Intel Core i5-1335U (13th Gen) Laptop Processor

The 13th Generation Intel Core i5-1335U is a mid-range processor released in 2023. The i5-1335U delivers a great balance between performance, power consumption and price. With these characteristics, it’s no wonder the CPU is one of the most frequently used laptop processors. You can find it in many mainstream laptop models.

Although it’s not as fast as the high-performance Core H series i5 and i7 processors, the U series Core i5-1335U can effortlessly handle the daily home and office computing tasks. It even offers decent performance for the heavier computing like multimedia creation, while consuming much less battery juice than the computing performance oriented P and H series. The U series consumes 15 Watts as opposed to 28 and 45 Watts or the P and H series.

In the 13th Gen Intel Core U series lineup, the i5-1335U sits between the i3-1315U and i7-1355U. It is faster than the i3, but many benchmarks show it is also slightly faster than the i7. The latter shouldn’t be the case based on the processor hierarchy and the reason for this can be thermal throttling. The i7 has slightly more powerful Intel Xe integrated graphics version, which consumes slightly more power and produces more heat, probably at the expense of the main computing cores.

The main AMD’s competing counterpart of the Intel Core i5-1335U is the AMD Ryzen 5 7530U.
