Architecture Differences

The AMD Ryzen AI 7 450 is built on the Zen 5 architecture, with the codename Gorgon Point, and belongs to the Ryzen AI 400 generation (Zen 5 / Zen 5c). It uses a 4 nm process from TSMC and has a die size of 195 mm². The Intel Core Ultra 5 245 is built on the Arrow Lake architecture, specifically Arrow Lake-S, and belongs to the Ultra 5 generation. It uses a 3 nm process from TSMC and has a larger die size of 243 mm². The Intel chip contains 17,800 million transistors, while the AMD chip does not have a listed transistor count.

The AMD processor has 8 cores with 16 threads, indicating simultaneous multithreading. The Intel processor has 14 cores with 14 threads, meaning no hyperthreading on any of its cores. The AMD chip's base clock is 2.00 GHz, while the Intel chip starts at 3.50 GHz. Both reach the same 5.10 GHz boost clock. The AMD chip has a 28 W TDP, whereas the Intel chip has a 65 W TDP, reflecting their different market segments: mobile versus desktop.

Cache layouts differ substantially. The AMD chip provides 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3. The Intel chip provides 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3. The L3 advantage for Intel is 3x, which helps in workloads that repeatedly access large datasets.

Memory support also differs. The AMD chip supports DDR5 and LPDDR5X, while the Intel chip supports only DDR5. Both are dual-channel, but the Intel chip has higher memory bandwidth at 102.4 GB/s versus 89.6 GB/s. Both support ECC memory. PCIe connectivity differs: the AMD chip uses Gen 4 with 16 lanes (CPU only), while the Intel chip uses Gen 5 with 20 lanes (CPU only). Integrated graphics differ as well: the AMD chip has Radeon 860M, and the Intel chip has Arc Xe-LPG Graphics 64EU.

The AMD chip uses the AMD Socket FP8, while the Intel chip uses Intel Socket 1851. The AMD chip was released on 2026-01-04, the Intel chip on 2025-01-06. Neither has an unlocked multiplier. The Intel chip has a launch MSRP of $270.

Head-to-Head Benchmarks

The recorded data shows the Intel Core Ultra 5 245 wins all 15 head-to-head benchmark comparisons. The AMD Ryzen AI 7 450 wins none. The margin varies widely by workload.

In Cinebench R23 multicore, the Intel chip scores 32924 versus 18316 for AMD, a delta of -44.4% from AMD's perspective. That is a massive gap, roughly 1.8x the AMD score. Cinebench R23 singlecore shows an even larger relative difference: Intel at 4648 versus AMD at 2038, a delta of -56.2%. The Intel chip is more than 2.2x faster in single-threaded rendering.

Cinebench R15 tells a similar story. Multicore: Intel 3318 versus AMD 2713, delta -18.2%. Singlecore: Intel 468 versus AMD 215, delta -54.1%. The single-core advantage is dramatic, while the multicore gap is smaller but still decisive.

PassMark integer math is the closest contest. Intel scores 91187 versus AMD 88531, a delta of only -2.9%. This indicates that in pure integer arithmetic, the two CPUs are nearly equivalent. The AMD chip's 16 threads help close the gap despite having fewer cores.

PassMark single-thread shows Intel at 4394 versus AMD at 3901, a delta of -11.2%. This is a moderate lead for Intel, far smaller than the Cinebench single-core gap, which suggests the AMD chip performs relatively better on PassMark's single-thread test than on Cinebench's.

PassMark data compression: Intel 400942 versus AMD 315906, delta -21.2%. Data encryption: Intel 30236 versus AMD 16247, delta -46.3%. Extended instructions: Intel 33304 versus AMD 22400, delta -32.7%. Floating-point math: Intel 120548 versus AMD 54447, delta -54.8%. This floating-point result is striking: Intel is more than 2.2x faster, which indicates a substantial advantage in scientific or numerical workloads.

PassMark find prime numbers: Intel 365 versus AMD 89, delta -75.6%. This is the largest relative margin in the entire dataset. The Intel chip is over 4x faster at this specific algorithmic task, which stresses integer operations and branch prediction.

PassMark multithread: Intel 38706 versus AMD 26350, delta -31.9%. PassMark physics: Intel 2569 versus AMD 1578, delta -38.6%. Random string sorting: Intel 49140 versus AMD 35648, delta -27.5%.

The pattern is consistent: the Intel chip wins everywhere, but the margin depends heavily on the instruction mix. The smallest gap is in integer math (under 3%), and the largest is in prime number finding (over 75%). The average benchmark scores reflect this overall dominance: Intel at 48995 versus AMD at 39485.

The Verdict

The data clearly favors the Intel Core Ultra 5 245 for anyone needing maximum compute throughput. It wins every single benchmark in the head-to-head set, with an average score advantage of about 24% over the AMD Ryzen AI 7 450. The Intel chip also holds a higher percentile ranking (90th versus 87th) and sits among rivals like the AMD Ryzen 9 7900 and Intel Core i5-14600K in average score, while the AMD chip sits near the AMD Ryzen 7 9800X3D.

The AMD Ryzen AI 7 450 is not without merit. It offers 16 threads on 8 cores, which helps in integer math where it trails by only 2.9%. Its 28 W TDP is much lower than the Intel's 65 W, and it supports LPDDR5X memory, which is relevant for mobile designs. The AMD chip also has a smaller die (195 mm² versus 243 mm²) and uses a 4 nm process versus Intel's 3 nm.

The Intel chip is the clear performance winner in every measured category. If the workload is rendering, encryption, floating-point math, or any single-threaded application, the Intel Core Ultra 5 245 delivers a decisive advantage. The AMD chip is best suited for scenarios where power efficiency and mobile integration are priorities, but the benchmark data does not show a single test where it outperforms the Intel part.

Where Each One Wins

The Intel Core Ultra 5 245 wins in every recorded benchmark, so the practical question is which workloads benefit most from its advantages. The largest margins appear in floating-point math, prime number finding, and single-core rendering. For 3D rendering, scientific simulation, or any application that relies heavily on FPU throughput, the Intel chip is the stronger choice. The 54.8% lead in floating-point math and the 75.6% lead in prime number finding show a clear architectural edge in compute-heavy tasks.

The Intel chip also wins decisively in data encryption (46.3% ahead) and extended instructions (32.7% ahead). These results suggest that compression, encryption, and SIMD-heavy code run significantly better on the Intel architecture. The multithread score is 31.9% higher, and the physics score is 38.6% higher. The Cinebench R23 multicore result is 44.4% higher, which makes the Intel chip the recommended option for CPU-bound video encoding or batch rendering.

The AMD Ryzen AI 7 450 has no benchmark wins to point to. Its closest performance is in integer math, where it trails by only 2.9%. That means in applications dominated by integer arithmetic, such as database operations or certain compilation tasks, the two chips are almost interchangeable. The AMD chip also has a much lower TDP (28 W versus 65 W), which makes it suitable for thin-and-light laptops where sustained performance is limited by cooling. Its support for LPDDR5X and its smaller die size (195 mm² versus 243 mm²) reinforce its mobile positioning.

For a desktop builder, the Intel Core Ultra 5 245 is the data-backed choice. For a mobile system where power draw and memory flexibility matter more than raw throughput, the AMD Ryzen AI 7 450 can still be justified, but the recorded benchmarks show it is slower in every measured test. The Intel chip also holds the edge in PCIe connectivity with Gen 5 lanes, which future-proofs storage and GPU bandwidth. The AMD chip uses Gen 4, which is a generation behind. Both CPUs support ECC memory, but the Intel chip offers higher memory bandwidth (102.4 GB/s versus 89.6 GB/s).

The single-thread story is particularly lopsided. Cinebench R23 singlecore shows Intel at 4648 versus AMD at 2038, a 56.2% advantage. PassMark single-thread shows a smaller 11.2% gap, but the direction remains the same. Any workload that depends on per-core speed, such as legacy software or lightly threaded games, will respond better to the Intel chip. The AMD chip's 16 threads do not compensate for its lower per-core performance in these tests.

The verdict from the database is unambiguous: the Intel Core Ultra 5 245 wins 15 out of 15 head-to-head comparisons, and the AMD Ryzen AI 7 450 wins none. The average benchmark scores (48995 versus 39485) and percentile rankings (90th versus 87th) both favor Intel. The AMD chip remains a viable mobile option due to its lower TDP and LPDDR5X support, but the performance data offers no scenario where it overtakes the Intel part.
