intel chip has an average score of 60008 and sits at the 92nd percentile. The AMD chip actually has a higher average score despite losing every head-to-head test, which indicates that the two processors are close in overall performance when considering a broader benchmark set. The Intel chip's nearest rivals include the AMD Ryzen 9 7945HX (0.2% faster) and the AMD Ryzen 7 8745HX (0.2% faster), while the AMD chip's nearest rivals include the Intel Core Ultra 7 265HX (0.2% slower) and the AMD Ryzen AI Max PRO 390 (0.7% faster).

The data encryption test shows a 45.3% lead for Intel (34644 versus 18937). Multithreaded throughput shows a 34.6% gap in favor of Intel (46532 versus 30422). Random string sorting gives Intel a 33.1% edge (63728 versus 42663). Data compression shows a 28.6% gap (564207 versus 402831).

The closest result is passmark_extended_instructions, where Intel scores 31084 versus 28223, a 9.2% margin. The single-threaded tests are the tightest: both passmark_single_thread and passmark_singlethread show Intel at 4506 versus AMD at 4309, a 4.4% delta.

The Intel chip's 24-core count and 36 MB L3 cache appear to drive its dominance in parallel workloads. The AMD chip's 8 cores are simply outmatched in tests that scale with thread count. The single-threaded results show that the Zen 5 core design is competitive per-core, but the Intel chip still edges ahead.

Specification Differences

The process node separates the two: AMD uses 4 nm TSMC fabrication, while Intel uses 10 nm. The die sizes also differ, with the AMD chip at 195 mm² and the Intel chip at 257 mm². The AMD chip belongs to the Ryzen AI 400 generation with the Gorgon Point codename, while the Intel chip is part of the Core 14th Gen series with the Raptor Lake-R codename.

The cache hierarchy differs in L2 and L3. AMD provides 1 MB L2 per core, while Intel provides 2 MB per core. The L3 cache is 8 MB on the AMD chip versus 36 MB shared on the Intel chip. The memory bandwidth shows 89.6 GB/s for the AMD chip, while no bandwidth figure is recorded for the Intel chip.
