Comparison of the two processors

Anyone who knows a little about the naming of Intel processors will see at first glance that these two processors are only one generation apart and may even suspect that they should otherwise be quite similar. However, a closer look at the technical data reveals a completely different picture.

The Intel Core i5-1135G7 comes from the eleventh generation of the mobile Core i5 family and is manufactured with a structure width of 10 nanometers. It was launched in the third quarter of 2020 and is based on Intel's Tiger Lake U architecture. As mentioned at the beginning, the Intel Core i5-1235U comes from the twelfth generation of the same family and is therefore already based on the Alder Lake U architecture. It came onto the market in the first quarter of 2022 and is also manufactured with a structure width of 10 nanometers.

The Intel Core i5-1135G7 has 4 identical processor cores, while the Intel Core i5-1235U uses a hybrid core architecture with 2 Golden Cove performance cores and 8 Gracemont efficiency cores. The 4 cores of the Intel Core i5-1135G7 clock at up to 4.20 gigahertz and support hyperthreading, which means a maximum of 8 computing threads are available. The performance cores of the Intel Core i5-1235U clock at a maximum of 4.40 gigahertz and efficiency cores at up to 3.30 gigahertz. Hyperthreading is only supported by the performance cores, meaning the processor has a maximum of 12 computing threads available.

Both processors use Intel Iris Xe Graphics with 80 execution units as the internal graphics unit. In the case of the Intel Core i5-1135G7, however, this iGPU is still based on the Tiger Lake architecture, while the iGPU of the Intel Core i5-1235U is already based on the newer Alder Lake architecture.

Both the Intel Core i5-1135G7 and the Intel Core i5-1235U are equipped with 2 memory channels. They can both be operated with up to 64 gigabytes of RAM, with the Intel Core i5-1135G7 only supporting DDR4 RAM, while the Intel Core i5-1235U also supports DDR5 RAM.
