Memory bandwidth favors Intel, with 102.4 GB/s versus AMD's 89.6 GB/s. Both support ECC memory and have unlocked multipliers.

PCIe capabilities differ notably. The Intel part offers Gen 5 with 20 lanes (CPU only), while the AMD part provides Gen 4 with 12 lanes (CPU only). This gives Intel a significant advantage in bandwidth for expansion cards and NVMe storage. The integrated graphics also differ: Intel has Arc Xe-LPG Graphics with 64 execution units, while AMD has the Radeon 860M. The Intel part was released on 2024-10-23, while the AMD part has a later release date of 2026-02-28.

Architecture Differences

The architectural divide is fundamental. The Intel Core Ultra 5 245K uses the Arrow Lake architecture, built on a 3nm process node from TSMC, with a die size of 243 mm² and 17,800 million transistors. The AMD Ryzen AI 7 450G uses the Gorgon Point codename, part of the Ryzen AI 400 generation based on Zen 5 / Zen 5c cores, fabricated on a 4nm process node from TSMC, with a die size of 195 mm². Intel's smaller process node and larger die suggest a more complex design with more transistors, which likely contributes to its higher core count and performance.

Cache organization differs substantially. Intel provides 192 KB of L1 cache per core, 3 MB of L2 per core, and 24 MB of shared L3 cache. AMD offers 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3 cache. Intel's larger cache hierarchy, especially the 24 MB shared L3 versus AMD's 8 MB, provides a clear advantage in workloads that benefit from larger data residency. The core architecture also differs: Intel uses a monolithic Arrow Lake design, while AMD uses a hybrid of Zen 5 and Zen 5c cores, which likely accounts for its different power and thread characteristics.

The AMD part is based on Gorgon Point, which is a derivative of the Phoenix Point design, and is manufactured on a 4nm node. Intel's Arrow Lake-S uses a 3nm node, which allows for higher transistor density and potentially better power efficiency per transistor. Both parts have unlocked multipliers, indicating overclocking support. The Intel part has a higher memory bandwidth (102.4 GB/s versus 89.6 GB/s), which is consistent with its support for faster DDR5 modules.

Where Each One Wins

The Intel Core Ultra 5 245K wins in nearly every computational category measured. It dominates in data compression (12.2% ahead), data encryption (43.1% ahead), extended instructions (25% ahead), prime number finding (79% ahead), floating point math (51.3% ahead), multi-threaded workloads (29.3% ahead), physics simulations (53.3% ahead), random string sorting (22.6% ahead), and single-thread performance (8.6% ahead). These results make it the clear choice for scientific computing, financial modeling, video encoding, and any workload that relies heavily on parallel math or large data sets.

The AMD Ryzen AI 7 450G has only one benchmark win: integer math, where it edges out Intel by 1.2%. This is a narrow victory, and the practical significance is limited. However, the AMD part's strengths lie outside the CPU benchmark suite. It has a much lower TDP (65W versus 125W), which makes it suitable for compact or power-conscious builds. Its integrated Radeon 860M graphics are a notable feature, though the benchmark data does not compare GPU performance. The AMD part also supports LPDDR5X memory, which could be advantageous in mobile or space-constrained systems.

For users building a desktop system focused purely on CPU performance, the Intel Core Ultra 5 245K is the superior choice in every tested workload except integer math. For those who prioritize power efficiency, integrated graphics capability, or the ability to use LPDDR5X memory, the AMD Ryzen AI 7 450G offers distinct platform advantages that are not reflected in these CPU benchmarks. The data supports Intel for raw performance, and AMD for efficiency and integrated features.
