Architectural Differences
Here’s a look at the few minor differences between the two chips.
- Processing Nodes: Although both CPUs use the same nodes, Intel has emphasized improved efficiency in Raptor Lake.
- Clock Speeds: The Core i5-1335U boasts slightly higher boost clock speeds at 4.6GHz for the P-cores and 3.4GHz for the E-cores. In comparison, the Core i5-1235U clocks 4.4GHz for the E-cores and 3.3GHz for the E-cores on boost mode.
- Memory Support: The Core i5-1335U, with its Raptor Lake platform, supports an improved DDR5 transfer speed of up to 6400 MT/s. LPDDR5x support is also added, which the Alder Lake Core i5-1235U does not support.
- iGPU: Another insignificant difference, but the Core i5-1335U adds 50MHz to the GPU boost clock frequency at 1250MHz.
Intel’s 13th Gen Raptor Lake CPUs promised 41% better multi-threaded performance and a 15% improvement in single-threaded performance. Today, we will see if these figures hold any weight as we compare two Core i5 CPUs one generation apart, in Core i5-1335U vs Core i5-1235U.
