AMD Ryzen 7 7700 vs Intel Core Ultra 7 255H
Last updated:
Summary
The AMD Ryzen 7 7700 (Raphael, Zen 4) is a 5 nm desktop processor from AMD for gaming and demanding applications.
The Intel Core Ultra 7 255H (Arrow Lake H) is a 3 nm mobile processor from Intel for powerful, efficient notebooks.
The AMD Ryzen 7 7700 features 8 MB L2 and 32 MB L3 Cache, PCIe 5.0, and 83 GB/s memory bandwidth. The Intel Core Ultra 7 255H has 6 MB L2 and 24 MB L3 Cache, as well as 134 GB/s memory bandwidth. According to internal analyses based on Geekbench 6, both processors show comparable single-core and multi-core performance.
For gaming, the AMD Ryzen 7 7700 desktop processor with PCIe 5.0 and a dedicated graphics card is more powerful. Its integrated AMD Radeon Graphics (Raphael) serves basic tasks. The mobile Intel Core Ultra 7 255H with Intel Arc 140T graphics is designed for energy efficiency and is suitable for casual gaming in laptops.
The AMD Ryzen 7 7700 as a desktop CPU can exhibit higher thermal design power (TDP). The Intel Core Ultra 7 255H is designed for optimized energy efficiency in mobile systems due to its 3 nm manufacturing process. The price-performance ratio depends on the system context: AMD for upgradeable desktops, Intel as an integral part of laptops.
Summary and Recommendation: The AMD Ryzen 7 7700 is ideal for powerful, expandable desktop PCs with a separate graphics card for gaming and content creation. The Intel Core Ultra 7 255H is the suitable choice for notebooks that should offer balanced performance and high energy efficiency for productivity and mobile gaming.
