AMD Ryzen AI 7 450 vs Intel Core Ultra 5 245HX Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear overall winner: the Intel Core Ultra 5 245HX takes all 15 head-to-head tests, while the AMD Ryzen AI 7 450 wins none. The margins, however, vary widely by workload, which is useful for understanding where each chip has relative strengths.

The largest gap appears in prime number finding. The Intel part scores 359 versus 89 for the AMD, a 75.2% advantage. This is an extreme case, but it illustrates a pattern: the Intel Core Ultra 5 245HX tends to dominate in tasks that stress raw integer throughput and single-thread execution. In Cinebench R23 single-core, the Intel chip scores 4568 against 2038, a 55.4% lead. Cinebench R15 single-core shows a similar story, with 460 versus 215, a 53.3% gap.

Floating-point math also heavily favors Intel. The Intel score of 120735 is 54.9% above the AMD's 54447. Data encryption follows with a 45.9% deficit for the AMD chip (30022 versus 16247). The multi-core Cinebench R23 result is another decisive Intel win: 32358 versus 18316, a 43.4% margin.

Some tests are closer. Integer math shows only a 3.9% difference, with Intel at 92150 and AMD at 88531. Single-thread Passmark results are also relatively tight, at 4481 versus 3901, a 12.9% gap. These narrower margins suggest that in certain mixed workloads, the AMD Ryzen AI 7 450 is more competitive, even if it cannot take the win.

The multi-thread Passmark score gives Intel a 30.8% edge (38069 versus 26350). Cinebench R15 multi-core is a 16.8% gap (3261 versus 2713). Data compression shows Intel ahead by 19.6% (393071 versus 315906). Extended instructions, random string sorting, and physics all land in the 25% to 38% range favoring Intel. The overall average benchmark score for the Intel part is 48287 versus 39485 for the AMD, a difference of about 22%. The Intel chip also sits at the 90th percentile of all CPUs in the database, while the AMD sits at the 87th percentile.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen AI 7 450 uses the Zen 5 architecture with the codename Gorgon Point, part of the Ryzen AI 400 generation that employs a mix of Zen 5 and Zen 5c cores. The Intel Core Ultra 5 245HX is built on Arrow Lake, specifically Arrow Lake-HX, and belongs to the Core Ultra Series 2 generation.

Process node and foundry are shared, both using TSMC, but the node sizes differ. AMD uses a 4 nm process, while Intel uses a 3 nm process. The die sizes also differ, with AMD at 195 mm² and Intel at 243 mm². The Intel chip lists a transistor count of 17,800 million, while the AMD entry has no transistor figure in the database.

Cores and threads show a structural difference. The AMD chip has 8 cores and 16 threads, indicating simultaneous multithreading. The Intel chip has 14 cores and 14 threads, meaning no hyperthreading on this part. Cache layouts differ as well. AMD provides 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3. Intel provides 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3.

Memory support is another differentiator. AMD supports both DDR5 and LPDDR5X, while Intel lists only DDR5. Both use dual-channel memory buses, but bandwidth differs: AMD at 89.6 GB/s and Intel at 102.4 GB/s. ECC memory is supported on the AMD chip but not on the Intel chip. PCIe capabilities also differ, with AMD offering Gen 4 with 16 lanes (CPU only), while Intel offers Gen 5 with 20 lanes (CPU only).

Integrated graphics are present on both. AMD uses the Radeon 860M, while Intel uses Arc Xe-LPG Graphics with 48 execution units. The Intel part has an unlocked multiplier; the AMD part does not. Socket types differ as well, with AMD on AMD Socket FP8 and Intel on Intel BGA 2114. Release dates from the database show Intel released earlier, on 2025-01-12, while AMD's date is listed as 2026-01-04.

The Verdict

The recorded data points to the Intel Core Ultra 5 245HX as the stronger performer across every benchmark in the head-to-head set. Its 90th percentile ranking and average score of 48287 put it ahead of the AMD Ryzen AI 7 450, which sits at the 87th percentile with an average of 39485. The Intel chip also draws close comparisons to desktop-class parts in the database, such as the Intel Core i5-14600K at a delta of -0.7%, while the AMD chip's nearest rivals include the AMD Ryzen 7 9800X3D at -0.7% and the AMD Ryzen 7 PRO 8845HS at 0.4%.

The Intel part offers more cores, more L3 cache, a higher base clock, a larger memory bandwidth, and a smaller process node. It also has an unlocked multiplier, which is notable for a mobile chip. The AMD part counters with simultaneous multithreading, ECC support, LPDDR5X memory support, and a lower TDP of 28 versus 55. That lower TDP suggests the AMD chip is aimed at more power-conscious mobile designs, though the database does not include power draw measurements to confirm this.

For the user who prioritizes raw performance, especially in single-thread and multi-thread compute tasks, the Intel Core Ultra 5 245HX is the clear choice based on this data. For a system where power efficiency and ECC memory are priorities, the AMD Ryzen AI 7 450 has a place, but the performance gap is substantial.

Where Each One Wins

The Intel Core Ultra 5 245HX wins every recorded head-to-head test, so its territory is broad. The largest margins come in prime number finding (75.2%), single-core Cinebench R23 (55.4%), floating-point math (54.9%), single-core Cinebench R15 (53.3%), and data encryption (45.9%). These results indicate that the Intel chip is especially strong in single-threaded workloads and mathematically intensive tasks. Its multi-core Cinebench R23 lead of 43.4% also makes it the better option for rendering and heavily threaded workloads.

The AMD Ryzen AI 7 450, despite having no wins, shows its most competitive results in integer math (3.9% gap) and Passmark single-thread (12.9% gap). These are the areas where the AMD chip comes closest, suggesting that in mixed integer-heavy tasks, the two CPUs are closer than the overall averages imply. The AMD chip also has the advantage of a lower TDP and ECC support, which are not benchmark scores but matter for specific build requirements.

In practical terms, the Intel Core Ultra 5 245HX is the part to select for maximum compute performance in mobile form. The AMD Ryzen AI 7 450 is the more efficient option on paper, with a 28 TDP and LPDDR5X memory support, and it remains viable for workloads where its 16 threads and ECC capability are valued. The benchmark data, however, gives the Intel chip the decisive edge across the board.
