Intel Core i5-1235U
The volume 12th-gen ultrabook processor, found in countless sub-$700 laptops. Two P-cores and eight E-cores cover office work and browsing comfortably, but it was never built for rendering, compiling or sustained multi-core loads.
Pros
- Cheap, everywhere, and fine for office and web work
- Ten cores handle heavy multitasking better than old quad-cores
- Low 15W base power suits thin chassis
- Supports DDR5, LPDDR5 and LPDDR4X
Cons
- Weakest multi-core showing of the 12th-gen mobile line
- 80-EU iGPU is entry level
- Sustained clocks drop quickly in thin laptops
Below average
